RESUMO
Introduction and objective: The approach to patients with advanced or metastatic high-grade epithelial ovarian cancer (EOC) has evolved over time with the advent of new therapies and multimodal strategies. The objective of this consensus of experts is to generate national recommendations for the profiling and management of advanced or metastatic high-grade OEC, defined as stages III and IV of the "The International Federation of Gynecology and Obstetrics (FIGO) classification at the time of diagnosis to base on the literature review that included international evidence-based clinical practice guidelines (CPG). Material and methods: Eleven panelists (oncologists and gynecological oncologists) answered 8 questions about the profiling and management of advanced or metastatic ovarian epithelial carcinoma. The panelists were chosen for their academic profile and influence in national health institutions. Guidelines from the "ESMO Standardized Operating Procedures Consensus Conference" were used to develop the consensus. It was agreed that the level of agreement to accept a recommendation should be ≥ 80%. The document was peer reviewed. Results: Eight general recommendations are made, which are presented into five domains. Some of these recommendations are subdivided into specific recommendations. Initial treatment Recommendation 1.1 Complete primary cytoreduction (PCS) surgery is suggested as the initial therapy of choice for patients with high-grade or metastatic EOC, which should ideally be carried out in centers with experience, followed by adjuvant therapy. 1.2 Neoadjuvant chemotherapy followed by interval cytoreduction surgery (ICS) is suggested in those who are unlikely to achieve a complete cytoreduction in PCS either due to unresectable metastatic disease or who present unresectability criteria (imaging, laparoscopic and/or by laparotomy) and that have been defined by a gynecological oncologist and patients with poor functional status and comorbidities according to the criteria of the multidisciplinary team (clinical oncology, gynecological oncology, radiology, etc.). Recommendation 2. In patients with high-grade epithelial ovarian cancer (EOC), in stage III locally advanced or metastatic, who received neoadjuvant chemotherapy and achieved a complete or partial response (cytoreduction with tumor residue < 2.5 mm), the use of Hyperthermic IntraPeritoneal Chemotherapy (HIPEC) could be considered as an alternative to standard platinum-based adjuvant intravenous chemotherapy during interval cytoreductive surgery, after discussion in a multidisciplinary tumor board, at a center experienced in treating this type of patients. Use of genetic testing. Recommendation 3. It is suggested at the time of diagnosis to offer molecular genetic testing to all patients with high-grade advanced or metastatic EOC regardless of family history. Recommendation 4. It is suggested to offer genetic counseling, by qualified personnel, to all patients with high-grade advanced or metastatic EOC who are ordered genetic testing. Recommendation 5. It is suggested that all patients with advanced or metastatic high-grade EOC undergo a germ panel that includes the Breast Cancer Susceptibility Genes 1/2 genes (BRCA 1/2) and the other susceptibility genes according to with institutional protocols and the availability of genetic testing panels; If it is negative, then somatic testing should be performed that includes the homologous recombination deficiency (HRD) status, regardless of family history. Adjuvant Therapy Recommendation 6. 6.1. It is suggested that all patients with advanced stage III/IV EOC, with PSC of (0-2), got adjuvant intravenous chemotherapy as standard treatment within six weeks after Prc. It is suggested paclitaxel/carboplatin. Recommendation 6.2. It is suggested to use standard chemotherapy base on platinum plus Bevacizumab as adjuvant chemotherapy to patients with high-risk disease (EOC stage IV or stage III with suboptimal tumor cytoreduction), following by bevacizumab as maintenance. The use of bevacizumab as maintenance therapy is not recommended if bevacizumab was not included in the first line of treatment. We suggested the dose used in GOG-0218 and ICON7 trials. Recommendation 6.3 It is suggested combined intravenous/intraperitoneal chemotherapy only for selected patients, with optimal cytoreduction (residual lesions < 1 cm), especially those without residual disease (R0) and who are evaluated in a multidisciplinary meeting. It is not considered standard treatment. Recommendation 6.4. 6.4.1 It is suggested to use Poly ADP ribose polymerase (PARP) inhibitors such as olaparib or niraparib as maintenance after receiving first-line chemotherapy in patients with stage III/IV BRCA1/2 positive EOC who received platinumbased chemotherapy and obtained complete response/partial response (CR/PR), 6.4.2 It is suggested to use olaparib alone or in combination with bevacizumab or niraparib in patients with stage III/IV BRCA1/2 positive EOC who received platinum-based chemotherapy plus bevacizumab and achieved CR/PR. 6.4.3 It is suggested to use niraparibin patients with stage III/IV BRCA1/2 negative or unknown EOC who received platinum-based chemotherapy and achieved CR/PR. 6.4.4 It is suggested to use bevacizumab or olaparib plus bevacizumab in patients with EOC stage III/IV BRCA1/2 negative or unknown (HRD positive) who received platinum-based chemotherapy plus bevacizumab and obtained CR/PR. Treatment of disease relapse Recommendation 7. Secondary cytoreductive surgery followed by chemotherapy is suggested for selected patients with high-grade advanced EOC in first relapse, platinum-sensitive (platinum-free interval ≥ 6 months), positive "Arbeitsgemeinschaft Gynäkologische Onkologie AGO" score or "I-model" positive (< 4.7) with a potential resection to R0 in centers with access to optimal surgical and postoperative support. Note: Platinum-free interval and AGO score have only been developed as positive predictors of complete resection and not to exclude patients from surgery. Recommendation 8. 8.1 For patients with relapse advanced high-grade EOC platinum-sensitive, the following is suggested: Platinum-based combination chemotherapy: carboplatin/liposomal doxorubicin or carboplatin/paclitaxel or carboplatin/nab-paclitaxel or carboplatin/docetaxel or carboplatin/gemcitabine) for six cycles. If combination therapy is not tolerated, give carboplatin or cisplatin alone. Combination chemotherapy (carboplatin/gemcitabine or carboplatin/paclitaxel or carboplatin/doxorubicin liposomal) plus bevacizumab followed by bevacizumab as maintenance (until progression or toxicity). Recommendation 8.2 For patients with relapsed advanced high-grade EOC platinum-resistant, it is suggested: Sequential treatment with chemotherapy, preferably with a non-platinum single agent (weekly paclitaxel or pegylated liposomal doxorubicin or docetaxel or oral etoposide or gemcitabine or trabectidine or, topotecan). Weekly paclitaxel or pegylated liposomal doxorubicin or topotecan could be administrate with or without bevacizumab. Other agents are considered potentially active (capecitabine, cyclophosphamide, ifosfamide, irinotecan, oxaliplatin, pemetrexed, vinorelbine, cyclophosphamide) could be recommended for later lines. Hormone receptor-positive patients who do not tolerate or have no response to cytotoxic regimens may receive hormone therapy with tamoxifen or other agents, including aromatase inhibitors (anastrozole and letrozole) or leuprolide acetate, or megestrol acetate. Patients with a performance score ≥ 3 should be considered only for best supportive care. Recommendation 8.3 Maintenance therapy with PARP inhibitors: It is suggested in patients with relapse advanced high-grade EOC stage III/IV BRCA1/2 (positive, negative or unknown) who have received two or more lines of platinum-based chemotherapy and have achieved CR/PR, use olaparib, niraparib or rucaparib. Niraparib could be useful in BRCA 1/2 +/-/unknown patients, as rucaparib, however, the latter does not yet have approval from the regulatory office in Colombia. Conclusions: It is expected that the recommendations issued in this consensus will contribute to improving clinical care, oncological impact, and quality of life of these women.
Introducción y objetivo: el abordaje de pacientes con cáncer epitelial de ovario (CEO) de alto grado avanzado o metastásico ha ido evolucionando a través del tiempo con el advenimiento de nuevas terapias y estrategias multimodales. El objetivo de este consenso de expertos es generar recomendaciones nacionales para el perfilamiento y manejo del CEO de alto grado avanzado o metastásico, definido como estadios III y IV de la clasificación de la Federación Internacional de Ginecología y Obstetricia (FIGO) al momento del diagnóstico, a partir de la revisión de la literatura que incluyó guías de práctica clínica (GPC) internacionales basadas en la evidencia. Materiales y métodos: once panelistas (oncólogos y ginecólogos oncólogos) respondieron ocho preguntas sobre el perfilamiento y manejo del carcinoma epitelial de ovario avanzado o metastásico. Los panelistas fueron escogidos por su perfil académico e influencia en instituciones de salud nacionales. Para el desarrollo del consenso se utilizaron los lineamientos de la "Conferencia de consenso de procedimientos operativos estandarizados de ESMO". Se definió que el nivel de acuerdo para aceptar una recomendación debía ser ≥ 80%. El documento fue revisado por pares. Resultados: Se hacen 8 recomendaciones generales, presentadas en cinco dominios; algunas de ellas se subdividen en recomendaciones específicas. Tratamiento inicial Recomendación 1 1.1. Como terapia inicial de elección para pacientes con CEO de alto grado o metastásico se sugiere la cirugía de citorreducción primaria (Cpr) completa que, idealmente, debe realizarse en centros con experiencia, seguida de terapia adyuvante. 1.2. Se sugiere quimioterapia neoadyuvante seguida de cirugía de citorreducción de intervalo (Cint) en quienes sea improbable alcanzar una citorreducción completa en la Cpr, bien sea por enfermedad metastásica no resecable o que presenten criterios de irresecabilidad (imagenológicos, laparoscópicos o por laparotomía) que hayan sido definidos por un ginecólogo oncólogo. También en pacientes con un pobre estado funcional y comorbilidades de acuerdo con el criterio del equipo multidisciplinario (oncología clínica, ginecología oncológica, radiología, etc.). Recomendación 2. En pacientes con CEO de alto grado, en estadio III localmente avanzado o metastásico, que recibieron quimioterapia neoadyuvante y alcanzaron respuesta completa o parcial (citorreducción con residuo tumoral < 2,5 mm), se podría evaluar el uso de la quimioterapia intraperitoneal hipertérmica (Hyperthermic IntraPeritoneal Chemotherapy - HIPEC) como alternativa a la quimioterapia IV adyuvante estándar basada en platinos durante la Cint, previa discusión en junta multidisciplinaria, en un centro de experiencia en este tipo de pacientes. Uso de pruebas genéticas Recomendación 3. Al momento del diagnóstico, se sugiere ofrecer testeo molecular genético a toda paciente con CEO de alto grado avanzado o metastásico, independientemente de la historia familiar. Recomendación 4. Se sugiere ofrecer asesoramiento genético, por parte de personal calificado, a toda paciente con CEO de alto grado avanzado o metastásico a quien se le ordene un testeo genético. Recomendación 5. Se sugiere que a toda paciente con CEO de alto grado avanzado o metastásico se le realice panel germinal que incluya los genes de susceptibilidad al cáncer de mama 1/2 (BRCA 1/2) y los otros genes de susceptibilidad de acuerdo con los protocolos institucionales y la disponibilidad de paneles de testeo genético; si es negativo entonces se debería realizar testeo somático que incluya el estatus de deficiencia de la recombinación homóloga (homologous recombination deficiency - HRD), independientemente de la historia familiar. Terapia adyuvante Recomendación 6 6.1. Se sugiere que a toda paciente con CEO estadios III/IV avanzado o metastásico, con estatus de desempeño (performance score care - PSC) de 0-2 se le administre como tratamiento estándar quimioterapia intravenosa (IV) adyuvante dentro de las seis semanas posteriores a la Cpr. Se sugiere administrar paclitaxel/carboplatino. 6.2. Se sugiere utilizar quimioterapia estándar basada en platino más bevacizumab como adyuvancia en pacientes con enfermedad de alto riesgo (CEO estadios IV o III con citorreducción tumoral subóptima), continuando con bevacizumab como mantenimiento. No se recomienda el uso de bevacizumab como terapia de mantenimiento si no se incluyó en la primera línea de tratamiento. Se sugiere seguir los esquemas de los estudios Gynecologic Oncology Group Study (GOG-0218) e International Collaborative Ovarian Neoplasm (ICON7). 6.3. Se sugiere la quimioterapia combinada IV/intraperitoneal (IP) solo para pacientes seleccionadas, con una citorreducción óptima (lesiones residuales < 1 cm), en especial aquellas sin enfermedad residual (R0) y que sean evaluadas en junta multidisciplinaria. La quimioterapia combinada IV/IP no se considera como tratamiento estándar. 6.4. 6.4.1. Se sugiere utilizar inhibidores de poli(ADP-ribosa) polimerasa (PARP) tales como olaparib o niraparib como mantenimiento después de recibir una primera línea de quimioterapia en pacientes con CEO estadios III/IV BRCA1/2 positivo que recibieron quimioterapia basada en platino y obtuvieron respuesta completa/respuesta parcial (RC/RP). 6.4.2. Se sugiere utilizar olaparib solo o en combinación con bevacizumab o niraparib en pacientes con CEO estadios III/IV BRCA1/2 positivo que recibieron quimioterapia basada en platino más bevacizumab y obtuvieron RC/RP. 6.4.3. Se sugiere utilizar niraparib en pacientes con CEO estadio III/IV BRCA1/2 negativo o desconocido que recibieron quimioterapia basada en platino y obtuvieron RC/RP. 6.4.4. Se sugiere utilizar bevacizumab u olaparib más bevacizumab en pacientes con CEO estadios III/IV BRCA1/2 negativo o desconocido (HRD positivo) que recibieron quimioterapia basada en platino más bevacizumab y obtuvieron RC/RP. Tratamiento de la recaída de la enfermedad Recomendación 7. Se sugiere la realización de la cirugía de citorreducción secundaria (Csec), seguida de quimioterapia, a pacientes seleccionadas con CEO de alto grado avanzado o metastásico en primera recaída, platino-sensibles (intervalo libre de platinos ≥ 6 meses), puntuación Arbeitsgemeinschaft Gynäkologische Onkologie (AGO) positiva o Integrate model (I-Model) positivo (< 4,7), y con una potencial resección a R0, en centros con acceso a soporte quirúrgico y posoperatorio óptimo. Nota: el intervalo libre de tratamiento con platinos y la puntuación AGO solo se han desarrollado como predictores positivos de resección completa y no para excluir a las pacientes de la cirugía. Recomendación 8 8.1. Para pacientes con CEO de alto grado avanzado o metastásico en recaída platino-sensibles se sugiere: Quimioterapia combinada basada en platino: carboplatino/doxorrubicina liposomal o carboplatino/paclitaxel o carboplatino/ nab-paclitaxel o carboplatino/docetaxel o carboplatino/gemcitabina, por seis ciclos. Si no se tolera la terapia combinada, dar carboplatino o cisplatino solo. Quimioterapia combinada: carboplatino/gemcitabina o carboplatino/paclitaxel o carboplatino/doxorubicina liposomal, más bevacizumab, seguida de bevacizumab como mantenimiento (hasta progresión o toxicidad). 8.2. Para pacientes con CEO de alto grado avanzado o metastásico en recaída, platino-resistentes, se sugiere: Tratamiento secuencial con quimioterapia, preferiblemente con un agente único que no sea un platino (paclitaxel semanal o doxorrubicina liposomal pegilada o docetaxel o etopósido oral o gemcitabina o trabectidina o topotecan). El paclitaxel semanal o la doxorrubicina liposomal pegilada o el topotecan pueden ser administrados con o sin bevacizumab. Existen otros agentes que se consideran potencialmente act ivos (capecitabina, ciclofosfamida, ifosfamida, irinotecán, oxaliplatino, pemetrexed, vinorelbina, ciclofosfamida), que se podrían recomendar para líneas posteriores. Las pacientes con receptores hormonales positivos que no toleran o no tienen respuesta a los regímenes citotóxicos pueden recibir terapia hormonal con tamoxifeno u otros agentes, incluidos los inhibidores de la aromatasa (anastrozol y letrozol) o acetato de leuprolide o acetato de megestrol. Pacientes con PSC ≥ 3 deberían ser consideradas solo para el mejor cuidado de soporte. 8.3. Terapia de mantenimiento con inhibidores PARP. Para pacientes con CEO de alto grado avanzado o metastásico en recaída estadios III/IV BRCA1/2 (positivo, negativo o desconocido), que hayan recibido dos o más líneas de quimioterapia basada en platino y hayan alcanzado RC/RP, se sugiere utilizar olaparib, niraparib o rucaparib. El niraparib podría ser útil en pacientes BRCA 1/2 +/-/desconocido, al igual que el rucaparib, sin embargo, este último no tiene aún aprobación del ente regulador en Colombia. Conclusiones: se espera que las recomendaciones emitidas en este consenso contribuyan a mejorar la atención clínica, el impacto oncológico y la calidad de vida de estas mujeres.

Objective: The Cancer Genome Atlas research program (TCGA) developed the molecular classification for endometrial cancer with prognostic and therapeutic utility, which was replaced by the ProMisE (Proactive Molecular Risk Classifier for Endometrial Cancer) classification by consensus and international guidelines due to its high cost. This article aims to present national recommendations from an expert consensus that allows unification and implementation of the molecular classification for women with endometrial cancer nationwide, with a rational use of resources and technology. Methods: Consensus of 36 experts in clinical oncology, oncological gynecology, pathology, and genetics, with clinical practice in the national territory. The leader group performed a literature review and structuring of questions rated 1 to 9 points. A modified nominal group technique was used. There was a face-to-face meeting with master presentations, deliberative dialogue, and Google Forms (Google LLC, Mountain View, CA, USA) questionnaire voting with analysis and discussion of responses. The non-consensual responses led to a second round of voting. The final manuscript was finally prepared and revised. Results: Seven recommendations were formulated integrating the panelist responses based on evidence, but adjusted to the Colombian context and reality. Recommendation 1. The molecular classification is recommended in all the endometrial cancers using the immunohistochemistry markers as subrogated results from the molecular profile initially proposed in the TCGA classification. Recommendation 2. The sequential test strategy is recommended, starting with the immunohistochemistry markers (p53, MLH1, MSH 2, MSH6, PMS2) simultaneously in all the patients, defining to request POLE (DNA polymerase epsilon) (if available) according to the risk classification based on the surgical piece. Recommendation 3. It is recommended, that the gynecologist oncologist should be the one to request the POLE (if available) according to the final pathology report. This test must be requested for all endometrial cancers stage I-II, except in low risk (stage IA low grade endometrioid histology without linfovascular invasion normal p53) and, stages III-IV without residual disease, without affecting the request of subrogated immunohistochemistry molecular markers upon histology. The consensus proposes that the POLE is requested after the immunohistochemistry and according to the categories in the risk classification established by the 2020 ESGO/ESTRO/ESP guidelines. Recommendation 4. It is recommended to perform immunohistochemistry for hormonal receptors for all women with endometrial cancer and the HER2 in patients with p53abn, simultaneously with the others immunohistochemistry markers. Recommendation 5. It is recommended to perform the immunohistochemistry markers (p53, MLH1, MSH2, MSH6 y PMS2) in an initial endometrial biopsy or curettage when the specimen is adequate and available. In case the initial immunohistochemistry is inconclusive, or there are histological discrepancies between the initial and definitive pathology, it is recommended to repeat the molecular profile in the surgical pathology. The immunohistochemistry markers must be reported in the pathology report according to the CAP (College of American Pathologists) recommendations, independently of the type of sample. Recommendation 6. It is recommended to perform MLH1 promoter methylation testing in patients who exhibit loss of expression of MLH1 in immunohistochemistry whether it is accompanied or not with loss of expression of PMS2. All the patients with deficient MMR (mismatch repair), should be sent for genetic counseling to rule out Lynch syndrome. Recommendation 7. It is recommended to consider the molecular classification in addition to the classical histopathological criteria when making adjuvant judgments, as incorporated by the classification of prognostic groups of the 2020 ESGO/ESTRO/ESP guidelines. Conclusions: It is necessary to implement the molecular classification of endometrial cancer in clinical practice in accordance to the Colombian context, due to its prognostic and probably predictive value. This will enable the characterization of the Colombian population in order to offer individualized guided treatments. This is an academic and nonregulatory document.
Objetivos: el programa Cancer Genome Atlas Research (TCGA) desarrolló la clasificación molecular para cáncer endometrial con utilidad pronóstica y terapéutica, la cual ha sido reemplazada por consensos y guías internacionales por la clasificación ProMisE (Proactive Molecular Risk Classifier for Endometrial Cancer) debido a su alto costo. El objetivo de este artículo es presentar recomendaciones a nivel nacional derivadas de un consenso de expertos que permitan unificar e implementar la clasificación molecular para mujeres con cáncer endometrial, mediante un uso racional de recursos y tecnología. Materiales y métodos: consenso de 36 expertos en oncología clínica, ginecología oncológica, patología y genética con práctica clínica en el territorio nacional. El grupo líder realizó una revisión de la literatura y estructuración de preguntas calificadas de 1 a 9 puntos. Se utilizó la técnica de grupo nominal modificada. Se efectuaron reuniones presenciales con presentaciones magistrales, diálogo deliberativo y votación de cuestionario Google Forms (Google LLC, Mountain View, CA, USA) con análisis y discusión de respuestas. Las respuestas no consensuadas se llevaron a una segunda ronda de votación. Finalmente, se elaboró y revisó el manuscrito final. Resultados: se formularon siete recomendaciones integrando las respuestas de las panelistas basadas en evidencia, pero ajustadas al contexto y a la realidad colombiana. Recomendación 1. Se recomienda realizar la clasificación molecular en todos los carcinomas endometriales utilizando los marcadores de inmunohistoquímica como resultados subrogados del perfil molecular inicialmente propuesto en la clasificación del TCGA. Recomendación 2. Se recomienda la estrategia secuencial de testeo iniciando por los marcadores de inmunohistoquímica (p53, MLH1, MSH 2, MSH6, PMS2) simultáneamente en todas las pacientes, y definir la solicitud del POLE (polimerasa épsilon del DNA) (si se encuentra disponible) de forma diferida de acuerdo con la clasificación de riesgo basado en la pieza quirúrgica. Recomendación 3. Se recomienda que sea el ginecólogo oncólogo quien solicite el POLE (si se encuentra disponible) de acuerdo con el reporte de patología definitivo. Esta prueba se debe solicitar a todos los cánceres endometriales de estadio I-II, excepto los de bajo riesgo (estadio IA endometrioide de bajo grado sin invasión linfovascular p53 normal) y estadio III-IV sin enfermedad residual, sin afectar la solicitud de los marcadores moleculares subrogados por inmunohistoquímica de acuerdo con la histología. El consenso propone que la solicitud del POLE se realice posterior a la inmunohistoquímica y de acuerdo con la clasificación del riesgo según las categorías establecidas por la guía ESGO/ESTRO/ESP del 2020. Recomendación 4. Se recomienda realizar simultáneamente con los otros marcadores de inmunohistoquímica la prueba para receptores hormonales en todas las pacientes con cáncer endometrial y el HER2 en pacientes con p53abn. Recomendación 5. Se recomienda que los marcadores de inmunohistoquímica (p53, MLH1, MSH2, MSH6 y PMS2) se realicen en la biopsia/legrado endometrial inicial cuando la muestra es adecuada y está disponible. En caso de inmunohistoquímica inicial no concluyente, o discrepancias histológicas entre la patología inicial y definitiva, se recomienda repetir el perfil molecular en la patología quirúrgica. Los marcadores de inmunohistoquímica deben reportarse en el informe de patología de acuerdo con las recomendaciones del CAP (College of American Pathologists), independientemente del tipo de muestra. Recomendación 6. Se recomienda realizar estudio de metilación de promotor de MLH1 en pacientes con pérdida de expresión de MLH1 en la inmunohistoquímica, acompañado o no de pérdida de expresión de PMS2. Todas las pacientes con déficit de MMR (mismatch repair), deben ser enviadas a genética para descartar síndrome de Lynch. Recomendación 7. Se recomienda tener en cuenta la clasificación molecular, además de los criterios histopatológicos clásicos para la toma de decisiones de adyuvancia, tal como los incorpora la clasificación de los grupos pronósticos de la guía ESGO/ ESTRO/ESP del 2020. Conclusiones: es necesario implementar la clasificación molecular de cáncer de endometrio en la práctica clínica acorde al contexto colombiano, dado su valor pronóstico y posiblemente predictivo. Esto permitirá la caracterización de la población colombiana para ofrecer tratamientos guiados de manera individualizada. Se trata de un documento académico y no regulatorio.

OBJECTIVE: To compare the pelvic lymph node involvement and risk of recurrence in patients with human papillomavirus (HPV)-associated endocervical adenocarcinoma stage IA2-IB1 undergoing hysterectomy and/or trachelectomy plus lymphadenectomy, according to Silva's classification system. METHODS: A retrospective cohort study was performed in two Colombian cancer centers. The cases were classified according to the Silva classification system. Clinical, surgical, and histopathological variables were evaluated. Recurrence risk was analyzed by patterns A, B, or C. A logistic regression model was performed for tumor recurrence. The Kaplan-Meier method was used to estimate overall survival and disease-free survival (DFS). A weighted kappa was performed to determine the degree of concordance between pathologists. RESULTS: A total of 100 patients were identified, 33% pattern A, 29% pattern B, and 38% pattern C. The median follow-up time was 42.5 months. No evidence of lymph node involvement was found in patients classified as A and B, while in the C pattern was observed in 15.8% (n = 6) of cases (P < 0.01). There were 7% of cases with recurrent disease, of which 71.5% corresponded to type C pattern. Patients with Silva pattern B and C had 1.22- and 4.46-fold increased risk of relapse, respectively, compared with pattern A. The 5-year DFS values by group were 100%, 96.1%, and 80.3% for patterns A, B, and C, respectively. CONCLUSION: For patients with early-stage HPV-associated endocervical adenocarcinoma, the type C pattern presented more lymph node involvement and risk of recurrence compared to the A and B patterns. The concordance in diagnosis of different Silva's patterns by independents pathologists were good.

OBJECTIVE: This systematic review and meta-analysis aimed to assess the rate of sentinel lymph node (SLN) metastases in patients with a pre-operative diagnosis of atypical hyperplasia/endometrial intra-epithelial neoplasia and endometrial cancer in hysterectomy specimens. METHODS: A systematic literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist and the protocol was registered in PROSPERO (CRD42023416769). MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and Scopus databases were searched from inception until April 2023. The inclusion criteria were patients with a pre-operative diagnosis of atypical hyperplasia/endometrial intra-epithelial neoplasia undergoing hysterectomy who did or did not undergo SLN assessment. RESULTS: Four studies met the inclusion criteria. All studies were non-randomized studies with a total of 10 217 patients, 1044 in the SLN group and 9173 in the non-nodal assessment group. The unilateral and bilateral detection rate was 89% (I2=27.6%, 2 studies, 342 participants, 304 events) and 79% (I2=89.2%, 2 studies, 342 participants, 271 events), respectively. The rate of involved SLNs was 1.6% (I2=0%, 3 studies, 424 participants, 7 involved SLN) and 3.5% (I2=0%, 3 studies, 197 participants, 7 involved SLN) in patients with a pre-operative diagnosis of atypical hyperplasia/endometrial intra-epithelial neoplasia as the denominator and in those with endometrial cancer in the hysterectomy specimen, respectively. The cancer rate in the hysterectomy specimen was 45% (I2=72.8%, 3 studies, 503 participants, 224 events) and the most frequent endometrial cancer International Federation of Gynecology and Obstetrics 2009 stage was IA in 199 (89.2%) patients. The complication rate was similar between the groups. CONCLUSION: The rate of SLN metastases in patients with pre-operative atypical hyperplasia/endometrial intra-epithelial neoplasia is less than 2%, suggesting that routine SLN evaluation may not be necessary in this population.
RESUMO
BACKGROUND: The affective expression of sexual behaviour in individuals with Williams syndrome can lead to risky behaviours, especially if parents do not have information on how to provide sex education or support from specialised professionals. METHOD: The Attitudes to Sexuality Questionnaire for Individuals with Intellectual Disabilities was used to identify parental beliefs, attitudes and concerns about the sexuality and sex education of individuals with intellectual disabilities. The sample comprised 35 parents of individuals with Williams syndrome (mean age 12.8 years (SD = 4.5), 57.1% male). RESULTS: Parents believe in the possibility of marriage and sexual relationships for individuals with intellectual disability when they are older and agree with sexual reproduction in adulthood. Parents consider that sex education, in addition to parental guidance, should be provided by professionals. CONCLUSIONS: This data highlights the need for parents to have clear guidelines on interventions in respect of the sexuality of individuals with intellectual disability.
RESUMO
OBJECTIVE: The objective of this systematic review was to assess the oncologic outcomes of patients with International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IVB cervical cancer receiving definitive pelvic radiotherapy compared with systemic chemotherapy (with or without palliative pelvic radiotherapy). METHODS: This study was registered in PROSPERO (registration number CRD42022333433). A systematic literature review was conducted following the MOOSE checklist. MEDLINE (through Ovid), Embase, and Cochrane Central Register of Controlled Trials were searched from inception until August 2022. The inclusion criteria were patients with metastatic FIGO 2018 stage IVB cervical cancer, a histologic subtype of squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma that received definitive pelvic radiotherapy (≥45 Gy) as part of management compared with systemic chemotherapy with or without palliative (30 Gy) pelvic radiotherapy. Randomized controlled trials and observational studies with two arms of comparison were considered. RESULTS: The search identified 4653 articles; 26 studies were considered potentially eligible after removing duplicates, and 8 met the selection criteria. In total, 2424 patients were included. There were 1357 and 1067 patients in the definitive radiotherapy and chemotherapy groups, respectively. All included studies were retrospective cohort studies, and two were database population studies. The median overall survival reported in seven studies for the definitive radiotherapy arm versus systemic chemotherapy groups were 63.7 months versus 18.4 months (p<0.01), 14 months versus 16 months (p value not reported), 17.6 months versus 10.6 months (p<0.01), 32 months versus 24 months (p<0.01), 17.3 months versus 10 months (p<0.01), and 41.6 months versus 17.6 months (p<0.01), and not reached versus 19 months (p=0.13) respectively, favoring the groups that received definitive pelvic radiotherapy. The high clinical heterogeneity precluded the performance of meta-analysis, and all studies were at serious risk of bias. CONCLUSIONS: Definitive pelvic radiotherapy as part of treatment in patients with stage IVB cervical cancer may improve oncologic outcomes compared with systemic chemotherapy (with or without palliative radiotherapy); however, this is based on low-quality data. Prospective evaluation would be ideal before the adoption of this intervention in standard clinical practice.

Desórdenes sistémicos de la homeostasis mineral o fallas en la mineralización de la matriz extracelular pueden afectar tanto a las piezas dentarias como a su aparato de sostén, conduciendo al fracaso de los tratamientos odontológicos. Existe poca evidencia científica sobre modelos animales que permitan es-tudiar la respuesta de tejidos dentarios/paradenta-rios frente a este tipo de desórdenes. El objetivo del presente trabajo fue estudiar experimentalmente al-teraciones de la biomineralización inducidas por bis-fosfonatos en ratas Wistar. Para ello, 20 ratas Wistar hembras y machos (35±10 g) fueron tratados con 20 mg/kg de etidronato bisódico (EHBP) o solución fi-siológica (control) vía intraperitoneal 5 veces por se-mana durante 3 semanas. Luego de la eutanasia, se extrajeron las mandíbulas para su procesamiento y análisis histológico (H&E). Mediante microfotografías digitales se evaluó: área ósea/área total, espesor de ligamento periodontal, áreas de dentina y de cemen-to. Los resultados se analizaron estadísticamente mediante el test T de Student para comparaciones entre grupos y el test ANOVA de 2 vías para las com-paraciones intersexo. Los grupos EHBP presentaron mayor proporción de osteoide, dentina y cemento no mineralizados respecto a los controles, siendo más marcadas las diferencias en las hembras. Las hem-bras del grupo EHBP mostraron una disminución significativa en el espesor del ligamento periodontal respecto de los controles, aunque esta tendencia no se observó en machos. Los resultados del presente estudio demuestran que el EHBP, en la dosis y tiempo estudiados, altera los procesos de biomineralización tanto del tejido óseo como de los tejidos dentarios (AU)
Systemic disorders of mineral homeostasis or alterations in the mineralization of the extracellular matrix can affect both dental and supportive tissues, leading to the failure of dental treatments. There is a lack of scientific information about animal models that allow to study the response of dental/paradental tissues in this type of disorders. The aim of the present work was to study the biomineralization alterations induced by bisphosphonates in Wistar rats and to study the response of dental and paradental tissues. Twenty Wistar rats (35±10 g) were divided in control (females, males) and EHBP (females, males) groups. The EHBP group received 20 mg/kg of ethidronate bisodium intraperitoneally 5 times a week for 3 weeks, while the control group received saline solution. After euthanasia, mandibles were resected and processed histologically to obtained oriented sections for H&E staining. Photomicrographs were used to evaluate: Bone area/total area, periodontal ligament thickness, dentin and cement area. Results were statistically analyzed using the Student's T test for comparisons between groups and the 2-way ANOVA test for male and female comparisons. The EHBP groups showed a higher amount of non-mineralized osteoid, dentin and cement compared to control groups, being more evident in females. Females in the EHBP group showed a significant decrease in periodontal ligament thickness compared to controls, although this profile was not observed in males. The results of the present study demonstrate that EHBP, at the dose and time studied, alters the biomineralization processes of both bone and dental tissues (AU)

Cervical cancer is the fourth most common cancer in women worldwide. The preferred treatment for early stage cervical cancer is radical hysterectomy with pelvic lymph node assessment, and adjuvant therapy is suggested according to histopathological risk factors. A landmark study was published in 1999 that established 'intermediate risk' criteria for relapse, showing a benefit in recurrence free rate in patients that received pelvic radiotherapy. Furthermore, in the presence of parametrial, nodal, or vaginal margin involvement, another key study found that the addition of concurrent cisplatin based chemotherapy to radiation therapy improved progression free and overall survival for 'high risk' early cervical cancer. With the advancement in treatment modalities in surgery and radiotherapy, and the improved identification of prognostic histopathological factors, several authors have reconsidered the role of adjuvant therapy after radical hysterectomy in the presence of intermediate risk criteria. Here we review the literature on the evolution of adjuvant therapy for intermediate risk factors.

OBJECTIVE: The objective of this systematic review was to assess the incidence of lymph node metastasis in patients with clinically presumed early-stage low-grade serous ovarian cancer that underwent primary surgical treatment. METHODS: This study was registered in PROSPERO (CRD42022308923). A systematic literature review was conducted following the Meta-analyses Of Observational Studies in Epidemiology (MOOSE) checklist. PubMed/MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Ovid, and Scopus databases were searched since inception and up to March 2022. The inclusion criteria were: pathological confirmation of low-grade serous ovarian cancer (clinically presumed FIGO 2014 stages I-IIA at time of surgery) that underwent primary surgical treatment, including pelvic and/or para-aortic lymph node dissection. RESULTS: The search identified 3763 articles; 59 were considered potentially eligible after removing duplicates, and eight studies finally met the selection criteria. In total, 35 of 277 (12.6%) patients had lymph node metastasis, and only four studies reported upstaging due to lymph node metastasis in 16 of 153 (10.5%) patients. None of the eight studies included reported the rate of complications or complications specifically for the subgroup of patients with early-stage low-grade tumors. CONCLUSION: In patients with early-stage low-grade serous ovarian cancer, lymph node assessment should be discussed when counseling for primary surgical staging.
RESUMO
OBJECTIVE: The objective of this systematic review was to assess the oncologic and fertility outcomes of patients with cervix-confined cancer >4 cm who underwent neo-adjuvant chemotherapy followed by fertility-sparing surgery. METHODS: This study was registered in PROSPERO (registration number CRD42021254816). PubMed/MEDLINE, ClinicalTrials, EMBASE, Cochrane Central Register of Controlled Trials, SCOPUS, and OVID databases were searched from inception to July 2021. The included patients were those with cancer confined to the cervix and tumor diameter >4 cm (International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IB3) with squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma who underwent intra-venous neo-adjuvant chemotherapy followed by successful fertility-sparing surgery. RESULTS: The initial search identified 2990 articles. A total of 40 patients from 11 studies had attempted fertility preservation surgery (conization, simple or radical trachelectomy) and in 26 patients (65%) it was successful. All patients received platinum-based chemotherapy. A complete pathological response occurred in 56% of patients and two patients (7.7%) had a recurrence. The 4.5-year disease-free survival was 92.3% and the 4.5-year overall survival rate was 100%. Of six patients who tried to conceive, four (67%) achieved at least one pregnancy and three of the five pregnancies (60%) were pre-term deliveries (all after radical trachelectomy). All patients with recurrence received cisplatin and ifosfamide instead of cisplatin and paclitaxel, underwent non-radical surgery, and had residual disease in the final specimen. CONCLUSIONS: Evidence for fertility-sparing surgery after neo-adjuvant chemotherapy in patients with cervical cancer and tumors >4 cm is limited, and this approach should be considered as an experimental intervention. As the use of non-radical surgery could be a risk factor, if neo-adjuvant chemotherapy is used, patients should undergo fertility-sparing radical surgery.

OBJECTIVE: The circumflex iliac nodes distal to the external iliac nodes are frequently removed when bilateral pelvic lymphadenectomy is performed in patients with cervical cancer. The objective of this systematic review was to assess the incidence of metastasis in the circumflex iliac nodes in patients with cervical cancer. METHODS: PubMed/Medline, ClinicalTrials, Embase, Cochrane Central Register of Controlled Trials, Scopus, and Ovid databases were searched from inception to May 2021. We included articles published in English language reporting all types of studies, except for case reports and commentaries. Abstracts and unpublished studies were excluded. The inclusion criteria were diagnosis of cervical cancer, FIGO 2009 stages IA-IIB, squamous cell carcinoma, adenocarcinoma or adenosquamous carcinoma, and primary surgery including pelvic lymph node dissection. RESULTS: A total of 3037 articles were identified. Overall, 1165 eligible patients from four studies were included in the analysis. A total of 696 (59.7%) patients had early-stage disease (FIGO 2009 stages IA, IB1, IIA1). The median number of extracted circumflex iliac nodes, which was reported in two studies, was one (range not reported) and three (range 1-13). The positive lymph node rate for the entire population and circumflex iliac node involvement were 26.9% and 3.1%, respectively. Isolated metastases were reported for 904 patients (three studies) and in one patient nodal spread was detected (0.11%). CONCLUSION: The rate of isolated metastases in circumflex iliac nodes is small and excision of these lymph nodes as part of routine lymphadenectomy should be avoided.

RESUMEN El envejecimiento poblacional es un tema de gran importancia por su crecimiento rápido y progresivo en los últimos años. Así mismo, con el aumento de la edad crece el grado de dependencia funcional, por consiguiente, mayor probabilidad de maltrato en el adulto mayor; convirtiéndose en un problema social y de salud pública a nivel mundial. El objetivo de este artículo es dar a conocer la importancia del abuso en el adulto mayor, sospecha y reconocimiento oportuno del mismo para realizar un abordaje integral desde la atención primaria. Se realizó una revisión narrativa que incluyó revisiones sistemáticas, revisiones de la literatura, reportes de caso y otros elementos, como noticias locales en Colombia, entre 2015 a 2019. No existe consenso alguno de la definición exacta, sin embargo, la más aceptada es la propuesta por la Organización Mundial de la Salud y la Organización de los Estados Americanos. Se han identificado factores de riesgo individuales, relacionales, socioculturales y comunitarios asociados a la perpetuación de este. Su clasificación está basada en dos grandes grupos: maltrato directo e indirecto. Existen diferentes herramientas de tamización de maltrato en el adulto mayor, dentro de estas la más utilizada es el Elder Abuse Suspicion Index (EASI), y estrategias que ayudan al médico de atención primaria al reconocimiento temprano y abordaje holístico del paciente. Tanto en Colombia como a nivel mundial, el Médico Familiar está en la capacidad de establecer un contacto más cercano con el anciano y su entorno generando un clima de confianza y empatía que permiten al profesional desde la atención primaria la detección temprana y prevención de cualquier tipo de abuso en esta población.
ABSTRACT Population ageing is an important issue due to its rapid and progressive growth in the last years. In addition, with increasing age, the degree of functional dependence increases, and with it, the likelihood of abuse in older adults, becoming a global social and public health problem. The aim of this article is to show the importance of abuse in older adults, and of early suspition and discovery, in order to carry out a comprehensive approach. This narrative review included systematic reviews, literature reviews, case reports, and other elements such as local news in Colombia, from 2015 to 2019. There is no consensus on the exact definition, however, the most accepted is the proposal of the World Health Organization and the Organization of American States. Several risk factors associated with its perpetuation have been identified, including relational, individual, sociocultural, and community factors. The abuse of older adults is classified into five groups: physical, emotional or psychological, economic or financial, sexual abuse, and neglect, the latter also includes abandonment. There are different screening tools for older adult abuse, among which the most used is the Elder Abuse Suspicion Index (EASI), and strategies that help the primary care physician to early recognition and carry out a holistic approach. Both in Colombia and worldwide, the Family Physician can establish closer contact with the older adults and their environment, generating a climate of trust and empathy that helps the primary care professional to early detection and prevention of any kind of abuse in this population.
RESUMO
Epigenetic changes have been shown to be associated with both aging process and aging-related diseases. There is evidence regarding the benefits of physical activity on the functionality, cognition, and quality of life of institutionalized older adults, however, the molecular mechanisms involved are not elucidated. The purpose of this pilot study was to investigate the effects of a multimodal exercise intervention on functional outcomes, cognitive performance, quality of life (QOL), epigenetic markers and brain-derived neurotrophic factor (BDNF) levels among institutionalized older adult individuals. Participants (n = 8) without dementia who were aged 73.38 ± 11.28 years and predominantly female (87.5%) were included in this quasi-experimental pilot study. A multimodal exercise protocol (cardiovascular capacity, strength, balance/agility and flexibility, perception and cognition) consisted of twice weekly sessions (60 minutes each) over 8 weeks. Balance (Berg Scale), mobility (Timed Up and Go test), functional capacity (Six-Minute Walk test), cognitive function (Mini-Mental State Examination) and QOL (the World Health Organization Quality of Life-BREF Scale questionnaire) were evaluated before and after the intervention. Blood sample (15 mL) was also collected before and after intervention for analysis of biomarkers global histone H3 acetylation and brain-derived neurotrophic factor levels. Significant improvements were observed in cognitive function, balance, mobility, functional capacity and QOL after the intervention. In addition, a tendency toward an increase in global histone H3 acetylation levels was observed, while brain-derived neurotrophic factor level remained unchanged. This study provided evidence that an 8-week multimodal exercise protocol has a significant effect on ameliorating functional outcomes and QOL in institutionalized older adult individuals. In addition, it was also able to promote cognitive improvement, which seems to be partially related to histone hyperacetylation status. The Ethics Research Committee of Centro Universitário Metodista-IPA, Brazil approved the current study on June 6, 2019 (approval No. 3.376.078).
RESUMO
BACKGROUND: Management of cervical cancer tumors >2 cm has been a subject of controversy, with management often considered as either up-front radical trachelectomy or neoadjuvant chemotherapy before fertility-sparing surgery. METHODS: A systematic literature review was conducted following the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) checklist. This study was registered in the International Prospective Register of Systematic Reviews (PROSPERO). We searched Medline through PubMed, EMBASE, Cochrane Central Register of Controlled Trials, SCOPUS, and OVID between January 1985 and December 2020. Eligibility criteria for selecting studies were English language, randomized controlled trials, and observational studies including information on fertility and oncologic outcomes. All titles were managed in EndNote X7. Risk of bias was evaluated using the Joanna Briggs Institute (JBI) critical appraisal checklist for observational studies. RESULTS: Twenty-three studies with 205 patients who received neoadjuvant chemotherapy were included. The majority of patients (92.2%, n=189) had stage IB FIGO 2009 cervical cancer. The preferred regimen used was cisplatin in combination with paclitaxel or ifosfamide (80%, n=164). One hundred and eighty patients (87.8%) underwent fertility-sparing surgery; radical vaginal trachelectomy, abdominal trachelectomy, conization, and simple trachelectomy were performed in 62 (34.4%), 49 (27.2%), 34 (18.9%), and 26 (14.4%) women, respectively. In nine patients (5%) the type of procedure was not specified. The follow-up time reported in all studies ranged between 6 and 69 months. In 112 women who sought a pregnancy after surgery, 84.8% (n=95) achieved a gestation.The global recurrence and death rates were 12.8% and 2.8%, respectively. CONCLUSION: Neoadjuvant chemotherapy followed by fertility-sparing surgery is a promising strategy that might allow fertility preservation in highly selected patients with cervical cancer with tumors >2 cm while providing acceptable oncologic outcomes. Results of prospective studies are required to validate its oncological safety. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42020203789.

OBJECTIVE: To describe oncologic and obstetric outcomes in patients diagnosed with cervical cancer during pregnancy who had a successful delivery after neoadjuvant chemotherapy. METHODS: A multicenter retrospective review was conducted in 12 institutions from six Latin American countries, between January 2007 and December 2018. Data collected included clinical characteristics, neoadjuvant chemotherapy agents, treatment, obstetric and oncologic outcomes. RESULTS: Thirty-three patients were included. Median age was 34 years (range 31-36). Twenty (60.6%) women were diagnosed at early stage (IB), and 13 (39.4%) with locally advanced stage (IIA-IIIB) according to FIGO 2009 classification. Carboplatin and paclitaxel was the most frequent combination used (60.6%). Partial and complete response rates were 27.3% and 9.1%, respectively. Median gestational age at delivery was 35 weeks (range 34-36). All patients had live births delivered by cesarean section. Obstetric pathology: pre-term labor, placenta percreta or intra-uterine growth restriction, was documented in seven patients (21.2%). Two (6.1%) neonates had low birth weight. Definitive treatment was primary chemo-radiation in 19 (57.6%) patients, radical hysterectomy in 11 (33.3%), abandoned radical hysterectomy with para-aortic lymphadenectomy and ovarian transposition in 1 patient (3.0%), and no further treatment in 2 (6.1%) patients. After a median follow-up of 16.3 months (range 2.0-36.9), 8 (26.7%) patients had recurrent disease. Of these, four (13.3%) died due to disease. CONCLUSION: Neoadjuvant chemotherapy may be offered to patients wishing to preserve an ongoing pregnancy in order to achieve fetal maturity. Long-term consequences of chemotherapy in the child are yet to be determined.

Resumen El cáncer de vulva representa el 2% al 5% de todos los cánceres ginecológicos a nivel mundial, dentro de los cuales, el más frecuente es el carcinoma escamocelular seguido por el melanoma. La cirugía es la piedra angular en el tratamiento de la neoplasia vulvar, y la evaluación del estado ganglionar es un poderoso predictor de supervivencia. La linfadenectomía inguinofemoral hace parte de las estrategias de tratamiento. La aproximación quirúrgica mínimamente invasiva por video endoscopia (VEIL) es una alternativa a la vía abierta que disminuye la morbilidad postoperatoria como dehiscencia de la herida quirúrgica, linfocele, linfedema, infección y deterioro psicosexual. A continuación, se describe la técnica quirúrgica VEIL como abordaje novedoso en Colombia para el manejo de la neoplasia vulvar.
Abstract Vulvar cancer represents 2% to 5% of all gynecological cancers worldwide, of which the most common is squamous cell carcinoma followed by melanoma. Surgery is the cornerstone in the treatment of vulvar neoplasia, and evaluation of lymph node status is a powerful predictor of survival. Inguinofemoral lymphadenectomy is part of the treatment strategies. The minimally invasive surgical approach by video endoscopy (VEIL) is an alternative to the open approach that reduces postoperative morbidity such as dehiscence of the surgical wound, lymphocele, lymphedema, infection, and psychosexual deterioration. The following describes the surgical technique of VEIL, as a novel approach in Colombia for the management of this cancer.
