RESUMO
Ischemia-reperfusion injury (IRI) during liver transplantation has been implicated in the recurrence of hepatocellular carcinoma (HCC). This systematic review aimed to evaluate interventions to reduce IRI during liver transplantation for HCC and their impact on oncologic outcomes. A comprehensive literature search retrieved four retrospective studies involving 938 HCC patients, utilising interventions such as post-operative prostaglandin administration, hypothermic machine perfusion, and normothermic machine perfusion. Overall, treated patients exhibited reduced post-operative hepatocellular injury and inflammation and significantly enhanced recurrence-free survival. Despite these promising results, the impact of these interventions on overall survival remains unclear. This underscores the imperative for further prospective research to comprehensively understand the efficacy of these interventions in HCC patients undergoing transplantation. The findings highlight the potential benefits of these strategies while emphasising the need for continued investigation into their overall impact.

ABSTRACT Purpose: Salvage robotic-assisted radical prostatectomy (S-RARP) has gained prominence in recent years for treating patients with cancer recurrence following non-surgical treatments of Prostate Cancer. We conducted a systematic literature review to evaluate the role and outcomes of S-RARP over the past decade. Materials and Methods: A systematic review was conducted, encompassing articles published between January 1st, 2013, and June 1st, 2023, on S-RARP outcomes. Articles were screened according to PRISMA guidelines, resulting in 33 selected studies. Data were extracted, including patient demographics, operative times, complications, functional outcomes, and oncological outcomes. Results: Among 1,630 patients from 33 studies, radiotherapy was the most common primary treatment (42%). Operative times ranged from 110 to 303 minutes, with estimated blood loss between 50 to 745 mL. Intraoperative complications occurred in 0 to 9% of cases, while postoperative complications ranged from 0 to 90% (Clavien 1-5). Continence rates varied (from 0 to 100%), and potency rates ranged from 0 to 66.7%. Positive surgical margins were reported up to 65.6%, and biochemical recurrence ranged from 0 to 57%. Conclusion: Salvage robotic-assisted radical prostatectomy in patients with cancer recurrence after previous prostate cancer treatment is safe and feasible. The literature is based on retrospective studies with inherent limitations describing low rates of intraoperative complications and small blood loss. However, potency and continence rates are largely reduced compared to the primary RARP series, despite the type of the primary treatment. Better-designed studies to assess the long-term outcomes and individually specify each primary therapy impact on the salvage treatment are still needed. Future articles should be more specific and provide more details regarding the previous therapies and S-RARP surgical techniques.
RESUMO
OBJECTIVE: Fear of cancer recurrence or progression (FCR) is considered one of the most common unmet needs among patients with cancer. This study sought to translate and evaluate the psychometric properties of the Fear of Cancer Recurrence scale (FCR4/7) and Fear of Cancer Recurrence Inventory-Short Form (FCRI-SF). METHODS: This study involved three phases: (1) translation and cultural adaptation of the FCR4/7 and FCRI-SF measures, (2) validity and reliability testing of the Portuguese version of these measures, and (3) examining patient's perceptions of these measures. Eligible patients were diagnosed with localized breast cancer, and patients with metastatic cancer. Descriptive analyses were collated, and psychometric analysis were conducted (confirmatory factor analysis). RESULTS: A total of 200 patients were recruited (100 patients with localized and 100 patients with metastatic cancer). A significant proportion of patients reported moderate to severe FCR (FCR7: 32.0% and FCRI-SF: 43.0%). Female gender, younger age and metastatic cancer were associated with higher levels of FCR. Psychometric analyses suggested that the Portuguese versions of the FCR4/7 and FCRI-SF were valid, unidimensional in nature, with acceptable reliability coefficients across all scales. In a sub-sample qualitative analysis (n = 75), most patients were satisfied with the relevance of both measures. CONCLUSION: Our findings suggest the Portuguese versions of the FCR4/7 and FCRI-SF are valid tools to assess FCR among patients with localized and metastatic cancer. Future research can now extend our understanding of FCR and assess this construct among Portuguese speaking patients, to guide the development of effective and targeted interventions for patients globally.

Resumen OBJETIVO: Identificar los factores asociados con la recidiva de cáncer de mama en pacientes con cirugía conservadora. MATERIALES Y MÉTODOS: Estudio observacional, de cohorte retrospectiva, efectuado a partir de expedientes de pacientes con cáncer de mama en estadios tempranos e intervenidas con cirugía conservadora. Parámetros de estudio: estadio, subtipo histológico, perfil de expresión de receptores hormonales, tiempo de seguimiento, recidiva y periodo libre de enfermedad. La tasa de recidiva, el periodo libre de enfermedad y la identificación de los factores asociados con recidiva se hicieron con análisis estadístico. RESULTADOS: Se estudiaron 53 pacientes con edad media de 51.0 ± 9.4 años. El subtipo histopatológico más frecuente fue el ductal en 49 de las 53 pacientes; en 48 de ellas los tumores fueron positivos para receptores de progesterona, en 7 de 53 para Her-2 y en 3 de 53 triple negativo. La tasa de recidiva de cáncer de mama fue de 13.2% (es decir: 7 de 53 pacientes). El tiempo libre de enfermedad en quienes recayeron fue de 30.6 ± 24.8 meses. En el análisis bivariado se asociaron significativamente con recidiva: los ganglios linfáticos positivos, la expresión de receptores de progesterona y de estrógenos, los tumores triple negativo y el tratamiento complementario con quimioterapia. En el análisis multivariado solo se asociaron con recidiva: tener un tumor triple negativo (OR = 51.8; IC95%: 4.9- 548.4; p = 0.001) y recibir quimioterapia (OR = 8.0; IC95%: 1.4-46.1; p = 0.020). CONCLUSION: Los factores asociados con la recidiva fueron los ganglios linfáticos positivos, la expresión de receptores de progesterona y de estrógenos, tumores triple negativo y recibir quimioterapia.
Abstract OBJECTIVE: To identify factors associated with breast cancer recurrence in patients undergoing conservative surgery. MATERIALS AND METHODS: Observational, retrospective cohort study conducted on the records of patients with early-stage breast cancer who underwent conservative surgery. Study parameters: stage, histologic subtype, hormone receptor expression profile, follow-up time, recurrence and disease-free period. Statistical analysis was performed to estimate recurrence rate and disease-free period and to identify factors associated with recurrence. RESULTS: Fifty-three patients with a mean age of 51.0 ± 9.4 years were evaluated. The most common histopathologic subtype was ductal in 49 of 53 patients; tumors were progesterone receptor positive in 48, Her-2 positive in 7 of 53, and triple negative in 3 of 53. The breast cancer recurrence rate was 13.2% (i.e., 7 of 53 patients). Disease-free time in those who relapsed was 30.6 ± 24.8 months. In bivariate analysis, positive lymph nodes, progesterone and estrogen receptor expression, triple-negative tumors, and adjuvant chemotherapy were significantly associated with recurrence. In multivariate analysis, only having a triple-negative tumor (OR = 51.8; 95%CI: 4.9-548.4; p = 0.001) and receiving chemotherapy (OR = 8.0; 95%CI: 1.4-58.4; p = 0.001) were associated with recurrence. CONCLUSION: Factors associated with recurrence were positive lymph nodes, expression of progesterone and estrogen receptors, triple-negative tumors, and receipt of chemotherapy.
RESUMO
Abstract Background Fear of cancer recurrence is one of the most distressing psychological consequences in cancer survivors and their informal primary caregivers (IPC). IPC of childhood cancer survivors (CCS) are often their mothers, which could intensify fear of cancer recurrence (FCR) and its impact on both IPC and CCS. However, the phenomenon has not been widely described in this specific population. Objective To summarize and analyze current evidence on the evaluation and management of FCR among IPC of CCS. Method A narrative review of studies included in four databases (PsycInfo, Medline, CINALH, and Web of Science) with no language or year of publication restrictions. Results Measures specifically developed to assess FCR among IPC of CCS comprising an interview and a questionnaire with initial psychometric evaluations and two short, online intervention programs based on cognitive-behavioral-contextual therapy were identified (ENGAGE and CASCAdE). Both have demonstrated acceptability in parents of CCS in high-income countries; preliminary evidence also exists of the effectivity of CASCAdE in reducing FCR. Discussion and conclusion Given the limitations of this area of psychological evaluation, the Fear of Cancer Recurrence Inventory, originally developed for adult cancer survivors, constitutes the most suitable tool for evaluating FCR among IPC of CCS. The CASCAdE program seems a promising intervention for IPC of CSS, although cultural adaptations, evaluations of its acceptability in low- and middle-income countries, and controlled studies in large samples are still required.
Resumen Antecedentes El miedo a la recurrencia del cáncer es una de las consecuencias psicológicas más angustiantes en los supervivientes y sus cuidadores primarios informales (CPI). Los CPI de supervivientes de cáncer infantil (SCI) a menudo son sus madres, lo que podría intensificar el miedo a la recurrencia (MR) y su impacto tanto a los CPI como a los SCI. Sin embargo, el fenómeno no se ha descrito ampliamente en esta población específica. Objetivo Resumir y analizar la evidencia actual sobre la evaluación y manejo del MR entre CPI de SCI. Método Se realizó una revisión narrativa de los estudios incluidos en cuatro bases de datos (PsycInfo, Medline, CINALH y Web of Science) sin restricciones de idioma o año de publicación. Resultados Se identificaron instrumentos desarrollados específicamente para evaluar MR entre CPI de SCI que comprenden una entrevista y un cuestionario, además de dos programas de intervención en línea basados en terapia cognitivo-conductual-contextual (ENAGE y CASCAdE). Ambos demostraron aceptabilidad en los padres de SCI en países de ingresos altos. También existe evidencia preliminar de la efectividad de CASCAdE en la disminución del MR. Discusión y conclusión Dadas las limitaciones de esta área de evaluación psicológica, el Inventario del Miedo a la Recurrencia del Cáncer, desarrollado originalmente para supervivientes adultos, constituye la herramienta más adecuada para evaluar MR en los CPI de SCI. El programa CASCAdE parece una intervención prometedora para CPI de SCI, aunque aún requiere adaptaciones culturales, evaluaciones de aceptabilidad en países de ingresos medio-bajos y estudios controlados con nuestras más grandes.
RESUMO
Diagnosis and treatment of pancreatic ductal adenocarcinoma (PA) remains a challenge in clinical practice. The aim of this study was to assess the role of microRNAs (miRNAs-21, -23a, -100, -107, -181c, -210) in plasma and tissue as possible biomarkers in the diagnosis of PA. Samples of plasma (PAp-n = 13), pancreatic tumors (PAt-n = 18), peritumoral regions (PPT-n = 9) were collected from patients during the surgical procedure. The control group consisted of samples from patients submitted to pancreatic surgery for trauma or cadaveric organs (PC-n = 7) and healthy volunteers donated blood (PCp-n = 6). The expression profile of microRNAs was measured in all groups using RT-PCR, serum CA19-9 levels were determined in PA and PC. In tissue samples, there was a difference in the expression of miRNAs-21, -210 (p < 0.05) across the PAt, PC and PPT groups. The PAp showed overexpression of miRNAs-181c, -210 (p < 0.05) when compared to PCp. The combination of miRNAs-21, -210 tissue expression and serum CA19-9 showed 100% accuracy in the diagnosis of PA, as well as miR-181c expression in the plasma (PApxPCp). The expression of microRNAs in plasma proved to be a promising tool for a noninvasive detection test for PA, as well as further studies will evaluate the utility of microRNAs expression as biomarkers for prognostic and response to therapy in PA.
RESUMO
Introduction: Surgery is the treatment of choice in locoregional thyroid neoplasia recurrence. The intense tissue healing process observed after surgery changes the neck anatomy, makes reoperation difficult, and interferes with surgical success. The use of the Radioguided Occult Lesion Localization (ROLL) technique has become a viable option to localize thyroid tumors. Objective: To analyze the use of the ROLL technique for the treatment of thyroid cancer recurrence with respect to its clinical, surgical and anatomopathological aspects. Methods: A descriptive cross-sectional study that analyzed 56 medical records and anatomopathological examinations of patients of both sexes who had thyroid neoplasms, underwent previous surgeries on this topography, and were submitted to the ROLL technique for recurrence removal from March 2011 to March 2019. Results: Most patients were women aged 46.05 years, on average. Papillary thyroid neoplasm was the most prevalent histological finding. In 100% of the cases, application of the ROLL technique identified and removed the lesions marked with suspicion for malignancy. Conclusion: Radioguided surgery has proved to be a very effective and safe tool to assist with lesion localization for the treatment of thyroid cancer recurrence. This technique has brought no additional side effects to patients, required minimal radiation and made surgery less invasive, reducing postoperative complication rates.
RESUMO
Abstract Background: The current evidence suggests that oncological surgery, which is a therapy used in the treatment of solid tumors, increases the risk of metastasis. In this regard, a wide range of tumor cells express Voltage-Gated Sodium Channels (VGSC), whose biological roles are not related to the generation of action potentials. In epithelial tumor cells, VGSC are part of cellular structures named invadopodia, involved in cell proliferation, migration, and metastasis. Recent studies showed that lidocaine could decrease cancer recurrence through its direct effects on tumor cells and immunomodulatory properties on the stress response. Objective: The aim of this narrative review is to highlight the role of VGSC in tumor cells, and to describe the potential antiproliferative effect of lidocaine during the pathogenesis of metastasis. Contents: A critical review of literature from April 2017 to April 2019 was performed. Articles found on PubMed (2000-2019) were considered. A free text and MeSH-lidocaine; voltage-gated sodium channels; tumor cells; invadopodia; surgical stress; cell proliferation; metastasis; cancer recurrence - for articles in English, Spanish and Portuguese language - was used. A total of 62 were selected. Conclusion: In animal studies, lidocaine acts by blocking VGSC and other receptors, decreasing migration, invasion, and metastasis. These studies need to be replicated in humans in the context of oncological surgery.
Resumo Justificativa: As evidências atuais sugerem que a cirurgia oncológica, usada no tratamento de tumores sólidos, aumenta o risco de metástase. Nesse sentido, uma ampla gama de células tumorais expressa Canais de Sódio Dependentes de Voltagem (CSDV), cujos papéis biológicos não estão relacionados à produção de potencial de ação. Nas células epiteliais tumorais, o CSDV é parte integrante de estruturas celulares denominadas invadópodes, que participam da proliferação, migração e metástase celular. Estudos recentes mostraram que a lidocaína pode diminuir a recorrência do câncer através de efeitos diretos nas células tumorais e de propriedades imunomoduladoras na resposta ao estresse. Objetivo: O objetivo desta revisão narrativa é analisar o papel do CSDV nas células tumorais e descrever o possível efeito antiproliferativo da lidocaína na patogênese das metástases. Conteúdo: Foi realizada uma revisão crítica da literatura de Abril de 2017 a Abril de 2019. Os artigos encontrados no PubMed (2000 − 2019) foram analisados. Pesquisamos textos de linguagem livre e descritores MeSH-lidocaína; canais de sódio dependentes de voltagem; células tumorais; invadópodes; estresse cirúrgico; proliferação celular; metástase; recorrência do câncer − em artigos publicados em inglês, espanhol e português. Foram selecionadas 62 publicações. Conclusão: Em estudos empregando animais, a lidocaína atua bloqueando o CSDV e outros receptores, diminuindo a migração, invasão e metástase. Esses estudos precisam ser replicados em humanos submetidos a cirurgia oncológica.

Tumour recurrence is currently a hot topic in liver transplantation. The basic mechanisms are increasingly discussed, and, for example, recurrence of hepatocellular carcinoma is often described in pre-injured donor livers, which frequently suffer from significant ischemia/reperfusion injury. This review article highlights the underlying mechanisms and describes the specific tissue milieu required to promote tumour recurrence after liver transplantation. We summarise the current literature in this field and show risk factors that contribute to a pro-tumour-recurrent environment. Finally, the potential role of new machine perfusion technology is discussed, including the most recent data, which demonstrate a protective effect of hypothermic oxygenated perfusion before liver transplantation.

INTRODUCTION: Locoregional recurrence of thyroid carcinoma has a negative impact on patient prognosis. In the current study, we retrospectively reviewed cases of thyroid bed lesions in the last 3 years, correlating cytologic diagnoses with clinical findings and, whenever available, final surgical diagnosis. MATERIALS AND METHODS: Cytologic results and needle wash thyroglobulin results from patients with fine-needle aspiration (FNA) of thyroid bed lesions were retrospectively collected from our electronic files. Additional retrieved data included sex, age at diagnosis, previous thyroidectomy diagnosis, time lapse since surgery, and corresponding surgical diagnosis (whenever available). RESULTS: A total of 91 cases from 72 patients (54 F, 18 M) were retrieved from the electronic files, with a median age of 49 years. Average interval between surgery and thyroid bed FNA was 5 years. Thyroglobulin levels were available for 60 (65.2%) cases. The average level was 276.2 ug/mL, with a range of <0.1 to 4720 ug/mL. Information on final surgical diagnosis was available for 31 samples. Complete agreement between final cytologic and histologic diagnoses was achieved in 28 of 31 (90.3%) of the cases, with 1 false negative and 2 false positives. Cytology sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 95.2%, 71.4%, 90.9%, 83.3%, and 89.1%, respectively. CONCLUSIONS: Ultrasound-guided FNA is an accurate and minimally invasive diagnostic method for suspicious thyroid bed lesions, with high sensitivity and positive predictive value.

BACKGROUND: Methylenetetrahyfrofolate reductase (MTHFR) is the key enzyme for one carbon and folate metabolism. Previous studies have drawn different conclusions about the relationship between the mutation of MTHFR and hepatocellular carcinoma (HCC) occurrence. MTHFR polymorphisms' influence on liver transplantation for HCC recurrence has yet not been reported. Aim of this study was to clarify the impact of MTHFR polymorphism on hepatocarcinogenesis and the prognosis of liver transplant recipient with HCC. METHODS: This study enrolled 244 HCC patients and 487 healthy individuals in Chinese Han population to analyze the influence of MTHFR polymorphism on HCC susceptibility first. Furthermore, this research choose another 100 donors' and 104 recipients' specimens to detect the association between polymorphism of MTHFR and post-transplant HCC recurrence. RESULT: rs1801131 polymorphism A to C was associated with the occurrence of HCC in Chinese Han population (p < 0.05), especially in age exceeding 50 years (p < 0.01). No association was observed with rs1801133 polymorphism and HCC occurrence. The mean tumor-free survival for recipients with donor liver graft rs1801133 C to T variants was shorter than CC type (12.63 ± 3.84 vs 22.43 ± 4.74 months, p < 0.05). Multivariate analysis revealed that Donor rs1801133 and Hangzhou criteria were two independent prognostic factors for tumor-free survival (p < 0.05). Neither donor rs1801131 polymorphism nor recipients' MTHFR polymorphisms was associated with HCC recurrence. CONCLUSION: This study demonstrated that MTHFR polymorphism was associated with HCC occurrence and post-transplant HCC recurrence. rs1801131 mutation A to C is a valuable molecular biomarker for predicting HCC occurrence in Chinese Han population. Donor MTHFR rs1801133 C to T polymorphism could present as a promising prognostic biomarkers for HCC recurrence in liver transplant recipients.

BACKGROUND: The benefit of surveillance after curative cystectomy in bladder cancer is unproven, but might be justified if detection of asymptomatic recurrence improves survival. Previous studies showing a benefit of surveillance might have been affected by lead-time or length-time bias. MATERIALS AND METHODS: We conducted a retrospective cohort study among 463 cystectomy patients at the University of Pennsylvania. Patients were followed according to a standardized protocol and classified according to asymptomatic or symptomatic recurrence detection. Primary outcome was all-cause mortality. Adjusted Cox regression models were used to assess the effect of mode of recurrence on survival from time of cystectomy (model 1) and time of recurrence (model 2) to account for lead and length time. RESULTS: One hundred ninety-seven patients (42.5%) recurred; 71 were asymptomatic (36.0%), 107 were symptomatic (54.3%), and 19 (9.6%) were unknown. Relative to patients with asymptomatic recurrence, patients with symptomatic recurrence had significantly increased risk of death (model 1: hazard ratio [HR], 1.67; 95% confidence interval [CI], 1.07-2.61; model 2: HR, 1.74, 95% CI, 1.13-2.69) and had lower 1-year overall survival from time of recurrence (29.37% vs. 55.66%). Symptomatic patients were diagnosed with recurrence a median of 1.7 months before asymptomatic patients, yet their median survival from recurrence was 8.2 months less. CONCLUSION: Symptomatic recurrence is associated with worse outcomes than asymptomatic recurrence, which cannot be explained by lead- or length-time bias. Similar methods to account for these biases should be considered in studies of cancer surveillance. Shortening surveillance intervals might allow for detection of more recurrences in an asymptomatic phase.

OBJECTIVES: To prospectively investigate the diagnostic accuracy and clinical consequences of power Doppler morphologic criteria and shear wave elastography (SWE) as complementary imaging methods for evaluation of suspected local breast cancer recurrence in the ipsilateral breast or chest wall. METHODS: Thirty-two breast masses with a suspicion of local breast cancer recurrence on B-mode ultrasonography underwent complementary power Doppler and SWE evaluations. Power Doppler morphologic criteria were classified as avascular, hypovascular, or hypervascular. Shear wave elastography was classified according to a 5-point scale (SWE score) and SWE maximum elasticity. Diagnostic accuracy was assessed by the sensitivity, specificity, and area under the curve. A decision curve analysis assessed clinical consequences of each method. The reference standard for diagnosis was defined as core needle or excisional biopsy. RESULTS: Histopathologic examinations revealed 9 (28.2%) benign and 23 (71.8%) malignant cases. Power Doppler ultrasonography (US) had sensitivity of 34.8% (95% confidence interval [CI], 6.6%-62.9%) and specificity of 45.4% (95% CI, 19.3%-71.5%). The SWE score (≥3) had sensitivity of 87.0% (95% CI, 66.4%-97.2%) and specificity of 44.4% (95% CI, 13.7%-78.8%). The SWE maximum elasticity (velocity > 6.5cm/s) had sensitivity of 87% (95% CI, 66.4%-97.2%) and specificity of 77.8% (95% CI, 40.0% to 97.2%). The areas under the curves for the SWE score and SWE maximum elasticity were 0.71 (95% CI, 0.53-0.87) and 0.82 (95% CI, 0.64-0.93), respectively (P = .32). CONCLUSIONS: Power Doppler US is unsuitable for discrimination between local breast cancer recurrence and fibrosis. Although the SWE score and SWE maximum elasticity can make this discrimination, the use of these methods to determine biopsy may lead to poorer clinical outcomes than the current practice of performing biopsies of all suspicious masses.

The normal physiologic stress mechanism, mediated by the sympathetic nervous system, causes a release of the neurotransmitters epinephrine and norepinephrine. Preclinical data have demonstrated an effect on tumor progression and metastasis via the sympathetic nervous system mediated primarily through the ß-adrenergic receptor (ß-AR) pathway. In vitro data have shown an increase in tumor growth, migration, tumor angiogenesis, and metastatic spread in breast cancer through activation of the ß-AR. Retrospective cohort studies on the clinical outcomes of ß-blockers in breast cancer outcomes showed no clear consensus. The purpose of this study was to perform a systematic review and meta-analysis of the effect of ß-blockers on breast cancer outcomes. A systematic review was performed using the Cochrane library and PubMed. Publications between the dates of January 2010 and December 2013 were identified. Available hazard ratios (HRs) were extracted for breast cancer recurrence, breast cancer death, and all-cause mortality and pooled using a random effects meta-analysis. A total of 7 studies contained results for at least 1 of the outcomes of breast cancer recurrence, breast cancer death, or all-cause mortality in breast cancer patients receiving ß-blockers. In the 5 studies that contained results for breast cancer recurrence, there was no statistically significant risk reduction (HR, 0.67; 95% confidence interval [CI], 0.39-1.13). Breast cancer death results were contained in 4 studies, which also suggested a significant reduction in risk (HR, 0.50; 95% CI, 0.32-0.80). Among the 4 studies that reported all-cause mortality, there was no significant effect of ß-blockers on risk (HR, 1.02; 95% CI, 0.75-1.37). Results of this systematic review and meta-analysis suggest that the use of ß-blockers significantly reduced risk of breast cancer death among women with breast cancer.

El tratamiento quirúrgico del cáncer de mama ha evolucionado, desde cirugías radicales que incluían la pared torácica hasta cirugías conservadoras de resección tumoral con margen oncológico seguro complementadas con radioterapia; estas se consideran alternativa a la cirugía radical. La supervivencia es similar en ambos procedimientos. Metodología: Estudio de cohorte retrospectivo que evaluó las características demográficas, patológicas y desenlaces clínicos, como recaída y mortalidad, en mujeres con cáncer invasivo, sometidas a cirugía conservadora entre 1998 y 2007 en el INC. Resultados: Se incluyeron 358 pacientes con edad promedio de 53 años y estados tumorales tempranos en su mayoría. Con mediana de seguimiento de cuatro anos se presentaron 40 recaídas entre locales, regionales y sistémicas con una tasa de recaída de 2,6 recaídas por 100 pacientes/año. Se presentó un mayor porcentaje de recaídas en estado clínico avanzado (p=0,022), tamaño tumoral mayor de 2 centímetros (p=0,02) y a mayor número de ganglios comprometidos en el vaciamiento axilar (p=0,004). La tasa de mortalidad fue 1,2 muertes por 100 pacientes/año. Los márgenes positivos se relacionaron con estado clínico avanzado (p=0,010) y las pacientes con márgenes positivos que recibieron manejo no quirúrgico presentaron un porcentaje mayor de recaída, comparado con las llevadas a cirugía (p=0,023). Esta diferencia se conservó al comparar manejo quirúrgico con no quirúrgico en márgenes positivos invasivos (p=0,037). Conclusiones: El estado clínico avanzado, se relacionó con márgenes positivos y recaída tumoral. El compromiso ganglionar axilar y el manejo no quirúrgico de los márgenes positivos determinaron un mayor porcentaje de recaída.
Surgical treatment for breast cancer has improved from radical surgery involving the chest wall, to conservative tumor resection surgery with oncologically safe margins. This latter, when supplemented with radiotherapy, is considered an alternative to radical surgery with similar survival for both procedures. Methodology: Retrospective observational study was performed to assess the clinical response in women older than 18 years with invasive cancer undergoing conservative surgery between 1998 and 2007. Results: A total 358 patients, with the majority in early tumor states were included for final revision. The mean age was 53 years. During a four year follow-up there were 40 local, regional and systemic relapses, with a progression rate of 2.6 relapses per 100 patients / year. There was a higher percentage of recurrence in advanced clinical status (P=.022), tumor size greater than 2 cm (P=.02), and greater number of lymph node involvement in the axillary clearance. Mortality rate was 1.2 deaths per 100 patients / year. Positive margins were associated with advanced clinical status (P=.010), and patients who received non-surgical management had a higher relapse rate compared with patients who had surgery (P=.023). This difference was maintained when comparing surgery with non-surgical management in invasive positive margins (P=.037). Conclusions: Advanced clinical stage was associated with positive margins and tumor relapse. Axillary lymph node involvement, and non-surgical management of surgical margins, resulted in a higher percentage of recurrence.
