RESUMEN

BACKGROUND: Advancements in the diagnosis, treatment, and surveillance of castration-resistant prostate cancer (CRPC) have progressed considerably, but a new biomarker that combines existing clinical and pathological data could be useful for a more precise diagnosis and prognosis. Some investigations have found that extracellular vesicle (EV)-derived miRNAs play crucial roles in various types of malignant tumors. The objective of this study was to explore EV miRNA and identify its biologic function as a biomarker for the diagnosis and prognosis of CRPC. METHODS: Plasma samples were collected from five healthy donors (Control, CT) and 17 CRPC patients, categorizing into two groups based on their endocrine treatment response: partial response (PR; n = 10) and progressive disease (PD; n = 7). Candidate extracellular vesicle (EV) miRNAs were identified using miRNA microarray and RT-qPCR. The biological functions of the selected miRNAs were evaluated using the MTT assay, wound healing assay, trans-well assay, and RNA sequencing in CRPC cells after transient miRNA expression. RESULTS: Microarray analysis revealed a significant downregulation of EV-miR-6880-5p in the PD samples compared to both CT and PR samples (p < 0.01). The expression of EV-miR-6880-5p in CRPC patients was decreased compared with that CT group (p = 0.0336) using RT-qPCR. In the PR group, EV-miR-6880-5p was increased at follow-up compared with the baseline (p = 0.2803), while in the PD group, it decreased at follow-up compared with the baseline samples (p = 0.4356). Furthermore, overexpression of miR-6880-5p hampered cell proliferation, migration, and invasion, downregulated pathways associated with tumor progression, and simultaneously upregulated pathways associated with cell growth and apoptosis in CRPC cells. CONCLUSIONS: EV-miR-6880-5p shows promise as a prognostic biomarker in patients with CRPC. Further, prospective validations are necessary to evaluate the potential of these candidate miRNAs.

RESUMEN

El conocimiento de la patología oral, y su correcto diagnóstico es fundamental en Odontología, puesto que un diagnóstico tardío, particularmente en casos de lesiones premalignas o malignas, pueden conducir a serias consecuencias para el paciente. El objetivo de este trabajo fue establecer la congruencia diagnóstica clínica - histopatológica de lesiones en cavidad oral en pacientes que asistieron a la Facultad de Odontología, Universidad de Costa Rica, y a quienes se les realizó biopsia de la lesión, durante el período 2016-2019. El estudio fue descriptivo y retrospectivo, basado en datos de reportes histopatológicos en la población mencionada, por presentar alguna lesión, de tejidos blandos o duros, en cavidad oral. La muestra estadística fue por conveniencia, no probabilística y no aleatoria. Las técnicas estadísticas utilizadas fueron descriptivas para el análisis de la información, el cual se basó en la distribución de frecuencias y cruce de variables. El procesamiento estadístico de los datos se diseñó en una base de datos creada en Excel. La muestra comprendió 160 reportes histopatológicos de los cuales se excluyeron 14. La edad promedio de los pacientes fue 42 años (rango 2 - 78 años). La proporción hombre: mujer correspondió 1:1.4, predominado el sexo femenino en 58,9 %. La congruencia del diagnóstico histopatológico con el diagnóstico clínico correspondió a 55,8 %. La congruencia de los diagnósticos demuestra el conocimiento del profesional en identificar la lesión clínicamente de forma correcta, lo que permite actuar en el momento preciso y confirmar la impresión clínica diagnóstica de una patología mediante el estudio histopatológico, el cual es el estándar oro. El problema radica en aquellos casos en que hay discrepancia diagnóstica, pues exige conocer los factores responsables de esta discrepancia, exige la búsqueda de soluciones y exige reforzar y redireccionar la formación académica del profesional y de los estudiantes para reconocer y describir estas lesiones.

Knowledge of oral pathology and its correct diagnosis is fundamental in Dentistry, since a late diagnosis, particularly in cases of premalignant or malignant lesions, can lead to serious consequences for the patient. The objective of this study was to establish the clinical- histopathological diagnostic consistency of lesions in the oral cavity in patients who attended the Faculty of Dentistry, Universidad de Costa Rica, and who underwent a biopsy of the lesion, during the period 2016-2019. The study was descriptive and retrospective, based on data from histopathological reports in the mentioned population, due to presenting some lesion, soft or hard tissue, in the oral cavity. The statistical sample was for convenience, non- probabilistic nor random. The statistical techniques used were descriptive for the analysis of the information, which was based on frequency distribution and crossing of variables. The statistical processing of the data was designed in a database created in Excel. The sample collects 160 histopathological reports, of which 14 were excluded. The average age of the patients was 42 years (range between 2 - 78 years old).The male:female ratio corresponded to 1:1.4, with a predominance of the female sex at 58.9 %.The congruence of the histopathological diagnosis with the clinical diagnosis corresponded to 55.8 %. Diagnostic consistency demonstrates knowledge of the professional in correctly identifying the lesion clinically, which allows acting at the precise moment and confirming the diagnostic clinical impression of the pathology via histopathological study which is the gold standard. The problem lies in those cases in which there is a diagnostic discrepancy, since it requires having knowledge of the underlying factors and therefore, requires searching for solutions, reinforcing and redirecting the academic training of professionals and students to recognize and describe these lesions.

RESUMEN

RESUMEN Objetivo: evaluar la sensibilidad y especificidad del test G8 en el tamizaje de adultos mayores con cáncer para la realización de la valoración geriátrica integral (VGI). Materiales y métodos: el presente estudio observacional y retrospectivo se realizó en el Servicio de Geriatría del Hospital Almenara de Lima, Perú. Se revisaron los informes de VGI en las historias clínicas electrónicos de adultos mayores (> 60 años) con cáncer, ambulatorios y hospitalizados, durante noviembre de 2022 y julio de 2023. Los pacientes se clasificaron según los criterios SIOG-1 (Sociedad Internacional de Oncología Geriátrica), formando dos grupos: pacientes aptos y pacientes no aptos o unfit (vulnerables + frágiles + muy enfermos). Del test G8 se estimó la sensibilidad, especificidad y valor predictivo positivo, área bajo la curva característica operativa del receptor (AUC). Resultados: ingresaron al estudio 201 pacientes, 91 mujeres (45,3%) y 110 (54,7%) varones, la media de la edad fue de 76,2 ± 7,4 años. Las neoplasias más frecuentes fueron colorrectal, estómago, próstata y vías biliares. La prevalencia de pacientes aptos y no aptos (unfit) fue del 23,4 y 76,6%, respectivamente. Cuando el puntaje de la prueba G8 fue ≤11, la sensibilidad, especificidad, valor predictivo positivo y AUC fueron 73,4% (intervalo de confianza al 95%: 65,7-80,2%), 91,5% (79,6%-97,6%), 96,6% (91,7-98,6%) y 89% (84-93%), respectivamente. Conclusiones: el test G8 con puntaje ≤11 tendría una alta sensibilidad y especificidad, para identificar adultos con cáncer vulnerables o frágiles, que podrían beneficiarse de la VGI.

ABSTRACT Objective: To evaluate sensitivity and specificity of the G8 test in screening older adults with cancer who may benefit from a Comprehensive Geriatric Assessment (CGA). Material and methods: This observational retrospective study was carried out in the Geriatrics Service of the Guillermo Almenara Hospital in Lima, Peru. CGA reports were reviewed in the electronic medical records of older adults (> 60 years) with cancer, both outpatients and inpatients, between November 2022 and July 2023. Patients were classified according to the SIOG-1 (International Society of Geriatric Oncology) criteria into two groups: fit and non-fit patients (vulnerable + frail + too sick). Sensitivity, specificity, and positive predictive value, area under the receiver operating characteristic curve (AUC), were estimated for the G8 test. Results: 201 patients entered the study, 91 women (45.3%) and 110 (54.7%) men; their mean age was 76.2 ± 7.4 years. The most frequent neoplasms were colorectal, stomach, prostate, and bile ducts. The prevalence of eligible and unfit patients was 23.4% and 76.6%, respectively. When the G8 test score was ≤11, sensitivity, specificity, positive predictive value, and AUC were 73.4% (95% Confidence Interval: 65.7- 80.2%), 91.5% (79.6%-97.6%), 96.6% (91.7-98.6%), and 89% (84-93%), respectively. Conclusions: The G8 test with a score ≤11 would have high sensitivity and specificity for identifying vulnerable or frail patients with cancer who could benefit from the CGA.

RESUMEN

Abstract In oncological services, questions on sexual orientation are not even addressed by professionals during appointments, which reinforces the invisibilization of lesbian women. This supports the assumption that all women assisted due to breast cancer have a hetero-oriented sexuality. This qualitative study aimed to analyze the meanings attributed by lesbian women with breast cancer and their partners to care practices and their health needs. Seven women participated, four of whom had been diagnosed with breast cancer and three were their intimate partners. Individual in-depth interviews were conducted, subjected to thematic analysis, interpreted from a gender perspective. Patients and partners reported receiving adequate care in health services and felt supported by professionals, but they also experienced episodes of disrespect and discrimination. The findings confirm the need to adopt inclusive health policies that are sensitive to the specificities of lesbian women.

Resumo Nos serviços oncológicos, perguntas sobre orientação sexual sequer são incluídas durante as consultas, reforçando a invisibilização de mulheres lésbicas. Isso acaba sustentando o pressuposto de que todas as mulheres assistidas em decorrência do câncer de mama têm sexualidade hetero-orientada. Este estudo qualitativo teve como objetivo analisar os significados atribuídos por mulheres lésbicas com câncer de mama e suas parceiras às práticas de cuidado e às suas necessidades de saúde. Participaram sete mulheres, sendo que quatro haviam recebido diagnóstico de câncer de mama e três eram suas parceiras íntimas. Foram realizadas entrevistas individuais, em profundidade, submetidas à análise temática, interpretadas na perspectiva de gênero. Pacientes e parceiras relataram que receberam cuidados adequados nos serviços de saúde e se sentiram apoiadas pelos profissionais, mas também vivenciaram episódios nos quais se sentiram desrespeitadas e discriminadas. Os achados endossam a necessidade de adoção de políticas de saúde inclusivas, sensíveis às especificidades das mulheres lésbicas.

Resumen En los servicios oncológicos, ni siquiera se incluyen preguntas sobre la orientación sexual durante las consultas, lo que refuerza la invisibilización de las mujeres lesbianas. Esto acaba sosteniendo la idea de que todas las mujeres tratadas por cáncer de mama tienen una sexualidad heteroorientada. Este estudio cualitativo pretendió analizar los significados atribuidos por las mujeres lesbianas con cáncer de mama y sus parejas a las prácticas asistenciales y a sus necesidades sanitarias. Participaron siete mujeres; cuatro habían sido diagnosticadas con cáncer de mama y tres eran sus parejas íntimas. Se realizaron entrevistas individuales en profundidad, y los datos se sometieron a un análisis temático, interpretado desde una perspectiva de género. Las pacientes y sus parejas informaron que recibieron una atención adecuada en los servicios sanitarios y se sintieron apoyadas por los profesionales, pero también vivieron episodios en los que se sintieron ofendidas y discriminadas. Los resultados avalan la necesidad de adoptar políticas sanitarias inclusivas y sensibles a las especificidades de las mujeres lesbianas.

RESUMEN

ABSTRACT Purpose: To evaluate the variables possibly related to actinic keratosis and malignant skin lesions on the eyelid. Methods: A prospective study of patients with suspected eyelid malignancy was conducted. The participants underwent a 2-mm punch biopsy at two opposite sites of the lesion for diagnosis, and the results were compared with those of the histopathological study of the surgical excised specimen. The patients with an actinic keratosis component were divided into two groups (actinic keratosis-associated malignancy and actinic keratosis alone), which were compared for the following variables: age, disease duration, largest diameter, tumor area, Fitzpatrick classification, sex, tumor site and margin involvement. A cluster analysis was also performed. Results: We analyzed 174 lesions, of which 50 had an actinic keratosis component. Actinic keratosis was associated with squamous cell carcinoma in 22% of the cases and to basal cell carcinoma in 38%, which shows that both neoplasms may have contiguous actinic keratosis. Statistical analysis revealed no significant difference among the variables. In a cluster analysis, four groups were identified with malignant lesions in the medial canthus with the largest mean diameter and area. All margin involvements on the lower eyelid were related to malignancy, which means that all cases with margin involvement had an almost 100% risk of malignancy. Conclusions: Larger actinic keratosis lesions in the medial canthus and lesions with margin involvement on the lower eyelid have a greater probability of malignant association.

RESUMO Objetivo: Avaliar as possíveis variáveis relacionadas à ceratose actínica e lesões malignas cutâneas nas pálpebras. Métodos: Estudo prospectivo de pacientes com lesões palpebrais suspeitas de malignidade. Os participantes foram submetidos à biopsia por trépano (punch) de 2-mm em dois pontos opostos da lesão como método diagnóstico e os resultados foram comparados com o estudo histopatológico da peça excisada cirurgicamente. Aqueles que apresentaram ceratose actínica como resultado foram divididos em dois grupos (ceratose actínica associada com malignidade e ceratose actínica isolada) e foram comparados de acordo com as variáveis: idade, tempo de doença, maior diâmetro, área do tumor, classificação de Fitzpatrick, gênero, localização e acometimento da margem palpebral. A análise de cluster também foi realizada. Resultados: Foram analisadas 174 lesões e 50 delas tinham ceratose actínica como componente do tumor. Ceratose actínica esteve associada ao Carcinoma Espinocelular em 22% dos casos e ao Carcinoma Basocelular em 38%, mostrando que ambos podem ter ceratose actínica adjacente. A análise estatística não encontrou diferença entre as variáveis. A análise de cluster identificou quatro grupos e mostrou que lesões malignas no canto medial tinham maiores diâmetro e área. Acometimento da margem na pálpebra inferior relacionou-se em 100% com malignidade, enquanto a ausência de acometimento da margem mostrou menor chance de malignidade. Conclusões: Lesões maiores de ceratose actínica no canto medial e lesões com acometimento da margem palpebral inferior têm maiores chances de associação com malignidade.

RESUMEN

Non-small cell lung cancer (NSCLC) is one of the oncological entities with the greatest evolution in molecular diagnosis due to the large number of diagnostic biomarkers and new treatments approved by international regulatory agencies. An accurate, early diagnosis using the least amount of tissue is the goal for the establishing and developing precision medicine for these patients. Rapid on-site evaluation (ROSE) provides cytological samples of optimal quantity and quality for a complete diagnosis of NSCLC. The usefulness of cytological samples has been demonstrated, not only for massive parallel sequencing but also for the quantification of the expression of programmed death-ligand 1 (PD-L1) and tumour mutational burden (TMB).Pre-analytical, analytical, and post-analytical recommendations are made for the management and appropriate use of cytological samples in order to obtain all the information necessary for the diagnosis and treatment of patients with NSCLC according to current quality parameters.(AU)

Abstract: Objective: Our aim was to understand cancer survivors' meanings of life after their cancer experience. Method: This was a biographical and qualitative study carried out from a naturalistic approach. We conducted in-depth interviews with five cancer survivors and analyzed the resulting content. Results: We found four categories: the stigma of cancer in survivorship; survivorship support networks; self-care in survivorship; and transcendence. The results gave us a greater understanding of survivors' needs and how they are being addressed by healthcare providers in Colombia. Conclusions: Cancer survivors shift towards a more holistic view of their health and transform the meaning of their life based on reflection and belief in God. Therefore, the nursing practice should focus on assisting them in these changes since healing.

RESUMEN

El Sarcoma Embrionario Indiferenciado, como tumor primario hepático es una patología que se presenta en la edad pediátrica, en adultos los casos son raros y representan aproximadamente el 0.2% de los tumores hepáticos primarios. Es una patología sumamente agresiva cuya presentación clínica es inespecífica destacándose el dolor en epigastrio e hipocondrio derecho y, en algunos casos, masa palpable en esta región del abdomen, así como síntomas de afectación sistémica como fiebre y pérdida de peso. El tratamiento curativo consiste en la resección quirúrgica del tumor y, en casos de irresecabilidad o afectación extrahepática, se justifica considerar radioquimioterapia paliativa y asociarla o no a cirugía. Pero a pesar de todo, el pronóstico es sombrío con una sobrevida menor a un año, por lo que el diagnóstico temprano es esencial. Se presenta el primer caso registrado de Sarcoma Embrionario Indiferenciado Hepático del Adulto en Paraguay

The primary hepatic sarcoma is a pathology characteristic of pediatric age, in adults are rare and account for approximately 0.2% of primary tumors. It is an extremely aggressive pathology whose clinical presentation is non-specific, highlighting the pain in epigastrium and right hypochondrium and in some cases, palpable mass in this region of the abdomen, as well as symptoms of systemic involvement such as fever and weight loss. The main treatment consists of surgical removal of the tumor and in cases of unresectableness or extrahepatic involvement it is justified to consider paliative radiochemotherapy and associate it or not with surgery. However, the prognosis is bleak with a survival of less than one year, so early diagnosis is essential. We present here the first registered case of Adult Primary Hepatic Sarcoma in Paraguay

RESUMEN

OBJECTIVE: To systematically analyze quantitative data about the effects of religion/spirituality and the well-being/quality of life of cancer patients. The second aim was to hypothesize a neurophysiological model of the association between religion/spirituality and the brain. METHODS: This study met the PRISMA Statement and was registered at PROSPERO database. Randomized and Controlled trials investigating religion/spirituality and well-being/quality of life of cancer patients were included. Based on neuroimaging and neurophysiology studies, a neuroanatomical model was developed to hypothesize the relationship between neuroscience and religion/spirituality. RESULTS: A large effect size was found on the improvement of well-being/quality of life (SMD = 3.90 [2.43-5.38], p < 0.01). Heterogeneity was high among studies (I2 = 98%, p < 0.01). Specific regions of the brain, such as the temporal lobes, amygdalae and hippocampus, regions from the limbic system, were hypothesized to take part in the religion/spirituality phenomena and the well-being/quality of life improvement. CONCLUSION: Religion/spirituality intervention, mainly the Islamic, promotes an improvement on wellbeing/quality of life of cancer patients.

OBJETIVO: Analisar sistematicamente dados quantitativos sobre os efeitos da religião/espiritualidade e o bem-estar/qualidade de vida de pacientes com câncer. O segundo objetivo foi levantar a hipótese de um modelo neurofisiológico da associação entre religião/espiritualidade e o cérebro. MÉTODOS: Este estudo seguiu as recomendações do PRISMA e foi registrado no PROSPERO. Estudos randomizados e controlados investigando religião/espiritualidade e o bem-estar/qualidade de vida de pacientes com câncer foram incluídos. Com base em estudos de neuroimagem e neurofisiologia, um modelo neuroanatômico foi desenvolvido para hipotetizar relações entre neurociência e religião/espiritualidade. RESULTADOS: Um tamanho de efeito grande foi encontrado na melhoria do bem-estar/qualidade de vida (SMD = 3,90 [2,43-5,38], p < 0,01). A heterogeneidade foi alta entre os estudos (I2 = 98%, p < 0,01). Regiões específicas do cérebro, como lobos temporais, amídalas e hipocampo, regiões do sistema límbico, foram hipotetizadas como participantes dos fenômenos religião/espiritualidade e melhoria do bem-estar/qualidade de vida. CONCLUSÃO: A intervenção religiosa/espiritual, principalmente islâmica, promove melhora no bem-estar/qualidade de vida em pacientes com câncer.

RESUMEN El cáncer de mama es el más frecuente en las mujeres y representa la segunda causa de muerte entre las féminas. Resulta fundamental la prevención mediante los programas de pesquizaje. El diagnóstico por imagen de este tumor ha evolucionado en los últimos años. En mamografía, se han incorporado las técnicas digitales, los aparatos de ultrasonidos son de mejor calidad y la resonancia magnética ha adquirido mayor protagonismo entre todos los algoritmos diagnósticos, no obstante, la mamografía sigue representando el examen de elección para la detección de este tipo de neoplasia en la población general. El objetivo del presente artículo es describir los aspectos imagenológicos de importancia que contribuyen al diagnóstico del cáncer de mama, para ello se realizó una revisión de la bibliografia, en diferentes bases de datos con el descriptor de estudios por imágenes en el cáncer de mama.

ABSTRACT Breast cancer is the most common in women and represents the second leading cause of death. Prevention through screening programs is essential. Imaging of this tumor has evolved in recent years. In mammography, digital techniques have been incorporated, ultrasound machines are of better quality and magnetic resonance imaging has acquired greater prominence among all diagnostic algorithms, however, mammography continues to represent the test of choice for the detection of this type of neoplasia in the general population. The aim of this article is to describe the important imaging aspects that contribute to the diagnosis of breast cancer, for this, a review of the literature was carried out in different databases with the descriptor of imaging studies in breast cancer.

RESUMEN

RESUMEN Fundamento: el mioblastoma de células granulares también conocido como tumor de Abrikossoff es una neoplasia benigna de rara frecuencia formada por células de aspecto granular. Objetivo: exponer aspectos clínicos del mioblastoma de células granulares. Presentación del caso: se reportó el caso de un paciente masculino de raza negra, 50 años de edad, que fue remitido de la Atención Primaria con impresión clínica de fibroma lingual, al examen bucal se observó lesión ovoide de 3 cm de diámetro en el dorso de la lengua, asintomática, firme, hipocoloreada, consistencia dura y bordes precisos. Se realizó exéresis mediante biopsia escisional. El diagnóstico histopatológico determinó mioblastoma de células granulares. Conclusiones: tanto las características clínicas como histológicas del tumor de células granulares son muy semejantes a otras neoplasias malignas que se asientan en la lengua como el carcinoma epidermoide por tanto su diagnóstico constituye un reto para el estomatólogo.

ABSTRACT Background: granular cell tumor known as Abrikossoff´s tumor is a benign neoplasm of rare incidence formed by cell of granular aspects. Objective: to expose clinical aspects of granular cell tumor. Case report: a clinical case is reported of a 50 years-old black male patient. He was remitted of Primary Health Service with diagnostic impression of tongue's fibroma, in the oral exam was detected an oval lesion of 3cm of diameter on dorsum of the tongue, asymptomatic, firm consistency, and well defined. The lesion was removed by excision biopsy. The histological-pathological study determined a granular cell tumor. Conclusions: both the clinical and histological characteristics of the granular cell tumor are very similar to other malignant neoplasm that settle on the tongue such as epidermoid cell carcinoma therefore its diagnosis constitutes a challenge for the dentistry.

RESUMEN

Gastric cancer is one of the most common malignancy in China. Most of the patients of gastric cancer treated clinically are in advanced stage. In the past years, with the progress of anti-cancer drug therapy, after the comprehensive treatment based on drugs therapy of inoperative stage IV gastric cancer, some cases can reduce the tumor stage and get the opportunity of radical operation. Some of the patients who underwent surgical treatment can get the chance of long-term survival. The results of REGATTA trial confirmed that palliative surgery plus chemotherapy could not improve the long-term survival of patients with stage IV gastric cancer. Neoadjuvant intraperitoneal plus intravenous chemotherapy can reduce the tumor stage of some cases of stage IV gastric cancer with peritoneal metastasis and receive surgical treatment, so as to gain the chance of long-term survival. Regimen of intraperitoneal hyperthermia chemotherapy combined with PHOENIX trial is expected to improve the conversion operation rate of gastric cancer with peritoneal metastasis. Paclitaxel-based three-drug chemotherapy can reduce the tumor stage of some inoperable advanced gastric cancer and obtain the opportunity of radical operation, improving the disease-free survival rate and overall survival rate of patients, thus has become the cornerstone of conversion therapy for stage IV gastric cancer. Antiangiogenic targeted drug apatinib combined with paclitaxel is safe and reliable, and can be used as an alternative for the conversion therapy of stage IV gastric cancer, which provides a new idea for cytotoxic drugs combined with targeted drugs.

RESUMEN

Gastric cancer is one of the most common malignancy in China. Most of the patients of gastric cancer treated clinically are in advanced stage. In the past years, with the progress of anti-cancer drug therapy, after the comprehensive treatment based on drugs therapy of inoperative stage IV gastric cancer, some cases can reduce the tumor stage and get the opportunity of radical operation. Some of the patients who underwent surgical treatment can get the chance of long-term survival. The results of REGATTA trial confirmed that palliative surgery plus chemotherapy could not improve the long-term survival of patients with stage IV gastric cancer. Neoadjuvant intraperitoneal plus intravenous chemotherapy can reduce the tumor stage of some cases of stage IV gastric cancer with peritoneal metastasis and receive surgical treatment, so as to gain the chance of long-term survival. Regimen of intraperitoneal hyperthermia chemotherapy combined with PHOENIX trial is expected to improve the conversion operation rate of gastric cancer with peritoneal metastasis. Paclitaxel-based three-drug chemotherapy can reduce the tumor stage of some inoperable advanced gastric cancer and obtain the opportunity of radical operation, improving the disease-free survival rate and overall survival rate of patients, thus has become the cornerstone of conversion therapy for stage IV gastric cancer. Antiangiogenic targeted drug apatinib combined with paclitaxel is safe and reliable, and can be used as an alternative for the conversion therapy of stage IV gastric cancer, which provides a new idea for cytotoxic drugs combined with targeted drugs. In the era of immunotherapy, the combined application and first-line application of immunosuppressive drugs has become a clinical consensus. For advanced Her-2 positive esophagogastric junction adenocarcinoma cases, the successful exploration of the four-drug combination of chemotherapy+ anti-Her-2 targeted drugs+ anti-PD1 monoclonal antibody combined with the first-line therapy has opened up a new era of transformational therapy for stage IV gastric cancer. Gastric cancer is a malignant tumor with high heterogeneity, the classification of stage IV gastric cancer represented by Yoshida classification is based on imaging, and a more reasonable classification method should be developed in combination with gene detection in the future. Based on this, an individualized and accurate conversion therapy plan is formulated, so as to effectively improve the long-term survival of patients with stage IV gastric cancer.

RESUMEN

ABSTRACT: The aim of this study was to verify the applicability and accuracy of B-mode ultrasonography in detecting malignancy in dog cutaneous neoplasms. Forty-two neoplasms (12 benign and 30 malignant) of mesenchymal, round cells, epithelial and melanocytic origins from 24 dogs of different breeds and ages were included. The ultrasound evaluation was performed with a linear multi-frequency transducer (7.0 to 12MHz), with frequency dependent on the mass dimension. Ultrasonographic characteristics of echogenicity (hypo/hyperechogenic), echotexture (homogeneous/heterogeneous), regularity, invasiveness in adjacent tissues were classified. Dimensions were also measured to calculate the depth/width ratio. Neoplasms were classified as malignant or benign after cytological and/or histopathological analysis and the results were associated with ultrasound characteristics. There was a significant association (P 0.05) between malignancy and echogenicity, echotexture and invasiveness in adjacent tissues, so that 84.6% of hypoechogenic neoplasms, 76.9% of heterogeneous masses and 88.2% of invasive neoplasms were classified as malignant. However, for all these associations, moderate predictive values were obtained, which may be due to the small experimental number included in this study. Therefore, although it has been observed that hypoechogenic, heterogeneous and invasive neoplasms were more prone to malignancy, these findings should be used with caution until new studies are developed with a greater number and variety of cutaneous neoplasms in dogs.

RESUMO: O objetivo deste estudo foi verificar a aplicabilidade e acurácia da ultrassonografia modo-B na detecção de malignidade em neoplasmas cutâneos de cães. Foram incluídos 42 neoplasmas (12 benignos e 30 malignos) de origens mesenquimal, células redondas, epitelial e melanocítica provenientes de 24 cães de diferentes raças e idades. O exame ultrassonográfico foi realizado com transdutor linear multifrequencial (7.0 a 12MHz), com frequência dependente da dimensão da massa. Foram classificadas características ultrassonográficas de ecogenicidade (hipo/hiperecogênicos), ecotextura (homogêneos/heterogêneos), regularidade, invasividade em tecidos adjacentes. As dimensões foram mensuradas para cálculo da razão profundidade/largura. Os neoplasmas foram classificados como malignos ou benignos após análise cito e/ou histopatológica e os resultados foram associados com as características ultrassonográficas. Verificou-se associação significativa (P 0.05) entre malignidade e ecogenicidade, ecotextura e invasividade em tecidos adjacentes, de forma que 84.6% dos neoplasmas hipoecogênicos, 76.9% das massas heterogêneas e 88.2% dos neoplasmas invasivos foram classificados como malignos. Entretanto, para todas essas associações, foram obtidos valores preditivos moderados, que podem ser decorrentes do baixo número experimental incluso neste estudo. Sendo assim, embora tenha sido observado que os neoplasmas hipoecogênicos, heterogêneos e invasivos tiveram maior propensão à malignidade, esses achados devem ser utilizados com cautela até novos trabalhos sejam desenvolvidos com maior número e variedade de neoplasmas cutâneos de cães.

RESUMEN

Abstract The Common Sense Model refers to the association between disease perception and health behaviors. This study aimed to analyze the psychometric properties of the Revised Illness Perception Questionnaire for Healthy People - (IPQ-RH) in healthy women about breast cancer. A total of 321 women participated, with a mean age of 55.72 years old (SD = 10.75), users of Basic Health Units. Confirmatory factor analyzes (CFAs) were carried out and the McDonald's Omega and Cronbach's alpha coefficients were calculated. The results of the CFAs confirmed the structure of seven factors for the IPQ-RH (CFI = .92; TLI = .91; RMSEA = .03; SRMR = .06) and of two factors for the subscale of causes of the disease (CFI = .97; TLI = .97; RMSEA = .00; SRMR = .05). The instrument's reliability was, in general, satisfactory. The IPQ-RH has appropriate psychometric properties to investigate the illness perception in healthy women.

Resumo O Modelo do Senso Comum aponta para a associação entre a percepção da doença e comportamentos em saúde. Este estudo teve por objetivo examinar as propriedades psicométricas do Questionário de Percepção da Doença para Pessoas Saudáveis - Revisado (IPQ-RH) em mulheres saudáveis sobre o câncer de mama. Participaram 321 mulheres, com idade média de 55,72 anos (DP = 10,75), usuárias de Unidades Básicas de Saúde. Foram realizadas análises fatoriais confirmatórias (AFCs) e calculados os coeficientes Ômega de McDonald e alpha de Cronbach. Os resultados das AFCs confirmaram a estrutura de sete fatores para o IPQ-RH (CFI = .92; TLI = .91; RMSEA = .03; SRMR = .06) e de dois fatores para a subescala de causas da doença (CFI = .97; TLI = .97; RMSEA = .00; SRMR = .05). A fidedignidade do instrumento foi, em geral, satisfatória. O IPQ-RH apresenta propriedades psicométricas adequadas para investigar a percepção da doença em mulheres saudáveis.
