1. Tissue Factor Expression in Colorectal Adenocarcinoma: Association with Angiogenesis and Clinical and Pathological Aspects
Abstract Introduction Tissue factor (TF) expression has been described in various neoplasms and was correlated with angiogenesis and metastases. Objectives To describe TF expression in colorectal cancers, correlating it with microvessel density and clinical and pathological variables. Methods Immunohistochemistry was used to determine TF expression and

2. IS SUPERFICIAL COLORECTAL LESIONS WITH LOW AND HIGH GRADES INTRAEPITHELIAL NEOPLASMS MORE PREVALENT IN OLDER ABOVE 65 YEARS?
RESUMO Racional: O câncer colorretal tem maior incidência no reto e sigmoide. Porém, com a ampliação do diagnóstico das lesões superficiais do cólon e reto tem-se aumentado o interesse por elas no diagnóstico e no papel que elas representam na carcinogênese colorretal. Objetivo: Verificar o comportamento das lesões superficiais do cólon e reto,

3. Outcomes of Elderly Patients Undergoing Emergency Surgery for Complicated Colorectal Cancer: A Retrospective Cohort Study
OBJECTIVE: Colorectal cancer is one of the most frequent types of malignant neoplasms. Age is a risk factor for this disease, with 75% of cases diagnosed in patients older than 65 years. Complications such as obstruction, hemorrhage, and perforation are present in more than one-third of cases and require emergency treatment. We aim to analyze the profile of

4. Colorectal robotic surgery: INCA's experience
RESUMO Introdução: A cirurgia minimamente invasiva revolucionou o tratamento cirúrgico no manejo das neoplasias colorretais, reduzindo a morbidade e mortalidade, a hospitalização, o tempo de inatividade e minimizando os custos, além de fornecer resultados oncológicos adequados quando comparada à abordagem convencional. A cirurgia robótica, com a Pl

5. Mortalidade por câncer em populações indígenas no Estado do Acre, Brasil
O objetivo do estudo foi estimar a mortalidade por câncer em povos indígenas no Estado do Acre, Brasil. Trata-se de estudo observacional descritivo, com base no banco nominal do SIM (Sistema de Informações sobre Mortalidade), referente ao período de 1º de janeiro de 2000 a 31 de dezembro de 2012. Foi analisada a distribuição de frequência de óbitos

6. Clinical stage and histological type of the most common carcinomas diagnosed in young adults in a reference cancer hospital
OBJECTIVES: Cancer in young adults represents a great challenge, both biologically and socially, and understanding the unique characteristics of neoplasms in this age group is important to improving care. We aimed to evaluate the most common carcinomas and their characteristics, such as histological type and clinical stage, in young adults in the largest ca

7. Absence of TERT promoter mutations in colorectal precursor lesions and cancer
Abstract Hotspot mutations (c.-124bp G > A and c.-146bp G > A) in the promoter region of the TERT gene have been recently described in several types of solid tumors, including glioma, bladder, thyroid, liver and skin neoplasms. However, knowledge with respect to colorectal precursor lesions and cancer is scarce. In the present study we aimed to determine the

8. Syndrome in question
AbstractMuir-Torre syndrome is a rare genodermatosis characterized by the occurrence of at least one sebaceous tumor associated with visceral neoplasia, but with no predisposing factors. The sebaceous neoplasm may appear before, during or after the diagnosis of colorectal cancer. As it is regarded as a subtype of nonpolyposis hereditary colorectal cancer, it

9. ImunoexpressÃo de metaloproteinases 2 e 14 e do inibidor TIMP-2 no cÃncer colorretal / Immunoexpression of metalloproteinases 2 and 14 and the inhibitor TIMP-2 in colorectal cancer
O cÃncer colorretal(CCR) Ã altamente prevalente nos paÃses mais ricos e industrializados. As metaloproteinases de matriz (MMPs) sÃo importantes enzimas que facilitam a invasÃo e disseminaÃÃo do tumor em vÃrios tipos de cÃncer, inclusive o colorretal. Os inibidores teciduais de metaloproteinases (TIMPs) sÃo os principais inativadores fisiolÃgicos d

10. Influence of genetic polymorphisms in metabolism of folic acid in susceptibility to sporadic colorectal adenocarcinoma / Influência de polimorfismos gênicos do metabolismo do ácido fólico na susceptibilidade ao adenocarcinoma colorretal esporádico = : Influence of genetic polymorphisms in metabolism of folic acid in susceptibility to sporadic colorectal adenocarcinoma
O desenvolvimento de câncer colorretal (CCR) é resultado de uma complexa interação de variáveis, incluindo elementos externos, como a exposição a agentes ambientais e dietéticos, e fatores internos, de natureza somática ou hereditária. Não está estabelecido se genótipos de polimorfismos de baixa penetrância em genes relacionados com o metabolis

11. Avaliação das margens cirúrgicas e do tipo de borda tumoral nas ressecções hepáticas por metástase de câncer colorretal e seu impacto na mortalidade e recidiva / Evaluation of surgical margins and the type of tumor growth pattern in colorectal liver metastases resection and its impact on mortality and recurrence
INTRODUCTION: Approximately 50% of patients with colorectal cancer have liver metastases and hepatectomy is the therapeutic procedure of choice. Surgical margin is an ever-recurring discussed prognostic factor, because there is no consensus of the minimum required distance between the metastatic nodule and the liver section line. Some authors reported surgic

12. Cultivation and identification of colon cancer stem cell-derived spheres from the Colo205 cell line
Our group established a method to culture spheres under serum-free culture condition. However, the biological characteristics and the tumorigenicity of spheres are unknown. Here, we demonstrate that sphere cells expressed high levels of the putative colorectal cancer stem cell markers CD133 and CD44. The CD133-positive rates were 13.27 ± 5.62, 52.71 ± 16.9
