1. Therapeutics in Radiation-induced Proctopathy: A Systematic Review
Abstract Malignant neoplasms are increasingly prevalent in the daily clinical practice. Up to 61% of patients with pelvic malignancies undergo pelvic radiotherapy in different doses, which may cause intestinal damage, and the rectum is the segment most frequently affected due to its fixed position in the pelvis. Currently, there are several strategies to min

2. Transanal minimally invasive surgery with single-port (TAMIS) for the management of rectal neoplasms: a pilot study
A microcirurgia endoscópica transanal (TEM) é usada desde a década de 80 para o tratamento de neoplasias retais selecionadas, com claros benefícios relacionados à mortalidade e morbidade, e com bons resultados oncológicos, em comparação à cirurgia radical e a ressecções locais convencionais. O custo alto de equipamento de TEM e a necessidade de um

3. Resultados da associação de braquiterapia de alta taxa de dose à teleterapia no câncer da próstata / Results of the association of high dose-rate brachytherapy with external beam irradiation in prostate cancer
INTRODUCTION: high dose-rate brachytherapy (HDR) for prostate cancer may be a nice treatment option for dose escalation as a boost, when associated to external beam irradiation, mainly if 3D conformal or more advanced technology is not available. PURPOSE: this study analyzes the results and toxicities of HDR brachytherapy boost prior to external beam radioth

4. Quality of life of patients with colon and rectal cancer / Qualidade de vida de pacientes com câncer de cólon e reto: revisão integrativa da literatura
Colon and rectal cancer affects people throughout the world and is among the five most common types of cancer in Brazil. The impact of the disease and its treatment in the patients life may cause physical, psychological, and social changes, thus affecting his quality of life. This study is an integrative literature review with the purpose to identify and ass

5. Fatigue in colo-rectal cancer patients: risk and predictive factors / Fadiga no doente com câncer colo-retal: fatores de risco e preditivos
INTRODUÇÃO: Não existem estudos preditivos sobre fadiga em doentes com câncer colo-retal, embora fadiga seja descrita como freqüente na população oncológica. OBJETIVO: Identificar os fatores de risco e preditivos independentes de fadiga em doentes com câncer colo-retal. MÉTODO: Estudo preditivo que envolveu amostra não-probabilística de 157 pacie

6. Immunohisthochemical expression of ErbB family receptors and their prognostic role in patients with colorectal cancer with high risk of recurrence after radical surgery / Perfil da expressão imunoistoquímica dos receptores da família ErbB e seu prognóstico em pacientes com câncer de cólon e reto com alto risco para recorrência após cirurgia radical
INTRODUÇÃO: Deve-se considerar que cerca de 70 a 80% dos pacientes portadores de carcinoma colorretal estádio II podem ser curados apenas com cirurgia. Por outro lado, a despeito do tratamento empregado e dos benefícios alcançados com a evolução dos tratamentos adjuvantes, cerca de 20 a 35% dos pacientes tratados com doença em estádio III vêm a fal

7. "Contribuição ao estudo da influência da radiação ionizante pré-operatória sobre a marcação do linfonodo sentinela do reto com azul patente: estudo experimental em ratos" / Contribution to the study of the influence of preoperative ionizing radiation on the identification of the sentinel lymph node with patent blue : an experimental study in rats
Previous ionizing radiation induces actinic alterations in peritumoral tissues and thus might influence the localization of the sentinel lymph node. The present study developed an experimental model for the localization of the sentinel lymph node of the rectum of the rat and for the definition of the dose of radiation (calibration curve). The objective was t

8. Determination of Cyclin G expression in rectal cancer / Determinação da expressão da Ciclina G no câncer do reto
Introduction: Identification of genetic mechanisms involved in colorectal cancer carcinogenesis led to the development of new treatment strategies such as gene therapy. The aim of this strategy is to interrupt cell-cycle of transformed malignant cells by blocking or stimulating specific gene expression. Utilization of cyclin G antisense constructs has been s

11. Efficiency of 6- and 12-punctures biopsies to detect prostate cancer in patients with PSA< 10 ng/mL and normal digital rectal examination
OBJECTIVE: Establish the efficiency of 6- and 12-punctures transrectal ultrasound-guided needle biopsies in low risk patients for prostate cancer. Six-punctures (sextant) biopsies were compared to 12-punctures biopsies, assessing which is the best strategy to detect this neoplasm. MATERIALS AND METHODS: Among 240 patients submitted to prostate biopsy, 54 wit

12. Tumor carcinóide do reto
The rectum is the second most common location of the carcinoid tumors of the gastrointestinal tract. It represents approximately one or two per cent of the rectal neoplasms. Metastases are less frequent and it presents a better prognosis than carcinoid tumors found in the digestive tract. Treatment is surgical and the technique to be used depends fundamental
