1. Primary Adenocarcinoma at Colostomy Site: Report of a Clinical Case
Abstract Colorectal cancer (CRC) is the fourth most frequently diagnosed cancer in the United States and it is found in 17% of patients thought to have complicated diverticular disease. However, primary adenocarcinoma rarely occur in the colostomy site and the risk of developing malignancy is similar to that of any other colonic segment. Polyps found in CRC

2. Colorectal Cancer: Comparative Analysis Between Two Series of Patients Separated by More Than Three Decades
Abstract Aim This study characterizes Colorectal Cancer (CRC) incidence in the University Hospital Ramon and Cajal, Madrid, and analyzes variations over time. It establishes risk groups, aiming to discover whether diagnosis can be determined in less advanced stages of disease. Method Evolutionary epidemiological study of genetic and environmental factors c

3. STUDY OF LIPID BIOMARKERS OF PATIENTS WITH POLYPS AND COLORECTAL CÂNCER
RESUMO CONTEXTO: O câncer colorretal (CCR) é, mundialmente, uma das principais causas de câncer. Métodos de diagnóstico precoce através de biomarcadores séricos são necessários. O estudo das ômicas, mais recentemente a lipidômica, tem a finalidade de analisar os lipídeos para melhor compreensão do lipidoma humano. A evolução dos métodos de

4. Hyoscine butylbromide for colorectal polyp detection: prospective, randomized, placebo-controlled trial
OBJECTIVES: The removal of pre-malignant colorectal lesions prevents cancer. Hyoscine has been proposed as a means of improving diagnosis by reducing colonic movements. The aim of this study was to analyze whether this anti-spasmodic enhances the detection of pre-malignant colorectal lesions. METHODS: In a randomized, double-blinded fashion patients receiv

5. Receptores de estrógeno e progesterona, Ki67, Bcl-2 E Cox-2 em pólipos endometriais de mulheres na pré e pós-menopausa e associação com a obesidade, = : Estrogen and progesterone receptors, Ki67, Bcl-2 and Cox-2 markers in benign endometrial polyps in pre and postmenopausal women and their association with obesity / Estrogen and progesterone receptors, Ki67, Bcl-2 and Cox-2 markers in benign endometrial polyps in pre and postmenopausal women and their association with obesity
Introdução: A prevalência de obesidade tem aumentado em todo o mundo e hoje já representa um problema de saúde pública. Na população feminina, seu aumento ocorre principalmente nos anos próximos da transição para menopausa. O aumento de peso representa um risco para diversas comorbidades, dentre elas um importante fator de risco para patologia end

6. Comparison of blood neoangiogenesis and lymphatic vascularization in colorectal adenomas from patients with and without concomitant colorectal cancer
Blood and lymphatic vessel proliferation is essential for tumor growth and progression. Most colorectal carcinomas develop from adenomas (adenoma-carcinoma sequence) in a process due to accumulation of molecular genetic alterations. About 5% of adenomatous polyps are expected to become malignant, but data on the differential angiogenic patterns of these lesi

7. Inflammatory and apoptosis pathway in ileal pouches of patients with ulcerative colitis and familial adenomatous polyposis / Estudo da atividade inflamatoria e apoptose em reservatorios ileais de doentes operados por polipose adenomatosa familiar e retocolite ulcerativa inespecifica
Ileal pouch-anal anastomosis is the surgical procedure of choice for patients with refractory ulcerative colitis (UC) and for familial adenomatous polyposis (FAP) with rectal polyps. Pouchitis is the most common complication in UC, while it is quite rare in FAP. Objective: Evaluate the inflammatory and apoptotic activity in endoscopically normal ileal pouch

8. Analise de 153 pacientes portadores de polipos gastricos, em 26000 endoscopias digestivas realizadas no Gastrocentro-UNICAMP
Among twenty-six thousands digestive endoscopies, we diagnosed gastric polyps in 153 patients. The aim of this study is a retrospective review gastric polyps, in this series, derived from gastric mucosal epithelium to analyze their histological classification, location, size, Yamada?s classification, histolological findings and treatment. The patients includ

9. Effects of sulindac on sporadic colorectal adenomatous polyps.
BACKGROUND: Although sulindac is known to cause regression of colorectal adenomatous polyps in familial adenomatous polyposis, less is known about the effect of sulindac on sporadic adenomas. The precise mechanisms of these effects also remain to be determined. AIMS: Sulindac was given to patients with sporadic colorectal adenomatous polyps to evaluate its e

10. Ploidy studies in adenomatous polyps of the colon.
The nuclei of colonic adenomatous polyps and some colonic carcinomas have a normal diploid profile. The remaining carcinomas are aneuploid, and this change most probably occurs after the dysplasia that determines invasiveness, because even adenomatous polyps with carcinoma in situ are diploid.

11. Pseudo-carcinomatous invasion in adenomatous polyps of the colon and rectum
The histology of pseudo-carcinomatous invasion in adenomatous polyps of the colon and rectum is described and the appearances are contrasted with those seen in malignant polyps.

12. Familial polyposis coli: heterogeneous polyp expression in 2 kindreds.
We describe 2 extended kindreds supposedly manifesting familial multiple adenomatous polyposis coli (FPC), but which show marked heterogeneity in the phenotypic expression of colorectal adenomatous polyps. In one family, 2 individuals had diffuse polyposis at very early ages (7 and 10 years), while 6 others (aged 23 to 72 years) had solitary polyps only. Of
