چکیده

BACKGROUND the present study evaluates genetic polymorphisms of three glutathione S-transferases (GSTM1, GSTT1and GSTP1) in patients with synchronous malignant colorectal tumors and the association of synchronous colorectal cancers with other cancers. MATERIAL AND METHODS from 420 patients with a colorectal cancer admitted to our hospital between 2005-2012, we selected for genetic analysis 20 patients with multiple synchronous malignant colorectal tumors and 9 patients with asynchronous association of colorectal cancer with another cancer. We searched for GST genotypes, comparing the results with controls. RESULTS the genetic analysis was possible only in 19 patients with colorectal synchronous cancers and 9 patients with asynchronous association of colorectal cancer with another cancer; we found a statistically significant difference for null GSTM1 genotype frequency between these patients and the control group; we found no differences regarding the frequency of null GSTT1 genotype and Ile105Val polymorphism of GSTP1 in patients with synchronous cancers compared with the control group. CONCLUSION in our study we found the null GSTM1 genotype as a risk factor for multiple colorectal synchronous cancers and for an association of synchronous colorectal with other cancers

Colorectal and Vulvar Synchronous Cancer: A Case Report

Synchronous cancer is referred to two or more histological distinct malignancies diagnosed during the same hospital admission. Globally more than 1 million people get colorectal cancer yearly resulting in about 0.5 million deaths. Vulvar cancer is the fourth most common gynecologic cancer (following the corpus uterine cancer, cancer of ovary and cervix) and comprises only 4 percent of malignanc...

SYNCHRONOUS SURGICAL REMOVAL OF SUSPICIOUS OVARIAN METASTASES FROM COLORECTAL CANCER

Metastatic ovarian cancers occur in 3-8 percent of women undergoing surgical resection of a primary colorectal cancer. In this study we examined the characteristics of women with colorectal cancer for whom synchronous oophorectomy had been performed. In this cross-sectional study, records of patients with colorectal cancer from April 1991 through October 1999 who had undergone surgery for ...

Microsatellite Instability of Gastric and Colorectal Cancers as a Predictor of Synchronous Gastric or Colorectal Neoplasms

BACKGROUND/AIMS Microsatellite instability (MSI) plays a crucial role in gastrointestinal carcinogenesis. The aim of this study was to clarify whether MSI is a useful marker for predicting synchronous gastric and colorectal neoplasms. METHODS Consecutive patients who underwent both esophagogastroduodenoscopy and colonoscopy before the resection of gastric or colorectal cancers were included. ...
