[Treatment of colorectal cancer with unresectable metastasis with chemotherapy without primary tumor resection: analysis of tumor-related complications].

Introduction: Although the conventional treatment of patients with stage iv colorectal cancer involves resection of the primary tumor followed by chemotherapy, several studies suggest that in patients with few symptoms the first and only treatment should be chemotherapy. The objective of this study is to analyze the complications related to the primary tumor in a series of patients with unresectable metastatic colorectal cancer treated with chemotherapy without surgery.

Material And Methods: Retrospective descriptive study.

Phase II study of preoperative radiotherapy and concomitant weekly intravenous oxaliplatin combined with oral capecitabine for stages II-III rectal cancer.

Introduction: A prospective phase II study was conducted to assess the clinical activity and tolerability of oxaliplatin, capecitabine, and radiotherapy (RT) for neoadjuvant therapy of stages II-III rectal cancer.

Materials And Methods: Patients with histologically confirmed stages II-III (T3-T4 and/or N+) resectable rectal adenocarcinoma were eligible. Capecitabine was administered at 825 mg/m(2) twice daily for 5 days/week and oxaliplatin at 50 mg/m(2) on day 1 weekly for 5 weeks starting the first day of RT (before RT).

Snail1 protein in the stroma as a new putative prognosis marker for colon tumours.

Over-expression of Snail1 gene transcriptional repressor promotes an epithelial-to-mesenchymal transition in epithelial tumour cell lines. Expression of Snail1 RNA has been associated to the pathogenesis of a number of malignancies; however, the lack of good monoclonal antibodies against this protein has precluded a definitive analysis of Snail1 protein. In this study, we aimed to determine the expression of this transcriptional factor in colorectal tumours.

A Phase II study of preoperative radiotherapy and concomitant weekly irinotecan in combination with protracted venous infusion 5-fluorouracil, for resectable locally advanced rectal cancer.

Purpose: The aim of this study was to evaluate the efficacy and tolerance of preoperative chemoradiotherapy (CRT) with irinotecan (CPT-11) and 5-fluorouracil (5-FU) in patients with resectable rectal cancer.

Methods And Materials: Patients with resectable T3-T4 rectal cancer and Eastern Cooperative Oncology Group performance status <2 were included. CPT-11 (50 mg/m(2) weekly) and 5-FU (225 mg/m(2)/day continuous infusion, 5 days/week) were concurrently administered with radiation therapy (RT) (45 Gy, 1.

Cofactors associated with liver disease mortality in an HBsAg-positive Mediterranean cohort: 20 years of follow-up.

The risk of developing liver cancer in hepatitis B virus (HBV) carriers differs across geographical areas, suggesting that exposure to other risk factors may contribute to HBV-linked cancer risk. Our study estimates the mortality due to liver disease and the role of other risk factors in a Spanish HBV cohort. 2,352 hepatitis B surface antigen (HBsAg)-positive and 15,504 HBsAg-negative subjects were identified among blood donors during 1972-1985 and were followed until December 2000 through the Mortality Registry.
