The prognostic role of KRAS and BRAF in patients undergoing surgical resection of colorectal cancer liver metastasis: a systematic review and meta-an…

2016

Background: Clinical trials investigated the potential role of both KRAS and BRAF mutations, as prognostic biomarkers, in colorectal cancer (CRC) patients who underwent surgical treatment of liver metastasis (CLM), showing conflicting results. This meta-analysis aims to review all the studies reporting survival outcomes (recurrence free survival (RFS), and/or overall survival (OS)) of patients undergoing resection of CLM, stratified according to KRAS and/or BRAF mutation status. Materials and Methods: Data from all published studies reporting survival outcomes (RFS and/or OS) of CRC patients who received resection of CLM, stratified by KRAS and/or BRAF mutation status were collected by sear…

Colorectal cancer: An update on the effects of lycopene on tumor progression and cell proliferation

2017

Colorectal cancer (CRC) is one of the most common cancers worldwide. Various factors, including oxidative stress, where excessive productions of reactive oxygen species (ROS) and reactive nitrogen species (RNS) occur, contribute to its pathogenesis. Numerous studies have investigated the effect of antioxidant substances derived from food such as fruits and vegetables; however, data on Lycopene are still rare. Studies on HT-29 colorectal cancer cells and on animal models have shown that lycopene has effects on cell proliferation and on the progression of the CRC by interacting with various cellular signaling pathways. This analysis of the literature focused on the antioxidant effect of lycop…

MicroRNAs in Colorectal Cancer Drug Resistance: Shooters become Targets

2013

This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. MicroRNAs (MiRNAs) are involved in the regulation of several biological processes such as development, differentiation, metabolism, apoptosis and proliferation. Recently, it has been shown that deregulated expression of miRNAs are present in different human cancers, suggesting a potential role in carcinogenesis [1,2]. Recent evidence suggests that miRNAs may represent potential new therapeutic approaches in patients with dru…

“Randomised trial comparing biweekly oxaliplatin plus oral capecitabine versus oxaliplatin plus i.v. bolus fluorouracil/leucovorin in metastatic colo…

2009

PURPOSE: Oxaliplatin combined with either fluorouracil/leucovorin (OXAFAFU) or capecitabine (OXXEL) has a demonstrated activity in metastatic colorectal cancer patients. We aimed at comparing these two regimens in terms of response rate (RR), safety, progression-free survival (PFS), and quality of life (QoL) of patients. METHODS: A total of 322 patients with metastatic colorectal cancer were randomized to receive biweekly: oxaliplatin 100 mg/m(2) i.v. on day 1, capecitabine 1,000 mg/m(2) orally twice daily from day 1 to day 11 (OXXEL); or oxaliplatin 85 mg/m(2) i.v. on day 1; 6S-leucovorin 250 mg/m(2) i.v. and fluorouracil 850 mg/m(2) i.v. on day 2 (OXAFAFU). RESULTS: Eleven complete and 42…

Differing expression of metalloprotease and of adhesion molecules in signet-ring cell and intestinal colorectal carcinoma.

2009

Abstract. Background: Pure signet-ring cell colorectal carcinoma (SRCC) is an infrequent and highly malignant histological variant of colorectal cancer (CRC), while it is present as a histological component in colorectal carcinomas more frequently. Materials and Methods: The aim of this work was to widen the knowledge of the biological factors involved in the pathogenesis and aggressiveness of SRCC by the identification and evaluation of possible molecular abnormalities. By means of immunohistochemistry the expression of the proteolytic degradation enzyme matrix metalloprotease (MMP)-1, that is a collagenase specifically degrading collagens I, II, III and of the adhesion proteins Ecadherin,…

COLORECTAL CANCER AND INFLAMMATORY BOWEL DISEASES: EFFECTS ON DIET AND ANTIOXIDANTS

2017

It is well established that oxidative stress is common in inflammatory bowel diseases (IBDs). Accordingly, antioxidants are recommended for treatment. The aim of this study is to compare the effects of antioxidants contained in the various types of tea on symptoms and evolution of IBD and colorectal cancer (CRC). Analysis of the literature revealed that the theaflavin-3, 30-digallate (TFDG) contained in black tea, and epigallocatechin-3-O-gallate (EGCG) contained in green tea have protective effects against oxidative stress. Moreover, these substances are involved in many biochemical processes responsible for inflammation and proliferation of cancer cells. It is documented that both TFDG an…

TARGETED THERAPIES FOR INFLAMMATORY BOWEL DISEASES AND COLORECTAL CANCER: AN INCREASING NEED FOR MICROBIOTA-INTESTINAL MUTUALISM

2015

The involvement of intestinal microbiota and dysbiosis in the pathogenesis for inflammatory bowel disease (IBD) and colorectal cancer (CRC) is a well-established factto be taken into real consideration when developing targeted therapies. This review aims to depict how advances in our understanding of the role of intestinal flora in the pathogenesis of IBD and CRC are shaping up the therapeutic protocols of their management. It is demonstrated of their management. It is demostrated that there is a circadian regulation of colocyte gene expression in response to microbiota. Dysbiosis leading to a decrease in microbiome biodiversity is also described in IBD patients in IBD patients whereby thic…
