IMPORTANCE The EGFR inhibitors (EGFR-I) cetuximab and panitumumab and the angiogenesis inhibitors (AIs) bevacizumab and aflibercept have demonstrated varying efficacy in mCRC. OBJECTIVE To document the overall impact of specific chemotherapy regimens on the efficacy of targeted agents in treating patients with mCRC. DATA SOURCES MEDLINE, EMBASE and Cochrane databases were searched to 2014, ...

PURPOSE Evasion from chemotherapy-induced apoptosis due to p53 loss strongly contributes to drug resistance. Identification of specific targets for the treatment of drug-resistant p53-null tumors would therefore increase the effectiveness of cancer therapy. EXPERIMENTAL DESIGN By using a kinase-directed short hairpin RNA library and HCT116p53KO drug-resistant colon carcinoma cells, glycogen s...

The aim of the study was to compare efficacy and safety of first-line palliative chemotherapy with (EOX) epirubicin/oxaliplatin/capecitabine and (mDCF) docetaxel/cisplatin/5FU/leucovorin regimens for untreated advanced HER2-negative gastric or gastroesophageal junction adenocarcinoma. Fifty-six patients were randomly assigned to mDCF (docetaxel 40 mg/m(2) day 1, leucovorin 400 mg/m(2) day 1, 5F...

BACKGROUND The prognosis of patients with colorectal cancer is considered to be affected by several factors. Recently, chemotherapy for this disease has been demonstrated to be effective for long-term survival. In this study, the potential predictors, including chemotherapy regimens for survival after surgery, in patients with stage IV colorectal cancer are presented. PATIENTS AND METHODS Uni...

5-Fluorouracil (5FU), a widely used chemotherapeutic drug, inhibits the DNA replicative enzyme, thymidylate synthase (Tyms). Prior studies implicated a VNTR (variable numbers of tandem repeats) polymorphism in the 5'-untranslated region (5'-UTR) of the TYMS gene as a determinant of Tyms expression in tumors and normal tissues and proposed that these VNTR genotypes could help decide fluoropyrimi...

Purpose: Evasion from chemotherapy-induced apoptosis due to p53 loss strongly contributes to drug resistance. Identification of specific targets for the treatment of drug-resistant p53-null tumors would therefore increase the effectiveness of cancer therapy. Experimental Design: By using a kinase-directed short hairpin RNA library and HCT116p53KO drugresistant colon carcinoma cells, glycogen sy...

Abstract Introduction Despite the known cytotoxic and hepatotoxic effects of most common chemotherapy drugs, their use in context liver regeneration as part antitumor treatment is controversial. Methods Thirty-six WAG/RijHsd rats were induced to selective portal ligation 50% hepatic parenchyma, divided into 3 experimental groups. 72 hours before, two groups treated with 5-Fluorouracil (50mg/kg)...
