Colorectal cancers (CRCs) evolve by a reiterative process of genetic diversification and clonal evolution. The molecular profile of CRC is routinely assessed in surgical or bioptic samples. Genotyping of CRC tissue has inherent limitations; a tissue sample represents a single snapshot in time, and it is subjected to spatial selection bias owing to tumor(More)
Oxaliplatin (OXA), raltitrexed (RTX), 5-fluorouracil (FU) and folinic acid (FA) have shown activity in metastatic colorectal cancer, radioenhancing effect and synergism when combined. We evaluated a chemotherapy (CT) combination of OXA, RTX and FU/FA during preoperative radiotherapy (RT) in locally advanced rectal cancer (LARC) patients. Fifty-one patients(More)
UNLABELLED 18F-FDG PET is a useful tool for assessing the effects of chemo- or radiotherapy. The aim of this study was to correlate the change in tumor 18F-FDG standardized uptake value (SUV) during and after preoperative radiochemotherapy, with the pathologic response achieved in locally advanced rectal cancer (LARC) patients. METHODS Thirty-three(More)
PURPOSE Epidermal growth factor receptor (EGFR) overexpression has been implicated in the development of head and neck squamous cell carcinomas (HNSCC) and represents a potential therapeutic target for this disease. We have reported previously that growth inhibitory concentrations of IFN-alpha enhance the expression and activity of EGFR and that this effect(More)
Metformin, an inexpensive, well-tolerated oral agent that is commonly used in the first-line treatment for type 2 diabetes, has become the focus of intense research as a potential anticancer agent. This research reflects a convergence of epidemiologic, clinical, and preclinical evidence, suggesting that metformin may lower cancer risk in diabetics and(More)
Tropospheric inhomogeneities can form a major error source in differential synthetic aperture radar interferometry measurements, which are used in slow-deformation monitoring. Indeed, variations of atmospheric conditions between two radar acquisitions produce variations in the signal path of two images and, thus, additional fringes on differential(More)
The addition of bevacizumab to oxaliplatin-based chemotherapy significantly improved progression-free survival (PFS) in patients with metastatic colorectal cancer (CRC). An increased risk of arterial thromboembolic events has been observed in some trials in older patients, and the potential benefit of a maintenance therapy with bevacizumab alone has not(More)
Background:Potentiation of anticancer activity of capecitabine is required to improve its therapeutic index. In colorectal cancer (CRC) cells, we evaluated whether the histone deacetylase-inhibitor vorinostat may induce synergistic antitumour effects in combination with capecitabine by modulating the expression of thymidine phosphorylase (TP), a key enzyme(More)
Despite the introduction of several novel anticancer agents almost 50% of colorectal cancer (CRC) patients die for cancer suggesting the necessity of new therapeutical approaches. In this study we demonstrated that the HDAC inhibitor vorinostat exerted potent antiproliferative effect in a panel of mut- and wt-p53 human CRC cell lines. Moreover, in(More)
BACKGROUND Docetaxel is one of the most promising new drugs against squamous-cell carcinoma of the head and neck (SCCHN), while cisplatin is one of the most active single agents. A phase I study has shown the feasibility of the combination of the two drugs, and activity in SCCHN has been seen. PATIENTS AND METHODS Patients with locally advanced,(More)
