\u2666 <\/strong>Translational Studies with anti-EGFR therapy<\/span><\/p>\n

Clinical reports with the use of monoclonal antibodies directed against the ligand-binding site of the epidermal growth factor receptor (EGFR) have shown practice-changing results in the treatment of colorectal cancer and will hopefully further improve in the next future available therapeutic options for patients diagnosed with this highly deadly disease.<\/span><\/p>\n

In first-line, randomised trials objective response rate approached in fact 50-60% with the use of chemotherapy in combination with anti-EGFR treatment (cetuximab or panitumumab), thus suggesting that a nonnegligible proportion of patients, ranging from 50% to 40%, did not fully benefit from the use of anti-EGFR targeted antibodies although in the absence of a mutation of the RAS genes.  Most of the biological factors analysed in the attempt to improve patients selection in this setting focused either on the EGFR-downstream signalling pathway or on the receptor itself. Published research data suggested that EGFR gene copy number, PI3KCA mutations and BRAF mutational status may all represent predictive determinants for anti- EGFR therapy. However these factors were not incorporated into clinical practice particularly because prospective validation is lacking. Biologically enriched, prospective clinical trials are clearly needed in order to further identify the proportion of patients more likely to benefit from the use of first-line anti-EGFR antibodies. We then designed translational analyses in order to prospectively define a molecular panel able to identify patients more likely to benefit from the use of first-line anti-EGFR treatment in combination with chemotherapy.<\/span><\/p>\n

\u2666<\/strong> Translational Studies with treatment directed against tumour-driven angiogenesis<\/span><\/span><\/p>\n

Tumour-driven neoangiogenesis represents one of the main biological target of regorafenib. Molecular mechanisms underlying angiogenesis may be then considered as potentially interesting in the search of predictive factors for clinical outcome during regorafenib. Preliminary findings from our group suggested, that the VEGF-A rs2010963 polymorphism might have an independent correlation with PFS and OS (respectively HR: 0.49, 95% CI: 0.33-0.81, p=0.003 and HR: 0.52, 95% CI: 0.34-0.99, p=0.04). On the other hand further analyses focused on factors such as neutrophil to lymphocyte ratio, platelets count and LDH serum levels to define a biological profile of responding\/resistant patients. Unfortunately these factors have been all analysed separately and, more importantly, retrospectively, thus preventing clinicians to incorporate findings from these studies into clinical practice.  Pre-treated colorectal cancer patients, clinically candidates to treatment with regorafenib as per label indication in Italy will be then prospectively analysed for the panel of clinical and biological markers resulted independently associated with clinical outcome in order to prospectively define a molecular panel able to identify patients more likely to benefit from the use of first-line anti-EGFR treatment in combination with chemotherapy.<\/span><\/p>\n

\u2666 <\/strong>Aim of the ongoing studies<\/span><\/span><\/p>\n

Results from these studies will hopefully allow us to verify whether a prospective patients stratification based on genetic and clinical profiling analysed before the start of treatment, will be able to predict patients\u2019 clinical outcome.  These findings will ultimately help clinicians to optimize patients\u2019 selection for regorafenib and anti-EGFR treatment, reducing unnecessary toxicities for patients unlikely to benefit from such a treatment approach.<\/span><\/p>\n
