    Resistance to anti-epidermal growth factor receptor in metastatic colorectal cancer: What does still need to be addressed?

    No full text
    Colorectal cancer (CRC) represents a global health problem, being one of the most diagnosed and aggressive tumors. Cetuximab and panitumumab monoclonal antibodies (mAbs) in combination with chemotherapy are an effective strategy for patients with RAS Wild Type (WT) metastatic colorectal cancer (mCRC). However, tumors are often unresponsive or develop resistance. In the last years, molecular alterations in principal oncogenes (RAS, BRAF, PI3KCA, PTEN) in the downstream pathway of the epidermal growth factor receptor (EGFR) and in other receptors (HER2, MET) that converge on MAPK-ERK signalling have been identified as novel mechanisms of resistance to anti-EGFR strategies. However, further efforts are needed to better stratify CRCs and ensure more individualized treatments. Herein, we describe the consolidated molecular drivers of resistance and the therapeutic strategies available so far, with an overview on potential biomarkers of response that could be integrated in clinical practice

    Optimizing Anti-EGFR Therapy in Colorectal Cancer

    Treatment with anti-EGFR monoclonal antibodies has been successfully integrated in the continuum of care for metastatic colorectal cancer. The major challenge is the identification of patients who would benefit from treatment. Currently, the best predictor of efficacy is the absence of mutations in KRAS and NRAS genes.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
