摘要: Anti-EGFR therapy in metastatic colorectal cancer (mCRC) has improved survival outcome. However, many patients do not respond to this and almost all develop resistance after a few months of treatment. Since 2008, the been restricted without mutations KRAS, an important target EGFR pathway, as these benefit from anti-EGFR therapy. Recently, changed all-RAS wild-type strategy. Despite restrictions, still 40 60 % mCRC are resistant. New biomarkers need be identified order improve patient selection. Another problem is tumor heterogeneity, which impedes detection genes can consequently lead wrong treatment decisions. A possible solution for may found liquid biopsies. In review, known promising upcoming associated with will summarized. Moreover, potential added value biopsies selection follow-up discussed.
