Second-line targeted therapy for metastatic colorectal cancer. Possibilities for choices

Abstract

The most effective first-and subsequent line drug regimens for metastatic colorectal cancer (mCRC) suggest the inclusion of targeted drugs (TD). The choice of TD for the second-line therapy takes into account not only the biological features of the tumor and the general condition of the patient, but also the option of the previous line therapy, its effectiveness and toxicity. Treatment with anti-EGFR antibodies (AT) did not significant improve overall survival (OS) in comparison with chemotherapy in the secondline regimens, in contrast to antiangiogenic drugs. Among this group of MAT, aflibercept provides the best results in a selected group of patients (the highly effective group) and a controlled toxicity profile.
