| Summary: | Margaret Byrne, Muhammad Wasif Saif Northwell Health Cancer Institute, Donald and Barbara Zucker School of Medicine at Hofstra, Lake Success, NY, USA Abstract: Survival of patients with metastatic colorectal cancer (mCRC) has significantly improved in the last decade. Survival gains are not driven by advances in first-line therapy but by incremental additional effects of subsequent treatment lines. To maximize outcomes, patients should receive all active agents. Identification of patient subgroups is increasing individualization of treatment. Novel oral agents, such as regorafenib and TAS-102, as well as promising immunotherapeutic agents have offered salvage treatment options for refractory mCRC. Although most therapeutic developments for mCRC in the chemorefractory setting focuses on new targets and/or more potent agents, reconsideration of established targets has gained importance with the growth of a rational pharmacogenomic approach to drug development, such as HER2. The authors describe treatment options for patients with refractory colon cancer following first- and second-line therapy.
