An Evolving Landscape: New Therapies for Metastatic Colorectal Cancer.

Substantial progress is being made in the development of novel therapies directed against colorectal cancer. The discovery of various molecular markers and advances in tumor profiling have facilitated the development of new targeted agents and immunotherapy. Not only have these drugs improved progression-free survival and even overall survival in some cases, but their related outcomes have also raised questions as to how to best combine or sequence therapies for even greater efficacy. Furthermore, we are beginning to understand how these combination therapies may yield for greater therapeutic response for patients with microsatellite stable colorectal cancer for which there is much need for improvement. In this article, we review recent trial data and explore the outcomes of various targeted therapies and immunotherapies for patient with advanced colorectal cancer.
