Trends in epidemiology, treatment and molecular testing of metastatic colorectal cancer in a real-world multi-institution cohort study.

Metastasectomy in mCRC may be beneficial regardless of the anatomical site of metastasis. The adoption of next-generation sequencing techniques for molecular genetics testing coincided with a slightly increased rate of detection of KRAS and BRAF mutations, potentially reflecting greater test sensitivity. Further translational research is required in mCRC to define novel targets for treatment.
