TUMOR “SIDEDNESS” in colon cancer has become a topic of great interest, after right-sided tumors were shown to have a worse prognosis than left-sided ones and biologics were found to differ in efficacy based on side. At the 2017 ASCO Annual Meeting, studies explored why this might be so. Three...
On June 29, the U.S. Food and Drug Administration (FDA) granted marketing approval to the Praxis Extended RAS Panel, a next-generation sequencing test to detect certain genetic mutations in RAS genes in tumor samples of patients with metastatic colorectal cancer. The test is used to aid in the...
