RIGScan CR49 is used to locate cancerous tissue during surgery for patients with metastatic cancer of the colon or rectum (colorectal). In multicenter Phase II and pivotal Phase III clinical trials, RIGScan CR49 located tumor confirmed by pathology tests in 90 percent of evaluable patients who participated in the studies. The product found pathology-confirmed tumor that was missed by the surgeon and by preoperative diagnostic scans in one of five of the evaluable patients.
