New hope for Tough-to-Treat colorectal cancer? drug trial uses ultrasound to predict success

This study tested a drug called axitinib against a placebo in 52 people with advanced colorectal cancer that had spread to the liver and stopped responding to chemotherapy. The goal was to see if axitinib could help control the cancer and to test a special ultrasound technique that measures blood flow to tumors to predict how well a patient might respond. The trial is complete, and results focus on survival differences between those whose tumors showed a blood flow reduction and those who did not.
