Less surgery but better survival rates for metastatic colorectal cancer patients, study finds

Patients with metastatic colorectal cancer are undergoing less surgery for tumor removal than before, and yet survival rates are improving, according to a study published in JAMA Surgery

Reserachers used the National Cancer Institute's Surveillance, Epidemiology and End Results database to identify 64,157 patients, all of whom were diagnosed with metastatic colon cancer. Overall, 43,273 underwent primary tumor resection.

The researchers found that the annual surgery rate decreased from 74.5 percent to 57.4 percent over the study period. They also found that the median relative survival rate of the patients improved from 8.6 percent to17.8 percent.
