Colon Cancer Research: Tumor location predicts survival

CINCINNATI (WKRC) - There is breakthrough information that could change the odds of survival for those diagnosed with colon cancer. Researchers at The Ohio State University Comprehensive Cancer Center were part of the team that authored a new study. It's the largest study to date that looked at tumor location, left side versus right side, in those with colorectal cancer that has already spread. They found significant differences in outcomes even though overall patients in the study lived about 30 months. Dr. Richard Goldberg said, "But then we dug down deeper into the research and discovered patients with right-sided colon cancers did not do as well as patient with left sided colon cancer." Dr. Goldberg said patients did have different treatment regimens but even with that those with left sided tumors lived as long as 33 months with those with right sided as low as 19 months. While early detection was always key to surviving the cancer, colonoscopies he said were critical for those ages 50 and older or younger in those with a strong family history of the disease. But he also said it appeared the biology of the tumors was different. Certain chemotherapy drugs did appear to work better for tumors on one side compared to the other which means providers need to consider this when targeting therapy. "What does all this mean? When I sit down with a patient with left sided colon cancer I am going to advise them differently than I did before, than when I sit down with a patient with one that's right sided colon cancer," said Dr. Goldberg. The location is determined by the primary tumor, or the side on which the original cancer is found. That information comes from a larger on-going trial colorectal cancer, there are patients enrolled in it in the Tri-State. It was presented Wednesday, May 18, at the American Society of Clinical Oncology's annual meeting in Chicago.
