The findings add to the arsenal of reasons why colon cancer patients, and all cancer patients, need to complete their chemotherapy regimens whenever possible.


Previous studies have shown that not completing chemotherapy regimens for breast cancer is associated with shorter survival. This is the first study to look at a link between mortality rates from colon cancer and treatment adherence.
