Smoking Increases Risk of Mortality in CRC Survivors

A comprehensive study published in the Journal of Clinical Oncology found that colorectal cancer survivors who smoke cigarettes were at more than twice the risk of death than non-smoking survivors.

Existing evidence links smoking with higher chances of being diagnosed with colorectal cancer, but its association with survival after colorectal cancer diagnosis is unclear.

To investigate the association of smoking, before and after diagnosis, with all-cause and colorectal cancer-specific mortality among colorectal cancer survivors, researchers led by Peter Campbell, PhD, identified 2548 people newly diagnosed with invasive, non-metastatic colorectal cancer from among 184,000 adults in the American Cancer Society's Cancer Prevention Study II. Among the 2548 colorectal cancer survivors, 1074 died during an average of 7.5 years of follow-up time, including 453 as a result of colorectal cancer.
