(Medscape—October, 28, 2013) Increased tobacco use by colorectal cancer patients decreases positive outcomes after surgery. A study in the Annals of Surgery by A Sharma et al. looked at 47,574 patients with colorectal polyps or cancer. Of this group, the smokers had a 30 percent increased risk for complications and a 50 percent increased risk for death after colorectal surgery. Smoking risk is evaluated based on duration and pack-years. Ex-smokers, defined as those who quit at least a year prior to surgery, had better outcomes than current smokers.
