Akter S, Islam Z, Mizoue T, et al. - This pooled analysis of 10 population‐based cohort studies was performed to assess colorectal cancer (CRC) risk in relation to smoking status, smoking intensity, and smoking cessation in the Japanese population. A follow-up for 2,666,004 person‐years was performed among 363,409 participants, revealing 9,232 incident CRCs. A higher risk of CRC in men was reported among ever smokers vs never smokers. For CRC, colon cancer, distal colon cancer, and for rectal cancer, the estimated hazard ratios and 95% confidence intervals were 1.19 (1.10‐1.29), 1.19 (1.09‐1.30), 1.28 (1.13‐1.46), and 1.21 (1.07‐1.36), respectively. Smoking was found to be related to risk of CRC in a dose‐response manner. Overall, findings corroborated the presence of an increased risk of CRC in relation to smoking in Japanese men. A correlation of smoking with increased risk of distal colon cancer was also confirmed in Japanese women, as there was no significant gender difference seen in the link between smoking and CRC risk.
