title: [Precaution of over or under treatment for colorectal cancer].
abstract: Insufficient treatment and overtreatment in the management of colorectal cancer greatly influence patients' outcome. The clinicopathological stage of carcinoma located in colon and rectum is different for anatomical differences. The indication of adjuvant chemotherapy varies in colon or rectal cancer. Locally advanced rectal cancer should receive neoadjuvant treatment, however, the optimal regimen is still controversial.
