Hospital Department: Daqing Oil City Hospital, Department of Anorectal Surgery Li Xinxiang, Department of Colorectal Surgery, Cancer Hospital of Fudan University Replies: The first treatment for cancer patients is crucial, so it is very important to choose a good professional doctor. We have seen too many patients who missed their chance in outside hospitals due to irregular treatment, which is really a pity. As for whether it is suitable for anal preservation, distance is only one of the factors, which needs comprehensive assessment and requires patients to come to the hospital for physical examination. Rectal cancer requires preoperative staging to determine whether neoadjuvant radiotherapy is needed.
