Rectal neuroendocrine tumor is not necessarily cured after surgery. The malignancy of rectal neuroendocrine tumor is relatively low and the morbidity rate is also low. Generally, after early surgical resection and treatment, without recurrence within five years, most of the patients can achieve clinical cure. In case of advanced rectal neuroendocrine tumor, it is necessary to cooperate with radiotherapy and chemotherapy after surgery to avoid spreading or metastasis of cancer cells. Therefore, it does not mean that rectal neuroendocrine tumor is cured after having surgery. After having surgery for rectal neuroendocrine tumor, patients are advised to actively cooperate with professional oncologists for follow-up treatment and go to the hospital for rechecking regularly to keep abreast of the changes in condition as well as recovery. After the surgery, patients should also control their diet, focusing on fluids and easy-to-digest food, and keep the diet light, which will help the recovery after the surgery.
