Study Description

Brief Summary: The primary purpose of this study is to compare the changes of circulating tumor cells (CTCs) at different time points in rectal cancer patients undergoing laparoscopic or transanal endoscopic radical resection. Our secondary purpose is to explore the effects of perioperative circulating tumor cells on tumor recurrence and metastasis.

Detailed Description: Mid-low rectal cancer is one of the common malignant tumors and the incidence has increased significantly in recent years. At present, surgery is still the most important and effective method for the treatment of mid-low rectal cancer. Traditional laparoscopic surgery and emerging transanal total mesorectal excision (TaTME) are the main methods. More than one-third of rectal cancer patients will eventually occur local recurrence and distant metastasis, which are the most important factors affecting prognosis. Circulating tumor cells may lead to distant metastasis, so the detection of CTCs in blood has important clinical significance in predicting the recurrence and metastasis of rectal cancer and monitoring treatment response. Due to the different degrees of contact between distinct surgical methods, this may lead to an increase in the quantity of CTCs in the blood, which may affect the prognosis of patients. Therefore, the investigators conducted a randomized controlled study to compare the changes in the quantity of CTCs in the central vein before, during and after operation in rectal cancer patients undergoing transanal endoscopic or laparoscopic radical resection. To explore the effect of two surgical methods on the risk of micrometastasis, and to provide evidence for the selection and improvement of rectal cancer treatment.
