Change of Circulating Tumor Cells During Laparoscopic or Transanal Endoscopic Surgery for Rectal Cancer.

Start date: October 18, 2021
Phase:
Study type: Observational

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.
