Selection of Therapeutic Strategies after Preoperative Neoadjuvant Chemoradiotherapy for Rectal Cancer

Rectal cancer is one of the most common malignant tumors in China, which is mainly middle and low rectal cancer. Due to the particularity of the physiological and anatomical location of the rectum and the neglect of the relevant clinical symptoms, patients with rectal cancer in real life often have the local progression stage. A large number of studies have shown that neoadjuvant chemoradiotherapy should be performed in such patients, to achieve tumor downstaging before rectal cancer surgery. In this study, different treatment measures for rectal cancer patients after neoadjuvant chemoradiotherapy are presented.
