[Standardized treatment of mid-low rectal cancer]

In recent years, the treatment strategy of mid-low rectal cancer has changed from surgical resection alone to multidisciplinary treatment. In order to offer the greatest benefits to the mid-low rectal cancer patients, it is necessary to carry out the preoperative TNM staging for appropriate therapeutic strategies. Total mesorectal excision (TME), preoperative TNM staging and neoadjuvant chemoradiotherapy together may achieve a breakthrough in the therapeutic outcome of mid-low rectal cancer.
