• Meet the criteria for lateral lymph node metastasis (lymph node short diameter ≥7mm, or lymph node short diameter ≥5cm with uneven internal signals and no chemical shift effect, or irregular boundaries);
• The primary tumor was located in the rectum (hard tube proctoscopy indicated that the lower margin of the lesion was less than 10cm from the anus);
• Kastler score ≥70, ECOG score 0 or 1;
