  1. “#” indicates that TNM-stage of 35 (31.3%) patients were confirmed according to pelvic MRI and CT of chest and abdomen, as they had received neoadjuvant therapy before surgery. “Unavailable” denotes the data was not acquired. NAT, neoadjuvant therapy. AT, adjuvant therapy. SODM, single organ distant metastasis. MODM, multiple organ distant metastases. LRDM, Local recurrence and distant metastasis. MRF, mesorectal fascia. EMVI, extramural venous invasion
