aFOBT information was missing among 26 patients, including 13 in group of stage II and 13 in stage III; FOBT information was missing among 10 and 8 patients in groups of regional lymph node metastasis (Yes) and vascular and neural infiltration (Yes), respectively, and FOBT information was missing among 16, 26, and 18 patients in groups of regional lymph node metastasis (No), distant metastasis (No), and vascular and neural infiltration (No), respectively.
