No distant metastases are detected on imaging studies, and radical resection is clinically feasible.\n\n 4\\. Age of 20 years or older on the date of consent. 5. ECOG Performance Status (PS) is 0 - 1 (PS 0 for age 71 years or older on the date of consent).\n\n 6\\. Previously untreated rectal cancer with the lower margin of the tumor within 12 cm of the anal verge (AV).\n\n 7\\. Patients with cT2N0M0 in the diagnosis before starting treatment (a lymph node with a short diameter of 7 mm or more is considered positive).\n\nThe conditions for lymph node metastasis shall be as follows. Contrast-enhanced CT or MRI (plain or contrast-enhanced) with a slice width of 5 mm or less.\n\n(i) Short diameter of 10 mm or more (ii) Short diameter of 7 mm or more and one or more of the following a) to c) are met\n\n(a) Edge irregularity (b) Low signal area with internal heterogeneity on MRI (c) Circular (long/short diameter ratio \\< 1.5) If contrast-enhanced CT is not possible due to contrast medium allergy, renal dysfunction, or bronchial asthma, simple CT is acceptable.\n\n8\\. The following criteria for major organ function within 14 days prior to registration are met.\n\nIf more than one test result exists within this period, the most recent one should be used. No blood transfusions or hematopoietic factor products should be administered within 14 days prior to the test date.\n\n1. Neutrophil count: greater than or equal to 1,500/mm3\n2.
