This study is a single-center, open, prospective, single-treatment trial (pilot study). This study aims to analyze the treatment results after receiving capecitabine adjuvant chemotherapy for 4 months after non-surgical treatment in patients who had completed and could have clinical complete remission with capecitabine preoperative chemoradiotherapy with capecitabine for mid-to-lower rectal cancer and to investigate the feasibility of non-surgical treatment.
