1)Written informed consent obtained
2)Histological diagnosis of primary colorectal adenocarcinoma.
3)No distance metastases with CT or PET
4)Age >= 20 year old.
5)ECOG 0 or 1. If Age >= 75 year old, ECOG 0.
6)Treatment-naive patients with rectal cancer and clinically resectable rectal cancer located within 12cm from their anal verge.
7)Clinical stage of cT3-4 N0 M0 or TanyN+M0
8)Sufficient organ functions
1. Received one of the following treatments,
a. Extensive surgery within 4 weeks (excluding CV port)
b. Any anti-cancer drug treatment within 4 weeks
c. Irradiation within 4 weeks
2. Have a complication or history of severe lung disease (interstitial pneumonia, pulmonary fibrosis, severe emphysema, etc.).
3. Cases with a colon stent for stenosis
4. Cases with serious comorbidities (heart failure, renal failure, liver failure, hemorrhagic peptic ulcer, intestinal paralysis, intestinal obstruction, uncontrolled diabetes, etc.)
5. Cases with active multiple cancers (simultaneous multiple cancers or metachronous multiple cancers with a disease-free period of 5 years or less). However, cancer in situ (carcinoma in situ) or lesions equivalent to intramucosal cancer that are cured by local treatment are not considered to be active multiple cancers.
