Brief summary

5-Fluorouracil (5-FU) based chemoradiotherapy is regarded a standard perioperative treatment in locally advanced rectal cancer, but the effective rate still low. We investigate oral TAS-102 plus oxaliplatin concurrent radiotherapy for stage II or III local advanced rectal cancer.

Other eligibility criteria comprise: WHO status of zero or one; adequate liver, renal, and bone marrow function defined as follows: leucocyte count \> 3,500/µl, thrombocyte count \> 100,000/µl, hemoglobin \> 10.0 g/dl; serum bilirubin \< 2.0 mg/dl, serum creatinine \< 2.0 mg/dl.

Exclusion criteria

* Prior treatment for rectal cancer, prior chemo- or immunotherapy, prior pelvic radiotherapy, or a history of other malignant diseases within the past five years with the exception of successfully treated basal carcinoma of the skin or carcinoma in situ of the uterine cervix. * Participation in another trial, pregnancy, breast-feeding, unwillingness to use effective contraception, or a medical condition or concomitant illness which could potentially interfere with compliance to the protocol are regarded as
