Neoadjuvant radio-chemotherapy is a standard approach for patients with rectal adenocarcinoma. We want to test the possibility of adding chemotherapy to short course radiotherapy to enjoy the combined modalities benefits. In this single arm quasi experimental study patients with rectal adenocarcinoma located at 5 to 15 centimeters from anal verge without previous pelvic radiotherapy and chemotherapy will be enrolled. Individuals intolerant for chemotherapy, with existent other concomitant malignancy and distant metastasis will be excluded. Our estimated sample size is 30 people with attrition and lost to follow up taken account. The participant will undergo short course radiotherapy consisted of 25 gray in 5 fractions in 5 days with concurrent chemotherapy. Three weeks after completion of radiotherapy, participants receive one cycle of chemotherapy and then undergo total mesorectal excision surgery 8 week after last session of radiotherapy. The patients will be followed regularly for complications due to radiotherapy and chemotherapy before and after surgery to 30 days (for perioperative morbidity and mortality). Our primary outcome will be feasibility of such approach and secondary outcome would be pathologic response to neoadjuvant treatment.
