Arms Assigned Interventions
Experimental: short-course CRT-5FU Radiation: Radiation: short-course preoperative chemoradiotherapy

Drug: 5-Fluorouracil 5-Fluorouracil is administered intravenously at a dose of 400 mg/m2 once daily continuous regimen during RT(5 days).

Radiation: Localization, simulation and immobilization Radiation dose and planning Total dose 25Gy, 5 fractions (5 Gy/day).

Detailed Description:

Radiotherapy using tomotherapy is delivered in 5 Gy daily fractions for a total of 25 Gy in 5 fractions.

A bolus injection of 5-fluorouracil (400 mg/m2/d)and leucovorin (20 mg/m2/d) is delivered concurrently on day 1-5 during radiotherapy.

Total mesorectal excision is performed within 6±2 weeks. The pathological response of downstaing is the study endpoint.
