Primary Outcome Measures:
  • To evaluate the pathologic response [ Time Frame: After surgery with pathology data ]

Secondary Outcome Measures:
  • Tumor regression grade & MR volumetry [ Time Frame: After surgery with pathology data for TRG, at the pretreatment work-up and 1-4 days befor surgery ]
    To evaluate the tumor regression grade & MR volumetry

  • Acute/ late toxicities [ Time Frame: preoperative CCRT to 3 months after surgery ]

Study Completion Date: February 2012
Primary Completion Date: February 2012 (Final data collection date for primary outcome measure)
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.
