Experimental: chemoradiation followed by CapOx
preoperative chemoradiation 50.4Gy with capecitabine or 5-fluorouracil/leucovorin (pelvic radiation capecitabine 5-fluorouracil) followed by 2 cycles of chemotherapy (Capecitabine Oxaliplatin - CapOx) and surgery (total mesorectal excision)
|
after completion of chemoradiation, two cycles of capecitabine (850mg/m2 twice daily from D1 evening to D15 morning) and oxaliplatin (100mg/m2 on D1) will be administered every 3 weeks.
