Study Arms (2)

4xCapOx

EXPERIMENTAL

Patients will receive 4 cycles of neoadjuvant CapOx chemotherapy (oxaliplatin 130 mg/m2 iv day 1, capecitabine 2000 mg/m2 bid per os days 1-14 every 3 weeks). In case of partial response or stable disease (based on pelvic MRI) patients proceed to surgery. In case of disease progression patients receive 50 Gy pelvic chemoradiotherapy with capecitabine 825 mg/m2 bid per os on radiation days and then surgery. The decision to proceed with adjuvant chemotherapy postoperatively will be based on pTNM stage

Surgery

ACTIVE COMPARATOR

Patients will receive standard surgery for rectal cancer with partial or total mesorectal excision (based on exact tumor location and surgeons discretion). The decision to proceed with adjuvant chemotherapy postoperatively will be based on pTNM stage
