The study was able to show that the cumulative 5-year survival rate was 75% for patients with a pCR (HR=1) as compared with 57% for patients with a major response (HR=4.91) and only 13% for patients with a minor or no response (HR=13.46) (p=0.01). Overall, approximately 30% of patients were considered to be responders to neoadjuvant chemotherapy (9.7% pCR + 20.2% major response), while about 70% of patients were considered non-responders to treatment. Treatment consisted of a FOLFOX- or FOLFIRI-based regimen in the majority of patients.
