Study Summary

This phase II trial compares the effect of irinotecan versus oxaliplatin after long-course chemoradiation in patients with stage II-III rectal cancer. Combination chemotherapy drugs, such as FOLFIRINOX (fluorouracil, irinotecan, leucovorin, and oxaliplatin), FOLFOX (leucovorin, fluorouracil, oxaliplatin, and irinotecan ), and CAPOX (capecitabin and oxaliplatin) work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. FOLFOX or CAPOX are used after chemoradiation as usual treatment for rectal cancer. Giving FOLFIRINOX after chemoradiation may increase the response rate and lead to higher rates of clinical complete response (with a chance of avoiding surgery) compared to FOLFOX or CAPOX after chemoradiation in patients with locally advanced rectal cancer.

Primary Outcome

Defined as the number of patients who achieved cCR at the end of total neoadjuvant therapy (TNT) divided by number of patients included in the analysis population. This endpoint will be assessed within 8-12 weeks after completion of TNT. If there is a cCR, then the patient will be counted in the numerator. If there is a near-complete response (nCR) then a re-evaluation within 4-8 weeks will be performed. If an nCR evolved to a cCR, then the patient will be counted in the numerator. Otherwise, th
