What this trial studies

This clinical trial investigates the effectiveness and safety of two different adjuvant chemotherapy regimens, mFOLFOXIRI and mFOLFOX6/CapeOx, in patients who have undergone surgery for stage IIIB or IIIC colorectal cancer. Postoperative patients will be randomly assigned to receive one of the two treatments for six months, with the option to switch regimens if they experience intolerable side effects. The study aims to evaluate disease-free survival, overall survival, and quality of life, as well as the incidence of adverse reactions associated with the chemotherapy. The trial is designed as a two-arm, open-label, prospective, randomized phase II study.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 who have undergone curative surgery for stage IIIB or IIIC colorectal cancer without distant metastasis.

Not a fit: Patients with prior chemotherapy or radiotherapy, significant cardiovascular disease, or other concurrent cancers may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective chemotherapy option for patients with advanced colorectal cancer, potentially improving survival rates and quality of life.

How similar studies have performed: While there have been studies comparing various chemotherapy regimens for colorectal cancer, the specific comparison of mFOLFOXIRI to mFOLFOX6/CapeOx in this postoperative setting is relatively novel.
