mFOLFIRINOX versus mFOLFOX as additional treatment for high-risk stage III colon cancer
mFOLFIRINOX Versus mFOLFOX 6 as Adjuvant Treatment for High Risk Stage III (pT4N1/2 or pTanyN2) Colon Cancer: Multicenter, Open Labeled, Randomized, Phase II Study
This trial will test whether giving mFOLFIRINOX instead of mFOLFOX after surgery helps people with high-risk stage III colon cancer (pT4N1/2 or any pT with N2) stay cancer-free longer.

What this trial studies
This is a multicenter, open-label, randomized phase II/III trial that assigns patients 1:1 to receive either mFOLFIRINOX or mFOLFOX6 after curative (R0) resection. Eligible patients must have high-risk stage III colon adenocarcinoma (pT4N1 or pTanyN2) and meet age, performance status, and organ function requirements. Treatment begins within 60 days after surgery and patients are followed for outcomes such as recurrence and survival while monitored for toxicity. The trial compares a more intensive chemotherapy combination (mFOLFIRINOX) against the current mFOLFOX6 backbone to see if intensification reduces relapse in this higher-risk group.
Who should consider this trial
Good fit: Ideal candidates are adults aged 20–75 with pathologically confirmed high-risk stage III colon cancer (pT4N1 or pTanyN2) who had an R0 resection within 60 days, meet ECOG and organ function criteria, and can give informed consent.
Not a fit: Patients with distant metastases, rectal cancer requiring radiotherapy, major postoperative complications, poor organ function, or an ECOG performance status beyond the allowed limits are unlikely to benefit from or be eligible for this protocol.
Why it matters
Potential benefit: If successful, the intensified mFOLFIRINOX regimen could lower recurrence rates and improve disease-free survival for patients with high-risk stage III colon cancer.
How similar studies have performed: Intensified chemotherapy regimens have been explored in other settings but using FOLFIRINOX-like combinations as adjuvant therapy for high-risk stage III colon cancer is relatively novel with limited prior data and a known trade-off between potential benefit and increased toxicity.
