Официальное название

Adjuvant Modified FOLFOXIRI Versus mFOLFOX6 in Patients With Postoperative MRD Positive Stage II-III Colorectal Cancer: A Multicenter, Open Lable Randomized Phase 3 Study (AFFORD)

Обзор

Surgery is the main treatment method for colon cancer. About 50% of patients can be cured with surgery alone. For colon cancer with high-risk stage II or III after surgery, the current guidelines recommend 3-6 months after surgery. adjuvant chemotherapy to reduce the risk of recurrence and metastasis. However, for this part of the population, the overall benefit of adjuvant chemotherapy is limited, and different high-risk factors have different weights; some patients will still experience recurrence and metastasis even after receiving adjuvant chemotherapy. A number of previous studies have shown that patients with a positive ctDNA test on postoperative liquid biopsy without postoperative adjuvant therapy have a recurrence risk of 70-80%. Even if they receive adjuvant chemotherapy, the recurrence risk is significantly higher than that of ctDNA-negative patients. ctDNA has received increasing attention as a predictor of postoperative recurrence risk. This study intends to randomly assign 1:1 to mFOLFOXIRI regimen adjuvant chemotherapy for 6 months and mFOLFOX6 regimen for colon cancer patients with postoperative high-risk stage II-III and liquid biopsy results within 1 month after surgery. Adjuvant chemotherapy was performed for 6 months, ctDNA was dynamically monitored after 3 months of treatment and at the end of adjuvant therapy. During the follow-up period, CEA was reviewed every 3 months, and chest, abdomen, and pelvis CT and ctDNA were reviewed every 6 months; the primary endpoint of the study was 2 years RFS, secondary endpoints included 3-year DFS, OS, safety and tolerability. Through intensive postoperative adjuvant therapy, we hope to screen colon cancer patients with high recurrence risk to receive adjuvant chemotherapy and improve the survival prognosis of ctDNA-positive colon cancer patients.
