Summary

BACKGROUND:

In patients with high risk stage II and stage III colon cancer (CC), curative surgery followed by adjuvant chemotherapy with FOLFOX or CAPOX regimens has become a standard treatment. However, 20 to 30 % of these patients will develop distant metastasis, which ultimately result in death. Perioperative chemotherapy is a promising strategy with potential benefits that could be more effective at eradicating micrometastases. Moreover, shrinking tumor before surgery not only facilitate removal of all the tumor by the surgeon but also reduce tumor cell spreading during the procedure. With recent advances in radiology, preoperative computed tomography allows a good prediction of tumor stage (wall penetration and nodal involvement) prior to surgery. The investigators conducted the present randomized study to explore whether perioperative chemotherapy with FOLFOXIRI regimen compared with postoperative chemotherapy could improve disease-free survival in patients with radiologically staged, High-risk, but resectable Stage II or III colon cancer.

OBJECTIVE:

The primary objective of this study is to evaluate the efficacy of perioperative chemotherapy with FOLFOXIRI regimen compared to postoperative chemotherapy in patients with High-risk Resectable Stage II and III colon cancer. Secondary objectives are efficacy in terms of R0 resection rate, overall survival (OS), relapse-free survival (RFS), down-staging of primary tumors, and tolerability of perioperative therapy and postoperative complications.

Conditions

  • Colon Cancer Stage II
  • Colon Cancer Stage III

Interventions

DRUG

neoadjuvant chemotherapyI

mFOLFOXIRI (IV oxaliplatin given over 120 min at a dose of 85 mg/m2 on day 1 followed by IV leucovorin 400 mg/m2 over 2h, IV Irinotecan 150 mg/m2 and IV infusional 5-Fluorouracil 2400 mg/m2 over 48h every 14 days) for 6 cycles followed by colectomy (3 to 6 weeks after) . If PD was observed after 3 cycles, direct colectomy was performed.

PROCEDURE

Colectomy

Radical colectomy

DRUG

adjuvant chemotherapy

mFOLFOX6 (IV oxaliplatin given over 120 min at a dose of 85 mg/m2 on day 1 followed by IV leucovorin 400 mg/m2 over 2h, IV bolus 5-Fluorouracil 400 mg/m2 and IV infusional 5-Fluorouracil 2400 mg/m2 over 46h every 14 days) . CAPOX (IV oxaliplatin given over 120 min at a dose of 130 mg/m2 on day 1, oral capecitabine 1000 mg/m2 twice daily on days 1 through 14 every 21 days) . Oral capecitabine 1000 mg/m2 twice daily on days 1 through 14 every 21 days. The plan and cycles are determined according to the surgical pathology and physical conditions.
