Background
We evaluated the efficacy and safety of a modified FOLFIRINOX regimen for chemotherapy-naïve patients with metastatic pancreatic cancer.
Methods
Patients with untreated metastatic pancreatic cancer (MPC) received modified FOLFIRINOX (intravenous oxaliplatin 85 mg/m2, irinotecan 150 mg/m2, 5-FU infusion 2400 mg/m2 over 46 h, no bolus 5-FU). The primary endpoints were overall survival and the incidence of grade 3 or higher neutropenia. No patients received prophylactic pegfilgrastim.
Results
Sixty-nine pts. were enrolled from 39 institutions in Japan. The median overall survival was 11.2 months [95% confidence interval (CI) 9.0–]. The median progression-free survival was 5.5 months (95% CI 4.1–6.7). The response rate was 37.7% (95% CI 26.3–50.2), and the disease control rate was 78.3% (95% CI 66.7–87.3). The incidence of grade 3 or higher neutropenia was 47.8%. Serious adverse events occurred in six patients (8.7%). All AE proportions were less than those in the previous Japanese full-dose phase II study. One patient died due to interstitial pneumonia related to treatment.
Conclusion
This is the first prospective study of modified FOLFIRINOX in Asia. Modified FOLFIRINOX in this study has an improved safety profile with maintained efficacy in MPC without prophylactic pegfilgrastim.
