Abstract

Introduction

Oral tegafur/uracil and leucovorin (UFT/LV) therapy is effective and safe for elderly patients with advanced or metastatic colorectal cancer (CRC). However, there have been few studies on the combination of bevacizumab with UFT/LV. This clinical study is aimed to evaluate the efficacy and safety of UFT/LV plus bevacizumab as a first line therapy for elderly patients with advanced or metastatic CRC.

Methods

Forty patients with advanced or metastatic CRC aged ≥75 years were enrolled in this multicenter, open-label, single arm phase II study. All patients received oral tegafur/uracil (300–600 mg) and leucovorin (50 mg) twice daily on days 1–21, and intravenous bevacizumab (5 mg/kg) on days 1 and 15 of a 4-week cycle. (UMIN000003447)

Results

The median follow-up period was 14.7 months. The response rate was 20.0% (95% confidence interval [CI]: 9.1–35.6%), median progression-free survival was 8.9 months (95% CI: 5.3–11 months), and median overall survival was 21.7 months (95% CI: 13.7–23.4 months). The grade-3 hematological toxicity included just neutropenia (3.0%), and the incidences of grade-3 non-hematological toxicity were less than 10%.

Conclusion

UFT/LV plus bevacizumab was a promising first-line regimen for elderly patients with advanced or metastatic CRC. This combination therapy was well tolerated and efficacious.
