Background: This study was designed to evaluate the efficacy and safety of XELOX plus bevacizumab in a Japanese metastatic colorectal cancer population that included elderly patients. Methods: This was a multicenter, single-arm, open-label prospective study. The major inclusion criteria were previously untreated metastatic colorectal cancer, presence of measurable lesions, age ≥20 years; Eastern Cooperative Oncology Group performance status of 0–2, and adequate organ function. Patients received bevacizumab (7.5 mg/kg on day 1) and XELOX (130 mg/m2 oxaliplatin on day 1 plus 1,000 mg/m2 capecitabine b.i.d. on days 1–14) every 3 weeks. The primary endpoint was confirmed objective response rate. Results: The study included 47 patients (male/female 30/17; median age 69 years; age range 38–81 years with 10 patients ≥75 years; PS 0/1/2, 40/5/2) enrolled between May 2010 and March 2011. Responses were assessed in 46 eligible patients. The objective response rate was 52.2 % (95 % confidence interval [CI] 37.0–67.1). The median progression-free survival and overall survival were 10.0 months (95 % CI 7.8–12.3) and 34.6 months (95 % CI 19.9–not estimable), respectively. Frequently encountered grade 3 and 4 adverse events in this study were aspartate aminotransferase elevation (23.4 %), alanine aminotransferase elevation (21.3 %), anorexia (12.8 %), neutropenia (10.6 %), fatigue (8.5 %) and anemia (6.4 %). Grade 3 or 4 peripheral neuropathy was not observed. Conclusion: First-line treatment with XELOX plus bevacizumab showed a promising response rate and an acceptable tolerability profile in the clinical practice of Japanese metastatic colorectal cancer patients that included elderly patients.
