Overview

abstract

  • The aim of the present study was to retrospectively evaluate the feasibility of cisplatin/pemetrexed/bevacizumab (CPB) therapy at a bevacizumab (BEV) dose of 15 mg/kg as a first-line chemotherapeutic strategy for patients with advanced non-squamous non-small cell lung cancer (NSCLC). A total of 31 consecutive patients with non-squamous NSCLC were treated with first-line chemotherapy of CPB at a BEV dose of 15 mg/kg at the National Kyushu Cancer Center (Fukuoka, Japan) between November 2009 and December 2011. Clinical characteristics, response rate (RR), progression-free survival (PFS) time, overall survival (OS) time and adverse events were retrospectively analyzed. The 31 patients exhibited a male:female ratio of 21:10 and a median age of 60 years (range, 38-76 years). In total, 5 patients were of clinical stage III and 26 patients were of stage IV, 15 had a performance status of 0 and 16 had a performance status of 1, and 29 patients were diagnosed with adenocarcinoma and 2 were diagnosed with adenosquamous carcinoma. The EGFR mutation status was positive (exon 19 deletion), wild-type and unknown in 3, 21 and 7 patients, respectively. A total of 28 patients (90.3%) received a minimum of four courses of CPB therapy. Hematological toxicities classified as grade III or higher included neutropenia (29.0%), anemia (3.2%) and thrombocytopenia (3.2%), however, no severe non-hematological toxicities were observed. Additionally, 22 patients (71.0%) exhibited a partial response and 9 (29.0%) exhibited stable disease, resulting in a RR of 71.0% [95% confidence interval (CI), 41-74]. The median PFS and OS times were 8.4 months (95% CI, 7.9-9.0) and 28.5 months (95% CI, 26.4-30.6), respectively. Therefore, CPB therapy at a BEV dose of 15 mg/kg appears to be a feasible treatment strategy for patients with advanced non-squamous NSCLC.
