Carboplatin/pemetrexed/bevacizumab in the treatment of patients with advanced non-small-cell lung cancer: a single-institution experience.
Clinical Lung Cancer 2010 May
PURPOSE: The purpose of this study was to determine the efficacy and tolerability of carboplatin, pemetrexed, and bevacizumab in patients with advanced, nonsquamous non-small-cell lung cancer (NSCLC).
PATIENTS AND METHODS: The charts of consecutive patients with stage IIIB/IV nonsquamous NSCLC were reviewed. All patients receiving at least 1 cycle of the 3-drug regimen (pemetrexed 500 mg/m2, carboplatin area under the curve of 5-6, bevacizumab 15 mg/kg intravenously), were included for assessment of response, safety, and toxicity.
RESULTS: A total of 27 patients received this regimen between February 2008 and July 2009; 63% were women. Median follow-up was 6.3 months (range, 1.6-21.1 months). Median number of cycles was 6 (range, 1-6 cycles); 67% completed 6 cycles; 83% went on to receive maintenance bevacizumab/pemetrexed. Among those who received maintenance, the median number of cycles administered was 4.5 (range, 1-18 cycles). Response rate was 52%; stable disease was observed in another 40%. On the basis of Kaplan-Meier analysis, actuarial overall survival was 83% at 12 months; actuarial progression-free survival was 83% and 63% at 6 and 12 months, respectively. Clinical improvement was noted in 41% of the patients, with clinical stability in another 48%. Grade 2 and 3 toxicities from the regimen included anemia (11% and 15%), fatigue (37% and 7.4%), febrile neutropenia (7.4%; grade 3 only), thrombocytopenia (7.4% and 0), and thromboembolic disorders (3.7% and 3.7%). Bevacizumab-induced side effects (any grade) included headaches (22.2%), epistaxis (30%), hemoptysis (3.7%), and hypertension (11%). No grade 4 or 5 toxicities were seen.
CONCLUSION: Combination carboplatin/pemetrexed and bevacizumab followed by maintenance therapy with pemetrexed/bevacizumab is effective, with response rates > 50%, acceptable toxicity, and promising early survival in patients with advanced nonsquamous NSCLC.
