Background: There have been few reports on the efficacy or safety of combination therapy with carboplatin-paclitaxel plus bevacizumab(TC+Bev)in previously treated patients with non-small cell lung carcinoma(NSCLC).
Purpose: The objective of this study was to assess the efficacy and safety of TC+Bev as second-line therapy and beyond for previously treated NSCLC patients.
Methods: A total of 17 patients previously treated with NSCLC at the Kitasato University Hospital between April 2010 and February 2012 were enrolled in this retrospective study. On day 1 all patients received a 200mg/m2 dose of paclitaxel by intravenous infusion over a 3-h period, followed by infusion of carboplatin at a dose corresponding to an AUC of 6.0 min mg/mL, and then by Bev at a dose of 15mg/m2. The treatment course was repeated every three or four weeks. Patients continued to receive Bev monotherapy every 3 weeks thereafter until evidence of disease progression or unacceptable toxicity developed.
Results: Median age: 60 years old(range 39-74 years old); gender: male/female, 6/11; PS 0-1/≥2, 17/0; clinical stage:III B/IV postoperative recurrence, 0/16/1; EGFR mutation status: positive/negative/unknown, 7/9/1; histological type: adenocarcinoma in all patients; median number of prior regimens: 3. 4(1-6); median number of cycles(induction phase): 3(1-6). The objective response rate and disease control rate were 17. 6% and 70. 6%, respectively, and the median progression-free survival time was 4. 7 months. There were no treatment-related deaths, and the toxicities of the treatment regimen were acceptable.
Conclusion: TC+Bev therapy exhibits activity in previously treated NSCLC patients and has acceptable toxicity. Further study is warranted to confirm our results.
