The purpose of this phase II trial was to evaluate the efficacy and toxicity of carboplatin plus paclitaxel in the treatment of advanced non-small cell lung cancer (NSCLC) previously treated with chemotherapy. Patients with a performance status (PS) of 0 or 1 who had received one or two previous chemotherapy regimens for advanced NSCLC were eligible. Paclitaxel 200mg/m(2) was infused over 3h and followed by carboplatin (area under the curve 6) infusion over 1h, once every 3 weeks. Thirty patients were enrolled. A complete response was observed in 1 patient and a partial response in 10 patients, for an overall response rate of 36.7%. The median time to progression was 5.3 months. The median survival time was 9.9 months, and the 1-year survival rate was 47%. Hematological toxicity in the form of grade 3/4 neutropenia occurred in 54%, but grade 3 febrile neutropenia developed in only 3%. Non-hematological grade 3 toxicities were less frequent. There were no treatment-related deaths. The combination of carboplatin plus paclitaxel is an active and well-tolerated regimen for the treatment of NSCLC patients who have previously been treated with chemotherapy and have a good PS.

ABSTRACT: A randomized phase II trial was conducted to determine if two non-platinum protocols are able to yield a similar efficacy and toxicity profile as compared to two platinum-based doublets in advanced non-small cell lung cancer (NSCLC). A total of 61 patients were randomly assigned to a reference regimen of carboplatin and paclitaxel (repeated every 3 weeks) or to one of three experimental regimens: paclitaxel plus vinorelbine (repeated every 3 or 4 weeks) and carboplatin plus paclitaxel (repeated every 4 weeks). The objective remission rate for all the patients was 34.1%. The median progression-free survival for all the patients was 3 months. The median overall survival and one-year overall survival were 6 months and 21.5%, respectively. Toxicity was moderate and manageable. Response, survival and toxicity did not significantly differ between the four treatment groups. The efficacy and toxicity profile of platinum-free combinations is comparable to that of platinum-based doublets.Anticancer research 01/2011; 31(1):317-23. · 1.83 Impact Factor

ABSTRACT: Background: There have been few reports on the efficacy or safety of combination therapy with carboplatin-paclitaxel plus bevacizumab(TC+Bev)in previously treatedpatients 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 andbeyondfor 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, andthen 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.Gan to kagaku ryoho.

ABSTRACT: The sole agents pemetrexed (PEM), docetaxel and anti-EGFR agents are approved second-line therapies for non-small cell lung cancer (NSCLC) after failure with cisplatin-based doublets. The potential usefulness of platinum-based doublets as rechallenge for second-line chemotherapy has not yet been established. Studies that enrolled NSCLC platinum pre-treated patients were identified using electronic databases (MEDLINE and EMBASE). Pemetrexed and taxanes (TAXs)-based platinum combinations were considered. A systematic review was conducted using Comprehensive Meta-Analysis (version 2.2.064) software to calculate the event rate of response and 95% confidence interval. Median weighted progression-free survival (PFS) and overall survival (OS) time for PEM and TAXs-based doublets were compared by two-sided Student's t test. We tested for significant heterogeneity by Cochran's chi-square test and I(2) index. Eleven studies published between 1999 and 2012 were included in this analysis with a total of 607 patients enrolled; 468 were treated with PEM-doublets and 139 with TAXs-doublets. The overall response rate was 27.5% with a higher response rate of 37.8% (range, 29.7-46.7%) for TAXs-based treatment vs. 22% (range, 13.4-34.1%) for PEM-based combinations; (p<0.0001). Median PFS and OS were 3.9 and 8.7 months with weighted PFS of 3.9 vs. 5.3 months (p<0.0001) and similar OS for PEM vs. TAXs-based doublets. With the limitations of small and not randomised trials included, this pooled analysis shows that NSCLC patients who relapsed after a first-line platinum-based chemotherapy obtain a tumour response of 27% from a platinum rechallenge containing PEM or TAXs. Response rate and median PFS appear better with TAXs-than with PEM-doublets.Lung cancer (Amsterdam, Netherlands) 07/2013; 81(3). DOI:10.1016/j.lungcan.2013.06.022 · 3.96 Impact Factor
