ABSTRACT
BACKGROUND:
We hypothesized that the combination of bevacizumab, carboplatin, and pemetrexed will be an effective first-line regimen in fit, elderly patients with nonsquamous non-small-cell lung cancer.METHODS:
Treatment-naïve, stage IIIB/IV nonsquamous non-small-cell lung cancer patients more than 70 years old with good performance status (Eastern Cooperative Oncology Group performance status 0-1) and adequate organ function were eligible. Carboplatin area under the curve 6, pemetrexed 500 mg/m, and bevacizumab 15 mg/kg were administered on day 1 of each 21-day cycle (up to six cycles) followed by maintenance pemetrexed and bevacizumab. The primary end point of 6-month progression-free survival rate of at least 70% was assessed using a one-stage binomial design. Quality of life (QOL) questionnaires were administered. Polymorphisms in genes encoding relevant proteins (drug targets, transport, and metabolism proteins) were correlated with treatment outcome.RESULTS:
Fifty-seven eligible patients were enrolled. Median age was 74.5 years. Median treatment cycles received was 6. The most common grade 3 or higher non-hematologic adverse events were fatigue (26%) and hypertension (11%); 16% had grade 4 neutropenia and 6.5% had grade 4 thrombocytopenia. Three patients experienced grade 3/4 hemorrhagic events (one pulmonary, two gastrointestinal). Primary end point of PFS6 was 60% (95% confidence interval [CI] 45.9-73%). Median PFS was 7.0 months (95% CI 5.9-10.1), median overall survival was 13.7 months (95% CI 9.4-16.8). Polymorphic KDR and VEGFA variants correlated with survival and toxicity, respectively. There was no significant change in overall QOL scores over time.CONCLUSION:
This regimen is feasible and did not decrease the QOL in this study population. However, it did not meet the primary efficacy end point.
