    Abstract:
    PURPOSE: Bevacizumab and erlotinib have been shown to improve survival in stage IV non-small-cell lung cancer (NSCLC). This phase I/II trial was designed to incorporate these agents with induction and concurrent chemoradiotherapy in stage III NSCLC. PATIENTS AND METHODS: Patients received induction chemotherapy (carboplatin area under the curve [AUC] 6, paclitaxel 225 mg/m(2), and bevacizumab 15 mg/kg on days 1 and 22) followed by concurrent chemotherapy (carboplatin AUC 2 and paclitaxel 45 mg/m(2) weekly with bevacizumab 10 mg/kg every other week for four doses) and thoracic conformal radiation therapy (TCRT) to 74 Gy. In the phase I portion, cohort 1 received no erlotinib, whereas cohorts 2 and 3 received erlotinib at 100 and 150 mg, respectively, Tuesday through Friday, during TCRT. Consolidation therapy with erlotinib (150 mg daily) and bevacizumab (15 mg/kg every 3 weeks) was planned 3 to 6 weeks later for six cycles. RESULTS: Forty-five eligible patients were enrolled. The objective response rates to induction and overall treatment were 39% (95% CI, 24% to 55%) and 60% (95% CI, 44% to 75%), respectively. The median progression-free and overall survival times were 10.2 months (95% CI, 8.4 to 18.3 months) and 18.4 months (95% CI, 13.4 to 31.7 months), respectively. The principal toxicity was esophagitis (29% grade 3 or 4 esophagitis, with one patient with grade 3 tracheoesophageal fistula), which was often prolonged. Consolidation therapy with bevacizumab and erlotinib was not feasible. CONCLUSION: The use of bevacizumab and erlotinib as administered in this trial is not recommended given the lack of an efficacy signal and the substantial risk of esophageal toxicity.
