BACKGROUND: The aim of this trial was to determine feasibility of incorporating bevacizumab (B) into concurrent chemoradiotherapy (CRT) for locally advanced non-small-cell lung cancer (NSCLC).
PATIENTS AND METHODS: Patients with unresectable stage III NSCLC, performance status of 0 to 1, and adequate organ function were accrued in 2 strata, low- and high-risk (squamous histology, hemoptysis, tumor with cavitation and/or adjacent to a major vessel). Cohort 1 patients received cisplatin 50 mg/m(2) days (d) 1 and 8, etoposide 50 mg/m(2) (d 1-5) for 2 cycles concurrent with radiotherapy (64.8 Gy) followed by docetaxel (D) 75 mg/m(2) and B 15 mg/kg for 3 cycles. If safety was established, then accrual would continue to cohort 2 (B, d 15, 36, 57) and then subsequently to cohort 3 (B, d 1, 22, 43).
RESULTS: Twenty-nine patients (17 low- and 12 high-risk) registered to cohort 1. Twenty-six patients (including 4 squamous, 1 adenosquamous) were assessable. Twenty-five completed CRT. Grade 3/4 toxicities during CRT included acceptable rates of hematologic toxicity, esophagitis, and pneumonitis. Of 21 assessable for safety with D/B consolidation, major adverse events were pneumonitis (2 Grade 3) and 2 episodes of fatal hemoptysis in the high-risk group, resulting in closure of this stratum. The low-risk stratum subsequently closed because of slow accrual. Median overall survival was 46 months for low-risk and 17 months for high-risk strata.
CONCLUSION: Bevacizumab was not safely integrated into CRT for stage III NSCLC in patients considered at high risk for hemoptysis. In lower risk patients, data are insufficient to determine safety or efficacy.
