PurposeThe objective of this study was to evaluate the efficacy and safety of Endostar combined with concurrent chemoradiotherapy (CCRT) in patients with stage III non-small-cell lung cancer (NSCLC). MethodsPatients with unresectable stage III NSCLC were treated with Endostar (7.5mg/m2/d) for 7days at weeks 1, 3, 5, and 7, while two cycles of docetaxel (65mg/m2) and cisplatin (65mg/m2) were administered on days 8 and 36, with concurrent thoracic radiation to a dose of 60–66Gy. Primary end points were short-term efficacy and treatment-related toxicity. ResultsFifty patients were enrolled into the study, and 48 were assessable. Of the 48 patients, 83% had stage IIIB and 65% had N3 disease. Median follow-up was 25.0months. Overall response rate was 77%. The estimated median progression-free survival (PFS) was 9.9months, and the estimated median overall survival (OS) was 24.0months. The 1-, 2-, and 3-year local control rates were 75%, 67%, and 51%, PFS rates were 48%, 27%, and 16%, and OS rates were 81%, 50%, and 30%, respectively. All toxicities were tolerable with proper treatment. ConclusionsThe combination of Endostar with CCRT for locally advanced NSCLC patients was feasible and showed promising survival and local control rates.
