      Background:
      Endostatin inhibits the pro-angiogenic action of basic fibroblast growth factor and vascular endothelial growth factor in different human cancers. This study assessed the efficacy of endostatin combined with concurrent chemoradiotherapy of non-small cell lung cancer (NSCLC).

      Methods:
      Nineteen patients with unresectable stage III NSCLC, ECOG performance status 0-l, and adequate organ function were treated with 60–66 Gy thoracic radiation therapy over 30–33 fractions concurrent with weekly 7.5 mg/m[2] endostatin for 14 days, 50 mg/m[2] paclitaxel, and 2 mg/mL/min carboplatin over 30 min. Patients were then treated with 7.5 mg/m[2] endostatin for 14 days, 150 mg/m[2] paclitaxel, and 5 mg/mL/min carboplatin every 3 weeks for 2 cycles as the consolidation treatment (Fig.1). The objective response rate was recorded according to the RECIST criteria, and the toxicity was evaluated using the NCI Common Toxicity Criteria. Figure 1



      Results:
      Six patients were unable to complete the consolidation treatment (4 pulmonary toxicity, 1 tracheoesophageal fistulae, and 1 progressive disease). Seventeen patients were included for data analysis. Specifically, one (5.9%) patient had a complete response and 13 (70.6%) had a partial response, whereas two patients had stable disease and the other two had disease progression. The overall response rate was 76% [95% CI, 51%–97%]. The median progression-free survival was 10 months (95% CI, 7.6–12.3 months), and the median overall survival was 14 months (95% CI, 10.7–17.2 months) (Tab.1). The toxicity analysis of 10 patients who completed the treatment regimen showed that four patients experienced grade III pulmonary toxicity. Figure 1



      Conclusion:
      The results demonstrated no evidence of the efficacy of endostatin concurrent with chemoradiotherapy of locally advanced unresectable NSCLC. The real impact of endostatin as the first-line treatment combined with chemoradiotherapy on the survival of NSCLC patients remains to be determined.
