Recombinant human endostatin combined with concurrent chemoradiotherapy in treatment of locally advanced non-small cell lung cancer

Objective To evaluate the efficacy and safety of docetaxel and cisplatin （DP） concurrent chemoradiotherapy combined with recombinant human endostatin （endostar） in patients with inoperable locally advanced non-small-cell lung cancer （LANSCLC）. Methods A total of 28 patients diagnosed with inoperable LANSCLC （ⅢA or Ⅲ B） were randomly divided into two groups . Patients of the experimental group（n = 14） were treated with endostar combined DP chemotherapy （docetaxel 75 mg/m2 on day 1, cisplatin 20 mg/m2 on day 1 -4 and endostar 15 mg/d on day 1 - 14 ,repeated every 3 -4 weeks and with 3 to 4 cycles） and concurrent thoracic radiotherapy while the patients of the control group（ n = 14） were treated with DP concurrent chemoradiotherapy only. The primary tumors and involved lymph nodes wereadministrated three-dimensional conformal radiotherapy （3DCRT） at a total dose of 50 to 60 Gy （200 cGy! fraction ,51Yweek, completed in 5 to 6 weeks） to all patients. After 4 -6 weeks patients with residual tumor lesions received additional stereotactic body radiotherapy（SBRT） at the doses of 18 -27 Gy （300 cGy/ fraction, every other day） not beyond the tolerated doses of surrounding important normal organs. The efficacy was evaluated according to RECIST criteria. The adverse reactions were evaluated according to NCI CTC3.0 criteria and RTOG/EORT radiation reaction criteria. Results The response rate （ CR ＋ PR） was 71.4% in the experimental group and 64.3% in control group after 3DCRT（P 〉 O. 05）. Though the overall response rate raised after SBRT in both groups （85.71% vs 78.57% ）, the diversities were not significant（P 〉 0. 05 ）. Till last follow-up day, time to progression （TIP） and 1-year progression free survival rate and 1-year overall survival rate and median survival time （MST） in experimental group myelosuppression and control group were 13.0 m vs 11.8 m,64.3% vs 57.1% ,78.6% vs 85.7% and 21.1 m vsl9.8 m respectively without significant difference （P 〉 0.05 ）. The main adverse reactions of both groups include , nausea and vomiting, grade 1 to 2 acute radiation pneumonitis and acute radiation esophagitis （ P 〉 0. 05 ）. Though the experimental group patients were observed with more transient cardiovascular adverse reactions ,the diversities were not significant（ P 〉 0.05 ）. All the adverse reactions could be relieved and tolerated after appropriate treatment. Both group patients were not observed with hemorrhage,grade g hematoblast depression, grade 3 to 4 acute radiation pneumonitis and acute radiation esophagitis. Conclusion The concurrent chemoradiotherapy （based on 3DCRT） of docetaxel and cisplatin combined with recombinant human endostatin （endostar） can be considered as an effective and feasible approach for the treatment of chosen inoperable LANSCLC.
