To investigate the efficacy and safety of recombinant human endostatin(Endostar)combined with platium-contained chemotherapeutic agents in advanced non-small cell lung cancer(NSCLC)patients over 60 years old.

93 advanced NSCLC patients from January 2019 to June 2021 were selected as the research objects.The patients received three days of continuous intravenous infusion of Endostar(210 mg for 72 hours)combined with platinum-containing chemotherapy.The efficacy and toxicities were evaluated according to Response Evaluation Criteria in Solid Tumors(RECIST)version1.1 and National Cancer Institute Common Terminology Criteria for Adverse Events(NCI-CTCAE version 4.0), respectively.Follow-up data were obtained to perform the Kaplan-Meier survival analysis.

In our study, the objective remission rate(ORR)and disease control rate(DCR)were 38.7% and 78.5%, respectively.The median progression-free survival(PFS)and overall survival(OS)were 6.8 months and 16.5 months, respectively.A Multivariate analysis showed that tumor staging and TP53 mutation were independent prognostic factors related to PFS and OS in advanced NSCLC patients.Adverse reactions related to Endostar during treatment included arrhythmia in 2 cases(2.2%), myocardial ischemia in 1 case(1.07%)and bloody sputum in 1 case(1.07%), all of which were Grade 1 or Grade 2.

The application of three days continuous intravenous infusion of Endostar combined with platium-contained chemotherapeutic agents is worthy to be recommended for clinical application in elderly patients with advanced NSCLC due to its high effective rate and survival advantage, as well as good safety.
