The Evaluation of Durative Transfusion of Endostar Combined with Chemotherapy in Patients with Advanced Non-Small Cell Lung Cancer

Abstract

BACKGROUND: The overall survival (OS) in non-small cell lung cancer (NSCLC) is poor, with median OS of advanced NSCLC with standard systemic chemotherapy being reported at 13.6 months and the 5-year survival rate at less than 15%. Therefore, the aim of this study was to evaluate Endostar combined with chemotherapy in patients with advanced NSCLC. METHODS: Data on 116 cases of pathologically confirmed stage IIIB-IV NSCLC were retrospectively collected. The control group was treated with chemotherapy combined with intravenous infusion of Endostar while the test group received durative transfusion of Endostar. The short-term therapeutic effects including overall response rate (ORR), disease control rate (DCR), and safety were evaluated in both groups. In the follow-up, progression-free survival (PFS) and OS were also analysed. RESULTS: In the test group, the ORR was 53.4%, which was similar to that in the control group (44.8%) (p > 0.05). However, the DCR in the test group (86.2%) was significantly higher than that in the control group (70.7%) (p < 0.01). The median time to progression in the test group (6 months) was also significantly longer than that in the control group (4 months). Importantly, the median OS in the test group (17.5 months) was improved compared to the control group (13.5 months). The 1-year survival rate in the test and control groups was 9.7 and 15.8%, respectively. There was no significant difference in side effects (including thrombocytopenia, leucopenia, nausea, and vomiting) between the two groups. CONCLUSIONS: Endostar durative transfusion combined with chemotherapy showed a higher DCR, longer PFS and OS time, and was well tolerated in patients with advanced NSCLC.
