Abstract
Abstract BACKGROUND Pediatric low-grade gliomas (pLGGs) entail highly effective treatment regimens. In this study, we aimed to examine the efficacy and safety of recombinant human endostatin (rh-ES) combined with chemotherapy for pLGGs. METHODS We collected the clinical data of pLGG patients treated with carboplatin and vincristine (CV) plus rh-ES in the Department of Neuro-oncology, Sanbo Brain Hospital Capital Medical University, Beijing, China, from July 2015 to October 2019 and retrospectively analyzed the effectiveness and safety of this regimen. RESULTS A total of 41 eligible patients were enrolled. Median age at diagnosis was 4 years. Median follow-up lasted for 22.7 months (range 8-73.4 months). Six patients achieved complete response, 7 attained partial response, 4 had minor response, the disease was stable in 3 cases, and in 1 the condition progressed. The objective response rate was 90.2% and complete response rate was 14.6%. The median time to response was 4.1 months. The duration of response was 28.1 months. The progression rate within 6 months of treatment completion was 6.9%. 5-year rates were 74% for progression-free survival and 92% for overall survival. The main toxicities included myelosuppression and carboplatin allergy. No serious rh-ES-related toxicities were observed. CONCLUSIONS Rh-ES in combination with CV in pLGG patients was effective and safe and could achieve rapid and lasting responses.
