Case Report: Targeted Therapy with Anlotinib for a Rare Case of Spinal Cord Glioblastoma with FGFR3 Mutation

Abstract

Primary spinal cord glioblastoma (PSC GBM) is a rare disease with limited treatment options. Here, we describe a case of PSC GBM treated with anlotinib in this report. Molecular characterization confirmed the presence of the MGMT promoter unmethylated, IDH wild type, FGFR3 p.S249C and p53 p.V73fs mutations in the patient. Anlotinib is a multitarget tyrosine kinase inhibitor that target VEGFR2/3, FGFR1-4, PDGFRα/β, and c-kit. After a partial resection of the tumor at the extramedullary invasion site, the patient was administered anlotinib 12 mg p.o. once every day (days 1–14, 21-day cycle) in combination with irinotecan chemotherapy (days 1 and 8, 21-day cycle). The patient exhibited significant symptom remission and partial response and was maintained for more than 10 months of follow-up. This case study showed that FGFR3 S249C may be a new marker for the treatment of PSC GBM with anlotinib. This case is also another strong support for molecular diagnosis and precision medicine.
