Abstract

Rationale:Glioblastoma (GBM) is the most aggressive malignant brain tumor in adults. The first choice for GBM is surgery, and followed by a combination of radiotherapy and chemotherapy. There are limited treatments for patients with recurrent GBM. Relapsed patients usually have a worse prognosis, and with a median survival time of <6 months. Anlotinib is a novel small molecule multi-target tyrosine kinase inhibitor that can inhibit tumor angiogenesis and inhibit tumor cell growth. This drug has been used to treat advanced lung cancer.Patient concerns:We present a case of recurrent GBM was treated with anlotinib in this report. The patient was diagnosed with GBM in August 2016 and treated with surgery and temozolomide (TMZ) chemotherapy. She was diagnosed with recurrence in February 2017 following which she was treated with gamma knife and TMZ chemotherapy. In November 2017, the patient presented with decreased vision in left eye. She was given radiation and her left eye vision returned to normal after radiation. On May23, 2018, the patient reported a decrease in left visual acuity again.Diagnoses:Brain magnetic resonance imaging (MRI) showed progression of the disease, and the tumor invaded the left optic nerve.Interventions:This patient was administer anlotinib 12 mg po qd (d1–14, 21days as a cycle). Three cycles anlotinib were given to this patient.Outcomes:The patient reported her left visual acuity increased over 10 days after first cycle of anlotinib treatment. MRI scan revealed tumor volume shrinks, especially the part that invades the left optic nerve shrinks significantly at 26 days after anlotinib treatment on August 11, 2018. However, the tumor progressed in 2 months after using of anlotinib. From the beginning of the application of anlotinib to death, her survival time was 110 days.Lessons:Anlotinib treatment with mild side effects may be a new option for the patients with recurrent glioblastoma.
