Clinical characteristics and prognostic factors in nasopharyngeal carcinoma with brain metastasis: A retrospective, single-center study.

Abstract

Brain metastasis is rare in nasopharyngeal carcinoma (NPC), with only anecdotal cases reported. Conducting a systematic study is crucial for improving the management of these patients. Forty-one patients with brain metastasis were retrospectively included between February 2000 and February 2023. The clinical characteristics and treatment information of patients were analyzed. Overall survival (OS) was estimated by Kaplan-Meier survival analysis, and Cox proportional hazard regression analysis was performed to explore prognostic factors. The median OS for patients was 11.2 months, with a 3-year OS rate of 16.3%. The number of extracranial metastatic organs (HR = 5.533, P = 0.041) and the response of extracranial tumors to treatment (HR = 0.079, P = 0.003) were independent prognostic factors in the cohort. Brain metastasis in NPC is a devastating condition that commonly occurs through hematogenous dissemination. Systemic therapy remains fundamental treatment, while local therapy for brain metastases may further improve survival in selected patients.
