Objective: To observe the role of cerebrospinal fluid (CSF) TP53 gene mutation in lung cancer associated meningitis. Methods: A retrospective analysis was performed on 35 patients diagnosed with lung cancer associated meningitis at the Second Hospital of Hebei Medical University from December 2015 to December 2018.All patients underwent the next-generation sequencing of CSF, and TP53 gene was found to be mutant or wild type, including 23 patients with TP53 mutant type and 12 patients with TP53 wild type. The clinical characteristics, CSF leukocyte, protein, glucose, chloride, Karnofsky performance (KPS) and overall survival were observed. Results: Headache, nausea and vomiting were the main clinical manifestations in both groups.There were no significant differences in CSF pressure, leukocyte, biochemical indicators and KPS between the two groups. The average time from diagnosis of lung cancer to diagnosis of lung cancer associated meningitis in the TP53 mutant group was significantly shorter than that in the TP53 wild type group (5.79 months vs 25.5 months).The median survival time of patients in the TP53 mutant group from lung cancer diagnosis to the observation endpoint was 19.77 months, while it was 88.73 months in the TP53...Continue Reading
