Abstract:
Background and objective Leptomeningeal carcinomatosis is a rare type of metastatic tumors of the central nervous system. In recent years, with the improvement of neoplasms therapies and longer survival of patients by better systemic control, incidence of leptomeningeal metastases has increased every year. However, there is still lack of effective thera-pies. hTe aim of this study is to investigate the effcacy, security and prognosis of intrathecal chemotherapy with methotrexate (MTX) in the treatment of neoplastic meningitis.Methods A total of 27 patients were enrolled. We investigated clinical fea-tures and cerebrospinal lfuid (CSF) examination results retrospectively, and analyzed the adverse reactions as well as prognosis atfer intrathecal chemotherapy.Results All 27 patients were treated by intrathecal MTX, 70.4% had clinical remission, how-ever, there was no signiifcant difference in CSF pressure and CSF biochemical changes. We observed that 55.6% patients were all appropriate, 25.9% appeared lower limb numbness and mild pain, no serious irreversible adverse reactions occurred. Median overall survival was 4 months.Conclusion We suggest that intrathecal administration of MTX is associated with improvement of symptoms of leptomeningeal metastasis patients and no severe adverse events observed.
