    Abstract:
    Six patients (2.7%) developed meningeal carcinomatosis among 207 patients with small cell lung cancer (SCLC) receiving intensive combination chemotherapy. The cumulative probability of developing meningeal carcinomatosis was 2.7% at 3 years and 7.8% at 5 years after diagnosis of SCLC. Pain in legs, gait disturbance, headache, nausea and vomiting were the characteristic symptoms at the onset of meningeal carcinomatosis. Although cytological examination of cerebro-spinal fluid (CSF) was essential for the diagnosis of meningeal carcinomatosis, elevated protein, LDH, CEA and/or NSE concentration and decreased glucose concentration in CSF were also helpful for the diagnosis. For treatment of meningeal carcinomatosis, all patients received intrathecal administration of methotrexate, cytosine arabinoside and/or prednisolone. Additionally, 3 patients received spinal irradiation, and one received cerebro-spinal irradiation. However, only 2 patients responded, and survival was brief ranging from 2 to 38 weeks. Development of meningeal carcinomatosis seems to be a rare event; however, it may be an obstacle to the prolongation of patient survival in the treatment of SCLC.
