[A case of meningeal carcinomatosis from lung cancer successfully treated with aggressive multimodal therapy].

ABSTRACT

A 44-year-old man was admitted to our hospital because of brain metastasis and intrapulmonary exacerbation of lung adenocarcinoma. Systemic chemotherapy (PAC + CBDCA) was administered, but neurological symptoms (muscle weakness of limbs and disorientation) appeared. Lumbar puncture and enhanced MRI of lumber vertebrae revealed meningeal carcinomatosis. MTX 20 mg/week (+ Ara-C 40 mg/week) was injected into the meningeal space. There was a clear improvement in the neurological symptoms, but it did not last long. Meningeal injection was performed 7 times. Whole-brain and whole-marrow radiation along with systemic chemotherapy gave a marked improvement in the symptoms and in the metastatic shadow on the chest CT scan.
