Purpose: Leptomeningeal carcinomatosis occurs in about 5% of patients with solid tumor and is being diagnosed with increasing frequency as patients live longer and as neuro-imaging studies improve. In general, the most commom cancers that involved the leptomeninges are breast cancer, lung cancer, and malignant melanoma. Materials and Methods: We investigated 25 patients presented with multiple neurologic symptoms and signs who were diagnosed with leptomeningeal carcinomatosis at the Yonsei Cancer Center from January 1990 to December 1999. Results: The primary disease of leptomeningeal car- cinomatosis were stomach cancer (10 cases), breast cancer (7 cases), lung cancer (5 cases), unknown primary cancer (2 cases) and common bile duct cancer (1 case). All patients were presented with multiple neurologic symptoms and signs involving the central nervous sys- tem (CNS), cranial nerve or spinal nerves. Twenty-one of twenty - five patients were treated with intrathecal chemotherapy, radiotherapy, or combination therapy. Four- teen of them (66.7%) experienced improvement or stabilization of neurologic symptom and sign. The median survival was 122 days (10-2190). Conclusion: In conclusion, although early diagnosis and active treatment of leptomeningeal carcinomatosis may improve the quality of life in selected patients, the median survival was relatively short. Therefore, new diagnostic and therapeutic strategy for leptomeningeal carcinomatosis were needed.
