Case report


A 48-year-old man with unresectable gastric cancer and widespread peritoneal dissemination received concentrated ascites reinfusion therapy, followed by systemic chemotherapy. However, leptomeningeal carcinomatosis (LMC) was diagnosed 1 year later. Spinal drainage and ventriculoperitoneal shunting improved the patient’s neurological functions for approximately 2 weeks. The patient died 2 months after LMC diagnosis, but these treatments temporarily improved the quality of life during end-of-life care.
