P1-10-2 - Three Cases of Fatal Intracranial Hemorrhage with Metastasis of Gastric Cancer to the Bone/Bone Marrow

Abstract

We present three cases of intracranial hemorrhage with metastasis of gastric cancer to the bone/bone marrow. Case1: A 62-year-old man with history of distal gastrectomy 15 years ago was pointed out to have elevated ALP level and diffuse increased uptake of bone scintigraphy, which turned out to be a recurrence of diffuse metastases to bone and bone marrow confirmed by bone marrow biopsy. After partially successful treatment of chemotherapy with 6 cycles of TS-1 + CDDP, he developed an acute subdural hematoma, complicated by DIC. Craniotomy for removal of hematoma was performed. However, he was died of brain bleeding 12 months after diagnosis of recurrence. Case2: A 60-year-old man underwent subtotal gastrectomy 9 years ago. Similarly, diffuse bone and bone marrow metastasis was confirmed by bone marrow biopsy with trigger of elevated ALP level and diffuse increased uptake of bone scintigraphy. After chemotherapy with TS-1 + CDDP as 1st line and DTX as 2nd line was performed, he also developed and died of subdural hematoma with DIC 22months after diagnosis of recurrence. Case3: A 65-year-old woman with rheumatoid arthritis was pointed out to have low platelet and elevation of LDH and ALP in her regular visits. Endoscope examinations and imaging studies showed gastric cancer with multiple metastases to bone and bone marrow complicated by DIC. Although chemotherapy with TS-1 and blood transfusion was performed, she developed an acute subdural hematoma and received craniotomy for removal of hematoma. However she died of brain rebleeding 4 months after initial diagnosis.The following things are quite interesting in these 3 cases. 1) The former 2cases recurred with bone and bone marrow metastasis after long interval. 2) All cases developed bone and bone marrow metastasis complicated by fatal intracranial hemorrhage without obvious bleeding tendencies in other parts of body. We will discuss those issues with literature review.
