[Clinicopathological studies on disseminated carcinomatosis of the bone marrow occurring through metastasis of gastric carcinoma].

Five cases of gastric carcinoma (one woman) were investigated. The average age of the patients was 44 and the clinical manifestation were lumbago, melena and fatigue. Two cases were Borrmann III, and other were Borrmann IV, IIc and IIc advanced, respectively. Three were signet-ring cell carcinoma and the other two were moderately differentiated and well-differentiated adenocarcinoma, respectively. All patients showed leukoerythroblastosis. Bone marrow specimens revealed myelofibrosis in three cases, while adenocarcinoma cells were also found in three. MHA or DIC was found in three patients, all of whom died of bleeding tendency. Mean survival time was 2.6 months. Thus, bone marrow carcinomatosis proved to be very severe.
