[Successful withdrawal from disseminated intravascular coagulation caused by disseminated carcinomatosis of bone marrow originated from gastric cancer treated by sequential therapy consisting of MTX and 5-FU and palliative radiotherapy].

A 5 8-year-old man with severe back pain caused by multiple vertebral metastases developed disseminated intravascular coagulation(DIC). We adopted palliative radiotherapy(8 Gy/1 day)for palliation of his back pain as initial treatment. Afterwards, we started sequential chemotherapy consisting of methotrexate(MTX)and 5-fluorouracil(5-FU). After two courses, DIC was resolved, and the patient was discharged in fair condition after five more courses of MTX and 5-FU therapy.
