[Two patients of progressive gastric cancer accompanied by disseminated carcinomatosis of bone marrow due to bone metastasis with DIC successfully controlled by combination of S-1 and CDDP].

We performed chemotherapy with combination of S-1 and CDDP for two patients with progressive gastric cancer accompanied by disseminated carcinomatosis of bone marrow due to bone metastasis with DIC, which was successfully controlled, and they had about one-year prognosis. We think it is worth trying the chemotherapy for the patients with such a severe condition like DIC.
