We report a 47-year-old female patient who was suffering from severe DIC due to multiple bone metastases. This patient was treated weekly with an intraarterial 5-FU (500 mg) and MTX (100 mg) including AT-II by a subcutaneously implanted port system placed into her abdominal aorta. Furthermore, she was administered tegafur/uracil (400 mg/day) 5 days weekly for pharmacokinetic modulating chemotherapy (PMC). After three courses of PMC treatment, DIC was resolved and the tumor marker was reduced. However, after 22 courses of this regimen, DIC suddenly recurred. As second line chemotherapy, we then administered paclitaxel (80 mg) in place of CDDP. After five courses of this second line chemotherapy, DIC recovered and the tumor marker was again decreased. We concluded that this chemotherapy is effective for advanced gastric cancer complicated with bone metastasis and DIC from the standpoint of toxicities, antitumor effect and QOL of the patient.
