[Pancytopenia and ARDS with high dose hepatic arterial infusion]

The patient was a 74-year-old woman with gastric cancer with multiple liver metastasis. She was treated with daily oral administration of TS-1 100 mg/day (day 1-21) and systemic administration of CDDP 90 mg (day 8) as neoadjuvant chemotherapy for 2 courses. As metastatic lesions became smaller, we performed distal gastrectomy. TS-1 was started for the residual cancer lesion. However, liver metastatic lesions increased in size, so we carried out intraarterial chemotherapy (IAC), Nausea appeared at 9 days, pancytopenia at 28 days and ARDS at 78 days after IAC. She died due to ARDS.
