Successful preoperative chemotherapy with S-1 plus low-dose cisplatin for advanced gastric cancer with synchronous liver metastases: report of 2 cases

Chemotherapy. 2007;53(5):378-82. doi: 10.1159/000107726. Epub 2007 Sep 3.


We report 2 cases of advanced gastric cancer with synchronous liver metastases who were successfully downstaged using S-1 plus low-dose cisplatin chemotherapy followed by surgical resection. S-1 was administered orally (80 mg/m(2)/day) twice daily for 14 consecutive days, and cisplatin (15 mg/m(2)) was infused over 1 h on days 1 and 8. Successful downstaging of the hepatic metastases was confirmed by imaging analyses; however, neither patient showed a complete response of the primary lesion in the stomach. Toxicities, according to the WHO criteria, were mild. The patients underwent surgical resection within 4 weeks after the last chemotherapy. Postoperatively, they were discharged without complications and received adjuvant chemotherapy. Both patients remained alive and well at 17 and 12 months after surgery, respectively, without recurrence. These cases provide further evidence that S-1 plus low-dose cisplatin chemotherapy enables downstaging of advanced gastric cancer and a subsequent potentially curative resection without serious complications.
