[A case of locally advanced residual gastric cancer treated with combined resection of multiple adjacent organs].

A 60-year-old man was diagnosed as having type 3 advanced gastric cancer in the gastric antrum and multiple liver metastases( S2, S3, S4, and S7)( cT3[ SS] N0M0H1, Stage IV). The patient received combined neoadjuvant chemotherapy with S-1 and cisplatin( CDDP). S-1( 80 mg/body/day) was administered orally for 3 weeks followed by 2 drug-free weeks as a course, and CDDP (60 mg/m2) was administered by intravenous infusion on day 8. The gastric tumor reduced in size and the liver metastases improved after 5 courses of treatment. Distal gastrectomy, D2 lymph node dissection, and partial liver resection( 4 sites) were performed. S-1 alone was continued as adjuvant chemotherapy; no recurrence was detected in 2 years and 2 months after surgery. Although there is insufficient evidence to support the benefit of surgical resection in patients with advanced gastric cancer with liver metastases, chemotherapy combined with surgical resection would improve the survival time without deterioration of quality of life of these patients. This case suggests that neoadjuvant chemotherapy is effective against advanced gastric cancer even with multiple liver metastases.
