[A Case of Long-Term Recurrence-Free Survival after Local Resection of Pancreatic Metastasis of Gastric Cancer].

A 72-year-old man who had received total gastrectomy for gastric cancer(MU, circ, Type 3, pT4b[SI: transverse colon], N3b, M1[CY1], pStage Ⅳ). He underwent postoperative adjuvant chemotherapy(S-1)for 6 months after surgery. Four years and 4 months after surgery, a 3 cm-sized mass was found at the pancreatic tail, and the mass was suspected of pancreatic metastasis from gastric cancer or primary pancreatic cancer. Distal pancreatectomy was performed. The operation time was 4 hours and 56 minutes, the blood loss 250 g. A minor leak in the transverse colon was observed after the surgery, and he was treated conservative measures. He was discharged from the hospital 24 days after the surgery. Pathological examination found that the mass was pancreatic metastasis of gastric cancer. After the operation, he was treated with DS therapy(S-1+docetaxel)for 1 year and has been alive without recurrence for 4 years and 2 months after resection of the recurrent tumor. Gastric cancer pancreatic metastasis is rare, but if the tumor is solitary, resection can be expected to result in long-term recurrence-free survival.
