This case pertains to a 70-year-old man who was given a diagnosis of ulcerative lesions in the lesser curvature of the stomach on upper gastrointestinal endoscopy. Group 5 was diagnosed based on biopsy findings and the patient was referred to our department for surgery. Laparoscopic distal gastrectomy revealed the following: pT1bN2M0, pStage IIA, HER2 (IHC2+, FISH positive). The patient was followed up postoperatively; however, 8 months later, he developed hepatic metastasis in the lateral segment of the liver. Three courses of S-1+cisplatin+trastuzumab therapy were administered and shrinking of the tumor was observed. Since no new lesions were noted, laparoscopic partial hepatectomy was performed. Postoperatively, the patient was administered S-1 orally for 1 year. Currently, approximately 4 years since the hepatectomy, the patient is recurrence free. Here, we report our findings of a case in which laparoscopic partial hepatectomy was performed after chemotherapy for solitary liver metastasis noted after the surgery for HER2-positive gastric cancer.
