Abstract

A 60-year-old woman was admitted to a medical clinic because of epigastric pain. Esophagogastroduodenoscopy revealed a submucosal tumor in the upper gastric corpus and, the tumor was subsequently resected using partial gastrectomy. The pathological findings revealed that the tumor was a gastrointestinal stromal tumor. After 4 months of observation without any adjuvant treatment, the patient was found to have liver metastasis and she was admitted to our hospital for treatment. We successfully treated the patient through sequential drug therapies, including imatinib, nilotinib, sunitinib, and regorafenib, and maintaining disease control for more than 5 years.
