Abstract
We report a case of gastric cancer that metastasized from ovarian cancer. A-69-year-old woman had undergone total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, and pelvic lymphadenectomy for ovarian cancer following neoadjuvant chemotherapy. Two years and 5 months after the operation, she was admitted to our hospital with abdominal pain. Gastroscopy revealed a type 2 tumor and a biopsy was performed. Histology showed that the tumor was a serous adenocarcinoma similar to the primary ovarian cancer, which led to a diagnosis of metastatic gastric cancer originating from the ovarian cancer. Computed tomography (CT) scan showed that the tumor had directly invaded the pancreatic body ; thickening of the lower third of the stomach wall and swelling of the abdominal para-aortic lymph nodes (PAN) were also identified. According to the ovarian cancer treatment guidelines (2015), we planned a secondary debulking surgery. After chemotherapy, the pancreatic invasion disappeared. Distal gastrectomy, D2 lymphadenectomy and PAN lymphadenectomy were performed. The postoperative course was uneventful and the patient has remained free of disease since the operation.
