[A Case of Gastric Cancer Diagnosed from Ovarian Metastasis and Underwent Laparoscopic Proximal Gastrectomy after Neoadjuvant Chemotherapy].

The prognosis of patients with gastric cancer and ovarian metastasis is extremely poor, with many studies reporting survival durations within 1-2 years after diagnosis. The patient in this study was a 64-year-old female who visited a local hospital with lower abdominal pain and was referred to our hospital's gynecology department for follow-up of uterine fibroids. MRI revealed a right ovarian tumor and upper gastrointestinal endoscopy revealed gastric cancer in the upper stomach. A total hysterectomy with bilateral adnexectomy was performed, and the pathological examination revealed that gastric cancer had metastasized to the uterus and right ovary. After SOX therapy, laparoscopic proximal gastrectomy with double-flap reconstruction was performed. Postoperative pathological diagnosis was U, Ant, pType 5, 38×21 mm, por-tub, ypT4a(SE), Ly1b, V0(VB), ypPM0, ypDM0, ypN0, P0, CY0, H0, M1(OTH), ypStage Ⅳ, R0. Two years and 10 months have passed since the surgery, and there have been no signs of recurrence. In this patient, both the ovarian metastasis and primary gastric lesion were completely resected, and chemotherapy was effective, resulting in a good prognosis. Considering that gastrectomy reduces chemotherapy tolerability, the timing of gastrectomy should be considered. In addition, avoiding total gastrectomy is important for postoperative adjuvant chemotherapy.
