[A Long Term Survival Case of Gastric Cancer with Peritoneal Dissemination Responding to Intraperitoneal...

A 32-year-old woman was admitted our hospital due to epigastric discomfort. The patient diagnosed as having scirrhous carcinoma of the stomach by upper gastrointestinal scope. Peritoneal dissemination and ovarian metastasis were confirmed by the diagnostic laparoscopy. Therefore, combination chemotherapy with S-1 and intraperitoneal chemotherapy(ip)with docetaxel (DTX) was started. After 2 courses chemotherapy, laparoscopy was performed again. Peritoneal dissemination was scarred, but biopsy showed altered AE1/AE3 positive cells, and increased left ovarian metastasis, so systemic chemotherapy was changed to DCS chemotherapy and added DTX ip. After 4 courses chemotherapy and 7 months after the first diagnosis, subtotal gastrectomy, hysterectomy and bilateral adnexectomy were performed because the cytology and tumor marker remained within normal range. In histopathological diagnosis, the effect of chemotherapy was Grade 2 at the primary site and Grade 3 at the metastatic site. Nine years have passed since the initial diagnosis and she has no relapse with postoperative adjuvant chemotherapy.
