[A case of advanced gastric cancer with peritoneal dissemination responding to S-1/CDDP neoadjuvant chemotherapy].
The patient was a 72-year-old male diagnosed with type III poorly-differentiated adenocarcinoma in the lesser curvature by gastric fiberscopy. An abdominal computed tomography (CT) scan showed the thickness of the gastric wall and the enlarged lymph node around the stomach and laparoscopic examination revealed peritoneal dissemination. The patient received neoadjuvant combined chemotherapy with S-1 and CDDP. S-1 (100 mg/day) was orally administered for 3 weeks followed by 2 drug-free weeks as a course, and CDDP (100 mg/body) was administered by intravenous drip on day 8. After the third course, significant tumor reduction was obtained. Total gastrectomy, splenectomy and D2 nodal dissection were performed. Peritoneal dissemination disappeared, and the histological diagnosis revealed complete disappearance of cancer cells in the ascites and no metastasis in all lymph nodes. The patient has now been in good health with no recurrence for 22 months after surgery. The combined neoadjuvant chemotherapy with S-1 and CDDP can be an effective treatment of choice for advanced gastric carcinoma with peritoneal dissemination.
