[A case of advanced gastric cancer with esophageal invasion treated by neoadjuvant S-1/CDDP chemotherapy].


PMID 23863737

Abstract

A 75-year-old man was found, by endoscopic examination, to have type 2 advanced gastric adenocarcinoma with esophageal invasion in the cardia. Endoscopy and other modalities revealed observable esophageal invasion. To minimize surgical intervention, we treated him with S-1 and cisplatin as neoadjuvant therapy. Treatment was as follows: S-1(80mg/m2)was administered orally for 3 weeks followed by 2 weeks of rest, and cisplatin(60mg/m2)was administered by intravenous drip on day 8. Two courses of treatment resulted in marked shrinkage of the primary lesion and improvement of the esophageal invasion. Total gastrectomy with splenectomy, and D2 lymph node dissection were performed with an adequately long proximal margin, without thoracotomy. Pathological efficacy was Grade 2. At present, 1 year after the operation, the patient presents no evidence of a recurrence. We concluded that through neoadjuvant chemotherapy for advanced gastric cancer with esophageal invasion, thoracotomy could be avoided, thereby reducing risks associated with surgery.
