[Adjuvant chemotherapy of S-1 and CDDP for undifferentiated adenocarcinoma of the stomach].
A 67-year-old female visited our department complaining a general fatigue. Gastrointestinal endoscopy revealed a giant ulcer at distal portion of the stomach. NSE was the only tumor marker showing an abnormal value. Pathohistology of the biopsy specimen showed a monotonus massive growth of small irregular tumor cells. Distal gastrectomy with regional lymph node dissection was carried out. Final pathology report was undifferentiated adenocarcinoma of the stomach, exposing itself to serosa with lymph node metastasis. Postoperative chemotherapy was started using S-1. However, despite NSE turning normal, CEA rose that CDDP was added to the regimen. She went into remission for several months but CEA rose again and CDDP was changed to CPT-11. To our great regret, she died six months after the operation. Undifferentiated adenocarcinoma of the stomach is rare disease. Immunohistochemical staining is useful for a differential diagnosis. Prognosis is said to be poor but S-1/CDDP may contribute to prolong prognosis.
