摘要

The gastric cancer producing carbohydrate antigen 19-9 (CA 19-9) is a rare and unknown that characterize informations.74-year-old woman who was admitted with complaints of epigastric discomfort. An advanced cancer was found in her lower gastric region; biopsy of the tumor revealed poorly-differentiated adenocarcinoma. Her serum CA 19-9 was extremely elevated at 2322 U/ml and computed tomography demonstrated enlargement of the para-aortic lymph node; thus the tumor was considered unresectable. The patient received 8 cycles of chemotherapy with S-1/cisplatin, which shrank the para-aortic lymph node dramatically, hence she underwent D2 gastrectomy. Immunohistochemical staining of the resected cancer revealed that a third of the cancer cells were positive for CA 19-9. In addition, her serum CA 19-9 decreased rapidly after surgery and she remains alive without recurrence three years after surgery.We report one high level of CA 19-9 gastric cancer case with dramatically chemosensitive.
