[An intractable gastric cancer showing an extremely effective response to immunochemotherapy]

Reported herein is the case of a terminal patient with advanced gastric cancer who was shown an extremely effective response to immunochemotherapy. The patient, a 62-year-old female, was determined as having a gastric cancer, Borr. type 2, originating in the pyloric antrum. The tumor was found to be H3P3S2N2 (stage IV), and its histology revealed a mucus-producing papillary adeno-carcinoma, ss gamma, n(+), ly2, and V1. Thus the patient underwent a distal gastrectomy, and was given an operative administration of MMC, followed by postoperative immunochemotherapy with FT 207 and OK 432. Consequently, no ascites were noticed throughout the recuperative course, and repeated CT scannings of the hepatic metastatic lesions, revealed a remarkable regression. Two years after this operation, she resumed normal daily life. Further, her preoperatively elevated tumor markers have returned to normal.
