[A case of esophageal cancer with excellent response to oral UFT treatment]

The patient was an 83-year-old Japanese male with the chief complaint of difficulty in swallowing. On Feb. 24, 1997, he was referred to our hospital under suspicion of esophageal cancer. X-P revealed an image of a protrusion at Im-Iu having a long diameter of 6 cm. Endoscopy revealed that the esophageal lumen was nearly completely obstructed due to the presence of an irregularly-shaped tumor. The pathological finding of biopsized specimen was a squamous cell carcinoma. Thus, this case was diagnosed as esophageal cancer, but surgery was deemed inappropriate due to the patient's advanced age. Accordingly, on March 12, treatment was started with oral administration of UFT-E granules (Tegafur, 450 mg/day). Initially, the patient was unable to ingest even liquids, but beginning around May the blockage of the esophagus disappeared. Endoscopic examination performed in June revealed that the tumor had shrunk to a about 1 cm in diameter. Although tumor tissue remained, the tumor was observed to have undergone further reduction in size at 6 months after the start of chemotherapy. Moreover, the patient gained weight. This is considered to be a very rare case of an excellent response of esophageal cancer to oral administration of only UFT agents.
