We report a case of multiple superficial esophageal cancers with liver cirrhosis successfully treated by radiotherapy. The patient was a 55-year-old man with liver cirrhosis who was under the treatment of internists at our hospital. Upper digestive tract endoscopic examination revealed multiple superficial esophageal cancers. We performed radiotherapy because pancytopenia was found in his peripheral blood data. The treatment was started on a outpatient basis, but the patient was hospitalized after sixteen treatments were finished because of hematemesis. Total irradiation was 66 Gy, and complete reduction was obtained. Eight months after the treatment, the patient shows no signs of recurrence. These results suggest that radiotherapy is an effective treatment for multiple superficial esophageal cancer.
