Abstract

A 75-year-old male patient was hospitalized for examination of abdominal trouble. Endoscopic examination simultaneously revealed 0-I pl + II c esophageal cancer and type 3 gastric cancer. Endoscopic treatment is impossible to resect the lesion completely. It is difficult for the patient to undergo an operation because he has suffered from a cardiac infarction and pulmonary trouble. Thus, gastric cancer was treated by chemotherapy and esophageal cancer by concurrent chemoradiotherapy with chemotherapy used for gastric cancer. Chemotherapy consisted of CDDP and TS-1 every 4 weeks. TS-1 (100 mg/day) was administered on days 1 to 21, and CDDP (70 mg/m2) was infused for 24 hours on day 8. Radiotherapy (5 days/week) at 2 Gy/day was concurrently started from the beginning of chemotherapy. At day 8 in the 2nd course of chemotherapy, leucocytopenia of grade 2 and appetite loss of grade 3 (NCI-CTC) were seen. Chemoradiotherapy was then suspended for one week. After recovery from toxicity, treatment was continued for a week. A total of 64 Gy was administered. After treatment, endoscopic examination with biopsy revealed the disappearance of gastric and esophageal cancer.
