A 51-year-old man was hospitalized for evaluation of dysphagia and bloody stool. Gastrointestinal endoscopy showed esophageal cancer invading the gastric fundus. A metastatic lesion was demonstrated in the sigmoid colon. The patient agreed to have concurrent chemoradiotherapy for the primary lesion, followed by additional chemotherapy. The first course included 30 Gy of radiotherapy given over 3 weeks, together with daily oral administration of S-1 (80 mg/m2 per day) for 2 weeks, and a 24-h infusion of cisplatin (70 mg/m2) on day 8. After a second course of chemoradiotherapy, four additional courses of chemotherapy with S-1 and cisplatin were administered, at 4-week intervals. After the additional chemotherapy, gastroscopy and colonoscopy showed disappearance of both the primary and the metastatic lesions. One year after his initial hospitalization, no recurrence of either the primary or the metastatic tumor lesions is evident.
