A 56-year-old man with advanced esophageal carcinoma and lymph node swelling of abdomen (cStage III) underwent neoadjuvant chemotherapy (NAC) with 5-FU/CDDP. The side effect was stomatitis of grade 2. Primary tumor and lymph node swelling revealed remarkable effectiveness after 2 courses of NAC. Esophageal carcinoma was not found by endoscopy. Reduction of the lymph node was slight, however, radical resection of the esophageal carcinoma was performed. Pathologic examination of resected specimens revealed no malignant cells in the esophagus, and no metastasis of lymph node (Effect grade 3). Thus, we found NAC to be markedly effective for primary tumor and lymph nodes of esophageal carcinoma, and a radical operation was performed.
