A 63-year-old man was referred to our hospital because of persistent cough. Chest Xray and CT scan revealed a nodular shadow in the middle lobe of the right lung and swollen lymph nodes in the mediastinum. Laboratory findings showed marked elevated serum levels of CEA (194.6ng/mL) and CA19-9 (4448U/mL). The patient underwent right middle lobectomy and mediastinal lymph node dissection. Histopathological examination showed papillary adenocarcinoma of the lung. Immunohistochemical study of the lung specimen showed positive staining for CEA and CA19-9 on the tumor cells. This demonstrated that this tumor was a CEA- and CA19-9-producing lung cancer. The patient was treated with 60Gy radiotherapy and 2 courses of hyperthermia one month after the operation. Chemotherapy using 4 UFT capusules a day was also started 2 months after operation. The values of serum CEA and CA19-9 levels were within the normal ranges 4 months after surgery.
