In 74 lung cancer patients, carcinoembryonic antigens were measured at preoperative and postoperative period using CIS RIA Kit. Thirty one cases out of 74 cases were positive, namely 41.9%. On histological types, adenocarcinoma is highly positive compared with other types, and those patients who had intrathoracic lymph node metastases were strongly CEA positive than those who had no metastasis. No positive CEA values were found in those patients who had tumors smaller than 3 cm in diameter. After the extirpation of tumors, CEA values lowered. But preoperative CEA positive patients had short survivals. Between PPD, SK/SD, Candida skin tests and CEA, significant correlation was found.
