[Effective treatment of AFP-producing lung cancer with UFT]

The main form of chemotherapy for non small cell lung cancer is a multiple combination therapy centered on cisplatin (CDDP). We herein report a case in which a favorable course was obtained for a patient with extremely rare AFP-producing lung cancer by single oral administrations of UFT, following extirpation of brain metastasis. The patient was an 80-year-old male whose main complaints were headache and aphasia. Following close examination, a diagnosis was made of moderately differentiated adenocarcinoma with the primary lesion in S6 of the right lung. A metastatic lesion was found in the left occipital lobe. Blood AFP was an abnormally high 17,000 ng/ml. No tumorous lesions were found in the liver. The brain metastasis were extirpated to alleviate cranial nerve symptoms, and the tissue was found to be the same as that of the primary lesion. AFP staining of the tumor tissue revealed positive cells. Because there was proliferation in the primary tumor following surgery, administration of UFT (300 mg/day Tegafur) was begun. Four weeks later the tumor had begun to shrink, and at 15 weeks was judged to be a partial response. A reduction in AFP was also seen. The patient showed absolutely no side effects from UFT, thus enabling outpatient treatment. Good results were obtained both in reducing the tumor and in maintaining the patient's quality of life.
