[A case of pulmonary pleomorphic carcinoma treated with S-1 following radiotherapy].
ABSTRACT Pleomorphic carcinoma is a rare malignancy of the lung. Here we present a 68-year-old man who was admitted to our hospital for examination of an abnormal radiogram of the chest. The radiogram revealed a large mass in the right lung field. A chest computed tomographic (CT) scan demonstrated a nonsegmentalmass like consolidation. Percutaneous CT-guided fine-needle needle biopsy from the lung was performed, and the specimen demonstrated pulmonary pleomorphic carcinoma. The patient was initially treated with two courses of cisplatin (CDDP) and docetaxel (DOC), and still showed progressive disease (PD). Therefore, we administered S-1 following radiotherapy. The chest CT revealed partial response after 4 months. We experienced a pulmonary pleomorphic carcinoma which showed a response to salvage chemotherapy with S-1.
