We describe a case of relapsed small cell lung cancer (SCLC) recognized by a duodenal tumor, its probable metastasis. A 69-year-old man was admitted to Keio University Hospital complaining of persistent sputum production in September, 1996. A diagnosis of SCLC of the left lung invading the mediastinum was based on a transesophageal biopsy. Chemotherapy consisting of CDDP and VP-16 followed by thoracic irradiation at a total dose of 50 Gy was performed from October 1996 to August 1997, resulting in CR (Complete Response) of the tumor. In April of 1999, a mass surrounding the duodenum was found through an abdominal CT survey for tumor relapse, but no other tumors were detected in a series of CT scans or inbone scintigraphy. Subsequent fiberscopy of the upper gastrointestinal tract revealed an ulcerative tumor extensively invading the mucosa of the duodenal bulb. Biopsy specimens obtained from the duodenal tumor showed small-cell carcinoma with features similar to those of SCLC found in 1996, suggesting that SCLC of the left lung metastasized to the duodenal wall. Chemoradiotherapy with 4 cycles of CDDP and VP-16 followed by abdominal irradiation at a dose of 30 Gy was given again from May to September 1999, producing good PR (Partial Response). Although metastasis of SCLC to the duodenum seldom occurs, this report indicates that its early detection and effective treatment may prevent serious symptoms caused by obstruction of the duodenum or the papilla Vater.
