Context: Treatment of Newly Diagnosed Favorable Cancer of Unknown Primary

The presence of elevated serum or tissue levels of AFP and/or beta-hCG suggests testicular cancer or extragonadal germ cell tumor in males. Men younger than 50 years with mediastinal adenopathy and pulmonary metastases have immunohistochemical evidence of AFP and/or beta-hCG in the extragonadal presentation. Diagnostic procedures and therapeutic options should proceed in these directions.
