Primary anterior mediastinal seminoma

Abstract

A review of the Mayo Clinic experience with primary anterior mediastinal seminomas involved 17 patients who had pure anterior mediastinal seminomas and four who had mixed germ‐cell tumors containing seminoma. At follow‐up, of the 17 patients with pure anterior mediastinal seminoma, nine had no evidence of disease and eight had died of metastatic disease. Of the four patients with mixed germ‐cell tumor containing seminoma, two were alive at follow‐up and two had died of metastatic disease. In the group with pure anterior mediastinal seminoma, these factors seemed to have been associated with a greater potential for progression of disease: older than 35 years of age, presentation with fever, superior vena caval syndrome, supraclavicular or cervical adenopathy, and roentgenographic evidence of hilar disease.
