Endodermal sinus tumor of the mediastinum. Report of apparent cure in two patients with extensive disease.
Overview
abstract
Primary endodermal sinus tumor (EST) of the mediastinum has been regarded as a rare and rapidly fatal germ cell neoplasm. We describe two cases of extensive EST treated with a new high-dose sequential combination chemotherapy regimen (CISCA-VB) followed by radical surgical excision. They are alive at 11 and 20 months, respectively, postoperatively. These cases stand in marked contrast to previously reported series. A new approach to the management of this tumor is proposed.
