Endodermal sinus tumor: a report of two sustained remissions treated postoperatively with a combination of actinomycin D, 5-fluorouracil, and cyclophosphamide.

The literature reflects a poor prognosis for women with endodermal sinus tumor. Two women with this neoplasm, 1 having stage IA and the other stage IIB disease were treated for 1 year postoperatively with a combination of actinomycin-D, 5-fluorouracil, and cyclophosphamide. Each had therapy discontinued after a negative second laparotomy and 15 and 21 months later are without recurrence. It is suggested that this drug regimen is a benficial adjunct to surgery in the treatment of endodermal sinus tumor.
