Dramatic response of teratoma-associated non--germ-cell cancer with all-trans retinoic acid in a patient with nonseminomatous germ cell tumor

Published on Friday, 20 January 2017


A patient with nonseminomatous germ cell cancer, treated with standard chemotherapy, subsequently developed a pathologically confirmed metastatic undifferentiated adenocarcinoma (non-germ-cell elements) arising from residual teratoma.

Disease was present in both lobes of the liver and was deemed unresectable at the time of presentation

The patient was treated on a National Cancer Institute-sponsored institutional protocol with all-trans retinoic acid.

After 60 days of oral therapy at a dose of 150 mg/m2/d (50 mg/m2 three times daily), the patient was found to have complete radiologic resolution of his hepatic metastases.

He subsequently underwent surgery and his complete response was pathologically confirmed.
