Lack of efficacy of imatinib in a patient with metastatic Leydig cell tumor

Cancer Chemother Pharmacol. 2006 Nov;58(5):716-8. doi: 10.1007/s00280-005-0181-6. Epub 2006 Feb 1.

Abstract

Imatinib is a tyrosine kinase inhibitor with activity in gastrointestinal stromal tumor and a variety of other solid and hematological malignancies. Studies in vitro and in a mouse model suggested that the imatinib might also be active in malignant Leydig cell tumor. We report on the--to our knowledge--first treatment experiment with imatinib in a patient with metastatic Leydig cell tumor. Unfortunately, the tumor progressed during treatment.
