Flutamide‐induced regression of angiofibroma

This is the authors' abstract. We don't add key points for this paper.

Juvenile nasopharyngeal angiofibroma (JNA) appears to be an endocrine-responsive tumor. This concept was tested in five young men with JNA by treating them with a testosterone receptor blocker (flutamide) for 6 weeks preoperatively. Tumor size was evaluated by axial computed tomography both before and after flutamide therapy. Four of the five patients had an average tumor shrinkage of 44%. The patients tolerated the drug well, and the serum testosterone levels 2 or more years posttherapy were normal. This pilot study demonstrate that preoperative hormonal pharmacoreduction of JNA is a feasible adjunct to surgical therapy that offers the possibility of reduced blood loss. However, the authors believe that a formal clinical trial of this treatment approach is warranted and should be done before widespread adoption of this agent.
