Abstract
The near exclusivity of juvenile angiofibroma to adolescent and young adult males points to an obvious hormonal influence. Immunohistochemical evaluations on tumor specimens have demonstrated receptors to testosterone and other sex hormones. Treatment with the anti-testosterone agent flutamide is currently the most accepted and efficacious modality to bring about presurgical tumor reduction. Six-week treatment with oral flutamide has been documented to be effective in bringing about tumor volume shrinkage in the postpubertal population (mean 16 %, maximum 40 %), but is expectedly ineffective in the prepubertal population who have negligible circulating testosterone levels. Presurgical tumor volume reduction has the potential to enable tumor excision by a less invasive approach, to facilitate tumor dissection from vital nerves and vessels, and to limit surgical complications and blood loss.
