Abstract
- Thirty-two cases of surgically removed astrocytoma were evaluated for the expression of androgen receptors(ARs) immunohistochemically and the relationships between androgen receptors, DNA ploidy pattern, and survival of patients were studied. The cases included 18 grade I/II astrocytomas, 4 anaplastic astrocytomas, and 10 glioblastoma multiforme(GBM). Positive AR was present in 12 out of 32 cases(38%), which consisted of 5 cases in grade I/II(28%), 3 cases in anaplastic astrocytoma(75%), and 4 cases in GBM(40%). For both low and high grade astrocytomas, sex and ploidy pattern were not correlated with expression of the androgen receptors. Androgen receptor expression did not significantly affect the survival time. This study confirms previous reports of a low incidence of androgen receptors in astrocytomas. In addition, it shows that expression of androgen receptors is not correlated with DNA ploidy pattern and survival of patients in astrocytoma.
