It is well known that the larynx is a target organ for androgens and the cancer of larynx is more frequent in male subjects. We have evaluated the androgen receptors (AR) in the cytosol (ACR) and in salt extractable (ANR) and salt resistant nuclear fraction (AMR) in a group of 24 male patients with cancer of the larynx surgically removed. In addition specimens obtained from the normal mucosa of the same subjects were analyzed. In 5 patients estrogen (ER) and progesterone (PgR) receptors were also assayed. In all subjects blood samples were taken before surgery for the assay of the following hormones: LH, FSH, estradiol, testosterone, dihydrotestosterone, delta 4-androstenedione, dehydroepiandrosterone sulfate, cortisol. The results observed showed that 18 out of 24 normal larynx mucosa specimens and 17 out of 24 larynx cancer specimens were positive for ACR or ANR or AMR. The 5 samples of normal and cancer tissues analyzed for ER and PgR were negative. In conclusion there is no significant correlation between AR positivity from one size, histology, degree of differentiation and invasivity of the cancer, age of patients and hormonal blood levels from the other. The high ANR and AMR positivity (normal hormonal translocation and binding on DNA acceptors) confirm that the normal and cancer larynx are target tissue for androgens and establish the hormone dependence of this cancer. Hormonal therapy could be envisaged as an alternative or a complementary therapy for this type of cancer at least in the cases in which the analysis of hormone receptors will prove to be positive.
