The presence of estrogen receptors in laryngeal carcinoma is controver
sial; with two independent methods (testing the binding of monoclonal
antibodies against receptor protein by immunohistochemistry binding of
labelled H-3-estradiol with the charcoal-dextran method), the levels
of ER were found to be, if any, extremely low and without correlation
to age, sex and previous radiation therapy of the patient. Administrat
ion of antiestrogens (if rationalized by the presence of ER) is theref
ore not indicated.
