Adjuvant androgen treatment of operable breast cancer--a 20 year analysis.

One hundred and fifty-five patients with carcinoma of the breast treated by mastectomy were randomised to receive no additional treatment or to receive adjuvant testosterone. After a minimum follow up of 15 years there is no difference in either relapse free survival or overall survival between the treated and control groups. Stratification by pathological nodal status showed no benefit either for those with negative or positive axillary lymph node involvement.
