Total androgen blockade and LH-RH agonists are more effective in lowering testosterone values (to castration values) compared to the antiandrogen monotherapy, where testosterone values stay above the castration level. This therapy approach has advantages, since it decreases testosterone values providing better therapy response. There is a difference in testosterone values, but not significant, when total androgen blockade and monotherapy with LH-RH agonists are administered. Registered lower basal values of LH in all patients with prostatic cancer open the possibility to introduce LH as a new additional, significant marker in diagnosis of this neoplasm.
