Objective: The objective of the study was to assess the association between the level of total serum testosterone in prostate
cancer patients before radical prostatectomy and pathological Gleason score and pathological stage.
Material and Methods: We measured preoperative levels of total circulating testosterone by the chemiluminescence
method in peripheral blood samples in 201 Slovak prostate cancer patients. In all patients, their age was listed, and we
also assessed other preoperative and postoperative (pathological Gleason score and pathological stage) data/prognostic
factors by multiple types of examinations. We used multinomial logistic regression to evaluate the potential use of
total testosterone as a possible predictor of the pathological Gleason score and pathological stage.
Results: We have found a highly significant association between age and total preoperative testosterone (p-value = 0)
in men with prostate cancer. The results also pointed to the fact that total serum testosterone (as a single predictor, or
in combination with other preoperative prognostic factors – PSA in peripheral blood, clinical stage and biopsy Gleason
score) is not a statistically significant predictor of the pathological Gleason score and pathological stage.
Conclusion: Despite the fact that testosterone plays a crucial role in carcinogenesis of the prostate, total serum testosterone
was not a statistically significant predictor of pathological Gleason score and pathological stage in the population
of Slovak men.
