Testosterone status is not associated with bladder cancer parameters in adult male patients: results of a prospective controlled study.

Abstract

Purpose: This controlled study assessed whether there was a correlation between serum total testosterone levels and bladder cancer (BCa) in terms of tumor grade and stage as objective measures in adult men.

Materials and method: Our prospectively-designed study included 257 patients who were diagnosed with primary BCa and its surgery between January 2017 and January 2020. Hundred and forty patients who had surgery in the same period with TUR for prostate or endoscopic ureteral stone treatment were included in the study as a control group. All patients in the study and control groups were male. The age range of the patients was between 34 and 90 years old. In order to examine groups, fasting blood glucose, lipid profile, albumin, total testosterone, and vitamin D levels of all patients included in the study.

Results: The relationship between tumor aggression and total testosterone level was investigated with a multinomial logistic regression model, where the control group was accepted as a reference, following adjustment for potential confounding variables, including age and serum albumin levels. Testosterone level was not found to be associated with any of the categories that determine tumor aggressiveness (p > 0.05).

Conclusion: In the present study, there was no correlation between any categories that determine tumor aggressiveness of BCa and total testosterone levels in adult men. It is obvious that our findings should be supported and further investigations are needed.
