Do Testosterone Levels Affect PSA Values When Monitoring Prostate Cancer Patients Treated by Radiation Therapy and Hormone Therapy?

Neoadjuvant hormone therapy (NHT) when given to men receiving radiation therapy (RT) for prostate cancer is known to affect long term testosterone (T) levels. Men with suppressed T may experience a lower PSA value which could influence biochemical failure determinations. We sought to determine which factors influenced the last measured T and PSA values and the relationship between the two.
