An Expert Discussion of Testosterone Nadir and Clinical Outcomes in Patients with Advanced Prostate Cancer: A Post Hoc Analysis of Triptorelin Pamoate Phase III Studies
Dr. Klotz also addresses the overall survival (OS) and disease-specific survival (DSS) by testosterone suppression group, assessed by Kaplan–Meier analysis with a log-rank test. He concludes the review by describing how, in the sample size comprised of 592 patients, low nadir testosterone achieved during treatment with the LHRH agonist triptorelin was associated with improved OS and DSS in patients with advanced prostate cancer.
Dr. Klotz and Dr. Shore then discuss the impact of the results from this trial and the potential future direction of treatment options for men with prostate cancer.
