Ameeta L Nayak, Anathea S Flaman, Ranjeeta Mallick, Luke T Lavallée, Dean A Fergusson, Ilias Cagiannos, Chris Morash, Rodney H Breau,

<h4>Introduction</h4>Approximately 50% of patients with non-metastatic prostate cancer are treated with radical prostatectomy. While some men will be cured with surgery alone, a substantial proportion will experience cancer recurrence. Androgen-directed therapy (ADT) is an effective adjuvant therapy for patients treated with prostate radiation. Comparatively, the efficacy of ADT in surgical ... Read more >>
