Long-term PSA-free survival and castration-free survival with delayed antiandrogen therapy in patients with one versus two or more positive nodes at prostatectomy

Abstract

To analyze time in relation to biochemical recurrence (BCR) and antiandrogen therapy (ADT) in patients with node metastasis at retropubic prostatectomy (RRP) and to identify prognostic factors of BCR- and ADT-free survival. Positive node patients at RRP and extended pelvic lymph node dissection (ePLND) were recruited retrospectively. Neoadjuvant and adjuvant therapy were exclusion criteria. BR was defined as PSA ≥ 0.3 ng/ml or the beginning of salvage radiotherapy or, ADT. Between 1995 and 2008, 70 node-positive patients after RRP were followed without ADT. Overall, BCR-free survival was 77.9% at 2 years and 29.7% at 8 years. The median time to BCR was 59.2 months for patients with only one node compared to 27.7 months for those with ≥2 nodes. The number of positive nodes was the only independent predictor of BCR in Cox regression multivariable analysis. ADT-free survival was 78% at 2 years and 39% at 8 years. The median time to ADT for patients with only one positive node was 115 months, and the 5 years ADT-free survival was 68.8%. Gleason score and the number of positive nodes were the only independent prognostic factors of time to ADT in the Cox regression multivariable analysis. The prognosis of patients with positive nodes after RRP and ePNLD is good in terms of BCR- and ADT-free survival. After 8 years, 29.7% were still free from BCR, and 39% did not receive ADT. The number of positive nodes was the most important predictor of BCR- and ADT-free survival.
