- Abstract
Purpose: 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. Methods: 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. Results: 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. Conclusions: 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.
