Bilateral Versus Unilateral Lymph Node Dissection in High-Risk Prostate Cancer (BALANCE) (BALANCE)
Bilateral or Unilateral Extended Pelvic Lymph Node Dissection in High-Risk Prostate Cancer: The BALANCE Randomized Controlled Trial
BALANCE is a multicenter, prospective, randomized controlled trial enrolling men with unilateral high-risk localized prostate cancer identified by prostate biopsy, multiparametric MRI, and PSMA PET imaging. Eligible patients scheduled for robot-assisted radical prostatectomy will be randomized in a 1:1 ratio to undergo either unilateral extended pelvic lymph node dissection or bilateral extended pelvic lymph node dissection.
Pelvic lymph node dissection is commonly performed in high-risk prostate cancer for staging purposes, but its therapeutic benefit remains uncertain and the procedure may increase operative time, costs, and postoperative morbidity. Modern imaging techniques may improve the identification of patients with predominantly unilateral disease and support a more selective surgical approach.
The co-primary objectives are to compare 3-year biochemical recurrence-free survival and early postoperative PSA persistence between the two surgical strategies. Secondary objectives include comparison of perioperative complications, operative time, blood loss, length of hospital stay, quality of life, long-term oncologic outcomes, and costs.
This study is designed to determine whether unilateral extended pelvic lymph node dissection can reduce surgical morbidity while preserving oncologic outcomes in appropriately selected patients with high-risk prostate cancer.
