Salvage Moderate Hypofractionated Versus Ultrahypofractionated Radiotherapy for Biochemical Recurrence After Radical Prostatectomy in Prostate Cancer: A Prospective, Multi-Center, Randomized Phase III Non- Inferiority Trial (HUB Trial)
This study is the first prospective, randomized phase III clinical trial designed to evaluate whether ultrahypofractionated radiotherapy is non-inferior to conventionally moderately hypofractionated radiotherapy in terms of efficacy, with acceptable toxicity, in patients who develop biochemical recurrence following radical prostatectomy. Considering the potential clinical benefits of shorter treatment duration, cost reduction, and improved patient convenience, this study is expected to provide important evidence to optimize salvage radiotherapy strategies in routine clinical practice.
• Patients who have undergone radical prostatectomy for prostate cancer
• Age ≥ 20 years
• Persistent prostate-specific antigen (PSA) elevation after radical prostatectomy, defined as prostate-specific antigen (PSA) levels of 0.1-1.0 ng/mL with at least three consecutive increases
• Patients who have undergone prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) for evaluation of prostate-specific antigen (PSA) elevation
• Good performance status (ECOG performance status 0-1)
