Prostate cancer is the most common male malignancy.
Radiation therapy and radical prostatectomy are the main curative treatment options for organ confined disease. Despite the good long-term oncologic outcomes, roughly 40% of patients undergoing surgery develop biochemical recurrence, manifested as a rising prostate-specific antigen (PSA). Those patients are at higher risk of developing a local or distant recurrence. The diagnosis of a nodal recurrence is challenging. This report is about a 66-year-old male, who had a radical prostatectomy in 2006. Postoperatively, the PSA was never undetectable. Radiotherapy was delivered in 2007, but the PSA rose again. Anti-androgen therapy was started, but he developed painful mastodynia. A (11C) choline PET-CT showed an enlarged suspicious lymph node at the left common iliac and a salvage pelvic lymphadenectomy was performed. Postoperatively, the PSA remained undetectable for the last 5 years. The use of lesion - targeted therapy for oligometastatic disease is a new concept in urology, aiming at reducing the tumor burden. Therefore, even though this surgical approach might not be associated with a durable response over time, the tumor load is decreased and further cancer progression might be delayed, allowing to postpone the delivery of hormone therapy.
