Salvage Pelvic Lymph Node Dissection After Fluciclovine Positron Emission Tomography/Computed Tomography Detected...

Multiple new systemic agents have been targeted to metastatic prostate cancer, with decreased progression of disease but no cure. Surgical management of metastatic disease has been gaining interest, primarily in the setting of high-risk prostatectomies. However, metastasis-directed surgical intervention has been employed in rare scenarios, especially in oligometastatic disease. We report here on a salvage robot-assisted pelvic lymph node dissection for a solitary metastatic site. A 63-year-old Hispanic man who was initially treated with prostatectomy for intermediate risk cancer developed rapid biochemical recurrence. After salvage radiation, fluciclovine positron emission tomography (PET)/computed tomography (CT) scan showed a solitary pelvic lymph node metastasis. A robot-assisted laparoscopic pelvic lymph node dissection was carried out, with subsequent nadir of his prostate-specific antigen at 0.026. To our knowledge, this is the first report of salvage pelvic lymph node dissection after metastatic detection by fluciclovine PET/CT scan. Our patient experienced a complete biochemical response; however, it remains to be seen whether this will be a lasting response. Surgical resection of metastatic sites in prostate cancer offers a safe alternative to systemic therapy and avoids systemic side effects.
