Conclusion NLR was not an associated with survival outcomes, but rather with hydronephrosis. However, an elevated neutrophil count at baseline (>4000/mm3) was associated with worse OS and PFS. Prospective studies are necessary to validate these findings.

1 University of Nebraska Medical Center, School of Medicine, Omaha, USA; 2 University of Nebraska Medical Center, Department of Radiation Oncology, Fred & Pamela Buffett Cancer Center, Omaha, USA Purpose or Objective To assess the effect of radiation therapy on biochemical progression-free survival (bPFS) for patients with synchronous, oligometastatic prostate cancer (PC). Materials and Methods From May 2011 to May 2021, 43 patients presenting to a single center were treated for synchronous, oligometastatic PC with radiotherapy. Demographic/oncologic characteristics, treatment, and bPFS were retrospectively assessed via electronic medical record review. All patients were treated with definitive-range dosing to primary and all sites of metastatic disease will elective nodal irradation. Patients were subgrouped into those with lymph node metastases only (N1) or bone metastasis (M1). bPFS was assessed via Kaplan-Meier analysis for both groups.
