Objective: In this study, we investigated the importance of gleason score in detecting bone metastasis in prostate adenocarcinoma patients whose prostate-specific antigen PSA level ≤ 20 ng / ml Materials and Methods: Prostate adenocarcinoma cases diagosed by 10-quadrant transrectal ultrasound-guided prostate biopsy were divided into 2 groups of total gleason score ≤6 30 patients and total gleason score >6 50 patients . Both groups compared in terms of age, total PSA and metastasis on bone scintigraphy.Results: The mean age was 69.60 ± 6.56 in patients with gleason score ≤6 and 70.68 ± 8.34 in patients with gleason score > 6 p=0.153 . The mean PSA level was 12.10 ± 4.57 mg/ dl in patients with gleason score ≤ 6 and 13.11 ± 4.53 in patients with gleason score >6 p=0.652 . There was no singnificant difference in terms of age and total PSA however metastasis on bone scintigraphy was significantly higher in the patient with gleason score>6 p6 and PSA level ≤ 20 ng/ml. We suggest bone scintigraphy in prostate cancer patients with gleason score > 6 for metastatic evaluation even if PSA level is less than or equal to 20 ng/ml
