To demonstrate that the level of prostate-specific antigen is useful as a predictor of bone metastasis in patients with prostate cancer. Materials and methods: Retrospective, observational study of diagnostic test type performed in the Urology Department of the Víctor Lazarte Echegarays Hospital, which included a total of 178 patients diagnosed with prostate cancer. Sensitivity, specificity, PPV, NPV and area under the curve were calculated according to different PSA levels. Results: PSA, using 20ng/mL as cut-off point, presented a sensitivity of 78.26%, a specificity of 69.03%, a positive predictive value of 27.27% and a negative predictive value of 95.54%. The area under the curve calculated with a PSA level of 20.25 ng/mL, corresponding to a Youden index of 0.472, was 0.77, which corresponds to a prognostic accuracy of 77% (p<0.05). Conclusions: PSA levels can be used as a predictor of bone metastasis in patients diagnosed with prostate cancer.
