INTRODUCTION. Prostate-specific antigen (PSA) is a glycoprotein that is expressed by both normal and neoplastic prostate tissue. PSA is consistently expressed in nearly all prostate cancers, although its level of expression on a per cell basis, especially in very poorly differentiated prostate cancers, is lower than in normal prostate epithelium.

A key issue is the typical course of prostate cancer. Prostate cancer usually progresses slowly over many years. Therefore, it's possible to have prostate cancer that never causes symptoms or becomes a medical problem during your lifetime. Limitations of the test.

Men with prostate cancer that has spread to the bones may consider treatment that infuses a radioactive substance into a vein. Strontium-89 (Metastron), samarium-153 (Quadramet) and radium-223 (Xofigo) are medications that target fast-growing cancer cells in the bones, and may help relieve bone pain.

Accurate localization of prostate cancers could also potentially assist in decision-making regarding the use of active treatment or active surveillance in selected patients. Herein, we will review multiparametric MRI (MP-MRI) for localized prostate cancer, emphasizing its potential role in risk stratification and improving outcomes.
