Prostate Cancer: The experience of the Radiology Service of the “Centro Médico Docente La Trinidad” in the diagnosis through Multiparametric Magnetic Resonance Imaging, Prostatic Ultrasound and its Anatomical-pathological correlation.

Abstract

Prostate cancer is an entity that represents the leading cause of cancer death in men in the world, in Venezuela in 2021 it ranked first in cancer mortality with 3,792 deaths. Through a retrospective cross-sectional analytical observational study, 79 MRI studies of patients from the Radiology Service of the CMDLT were reviewed. On average, the sensitivity of the reports according to SCORE PI-RADS v2.1, at the Centro Medico Docente la Trinidad obtained a sensitivity and negative predictive value of 91% with a specificity of 77% and an average positive predictive value of 72.6%, comparable with the international literature, however the interobserver variability index showed variability through the Kappa Fleiss with low concordance given by a value of 0.28. More studies are required in the line of research to determine the causes of interobserver variability in the use of the PI-RADS v2.1 score. One of the recommendations could correspond to the use of double reading systems in order to reduce the margin of variability.
