Anatomo-radiological correlation of prostate cancer: Experience within the University Hospital of Fez (about 36 cases)

Abstract

Prostate cancer is a real public health problem. It is the second most common cancer in men, due to longer life expectancy, especially in developed countries. The diagnosis is confirmed by histology after the prostate biopsy, the latter also makes it possible to assess the severity by the Gleason score. Multiparametric Magnetic Resonance Imaging (MRI) currently plays an important role in the detection and localization of intra- and extra-prostatic tumor foci by combining the 3 sequences (T2 sequence, diffusion sequence, perfusion sequence). This examination thus makes it possible to evaluate the severity of the tumoral lesion through the PIRADS score. In our series, the PIRADS score varied between 3, 4 and 5. We have illustrated through a review of the literature that multiparametric MRI data are correlated with prostate biopsy data. The presence of a clearly identifiable lesion on mpMRI is correlated with an increase in the Gleason score on the prostate biopsy. In our study, it was shown that there is a statistically significant positive correlation between the PIRADS score and the Gleason score. The use of multiparametric MRI of the prostate is therefore a good means of screening, diagnosis and locoregional extension of prostate tumors. However, its use remains limited by its availability and high cost.
