ABSTRACT
OBJECTIVE:
MRI of the prostate improves diagnostic accuracy of prostate cancer. Different fusion approaches with transrectal ultrasound images are employed. To determine detection rate of prostate cancer in men undergoing transperineal MRIbased cognitive fusion biopsy. MATERIALS ANDMETHODS:
One hundred and sixty-four consecutive men underwent a multiple-core prostate transperineal biopsy. Univariable and multivariable logistic regression analyses were used to address the relationship between clinical parameters and prostate cancer detection rate.RESULTS:
One hundred and fourteen patients underwent mpMRI prior to the transperineal biopsy, 52 (45%) were diagnosed with prostate cancer, of them, 36 had Gleason score ≥7 (69%). Among these 114 patients, 82 had suspicious lesions on MRI, and 43 of them were diagnosed with cancer (52%). On multivariate analysis, the most significant independent predictive factors were PSA density (P<0.001) and suspicious MRI lesion (P=0.006). Men with a PSA density of more than 0.22 and a suspicious lesion on MRI had a detection rate of 78%. Detection rate among 50 patients with no MRI study prior to this biopsy was 26%.CONCLUSIONS:
This study showed that among a group of mostly multi-biopsied patients, the presence of mpMRI lesions and high PSA density values helped to detect clinically significant prostate cancer using cognitive MRI/TRUS fusion biopsies.Palavras-chave
