[Magnetic resonance-ultrasound fusion guided transperineal prostate biopsy for the diagnosis of prostate cancer].

Objective: To investigate the application value of magnetic resonance-ultrasound fusion (MR-USF) guided transperineal prostate biopsy (TPPB) in the diagnosis of prostate cancer.

Methods: Relevant data were collected retrospectively from 77 patients undergoing MR-USF guided TPPB (n = 22) or 12-core systematic prostate biopsy (SPB) (n = 55) in Binhai People's Hospital from May to July 2019 and statistically analyzed using the software Graphad Prism 7.0 and SPSS 22.

PSA density in the diagnosis of prostate cancer in the Chinese population: results from the Chinese Prostate Cancer Consortium.

We performed this study to investigate the diagnostic performance of prostate-specific antigen density (PSAD) in a multicenter cohort of the Chinese Prostate Cancer Consortium. Outpatients with prostate-specific antigen (PSA) levels ≥4.0 ng ml regardless of digital rectal examination (DRE) results or PSA levels <4.
