[Transperineal targeted prostate puncture combined with rapid pathological examination in the diagnosis of prostate cancer].

ABSTRACT

Exploring the clinical value of multiparametric magnetic resonance (Mp-MRI)-cognitive fusion method of targeted transperineal prostate puncture combined with rapid pathological diagnosis. Patients with suspected prostate cancer admitted to our hospital from 2022.01 to 2023.05 were selected as the study subjects, and Mp-MRI was performed and the suspected lesions were scored by the Prostate Imaging Reporting and Data System (PI-RADS). The enrolled patients were randomly divided into the transperineal prostate targeted puncture plus rapid pathology group (experimental group) and the transperineal prostate systematic combined targeted puncture plus conventional pathology group (control group), and the positive puncture rate, pathological findings, and complications were analyzed to compare the differences between the two groups. A total of 100 patients were enrolled, 53 in the experimental group [age 55-89 years, (73.17±7.79) years; tPSA 7.01-100 µg/L, mean 21.34 (12.38, 44.42) µg/L]and 47 in the control group [age 60-87 years, (71.96±7.07) years; tPSA 6.11-98.82 µg/L, mean 18.77 (9.04, 38.09) µg/L], and there was no significant difference between the two groups in the diagnostic positivity rate of overall PCa and clinically significant PCa (P>0.05); there was no significant difference in the highest Gleason score of pathological tissues between the two groups (P>0.05); the number of cases of medically induced sarcoid hematuria in the experimental group were significantly reduced compared with the control group (P<0.05). In terms of biopsy pain score (VAS), patients in the experimental group experienced less pain than those in the control group (P<0.05). The Mp-MRI-cognitive fusion method of transperineal targeted prostate puncture combined with rapid frozen section pathological examination can provide rapid and accurate pathological results, reduce the chance of post-puncture complications, and alleviate the pain caused by puncture sampling, which has high clinical value.
