There is a discrepancy in the Gleason score given on the initial biopsy and prostatectomy specimen, respectively, that affects both patients who can benefit from active surveillance and those who cannot benefit from curative surgical treatment, and for whom therapeutic alternatives must be established.

In this context, our study aimed at analyzing the diagnostic concordance between biopsies and subsequent prostatectomies, in order to establish the accuracy of prostate biopsy in predicting final Gleason score of the prostatectomy specimens.

Material and methods: We analyzed 79 cases of PADK, initially diagnosed by prostate biopsy and subsequently treated by radical prostatectomy.

The accuracy degree of the tumoral grading system assigned to the prostate biopsy, compared with the radical prostatectomy, was assessed by calculation of the Cohen's kappa concordance coefficient and calculation of sensitivity, specificity, positive prostate cancer staging mri value and negative prognostic value.

Results: 37 cases In prostate biopsies, 32 cases The lowest agreement rate was observed for Gleason score 5, where no case showed a similar score for biopsy and prostatectomy. Statistical analysis indicated a kappa coefficient of 0. The agreement on ISUP prognostic grade groups between prostate biopsy and radical prostatectomy indicated a slight increase in kappa coefficient Conclusions: Our results demonstrate an increase in the predictive accuracy of prostate biopsy, as a result of the application of prognostic grade group system, which ensure the decrease of overestimating tendency of the old scoring system, ultimately leading to a preliminary characterization of potential lesions in prostatectomy specimens and a more effective treatment stratification of patients.

Endorectal coils ERC are useful, but now rectal cancer on mri can get a prostate MRI without any discomfort, and the quality and accuracy is on par with the standard, invasive diagnostic methods. Endorectal coils — a thing of the past? Most facilities use an ERCwhich is a special coil that is inserted into the rectum through the anus, and is usually covered by a lubricated balloon or condom. Apart from the obvious sensitive nature of the insertion process, the coil has to stay in until the procedure is over.
