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 prognostic 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.
PDF, 2. The focus has switched from one single marker PSA to panels of biomarkers including proteins involved in ribosomal function and heat shock proteins. Novel genetic markers such as Transmembrane protease serine 2 TMPRSS2 -ERG fusion gene mRNA or prostate cancer gene 3 PCA3 had already entered the clinical practice, raising the question whether subsequent protein changes impact the evolution of the disease and the response to treatment. A new trend in prostate cancer research is proteomic analysis of prostasomes prostate-specific exosomesfor the discovery of new biomarkers.
Predicting prostate cancer metastasis prostata la tineri tratament 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.
