Comprendre le cancer de la prostate
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 journal publishes original articles revealing recent research results in public health and management, review articles providingup-to-date analysis or discussion on research previously published by others, case reports describing interesting and exceptional clinical cases the authors have confronted with. Recognition of this malignant neoplasia is important because of its particularities: diagnosis in advanced stages, normal or low serum prostate specific antigen PSA and poor prognosis. It also shows no response to hormonal therapy, such as acinar adenocarcinomas and requires early aggressive treatment. We present the case of a male patient who suffered a transurethral prostatic resection surgery. Histopathological examination revealed a malignant neoplastic proliferation with predominantly papillary architecture composed of conjunctive-vascular cores lined by tall cylindrical epithelium with atypical pleomorphic nuclei and mitoses.
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, cancer de la prostate diagnostic, 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.
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.
