Probability of XXXX according to the percentage of positive biopsy cores in clinically @entity263 .

@entity1 @entity263 @entity66 @entity5 @entity3
OBJECTIVE: Prediction of @entity66 in clinically @entity263 is relevant for treatment planning of the disease. The purpose of this study was to explore the usefulness of the percentage of positive biopsy cores to predict the chance of @entity5 . MATERIALS AND METHODS: We evaluated 1787 @entity1 with @entity263 submitted to radical prostatectomy. The percentage of positive cores in prostate biopsy was correlated with the pathologic outcome of the surgical specimen. In the final analysis, a correlation was made between categorical ranges of positive cores (10% intervals) and the risk of extraprostatic extension and/or bladder neck invasion, seminal vesicles involvement or @entity3 to iliac lymph nodes. Student's t test was used for statistical analysis. RESULTS: For each 10% of positive cores we observed a progressive higher prevalence of @entity66 . The risk of @entity5 beyond the prostate capsule for <10% positive biopsy cores was 7.4% and it increased to 76.2% at the category 90-100% positive cores. In @entity1 with Gleason grade 4 or 5, the risk of @entity5 prostate was higher than in those without any component 4 or 5. CONCLUSION: The percentage of positive cores in prostate biopsy can predict the risk of @entity5 outside the prostate. Our study shows that the percentage of positive prostate biopsy fragments helps predict the chance of @entity5 and may have a relevant role in the @entity1 's management.
