RESUMO
BACKGROUND: The rate of incidental prostate adenocarcinoma (PCa) detection in radical cystoprostatectomy (RCP) varies widely, ranging from 15% to 54%. Such variability may be explained by institutional differences in prostate grossing protocols. Either partial or complete submission of the prostate gland in RCP may result in detection of clinically insignificant or significant incidental PCa. The aim of the study was to compare the clinical significance of PCa in RCP specimens in partial versus complete sampling. MATERIAL: Seventy-two out of 158 RCP cases showed incidental PCa. The pathologic features, including Gleason score, margin status, extraprostatic extension (EPE), seminal vesicle invasion (SVI), PCa stage, and tumor volume, were assessed. RESULTS: The 72 cases were divided into partial (n = 21, 29.1%) and complete sampling (n = 51, 70.8%) groups. EPE was detected in 13/72 (18.1%) with 11/13 (84.6%) cases in the complete group. Positive margins were present in 11/72 (15.3%) with 9/11 (81.8%) in the complete group. SVI was detected in 4/72 (5.6%) with 3/4 (75.0%) in the complete group. Overall, 4/72 (5.6%) had a Gleason score >7, all of which were in the complete group. CONCLUSION: Our data suggest that complete sampling of the prostate may be the ideal approach to grossing RCP specimens, allowing for greater detection of clinically significant incidental PCa.

BACKGROUND: Aortic root replacement is a complex operation for severe aortic root pathology such as aneurysms and dissections with concomitant aortic valve disease. Biological and mechanical valve conduits are available. METHODS: Early and midterm results were analyzed in patients undergoing aortic root replacement. From January 1, 1998, to May 31, 2007, 144 patients underwent aortic root replacement (Bentall procedures) with either a mechanical (n = 51) or a biological (n = 93) valve conduit. Cox proportional hazard analysis was used to determine whether valve type was an independent predictor of all-cause mortality, and analysis of covariance was used to compare general and disease-specific health-related quality-of-life scores. RESULTS: Operative mortality was 2.1%. Median follow-up time was 40 months; 1- and 5-year survival rates for the mechanical group were 96.0% and 89.0%, respectively, vs 93.0% and 84.0% for the biological group. Valve type was not predictive of all-cause mortality, and valve-related complications were not significantly different between groups. At follow-up, 31.5% of patients in the biological group were on anticoagulant. General and disease-specific health-related quality-of-life scores were not significantly different between groups. CONCLUSIONS: Aortic root replacement with either mechanical or biological valved conduits is a safe procedure. Morbidity, mortality, and adverse quality of life were not associated with the type of valve conduit. Further studies are required to assess long-term durability of biological valve conduits used for aortic root replacement.
