Background: In these financially challenging times, it behoves us as pathologists to influence our own fiscal decisions. We need to critically analyze our time honored published methods of gross prostate pathology. For processing radical prostatectomy specimens, we decided to utilize the least number of histologic blocks which yielded the most information for TNM staging and histologic grading.
Design: We adopted a novel capsular dissection akin to the widely accepted method of processing encapsulated follicular neoplasms of the thyroid. We have processed two hundred and seventy-nine radical prostatectomies by the capsular method and prospectively analyzed grade and stage on ten specimens by comparing capsular processing to whole gland processing.
Results: The TNM staging was the same with both methods except for T2b which could not be assessed by the capsular method. The grading remained unchanged in both methods. The mean number of blocks by the capsular method was twenty compared to forty-two blocks by whole gland processing.
Conclusions: We conclude that the capsular method is cost-effective and less labour-intensive than other methods without significantly compromising either stage or grade.
