[Effect of histologic specimen preparation on the frequency of incidental prostatic cancer].

In search of a suitable histological material handling method to record the whole number of incidental prostatic cancers, which deal with the personnel situation of a routine laboratory, the so-called 5-g-rule was evaluated in 100 cases of prostatic adenoma material. Subsequently the rest material was checked completely. A further control material were 480 irregular reviewed prostatic adenoma specimens. By the use of the 5-g-rule the frequency of prostatic cancer was increased from 6.9% to 10%. In the rest material further 9 carcinomas and much more inflammatory, atrophic and atypical-hyperplastic lesions were found. However, the 5-g-rule is for an experienced pathologist a good screening method to find the majority of carcinomas.
