Abstract

Background. Transrectal prostate biopsy is the standard protocol for the screening for prostate cancer. It helps to locate prostatic adenocarcinoma and plan treatment. However, the increasing number of prostate biopsies leads to considerably greater costs for the pathology laboratories. In this study, we compare the traditional method with an ink method in combination with a systematic histopathologic protocol. Methods. Two hundred consecutive transrectal prostate biopsy specimens were received from the radiology department. They were separated into two groups: one hundred were processed as six different specimens in the usual manner. The other one hundred were submitted in six containers, the apex, base, and middle section of which were stained different colours. The samples subject to the ink method were embedded in paraffin and placed in two cassettes which were sectioned using a specific protocol. Results. The comparative study of the nonink and ink methods for histopathologic diagnosis showed no statistical differences as far as diagnostic categories were concerned ( 𝑃 v a l u e < . 0 0 5 ). The number of PIN diagnoses increased when the ink method was used, but no statistical differences were found. The ink method led to a cost reduction of 48.86%. Conclusions. Our ink method combined with a specific histopathologic protocol provided the same diagnostic quality, tumor location information as the traditional method, and lower pathology expenses.
