Abstract

Aim: The aim of this study was to assess the size and shape characteristics of prostatic adenocarcinoma cell nuclei using a computer-assisted analysis system, and to compare the results with the Gleason score. Materials and Methods: Morphometric nuclear parameters, such as roundness factor, form ellipse, area, length, and perimeter, were evaluated based on specimen slides of 130 prostatic adenocarcinoma cases (77% needle biopsies and 23% prostatectomy specimens) using a computerized image analysis system. Correlation analysis between Gleason score and morphometric results was performed. Results: The Gleason score was correlated with mean nuclear area (r = 0.516, P = 0.01), mean nuclear length (r = 0.298, P = 0.01), and mean nuclear perimeter (r = 0.303, P = 0.01) for all specimens. In the needle biopsy group the Gleason score was correlated with mean nuclear area (r = 0.522, P = 0.01), mean nuclear length (r = 0.398, P = 0.01), and mean nuclear perimeter (r = 0.432, P = 0.01), whereas in the prostatectomy group the Gleason score was correlated only with mean nuclear area (\sigma = 0.619, P = 0.01) and mean nuclear roundness factor (\sigma = -0.425, P = 0.05). Conclusions: Nuclear size and shape factors, especially mean nuclear area, were concordant with the Gleason score. Nuclear size and shape assessment may aid in the evaluation of the pathological status of prostatic adenocarcinoma.
