Development of an automatic program for the stereological estimation of the volume weighted mean volume of cell...

A stereological method was recently developed for the estimation of the volume weighted mean volume of particles from 2D sections. Several authors successfully applied this manual method to paraffin sections of bladder cancers and malignant melanomas and found a good correlation between the mean nuclear volume and the histological grading and prognosis of these tumors. The implementation of this measuring method on an automatic image analyser, devoted to routine work in tumor pathology, is presented. The accuracy of the automatic measurement has been evaluated together with the first results obtained from human esophageal cancers.
