Abstract
The author reports on the results of a rereading by 3 of 12 pathologists who gave data from 12 cities respectively, on slides of sections taken in standard fashion of lungs at autopsy using the classifications: normal, hyperplasia, metaplasia, atypical metaplasia, carcinoma-in-situ, and carcinoma. Carcinoma-in-situ and atypical metaplasia were combined leaving 5 groups for this study. The 3 pathologists read a sample consisting of 609 slides drawn from the different cities at random and 40 selected slides previously read by the 12 contributors. In 40 slides the distribution was significantly different from that previously found by the 12 readers, though not significantly different from that found by the 3 who reassessed. In the larger sample (609), differences were found to be due to the way specimens were originally read and were not real histopathologic differences.This publication has 0 references indexed in Scilit:
