Gastric carcinoma I. The reproducibility of a histogenetic classification proposed by Masson, Rember and Mulligan.

ABSTRACT

The purpose of the present paper has been to examine the reproducibility of the classification of gastric carcinomas, as proposed by Mulligan and Rember. Two microscopic slides from each of one hundred randomly selected specimens of gastric carcinoma, obtained by gastrectomy or gastric resection, were classified independently by both authors. Neither of the authors knew which slides originated from the same specimen. The inter-examiner reproducibility rate was 79 per cent. The reproducibility rates of the diagnoses with two independent slides from the same tumour was 74 per cent with examiner I and 80 per cent with examiner II.
