Morphometry of macrophage development in malignant lymphoma. Predictive value of discriminant analysis.
Discriminant analysis of morphometric data on the ultrastructure of developing macrophages has been used to classify 62 individual subjects into one of the 3 groups of origin, namely normal, Hodgkin's disease and non-Hodgkin's lymphoma, each finding being compared with the known diagnosis. The data had been obtained from blood monocytes grown in suspension culture over a period of 6 days, and related to whole cell, nucleus, nucleoli and mitochondria. Over 80% of subjects were correctly classified as between the 3 groups and over 90% as to their normality or otherwise. Although the non-specific nature of changes in defence cells makes it unlikely that morphometric studies of macrophages will find a place in the diagnosis of specific malignancies, the present work indicates it could be useful in assessing host response and hence prognosis and response to treatment. Discriminant analysis of quantitative differences in cell structure could have wide clinico-pathological application.
