Abstract
Paraffin-embedded lymph nodes from patients with Hodgkin's disease were examined for flow cytometric DNA content. In order to increase the sensitivity of the assay we tried to enrich for the neoplastic cells by bivariate analysis using a polyclonal anti-nucleolar antibody (AN-AB) and the forward scatter (FSC). DNA aneuploidy was found to be present in 67 of all 137 cases (49%), in 24 cases only demonstrable by dual-parameter analysis. The DNA index varied from 0.69 to 1.89 with a total of 22 hypo-diploid cases. The number of aneuploid nuclei exceeded the expected frequency of Reed-Sternberg (RS) and Hodgkin (H) cells in most of the analysed specimens. In conclusion, flow cytometry in Hodgkin's disease appears to give useful informatipn regarding the ploidy status and evidence has been provided that the malignant cell population in Hodgkin's disease is not limited to the classical RS/H cells.
