Microscopic DNA cytophotometry of axillary lymph node metastasis in mammary carcinomas

: 65 primary mammary carcinomas and their corresponding axillary lymphnode metastases were studied. DNA-histograms were measured in imprints using microscopical Feulgen-cytophotometry (CAS 100). Comparison between DNA histograms according to AUER-typing showed a close consent in all except five cases; with a shifting from euploidy to aneuploidy (one case), and from aneuploidy to euploidy (four cases). The clinical value of these findings should be proved.
