Abstract
Der biochemischen Analyse nach der DCC-(Dextran-Coated-Charcoal)-Methode des Östrogenrezeptoren (ER)-Gehaltes von 80 primären Mammakarzinomen einschließlich 9 Metastasen werden unterschiedliche Auswertungsverfahren der immunhistochemischen ER-ICA(Estrogen-Receptor-Immunocytochemical-Assay)-Methode unter Routinebedingungen gegenübergestellt. Es zeigt sich, daß der gemessene Gehalt an Östrogenrezeptoren in engem Zusammenhang mit der angewandten Bestimmungsmethode sowie mit dem feingeweblichen Aufbau der jeweiligen Karzinome unter Berücksichtigung insbesondere auch des Tumorstromas als auch nach Möglichkeit der Tumorzellheterogenität gesehen werden sollte. The biochemical analysis of estrogen receptor (ER) content, using the DCC (dextran-coated charcoal) method, was compared with different plotting methods of the estrogen-receptor immunocytochemical assay (ER-ICA) in 80 primary breast cancers including 9 metastases under routine conditions. It was evident, that the determined content of estrogen receptors depends on the technique of measurement, as well as the microscopic organizations of the individual carcinomas and should be interpreted in respect of their content of stroma and if possible of tumour heterogeneity.This publication has 23 references indexed in Scilit:
