Oestrogen receptor assay of breast cancer by immunocytochemistry of fine needle aspirates.


Sixty-five patients with operable breast cancer were studied to assess the reliability of immunocytochemical analysis of oestrogen receptor (ER-ICA) in specimens obtained by percutaneous fine needle aspiration. Results obtained with the commercially available ER-ICA kit were compared with those obtained by the routine biochemical radioligand assay of… (More)
