Suitability of tissue prints for immunocytochemical diagnosis of mammary cancer.
The present study was aimed at evaluating suitability of tissue prints for immunocytochemical evaluation of mammary cancer cells. The prints, originating from 30 cases of mammary cancer were studied using immunocytochemical reactions with monoclonal antibodies against estrogen and progesterone receptors, metallothionein (MT), P-glycoprotein and cytokeratins (clone LP34). Expression of individual antigens was assessed using the scale in which intensity of the colour reaction and percentage of positive cells were taken into account. The obtained results did not differ qualitatively or quantitatively from those obtained in paraffin sections. The studies have shown that tissue prints can be used for reliable immunocytochemical evaluation of expression of various proteins in mammary cancer cells.
