- A series of transitional cell carcinomas of bladder were stained immunohistochemically with the monoclonal antibody, 32-2B, to desmosomal glycoprotein 1. All of the sections showed positive staining with the antibody. Assessment of staining intensity, by 3 independent examiners, revealed a strong negative correlation between density of desmosomal staining and degree of invasion ( P=0.012). Nests of strongly staining cells were identified in several invasive tumours, possibly indicating early squamous differentiation. Invasive tumour cells in the subepithelial stroma also stained strongly with the antibody. Correlation with clinical course, however, revealed no significant association between desmosomal staining and the incidence of recurrence or progression. It is suggested that staining with this antibody may be of value in detecting both stromal invasion and early squamous differentiation of transitional cell carcinomas. Both this and previous studies emphasise the value of this antibody as an epithelial marker in neoplasia. [ABSTRACT FROM AUTHOR] |
