title: Silver-stained nucleolar (Ag-NOR) cluster size in feline mammary carcinomas: lack of correlation with histological appearance, mitotic activity, tumour stage, and degree of nuclear atypia.
abstract: The relationship between Ag-NOR cluster size, mitotic index, tumour stage, degree of nuclear atypia and histological appearance was evaluated in a series of feline mammary carcinomas. The mean Ag-NOR cluster area per cell in these tumours ranged from 1.86 to 6.25 microns 2 and was not related to any other parameter studied. This suggests that Ag-NOR cluster size measurement is of poor diagnostic and prognostic value for feline mammary carcinomas.
