چکیده مقاله:

Histological grading is a good parameter to stratify tumors according to their biological aggressiveness. The Elston and Ellis grading method in humans, invasive ductal breast carcinomas and other invasive tumors are routinely used. The aims of this study were classification of mammary gland tumors and also application of a human grading method in canine mammary carcinoma. The samples included 37 tumors of mammary glands. Mammary tumors were carcinomas (n = 32) and sarcomas (n = 5). The carcinomas were classified as simple carcinoma 56.8% (n = 21), complex carcinoma 13.5% (n = 5), carcinoma arising from benign tumor 10.8% (n= 4) and special type of carcinoma 5.4% (n = 2). Out of 32 carcinomas studied, 37.5% (n = 12) grade I, 46.9% (n = 15) grade II and 15.6% (n = 5) grade III. This study demonstrated that the Elston and Ellis method of histological grading in canine mammary tumor is a reliable prognostic factor which is correlated with histopathological classification.

Interobserver Reproducibility of Histological Grading of Canine Simple Mammary Carcinomas.

Histological grading of canine mammary carcinomas (CMCs) has been performed using an adaptation of the human Nottingham method. The histological grade could be a prognostic factor in CMC; however, no data are available concerning interobserver variability in grading. In this study we analyzed the interobserver reproducibility between three observers when assigning individual parameter scores an...
