The relationship between basal and luminal cytokeratins with histopathologic characteristics of canine mammary gland cancer

Abstract

Neoplasia occurs mostly in mammary glands in female dogs and mammary gland cancer is one of the causes of death in these animals cytokeratins are one of the most important of tumor markers for identification of tumor prognosis. In this study, 120 canine malignant tumor samples of mammary glands were studied. From each sample, a section was taken for hematoxylin-eosin staining and two sections for immunohistochemical staining of markers CK5/6 and CK7. Histopathology slides was evaluated by light microscope. The results show that the presence of markers CK7 and CK5/6 had no significant relationship with tumor grade and type (p<0.05). However, it seems that unlike humans, CK5/6 and CK7 is not an independent prognostic factor in canine mammary gland tumors.
