Histopathological and immunohistochemical analysis of predictive and prognostic markers in spontaneous canine mammary cancer
The study investigates the interspecies similarities between canine and human mammary cancer in the sense of innovative predictive and prognostic tumour markers. Surgical resection specimens with diagnosed spontaneous primary mammary cancer obtained from 100 female canine patients were included in this study. Expression of carbonic anhydrase IX (CAIX) enzyme and human epidermal growth factor receptor 2 (HER2) expression was evaluated immunohistochemically. The study was completed with investigation of Ki67 expression and proliferation with marker of myogenous differentiation. Histopathological grading was performed using the Nottingham/modified Bloom-Richardson system. As in humans, our analysis of canine mammary cancer has shown that CAIX positivity in tumour cells significantly correlates with higher levels of HER2 immunoreactivity (P = 0.001), and increased tumour grade (P < 0.001). The percentage of smooth muscle actin (SMA) positive cases was significantly higher (P = 0.002) in the group of mammary carcinomas with CAIX positivity compared to the tumours that were negative. Using antibody Ki67 proliferative activity was not significantly different between mammary tumours that were CAIX positive and CAIX negative. Canine mammary gland carcinomas may, therefore, represent valuable animal models for the study of hypoxic signaling pathways involved in mammary carcinogenesis in humans. Further research investigating this possibility is required.
期刊介绍:
ACTA VETERINARIA BRNO is a scientific journal of the University of Veterinary and Pharmaceutical Sciences in Brno, Czech Republic.
The scientific journal Acta Veterinaria Brno is dedicated to the publication of original research findings and clinical observations in veterinary and biomedical sciences. Original scientific research articles reporting new and substantial contribution to veterinary science and original methods that have not been submitted for publication elsewhere are considered for publication. A written statement to this effect should accompany the manuscript, along with approval for publication by the author´s head of department. The authors bear full responsibility for the contents of their contribution. Book reviews are published, too.
