Distant metastases represent a major step in the progression and fatal outcome of canine and feline mammary carcinomas. Recent studies have characterized the molecular phenotypes of mammary tumours and provided information on molecules that may allow targeted therapy in sites from which the tumours may not readily be surgically resected. Molecular phenotypes were determined immunohistochemically in three feline and two canine cases of mammary neoplasia, each presenting with multiple distant metastases. These tumours and their metastases often overexpressed the c-erbB-2 phenotype. A basal-like phenotype was found in the distant metastases from two cases. These findings suggest that canine and feline mammary tumours with distant metastases may be amenable to novel targeted therapies.

Abstract

Distant metastases represent a major step in the progression and fatal outcome of canine and feline mammary carcinomas. Recent studies have characterized the molecular phenotypes of mammary tumours and provided information on molecules that may allow targeted therapy in sites from which the tumours may not readily be surgically resected. Molecular phenotypes were determined immunohistochemically in three feline and two canine cases of mammary neoplasia, each presenting with multiple distant metastases. These tumours and their metastases often overexpressed the c-erbB-2 phenotype. A basal-like phenotype was found in the distant metastases from two cases. These findings suggest that canine and feline mammary tumours with distant metastases may be amenable to novel targeted therapies.
