Ultrasonographic Evaluation of Mammary Tumors in Bitches
The aim of this study was to characterize the ultrasonographic patterns of benign and malignant mammary tumors and to evaluate the efficacy of ultrasonographic imaging to distinguish benign and malignant tumors in dogs. Shape, margins, width-to-craniocaudal (CC) dimension ratio, echotexture, echogenicity, presence of calcification, presence of pseudocapsule, size (the deepest and longest axis) ...
متن کاملSpontaneous metastasis from primary C3H mouse mammary tumors.
The normal incidence of metastasis was determined in 207 C3H/He and 42 C3Hf/He mice with spontaneous mammary tumors. The effects of early versus delayed surgical removal of the tumors on the incidence of metastasis were studied in the C3H/He mice. The presence of metastases was determined by histological examination, primarily of the lungs. The incidence of metastasis was proportional to the si...
متن کاملAssay of spontaneous and transplanted mammary tumors for the mammary tumor agent.
The mammary tumor agent, one of the primary causes of mammary cancer in mice (5, 6), has the characteristics of an infectious agent or virus. The presence of the agent in infected hosts may be demonstrated by making extracts of either normal or cancerous tissues and injecting these into susceptible animals which do not carry the agent. It has been assumed that the percentage of mice developing ...
متن کاملGene expression profiles of progestin-induced canine mammary hyperplasia and spontaneous mammary tumors.
Spontaneous mammary tumors are the most prevalent type of neoplasms in women as well as in female dogs. Although ovarian hormones estrogen and progesterone are known to play a key role in mammary tumorigenesis, conflicting reports have been obtained from in vivo and in vitro studies concerning the role of especially progesterone in mammary tumorigenesis. Prolonged exposure to high concentration...
متن کاملClassification and grading of canine malignant mammary tumors
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 ...
