An approach to malignant mammary phyllodes tumors detection.
BACKGROUND/AIM Mammary phyllodes tumors (MPT) are uncommon fibroepithelial (biphasic) neoplasms whose clinical behavior is difficult to predict on the basis of histological criteria only. They are divided into benign, borderline malignant and malignant groups. Sometimes it appears difficult to distinguish these tumors from other types of soft tissue sarcomas. Because of the relatively scant dat...
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 ...
متن کاملMTA1 Expression in Benign and Malignant Salivary gland Tumors
Introduction: Salivary gland tumors (SGTs) are important parts of human neoplasms. The most common SGT is pleomorphic adenoma and the most common malignant SGTs are mucoepidermoid carcinoma and adenoid cystic carcinoma (ACC). Metastasis-associated genes 1 (MTA1), a member of the nucleosome remodeling and histone deacetylation complex, is one newly discovered gene which recruits histone deacetyl...
متن کاملExpression of autophagy-related protein beclin-1 in malignant canine mammary tumors
BACKGROUND Autophagy is a self-catabolic mechanism that degrades unnecessary cellular components through lysosomal enzymes. Beclin-1, an autophagy-related protein, establishes the first connection between autophagy and tumorigenesis. The purpose of this study is to assess the Beclin-1 expression pattern and to determine its prognostic significance in patients with malignant canine mammary tumor...
متن کاملPatterns of p53 expression in phyllodes tumors of the breast--an immunohistochemical study.
Authors performed an immunohistochemical analysis using monoclonal antibody to p53 protein on 15 cases of benign and malignant phyllodes tumor of the breast along with a review of other conventional clinicopathological parameters to investigate the meaning of p53 expression. The cases were composed of 8 benign and 7 malignant lesions. The pattern of p53 expression showed a statistically signifi...
