1. Metronomic chemotherapy in the neoadjuvant setting: results of two parallel feasibility trials (TraQme and TAME) in patients with HER2+ and HER2− locally advanced breast cancer
Neoadjuvant chemotherapy has practical and theoretical advantages over adjuvant chemotherapy strategy in breast cancer (BC) management. Moreover, metronomic delivery has a more favorable toxicity profile. The present study examined the feasibility of neoadjuvant metronomic chemotherapy in two cohorts [HER2+ (TraQme) and HER2− (TAME)] of locally advanced BC

2. CLASSIFICAÇÃO DE TECIDOS DA MAMA A PARTIR DE IMAGENS MAMOGRÁFICAS EM MASSA E NÃO MASSA USANDO ÍNDICE DE DIVERSIDADE DE MCINTOSH E MÁQUINA DE VETORES DE SUPORTE / CLASSIFICATION OF TISSUE BREAST FROM MAMMOGRAPHIC IMAGES IN MASS AND NOT MASS USING INDEX OF DIVERSITY OF MCINTOSH AND SUPPORT VECTOR MACHINE
O câncer de mama é o segundo tipo de câncer mais frequente no mundo e o que mais acomete as mulheres. Nos últimos anos, vários Sistemas de Detecção e Diagnóstico auxiliados por Computador (Computer Aided Detection/Diagnosis) têm sido desenvolvidos no intuito de auxiliar especialistas da área da saúde na detecção e diagnóstico de câncer, servin

3. Tipos especiais histológicos de carcinomas da mama : perfil imunoistoquímico com ênfase na classificação molecular / Histological special types of breast carcinomas : immunohistochemical profile with emphasis on molecular classification
Most invasive breast carcinomas are classified as invasive ductal carcinoma, not otherwise specified (IDC-NOS), while approximately 25% are defined as special histological types (HST). These HST of breast carcinomas are categorized into at least 17 distinct pathological entities. Most studies in the literature regarding the molecular classification (luminal

O câncer é um dos maiores problemas de saúde mundial, sendo o câncer de mama o que mais causa óbito entre as mulheres e o segundo tipo mais freqüente no mundo. As chances de uma paciente sobreviver ao câncer de mama aumentam à medida que a doença é descoberta mais cedo. Diversos Sistemas de Detecção e Diagnóstico auxiliados por computador (Compu

5. Explorando informações texturais das visões crânio-caudal e médio-lateral oblíqua para extração e classificação Fuzzy de imagens mamográficas / Explorando informações texturais das visões crânio-caudal e médio-lateral oblíqua para extração e classificação Fuzzy de imagens mamográficas
The computerized system to support detection and diagnosis (Computer Aided Detection or Diagnosis - CAD) is a tool for medical help that has been used to identify and diagnose abnormalities in breast tissue. Although CAD systems have provided a large number of research and increased sensitivity, the majority analyzes the MLO and CC views independently. Exper

6. Densidade mamográfica antes e após o uso de tibolona: auxílio da informática / Mamographic Density Before and After the Use of Tibolone: Computer Help
Over the last few years, hormonal therapy has been subject of much controversy since various studies have shown contradictory results regarding the risks and benefits for users. A higher incidence of breast carcinoma among users of classical hormonal therapy has been demonstrated in some studies and therefore there is a constant search regarding the refineme

7. Estudo clÃnico-patolÃgico dos papilomas intraductais centrais e perifÃricos da mama
Aiming to detail the clinical-pathologic characteristics of central and peripheral papillomas, diagnosed in breast tissue gotten by setorectomia or excisional biopsy, a retrospective, descriptive study was performed based on the analysis of anatomopathological reports of these materials, archived at Pathology Department of Hospital de Cancer da ParaÃba - Na

8. Expressão de PRSS11, MTSS1, CLPTM1, SMYD2, NOTCH1 e RPL37A em fatias de carcinoma de mama de cadelas e correlação com resposta à doxorrubicina in vitro / Expression of PRSS11, MTSS1, CLPTM1, SMYD2, NOTCH1 and RPL37A in slices of bitch mammary cancer and correlation with response to exposure doxorubicin in vitro
Mammary gland tumors are the most common neoplasias of bitches and doxorubicin is one the mainstay drugs used in their treatment. Neoadjuvant chemotherapy with doxorubicin not only reduces the primary tumor as well as allows an in vivo evaluation of tumor response. Predictive markers of response, if identified, might allow a tailored treatment of each patien

9. DNA ploidy, nuclear grade and architectural changes in ductal carcinoma in situ and in invasive female breast cancer: a contributory study for the model of disease progression / Ploidia de DNA, grau nuclear e alterações arquiteturais no carcinoma in situ e no carcinoma ductal invasivo da mama feminina: uma contribuição para o estudo do modelo de progressão de doença
Carcinogenesis is a multiple stage phenomenon. Epidemiologic evidence indicates that progression to invasive breast cancer begins in hyperplastic states of the epithelium passing by in situ carcinoma. The actual relationship that exists between ductal carcinoma in situ and invasive ductal carcinoma of the breast and the factors that lead to the tumor invasio

10. Observer variability in reporting of breast lesions.
The consistency of histological diagnosis of breast lesions by members of the panel was studied using a simplified six point classification system that covered the range from normal tissue to invasive carcinoma. In a representative set of 40 sections of the range of breast disease included in the Trial for Early Detection of Breast Carcinoma (the consecutive

11. Repeated observation of breast tumor subtypes in independent gene expression data sets
Characteristic patterns of gene expression measured by DNA microarrays have been used to classify tumors into clinically relevant subgroups. In this study, we have refined the previously defined subtypes of breast tumors that could be distinguished by their distinct patterns of gene expression. A total of 115 malignant breast tumors were analyzed by hier

12. Immunohistochemical differentiation between primary adenocarcinomas of the ovary and ovarian metastases of colonic and breast origin. Comparison between a statistical and an intuitive approach.
AIM: To discriminate between adenocarcinomas that are primary to the ovary and metastatic to the ovary, especially of colonic and breast origin, by immunohistochemistry, using stepwise discriminant analysis or a decision tree. METHODS: 312 routinely processed, formalin fixed tissue specimens were used. The tumours were divided into a learning set (n = 159),
