The prognostic contribution of clinical breast cancer subtype, age, and race among patients with breast cancer brain metastases.
Summary of "The prognostic contribution of clinical breast cancer subtype, age, and race among patients with breast cancer brain metastases."
Brain metastases (BM) arising from triple-negative breast cancer (TNBC) portend a poor prognosis. TNBC is more common in premenopausal and African-American (AA) patients; both of these characteristics also confer a poor prognosis. In a single-institution cohort study, the authors attempted to determine whether the inferior outcome noted with TNBC brain metastases is more reflective of a higher risk population or the subtype itself.

Inflammatory Breast Neoplasms
Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.
A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)
Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.
Tumors or cancer of the human BREAST.
The phosphoprotein encoded by the BRCA1 gene (GENE, BRCA1). In normal cells the BRCA1 protein is localized in the nucleus, whereas in the majority of breast cancer cell lines and in malignant pleural effusions from breast cancer patients, it is localized mainly in the cytoplasm.

BACKGROUND: Prior study suggests that p53 status behaves as an independent marker of prognosis in African American (AA) women with breast cancer. We investigate whether the influence of p53 is unique...
Gene prognostic meta-analyses should benefit from breast tumour genomic data obtained during the last decade. The aim was to develop a user-friendly, web-based application, based on DNA microarrays re...
PURPOSE: To compare clinical, immunohistochemical and gene expression models of prognosis applicable to formalin-fixed, paraffin-embedded blocks in a large series of estrogen receptor positive breast...
BACKGROUND: Primary breast cancers that overexpress human epidermal growth factor receptor 2 have variable biological features and clinical outcomes. A subgroup of HER2-overexpressing tumors that expr...
To assess the prognostic value of presurgical CA15.3 in a large cohort of patients with early breast cancer. A total of 7.942 consecutive patients with breast cancer operated at the European Institute...
We hypothesize that Simvastatin administration would result in selective killing of the basal subtype of breast cancer, in particular, CD44+/CD24- breast cancer cells in primary tumor. We...
Primary Objectives: 1. To validate the prognostic significance of circulating tumor cells (CTCs) in patients with newly diagnosed metastatic breast cancer (MBC). 2. To pro...
RATIONALE: Biopsy of sentinel lymph nodes and bone marrow may improve the ability to detect and determine the extent of cancer. PURPOSE: Phase III prognostic study of sentinel lymph node...
There is laboratory evidence that cholesterol lowering medications (statins) inhibit the growth of breast cancer cells. Clinical studies are controversial but some show that women taking s...
RATIONALE: Gathering information about the frequency and intensity of hot flashes in patients with breast cancer and in patients who have a high risk of developing breast cancer may help d...
