Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
The National Comprehensive Cancer Network (NCCN) guidelines recommend bilateral prophylactic mastectomy and bilateral salpingo-oophorectomy for women who are carriers of germline BRCA1/2 mutation. At the age of 35 to 40 years, or once childbearing is completed, the procedure is recommended for risk reduction purposes.
The National Comprehensive Cancer Network (NCCN) is an alliance of 33 [1] cancer centers in the United States, most of which are designated by the National Cancer Institute (one of the U.S. National Institutes of Health) as comprehensive cancer centers. It is a non-profit organization with offices in Plymouth Meeting, Pennsylvania.
The Journal of the National Comprehensive Cancer Network, established in 2003, is a monthly peer-reviewed medical journal of oncology and the official journal of the National Comprehensive Cancer Network (NCCN). It is published by Harborside Press and the editor-in-chief is Margaret Tempero (UCSF Helen Diller Family Comprehensive Cancer Center ...
Molecular classification of breast cancer from mRNA expression profiles. DNA microarrays have compared normal cells to breast cancer cells and found differences in the expression of hundreds of genes. Although the significance of many of those genetic differences is unknown, independent analyses by different research groups has found that ...
In February 2007, the U.S. Food and Drug Administration (FDA) cleared the MammaPrint test for use in the U.S. for lymph node negative breast cancer patients of all ages, ER negative or ER positive, with tumors of less than 5 cm. [19] MammaPrint can be considered as a part of standard of care disease management for early stage breast cancer and ...
ER-positive is one of the Receptor statuses identified in the classification of breast cancer.Receptor status was traditionally considered by reviewing each individual receptor (ER, PR, her2) in turn, but newer approaches look at these together, along with the tumor grade, to categorize breast cancer into several conceptual molecular classes [1] that have different prognoses [2] and may have ...
3D medical illustration depicting the TNM stages in breast cancer. Cancer staging can be divided into a clinical stage and a pathologic stage. In the TNM (Tumor, Node, Metastasis) system, clinical stage and pathologic stage are denoted by a small "c" or "p" before the stage (e.g., cT3N1M0 or pT2N0).
