The effectiveness of a specific treatment is demonstrated for a specific breast cancer usually by randomized, controlled trials. Among many immunohistochemical tests that may further stratify prognosisBCL2 has shown promise in preliminary studies. N Engl J Med.

Acquiring extensive Level I evidence would be clinically and ethically challenging. Posted October 17, accessioned Dec 19 and July 03 at http: For example, if clinical staging reveals stage IV disease, extensive surgery may not be helpful, and appropriately incomplete pathological staging information will be obtained.

Vxn treatment may not be effective in a different breast cancer. CT appraisal of anatomic distribution”.

Some breast cancers are aggressive and life-threatening, and must be treated with aggressive treatments that have major adverse effects. In addition to that prognostic role, a higher RS is also associated with a higher probability of response to chemotherapywhich is termed a positive predictive factor. Major importance of the mitotic count as a component of both grading systems”.

In cancer, there is a breakdown of the mechanisms that cells use to attach to each other and communicate with each other, to form tissues such as ducts, so the tissue structures become less orderly.


AJCC; [17] original pages Higher-grade tumors are treated more aggressively, and their intrinsically worse survival clsaificacion may warrant the adverse effects of more aggressive medications.

Male breast cancer Inflammatory breast cancer. J Clin Oncol ; Nat Rev Clin Oncol. The major categories are the histopathological type, the grade of the tumor, the stage of the tumor, and the expression of proteins and genes.

The grading of a cancer in the breast depends on the microscopic similarity of breast cancer cells to normal breast tissue, and classifies the cancer as well differentiated low-grademoderately differentiated intermediate-gradeand poorly differentiated high-gradereflecting progressively less normal appearing cells that have claeificacion worsening prognosis.

Since high risk features may already be evident in many high risk cancers, for example hormone-receptor negativity or HER-2 positive disease, the Oncotype test may especially improve the risk assessment that is derived from routine clinical variables in intermediate risk disease.

Also potentially dissimilar treatment. The purpose of classification is to select the best treatment.

Breast cancer classification

In contrast, modern DNA analyses are increasingly relevant in defining underlying cancer biology and in helping choose treatments. Comparative oncogenomics identifies breast tumors enriched in functional tumor-initiating cells”.

There is some evidence that breast cancers that arise in familial clusterssuch as Hereditary breast—ovarian cancer syndromemay have a dissimilar prognosis.

Archived from the original on Histopathologic classification is based upon characteristics seen upon light microscopy of biopsy specimens. The receptor status of breast cancers has traditionally been identified by immunohistochemistry IHCwhich stains the cells based on the presence of estrogen receptors ERprogesterone receptors PR and HER2.

Breast cancer classification – Wikipedia

California Technology Assessment Forum. Well differentiated is given a grade of 1, moderate is grade clasifiacion, while poor or undifferentiated is given a higher grade of 3 or 4 depending upon the scale used. Oncotype DX assesses 16 cancer-related genes and 5 normal comparator reference genes, and is therefore sometimes known as the gene assay.


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 gradeto categorize breast cancer into several conceptual molecular classes [33] that have different juys [11] and may have different responses to specific therapies.

Tumours of the Breast and Female Genital Organs. Advances in Anatomic Pathology.

New Se Journal of Medicine. These methods, and scoring systems that used DNA ploidyare used much less often now, as their predictive and prognostic power was less substantial than other classification schemes such as the TNM stage.

Ductal carcinoma in situ DCIS: Although the significance of many of those genetic differences is unknown, independent analyses by different research groups has found that certain groups of genes have a tendency to co-express. British Journal of Cancer ; This remains the most common method of testing for clasificaxion status, but DNA multi-gene expression profiles can categorize breast cancers into molecular subtypes that generally correspond to IHC receptor status; one commercial source is the BluePrint test, as discussed in the following section.
