Five versus more than five years of tamoxifen for lymph node-negative breast cancer: updated findings from the National Surgical Adjuvant Breast and Bowel Project B-14 randomized trial. Based on genetic profiling, breast cancers are divided into five subtypes: luminal A, luminal B, normal breast–like, HER2+, and basal-like carcinomas.Breast cancer is a heterogeneous disease and can be in situ, invasive, or both.Invasive breast cancers are classified by morphology: ductal, lobular, tubular, mucinous, medullary, papillary, metaplastic, and others.Breast cancer subtypes are determined by gene profiling: luminal A, luminal B, normal, HER2+, and basal-like.ER, PR, HER2, and lymphovascular invasion status are important risk factors for relapse.One of the most important discoveries stemming directly from microarray studies has been the reclassification of breast cancer into molecular subtypes. Tubular carcinoma accounts for 3% to 5% of all invasive breast carcinomas. The in situ or noninvasive disease encompasses a spectrum of lesions and is not as simple as the original definition impliesThe conventional pathologic classifications of invasive breast cancers by morphology include invasive ductal carcinoma, invasive lobular carcinoma, tubular carcinoma, mucinous carcinoma, medullary carcinoma, papillary carcinoma, metaplastic carcinoma, and other less common types.
It is a low-grade cancer with an excellent prognosis and usually occurs in older women.Even though genetic profiling has not been widely used in clinical practice, the research on this technology has resulted in a molecular classification of breast cancer with the hope of offering insight on the prognosis and response of tumors to specific therapy. & Sneige, N.

Luminal A : bas grade, RE+++ et de bon pronostic ; sensibles au traitement hormonal seul ; Luminal B : cancers moins bien différenciés et plus proliférants, RE+ et de pronostic un peu moins bon ; sensibles à l’hormonothérapie et à la chimiothérapie . Luminal breast cancer is the most-frequently occurring subtype of breast cancer, but it is a highly heterogeneous disease. Rodon, J., Dienstmann, R., Serra, V. & Tabernero, J. Weinberg, R. A. Creighton, C. J. There are five main intrinsic or molecular subtypes of breast cancer that are based on the genes a cancer expresses: Luminal A breast cancer is hormone-receptor positive (estrogen-receptor and/or progesterone-receptor positive), HER2 negative, and has low levels of the protein Ki-67, which helps control how fast cancer cells grow. Lianidou, E. S. Circulating tumor cells—new challenges ahead. Based upon the original classification described by Perou et al., these subtypes are [In the basal-like subtype, there is a high expression of basal cytokeratins 5/6 and 17 and proliferation-related genes, as well as laminin and fatty-acid binding protein 7. Le traitement du cancer du sein nécessite une coordination étroite entre différentes disciplines médicales et paramédicales car il associe, en fonction des besoins, chirurgie, radiothérapie, chimiothérapie, hormonothérapie et nouveaux traitements ciblés. The conceptual differences between these two systems should be clearly noted when they are used.Breast cancer subtype is associated with local and regional relapse. Cancer Genome Atlas Network.
