Definition of luminal a breast cancer
WebA biologic subset of breast carcinoma defined by high expression of genes characteristic of luminal epithelial cells, including estrogen receptor (ER), estrogen regulated protein LIV-1, and the transcription factors hepatocyte nuclear factor 3, HNF3A, XBP1, and GATA 3. This subtype of breast cancer is associated with a good prognosis. [from NCI] WebThe age of ≥40 years was a risk factor for luminal B(HER-2+), and a significant correlation was present between the right breast and luminal B(HER-2+).Conclusion: We explored the risk factors of breast cancer laterality and various molecular subtypes and found that age may be a predictor of breast cancer laterality.
