I'm confused
Tricia, there seems to be a lot of confusion when it comes to luminal B, here's a few :-)
luminal B (HR+/HER2+),................this is from ASCO link I quoted above
The following is from a report on Breastcancer.org called "Breast Cancer Risk Factors Vary by Tumor Subtype"......
hormone-receptor-positive (either estrogen- and/or progesterone-positive), HER2-positive breast cancer, called luminal B breast cancer
The following from a report on Breastcancer.org called "ASCO Breast: Analysis Revises Taxane Benefit in Breast Cancer"......
Luminal B tumors are hormone-receptor-positive, HER2-negative, and fast-growing. They were the third most common type of tumor (18%).............
Susan G Komen site:
Luminal B........ER+ and/or PR+, HER2+ (or HER2- with high Ki67) accounts for 6-19%
And this....Luminal B tumors are estrogen receptor and/or progesterone receptor positive, as well as Her2 positive.......... But don't know where I found it!
Lastly on google search:
Luminal B breast tumors are not HER2 positive.
