In clinical trials, there is some evidence that Keytruda may also have a role in treating metastatic HER2 positive breast cancer (along with a HER2 targeted therapy such as Herceptin (trastuzumab) with high PD-L1 and high levels of tumor-infiltrating lymphocytes. Ethoxy mansonone G is the most potent MG derivative and has anticancer effects in ER‐positive, endocrine‐resistant and ER‐negative breast cancer cells. While immunotherapy has been looked at most often as a treatment for metastatic breast cancer, researchers believe it may have a role in the earlier stages of breast cancer as well. This concept involving looking at the tissues surrounding a tumor, or the tumor microenvironment, is currently a topic of great interest in the development of better cancer therapies. Since cells with more mutations should theoretically appear more abnormal, when the immune system is unleashed to attack it should recognize cells with more mutations better than cells containing fewer mutations. The anti-cancer immune…, NLM Tecentriq is most effective in people who have high PD-L1 expression, or a large amount of the PD-L1 protein on the surface of the breast cancer cells. Two clinical trials of PD-1/PD-L1 inhibitors in advanced triple negative breast cancer (TNBC) have been reported, highlighting the clinical importance of immunotherapy in breast cancer. The type of breast cancer you have determines the type of medication you take. Tecentriq is a PD-L1 antibody that works by blocking PD-L1.
