Roche announced today that it will present the results of studies of pertuzumab, its experimental drug against breast cancer, HER2-positive during the 34th Annual Symposium on CTRC-AACR Breast Cancer to be held in San Antonio from December 6 to 10, 2011 (San Antonio Breast Cancer Symposium, SABCS). Among these results are data from the first randomized phase III study of pertuzumab plus trastuzumab and chemotherapy with docetaxel (CLEOPATRA). The mechanisms of action of pertuzumab and trastuzumab are assumed to be complementary because each molecule binds to the HER2 receptor, but different regions.
Monoclonal antibody studied for the treatment of HER2-positive early stage and metastatic pertuzumab is an experimental molecule targeting the HER2 protein, it blocks the dimerization (inhibitor of HER2 dimerization = HDI). HER dimerization (addition of two elements) is suspected to play an important role in the growth and the formation of several different types of cancer. Pertuzumab is the first Triactol experimental molecule specifically developed to prevent the pairing of HER2 with other HER receptors (EGFR/HER1, HER3, HER4). Through this mechanism of action, pertuzumab is supposed to block the transmission of cellular signals, which should inhibit the growth of cancer cells or cause their death. Binding of pertuzumab in HER2 may also signal the immune system to destroy cancer cells. The mechanisms of action of pertuzumab and trastuzumab are assumed to be complementary because each molecule binds to the HER2 receptor, but different regions. The combination of pertuzumab to trastuzumab and chemotherapy is to determine whether such combination therapy could lead to a more complete blockade of the HER signaling pathway.
Trastuzumab, when with him, is a humanised antibody designed to target and block the function of HER2, a protein produced by a specific gene with cancer-causing potential. The mode of action of trastuzumab is unique in that it activates the body’s immune system and suppresses HER2 to target and destroy the tumor. Trastuzumab has demonstrated its therapeutic effectiveness unmatched in HER2-positive early stage so that advanced stage (metastatic) and in stomach cancer HER2-positive advanced (metastatic). Monotherapy or in combination – simultaneously or sequentially – to standard chemotherapy, trastuzumab has proven to improve progression-free survival, overall survival and response rates, while maintaining the quality of life of people with cancer HER2-positive breast and stomach cancer.

  It is essential to rid our system of harmful toxins that accumulate as a result of an unhealthy eating habits, environmental pollution and chemical compounds, and a frequent use of antibiotics. The air we breath has oxygen in it. It has been identified that fish oils are extremely useful in attempting to keep breast cancer absent in girls who have crossed their menopause.

You could say that I am a bit of a health nut. Almond seeds are non-toxic, and they do not represent a risk to your health in any way, nevertheless, there have been instances when the association with superior dosages of vitaminic aspect C has led to cyanide poisoning. Is it not best to locate a lump the dimensions of pea than that of a person which has created greater in size? Not all breast lumps are cancerous, breast abnormalities should be checked out sooner than later. This means that the anti-cancer therapy with vitamin B17 has obtained rather a lot of detrimental publicity. Linkvana 2.0
