Barron’s Medical Journal Reporting from The University Of Texas Medical School Houston, Texas USA
Houston ( AP ) Barron’s Medical Journal is at The University of Texas Medical School to bring you the latest in breast cancer research. Yes there is a new kid on the block for breast cancer Perjeta.
Perjeta was only used for Women that had stage four breast cancer and now thanks to millions of dollars spent on breast cancer research the FDA has approved Perjeta to be use in Stage one breast cancer. This is fantastic news and the power of genomics science what use to take years now companies like Roche and other are using genomic to speed up their research.
United States (U.S.) Food and Drug Administration (FDA) granted accelerated approval of a Perjeta (pertuzumab) regimen for neoadjuvant treatment (use before surgery) in people with high-risk, HER2-positive early stage breast cancer. This approval is based primarily on data from a Phase II study showing that
nearly 40 percent of people receiving the combination of Perjeta, Herceptin (trastuzumab) and docetaxel chemotherapy had no evidence of tumour tissue detectable at the time of surgery (known as a pathological complete response, or pCR). The Perjeta regimen is the first neoadjuvant breast cancer treatment approved by the FDA and also the first to be approved based on pCR data.
The approval of pertuzumab for neoadjuvant treatment of breast cancer is based on a randomized, multicenter, open-label trial in patients with HER2-positive, operable, locally advanced or inflammatory breast cancer
Pertuzumab, trastuzumab, and docetaxel were administered preoperatively by intravenous infusion (IV) every 3 weeks for a total of 4 cycles. Following surgery all patients received 3 cycles of fluorouracil,
epirubicin, and cyclophosphamide (FEC) IV every 3 weeks and trastuzumab was administered IV every 3 weeks to complete 1 year of therapy. The trial’s primary endpoint was pathologic complete response (pCR) rate defined as the absence of invasive cancer in the breast (ypT0/is). The FDA-preferred definition of pCR is the absence of invasive cancer in the breast and lymph nodes (ypT0/is ypN0).
PERJETA is a sterile, clear to slightly opalescent, colorless to pale brown liquid for intravenous infusion. Each single use vial contains 420 mg of pertuzumab at a concentration of 30 mg/mL in 20 mM L-histidine acetate (pH 6.0), 120 mM sucrose and 0.02% polysorbate 20.
Some breast cancers have large amounts of a protein called HER2 on the surface of the cells. These cancers are ‘HER2 positive’ and can be treated with a drug called trastuzumab which targets the HER2 protein. You may have trastuzumab with chemotherapy. Paclitaxel anddocetaxel are drugs that doctors often use.
Sam Houston Biotech A Houston Based cancer Research Organization has found that genomic science has advanced. Sections of microarray provide targets for parallel in situ detection of DNA, RNA and protein targets in each specimen on the array. The better News is that Genomics is on the Clock. Genomics provide a faster cheaper more effective way to detect the Her2 gene by using Semiconductor Sequencing. A example of this technique is Gennxeix Biotech Inc Semiconductor Sequencing. "Quantum Theory" In Action for Breast Cancer Patients. One of the major player and touch down makers for breast cancer is Houston Texas Methodist Hospital. 
In A clinical Trial A Rev. Noel Denison, a retired Methodist minister, was diagnosed with locally advanced HER2-positive breast cancer and is enrolled in the study at Methodist, one of only two locations in the United States. The clinical trial is for locally advanced or metastatic HER2-positive breast cancer and combines standard chemotherapy with trastuzumab emtansine, better known in the breast cancer world as T-DM1, and pertuzumab, a monoclonal antibody that also attaches to HER2 on cancer cells. Using Genomics and semiconductors to detect breast cancer plus T-DM1 to treat breast cancer is a winning combination. What is T-DM1? T-DM1 is in a new class of cancer-fighting agents called antibody drug conjugates. By combining the antibody trastuzumab directly with docetaxel (standard chemotherapy) and/or pertuzumab, the T-DMI is designed to attack the tumor cells directly and deliver the chemotherapy. Trastuzumab emtansine (T-DM1) consists of our proprietary DM1 cancer-killing agent attached to the HER2-binding antibody, trastuzumab, developed by Genentech (a member of the Roche Group) using our linker and methods of attachment. Trastuzumab emtansine is in global development by Roche under a collaboration agreement between ImmunoGen and Genentech. Marketing applications for trastuzumab emtansine are under review in the US and Europe. The Defense and the most dangerous aspect of breast cancer is its ability to spread to distant sites, most tumors are initially unable to do that Learning more specifically what triggers metastases may provide additional targets for preventing and treating the malignant process that causes cancer deaths.
It’s widely accepted that cancers acquire the ability to spread through the gradual accumulation of genetic changes, and experiments have also shown that these changes occur in parallel with changes in the protein content and 3-dimensional patterning of the protein meshwork that creates their immediate surroundings Gene that stops the growth of KCNK9 Genes is gene is p53. p53 is a fundamental determinant of cancer susceptibility, p53 integrates stress signals and elicits apoplectic responses that maintain genomic stability. When cells sense a decrease in oxygen availability (hypoxia), they develop adaptive responses in order to sustain this condition and survive. If hypoxia lasts too long or is too severe, the cells eventually die. Hypoxia is also known to modulate the p53 pathway, in a manner dependent or not of HIF-1 (hypoxia-inducible factor-1), the main transcription factor activated by hypoxia. The p53 protein is a transcription factor, which is rapidly stabilized by cellular stresses and which has a major role in the cell responses to these stresses. This process is why it is important Conrad says for people that are first degree relatives of breast cancer patients, must take a genomic test to see if they are the carrier of gene KCNK9. By identifying this gene we can direct patients with the correct advise as to deal with the fact that they have a lunp on the breast to they are going to get a lump on their breast. Often what happens is that a breast cancer patients dose not go to the doctor or take important test to see if there is a lump on the breast. what happens is the spread of breast cancer is responsible for more than 90 percent of breast cancer deaths.
Pertuzumab is a type of biological therapy called a monoclonal antibody. It works by targeting the HER2 protein but in a different way to trastuzumab. We know from research that having both pertuzumab and trastuzumab together may be better than having just one of them alone.
TDM1 is a combination of trastuzumab and a chemotherapy drug called DM1. Trastuzumab finds the cancer cells and delivers the 
DM1 to them. This type of drug is called a conjugated monoclonal antibody.
It is clear to Barron’s Medical Journal first year oncologist will have a new way of treating breast cancer all before the end of President Obama second Term
