Researchers Find New Drug To Shrink Breast Cancer Tumors
December 12, 2009Boston (SmartAboutHealth) - Researchers have discovered a new antibody drug that has the ability to shrink breast cancer tumors that other drugs have failed to impact.
The study was carried out by researcher Dr. Ian Krop and colleagues at the Dana Farber Cancer Institute.
What they discovered is that a hybrid drug, T-DM1, was able to shrink or at least stop the growth of HER2-positive breast cancer tumors.
The drug is a combination of the antibody tratuzumab and the drug DM1, which has the ability to kill breast cancer cells.
The way in which the drug works is pretty remarkable, as it has the ability to cling onto and attack only breast cancer cells, not the healthy cells in the body.
The antibody can work in conjunction with chemotherapy, allowing the chemotherapy to work while not harming the rest of the body.
During the study, they found that the drug was effective in treating 40% of women who have the HER2-positive breast cancers.
The tumors were shrunk by a margin of 30% or more when it was used.
The drug was also found to stabilize the breast cancer tumors at a high rate as well.
The new drug was presented at the 32nd annual CTRC-AACR San Antonio Breast Cancer Symposium.

Treatment - pelvic floor treatments
Work by Wise and Anderson (see details) has shown that urologic pelvic pain syndromes, such as IC/PBS and CP/CPPS, may have no initial trigger other than anxiety, often with an element of Obsessive Compulsive Disorder or other anxiety-spectrum problem. This is theorized to leave the pelvic area in a sensitized condition resulting in a loop of muscle tension and heightened neurological feedback (neural wind-up). This is a form of myofascial pain syndrome. Current protocols ...Section: Interstitial cystitis
