Bei Risikopatientinnen senken Tamoxifen und Raloxifen in gleichem Umfang das Brustkrebsrisiko. Da die beiden Wirkstoffe ein unterschiedliches Nebenwirkungsprofil aufweisen, können bei der Therapiewahl das Risikoprofil und individuelle Patientenwünsche berücksichtigt werden. Zur Prävention von Brustkrebs bei Risikopatientinnen werden selektive Estrogenrezeptor-Modulatoren (SERMs) eingesetzt. Für das ältere Tamoxifen, das auch in der Therapie des hormonrezeptorpositiven Mammakarzinoms angewandt wird, liegen mehrere Studien vor, in denen eine deutliche Abnahme des relativen Brustkrebsrisikos gezeigt wurde, und auch das jüngere Raloxifen, das bislang hauptsächlich in der Osteoporosetherapie eingesetzt wird, verfügt über ein Potenzial zur Vorbeugung von Brustkrebs. In zwei Studien wurden diese beiden Wirkstoffe direkt miteinander verglichen. Die eine Studie befasste sich mit der präventiven Potenz bei Brustkrebs und den Nebenwirkungen dieser Substanzen, die zweite mit der Lebensqualität der Probandinnen unter diesen Therapien.

Dirt cheap viagra For women at higher risk of breast cancer, drugs such as tamoxifen and raloxifene have been shown to help reduce the risk. levitra patient assistance program Both tamoxifen and raloxifene can lower the risk of invasive breast cancer tamoxifen by about 50. Randomized controlled trials of raloxifene versus tamoxifen. Find a comprehensive guide to possible side effects including common and rare side effects when taking Evista Raloxifene for healthcare professionals and consumers. Tamoxifen and raloxifene have been shown to reduce the risk breast cancer, but they can have their own risks and side effects. Tamoxifen and raloxifene are the only drugs that are approved in the US to help lower the risk of breast cancer, although for some women, drugs called aromatase inhibitors might be an option as well. This means that they act against (or block) estrogen (a female hormone) in some tissues of the body, but act like estrogen in others. Estrogen can fuel the growth of breast cancer cells. Tamoxifen can be taken whether or not you have gone through menopause, but raloxifene is only approved for post-menopausal women. Both of these drugs block estrogen in breast cells, which is why they can be useful in lowering breast cancer risk. To lower the risk of breast cancer, these drugs are taken for 5 years. The effect of these drugs on breast cancer risk has varied in different studies. When the results of all the studies are taken together, the overall reduction in risk for these drugs is about 40% (more than a third). These drugs lower the risk of both invasive breast cancer and ductal carcinoma in situ (DCIS). Although a medicine that cuts your risk by about 40% sounds like it must be a good thing, what it would really mean for you depends on how high your risk is in the first place (your baseline risk). If you or a loved one has increased risk factors for breast cancer, developing a risk reduction plan is an important conversation to have with your doctor. At our hospital, we always recommend tackling obesity and alcohol usage first, but for those at high risk, chemoprevention can be a small piece of the risk reduction puzzle. Cancer chemoprevention is the use of drugs, either manufactured or natural, to delay or prevent the diagnosis of cancer. Breast cancer prevention drugs like tamoxifen, raloxifene and aromatase inhibitors (AIs) are the most commonly used drugs for preventative therapy. Chemoprevention does not treat malignant breast cancer if you’ve already been diagnosed. But you might be a good candidate for breast cancer prevention drugs if you have a benign (i.e. non-cancerous) disease that puts you in the high-risk category.
