For some women with breast cancer, taking adjuvant tamoxifen (Nolvadex®) for 10 years after primary treatment leads to a greater reduction in breast cancer recurrences and deaths than taking the drug for only 5 years, according to the results of a large international clinical trial. The findings from the ATLAS trial—presented at the San Antonio Breast Cancer Symposium (SABCS) and published in on December 5, 2012—are likely to change clinical practice, several researchers said. Nearly 7,000 women with early-stage, estrogen receptor-positive breast cancer were enrolled in the trial between 19. After taking tamoxifen for 5 years, participants were randomly assigned to continue taking tamoxifen for another 5 years or to stop taking it. From 5 to 9 years after the women began tamoxifen therapy, there was little difference in outcomes between the two treatment groups. This finding is consistent with those from other trials of adjuvant tamoxifen therapy, which showed that 5 years of tamoxifen can substantially reduce the risk of the cancer returning and of cancer death in the next few years, what one of the trial investigators, Richard Gray, MSc, of Oxford University, UK, called a "carryover effect." The improved outcomes with longer tamoxifen use emerged only after the 10-year mark, Gray explained during an SABCS press briefing. Among the women who took tamoxifen for 10 years, the risk of breast cancer returning between 10 and 14 years after starting tamoxifen was 25 percent lower than it was among women who took it for 5 years, and the risk of dying from breast cancer was nearly 30 percent lower. valtrex versus acyclovir Tamoxifen (Nolvadex) has been used for over 40 years to treat hormone-receptor positive early, locally advanced and metastatic breast cancers. Learn about tamoxifen and other hormone therapies for metastatic breast cancer. Hormone receptor-positive breast cancers need estrogen and/or progesterone (female hormones produced in the body) to grow. Tamoxifen attaches to the hormone receptor in the cancer cell, blocking estrogen from attaching to the receptor.

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). Women who’ve had breast cancer can still get other cancers, although most don’t get cancer again. Breast cancer survivors are at higher risk for getting another breast cancer, as well as some other types of cancer.
