BACKGROUND: In response to findings from the Breast Cancer Prevention Trial that tamoxifen treatment produced a 49% reduction in the risk of invasive breast cancer in a population of women at elevated risk, the National Cancer Institute sponsored a workshop on July 7 and 8, 1998, to develop information to assist in counseling and in weighing the risks and benefits of tamoxifen. Our study was undertaken to develop tools to identify women for whom the benefits outweigh the risks. METHODS: Information was reviewed on the incidence of invasive breast cancer and of lesions, as well as on several other health outcomes, in the absence of tamoxifen treatment. Data on the effects of tamoxifen on these outcomes were also reviewed, and methods were developed to compare the risks and benefits of tamoxifen. RESULTS: The risks and benefits of tamoxifen depend on age and race, as well as on a woman's specific risk factors for breast cancer. In particular, the absolute risks from tamoxifen of endometrial cancer, stroke, pulmonary embolism, and deep vein thrombosis increase with age, and these absolute risks differ between white and black women, as does the protective effect of tamoxifen on fractures. Tables and aids are developed to describe the risks and benefits of tamoxifen and to identify classes of women for whom the benefits outweigh the risks. amoxicillin bloating After surgery, women diagnosed with hormone-receptor-positive breast cancer usually take hormonal therapy medicine to reduce the risk of the cancer coming back (recurrence). Hormonal therapy medicines work in two ways: There are several types of hormonal therapy medicines. Tamoxifen, a selective estrogen receptor modulator (SERM), is one of the most well-known. Tamoxifen can be used to treat both premenopausal and postmenopausal women. In the early 2000s, the aromatase inhibitors: were shown to be more effective at reducing recurrence risk in postmenopausal women and are now used more often than tamoxifen to treat women who’ve gone through menopause. Aromatase inhibitors aren’t commonly used to reduce recurrence risk in premenopausal women. Most women take hormonal therapy for 5 to 10 years after breast cancer surgery.

Tamoxifen, on of the most common hormonal therapy drugs, has been shown to decrease the chance of recurrence in some early stage breast cancers and to prevent the development of cancer in the opposite breast. 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. After surgery and other treatments (chemotherapy, radiation therapy), women diagnosed with early-stage, hormone-receptor-positive breast cancer usually take 5 to 10 years of a hormonal therapy medicine to lower recurrence risk (the cancer coming back). When hormonal therapy is used this way, it's called adjuvant hormonal therapy. Of the adjuvant hormonal therapy choices, tamoxifen has been approved the longest and is approved to treat both premenopausal and postmenopausal women. The aromatase inhibitors are the other main type of hormonal therapy medicine and are approved to treat only postmenopausal women. While most women take tamoxifen for 5 or 10 years, it hasn’t been clear if taking tamoxifen for fewer than 5 years offered benefits. During the follow-up period: Overall, women treated with tamoxifen had slightly better survival, no matter the hormone receptor status of the cancer. A Swedish study suggests that taking tamoxifen for 2 years offers long-term survival benefits for premenopausal women diagnosed with early-stage, estrogen-receptor-positive disease compared to no treatment after surgery. For women diagnosed with estrogen-receptor-positive cancer, treatment with tamoxifen: The reduction in risk of dying from breast cancer was statistically significant, which means that it was likely because of the tamoxifen treatment and not just due to chance. The study was published online on May 9, 2016 by the One woman in the tamoxifen group and six women in the no hormonal therapy group were treated with chemotherapy. Women diagnosed with estrogen-receptor-positive disease who were younger than 40 got the most benefits from tamoxifen.
