    Tamoxifen chemoprevention


    Chemoprevention is a way to prevent or delay the development of cancer by taking medicines, vitamins or other agents. Tamoxifen, the first chemoprevention drug to receive FDA approval, is the most well-known chemopreventive agent. Studies have shown that tamoxifen reduces a high-risk woman’s chances of developing breast cancer by as much as one-half. Some chemopreventive drugs can have severe side effects in some patients, which is an issue when considering long-term administration of a drug to healthy people who may or may not develop cancer. For this reason, most chemopreventive drugs are recommended solely for people at high risk of developing cancer because they are most likely to benefit from treatment. Persons at high risk of developing cancer include those with: Speak with your doctor about your risks for developing cancer, as well as the potential harms and benefits associated with taking chemopreventive agents. Your doctor can help decide if chemoprevention is right for you. propecia acne In order to use Medscape, your browser must be set to accept cookies delivered by the Medscape site.

    Breast cancer is the most common type of cancer in women after nonmelanoma skin cancers, causing significant morbidity and mortality all over the world. In fact, it is estimated that roughly 40,000 women will die from this disease in 2013.1 The average woman in the United States has about a 12% to 13% risk of developing breast cancer in her lifetime. This year 230,000 women will be diagnosed with invasive breast cancer, and about 55,000 will be diagnosed with ductal carcinoma in situ (DCIS). The most significant risks factors for breast cancer are age and family history.1 Although screening for early detection is practiced routinely, providers rarely offer chemoprevention for breast cancer. There is reluctance among clinicians to discuss and implement chemoprevention or prescribe drugs for breast cancer prevention. The US Preventive Services Task Force recommends that high-risk women between the ages of 40 and 70 be assessed for their likelihood of developing the disease and should be offered chemoprevention if they are at low risk of thromboembolic disease and endometrial cancer.2 However, it is important to note that the task force suggests that women aged 60 and older are at high risk of developing complications from chemoprevention, so physicians should use precautions and tailor treatment to each patient’s case. Assessing Risk The Breast Cancer Risk Assessment Tool (also called the Gail Model Risk Assessment Tool), developed by the National Cancer Institute and the National Surgical Adjuvant Breast and Bowel Project (NSABP), helps estimate a woman’s risk of developing invasive breast cancer.3 The tool has been updated for black women based on the Contraceptive and Reproductive Experiences study and for Asian and Pacific Islander women in the United States based on the Asian American Breast Cancer Study.3 The risk assessment tool consists of seven questions (see sidebar on page ••) and can be found as an interactive tool at If you're at high risk of breast cancer, you may be able to improve your odds of staying cancer-free by taking certain medicines, an approach known as chemoprevention or preventive therapy. Medications for breast cancer chemoprevention are the subject of much ongoing research. Tamoxifen blocks the effects of estrogen — a reproductive hormone that influences the growth and development of many breast tumors. Tamoxifen belongs to a class of drugs known as selective estrogen receptor modulators (SERMs), and it reduces the effects of estrogen in most areas of the body, including the breast. In the uterus, tamoxifen acts like an estrogen and encourages the growth of the lining of the uterus. Tamoxifen is prescribed as a pill you take once a day by mouth. For breast cancer risk reduction, tamoxifen is typically taken for a total of five years.

    Half of the women failed to finish a five year course of the drug and one in five regularly forget to take a tablet. Experts already know that taking tamoxifen for five years increases survival chances and the new research reveals that women who miss at least one tablet every five days have a 10 per cent greater risk of dying. The researchers - based at the University of Dundee and funded by the Medical Research Council and Breast Cancer Research (Scotland) - used the prescription records of more than 2000 women to see how many did not complete the standard treatment of a tamoxifen tablet every day and linked this to other health records to see if they were more likely to die. The results show that 10 per cent of women followed for one year stopped taking tamoxifen, 19 per cent of the women followed for at least two years had stopped, 32 per cent of the women followed for three and a half years had stopped and a total of 51 per cent of women followed for five or more years had stopped taking the drug. The study also showed that younger women were more likely to stop taking the medication early but there was no difference in the rich or poorer groups of women. Professor Alastair Thompson, based at Ninewells Hospital Dundee and the senior breast specialist on the study, said: “This study paints a worrying picture. Tamoxifen is prescribed for five years to offer the best chance of surviving breast cancer, and not taking the tablets means that many women could be disadvantaged.
