    Tamoxifen test


    The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. PURPOSE: This clinical trial is studying a breath test to see how well it works in women receiving tamoxifen for the prevention or treatment of breast cancer. Listing a study does not mean it has been evaluated by the U. OUTLINE: Patients receive tamoxifen citrate for 6 months. RATIONALE: A breath test that measures enzymes may be effective in identifying women in whom tamoxifen may not be effective. ^13C-dextromethorphan breath tests are conducted at baseline and periodically during the 6 months. 13C-dextromethorphan breath test: Patients receive oral Alka-Seltzer® Gold (ASG; citric acid, potassium bicarbonate, and sodium bicarbonate) in water, then, 15 minutes later, another ASG dose and oral ¹³C-dextromethorphan. Patients breathe into a bag 1-2 times, and the is bag sealed. Blood samples are collected at baseline and periodically for pharmacogenetic and pharmacokinetic studies by reverse phase HPLC with fluorescence detection. After completion of study therapy, patients are followed annually for 5 years. It is usually given as an additional treatment following surgery, to reduce the risk of breast cancer returning in the same breast or a new breast cancer developing in either breast, or spreading somewhere else in the body. If you’re going to take tamoxifen as part of your treatment for primary breast cancer, your specialist will tell you when it’s best to start. Tamoxifen can be used to treat primary breast cancer. It may also be used to reduce the risk of breast cancer developing in women who have a significant family history of breast cancer. Back to top Tamoxifen may be prescribed if you have primary breast cancer, recurrence or secondary breast cancer. Find out more about how male breast cancer is treated. Most breast cancers in men are oestrogen receptor positive. If your cancer is found to be hormone receptor negative, then tamoxifen will not be of any benefit to you.

    Clinical recommendations discouraging the use of CYP2D6 gene testing to guide tamoxifen therapy in breast cancer patients are based on. Genetic testing is available for many ~30 of the variant CYP2D6 alleles. Usually a patient's result is reported as a diplotype. Tamoxifen is a hormonal therapy medicine that is used in several. some doctors and women began to ask for CYP2D6 genetic testing.

    In this study, the researchers looked at more than 1,000 breast cancer tissue samples and did genetic testing on them. They found that more than 40% of the breast cancers had lost one copy of the testing might classify you as someone who produces enough CYP2D6 enzyme when you really don’t, and vice versa. The researchers then looked at samples of normal tissue as well as breast cancer tissue from about 200 women in the NCCTG 89-30-52 trial and did testing may help decide if tamoxifen is a good adjuvant hormonal therapy choice for a specific woman. For women with genotypes that produce low levels of the CYP2D6 enzyme, an aromatase inhibitor might be a better hormonal therapy choice because aromatase inhibitors don't depend on the CYP2D6 enzyme. The aromatase inhibitors are: testing is used to help guide hormonal therapy medicine choices. Still, you might want to talk to your doctor about this study if you're considering tamoxifen treatment or are already taking tamoxifen. It's also important to know that some medicines also can affect how the CYP2D6 enzyme functions and may reduce tamoxifen's effectiveness. Clinical recommendations discouraging the use of CYP2D6 gene testing to guide tamoxifen therapy in breast cancer patients are based on studies with flawed methodology and should be reconsidered, according to the results of a new study. Clinical recommendations discouraging the use of CYP2D6 gene testing to guide tamoxifen therapy in breast cancer patients are based on studies with flawed methodology and should be reconsidered, according to the results of a Mayo Clinic study published in the Journal of the National Cancer Institute. For years, controversy has surrounded the CYP2D6 gene test for breast cancer. Women with certain inherited genetic deficiencies in the CYP2D6 gene metabolize tamoxifen less efficiently, and thus have lower levels of tamoxifen's active cancer-fighting metabolite endoxifen. Numerous studies have shown that these women gain less benefit from tamoxifen therapy and have higher rates of recurrence. However, two large clinical trials found no link between the CYP2D6 genotype and tamoxifen effectiveness, prompting recommendations against testing. In the new Mayo Clinic study, researchers found that previous studies, which used tumor tissue instead of healthy tissue to determine the CYP2D6 genotype, were prone to error.
