New evidence-based recommendations from the American Thyroid Association (ATA) provide guidance to clinicians in diagnosing and managing thyroid disease during pregnancy and the postpartum period. Pregnancy has a profound effect on thyroid gland function, and thyroid disease is common in pregnancy. The 97 recommendations presented in the new Guidelines help define current best practices for thyroid function testing, iodine nutrition, pregnancy complications, and treatment of thyroid disease during pregnancy and lactation. The American Thyroid Association (ATA) guidelines are available free on the website of Thyroid, the official peer-reviewed journal of the ATA, published by Mary Ann Liebert, Inc., publishers.

The “2017 Guidelines of the American Thyroid Association for the Diagnosis and Management of Thyroid Disease during Pregnancy and the Postpartum” were coauthored by an international task force of expert clinicians and researchers in the field of thyroidology. Led by Co-chairs Erik Alexander MD, Brigham and Women’s Hospital and Harvard Medical School, Boston, MA and Elizabeth Pearce, MD, MSc, Boston University School of Medicine, the task force provides a solid foundation of knowledge on the assessment and treatment of thyroid disease in women during pregnancy, preconception, and the postpartum period. The Guidelines include recommendations related to the diagnosis and management of hypothyroidism, thyrotoxicosis, thyroid nodules, and thyroid cancer, as well as thyroid considerations in infertile women, fetal and neonatal considerations, and directions for future research.

“These guidelines provide a superb overview on the pathophysiology and the clinical management of thyroid disorders during and after pregnancy. In addition, they also define areas where additional research is needed; this will allow keeping the document living with further updates in the coming years,” says Peter A. Kopp, MD, Editor-in-Chief of Thyroid and Professor of Medicine, Division of Endocrinology, Metabolism, and Molecular Medicine, Northwestern University Feinberg School of Medicine, Chicago.

“Produced by an international panel of recognized experts, these updated guidelines add to the library of similar documents on thyroid disease that serve as the gold standard for diagnosis and management of thyroid disorders and identify critical areas where more research and knowledge is needed,” says, John C. Morris, III, MD, President of the ATA, Mayo Clinic, Rochester, MN.

“With an estimated 300,000 pregnancies impacted by thyroid disease in the United States annually, these guidelines coalesce the best available evidence into clear clinical recommendations, and will improve the health of many, many mothers and newborns alike,” say Dr. Alexander and Dr. Pearce.

Recently, several media outlets have reported that mammography and X-rays increase the risk of thyroid cancer. The statements, circulated during the Brazilian " Rosa October ", which is the breast cancer awareness month in Brazil, generated many doubts and concerns about the need to use a thyroid protector during mammography.

 

Thus, we have to reaffirm that there are no consistent studies or statistics demonstrating that a woman undergoing mammography has a higher risk of thyroid cancer. There might be other factors involved in the increased rate of this type of tumor, such as environmental factors. Several published studies show that mammography does not expose the thyroid to harmful X-rays doses. The radiation dose to the thyroid during a mammogram is extremely low, less than 1% of the dose received by the breast, and the radiation emitted by the environment at the time of the examination is higher than this dose.

LATS points out that the use of a thyroid protector is not recommended for mammography. This position is in agreement with other national entities (Brazilian College of Radiology, Brazilian Society of Mastology and the Brazilian Federation of Gynecology and Obstetrics Associations) and international institutions such as the American College of Radiology, American Society for Breast Disease, American Thyroid Association and International Atomic Energy Agency.

"It is important to perform routine screening, such as mammography from the age of 40, which is the most important way to detect early breast cancer. There is no reason to say that mammography causes a thyroid cancer, "concludes LATS President Denise Carvalho.
