Active surveillance vs surgery in adults with low risk thyroid cancer
The concept of monitoring small, low risk thyroid cancers with ultrasound instead of opting for immediate surgery, called active surveillance, was introduced in Japan. Research data on long-term outcomes, however, is scant. This study reports on the long-term experience with active surveillance for papillary thyroid microcarcinoma in Japan.

Patients electing active surveillance for low-risk papillary thyroid cancer have lower baseline anxiety
Recent data shows that small cancers (<1 cm) are usually low risk for growing and spreading. Active surveillance, or following the nodule by ultrasound rather than moving to immediate surgery, is becoming an acceptable option in the management of small low-risk papillary thyroid cancer .This study was done to compare the quality of life over time of patients who chose active surveillance and those who chose immediate surgery for small, low risk papillary thyroid cancer.

How do we make better shared-decisions for thyroid cancer?
Over the years, there has been more involvement of the patient in discussions to determine the best treatment option, a process known as “shared-decision making”. To make this happen in the best possible way, we need to understand the factors that influence the decisions for both the patients and doctors. This study wanted to find out which are the most important of these factors and suggest ideas for better decision making tools for patients with low-risk thyroid cancer.

Excellent survival in younger children compared to adolescents and young adults despite having more advanced papillary thyroid cancer
Papillary thyroid cancer often presents with more aggressive disease in children as compared to than in adults. Despite this more advanced presentation, survival rate in children is higher than in adults with similar disease. This study was done to further look at the relationship between papillary thyroid cancer recurrence vs age in the pediatric population and to compare this to a young adult population.

The risk of thyroid cancer is higher than previously thought when thyroid biopsies show uncertain results
In about 10-20% of thyroid biopsies, a diagnosis cannot be made and the results are called indeterminate. There are three types of indeterminate biopsies, called Bethesda 3, Bethesda 4 and Bethesda 5, with the risk of cancer ranging from 12-52%. This study reviewed recent data to determine if these risks have changed.

How common is thyroid storm and which groups have the highest rates of death from this condition?
Thyroid Storm is the most severe form of hyperthyroidism and can be life-threatening. To learn more about this condition and how it affects different populations, this study was conducted using a large database of medical claims from Germany to estimate how often thyroid storm occurs and the likelihood of survival for those who experience it.
