American Thyroid Association (ATA): Annual Meeting

DENVER – The malignancy risk of thyroid nodules can be assessed with reassuring accuracy using ultrasound and the guidelines developed by the American Thyroid Association.

Ultrasound assessment is the first step of the evaluation of any patient with one or more thyroid nodules. “Maybe it shouldn’t be, but, for now, it is,” noted David L. Steward, MD, at the annual meeting of the American Thyroid Association.

The ATA guidelines categorize thyroid nodules on the basis of their ultrasound patterns, with the high risk of malignancy being in nodules that are taller than they are wide and /or have microcalcifications, irregular margins, hypoechoic areas, extrathyroidal extension, interrupted rim calcification with soft tissue extrusion, and suspicious lymph nodes. Between 70% and 90% of thyroids with such patterns will contain malignancy, according to the ATA guidelines. Lesions with an intermediate risk of malignancy have such sonographic findings as hypoechoic solid tissue and regular margins; between 10% and 20% of these are malignant. The third category in the ATA’s guidelines are those that are of low suspicion, with hyperechoic solid tissue, isoechoic solid tissue, partially cystic with eccentric solid area, and regular margins; 5%-10% of these are malignant. Thyroid nodules with a very-low risk of malignancy (less than 3%) are spongiform or partially cystic with no suspicious findings. Finally, benign nodules, of which less than 1% contain malignancy, are cysts, he said.

“We found that the size of the nodule on ultrasound that underwent fine needle aspiration was inversely correlated with malignancy risk: The lower risk nodules were larger,” he said.

Using the ATA’s system, 9 (4%) of the nodules were high risk, 64 (31%) were intermediate risk, 79 (38%) were low risk, 54 (26%) were very-low risk, and none were benign. Five of the nodules were not included in the results presented.

There was good correlation between the Bethesda and ATA classification systems. Of the lesions that were malignant or suspicious for malignancy in the Bethesda system, 77% were very-high risk for malignancy on ultrasound according to the ATA. Of the lesions that were atypia of undetermined significance (AUS)/follicular lesion of undetermined significance (FLUS), 22% were very high risk according to the ATA. Neither of the systems classified as malignant any of the lesions as follicular/Hurthle cell cancer, benign, or nondiagnostic.

The AUS/FLUS nodules “tend to be all over the map,” he noted. Looking at just the AUS/FLUS nodules, malignancy was found on pathology in 100% classified by the ATA system as being high risk; in 21% of those called intermediate risk; in 17% of those called low risk; and in 12% of the very-low risk group.

The study was funded by the University of Cincinnati. Dr. Steward said his only disclosure is that he was a member of the ATA committee that wrote the guidelines under evaluation in this study.

DENVER – An alarming percentage of infants born in Utah from 2006 to 2015 with primary congenital hypothyroidism were either lost to follow-up or inadequately treated.

If such a thing can happen in Utah with its highly functioning public health system, it probably can happen in the rest of the United States as well, Joel Ehrenkranz, MD, said at the American Thyroid Association annual meeting. “We just have not looked for it yet.”

Screening for and treating congenital hypothyroidism in infants is one of the great public health successes of the 20th century in the United States. It deserves to have the same level of importance as eradication of polio and smallpox in this country, noted Dr. Ehrenkranz, an endocrinologist in private practice in Glenwood Springs, Colo. At the time of this research, Dr. Ehrenkranz was with Intermountain Healthcare in Murray, Utah.

The American Academy of Pediatrics recommends diagnosis of congenital hypothyroidism by the 14th day of life and that the baby be biochemically euthyroid by week 6 (Pediatrics. 2006 June. doi: 10.1542/peds.2006-0915), he said.

The cohort included 4,394 children from birth to 24 months of age. The screening test was done by a third-generation bioluminescence serum TSH assay, not dried blood blot. Of these infants, 2% (82 babies) had a TSH level greater than or equal to 20 mIU/L at their initial test. That TSH was still high by day 14 in 42 infants (23 girls). But of all the babies with primary congenital hypothyroidism, 50% had a delayed diagnosis, he reported.

Twelve children (15%) were never retested; 34% reached AAP goals of having a TSH level less than 5 mIU/L within 28 days after starting treatment; half of the children with primary congenital hypothyropidism did not meet the treatment goal: “They were inadequately treated,” he said.

Of particular interest were 16 infants who had a TSH level of less than 20 mIU/L but on retesting had one of 20 or higher. Three of these infants had multiple TSH levels greater than 20, perhaps representing a subset with a late onset form of the disorder.

“We are not doing as well as we could do,” he said; 50% of affected babies have a delayed diagnosis with consequences of a delayed maturation of the pituitary thyroid axis. Logistics are a challenge. And 50% of babies did not meet treatment guidelines.

In comparison to the state of screening and management in Utah, moderator Alex S. Stagnaro-Green, MD, noted that many pediatricians and endocrinologists operate under the presumption that screening for primary congenital hypothyroidism is “a well-oiled machine and that these babies are being taken care of.”

Utah has a very functional public health infrastructure. Of note, Utah’s birth rate is the highest in the country. The birth rates in several of its counties rival the highest rates found in the world, according to Dr. Ehrenkranz.

“So I think we have a very significant problem nationwide that just hasn’t been looked at,” he noted in response to the question. He undertook looking at newborn TSH levels in the first place as part of a project with the Food and Drug Administration. It was only then that he and his associates were struck by how many babies had low serum TSH levels, he said.

He had no relevant financial relationships to disclose.

DENVER – Undergoing percutaneous coronary intervention (PCI) may impair thyroid function and change the gland’s morphology, probably because of the cumulative effects of handling and exposure to radiation and iodine in the contrast dye, Samir Naim Assaad, MD, said during a poster presentation at the annual meeting of the American Thyroid Association.

Cardiologists should inform their patients of these possible effects as part of their pre- and post-PCI counseling so that they won’t be alarmed by the changes in how they feel, Dr. Assaad, chief of the division of endocrinology at Alexandria (Egypt) University, said in an interview.

Similarly, when a formerly euthyroid patient presents to an endocrinologist with sudden-onset hyperthyroidism, “Have you had a PCI recently?” should be one of the first questions asked. If the answer is yes, then further testing and imaging should be delayed at least 3 months, he noted.

Dr. Assaad and his associates examined 113 clinically euthyroid patients both before and several months after they underwent PCI for management of stable coronary artery disease. The cohort included 93 men, and patients’ ages ranged from 32 years to 73 years.

All the patients underwent a series of tests immediately before PCI, 24 hours after, and 3 months later. Those tests included serum free triiodothyronine (FT₃), free thyroxine (FT₄), thyroid-stimulating hormone (TSH), free T₃/T4 ratio, antithyroperoxidase (anti-TPO), and high-sensitivity C-reactive protein.

The gland’s morphology, including volume, vascularity, nodules, and echogenicity, were assessed on the same timetable using ultrasonography.

One day after PCI, there was a significant increase in serum FT₃ (5.2-0.5 vs. 3.3-0.7 pg/mL, P less than .001), and serum FT₄ (1.3 – 0.5 vs 1.2 – 0.3 ng/dL, P = .04), with no significant change in serum TSH.

Three months after PCI, there was a further significant increase in serum FT₄ (1.5 – 0.3 ng/dL), decrease in serum FT₃ returning to baseline (3.2 – 1.3 pg/mL), and a significant increase in serum TSH, compared with just before PCI (mean, 3.2-5 vs. 1.5-2.1 mIU/L, P less than .001). Serum anti-TPO (AU/mL) showed a significant increase 3 months after PCI.

There was a significant increase in thyroid gland volume 3 months after PCI (13.6-3.9 vs. 13.1-3.5 cm³, P = .02). The measured echogenicity of the thyroid gland showed a significant decrease 3 months after PCI (67.1-10.9 vs. 88.7-25.6 GWE, P less than .001).

Thyroid radiation had a negative effect on serum TSH, anti-TPO, FT₃, and FT₃/FT4 ratio, and an inverse correlation of dye injection time with serum anti-TPO and TSH, judging from the findings of a regression analysis model.

Dr. Assaad was not included on the list of presenters with relevant financial disclosures that was provided by the American Thyroid Association.

DENVER – Patients put on lenvatinib for the management of radioactive iodine–resistant differentiated thyroid cancer need to be taught how to monitor their blood pressure, be given a cuff with which to do so, and be called daily by someone on the medical staff for at least the first 2 weeks, according to Sina A. Jasim, MD, reporting on real world use of the drug since its approval in February 2015.

For now, oncologists prescribe and manage this drug. But as lenvatinib (Lenvima, Eisai) becomes more widely used, endocrinologists can expect to be the ones prescribing it sometimes and counseling patients in the practical aspects of using this drug, Dr. Jasim of the Mayo Clinic, Rochester, Minn., said in an interview.

It was with endocrinologists in mind that Dr. Jasim and her associates compiled postapproval data on adverse events and patient quality of life. To date, no such data – including those from Mayo – have been published, she said during her presentation at the American Thyroid Association’s annual meeting.

While lenvatinib seems to be a promising therapeutic agent, adverse events are common with its use and occur early. Patients treated with it at Mayo get called by someone on the medical staff daily for the first 2 weeks of therapy, are given a blood pressure cuff, and are taught how to use it. They also receive the cell phone number of a member of the medical staff to consult with about sudden symptoms.

This retrospective analysis involved 25 sequentially treated patients given lenvatinib for RAI-resistant differentiated thyroid cancer (14 papillary, 7 poorly differentiated, 3 Hürthle cell, and 1 follicular). While all had received RAI, 11 also had received radiotherapy, 8 had been given at least one other kinase inhibitor previously, and 3 had received two. Fourteen were on an antihypertensive medication at baseline.

All patients initiated lenvatinib at the full dose, but it was reduced in four patients because of old age, renal impairment, or prior colitis. Twenty-one patients developed adverse events within the first month of being on the drug. Hypertension occurred in 16. Six of these required either a raising of the dose of antihypertensive drug they were on at baseline or initiation of antihypertensive therapy.

Adverse events were pronounced enough that the lenvatinib dose had to be lowered in 11 within a median 33 days of starting the drug. Drug treatment had to be interrupted for at least 3 weeks in four patients (two cases of cholecystitis, one case of diverticulitis, and one case of skin lesions).

Patients reported that their quality of life was stable at 2 months, but that their fatigue was worse.

The mean duration of lenvatinib therapy was 6.5 months. Twenty patients are alive at the time of this report.

The study was sponsored by the Mayo Clinic. Dr. Jasim reported that she had no relevant financial disclosures.

But as lenvatinib (Lenvima, Eisai) becomes more widely used, endocrinologists can expect to be the ones prescribing it sometimes and counseling patients in the practical aspects of using this drug, Dr. Jasim of the Mayo Clinic, Rochester, Minn., said in an interview.

It was with endocrinologists in mind that Dr. Jasim and her associates compiled postapproval data on adverse events and patient quality of life. To date, no such data – including those from Mayo – have been published, she said during her presentation at the American Thyroid Association’s annual meeting.

While lenvatinib seems to be a promising therapeutic agent, adverse events are common with its use and occur early. Patients treated with it at Mayo get called by someone on the medical staff daily for the first 2 weeks of therapy, are given a blood pressure cuff, and are taught how to use it. They also receive the cell phone number of a member of the medical staff to consult with about sudden symptoms.

This retrospective analysis involved 25 sequentially treated patients given lenvatinib for RAI-resistant differentiated thyroid cancer (14 papillary, 7 poorly differentiated, 3 Hürthle cell, and 1 follicular). While all had received RAI, 11 also had received radiotherapy, 8 had been given at least one other kinase inhibitor previously, and 3 had received two. Fourteen were on an antihypertensive medication at baseline.

All patients initiated lenvatinib at the full dose, but it was reduced in four patients because of old age, renal impairment, or prior colitis. Twenty-one patients developed adverse events within the first month of being on the drug. Hypertension occurred in 16. Six of these required either a raising of the dose of antihypertensive drug they were on at baseline or initiation of antihypertensive therapy.

Adverse events were pronounced enough that the lenvatinib dose had to be lowered in 11 within a median 33 days of starting the drug. Drug treatment had to be interrupted for at least 3 weeks in four patients (two cases of cholecystitis, one case of diverticulitis, and one case of skin lesions).

Patients reported that their quality of life was stable at 2 months, but that their fatigue was worse.

The mean duration of lenvatinib therapy was 6.5 months. Twenty patients are alive at the time of this report.

The study was sponsored by the Mayo Clinic. Dr. Jasim reported that she had no relevant financial disclosures.
