How does a strong family history of breast cancer influence your decision between RAI and thyroidectomy for definitive treatment of hyperthyroidism, in light of emerging observational data suggesting a possible association between RAI and increased breast cancer risk?
There is an increased risk for solid tumors, especially breast cancer, following radioactive iodine (relative risk from 0.45-2.55). This data is strongest for those treated for thyroid cancer as opposed to Graves disease, as it is dose dependent, but studies do support an increased risk for breast c...
Does the degree of TSH suppression significantly impact the risk of differentiated thyroid carcinoma recurrence?
This is a very timely question. The new 2025 Guidelines for thyroid cancer was just published. They cite studies that recurrence and cancer dead for low and low/ intermediate risk thyroid cancer patients are not affected by TSH suppression. The recommended TSH is normal and less than 4 uU/ml. It is ...
Can carbamazepine make thyroid function test results look spuriously abnormal?
Carbamazepine can also displace thyroid hormone from binding proteins. Although in the short term this might transiently increase free T4 (with a reciprocal decrease in TSH), thyroid function tests should normalize once an equilibrium is achieved. In some assays that rely on dilution of the sample, ...
Would you recommend RAI ablation therapy to patients with PTC who are s/p hemi-thyroidectomy and decline completion thyroidectomy despite meeting criteria based on pathology results?
RAI therapy will work to ablate the remaining thyroid lobe with about a 69% success rate using a high dose of I-131. However, extra-thyroidal tumor cells will likely not pick up I-131 with this treatment. A good reference is the 2020 meta-analysis in the Journal of Nuclear Medicine: Piccardo et al.,...
If a patient requires more than 5 mg per day of methimazole long term do you recommend alternative treatment options such as radio-iodine ablation or surgery?
Long term use of methimazole is generally safe as long as no history of LFT elevation or abnormally low white blood cell counts. Typically, toxic multinodular goiters respond well to low dose methimazole and patients can be managed in this fashion long-term without any issues. Graves patients may re...
What is the evidence, if any, for the use of low dose naltrexone in the treatment of autoimmune thyroiditis?
I do not prescribe naltrexone for thyroid disease because I have not found data to support its use. In theory, low dose naltrexone (LDN) could decrease inflammation and thus potentially block development of overt hypothyroidism in TPO positive patients. But, at this time, it is anecdotal, with no ha...
Which antidiabetic agents would you recommend to treat hyperglycemia secondary to PI3K and AKT inhibitor therapy?
In the patients I have seen with this condition, typically insulin is what works best.
Prior to gender affirming surgery, do you hold estrogen (or convert to transdermal) to minimize postoperative VTE risk?
I'd divide this into 2 sub-questions: what to do in a patient who has a history of thrombosis, and what to do in a patient without a history of thrombosis. In a patient with prior thrombosis, I would generally have them on indefinite anticoagulation alongside ongoing estrogen use. We know that trans...
Would you consider a shorter course of Romosozumab (3 months) followed by maintenance therapy given recent evidence that it is noninferior to 12 months of therapy for treatment of severe osteoporosis?
A recent publication led by Leder et al (Lancet Diabetes Endocrinol 2026;14: 216–22) demonstrated that a brief 3-month course of romosozumab followed by denosumab was noninferior to a full 12-month course of romosozumab given in the standard manner. This is consistent with earlier (nonrandomized) ob...
Would you ever recommend radiofrequency ablation over surgery or radioiodine for a patient with an autonomously functioning thyroid nodule?
This answer can be very patient-specific, of course, in terms of preference, co-morbidities (is surgery safe), and risk of the nodule and size. I don't often do RAI for toxic adenoma /toxic MNG if the patient is a good surgical candidate or tolerates anti-thyroidals well without incident. I also hav...
