Management of endocrine surgical disorders during COVID-19 pandemic: expert opinion for non-surgical options.

PURPOSE: The COVID-19 pandemic brought unprecedented conditions for overall health care systems by restricting resources for non-COVID-19 patients. As the burden of the disease escalates, routine elective surgeries are being cancelled. The aim of this paper was to provide a guideline for management of endocrine surgical disorders during a pandemic. METHODS: We used Delphi method with a nine-scale Likert scale on two rounds of voting involving 64 experienced eminent surgeons and endocrinologists who had the necessary experience to provide insight on endocrine disorder management. All voting was done by email using a standard questionnaire. RESULTS: Overall, 37 recommendations were voted on. In two rounds, all recommendations reached an agreement and were either endorsed or rejected. Endorsed statements include dietary change in primary hyperparathyroidism, Cinacalcet treatment in secondary hyperparathyroidism, alpha-blocker administration for pheochromocytoma, methimazole ± ß-blocker combination for Graves' disease, and follow-up for fine-needle aspiration results of thyroid nodules indicated as Bethesda 3-4 cytological results and papillary microcarcinoma. CONCLUSION: This survey summarizes expert opinion for the management of endocrine surgical conditions during unprecedented times when access to surgical treatment is severely disrupted. The statements are not applicable in circumstances in which surgical treatment is possible.

Medullary thyroid microcarcinoma recommendations for treatment - a single-center experience.

BACKGROUND: Conflicting recommendations exist regarding lymph node (LN) surgery in microMTC (or=10pg/ml) and pentagastrin-stimulated calcitonin levels (sCT:>100pg/ml) were selected for initial surgery. None of the patient was a member of any known MTC family. Biochemical and morphological data of microMTC were compared with 146 patients with C-cell hyperplasia (CCH). RESULTS: MicroMTC (tumor diameter: 4.2+/-2.6mm; unifocal:68; multifocal:29) was documented in 97 of 159 (61%) MTC patients. In 11 (11%) patients, 1-19 LNs were involved. Correlating bCT and sCT levels neither predicted N-stage, nor differentiated between microMTC and CCH. CONCLUSIONS: The biochemical discrimination cannot be made between patients with CCH and MTC, and patients with MTC with/without LN metastasis. Thus, thyroidectomy and central neck dissection is indicated in patients with "mildly" elevated sCT levels (<560pg/ml) (LN positive: 1 of 37 patients [2.7%]). A lateral neck dissection may be added "on demand" (in the setting of measurable postoperative bCT and/or sCT levels indicating LN metastasis). Patients with "highly" elevated sCT (>or=560pg/ml) must be treated as "palpable" MTC (LN positive: 10 of 54 patients [18.5%]).
