Abstract
INTRODUCTION Medullary thyroid carcinoma (MTC) is a rare neuroendocrine tumor from parafollicular cells that produce calcitonin (Ct). Despite several existing guidelines for the surgical management of sporadic MTC (sMTC), optimal initial surgical management of the thyroid, the central and the lateral neck remains a matter of debate. METHODS A systematic review in PubMed and Scopus for current guidelines addressing the surgical management of sMTC and its referenced citations was conducted as per the PRISMA guidelines. RESULTS Two-hundred and one articles were identified, of which 7 met the inclusion criteria. Overall, guidelines vary significantly in their recommendations for the surgical management of sMTC. Only one guideline recommended partial thyroidectomy for limited disease, but the possibility to avoid completion thyroidectomy in selected cases is acknowledged in 42% (3/7) of the remaining guidelines. The majority of guidelines (71.4%; 5/7) recommended prophylactic central neck dissection (CND) for all patients while the remaining two guidelines recommended CND based on Ct level and tumor size. The role of prophylactic lateral neck dissection based on preoperative Ct levels was recommended by 42% (3/7) of guidelines. Overall, these guidelines are based on low-quality evidence, mostly single-center retrospective series, some of which are over 20 years old. CONCLUSION Current surgical management guidelines of sMTC should be revised, and ought to be based on updated data challenging current recommendations, which are based on historic, low-quality evidence. Partial thyroidectomy may become a viable option for small, limited tumors. Prospective, multi-center studies may be useful to conclude whether prophylactic ND is necessary in all sMTC patients.

Extent of Surgery for Medullary Thyroid Cancer and Prevalence of Occult Contralateral Foci. JAMA Otolaryngol Head Neck Surg 2024; 150:209-214. [PMID: 38270925 PMCID: PMC10811588 DOI: 10.1001/jamaoto.2023.4376] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 11/21/2023] [Indexed: 01/26/2024]
Abstract
Importance Standard treatment for patients with medullary thyroid cancer (MTC) consists of total thyroidectomy with central neck dissection, but the rationale for bilateral surgery in patients with unilateral disease on ultrasonography remains unclear. Objective To determine the presence of occult contralateral disease (lesions not seen on preoperative ultrasonography) in patients with MTC as a rationale for total thyroidectomy. Design, Setting, and Participants This multi-institutional, retrospective cohort study was conducted from September 1998 to April 2022 in academic medical centers and included patients with MTC who underwent thyroidectomy with preoperative imaging. Main Outcomes and Measures The primary end point was the prevalence of sonographically occult foci of MTC in the contralateral lobe among patients with sporadic MTC. Results The cohort comprised 176 patients with a median age at diagnosis of 55 years (range, 2-87 years), 69 (57.6%) of whom were female. Genetic testing was performed in 109 patients (61.9%), 48 (27.5%) of whom carried germline RET variants. Initial surgical management consisted of total thyroidectomy (161 [91.0%]), lobectomy followed by completion thyroidectomy (7 [4.0%]), and lobectomy alone (8 [4.5%]). Central and lateral neck dissections were performed as part of initial therapy for 146 patients (83.1%). In the entire cohort of 176 patients, 46 (26.0%) had contralateral foci disease and 9 (5.1%) had occult contralateral foci that were not identified on preoperative ultrasonography. Among 109 patients who underwent genetic testing, 38 (34.9%) had contralateral disease, 8 (7.3%) of whom had occult contralateral disease not seen on preoperative ultrasonography. Patients with sporadic MTC experienced a 95.7% reduction in the odds of having a focus of MTC in the contralateral lobe compared with patients with a germline RET variant (odds ratio, 0.043; 95% CI, 0.013-0.123). When adjusting for age, sex, tumor size, and lymph node involvement, the odds ratio of having contralateral MTC in patients with sporadic disease was 0.034 (95% CI, 0.007-0.116). Among patients who underwent lobectomy alone with postoperative calcitonin levels, 5 of 12 (41.7%) achieved undetectable calcitonin levels (<2.0 pg/mL; to convert to pmol/L, multiply by 0.292). Conclusions and Relevance The results of this cohort study suggest that a staged approach involving initial thyroid lobectomy could be considered in patients with sporadic MTC and no contralateral ultrasonography findings, with no further surgery if calcitonin levels became undetectable. Further work using prospective randomized clinical trials to evaluate lobectomy as a biochemical cure in patients presenting with unilateral disease is warranted.

Sex differences and racial/ethnic disparities in the presentation and treatment of medullary thyroid cancer. Am J Surg 2024:S0002-9610(24)00070-9.

Abstract
BACKGROUND This study assessed for disparities in the presentation and management of medullary thyroid cancer (MTC). METHODS Patients with MTC (2010-2020) were identified from the National Cancer Database. Differences in disease presentation and likelihood of guideline-concordant surgical management (total thyroidectomy and resection of ≥1 lymph node) were assessed by sex and race/ethnicity. RESULTS Of 6154 patients, 68.2% underwent guideline-concordant surgery. Tumors >4 cm were more likely in men (vs. women: OR 2.47, p < 0.001) and Hispanic patients (vs. White patients: OR 1.52, p = 0.001). Non-White patients were more likely to have distant metastases (Black: OR 1.63, p = 0.002; Hispanic: OR 1.44, p = 0.038) and experienced longer time to surgery (Black: HR 0.66, p < 0.001; Hispanic: HR 0.71, p < 0.001). Black patients were less likely to undergo guideline-concordant surgery (OR 0.70, p = 0.022). CONCLUSIONS Male and non-White patients with MTC more frequently present with advanced disease, and Black patients are less likely to undergo guideline-concordant surgery.
