A recent study proposed new TNM groupings for better survival discrimination among stage groups for medullary thyroid carcinoma (MTC) and validated these groupings in a population-based cohort in the United States. However, it is unknown how well the groupings perform in populations outside the United States. Consequently, we conducted the first population-based study aiming to evaluate if the recently proposed TNM groupings provide better survival discrimination than the current American Joint Committee on Cancer (AJCC) TNM staging system (seventh and eighth edition) in a nationwide MTC cohort outside the United States. This retrospective cohort study included 191 patients identified from the nationwide Danish MTC cohort between 1997 and 2014. In multivariate analysis, hazard ratios for overall survival under the current AJCC TNM staging system vs the proposed TNM groupings with stage I as reference were 1.32 (95% CI: 0.38–4.57) vs 3.04 (95% CI: 1.38–6.67) for stage II, 2.06 (95% CI: 0.45–9.39) vs 3.59 (95% CI: 1.61–8.03) for stage III and 5.87 (95% CI: 2.02–17.01) vs 59.26 (20.53–171.02) for stage IV. The newly proposed TNM groupings appear to provide better survival discrimination in the nationwide Danish MTC cohort than the current AJCC TNM staging. Adaption of the proposed TNM groupings by the current AJCC TNM staging system may potentially improve accurateness in survival discrimination. However, before such an adaption further population-based studies securing external validity are needed.

Serum calcitonin screening has recently been found to be a useful supplement to fine-needle aspiration biopsy, ultrasound and radionuclide imaging in the evaluation of thyroid nodules. We describe a case where introduction of routine calcitonin screening in nodular thyroid disease led to the detection of a family with medullary thyroid carcinoma. The benefits and problems of basal and stimulated serum calcitonin testing and ret-proto-oncogene mutation studies are exemplified and we discuss the appropriate use and interpretation of these tests. We conclude that routine basal serum calcitonin measurement in nodular thyroid disease and thoughtful use of ret-mutation analysis is cost-effective in detecting medullary thyroid carcinoma and multiple endocrine neoplasia type II.

OBJECTIVE: To evaluate the usefulness of preoperative serum calcitonin (sCT) in patients with nodular disease without suspicion of medullary thyroid carcinoma (MTC) in history or cytology. PATIENTS AND METHODS: sCT was measured before thyroidectomy in 494 patients with nodular disease who had no family history of MTC or multiple endocrine neoplasia type 2, and no cytological suspicion of MTC. RESULTS: Basal sCT was < 10 ng/mL in 482 patients and none of them had MTC. One patient with basal sCT > 100 pg/mL had MTC. Among the 11 patients with basal sCT between 10 and 100 pg/mL, MTC was diagnosed in only one. The two patients with MTC were submitted to total thyroidectomy, combined with elective lymph node dissection indicated exclusively based on hypercalcitoninemia, and sCT was undetectable after six months. CONCLUSIONS: Preoperative sCT is useful for the detection of sporadic MTC in patients with nodular disease, even in the absence of suspicious history or cytology.
