‘Calcitonin screening’ is not accepted as the standard of care in daily practice. The clinical and surgical consequences of ‘calcitonin screening’ in a series of patients with mildly elevated basal calcitonin and pentagastrin stimulated calcitonin levels are presented. 260 patients with elevated basal (>10 pg/ml) and stimulated calcitonin levels (>100 pg/ml) were enrolled in this prospective study. None of the patients was member of a known medullary thyroid carcinoma family. Thyroidectomy and bilateral central and lateral neck dissections were performed. Testing for the presence of germ-line mutations was performed in all patients. Histological and immunohistochemical findings were compared with basal and stimulated calcitonin levels. All patients were subsequently followed biochemically. C-cell hyperplasia (CCH) was found in 126 (49%) and medullary thyroid cancer was found in 134 (51%) patients. RET proto-oncogen mutations were documented in 22 (8%) patients (medullary thyroid cancer:18, CCH:4). In 56 (46%) of 122 patients, sporadic CCH was classified neoplastic (‘carcinoma in situ’). Of 97 (72%; 10 with hereditary medullary thyroid cancer) had pT1 (International Union against Cancer recommendations 2002) and 33 (25%) had pT2 or pT3 and 4 (3%) pT4 tumors. Of 39 (29.1%) had lymph node metastases. 106 (79.1%; 15 (38.5%) with lymph node metastases) patients were cured. Evaluation of basal and stimulated calcitonin levels enables the prediction of medullary thyroid cancer. All patients with basal calcitonin >64 pg/ml and stimulated calcitonin >560 pg/ml have medullary thyroid cancer. Medullary thyroid cancer was documented in 20% of patients with basal calcitonin >10 pg/ml but <64 pg/ml and stimulated calcitonin >100 pg/ml but <560 pg/ml.

In last ten years, significant advances have occurred in thyroid endocrinology, as a consequence of the generalized use of molecular biology techniques. New genes involved in the development of thyroid cancer have been identified, which had a great impact on our understanding of thyroid cancer predisposition. All cancers are genetic in origin because they arise from mutations in a single somatic cell, but the genetic changes in sporadic cancers are confined to a particular tissue. In inherited cancers, a predisposing mutation is present in all somatic cells and in the germ line, which enables the transmission of risk to the next generation. Cancer genetics offers a model of how information on the genetics of inherited cancers could affect identification of individuals at increased genetic risk.

The monoclonal anti-CEA F(ab’)2 fragment MAb BW 431/31, labelled with 123I or111 In, was used for immunoscintigraphy (IS) in 9 patients with medullary cancer of the thyroid (CCC). The results of 11 studies lead to the following conclusions: 1) When using radioiodine as a label for MAb in IS, potassium iodide is absolutely necessary to block the thyroid which is of special importance in patients with thyroid cancer; 2) Preinjection of “cold” MAb reduces the relatively high unspecific uptake (especially in bone marrow) of MAb BW 431/31, which is of special importance for the antibody labelled with 111 In; 3) IS with MAb BW 413/31 in patients with CCC and elevated serum CEA is positive only in cases with large secondaries; and 4) In patients with CCC and several manifestations of secondaries, only a single (large) metastasis may be apparent.
