Во всех этих документах среди многих рекомендаций есть и рекомендация по определению базального уровня кальцитонина всем пациентам с узловой патологией щитовидной железы. Однако данные рекомендации выполняются далеко не всегда, вероятно, по экономическим причинам. Так, в нашу клинику обратилась пациентка, которой по месту жительства было проведено хирургическое лечение по поводу папиллярного рака (фолликулярный вариант) щитовидной железы в объеме тиреоидэктомии с претрахеальной лимфодиссекцией и последующим курсом радиойодтерапии. На очередном контрольном обследовании по месту жительства был заподозрен рецидив заболевания, и пациентка была направлена в поликлинику НМИЦ онкологии им. Н.Н. Блохина для консультации. В нашей клинике были проведены диагностические исследования, включающие пересмотр готовых цитологических и гистологических препаратов, получено заключение: медуллярный рак щитовидной железы. Определение базального уровня кальцитонина в сыворотке крови показало значение 1292 пг/мл. После проведенного повторного хирургического лечения уровень базального кальцитонина значительно снизился.</p><p>Описанный нами случай показывает, что во избежание таких ошибок, которая описана в нашем клиническом случае, видится необходимость следовать национальным рекомендациям, международным стандартам и проводить определение уровня базального кальцитонина всем пациентам с узловой патологией щитовидной железы, обратившимся за консультацией и лечением в медицинские учреждения.</p></abstract><trans-abstract xml:lang="en"><p>There are International and Russian guidelines for the diagnosis and treatment of medullary thyroid carcinoma. There is a recommendation to determine the basal level of calcitonin for all patients with nodular thyroid disease at the all of these documents. However, this test is not performed for this category of patients routinely even in large clinics for a number of reasons, the main one, which seems to be an economic issue. Six months ago a patient addressed to our clinic who underwent surgical treatment for a papillary carcinoma (follicular variant) of the thyroid gland in the volume of thyroidectomy with pre-tracheal lymphodissection and subsequent course of radioiodine therapy at the place of residence. A relapse of the disease was suspected on the control examination at the place of residence and the patient was sent for consultation to the polyclinic of the N.N. Blokhin National Medical Research Center of Oncology. In our clinic, diagnostic studies were carried out, including a revision of the finished cytological and histological preparations and a conclusion was obtained – medullary carcinoma of the thyroid. Determination of basal level of calcitonin in serum showed a value of 1292 pg/ml. The level of basal calcitonin significantly decreased after repeated surgical treatment. This case shows that in order to avoid such mistake, which is described in our clinical case, it seems necessary to follow the national recommendations, international standards to determine the level of basal calcitonin for all patients with thyroid nodal pathology who consulted and treated in medical institutions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>клинический случай</kwd><kwd>медуллярный рак щитовидной железы</kwd><kwd>скрининг</kwd><kwd>кальцитонин</kwd><kwd>цитология</kwd><kwd>тонкоигольная аспирационная биопсия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>case report</kwd><kwd>medullary thyroid cancer</kwd><kwd>screening</kwd><kwd>calcitonin</kwd><kwd>cytology</kwd><kwd>fine-needle aspiration</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kloos RT, Eng C, Evans DB, et al.
