Parathyroid cancer (PC) is extremely rare, usually diagnosed after surgery, there are no clinical recommendations for the treatment of metastatic PC.</p><p><bold>The study objective</bold> is to present the results of a clinical examination and treatment of patients with PC.</p><p><bold>Materials and methods</bold>. Retrospective analysis of 15 PC patients treated from 2001 to 2019. The results of laboratory tests, the surgical approach, the results of treatment, the rate of metastasis and relapse within 19 months (3 months – 11.6 years) after surgery are presented.</p><p><bold>Results</bold>. Tumor size is 35 mm (20–45 mm). Lymph node metastases – 1 (6.7 %), distant metastases – 2 (13 %). The median initial parathyroid hormone (PTH) is 735 pg/mL, calcium 3.22 mmol/L. Severe hyperparathyroidism with osteitis fibrosa cystica – in 6 (40 %). The surgical approach was parathyroidectomy in 10 (67 %), en bloc resection in 5 (33 %). Normalization of PTH and calcium after surgery – 13 (87 %). In two patients with distant metastases, the PTH and calcium remained high. A patient with Th6 vertebral metastasis was successfully operated on, with normalization of PTH and calcium, and 1.5 years was without relapse. A patient with lung and liver metastases received sorafenib after surgery, with decrease in calcium level. She died of progression 12 months after operation. Among patients with normalization of postoperative PTH, one had local relapse after 4 years. The patient was re-operated and 1 year after the second operation without relapse. The remaining patients are without relapse/progression.</p><p><bold>Conclusion</bold>. At the time of diagnosis, lymph node metastases are in 6.7 %, distant metastases – 13 %. Normalization of PTH and calcium after surgery suggests a good prognosis, but does not exclude the recurrence in the future, which requires long-term follow-up. Repeated surgery for local recurrence or solitary distant metastases can provide stable remission. Sorafenib in metastatic PC has managed to control hypercalcemia in the short term, however, antitumor efficacy requires further study.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Рак паращитовидной железы встречается крайне редко и диагностируется обычно после хирургического удаления опухоли, поэтому на данный момент клинические рекомендации по лечению его метастатических форм не разработаны.</p><p><bold>Цель исследования</bold> – проанализировать собственный опыт клинического обследования и лечения больных раком паращитовидной железы (РПЩЖ) и сопоставить результаты с данными научной литературы.</p><p><bold>Материалы и методы</bold>. Выполнен ретроспективный анализ сведений о 15 больных РПЩЖ, проходивших лечение с 2001 по 2019 г. Проанализированы результаты лабораторных исследований, объем операции, исходы лечения, частота метастазирования и рецидивов, зарегистрированных в течение периода послеоперационного наблюдения (медиана 19 мес (от 3 мес до 11,6 года)).</p><p><bold>Результаты</bold>. Медиана размера опухоли составила 35 мм (20–45 мм). Метастазы в регионарных лимфатических узлах выявлены у 1 (6,7 %), отдаленные метастазы – у 2 (13 %). Медиана уровня дооперационного паратиреоидного гормона (ПТГ) – 735 пг/мл, кальция 3,22 ммоль/л. Тяжелая костная форма гиперпаратиреоза с фиброзно-кистозным остеитом имела место у 6 (40 %) пациентов. Хирургическое лечение в объеме паратиреоидэктомии выполнено в 10 (67 %) случаях, расширенная резекция – в 5 (33 %). После операции уровень ПТГ и кальция нормализовался у 13 (87 %) больных, оставался высоким – у 2 пациентов с отдаленными метастазами. Пациент с метастазом в дужке позвонка Th6 был успешно оперирован, что привело к нормализации уровня ПТГ и кальция, за 1,5 года рецидивов у него не зарегистрировано. Пациентка с метастазами в легких и печени получала после операции сорафениб, на фоне которого снизился уровень кальция; в результате прогрессирования заболевания наступил летальный исход через 12 мес после операции. У 1 пациента с нормальным послеоперационным уровнем ПТГ возник местный рецидив через 4 года. Пациент повторно оперирован; в течение 1 года после операции рецидивов не наблюдается. У остальных больных признаки рецидива или прогрессирования отсутствуют.</p><p><bold>Заключение</bold>. На момент диагностики РПЩЖ регионарные метастазы имелись у 6,7 % пациентов, отдаленные метастазы – у 13 %. Нормализация уровня ПТГ и кальция после операции свидетельствует о хорошем прогнозе, однако не исключает вероятность рецидива, что требует длительного динамического наблюдения. Повторные операции при местном рецидиве и единичных отдаленных метастазах позволяют добиться стойкой ремиссии. При распространенном метастатическом РПЩЖ терапия сорафенибом позволила контролировать гиперкальциемию в течение короткого времени, однако эта противоопухолевая эффективность требует дальнейшего изучения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>parathyroid cancer</kwd><kwd>hyperparathyroidism</kwd><kwd>parathyroid hormone</kwd><kwd>hypercalcemia</kwd><kwd>case report</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак паращитовидной железы</kwd><kwd>гиперпаратиреоз</kwd><kwd>паратиреоидный гормон</kwd><kwd>гиперкальциемия</kwd><kwd>клинический случай</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
