13 марта 2020г ВОЗ объявила пандемию SARS-Cov-2 (COVID-19) , и быстрое увеличение числа заболевших и умерших разрушил привычный уклад медицинской помощи во многих странах. Чтобы уменьшить вероятнoсть заражения COVID-19 и в связи в ограниченностью медицинских ресурсов медицины U.S. Center for Disease Control and Prevention (CDC), в сотрудничестве с U.S. Surgeon General, опубликовали национальные клинические рекомендации по прекращению ряда не ургентных процедур. Fine needle aspiration (FNA) of thyroid nodules is a standard bread and butter procedure for endocrinologists. Не будем переводить, ладно ??? не так поймут ГА) Как же быть с ТАБ ? Прекратить их или продолжать ? По этому поводу Endocrinology Division at Phoenix VA Healthcare System (PVAHCS) недавно провела мультидисциплинарное совещание, резюме которого мы здесь предоставляем .
Все элективные ( факультативные) хирургические процедура по определению не являются ургентыми , и планируются заблаговременно.некоторые из них абсолютно необходимы и потенциально позволят продлить качественную жизнь ,и ТАБ входит в эту категорию Большинство бессимптомных узлов обнаружены случайно, либо при пальпации, либо при различных имиджевых методах, и 90% из них доброкачественны, а среди злокачественных 90% -высокодифференцированные раки, имеющие прекрасный прогноз. Практически нет доказательств, что ранее выявление этих раков принципиально изменит судьбу больного . тем более, что общая летальность для ВДРЩ остается менее ~0.5%,хотя постоянно растет число различных имиджевых исследований области шеи
Таким образом, наша группа рекомендует при асимптоматических узлах, с учетом УЗИ характеристик и клинические проявления переносить ТАБ
There is little evidence that early detection and treatment of DTC significantly alters disease outcomes, as the overall mortality rate for DTC has remained low at ~0.5%, despite a steady rise in its incidence as neck imaging has become more widespread (2). Our group therefore recommends that FNA biopsy of most asymptomatic thyroid nodules, taking into account the sonographic characteristics and patients’ clinical picture, be deferred to a later time, when risk of exposure to COVID-19 is more manageable and resource restriction is no longer a concern. These patients should be interviewed by an endocrinologist (preferably via telehealth) to collect their clinical history and assess the patients’ perception of the disease and risk of malignancy. If education and reassurance fail to relieve the patient’s anxiety over the risk of cancer and the timeline regarding clinical management, it is reasonable to offer the patient a consultation with a surgeon who manages thyroid disease for a second opinion. Of note, we believe that the ultrasound features of thyroid nodules should not be the sole basis for pursuing immediate thyroid FNA Clin Thyroidol 2020;32:156–158. Downloaded by from
American Thyroid Association or surgery, but can guide the priority for the future timing of an FNA procedure. Regarding medullary thyroid cancer (MTC), early diagnosis and surgery do significantly improve outcomes (3). Therefore, delaying FNA of nodules harboring MTC could be potentially injurious. Although universal serum calcitonin measurements for patient with thyroid nodules is still controversial in the U.S., we feel that it is justified to assess calcitonin levels in patients with thyroid nodules that would usually be indicated for FNA, especially those with family history of MTC, or nodules located in the usual locations of MTC (i.e. posterior upper third of lateral lobes), during this pandemic. If calcitonin levels are >10 pg/ml, FNA should be offered as early as possible. Significantly elevated serum calcitonin levels (e.g. > 100 pg/ml) should be considered an indication for surgery without cytologic confirmation by FNA. Anaplastic thyroid cancer (ATC) is one of the few occasions when thyroid surgery should be performed on an urgent basis, as this condition can worsen very rapidly. Patients typically present with a rapidly enlarging thyroid mass that is associated with compressive symptoms, such as dysphagia and dyspnea. FNA usually is part of the pre-operative workup, but often is non-diagnostic and may require additional sampling as core or open biopsies. At the time of this pandemic, it is reasonable that after a multidisciplinary discussion, such patients with the appropriate clinical scenario be referred for thyroid surgery, with or without prior FNA, based on the team’s judgement. There are also longstanding thyroid masses that occasionally cause compressive symptoms. They are usually large and/or closely associated with vital structures such as the trachea and esophagus. Thyroid surgery (lobectomy or total thyroidectomy) is typically warranted, with prior FNA helpful to obtain a cytologic diagnosis, as this may change the extent of surgery. However, the value of FNA in these situations is less compelling in the current COVID-19 setting, as the basis of decision for surgery has been already determined. (It is noted that a confirmed cancer diagnosis may alter these treatment decisions by prompting more extensive surgery, such as recommendations to pursue total thyroidectomy and/or central neck dissection). Nevertheless, during the pandemic, we believe that the vast majority of thyroid FNAs should be considered optional, and extent of surgery can be determined by pathological analysis of frozen sections intraoperatively. Individual treatment decisions would need to be made if it is a suspicious cervical lymph node that is being proposed for FNA. Broadly, symptomatic patients with compressive symptoms threatening vital structures can be directly referred to a surgeon, with the timing for surgery jointly decided based on the severity of symptoms, rapidity of disease progression, local COVID-19 status, and available resources. As some of symptoms such as dysphagia are nonspecific, further studies such as a swallow study, esophagogastroduodenoscopy (EGD), and other imaging tests may be required prior to such referrals. When the need for an urgent thyroid FNA arises, safety for both the patients and the operators need to be addressed. We believe that such patients should be tested for COVID-19 by screening for symptoms and undergoing the available nucleic acid test. The operator should wear personal protective equipment (PPE) for the protection of both the patient and self. As any clinician managing thyroid nodules and thyroid cancers would attest, it is impossible to anticipate every clinical scenario, but we hope the above discussion will provide a framework for GUEST EDITORIAL Considerations for Thyroid Ming Li, Ricardo C.
