Thyroid nodule is a mass of one or more abnormal tissue structures caused by various causes. Palpation of the general population prevalence
Thyroid nodule is a mass of one or more abnormal tissue structures caused by various causes. Palpation of the general population prevalence rate of thyroid nodules was 3-7%, high resolution ultrasound examination for the prevalence of thyroid nodules was 20-76%, thyroid nodules and thyroid cancer in recent years China's prevalence showed increasing trend, the majority of people through the examination found.
For the diagnosis of thyroid nodules procedures, let us listen to the director Liu Haixia how to say:
Audio: sweep the two-dimensional code to play a sound in the mobile phone
In fact, we found that thyroid nodules are most concerned about the problem is only one: nodules are benign or malignant. That being the case, how can we find the problem as soon as possible?
In August 2012, the Chinese Medical Association of Endocrinology and general surgery branch, head and neck surgery branch, nuclear medicine branch of a society jointly issued China's first "thyroid nodules and differentiated thyroid cancer diagnosis and treatment guidelines", let us see what authority.
The recommended evaluation of 1-1 thyroid nodules is benign and malignant; (recommended level A)
Serum levels of TSH should be detected in all thyroid nodules of 1-2 (A)
All 1-5 patients with thyroid nodules should be treated with neck ultrasonography (A)
It is suggested that FNAB is the most sensitive and specific method for 1-9 in the preoperative evaluation of benign and malignant thyroid nodules (A)
What is the recommended level A in parentheses, look at the following figure to understand it.
The above mentioned FNAB is actually a fine needle cytology of thyroid gland.
From the table we can see that the results of FNAB is malignant, the possibility of malignant nodules as high as 97-99%.
In view of this examination usually visits often ask questions answered as follows:
(1) what is the accuracy of fine needle cytology?
The accuracy can reach more than 90%; if the guide said, this is the evaluation of benign and malignant thyroid nodules with the highest accuracy method before the operation, that is to say, in order to avoid the benign nodules do unnecessary surgery, surgery should be done before the examination to evaluate the benign and malignant nodules.
Explanation: not all benign nodules are not surgery, even the surgical treatment of benign nodules should be: nodules with dyspnea, dysphagia and oppression; hyperthyroidism and medical drugs can not be controlled; nodules in the chest or mediastinal; considering the existence of canceration factors.
(2) why do thyroid fine needle cytology?
In addition to helping to determine the benign and malignant nodules, preoperative evaluation, the examination for other unknown causes of thyroid disease can be diagnosed at the level of cytology, clear etiology.
(3) which nodules should be examined by thyroid cytology?
Nodules with a diameter greater than 1 cm should be routinely examined;
Less than 1 cm in diameter of the nodules do not need routine this check; however, if less than 1 cm in diameter, with some special features such as: ultrasound unclear, irregular shape, calcification, blood disorders, family relatives had thyroid cancer, and so on are recommended for inspection;
In addition, if the ultrasound showed a high degree of suspicion of malignancy, thyroid fine needle cytology could not be used as a routine examination.
In response to the eighth session of the international Thyroid Awareness Week "activities, 2 families in the Second Affiliated Hospital of Dalian Medical University endocrine activities during the exemption from registration fee in patients with hyperthyroidism exophthalmos, thyrotoxic exophthalmos patients only need to receive a free number in the Second Affiliated Hospital of Dalian Medical University 2 Department of endocrine expert team any visits of experts, can be face to face with endocrine experts accept, the most professional and standardized diagnosis and treatment. The event will end on the end of the month (2016.5.31), although the activity is coming to an end, but we focus on thyroid health enthusiasm never reduced, the staff of 2, Second Affiliated Hospital of Dalian Medical University endocrine will continue to work with you a health watch!
