Thyroid Cancer, Thyroid Nodule
Conditions
Brief summary
The purpose of this study is to evaluate the accuracy of Thyroscan in the differential diagnosis of benign and malignant thyroid nodules with suspecious ultrasound features
Detailed description
The prevalence of thyroid nodules by high-resolution ultrasound can be as high as 20%, though most of them are benign lesions, only about 5%-15% are malignant lesions. Based on 1.4 billion population in China, there are approximately 280 million thyroid nodule carriers, of which approximately 14-42 million are potential patients with thyroid cancer. Now thyroid cancer is the fastest growing cancer and the 4th most common cancer in women in China. Therefore, the key point in the evaluation of thyroid nodules is the differential diagnosis of benign and malignant nodules. At present, the commonly used imaging and cytological diagnostic techniques for thyroid nodules include ultrasound and ultrasound-guided fine needle aspiration biopsy (FNAB), as well as emerging molecular diagnostic techniques. The purpose of this study is to evaluate the accuracy of Thyroscan in the diagnosis of benign and malignant thyroid nodules with suspecious ultrasound features. For patients who have signed an informed consent, the subjects undergo fine needle aspiration of thyroid nodules classified as C-TIRADS catagories 3 or 4 under the guidance of ultrasound or palpation before receiving surgical treatment. One needle is used to prepare cytological smear, and one needle is preserved and sent to Thyroscan detection.

Inclusion criteria
1. Patients sign the informed consent form for participating in the reasearch study. 2. Patient's age is 18 years or older. 3. Ultrasound showed at least one thyroid nodule, and it was classified as C-TIRADS Category 3/4. 4. The surgeon has confirmed surgical indication and the subject is willing to undergo the planned surgical intervention at the participating medical institution; or cytology results are benign, and the nodule(s) have remained clinically stable-defined as absence of new high-risk ultrasound features and no significant change in size on serial imaging. 5. Surgical indications include but are not limited to one of the following conditions: 1) Thyroid nodules are compressed or affect aesthetics; 2) The patient's subjective wishes require surgical removal of the nodules; 3) FNA samples with indeterminate cytology are classified as Bethesda III and IV, requiring diagnostic surgery; 4) After the investigator's assessment, there are other surgical indications. 6. Preoperative FNAB to obtain sufficient cells.
Exclusion criteria
1. The subject has a history of thyroid tumor. 2. The subject is not suitable for fine-needle aspiration biopsy and surgical treatment due to other conditions such as comorbid diseases. 3. Subjects who intend to receive the radiofrequency ablation therapy. 4. Other conditions determined by the researcher that do not meet the criteria of enrollment.
