Study Arms (2)
Percutaneous laser ablation(PLA)
EXPERIMENTALEligible participants with PTMC will be randomly assigned to this group and undergo percutaneous laser ablation(PLA). All the process is under the detection of real-time ultrasound.After surgery, all the patients will accept contrast-enhanced ultrasound(CEUS), regular ultrasound follow-up, thyroid functional detection, fine-needle aspiration biopsy(FNAB), neck CT.Per and post-operative complications, need of drug treatment, length of hospital admission and customer satisfaction will be registered.
Surgery
ACTIVE COMPARATOREligible participants with PTMC will be randomly assigned to this group and undergo total/subtotal thyroid surgery.
Interventions
During the PLA, the patient is in supine position with head extended: the physician, ultrasound assistant and trained nurse work within the sterile field. Under constant ultrasound image guidance and after local anesthesia by means of 2% xylocaine infiltration, thin needles (21G) are positioned in the thyroid lesion, within safety distance from the surrounding anatomical structures. A plane-cut tip fiber optics is inserted into the PTMC through the needle. The laser at 1064 nm wavelength is turned on for 10 minutes until the pre-established energy dose is attained. There is usually no pain or very limited pain.
Patients are routinely disinfected and spread the drapes after general anesthesia. Neck skin, fat, placenta muscle are incised successively. The flap is separated to the upper edge of thyroid cartilage, neck white line is incised and anterior muscle group is separated. Then both sides thyroid lobes are exposed. Cut off the isthmus, ligature the thyroid artery, cut off the upper pole. Ligature and cut off the ipsilateral thyroid vein. Reveal and protect the ipsilateral recurrent laryngeal nerve and the parathyroid gland during the entire process. Finally patient is performed total thyroidectomy or subtotal thyroidectomy.
Eligibility Criteria
You may qualify if:
- Newly diagnosed PTMC (maximun diameter\> = 5 mm and \< = 10 mm) proved by fine needle aspiration biopsy with good thyroid function;
- Age≥ 18 Y;
- Single nodule without thyroid capsule contact;
- There had more than 3mm distance between nodules and trachea, carotid artery, recurrent laryngeal nerve (The distance should up to 5mm after injection of isolation fluid);
- No coarse calcification or eggshell-like calcification;
- Imaging examination without local or distant metastasis;
- Without chemotherapy, radiotherapy and other related therapies;
- A complete clinical, pathological and follow-up information;
- Get informed consent signed by the patient or family member.
You may not qualify if:
- Multifocal PTMC;
- Combined with other types of thyroid cancer or hyperthyroidism;
- Lesion contact with thyroid capsule or located in the isthmus;
- Serious coagulation dysfunction;
- Contralateral vocal cord paralysis;
- Imaging examination with local or distant metastasis;
- Active Tuberculosis and HIV-positive patients;
- Patients can not understand or follow research protocol;
- Pregnant woman.
