Brief Summary:
Investigators intend to evaluate the efficiency of Radiofrequency ablation (RFA) therapy to treat papillary thyroid carcinoma.

Condition or disease Intervention/treatment Phase
Papillary Thyroid Cancer Papillary Thyroid Microcarcinoma Device: RFA Not Applicable

Detailed Description:

Investigators plan to identify patients with small papillary thyroid carcinoma and subject such patients to radiofrequency ablation (RFA) therapy.

Following RFA procedure patients will be monitored to study the changes in primary tumor volume, development of lymph node involvement, development of distant metastasis and changes in serum thyroid hormone levels.

Investigators will also assess the stability of these changes (need for repeat therapy) and the safety of the RFA procedure.

Arm Intervention/treatment
Experimental: RFA Group Device: RFA
Radiofrequency ablation of selectively targeted thyroid nodule to treat papillary thyroid cancer.

Primary Outcome Measures :
  1. Changes in thyroid nodule size (overall volume measured in percentage) [ Time Frame: 18 months ]
    Thyroid tumor volume shrinkage in percentage will be assessed by ultrasound and compared with pre-procedure volume.

Secondary Outcome Measures :
  1. Pain related to RFA procedure [ Time Frame: 1-2 months ]
    McGill Pain Questionnaire (Pain intensity scale: 0 = none, 1 = mild, 2 = moderate or 3 = severe)

  2. Development of lymph node involvement [ Time Frame: 18 months ]
    Cervical adenopathy

  3. Development of distant metastasis [ Time Frame: 18 months ]
    Distant metastatic sites

  4. Safety of the RFA procedure [ Time Frame: 1-2 months ]
    Evaluation of site of RFA for local complication and asses pain with McGill Pain Questionnaire (Pain intensity scale: 0 = none, 1 = mild, 2 = moderate or 3 = severe)

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 85 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Are adults
  • Nodule with Papillary thyroid carcinoma meeting the below criteria:

    • Diagnosed by FNA cytology.
    • Size < 1.5 cm
    • Non-surgical therapy is considered acceptable by the treating physician
    • Radiology evaluation deems the lesion amenable to RFA therapy with minimal risk of complication

Exclusion Criteria:

  • Clinical evidence for local or distant metastatic disease
  • Pregnancy
  • Vocal cord paralysis on contralateral side
  • Coagulopathy or patients on anticoagulation therapy
  • Patients with prior neck surgery or neck radiation
  • Patients with neck anatomy that precludes easy access by RFA
  • Patients with comorbidities deemed too high of a risk for general anesthesia
  • Treatment with another investigational drug or intervention (within 6 weeks of planned RFA).
  • Current drug or alcohol use or dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements.
  • Inability or unwillingness of individual or legal guardian/representative to give written informed consent.
