Treatment of Papillary Thyroid Carcinoma With Radiofrequency Ablation

May 15, 2025 updated by: Mayo Clinic

Pilot Study for the Treatment of Papillary Thyroid Carcinoma With Radiofrequency Ablation

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

Conditions

Intervention / Treatment

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.

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Are adults

  • Nodule with Papillary thyroid carcinoma meeting the below criteria:

    • Diagnosed by fine needle aspiration (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 a multifocal papillary thyroid malignancy
  • 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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Changes in Thyroid Nodule Size
Time Frame: 24 months
Thyroid tumor volume shrinkage will be assessed by ultrasound and compared with pre-procedure volume (measure in mL)
24 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pain Related to RFA Procedure
Time Frame: Up to 24 months
Assessed by number of participants that reported any pain related to RFA procedure

18 months
Safety of the RFA Procedure
Time Frame: Up to 24 months
Assessed by the number of participants who experienced infection, hematoma, bruising, or other complications at the RFA site.
Up to 24 months
Change in Thyroid Status
Time Frame: Up to 24 months
Participants were tracked for thyroid status following radiofrequency ablation
Up to 24 months
