|Thyroid Nodule Thyroid Cancer Thyroid Neoplasms Nodular Goiter||Procedure: Laser Ablation of Thyroid Nodule|
|Study Design:||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Pilot Study on Laser Ablation of Symptomatic Benign Thyroid Masses|
- The primary goal of this study is to determine the local response of laser ablation of the treated lesion and its effect on size and vascularity. The objective measures will be based on serial US with Doppler. [ Time Frame: 12 months ]
- To assess the effects of laser ablation on thyroid function testing. An estimate of time and cost associated with LITT procedure for treatment of soft tissue thyroid nodules. [ Time Frame: 12 months ]

|Primary Completion Date:||January 2011 (Final data collection date for primary outcome measure)|
Procedure: Laser Ablation of Thyroid Nodule
- PhoTex15 Diode Laser
- Visualase Cooled Laser Applictor System
Thyroid nodules are a very common clinical finding, with an estimated prevalence (based on palpation) ranging from 3% to 7% among the general population. With the widespread use of ultrasound (US), clinically unapparent thyroid nodule prevalence has dramatically increased with estimates at 20% to 76% in the general population. Moreover, 20% to 48% of patients with a single palpable thyroid nodule are found to have additional nodules when investigated by US.
Laser ablation therapy offer potential for the thermal destruction of soft tissue structures. The ability to deliver large doses of energy via small flexible fiberoptics makes laser therapy ideally suited for percutaneous treatment of unwanted tissue masses.
In this study we propose to treat symptomatic soft tissue thyroid masses in the head and neck region using a new FDA-cleard laser ablation system to safely and effectively debulk the tissue and therefore improve symptoms. Real time US monitoring will be performed of the ablation front to ensure complete treatment of the target lesion. All ablated regions will be followed by US with Doppler to document changes in size and vascularity. Local effects on thyroid function for thyroid mass treatment will be measured on follow-up.
