Percutaneous interstitial laser photocoagulation (ILP) effectively ablates thyroid tissue in glands without cystic areas. This laser treatment shows potential for selected recurrent thyroid cancer cases unresponsive to other therapies.

Area of Science:

  • Endocrinology
  • Oncology
  • Minimally Invasive Surgery

Background:

  • Recurrent thyroid carcinoma poses treatment challenges, especially when surgery or radioiodine are not viable options.
  • Palliative treatment strategies are crucial for managing advanced or recurrent thyroid cancer.

Purpose of the Study:

  • To assess percutaneous interstitial laser photocoagulation (ILP) as a palliative treatment for recurrent thyroid carcinoma.
  • To evaluate the feasibility and efficacy of ILP in thyroid tissue ablation.

Main Methods:

  • Utilized 18 resected thyroid glands to analyze ILP-induced damage volume and histology.
  • Assessed in vivo treatment feasibility using low-energy laser in two volunteers.
  • Employed ultrasonographic (US) monitoring for needle insertion and a Nd:YAG laser for irradiation (2-7 W).

Main Results:

  • Histological analysis confirmed well-defined tissue ablation, with area correlating to laser parameters (0-26 mm).
  • Ultrasonography did not accurately predict the extent of laser-induced lesions.
  • In vivo ILP was performed without complications, demonstrating technical feasibility.

Conclusions:

  • Interstitial laser photocoagulation creates predictable tissue ablation in thyroid glands lacking cystic components.
  • ILP presents a potential therapeutic option for highly selected thyroid tumor treatment scenarios.
