Radiofrequency Ablation Versus Hemithyroidectomy for Small Thyroid Cancers

Condition(s) studied

Investigational drug(s) / intervention(s)

Radiofrequency ablation alone: RFA of a cancer in the thyroid gland.

Surgery: Hemithyroidectomy of the thyroid lobe with cancer

Study summary

This is a multicenter randomized controlled trial including patients with small (\<2 cm) suspected or confirmed thyroid cancers. Patients are included after informed consent and randomized to one of two treatments. One treatment is a standard henithyroidectomy and the second treatment is radiofrequency ablation (RFA) of the specific tumor. The investigators will evaluate initial outcome of the allocated treatment, thyroid hormonal function, oncologic safety, quality of life, and treatment costs in a follow-up period of five years after treatment.

The overall aim of the study is to improve patient's health by reducing the number of operations on small thyroid cancers. In patients with these small tumors, the long-term adverse outcome may be higher than possible benefits from the operation. For participants undergoing surgical treatment with HT, the investigators will measure final histology and both beneficial and adverse outcome from the operation. For participants undergoing RFA, the investigators expect to reduce the need for thyroid hormonal substitutions, reduce the surgical adverse outcomes, reduce treatment costs and increase QoL without a reduction in oncologic safety and outcome.

Eligibility

Primary outcome measure(s)

• Uncomplicated initial treatment (yes/no) — One month after randomization.
  Uncomplicated treatment is defined as a composite endpoint (dichotomous; yes/no) with none of the following adverse outcomes within the first month after treatment/surgery: 1. short or long-term affection of the recurrent laryngeal nerve (RLN) based on laryngoscopy, 2. infection with a need for surgical treatment, 3. capsule rupture or bleeding with a need for operation, 4. prolonged hospital stay (more than one night), 5. any other reason for a secondary surgical intervention on the neck.
