And in one case, a hospital has taken the unique step of forming a multidisciplinary thyroid nodule RFA tumor board, which helps in the often tricky decision-making process that is involved.
“Our multidisciplinary RFA tumor board has been invaluable in this process, and it is the only one of its kind in the nation that I’m aware of,” James Lim, MD, of the Division of Surgical Oncology, Thyroid, and Parathyroid Center at Oregon Health Sciences University (OHSU), told this news organization.
Dr. Lim reports receiving referrals from “all avenues, some from thyroid specialists and others from nonthyroid specialists such as primary care practitioners or patient self-referrals.”
“Because of this, our centralized process of multidisciplinary review ensures that each patient is evaluated thoroughly through each thyroid specialists’ lens to optimize patient outcomes,” noted Dr. Lim, an assistant professor of endocrine surgery.
The RFA tumor board consists of experts in all specialties involved in thyroid nodule assessment and treatment, including surgeons, interventional radiologists, and endocrinologists.
Just because you can, doesn’t mean you should
However, there should be some caution that although there is enthusiasm regarding this noninvasive alternative to surgery, there is another option, that of mere observation, which is appropriate in many cases of thyroid nodules and should not be overlooked.
“For a number of reasons, the key to keep in mind is that, just because we can do something doesn’t mean we should,” Michael Singer, MD, director of the Division of Thyroid & Parathyroid Surgery, Department of Otolaryngology – Head and Neck Surgery, at the Henry Ford Health System, Detroit, said in an interview.
While emphasizing that he believes RFA to be a promising technology that will likely benefit patients in the future, Dr. Singer voiced concern about the approach becoming an easy choice – particularly if profit is to be had – when observation is a clear alternative. “If RFA becomes seen as an opportunity to create revenue, potential conflicts of interest may arise,” he said.
“As it is not a major procedure with a dramatic risk profile, my concern is that some clinicians [could] adopt the attitude of ‘Why not do it?’ even when the indication is minimal or nonexistent,” he added.
Dr. Lim said he agrees that “any new medical technology requires thoughtful evaluation and appropriate patient selection in order to ensure optimal patient outcomes.”
That’s where the tumor board has been especially beneficial.
“We have found great benefit in reviewing potential RFA cases in a multidisciplinary fashion within our tumor board and would recommend other institutions to consider it,” he noted. In the absence of a tumor board, “at a minimum, a thyroid specialist should be involved in the evaluation of a potential thyroid RFA patient prior to ablation treatment,” he advised.
Tumor board was able to identify a small subset of patients for surgery
In his research presented at the 90th Annual Meeting of the American Thyroid Association (ATA), Dr. Lim and colleagues evaluated the tumor board’s efficacy in altering diagnosis and treatment plans in a retrospective review of cases presented to the board for RFA consideration since its inception in July 2020 through June 2021.
