Thyroid imaging reporting and data system (TI-RADS). Thyroid nodules. It is important to validate this classification in different centres. The TIRADS reporting algorithm is a significant advance with clearly defined objective sonographic features that are simple to apply in practice. Thyroid nodules come to clinical attention when noted by the patient; by a clinician during routine physical examination; or during a radiologic procedure, such as carotid ultrasonography, neck or chest computed tomography (CT), or positron emission tomography (PET) scanning. These figures cannot be known for any population until a real-world validation study has been performed on that population. Anderson TJ, Atalay MK, Grand DJ, Baird GL, Cronan JJ, Beland MD. Kwak JY, Han KH, Yoon JH et-al. Until a well-designed validation study is completed, the performance of TIRADS in the real world is unknown. In: Rosai and Ackerman's Surgical Pathology. 1. Such guidelines do not detail the absolute risk of finding or missing a cancer, nor the often excellent outcome of the treatment of thyroid cancer, nor the potential for unnecessary operations. You then lie on a table while a special camera produces an image of your thyroid on a computer screen.

However, today more limited surgery to remove only half of the thyroid may be appropriate for some cancerous nodules. If one decides to FNA every TR5 nodule, from the original ACR TIRADS data set, 34% were found to be cancerous, but note that this data set likely has double the prevalence of thyroid cancer compared with the real-world population. The ACR-TIRADS guidelines also provide easy-to-follow management recommendations that have understandably generated momentum. 6. Ultrasound (US) risk-stratification systems for investigation of thyroid nodules may not be as useful as anticipated. 202-223-1670, 1892 Preston White Dr. Hypothyroidism. Because the data set prevalence of thyroid cancer was 10%, compared with the generally accepted lower real-world prevalence of 5%, one can reasonably assume that the actual cancer rate in the ACR TIRADS categories in the real world would likely be one-half that quoted from the ACR TIRADS data set, which we illustrate in the following section. Learn about what we offer at our center. First, 10% of FNA or histology results were excluded because of nondiagnostic findings [16]. Accessed Oct. 31, 2019. The following article describes the initial iterations proposed by individual research groups, none of which gained widespread use. Second, we then apply TIRADS across all 5 nodule categories to give an idea how TIRADS is likely to perform overall. 7. However, in the data set, only 25% of all nodules were categorized as TR1 or TR2 and these nodules harbored only 1% of all thyroid cancers (9 of 343). The summary of test performance of random selection, ACR TIRADS as a rule-out test, ACR TIRADS as a rule-in test, and ACR TIRADS applied across all TIRADS categories are detailed in Table 2, and the full data, definitions, and calculations are given elsewhere [25]. Permissions beyond the scope of this license may be available here. The gender bias (92% female) and cancer prevalence (10%) of the data set suggests it may not accurately reflect the intended test population.

Background Thyroid cancer diagnosis has evolved to include computer-aided diagnosis (CAD) approaches to overcome the limitations of human ultrasound feature assessment. Hypoechoic thyroid nodules appear dark relative to the surrounding tissue. As noted previously, we intentionally chose the clinical comparator to be relatively poor and not a fair reflection of real-world practice, to make it clearer to what degree ACR TIRADS adds value. This allows patients with a TR1 or TR2 nodule to be reassured that they have a low risk of thyroid cancer, rather than a mixture of nodules (not just TR1 or TR2) not being able to be reassured. He or she will also check for signs and symptoms of hypothyroidism, such as a slow heartbeat, dry skin and facial swelling. Endocrinol. Goldman L, et al., eds. 215-574-3150, 1100 Wayne Ave., Suite 1020 Based on the methodology used to acquire the data set, the gender bias, and cancer rate in the data set, it is unlikely to be a fair reflection of the population upon which the test is intended to be applied, and so cannot be considered a true validation set. American Thyroid Association. A minority of these nodules are cancers. For every 100 FNAs performed, about 30 are inconclusive, with most (eg, 20% of the original 100) remaining indeterminate after repeat FNA and requiring diagnostic hemithyroidectomy. Thyroid cancer is one of the most treatable kinds of cancer. If the doctor recommends removal of your thyroid (thyroidectomy), you may not even have to worry about a scar on your neck. Patients and methods: 80 patients with at least one EU-TIRADS 5 nodule 10 mm and no suspicious lymph nodes, accepting active surveillance, were included. However, given that TR1 and TR2 make up only 25% of the nodules, then to find 25 nodules that are TR1 or TR2, you would need to do 100 scans. Cytology result was Bethesda 6. Thyroid imaging reporting and data system (TI-RADS)refers to any of several risk stratification systems for thyroid lesions, usually based on ultrasound features, with a structure modelled off BI-RADS. It is limited by only being an illustrative example that does not take clinical factors into account such as prior radiation exposure and clinical features.

The more important test metric for diagnosing a disease is the specificity, where a positive test helps rule-in the disease. To show the best possible performance of ACR TIRADS, we are comparing it to clinical practice in the absence of TIRADS or other US thyroid nodule stratification tools, and based on a pretest probability of thyroid cancer in a nodule being 5%, where 1 in 10 nodules are randomly selected for FNA. Quite where the cutoff should be is debatable, but any cutoff below TR5 will have diminishing returns and increasing harms. Your doctor then sends the samples to a laboratory to have them analyzed under a microscope. This study aimed to assess the performance and costs of the American College of Radiology (ACR) Thyroid Image Reporting And Data System (TIRADS), by first looking for any important issues in the methodology of its development, and then illustrating the performance of TIRADS for the initial decision for or against FNA, compared with an imagined clinical comparator of a group in which 1 in 10 nodules were randomly selected for FNA. Such validation data sets need to be unbiased. However, a thyroid scan can't distinguish between cold nodules that are cancerous and those that aren't cancerous. Furuya-Kanamori L, Bell KJL, Clark J, Glasziou P, Doi SAR. Interobserver Agreement of Thyroid Imaging Reporting and Data System (TIRADS) and Strain Elastography for the Assessment of Thyroid Nodules. At best, only a minority of the 3% of cancers would show on follow-up imaging features suspicious for thyroid cancer that correctly predict malignancy. Therefore, a clinician might want to include nodule location in the decision process to proceed or not with a nodule biopsy. Trouble sleeping. The consequences of these proportions are highly impactful when considering the real-world performance of ACR-TIRADS. The main source data set for the ACR TIRADS recommendations was large and consisted of US images and FNA results of more than 3400 nodules [16]. Also see your doctor if you have signs and symptoms that may mean your thyroid gland isn't making enough thyroid hormone (hypothyroidism), which include: Feeling cold. Apr 29, 2021. Therefore, the rates of cancer in each ACR TIRADS category in the data set where they used four US characteristics can no longer be assumed to be the case using the 5 US characteristics plus the introduction of size cutoffs. Such data should be included in guidelines, particularly if clinicians wish to provide evidence-based guidance and to obtain truly informed consent for any action that may have negative consequences. 2018; doi:10.3322/caac.21447. This may include: Treatment for a nodule that's cancerous usually involves surgery. If a thyroid nodule is causing voice or swallowing problems, your doctor may recommend treating it with surgery to remove all or part of the thyroid gland. The more carefully one looks for incidental asymptomatic thyroid cancers at autopsy, the more are found [4], but these do not cause unwellness during life and so there is likely to be no health benefit in diagnosing them antemortem. If a patient presented with symptoms (eg, concerns about a palpable nodule) and/or was not happy accepting a 5% pretest probability of thyroid cancer, then further investigations could be offered, noting that US cannot reliably rule in or rule out thyroid cancer for the majority of patients, and that doing any testing comes with unintended risks. Nodules with a sum of 3 points are defined as TR3 or "mildly suspicious" - the guidelines recommend fine needle aspiration of the nodule in question is 2.5cm in size or greater, with follow-ups and subsequent ultrasounds recommended if the nodules are larger than 1.5cm. Diagnosis and Management of Small Thyroid Nodules: A Comparative Study with Six Guidelines for Thyroid Nodules. The proportion of malignancy in AUS and FLUS were . The cost of seeing 100 patients and only doing FNA on TR5 is at least NZ$100,000 (compared with $60,000 for seeing all patients and randomly doing FNA on 1 in 10 patients), so being at least NZ$20,000 per cancer found if the prevalence of thyroid cancer in the population is 5% [25]. Haymart MR, Banerjee M, Reyes-Gastelum D, Caoili E, Norton EC. proposed a system with five categories, which, like BI-RADS, each carried a management recommendation 2. Routine FNA of this group is more likely to lead to false positive . Bongiovanni M, Spitale A, Faquin WC, Mazzucchelli L, Baloch ZW. American Thyroid Association. Tests include: Physical exam. Near-total thyroidectomy may be used depending on the extent of the disease. Thyroid. The other one-half of the cancers that are missed by only doing FNA of TR5 nodules will mainly be in the TR3 and TR4 groups (that make up 60% of the population), and these groups will have a 3% to 8% chance of cancer, depending upon whether the population prevalence of thyroid cancer in those being tested is 5% or 10%. All thyroid nodules were scored with the French TIRADS flowchart, already described by our team ( 1, 10 ).

Tom James Cawood, Georgia Rose Mackay, Penny Jane Hunt, Donal OShea, Stephen Skehan, Yi Ma, TIRADS Management Guidelines in the Investigation of Thyroid Nodules; Illustrating the Concerns, Costs, and Performance, Journal of the Endocrine Society, Volume 4, Issue 4, April 2020, bvaa031, https://doi.org/10.1210/jendso/bvaa031. The specificity of TIRADS is high (89%) but, perhaps surprisingly, is similar to randomly selecting of 1 in 10 nodules for FNA (90%). The optimal investigation and management of the 84% of the population harboring the remaining 50% of cancer remains unresolved. The financial cost depends on the health system involved, but as an example, in New Zealand where health care costs are modest by international standards in the developed world, compared with randomly selecting 1 in 10 nodules for FNA, using ACR TIRADS would result in approximately NZ$140,000 spent for every additional patient correctly reassured that he or she does not have thyroid cancer [25]. In the past, it was standard to remove a majority of thyroid tissue a procedure called near-total thyroidectomy. Nodules located in the thyroid isthmus are at greater risk of being malignant than those found in the lateral lobes, whereas those in the lower portion of the lobes are at least risk. Hoang JK, et al. This assumption is obviously not valid and favors TIRADS management guidelines, but we believe it is helpful for clarity and illustrative purposes. If a patient was happy taking this small risk (and particularly if the patient has significant comorbidities), then it would be reasonable to do no further tests, including no US, and instead do some safety netting by advising the patient to return if symptoms changed (eg, subsequent clinically apparent nodule enlargement). Ultimately, most of these turn out to be benign (80%), so for every 100 FNAs, you end up with 16 (1000.20.8) unnecessary operations being performed. Summary Test Performance of Random Selection of 1 in 10 Nodules for FNA, Compared with ACR-TIRADS. If a thyroid nodule is causing voice or swallowing problems, your doctor may recommend treating it with surgery to remove all or part of the thyroid gland. We are vaccinating all eligible patients. Russ G, Royer B, Bigorgne C et-al. Noticeably benign pattern (0% risk of malignancy) TI-RADS 3: Probably benign nodules (<5% risk of malignancy) TI-RADS 4: 4a - Undetermined nodules (5-10% risk of malignancy) Score of 1. People who undergo thyroid gland surgery may need to take thyroid hormone afterward to keep their body chemistry in balance.

It has not been shown to be effective and is associated with an increased risk of cardiac arrythmia and osteoporosis. Thyroid cancer. Elselvier; 2018. https://www.clinicalkey.com. A TR5 cutoff would have NNS of 50 per additional cancer found compared with random FNA of 1 in 10 nodules, and probably a higher NNS if one believes that clinical factors can increase FNA hit rate above the random FNA hit rate.

Authors An ultrasonogram reporting system for thyroid nodules stratifying cancer risk for clinical management. It is very difficult to know the true prevalence of important, clinically consequential thyroid cancers among patients presenting with thyroid nodules. (2009) Thyroid : official journal of the American Thyroid Association. This is likely an underestimate of the number of scans needed, given that not all nodules that are TR1 or TR2 will have purely TR1 or TR2 nodules on their scan. We realize that such factors may increase an individuals pretest probability of cancer and clinical decision-making would change accordingly (eg, proceeding directly to FNA), but we here ascribe no additional diagnostic value to avoid overestimating the performance of the clinical comparator. We refer to ACR-TIRADS where data or comments are specifically related to ACR TIRADS and use the term TIRADS either for brevity or when comments may be applicable to other TIRADS systems. Other limitations include the various assumptions we have made and that we applied ACR TIRADS to the same data set upon which is was developed. Any use of this site constitutes your agreement to the Terms and Conditions and Privacy Policy linked below. In 2013, Russ et al. Third, when moving on from the main study in which ACR TIRADS was developed [16] to the ACR TIRADS white paper recommendations [22], the TIRADS model changed by the addition of a fifth US characteristic (taller than wide), plus the addition of size cutoffs. What is TIRADS 4 nodule? Some are solid, and some are fluid-filled cysts. 2011;260 (3): 892-9. Radiofrequency ablation uses a probe to access the benign nodule under ultrasound guidance, and then treats it with electrical current and heat that shrinks the nodule. Department of Endocrinology, Christchurch Hospital. Washington, DC 20004 If a benign thyroid nodule remains unchanged, you may never need treatment. There are even data showing a negative correlation between size and malignancy [23]. We found better sensitivity, PPV, and NPV with TIRADS compared with random selection (97% vs 1%, 13% vs 1%, and 99% vs 95%, respectively), whereas specificity and accuracy were worse with TIRADS compared with random selection (27% vs 90%, and 34% vs 85%, respectively (Table 2)[25]. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. TI-RADS 2: Benign nodules. Accessed Dec. 6, 2019. A negative result with a highly sensitive test is valuable for ruling out the disease. The equation was as follows: z = -2.862 + 0.581X1- 0.481X2- 1.435X3+ 1.178X4+ 1.405X5+ 0.700X6+ 0.460X7+ 0.648X8- 1.715X9+ 0.463X10+ 1.964X11+ 1.739X12. This usually means having a physical exam and thyroid function tests at regular intervals. Hong MJ, Na DG, Baek JH, Sung JY, Kim JH. This data set was a subset of data obtained for a previous study and there are no clear details of the inclusion and exclusion criteria, including criteria for FNA.

Furthermore, we are presuming other clinical factors (ie, palpability, size, number, symptoms, age, gender, prior radiation exposure, family history) add no diagnostic value above random selection. American College of Radiology-Thyroid Imaging, Reporting and Data System (ACR-TIRADS) has been promoted as an improvement to existing guidelines such as the 2015 revised American Thyroid Association (ATA) guidelines.

Ferri FF. Accessed Oct. 31, 2019. The American College of Radiology Thyroid Imaging Reporting and Data Systems (TIRADS) is a 5 point classification to determine the risk of cancer in thyroid nodules based on ultrasound characteristics. These final validation sets must fairly represent the population upon which the test is intended to be applied because the prevalence of the condition in the test population will critically influence the test performance, particularly the positive predictive value (PPV) and negative predictive value (NPV). But your doctor will also want to know if your thyroid is functioning properly. http://www.thyroid.org/thyroid-nodules/. {"url":"/signup-modal-props.json?lang=us"}, Jha P, Weerakkody Y, Bell D, et al. Thus, the absolute risk of missing important cancer goes from 5% (with no FNAs) to 2.5% using TIRADS and FNA of all TR5, so NNS=100/2.5=40. We chose a 1 in 10 FNA rate to reflect that roughly 5% of thyroid nodules are palpable and so would likely go forward for FNA, and we considered that a similar number would be selected for FNA based on clinical grounds such as other risk factors or the patient wishes. Very probably benign nodules are those that are both. After a median follow-up of 36.1 months, a volumetric increase 50% occurred in 28 . Full data including 95% confidence intervals are given elsewhere [25]. Sensitivity of ACR TIRADS was better than random selection, between 74% to 81% (depending on whether the size cutoffs add value) compared with 1% with random selection. Accessed Oct. 31, 2019. Many of these papers share the same fundamental problem of not applying the test prospectively to the population upon which it is intended for use. The vast majority of nodules followed-up would be benign (>97%), and so the majority of FNAs triggered by US follow-up would either be benign, indeterminate, or false positive, resulting in more potential for harm (16 unnecessary operations for every 100 FNAs). J. Clin. 703-390-9883, Looking for a Specific Department? Elsevier; 2019. https://www.clinicalkey.com. Recently, the American College of Radiology (ACR) proposed a Thyroid Imaging Reporting and Data System (TI-RADS) for thyroid nodules based on ultrasonographic features. The authors stated that TI-RADS 4 and 5 nodules must be biopsied. The costs depend on the threshold for doing FNA. Dry skin. Therefore, for every 25 patients scanned (100/4=25) and found to be either TR1 or TR2, 1 additional person would be correctly reassured that they do not have thyroid cancer. The figures that TIRADS provide, such as cancer prevalence in certain groups of patients, or consequent management guidelines, only apply to populations that are similar to their data set. TI-RADS categories Composition Cyst Spongiform Mixed cystic/solid Solid lesions Echogenicity Shape Margin Echogenic foci Given that ACR TIRADS test performance is at its worst in the TR3 and TR4 groups, then the cost-effectiveness of TIRADS will also be at its worst in these groups, in particular because of the false-positive TIRADS results. Therefore, 60% of patients are in the middle groups (TR3 and TR4), where the US features are less discriminatory. TI-RADS 4b applies to the lesion with one or two of the above signs and no metastatic lymph node is present. A study that looked at all nodules in consecutive patients (eg, perhaps FNA of every nodule>10 mm) would be required to get an accurate measure of the cancer prevalence in those nodules that might not typically get FNA. A thyroid nodule is an unusual lump (growth) of cells on your thyroid gland. Our thyroid experts in the head and neck endocrine surgery team diagnose and treat patients with a variety of thyroid and parathyroid conditions. In: Goldman-Cecil Medicine. This comes at the cost of missing as many cancers as you find, spread amongst 84% of the population, and doing 1 additional unnecessary operation (160.20.8=2.6, minus the 1.6 unnecessary operations resulting from random selection of 1 in 10 patients for FNA [25]), plus the financial costs involved. To get the most from your appointment, try these suggestions: Mayo Clinic does not endorse companies or products. Risks of thyroid surgery include damage to the nerve that controls your vocal cords and damage to your parathyroid glands four tiny glands located on the back of your thyroid that help control your body's levels of minerals, such as calcium. Whilst the details of the design of the final validation study can be debated, the need for a well-designed validation study to determine the test characteristics in the real-world setting is a basic requirement of any new test. 1998-2023 Mayo Foundation for Medical Education and Research (MFMER). At Another Johns Hopkins Member Hospital: The Johns Hopkins Thyroid and Parathyroid Center, Webinar: Thyroid Disease, an Often Surprising Diagnosis, Masks are required inside all of our care facilities, COVID-19 testing locations on Maryland.gov, Radiofrequency Ablation for Thyroid Nodules. Thyroid nodules are detected by ultrasonography in up to 68% of healthy patients. In some cases, nodules that take up less of the isotope called cold nodules are cancerous. Eur. For the calculations, we assume an approximate size distribution where one-third of TR3 nodules are25 mm and half of TR4 nodules are15 mm. The system is sometimes referred to as TI-RADS Kwak 6. 2020 Mar 10;4 (4):bvaa031. Doctors use radioactive iodine to treat hyperthyroidism. PPV was poor (20%), NPV was no better than random selection, and accuracy was worse than random selection (65% vs 85%). The NNS for ACR TIRADS is such that it is hard to justify its use for ruling out thyroid cancer (NNS>100), at least on a cost/benefit basis. For TIRADS to add clinical value, it would have to clearly outperform the comparator (random selection), particularly because we have made some assumptions that favor TIRADS performance.
