However, a thyroid scan can't distinguish between cold nodules that are cancerous and those that aren't cancerous. We either refer too many thyroid patients unnecessarily or order too many ultrasound or other thyroid scans. The proportion of malignancy in Bethesda III nodules confirmed by surgery were significantly increased in proportion relative to K-TIRADS with 60.0% low suspicion, 88.2% intermediate suspicion, and 100% high suspicion nodules (p < 0.001). This equates to 2-3 cancers if one assumes a thyroid cancer prevalence of 5% in the real world. This study has many limitations. 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). Feeling tired more easily. This uses a standardized scoring system for reports providing users with recommendations for when to use fine needle aspiration (FNA) or ultrasound follow-up of suspicious nodules, and when to safely leave alone nodules that are benign/not suspicious. Test performance in the TR3 and TR4 categories had an accuracy of less than 60%. 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. Some patients are good candidates for a scarless thyroid procedure, where the surgeon reaches the thyroid through an incision made on the inside of your lower lip. 202-223-1670, 1892 Preston White Dr. If there are symptoms that indicate the nodule MIGHT be cancer or if there are high risk factors, consulting a oncology endo is a good idea. Each variable is valued at 1 for the presence of the following and 0 otherwise: The above systems were difficult to apply clinically due to their complexity, leading Kwak et al. J. Clin. All rights reserved. Instead, it has been applied on retrospective data sets, with cancer rates far above 5%, rather than on consecutive unselected patients presenting with a thyroid nodule [33]. Cytology result was Bethesda 6. 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]. A proposal for a thyroid imaging reporting and data system for ultrasound features of thyroid carcinoma. 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. Elselvier; 2018. https://www.clinicalkey.com. to propose a simpler TI-RADS in 2011 2. In: Diagnostic Ultrasound. Anti-Cancer Drugs. If a benign thyroid nodule remains unchanged, you may never need treatment. No, say experts at Johns Hopkins Department of Otolaryngology and Head and Neck Surgery. If TIRADS 4and nodule is less than 10 mm, recommend no further investigations, but monitor. In other cases, the nodules can get big enough to cause problems. Some cancers would not show suspicious changes thus US features would be falsely reassuring. However, the ACR TIRADS flow chart with its sharp cutoffs conveys a degree of certainty that may not be valid and may be hard for the clinician to resist. Understanding the risks and harms of management of incidental thyroid nodules: A review. Thyroid nodules are common, very common. 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 pounding heart. Russ G, Royer B, Bigorgne C et-al. Ross DS. The diagnosis or exclusion of thyroid cancer is hugely challenging. After repeat US-guided FNA, some patients achieve a cytological diagnosis, but typically two-thirds remain indeterminate [18], accounting for approximately 20% of initial FNAs (eg, 10%-30% [12], 31% [19], 22% [20]). It has been retrospectively applied to thyroidectomy specimens, which is clearly not representative of the patient presenting with a thyroid nodule [34-36], and has even been used on the same data set used for TIRADS development, clearly introducing obvious bias [32, 37]. In a cost-conscious public health system, one could argue that after selecting out those patients that clearly raise concern for a high risk of cancer (ie, from history including risk factors, examination, existing imaging) the clinician could reasonably inform an asymptomatic patient that they have a 95% chance of their nodule being benign. Often, your doctor will use ultrasound to help guide the placement of the needle. Ferri FF. Management of nodules with initially nondiagnostic results of thyroid fine-needle aspiration: can we avoid repeat biopsy? Reference article, Radiopaedia.org (Accessed on 01 Mar 2023) https://doi.org/10.53347/rID-21448. Elsevier; 2020. https://www.clinicalkey.com. ; Korean Society of Thyroid Radiology (KSThR) and Korean Society of Radiology. TIRADS 1 corresponded to a normal gland, TIRADS 2 to a cystic benign nodule or a spongiform one, TIRADS 3 to a highly probably benign nodule with no US features of suspicion. In some cases, nodules that take up less of the isotope called cold nodules are cancerous. Thyroid nodules. What is TIRADS 3 nodule? The ACR TIRADS management flowchart also does not take into account these clinical factors. 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. Longitudinal ultrasound scan of the right lobe of the thyroid gland shows a solid, isoechoic nodule, measuring 1.5 cm (black arrow) graded as TIRADS 3 by TIRADS ACR and as low suspicion by ATA. Heres what you need to know about thyroid nodules and how concerned you should be if you develop one. 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. The management guidelines may be difficult to justify from a cost/benefit perspective. But your doctor will also want to know if your thyroid is functioning properly. 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. Therefore, using TIRADS categories TR1 or TR2 as a rule-out test should perform very well, with sensitivity of the rule-out test being 97%. A recent meta-analysis comparing different risk stratification systems included 13,000 nodules, mainly from retrospective studies, had a prevalence of cancer of 29%, and even in that setting the test performance of TIRADS was disappointing (eg, sensitivity 74%, specificity 64%, PPV 43%, NPV 84%), and similar to our estimated values of TIRADS test performance [38]. 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. Endocrinol. They're common, almost always noncancerous (benign) and usually don't cause symptoms. Diagnostic approach to and treatment of thyroid nodules. Join endocrinologist Paul Ladenson, M.D., as he outlines the signs and symptoms of the various thyroid disorders and discusses the interplay among other diseases and the thyroid. {"url":"/signup-modal-props.json?lang=us"}, Jha P, Weerakkody Y, Bell D, et al. The widespread use of ultrasonography during the last decades has resulted in a dramatic increase in the prevalence of clinically inapparent thyroid nodules, which only in 5.0-10.0% harbor thyroid carcinoma. Surgery. 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. Thyroid nodules are common, affecting around one-half of the population and become increasingly common with advancing age [1, 2]. However, today more limited surgery to remove only half of the thyroid may be appropriate for some cancerous nodules. 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.

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]. An ultrasonogram reporting system for thyroid nodules stratifying cancer risk for clinical management. All thyroid nodules were scored with the French TIRADS flowchart, already described by our team ( 1, 10 ). Is it time to panic? The vast majority more than 95% of thyroid nodules are benign (noncancerous). Surgery results were unavailable. American Thyroid Association. Compared with randomly doing FNA on 1 in 10 nodules, using ACR TIRADS and doing FNA on all TR5 requires NNS of 50 to find 1 additional cancer. The findings that ACR TIRADS has methodological concerns, is not yet truly validated, often performs no better than random selection, and drives significant costs and potential harm, are very unsettling but result from a rational and scientific assessment of the foundational basis of the ACR TIRADS system. Thyroid nodules are very common, especially in the U.S. Check for errors and try again. TI-RADS 2: Benign nodules. In: Goldman-Cecil Medicine. Following ACR TIRADS management guidelines would likely result in approximately one-half of the TR3 and TR4 patients getting FNAs ((0.537)+(0.323)=25, of total 60), finding up to 1 cancer, and result in 4 diagnostic hemithyroidectomies for benign nodules (250.20.8=4). Bongiovanni M, Spitale A, Faquin WC, Mazzucchelli L, Baloch ZW. The TIRADS reporting algorithm is a significant advance with clearly defined objective sonographic features that are simple to apply in practice. Accessed Oct. 31, 2019. 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. Radiographic features Ultrasound If one assumes that they do, then it is important to note that 25% of patients make up TR1 and TR2 and only 16% of patients make up TR5. 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 current ACR TIRADS system changed from that assessed during training, with the addition of the taller-than-wide and size criteria, which further questions the assumption that the test should perform in the real world as it did on a the initial training data set. In response, ACR committees were formed to accomplish three goals: Develop management guidelines for nodules that are discovered incidentally on CT, MRI, PET or ultrasound. Hyperfunctioning thyroid nodules can be treated with surgery or radioactive iodine ablation. 5th ed. Check out these best-sellers and special offers on books and newsletters from Mayo Clinic Press. A negative result with a highly sensitive test is valuable for ruling out the disease. Whilst our findings have illustrated some of the shortcomings of ACR TIRADS guidelines, we are not able to provide the ideal alternative. In: Conn's Current Therapy 2019. 7. During this test, an isotope of radioactive iodine is injected into a vein in your arm. Accessed Oct. 31, 2019. 2016; doi:10.1038/nrendo.2016.110. However, the consequent management guidelines are difficult to justify at least on a cost basis for a rule-out test, though ACR TIRADS may provide more value as a rule-in test for a group of patients with higher cancer risk.

We have detailed the data set used for the development of ACR TIRADS [16] in Table 1, plus noted the likely cancer rates in the real world if one assumes that the data set cancer prevalence (10.3%) is double that in the population upon which the test is intended to be used (pretest probability of 5%). Perhaps the most relevant positive study is from Korea, which found in a TR4 group the cancer rate was no different between nodules measuring between 1-2 cm (22.3%) and those 2-3 cm (23.5%), but the rate did increase above 3 cm (40%) [24]. 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. To further enhance the performance of TIRADS, we presume that patients present with only 1 TR category of thyroid nodules. Quite where the cutoff should be is debatable, but any cutoff below TR5 will have diminishing returns and increasing harms. 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. In response, ACR committees were formed to accomplish three goals: License Information The detection rate of thyroid cancer has increased steeply with widespread utilization of ultrasound (US) and frequent incidental detection of thyroid nodules with other imaging modalities such as computed tomography, magnetic resonance imaging, and, more recently, positron emission tomography-computed tomography, yet the mortality from thyroid cancer has remained static [10, 11]. Second, the proportion of patients in the different ACR TIRADS (TR) categories may, or may not, reflect the real-world population (Table 1). The more FNAs done in the TR3 and TR4 groups, the more indeterminate FNAs and the more financial costs and unnecessary operations. Thyroid nodules. Explore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this condition. Accessed Nov. 4, 2019. He or she will also check for signs and symptoms of hypothyroidism, such as a slow heartbeat, dry skin and facial swelling. Elselvier; 2018. https://www.clinicalkey.com. The system is sometimes referred to as TI-RADS Kwak 6. Performing FNA on TR5 nodules is a relatively effective way of finding thyroid cancers. However, if the concern is that this might miss too many thyroid cancers, then this could be compared with the range of alternatives (ie, doing no tests or doing many more FNAs). The financial costs and surgical morbidity in this group must be taken into account when considering the cost/benefit repercussions of a test that includes US imaging for thyroid cancer. This content does not have an English version. in 2009 1. Treating nodules that cause hyperthyroidism If a thyroid nodule is producing thyroid hormones, overloading your thyroid gland's normal hormone production levels, your doctor may recommend treating you for hyperthyroidism. This may include: Radioactive iodine. If you assume that FNA is done as per reasonable application of TIRADS recommendations (in all patients with TR5 nodules, one-half of patients with TR4 nodules and one-third of patients with TR3 nodules) and the proportion of patients in the real world have roughly similar proportion of TR nodules as the data set used, then 100 US scans would result in FNAs of about one-half of all patients scanned (of data set, 16% were TR5, 37% were TR4, and 23% were TR3, so FNA number from 100 scans=16+(0.537)+(0.323)=42). 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. 2011;260 (3): 892-9. Mayo Clinic is a not-for-profit organization. Anderson TJ, Atalay MK, Grand DJ, Baird GL, Cronan JJ, Beland MD. 2009;94 (5): 1748-51. If a thyroid nodule isn't cancerous, treatment options include: Watchful waiting. Any test will struggle to outperform educated guessing to rule out clinically important thyroid cancer. 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. Whether its benign or not, a bothersome thyroid nodule can often be successfully managed. You then lie on a table while a special camera produces an image of your thyroid on a computer screen. published a simplified TI-RADS that was prospectively validated 5. This assumption is obviously not valid and favors TIRADS management guidelines, but we believe it is helpful for clarity and illustrative purposes. A radioactive iodine scan uses a radioactive form of iodine and a special camera to detect thyroid cancer cells in your body. The gender bias (92% female) and cancer prevalence (10%) of the data set suggests it may not accurately reflect the intended test population. ACR TIRADS has not been applied to a true validation set upon which it is intended to be used, and therefore needs to be considered with caution when applying it to the real-world situation. 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. 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. Reston, VA 20191 The probability of malignancy was based on an equation derived from 12 features 2. However, these assumptions have intentionally been made to favor the expected performance of ACR-TIRADS, and so in real life ACR-TIRADS can be expected to perform less well than we have illustrated. Very probably benign nodules are those that are both. (2017) Radiology. If a guideline indicates that FNA is recommended, it can be difficult to oppose this based on other factors. So, the number needed to scan (NNS) for each additional person correctly reassured is 100 (NNS=100). If the proportions of patients in the different TR groups in the ACR TIRADs data set is similar to the real-world population, then the prevalence of thyroid cancer in the TR3 and TR4 groups is lower than in the overall population of patients with thyroid nodules. The actual number of inconclusive FNA results in the real-world validation set has not been established (because that study has not been done), but the typical rate is 30% (by this we mean nondiagnostic [ie, insufficient cells], or indeterminate [ie, atypia of undetermined significance (AUS)/follicular lesion of undetermined significance (FLUS)/follicular neoplasm/suspicious for follicular neoplasm [Bethesda I, III, IV]). 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). Choosing an experienced specialist can mean more options to help personalize your treatment and achieve better results. A thyroid nodule is an unusual lump (growth) of cells on your thyroid gland. A robust validation study is required before the performance and cost-benefit outcomes of any of the TIRADS systems can be known. Make a donation. Using TR5 as a rule-in test was similar to random selection (specificity 89% vs 90%). To get the most from your appointment, try these suggestions: Mayo Clinic does not endorse companies or products.

Authors If a thyroid nodule is producing thyroid hormones, overloading your thyroid gland's normal hormone production levels, your doctor may recommend treating you for hyperthyroidism. The performance of any diagnostic test in this group has to be truly exceptional to outperform random selection and accurately rule in or rule out thyroid cancer in the TR3 or TR4 groups. During the procedure, your doctor inserts a very thin needle in the nodule and removes a sample of cells. 1. Accessed Oct. 31, 2019. Metab. If the doctor recommends removal of your thyroid (thyroidectomy), you may not even have to worry about a scar on your neck. Nodules that are TIRADS 3 have a low risk of important thyroid cancer, probably 1 to 5%. Washington, DC 20004 However, most of the sensitivity benefit is due to the performance in the TR1 and TR2 categories, with sensitivity in just the TR3 and TR4 categories being only 46% to 62%, depending on whether the size cutoffs add value (data not shown). Memory problems. Refer to separate articles for the latest systems supported by various professional societies: A TI-RADS was first proposed by Horvath et al. 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. The key next step for any of the TIRADS systems, and for any similar proposed test system including artificial intelligence [30-32], is to perform a well-designed prospective validation study to measure the test performance in the population upon which it is intended for use. We found sensitivity and PPV with TIRADS was poor, but was better than random selection (sensitivity 53% vs 1%, and PPV 34% vs 1%) whereas specificity, NPV, and accuracy was no better with TIRADS compared with random selection (specificity 89% vs 90%, NPV 94% vs 95%, and accuracy 85% vs 85%), Table 2 [25]. Mayo Clinic. The ACR-TIRADS guidelines also provide easy-to-follow management recommendations that have understandably generated momentum.

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. Kwak JY, Han KH, Yoon JH et-al. Tests include: Physical exam. PLoS ONE. 703-390-9883, Looking for a Specific Department? Recently, the American College of Radiology (ACR) proposed a Thyroid Imaging Reporting and Data System (TI-RADS) for thyroid nodules based on ultrasonographic features. Your doctor will also look for signs and symptoms of hyperthyroidism, such as tremor, overly active reflexes, and a rapid or irregular heartbeat. In the TR3 category, there was a gradual difference in cancer rate in those 1-2 cm (6.5%), and those 2-3 cm (8.4%) and those>3 cm (11.3%). The prevalence of incidental thyroid cancer at autopsy is around 10% [3]. TIRADS does not perform to this high standard. American Thyroid Association. Both TI-RADS classifications can safely avert avoidable FNACs in a significant proportion of benign thyroid lesions. What is TIRADS 4 nodule? Until a well-designed validation study is completed, the performance of TIRADS in the real world is unknown. It may also include an ultrasound. Category definitions TI-RADS 1: normal thyroid gland TI-RADS 2 : benign conditions (0% risk of malignancy) TI-RADS 3: probably benign nodules (<5% malignancy) TI-RADS 4: suspicious nodules (5-80% malignancy) It is this proportion of patients that often go on to diagnostic hemithyroidectomies, from which approximately 20% are cancers [12, 17, 21], meaning the majority (80%) end up with ultimately unnecessary operations. This site complies with the HONcode standard for trustworthy health information: verify here. Learn about what we offer at our center. The costs depend on the threshold for doing FNA. 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. If you see or feel a thyroid nodule yourself usually in the middle of your lower neck, just above your breastbone call your primary care doctor for an appointment to evaluate the lump. Once the test is considered to be performing adequately, then it would be tested on a validation data set. Applying ACR-TIRADS across all nodule categories did not perform well, with sensitivity and specificity between 60% and 80% and overall accuracy worse than random selection (65% vs 85%). Your thyroid specialist will help determine the correct amount to take because it may require more than hormone replacement to manage your cancer risk. Putting aside any potential methodological concerns with ACR TIRADS, it may be helpful to illustrate how TIRADS might work if one assumed that the data set used was a fair approximation to the real-world population.
