Kitahara CM, et al. The chance of finding cancer is 1 in 20, whereas the chance of testing resulting in an unnecessary operation is around 1 in 7. 202-223-1670, 1892 Preston White Dr.
The present study evaluated the risk of malignancy in solid nodules>1 cm using ACR TI-RADS. Background Thyroid cancer diagnosis has evolved to include computer-aided diagnosis (CAD) approaches to overcome the limitations of human ultrasound feature assessment. The low pretest probability of important thyroid cancer and the clouding effect of small clinically inconsequential thyroid cancers makes the development of an effective real-world test incredibly difficult. It should also be on an intention-to-test basis and include the outcome for all those with indeterminate FNAs. Cavallo A, Johnson DN, White MG, et al. The prevalence of incidental thyroid cancer at autopsy is around 10% [3]. PPV was poor (20%), NPV was no better than random selection, and accuracy was worse than random selection (65% vs 85%). Recently, the American College of Radiology (ACR) proposed a Thyroid Imaging Reporting and Data System (TI-RADS) for thyroid nodules based on ultrasonographic features. 4b - Suspicious nodules (10-50% risk of malignancy) Score of 2. Kwak JY, Han KH, Yoon JH et-al. 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. Accessed Nov. 4, 2019. Finally, someone has come up with a guide to assist us GPs navigate this difficult but common condition. 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). What is TIRADS 3 nodule? If nothing else, it might be worth the peace of mind to consult an oncology endo for a 2nd opinion. Doctors use radioactive iodine to treat hyperthyroidism. A prospective validation study that determines the true performance of TIRADS in the real-world is needed. 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]. A single copy of these materials may be reprinted for noncommercial personal use only. Symptoms and Causes Diagnosis and Tests Management and Treatment Prevention Outlook / Prognosis Living With Frequently Asked Questions Overview Dry skin. 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. The ACR-TIRADS guidelines also provide easy-to-follow management recommendations that have understandably generated momentum. Whether its benign or not, a bothersome thyroid nodule can often be successfully managed. TIRADS Management Guidelines in the Investigation of Thyroid Nodules; Illustrating the Concerns, Costs, and Performance TIRADS Management Guidelines in the Investigation of Thyroid Nodules; Illustrating the Concerns, Costs, and Performance J Endocr Soc. in 2009 1. Check for errors and try again. Once your doctor detects a thyroid nodule, you're likely to be referred to a doctor trained in endocrine disorders (endocrinologist). To illustrate the effect of the size cutoffs we have given 2 examples, 1 where the size cutoffs are not discriminatory and the cancer rate is the same above and below the size cutoff, and the second example where the cancer risk of the nodule doubles once the size goes above the cutoff. ACR TIRADS performed poorly when applied across all 5 TR categories, with specificity lower than with random selection (63% vs 90%). The score for this nodule is 1-2 points. The authors stated that TI-RADS 4 and 5 nodules must be biopsied. These appear to share the same basic flaw as the ACR-TIRADS, in that the data sets of nodules used for their development is not likely to represent the population upon which it is intended for use, at least with regard to pretest probability of malignancy (eg, malignancy rate 12% for Korean TIRADS [26]; 18% and 31% for EU TIRADS categories 4 and 5 [27, 28]). Muscle weakness. The more FNAs done in the TR3 and TR4 groups, the more indeterminate FNAs and the more financial costs and unnecessary operations. 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. Many studies have not found a clear size/malignancy correlation, and where it has been found, the magnitude of the effect is modest. Castellana M, Castellana C, Treglia G, Giorgino F, Giovanella L, Russ G, Trimboli P. Oxford University Press is a department of the University of Oxford. Of note, we have not taken into account any of the benefits, costs, or harms associated with the proposed US follow-up of nodules, as recommended by ACR-TIRADS. A TI-RADS was first proposed by Horvath et al. Surgery. 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). Russ G, Bonnema SJ, Erdogan MF, Durante C, Ngu R, Leenhardt L. Middleton WD, Teefey SA, Reading CC, et al. There are a number of additional issues that should be taken into account when examining the ACR TIRADS data set and resultant management recommendations. Given the need to do more than 100 US scans to find 25 patients with just TR1 or TR2 nodules, this would result in at least 50 FNAs being done. 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). Park JY, Lee HJ, Jang HW, Kim HK, Yi JH, Lee W, Kim SH. 1. 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). 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). 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.

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. 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. Thyroid nodules are very common, especially in the U.S. A cancer diagnosis is always worrisome, but even if a nodule turns out to be thyroid cancer, you still have plenty of reasons to be hopeful. Suppose you go to your doctor for a check-up, and, as shes feeling your neck, she notices a bump. 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. TIRADS 4 nodule is moderately suspicious for malignancy based on ultrasound findings. Therefore, 60% of patients are in the middle groups (TR3 and TR4), where the US features are less discriminatory. 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. Trouble sleeping. This assumption is obviously not valid and favors TIRADS management guidelines, but we believe it is helpful for clarity and illustrative purposes. Therefore, taking results from this data set and assuming they would apply to the real-world population raises concerns.

The gender bias (92% female) and cancer prevalence (10%) of the data set suggests it may not accurately reflect the intended test population. In response, ACR committees were formed to accomplish three goals: License Information Accessed Oct. 31, 2019. 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. During this test, an isotope of radioactive iodine is injected into a vein in your arm. Your doctor may recommend a thyroid scan to help evaluate thyroid nodules. 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. Cibas ES, Ali SZ; NCI Thyroid FNA State of the Science Conference. Advertising revenue supports our not-for-profit mission. But even larger thyroid nodules are treatable, sometimes even without surgery. Understanding the risks and harms of management of incidental thyroid nodules: A review. Is it time to panic? 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]. Its simple: Most people treated with RFA are back to their normal activities the next day with no problems. 24;8 (10): e77927. 3. Both TI-RADS classifications can safely avert avoidable FNACs in a significant proportion of benign thyroid lesions. 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. 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.

Data Availability: All data generated or analyzed during this study are included in this published article or in the data repositories listed in References. The Thyroid Imaging Reporting and Data System (TI-RADS) of the American College of Radiology (ACR) was designed in 2017 with the intent to decrease biopsies of benign nodules and improve overall diagnostic accuracy. (2017) Radiology. 2 Hypothyroidism should be appropriately treated. In fact, experts estimate that about half of Americans will have one by the time theyre 60 years old. 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. 2018; doi:10.3322/caac.21447. Prospective evaluation of thyroid imaging reporting and data system on 4550 nodules with and without elastography. Make a donation. 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). to propose a simpler TI-RADS in 2011 2. Thyroid cancer is one of the most treatable kinds of cancer. If a benign thyroid nodule remains unchanged, you may never need treatment. 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. 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. 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. 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.

Thyroid cancer management: From a suspicious nodule to targeted therapy. These publications erroneously add weight to the belief that TIRADS is a proven and superior model for the investigation of thyroid nodules. The system is sometimes referred to as TI-RADS Kwak 6. The . 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. 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. First, 10% of FNA or histology results were excluded because of nondiagnostic findings [16]. 1. It is very difficult to know the true prevalence of important, clinically consequential thyroid cancers among patients presenting with thyroid nodules. 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. 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. TI-RADS categories Composition Cyst Spongiform Mixed cystic/solid Solid lesions Echogenicity Shape Margin Echogenic foci This paper has only examined the ACR TIRADS system, noting that other similar systems exist such as Korean TIRADS [14]and EU TIRADS [15]. To develop a medical test a typical process is to generate a hypothesis from which a prototype is produced. The challenge of appropriately balancing the risks of missing an important cancer versus the chance of causing harm and incurring significant costs from overinvestigation is major. Apr 29, 2021. If a biopsy shows that you have a noncancerous thyroid nodule, your doctor may suggest simply watching your condition. 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. I would think that TIRAD-5 would be a high risk factor. A radioactive iodine scan uses a radioactive form of iodine and a special camera to detect thyroid cancer cells in your body. Alternatively, if random FNAs are performed in 1 in 10 nodules, then 4.5 thyroid cancers (4-5 people per 100) will be missed. Even a benign growth on your thyroid gland can cause symptoms. However, a thyroid scan can't distinguish between cold nodules that are cancerous and those that aren't cancerous. Reston, VA 20191
In: Conn's Current Therapy 2019. However, today more limited surgery to remove only half of the thyroid may be appropriate for some cancerous nodules. 11th ed. 2 For those that also have 1 or more TR3, TR4, or TR5 nodules on their scan, they cannot have thyroid cancer ruled out by TIRADS because the possibility that their non-TR1/TR2 nodules may be cancerous is still unresolved. 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]. Thyroid nodules are a common finding, especially in iodine-deficient regions. Russ G, Royer B, Bigorgne C et-al. Shin JH, Baek JH, Chung J, et al. In 2013, Russ et al. 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. Summary Test Performance of Random Selection of 1 in 10 Nodules for FNA, Compared with ACR-TIRADS. No, say experts at Johns Hopkins Department of Otolaryngology and Head and Neck Surgery. All rights reserved. What is TIRADS 4 nodule? The cost-effective diagnosis or exclusion of consequential thyroid cancer is an everyday problem faced by all thyroid clinicians. 2009;94 (5): 1748-51. A newer alternative that the doctor can use to treat benign nodules in an office setting is called radiofrequency ablation (RFA). Ultrasound can help evaluate a thyroid nodule and determine the need for biopsy. 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. The vast majority more than 95% of thyroid nodules are benign (noncancerous). 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. Another clear limitation of this study is that we only examined the ACR TIRADS system. Using TIRADS as a rule-out cancer test would be the finding that a nodule is TR1 or TR2 and hence has a low risk of cancer, compared with being TR3-5. The ACR TIRADS management flowchart also does not take into account these clinical factors. We examined the data set upon which ACR-TIRADS was developed, and applied TR1 or TR2 as a rule-out test, TR5 as a rule-in test, or applied ACR-TIRADS across all nodule categories. Eur. Even a benign growth on your thyroid gland can cause symptoms. 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. We assessed a hypothetical clinical comparator where 1 in 10 nodules are randomly selected for fine needle aspiration (FNA), assuming a pretest probability of clinically important thyroid cancer of 5%.

Accessed Oct. 31, 2019. Thus, the absolute risk of missing important cancer goes from 4.5% to 2.5%, so NNS=100/2=50. Sometimes, your doctor detects a thyroid nodule when you have an imaging test, such as an ultrasound, CT or MRI scan, to evaluate another condition in your head or neck. The following article describes the initial iterations proposed by individual research groups, none of which gained widespread use. The implication is that US has enabled increased detection of thyroid cancers that are less clinically important [11-13]. 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.
