Thyroid imaging reporting and data system for US features of nodules: a step in establishing better stratification of cancer risk. Horvath E, Majlis S, Rossi R et-al. {"url":"/signup-modal-props.json?lang=us"}, Jha P, Weerakkody Y, Bell D, et al. The 2 examples provide a range of performance within which the real test performance is likely to be, with the second example likely to provide TIRADS with a more favorable test performance than in the real world. Is it time to panic? It is interesting to see the wealth of data used to support TIRADS as being an effective and validated tool. 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). Whilst we somewhat provocatively used random selection as a clinical comparator, we do not mean to suggest that clinicians work in this way. eCollection 2020 Apr 1. Radiology. Thyroid scan. 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. Elselvier; 2018. https://www.clinicalkey.com. Such validation data sets need to be unbiased. The implication is that US has enabled increased detection of thyroid cancers that are less clinically important [11-13]. These figures cannot be known for any population until a real-world validation study has been performed on that population.

Unfortunately, the collective enthusiasm for welcoming something that appears to provide certainty has perhaps led to important flaws in the development of the models being overlooked. Tests include: Physical exam. Explore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this condition. 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. 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. You're also likely to have another biopsy if the nodule grows larger. 3. Once your doctor detects a thyroid nodule, you're likely to be referred to a doctor trained in endocrine disorders (endocrinologist). If one assumes that in the real world, 25% of the patients have a TR1 or TR2 nodule, applying TIRADS changes the pretest 5% probability of cancer to a posttest risk of 1%, so the absolute risk reduction is 4%. A systematic autopsy study, The incidence of thyroid cancer by fine needle aspiration varies by age and gender, Thyroid cancer in the thyroid nodules evaluated by ultrasonography and fine-needle aspiration cytology, Comparison of 5-tiered and 6-tiered diagnostic systems for the reporting of thyroid cytopathology: a multi-institutional study. 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 proportion of malignancy in AUS and FLUS were . Thyroid nodules are common, very common. This paper has only examined the ACR TIRADS system, noting that other similar systems exist such as Korean TIRADS [14]and EU TIRADS [15]. The costs depend on the threshold for doing FNA. However, a thyroid scan can't distinguish between cold nodules that are cancerous and those that aren't cancerous. 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. 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). A robust validation study is required before the performance and cost-benefit outcomes of any of the TIRADS systems can be known. 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. 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. If it performs well enough, then the test is applied to a training set of data to better establish performance characteristics. 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. The system has fair interobserver agreement 4. For example, a previous meta-analysis of more than 25,000 FNAs showed 33% were in these groups [17]. Methodologically, the change in the ACR-TIRADS model should now undergo a new study using a new training data set (to avoid replicating any bias), before then undergoing a validation study. Surgery. Hong MJ, Na DG, Baek JH, Sung JY, Kim JH. All rights reserved. We have also estimated the likely costs associated with using the ACR TIRADS guidelines, though for simplicity have not included the costs of molecular testing for indeterminate nodules (which is not readily available in the New Zealand public health system) nor any US follow-up and associated costs. 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%. Fine-needle aspiration biopsy. 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]. Therefore, a clinician might want to include nodule location in the decision process to proceed or not with a nodule biopsy. Background Thyroid cancer diagnosis has evolved to include computer-aided diagnosis (CAD) approaches to overcome the limitations of human ultrasound feature assessment. You then lie on a table while a special camera produces an image of your thyroid on a computer screen. https://www.hormone.org/diseases-and-conditions/thyroid-nodules. K-TIRADS category was assigned to the thyroid nodules. ; Korean Society of Thyroid Radiology (KSThR) and Korean Society of Radiology. So just using ACR TIRADS as a rule-out test could be expected to leave 99% of undiagnosed cancers amongst the remaining 75% of the population, in whom the investigation and management remains unresolved. Russ G, Royer B, Bigorgne C et-al. Check for errors and try again. Accessed Oct. 31, 2019. 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. 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. A proposal for a thyroid imaging reporting and data system for ultrasound features of thyroid carcinoma. Full data including 95% confidence intervals are given elsewhere [25]. 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). Until a well-designed validation study is completed, the performance of TIRADS in the real world is unknown. 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. 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. JAMA Otolaryngology Head & Neck Surgery. 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. Thyroid nodules are very common, especially in the U.S. 2 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. Thyroid cancer management: From a suspicious nodule to targeted therapy. TIRADS 4 nodule is moderately suspicious for malignancy based on ultrasound findings. During this test, an isotope of radioactive iodine is injected into a vein in your arm. A negative result with a highly sensitive test is valuable for ruling out the disease. 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. Those wishing to continue down the investigative route could then have US, using TIRADS or ATA guidelines or other measures to offer some relative risk-stratification. Accessed Nov. 4, 2019.

So, for 100 scans, if FNA is done on all TR5 nodules, this will find one-half of the cancers and so will miss one-half of the cancers. 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]. Mayo Clinic is a not-for-profit organization. The score for this nodule is 4-6 points However, today more limited surgery to remove only half of the thyroid may be appropriate for some cancerous nodules. 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. 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). A pounding heart. This study aimed to evaluate the diagnostic performance of a CAD system in thyroid nodule differentiation using varied settings. 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. 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. 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]). This content does not have an Arabic version. I would think that TIRAD-5 would be a high risk factor. 2017; doi:10.1001/jamaoto.2017.0003. Accessed Oct. 31, 2019. The US follow-up is mainly recommended for the smaller TR3 and TR4 nodules, and the prevalence of thyroid cancer in these groups in a real-world population with overall cancer risk of 5% is low, likely<3%.

The . Eur. Both TI-RADS classifications can safely avert avoidable FNACs in a significant proportion of benign thyroid lesions. In some cases, nodules that take up less of the isotope called cold nodules are cancerous. 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. A newer alternative that the doctor can use to treat benign nodules in an office setting is called radiofrequency ablation (RFA). In: Ferri's Clinical Advisor 2020. He or she will also check for signs and symptoms of hypothyroidism, such as a slow heartbeat, dry skin and facial swelling. Choosing an experienced specialist can mean more options to help personalize your treatment and achieve better results. Russ G, Bonnema SJ, Erdogan MF, Durante C, Ngu R, Leenhardt L. Middleton WD, Teefey SA, Reading CC, et al. Elsevier; 2020. https://www.clinicalkey.com. Haugen BR, Alexander EK, Bible KC, et al. 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. A thyroid fine needle aspiration biopsy can collect samples of cells from the nodule, which, under a microscope, can provide your doctor with more information about the behavior of the nodule. 215-574-3150, 1100 Wayne Ave., Suite 1020 202-223-1670, 1892 Preston White Dr. 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. 703-390-9883, Looking for a Specific Department? Department of Endocrinology, Christchurch Hospital. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Ultrasonographic scoring systems such as the Thyroid Imaging Reporting and Data System (TIRADS) are helpful in differentiating between benign and malignant thyroid nodules by offering a risk stratification model. 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. 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. Memory problems. Those working in this field would gratefully welcome a diagnostic modality that can improve the current uncertainty. 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 score for this nodule is 3 points. Kitahara CM, et al. 3 However, they are found incidentally in up to 40% of patients who undergo ultrasonography of the neck, 4 and in 36% to 50% of persons at . Nodules that produce excess thyroid hormone called hot nodules show up on the scan because they take up more of the isotope than normal thyroid tissue does. PPV was poor (20%), NPV was no better than random selection, and accuracy was worse than random selection (65% vs 85%). People who undergo thyroid gland surgery may need to take thyroid hormone afterward to keep their body chemistry in balance. If a clinician does no tests and no FNAs, then he or she will miss all thyroid cancers (5 people per 100). The true test performance can only be established once the optimized test has been applied to 1 or more validation data sets and compared with the existing gold standard test. Silver Spring, MD 20910 Methods Ultrasound images of 205 thyroid nodules from 198 patients were analysed in this . Accessed Oct. 31, 2019. Therefore, compared with randomly selecting 1 in 10 nodules for FNA, using ACR TIRADS to correctly rule out thyroid cancer in 1 additional patient would require more than 100 US scans (NNS>100) to find 25 TR1 and TR2 patients, triggering at least 40 additional FNAs and resulting in approximately 6 additional unnecessary diagnostic hemithyroidectomies at significant economic and personal costs. Cytology result was Bethesda 6. In: Rosai and Ackerman's Surgical Pathology. This content does not have an English version. Make a donation. 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. Hormone Health Network. If one accepts that the pretest probability of a patient presenting with a thyroid nodule having an important thyroid cancer is 5%, then clinicians who tell every patient they see that they do not have important thyroid cancer will be correct 95% of the time. published a simplified TI-RADS that was prospectively validated 5. In rare cases, they're cancerous. There are inherent problems with studies addressing the issue such as selection bias at referral centers and not all nodules having fine needle aspiration (FNA). Refer to separate articles for the latest systems supported by various professional societies: A TI-RADS was first proposed by Horvath et al. The category definitions were similar to BI-RADS, based on the risk of malignancy depending on the presence of suspicious ultrasound features: The following features were considered suspicious: The study included only nodules 1 cm in greatest dimension. TI-RADS 2: Benign nodules. Feeling tired more easily. Metab. Cawood T, Mackay GR, Hunt PJ, OShea D, Skehan S, Ma Y. Russ G, Bigorgne C, Royer B, Rouxel A, Bienvenu-Perrard M. Yoon JH, Lee HS, Kim EK, Moon HJ, Kwak JY. Patients with left lobe thyroid gland tirads 3 or referred to as thyroid disease tirads 3 is a condition in which the left lobe of the thyroid gland has nodules. 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. The chance of finding a consequential thyroid cancer during follow-up is correspondingly low. Our thyroid experts in the head and neck endocrine surgery team diagnose and treat patients with a variety of thyroid and parathyroid conditions. It's most often used after surgery to find any cancer cells that might remain. In a clinical setting, this would typically be an unselected sample of the test population, for example a consecutive series of all patients with a thyroid nodule presenting to a clinic, ideally across multiple centers. American Thyroid Association. Routine FNA of this group is more likely to lead to false positive . Any use of this site constitutes your agreement to the Terms and Conditions and Privacy Policy linked below.

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]. 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].

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). Another clear limitation of this study is that we only examined the ACR TIRADS system. A radioactive iodine scan uses a radioactive form of iodine and a special camera to detect thyroid cancer cells in your body. Thyroid nodules even the occasional cancerous ones are treatable. The more important test metric for diagnosing a disease is the specificity, where a positive test helps rule-in the disease. Using TR5 as a rule-in test was similar to random selection (specificity 89% vs 90%). But even larger thyroid nodules are treatable, sometimes even without surgery. However, there are ethical issues with this, as well as the problem of overdiagnosis of small clinically inconsequential thyroid cancer. Thyroid nodules can be palpated in 4% to 7% of adults. Healthy thyroid cells absorb and use iodine from the blood. The test may cycle back between being used on training and validation data sets to allow for improvements and retesting. Thyroid nodules are detected by ultrasonography in up to 68% of healthy patients. 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. Hot nodules are almost always noncancerous.

An ultrasonogram reporting system for thyroid nodules stratifying cancer risk for clinical management. 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]). 2009;94 (5): 1748-51. 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. J. Clin.
