Unnecessary thyroid hormone control and fetal genetic testing was avoided during the gestational period with monthly follow-up. If no mutation is found, another test is performed looking for micro-RNA (miRNA) markers. While I think this information can be useful, I’m definitely not at the point where I would recommend that my patients receive genetic testing to find out if they have a genetic marker for a thyroid condition. Each Test is a specific, orderable test from a particular laboratory, and is assigned a unique GTR accession number. Quite a few people have had that test done and had an ‘Aha’ moment, taken their results to their GP and been started on T3 – often as a trial as the Doctor is not usually au fait with the D102 – but it has worked. […], […] goiter. How did I handle this result? Return envelope provided. 1ml) in an EDTA tube ; Extracted DNA, min. 2. First, a VX Thyroid Gen panel which covers the main genes involved as above. Initial cytomolecular testing sought to identify specific gene mutations associated with thyroid cancer. It could be any number of things and this graphic is a good reminder of some of the things that can go wrong – namely: nutrient levels, high cortisol, inflammation and genetic variants: Note the genetic variants issue there. The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. Genetic testing of this thyroid nodule would only be beneficial in this circumstance if the surgeon and patient would propose a total thyroidectomy based upon this additional information (instead of just a thyroid lobectomy). Multiple peer-reviewed scientific studies have shown that the mutations and genetic rearrangements, assayed by miRInform Thyroid, correlate with malignant thyroid nodules²∙³. The production and control of thyroid hormones each depend on complex mechanisms inside the thyroid … molecular testing have enabled families of those with thyroid cancers to determine whether or not they may be at increased risk for developing thyroid cancer and Physical exam.Your doctor will examine your neck to feel for physical changes in your thyroid, such as thyroid nodules. When used together, these advanced tests are helpful in providing the most accurate information about the risk of an indeterminate thyroid nodule developing … Change ), You are commenting using your Google account. You can read a lot more about testing the thyroid on my Thyroid Factsheet here. Up next in part 4: Antibody test for Hashimoto’s, or skip to part 5: Thyroid surgery: right hemithyroidectomy (lobectomy), and part 6: Papillary thyroid cancer diagnosis: This is a bad news/good news diagnosis, […] Previously: I have been diagnosed with non-toxic, multinodular goiter. This study evaluated the analytical performance of the newly created Thy- roSeq v3 test. 1.) Although the presence of a mutation was strongly associated with cancer, the likelihood of identifying a mutation was low; therefore, the test had low sensitivity. One of the most common things I get asked about is thyroid issues. He has a long-standing basic and translational research interest in the genetic regulation of growth, invasion and spread of thyroid tumors of all types. I have been doing the DI02 Thyroid test for quite some time – this often shows why a person is not responding so well to thyroxine treatment: because they have a particular fault on the gene that controls the delivery of T3 to the brain, so they need T3 treatment with their T4. doi: 10.1530/ERC-17-0405. One of my nodules is suspicious for neoplasm, and Afirma genetic testing classifies it as suspicious, so my right lobe had been scheduled for surgery.

I have been diagnosed with nontoxic multinodular goiter after visually seeing thyroid nodules in the mirror and getting a thyroid ultrasound. The main goal was to help decide if my “suspicious for neoplasm” nodule was benign or not. They are called Veracyte (Afirma), Asuragen, and ThyroSeq. If that’s positive, we then do a full thyroid screen looking at all of the markers involved. This rise in incidence h… Even better, you can also add an adrenal test to this as the Thyroid Elite. I like this as it includes all the usual thyroid markers including the autoimmune antibodies as well as Reverse T3, serum and red cell folate, serum and active B12, plus ferritin, Vitamin D and an inflammation CRP check. In my previous post, I mentioned my pathologist prepared a second biopsy of my suspicious nodule – part of the biopsy was smeared on a slide and pathologists at Veracyte verify my pathologist’s suspicious finding, and the other part of the biopsy goes in a tube where they use genetic testing looking at specific gene sequences, then use those results to classify it into the three categories (benign, suspicious, or malignant). This innovative genetic report explains the role your genes play in influencing your thyroid health and includes insights for both protecting your thyroid health and improving thyroid function. Previously: I have been diagnosed with nontoxic multinodular goiter after visually seeing thyroid nodules in the mirror and getting a thyroid ultrasound. I would have just posted a screenshot/picture of my actual results, but what I have seems to have been faxed and/or photocopied, is quite pixelated, and quite difficult to read. At this point, I hadn’t done my antibody test for Hashimoto’s yet because of the negative pushback about it I had received at my first ENT appointment, but my ENT said I should get the test done. Genetic testing for indeterminate thyroid cytology: review and meta-analysis. What does a Suspicious result on the Afirma test mean? MTC refers to Medullary thyroid cancer. The first thing I do in that case, if the symptoms seem to fit and, importantly, the person’s instinct is that their thyroid is involved somehow – remember you know your body better than anybody else! Genetic Testing of Thyroid Nodules: Veracyte / Afirma, Asuragen, and … The whole point of the test is to prevent people from having unnecessary thyroid surgeries. Or, you can add the thyroid blood markers as the Thyroid Pro. These indeterminate nodules are … Your doctor can request that the sample of your cells taken with a fine needle aspiration (FNA) be tested with ThyGeNEXT ® and ThyraMIR ® oncogene panels, which are highly sophisticated tests that detect genetic abnormalities within your thyroid nodule. Is there a lack of the co-factors such as iodine or selenium to do the necessary conversions, what autoimmune antibodies are present yada, yada, yada. Are you a person who needs more of the co-factors for certain pathways to offset a possible weakness? benign – the chance of cancer is very low, and surgery is not necessary. More often than not, though, the result looks fine and off you pop, having been told your problem is not with your thyroid. (Seriously – my ENT scheduler is way on top of things!) ( Log Out /  Post was not sent - check your email addresses! Remember, just because you have a weakness or SNP on a gene, doesn’t mean you develop the problem, but sometimes you can see a clear reason why your thyroid is messing about or not responding to treatment, and that can be crucial information. This is pretty much what I expected since suspicious for Hurthle cell neoplasms frequently show up as suspicious on the Afirma test regardless of whether it is benign or not. Unfortunately, the final diagnosis of thyroid cancer is not obtained until after the thyroid nodule has been surgically removed. Well, they have not been able to classify it as benign, and it could be still be benign or malignant. Change ), You are commenting using your Facebook account. The good news is the company my pathologist uses that does the testing in the US (Veracyte which does the“AFIRMA GSC” test) has a very generous payment plan so people in most income brackets won’t end up paying the $4000 or whatever the actual fee is. 1-3 As further evidence of molecular testing’s ubiquity, … Change ), You are commenting using your Twitter account. (In this article, only 16% of Hurthle cell neoplasms were “benign” on the Afirma test, while a large majority of nodules were found to be benign after surgically removed). In one test, ThyroSeq® Classifier: Confidently rules out cancer and prevents unneeded surgeries in 61-67% of patients with indeterminate cytology nodules 2-8. ( Log Out /  Molecular testing is increasingly becoming the new standard of care in evaluating thyroid nodules for the presence of cancer. The miRInform Thyroid panel is a cutting edge molecular diagnostic tool utilizing DNA and RNA based markers. At this point, the only way of finding out if it is benign vs. cancer is to surgically remove it, usually the whole lobe containing the suspicious nodule is removed. We’re looking for how much of the active T3 there is, or are you converting your T4 into the inactive Reverse T3? Do you need a higher than normal dose of meds or boosters because your TSH signalling is not quite right? If you throw in a vitamin and mineral test to check the nutrients needed for thyroid function too, that would be a really comprehensive check. Genetic Test A study by V. Panicker et al ^Common variation in the DI02 gene predicts baseline psychological well-being and response to combination T4/T3 therapy in patients on thyroid hormone replacement _, also shows that ^…there is a small subgroup of patients on thyroid hormone Show abstract. In the meantime, I was also diagnosed with Hashimoto’s, which probably had been going on for […], […] step: Veracyte Afirma genetic testing results and do I have […]. We’re sure you’ll find it useful, but please use it wisely and always exercise common sense. Or, you can add the thyroid blood markers as the Thyroid Pro . Yes. Even benign Hurthle cells have undergone some genetic changes, which makes them frequently show up as“suspicious” on the Afirma test, even when the nodule ends up being benign. Thyroid Stimulating Hormone (TSH) related genes: The basic thyroid test most doctors run is the TSH (thyroid-stimulating hormone) level. In my case, it was still suspicious, so surgery was the best choice for me. Because in all honesty it’s not going to change my approach with regards to the natural treatment protocol I’m going to recommend. I was at first reluctant to do the genetic testing, because I have quite a high deductible and my insurance doesn’t pay out very much until I hit that high deductible, and I know these genetic tests are incredibly expensive (although, not as expensive as thyroid surgery!). It is our opinion only, based on several years of natural medicine practice and research. Minor note:  At this point, I am going to point out that my thyroid nodule was suspicious for Hurthle cell neoplasm – Hurthle cells are associated with Hashimoto’s thyroiditis, as well as benign and malignant nodules. So, with these new tests, you can now cover most of those thyroid disruptors, certainly the genetic info, all the usual thyroid markers, high cortisol, inflammation, lack of Vitamin D, folate and B12 – and have a home visit for the blood to be taken in with the price – I’d say that’s a good test! Genetic Testing of Thyroid Nodule Specimens Helps Determine Treatment Recent advances in the molecular testing of FNA specimens allows detection of cancer-specific mutations in 14 thyroid cancer-related genes, and 42 types of other known gene abnormalities in thyroid cancer. 1.) More therapies are under review in clinical trials or by the FDA for different therapies in thyroid cancer that … Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. malignant – The chance of cancer Or indeed, if someone is on thyroxine from the doctor, why are they not feeling any better? ( Log Out /  Thyroid Genetic Test Health Report. View. You can also leave me a virtual tip below. The company behind the test, Veracyte, already sells a unique genetic … is very high >99% malignancy, surgery is necessary. My pathologist recommend the genetic testing, and I went with that. very low, and surgery is not necessary. The hope is that this test … Please read our Terms & Conditions and Privacy Policy fully, thank you. After a time, people with that ‘all-is-OK’ diagnosis start wondering if they should look a bit deeper – and end up at my or another functional medicine practitioner’s door. Thyroid hormones have a large range of crucial metabolic roles to play and can impact many different aspects of our health and well-being. ( Log Out /  suspicious – ~50% risk of cancer. I am very often asked: why do I have a problem with this or that to do with thyroid function? He or she may also ask about your risk factors, such as past exposure to radiation and a family history of thyroid tumors. BACKGROUND: Molecular tests have clinical utility for thyroid nodules with indeterminate fine-needle aspiration (FNA) cytology, although their performance requires further improvement. Not well. This is a topic I have wanted to cover in detail for a long time so when I read Dr. Wood’s paper and listened to him speak, I knew his expertise would be invaluable to this conversation. Here’s a pretty technical article for those of you who want to read more about it. Note: above is a screen shot from a sample Suspicious result from the Afirma website that I have edited to show my actual data. A person can be hypothyroid (underactive) or hyperthyroid (overactive). That includes six salivary cortisol measurements rather than the usual four, plus DHEA-s, testosterone and oestrogen. In this episode of Functional Medicine Research, I interview Dr. Tommy Wood on the question of whether commercial genetic testing for SNPs is helpful or harmful. A third test is ThyGeNEXT/ThyraMIR which uses a combination of two tests. Sample Requirements. The surgery scheduler scheduled my surgery for June 21, two months away. My nodules were biopsied on April 12, 2018, and one of them was suspicious for a neoplasm. However it can be a bit more complex than that and there has been a lot of new research on this over the past five years or so with quite a few other genes found to impact on thyroid function as well as D102. This is probably the most I have cried the entire time I was getting my thyroid diagnosed, because I didn’t really want surgery, but it clearly had to be done. My nodules were biopsied on April 12, 2018, and one of them was suspicious for a neoplasm, In this article, only 16% of Hurthle cell neoplasms were “benign” on the Afirma test, while a large majority of nodules were found to be benign after surgically removed, part 5: Thyroid surgery: right hemithyroidectomy (lobectomy), part 6: Papillary thyroid cancer diagnosis: This is a bad news/good news diagnosis, Thyroid diagnosis – Part 4: Hashimoto’s antibody test – Running with a thyroid problem, Part 5: Thyroid surgery: Pre-op, thyroid lobectomy surgery, and Post-op #1 appointment – Running with a thyroid problem, Thyroid diagnosis – Part 2: First ENT appointment and thyroid nodule biopsy – Running with a thyroid problem. Up to now, I have been checking the nutrients, cortisol and inflammation levels with thyroid people, but now it is time to add on the genetic info, which I think will be useful especially for people whose thyroid is not correcting with the usual treatment. You can do this Thyroid Gen test on its own, which is a simple cheek swab. If you put T3 with your T4 treatment, would it give your thyroid the boost it needs and stop side-effects? The approval of these targeted therapies in thyroid cancer suggests that physicians should be testing their patients for potential gene fusions or alterations. The gene panel investigates: You can do this Thyroid Gen test on its own, which is a simple cheek swab. Thank you, we all appreciate it. 3.) Thyroid hormone resistance Tolulope O Olateju 1 and Mark P J Vanderpump 2 Abstract Addresses 1Department of Endocrinology, Buckinghamshire Hospitals NHS Trust, Stoke Mandeville Hospital, Aylesbury, Bucks HP21 8AL, UK; 2Department of Endocrinology, Royal Free Hampstead NHS Trust, Pond Street, London NW3 2QG, UK Correspondence Dr Mark P J Vanderpump E-mail: … MicroRNAs are short single-stranded non-coding RNA segments and abnormal expression has been found in thyroid cancers. Tests and procedures used to diagnose thyroid cancer include: 1. Endocr Relat Cancer. Genetic biopsy: A Veracyte technician tests 142 genes from patients with suspicious nodules in their thyroid glands. All the tests come with a report telling you what issues your genes might suggest and what to do about them if you suspect they have been triggered. Imaging can pick up thyroid nodules that don’t cause symptoms and never would have been found by feeling the neck. The intended audience for the GTR is health care providers and researchers. My point is – after stressing out for multiple weeks, I talked myself into realizing there is a very high likelyhood my neoplasm would come back as “suspicious” (even if it was not cancer) and I was prepared for that. Genetic and molecular testing can also help doctors choose targeted therapies and design a treatment plan. A fine needle biopsy showed one of those nodules was suspicious for a neoplasm, and after an Afirma genetic test, it was still suspicious so we scheduled surgery. They each have their own strengths and weaknesses. Doing this helps me offer this free website and support to you and others. atypia of undetermined significance (AUS) or follicular lesion of underdetermined significance (FLUS), as Are you susceptible to high cortisol or inflammation which will impact it and need to do more to keep those dampened down? Epub 2017 Dec 18. 1 Molecular testing was developed in order to add more clarity to the diagnostic process, and is supported by trusted guidelines from the American Thyroid Association (ATA) and the National Comprehensive Cancer Network (NCCN).2,3 In these cases, your doctor may send the thyroid nodule cells for genetic testing. To do this, they use genetic testing (looking for specific gene mutations that are found in thyroid cancer) to put the nodule in one of three categories. I also had been putting off telling my out-of-town family members what was going on, and at this point had to explain to my brother and sister that there was a chance I had thyroid cancer (but that thyroid cancer is usually very treatable so they shouldn’t be too concerned about my prognosis). Thyroid Hormone Resistance via the THRB Gene. benign – the chance of cancer is [] Thus, you can be naturally higher or lower on TSH levels due to genetic variants. – is ask them to do a simple basal temperature test. A Gene Expression Classifier (GEC) test can drastically reduce unnecessary surgeries in thyroid nodule assessment, according to a new study. If I could have been classified as “benign”, I wouldn’t have needed surgery. Researchers think that much of this rise is due to the increased use of imaging procedures in the head and neck area to diagnose other conditions. I like this as it includes all the usual thyroid markers including the autoimmune antibodies as well as Reverse T3, serum and red cell folate, serum and active B12, plus ferritin, Vitamin D and an inflammation CRP check. I communicated with my ENT later that same day after seeing the suspicious result (and being relieved it did not say Malignant(>99% ROM)). Sorry, your blog cannot share posts by email. To do this, they use genetic testing (looking for specific gene mutations that are found in thyroid cancer) to put the nodule in one of three categories. Blood (min. Background: The accuracy of cancer detection in thyroid nodules by fine-needle aspiration (FNA) cytology and prognostication of thyroid cancer needs further improvement and can benefit from testing for molecular alterations known to occur in thyroid tumors. Genetic variants in the TSH related genes are responsible for approximately 50 – 90% of thyroid hormone variability. If you wish to share anything on your site, please do so but attribute it fully to me with a link back to this site, thank you. Genetic testing is available for certain types of cancer and can be used to confirm or rule out a diagnosis. I also had to explain to my parents everything that I have outlined about this test above, and how treatable thyroid cancer is. His primary research focus is the use of genetic and molecular techniques to improve the accuracy of diagnosis of thyroid nodules; more accurately predict outcomes in the disease; tailor targeted treatment to a patient’s unique needs; and guide the use of … Remember – the information given here is not meant to be a substitute for seeing a health professional. This methodology is now included in recommendations of leading clinical guidelines, including those from the American Thyroid Association (ATA), National Comprehensive Cancer Network and UpToDate. So far, so easy. The difficulties come in testing the thyroid because, as we know, the vast majority of mainstream doctors will test the TSH and T4 levels, including an autoimmune antibody if you are lucky. At this point, my choices were to wait and see and repeat the ultrasound/biopsy in 6 months, to have surgery to remove the thyroid lobe containing my suspicious for neoplasm nodule, or do genetic testing on the suspicious nodule and use those results to make a decision. If this test tells you that … 2.) The Veracyte/Afirma test has the ability to tell whether the FNA cytology is benign. You can see sample reports for each element here: thyroid gene, thyroid blood markers, adrenal markers. What I was not prepared for was finding out my “Suspicious” result when I got a call while shopping in Target from my ENT’s scheduler, trying to schedule my thyroid surgery. The Blueprint Genetics Hypothyroidism and Resistance to Thyroid Hormone Panel (test code EN0701): ICD codes Refer to the most current version of ICD-10-CM manual for a complete list of ICD-10 codes. The incidence of thyroid cancer has been rising steeply over the last few decades, though this rise appears to have tapered off in the last few years. The format is GTR00000001.1, with a leading prefix 'GTR' followed by 8 digits, a period, then 1 or more digits representing the version. The first test uses a mutation panel. To help, here is a rundown of the key genes that could be involved: So, I have listed several new tests here  to help with the genetic side of things. Now, there is an advanced diagnostic test to reduce that uncertainty and avoid unnecessary surgery. If I’ve helped, please use the links on the site – some of which are affiliates – and our trusted suppliers. If a result happens to show on that, happy days. Change ). Anyway, that was how I knew my test result was in. Accurately detects all types of thyroid cancer (papillary, follicular, Hürthle cell, medullary) and non-thyroidal lesions (parathyroid, metastases to the thyroid… Both the Thyroid Pro and Elite tests are blood tests and include a phlebotomy home visit in the price, which makes life nice and easy for a change! There are three commercially available genetic testing companies for thyroid nodules. The Afirma gene expression classifier (GEC) test uses thyroid cells obtained at the time of biopsy to screen for molecular markers (genes) that are associated with thyroid cancer. The truth of the matter is that is just not enough information to get a good look at what’s going on with the thyroid. Its manufacturers claim that that the test can predict which of the indeterminate nodules are likely to be benign (with a 95 % certainty), and therefore do not require surgery, from those that are likely cancerous (with a 50% certainty) and need to be referred to surgery.
