• #1 Diagnosis and Treatment of Patients with Thyroid Cancer

  https://pmc.ncbi.nlm.nih.gov/articles/PMC4415174/

  Thyroid cancer is the most common malignancy of the endocrine system, representing 3.8% of all new cancer cases in the United States and is the ninth most common cancer overall. The American Cancer Society estimates that 62,450 people in the United States will be diagnosed with thyroid cancer in 2015, and 1950 deaths will result from the disease. […] To review the current approach to the diagnosis and treatment of patients with thyroid cancer. […] Over the past 3 decades, there has been a dramatic increase in the number of people diagnosed with thyroid cancer, which may be attributable to the wide use of imaging studies, including ultrasounds, computed tomography, magnetic resonance imaging, and positron emission tomography scans that incidentally detect thyroid nodules. […] The treatment options for patients with thyroid cancer include the surgical removal of the entire thyroid gland (total thyroidectomy), radioactive iodine therapy, and molecular-targeted therapies with tyrosine kinase inhibitors.

  The TNM (tumournodesmetastasis) staging system is often used for thyroid cancer. Each letter is assigned a number (and sometimes also a letter) to show how advanced the cancer is. […] Your doctor may also classify the cancer as low, intermediate or high risk. […] You may wish to discuss your prognosis and treatment options with your doctor, but it is not possible for any person to predict the exact course of the disease. […] The most common types of thyroid cancer (papillary and follicular) have an excellent long-term prognosis, especially if the cancer is found only in the thyroid or nearby lymph nodes in the neck. […] Even if the cancer has spread (metastasised), the outcome can still be good. […] Thyroid cancer has a very high five-year survival rate (97%).

• #3 Diagnosis and Treatment of Patients with Thyroid Cancer

  The prognosis and treatment of thyroid cancer depend on the tumor type and its stage at the time of diagnosis. […] Early diagnosis and appropriate treatment can improve prognosis and reduce mortality. […] The initial workup for any newly discovered thyroid nodule should include a serum thyroid-stimulating hormone (TSH) level. […] Nonfunctioning nodules will require the use of fine-needle aspiration (FNA) for cytologic evaluation. […] If the initial workup suggests a nonfunctional nodule with suspicious sonographic features, a FNA biopsy should be performed, because it remains the most accurate, cost-effective, and best diagnostic method for evaluating nodules. […] Thyroid cancer is diagnosed histologically via FNA biopsy and is categorized into 4 main types. […] After a diagnosis of thyroid cancer, it is important to perform preoperative staging and imaging, because it can alter the patient’s prognosis and treatment course.

• #4 Thyroid Cancer: Types, Symptoms, Causes & Treatment

  https://my.clevelandclinic.org/health/diseases/12210-thyroid-cancer

  Thyroid cancer starts in your thyroid, a small gland at the base of your neck, just above your trachea (windpipe). […] Thyroid cancer, a type of endocrine cancer, is generally highly treatable, with an excellent cure rate. […] Close to 53,000 Americans receive a thyroid cancer diagnosis every year. […] Treatments for most thyroid cancers are very successful. […] Healthcare providers use a staging system to determine if and how far thyroid cancer has spread. […] Thyroid cancer stages range from 1 (I) to 4 (IV). […] If you have an enlarged thyroid nodule or other signs of thyroid cancer, your healthcare provider may order one or more of these tests: […] During a fine-needle aspiration biopsy, your healthcare provider removes cells from your thyroid to test for cancer cells. […] This test can detect thyroid cancer and determine if the cancer has spread.

  https://www.mayoclinic.org/diseases-conditions/thyroid-cancer/symptoms-causes/syc-20354161

  Most often, diagnosing thyroid cancer starts with the physical exam. Your doctor will feel for physical changes in your neck and the thyroid. This usually is followed by blood tests and ultrasound imaging. Armed with this information, doctors may decide to do a biopsy to remove a small sample of tissue from your thyroid. In some cases, genetic testing may be done to help determine any associated hereditary causes. If diagnosed with thyroid cancer, several other tests may be done to help your doctor determine whether your cancer has spread beyond the thyroid and outside of the neck. These tests may include blood tests to check tumor markers and imaging tests, such as CT scans, MRI, or nuclear imaging tests, such as a radioiodine whole-body scan. […] Diagnosing thyroid cancer starts with the physical exam. Your doctor will feel for physical changes in your neck and the thyroid. This usually is followed by blood tests and ultrasound imaging.

  Usually, diagnosing thyroid cancer begins when a routine test suggests a problem with the thyroid. Your doctor will ask you about any symptoms you have and do a physical exam. Based on this information, your doctor may refer you to a specialist or order tests to check for cancer or other health problems. […] The following tests are commonly used to rule out or diagnose thyroid cancer. Many of the same tests used to diagnose cancer are used to find out the stage, which is how far the cancer has progressed. Your doctor may also order other tests to check your general health and to help plan your treatment. […] A physical exam allows your doctor to look for any signs of thyroid cancer. During a physical exam, your doctor may: feel the neck, thyroid and throat for any lumps, swelling or enlarged lymph nodes.

  A doctor will feel the thyroid gland for lumps and nodules. The neck and lymph nodes will also be examined for growth and swelling. […] Ultrasound is the most common method used to image the thyroid and lymph nodes and can be used to check suspected nodules for irregularities. However, ultrasound is not sensitive enough on its own to confirm a cancer diagnosis, which is why a fine-needle biopsy most often follows or is performed under the guidance of ultrasound. […] If a nodule on your thyroid is suspected to be cancerous, your doctor will perform a fine-needle biopsy by inserting a small needle into the and removing a sample of cells. These cells are sent to the lab and examined under microscope. Results can be benign, malignant or indeterminate. Indeterminate biopsies can be sent for additional molecular testing for risk assessment for cancer.

  https://www.thyroidcancer.com/thyroid-cancer/anaplastic/diagnosis

  The diagnosis of anaplastic thyroid cancer (also called anaplastic thyroid carcinoma) is usually associated with very worrisome symptoms. The diagnosis of anaplastic thyroid cancer is usually obtained with a fine needle aspiration biopsy. Most expert thyroid pathologists can make the diagnosis of anaplastic thyroid cancer with just the needle biopsy. […] In such circumstances, core biopsy may be required to produce the diagnosis of anaplastic thyroid cancer. Anaplastic thyroid cancer is one of the most lethal cancers of all mankind. […] If thyroid surgery can be performed, it is the most crucial issue pertaining to a patient with a diagnosis of anaplastic thyroid cancer. […] The diagnosis of anaplastic thyroid cancer is most commonly associated with a presenting symptom of a rapidly developing or growing neck mass.

  If your doctor suspects you have thyroid cancer, they will feel your neck to check for any swelling or lumps. If you have a thyroid lump, your doctor may then perform one or more of the following tests to confirm whether the lump is cancerous. […] While a blood test cannot diagnose thyroid cancer, it can check your levels of T3, T4 and thyroid-stimulating hormone (TSH). […] If your doctor suspects you may have medullary thyroid cancer, the levels of calcitonin in the blood may also be checked. High levels of calcitonin in the blood can be a sign of this type of thyroid cancer. […] The best way to get detailed information about your thyroid is with an ultrasound. This scan can show the size of any thyroid nodule and whether it is full of fluid or solid. […] It can also show whether a nodule has any features that suggest it may be a thyroid cancer rather than a benign nodule, and whether the lymph nodes in the neck appear to be affected.

  If your doctor thinks a biopsy is needed, the simplest way to find out if a thyroid nodule is cancer is with a fine needle aspiration (FNA). This type of biopsy can sometimes be done in your doctors office or clinic. […] Your doctor might order molecular tests to look for specific gene changes in the cancer cells. This might be done for a few different reasons: For diagnosis: If FNA biopsy results arent clear, the doctor might order lab tests on the samples to see if there are changes in the BRAF or RET/PTC genes. Finding one of these changes makes thyroid cancer much more likely. […] Blood tests can also be used to monitor certain thyroid cancers. […] To check the overall activity of your thyroid gland, your doctor might test the levels of thyroid-stimulating hormone (TSH or thyrotropin) in your blood. TSH is made by the pituitary gland. Your TSH level might be high if your thyroid isnt making enough hormones.

  Calcitonin: The C cells in the thyroid make calcitonin. Medullary thyroid cancer starts in the C cells. If you are at risk for medullary thyroid cancer, you may have your calcitonin level checked. It can also be measured after treatment for medullary thyroid cancer. Calcitonin may affect how calcium is made in the body. […] […] Not all thyroid cancer cells are alike. They may differ from one another based on what genes have mutations that are responsible for the growth of the cancer. Testing is performed to identify genetic mutations or the proteins they produce that drive the growth of the cancer. Once a genetic abnormality is identified, a specific targeted therapy can be designed to attack a specific mutation or other cancer-related change in the DNA programming of the cancer cells.

  The next step after thyroid cancer is diagnosed is to obtain a comprehensive, high-resolution ultrasound. This is important because papillary thyroid cancer and other types of thyroid cancer commonly spread to lymph nodes in the neck. If these are positive for thyroid cancer, fortunately, the surgeon will do a comprehensive surgery to remove both the thyroid and the lymph nodes. […] Tests and procedures used to diagnose thyroid cancer include: […] Your health care team uses information from your tests and procedures to determine the extent of the cancer and assign it a stage. Your cancer’s stage tells your care team about your prognosis and helps them select the treatment that’s most likely to help you. […] Cancer stage is indicated with a number between 1 and 4. A lower number usually means the cancer is likely to respond to treatment, and it often means the cancer only involves the thyroid.

This is important to ensure that the initial surgery is appropriate for the stage. […] […] Positron emission tomography scanning is an advanced technique for imaging body tissues and organs. One characteristic of living tissue is the metabolism of sugar. Prior to a PET scan, a substance containing a type of sugar attached to a radioactive isotope (a molecule that emits radiation) is injected into the patients vein. The cancer cells take up the sugar and attached isotope, which emits positively charged, low energy radiation (positrons) that create the production of gamma rays that can be detected by the PET machine to produce a picture. If no gamma rays are detected in the scanned area, it is unlikely that the mass in question contains living cancer cells. […]

[…] If your doctor can’t tell whether the nodule or lymph node is cancerous, you may have more scans or surgery to remove thyroid tissue to test (partial thyroidectomy). This will usually confirm the diagnosis. […] Genetic tests look for changes (mutations) in the genes. These changes are in the tumour cells. They are not usually needed for thyroid cancer and aren’t covered by Medicare. […] To see if the cancer has spread from the thyroid to other parts of your body, some people may have a CT (computerised tomography) scan or a PET (positron emission tomography) scan. […] A CT scan uses x-rays and a computer to create a detailed picture of an area inside the body.

  The American College of Radiologists (ACR) uses a thyroid cancer diagnostic management system called the Thyroid Imaging Reporting and Data System (TI-RADS). […] Although FNA cytology can detect half of MTCs, additional imaging tests are necessary to accurately diagnose MTC. […] CT has limited role in characterizing intra-thyroidal lesions and is more commonly used to evaluate metastatic disease. […] MRI has superior soft tissue contrast and resolution can discriminate between benign and malignant nodules. […] PET/CT and PET/MRI are best suited for evaluation of de-differentiated to poorly differentiated thyroid neoplasms, with emerging studies suggesting PET/MRI possibly being superior to PET/CT for staging of thyroid cancer in initial or follow-up settings. […] As prevalence and incidence of thyroid cancer increases, accurate timely evaluation of thyroid nodules is needed to improve survival. Imaging is integral to patient diagnosis and follow-up in thyroid cancer, with ultrasound being the primary modality of choice for evaluation of thyroid lesions.

  Thyroid cancer starts in the thyroid gland, which is located in the front of the neck. The histologic types of thyroid cancer can be categorized into three groups based on their cellular origin and characteristics: cancer derived from the thyroid epithelium, which includes papillary and follicular carcinomas, most commonly differentiated; cancer from parafollicular (C) cells, called medullary carcinomas; and anaplastic carcinomas, the most undifferentiated type. Papillary microcarcinoma refer to papillary cancer smaller than 1 cm. […] The diagnostic workup of a thyroid nodule typically includes measurement of serum thyroid-stimulating hormone and diagnostic ultrasound of the thyroid and neck (i.e., cervical lymph nodes). Depending on the results of initial testing, additional laboratory testing and imaging may be conducted. Fine-needle aspiration (FNA), with or without ultrasound guidance, is the procedure of choice when evaluating thyroid nodules to obtain cytology. The American Thyroid Association (ATA) recommends FNA for nodules larger than 1 cm with intermediate or highly suspicious ultrasound features and for nodules larger than 1.5 cm with mildly suspicious ultrasound features.

ATA guidelines recommend that persons with nondiagnostic cytology have repeat FNA with ultrasound guidance. Depending on the ultrasound characteristics, persons with indeterminate results (i.e., AUS/FLUS) may undergo additional testing (e.g., molecular testing, repeat FNA) before diagnostic surgery is pursued. Persons with nodules with malignant or suspicious cytology features generally proceed to surgery. […] Surgery is the main form of treatment for thyroid cancer. The type of surgery depends largely on what proportion of the thyroid gland is involved. Surgical options include total thyroidectomy or partial thyroidectomy (the latter is also known as a lobectomy). A partial thyroidectomy may be sufficient as the initial treatment for low-risk differentiated thyroid cancer, and is recommended if surgery is chosen for low-risk papillary microcarcinoma restricted to one lobe of the thyroid. […] The ATA recommends consideration of prophylactic lymph node dissection for clinically advanced papillary thyroid cancer without known nodal involvement, but this recommendation is based on low-quality evidence.

  Papillary thyroid carcinoma (PTC) is the most common type of thyroid carcinoma, defined by a set of distinctive nuclear features, including: Change of nuclear size and shape: nuclear enlargement, elongation and overlapping. Chromatin characteristics: chromatin clearing, margination and glassy nuclei. Nuclear membrane irregularity: irregular nuclear contour, nuclear groove and nuclear pseudoinclusion. […] Diagnosis is based on nuclear features. Subtyping (i.e., variant) is based on a combination of architecture / pattern, cytologic features, size and encapsulation. BRAF V600E is the most frequent mutation, particularly in tall cell and classic variants. […] Diagnosis is typically rendered using preoperative fine needle aspiration cytology based on the presence of typical cytologic features. Molecular testing of cytologic aspirates may assist in preoperative diagnosis. Diagnosis in resection specimen is based primarily on nuclear features, including alteration of nuclear size and shape, chromatin pattern and nuclear membrane irregularity. Further subtyping (i.e., variant) is based on a combination of architecture (e.g., solid, classic, follicular and cribriform morular variant), cytologic features (e.g., oncocytic, tall cell, hobnail and columnar cell variant), size (e.g., microcarcinoma) and encapsulation / infiltration (e.g., encapsulated variant, encapsulated follicular variant and infiltrative follicular variant).

[…] Early diagnosis and appropriate treatment can improve prognosis and reduce mortality. […] The initial workup for any newly discovered thyroid nodule should include a serum thyroid-stimulating hormone (TSH) level. […] Nonfunctioning nodules will require the use of fine-needle aspiration (FNA) for cytologic evaluation. […] If the initial workup suggests a nonfunctional nodule with suspicious sonographic features, a FNA biopsy should be performed, because it remains the most accurate, cost-effective, and best diagnostic method for evaluating nodules. […] Thyroid cancer is diagnosed histologically via FNA biopsy and is categorized into 4 main types. […] After a diagnosis of thyroid cancer, it is important to perform preoperative staging and imaging, because it can alter the patient’s prognosis and treatment course.

  The most common diagnostic procedures for thyroid cancer include thyroid function blood tests, imaging tests, and a biopsy. […] The best treatment options for thyroid cancer depend on the type, stage, and individual factors. Surgery, radioactive iodine therapy, and hormone therapy are often used, either alone or in combination. […] There are multiple tests available for thyroid cancer diagnosis, and it is not possible to identify one test as the best one. Also, specialists will perform multiple tests before confirming the diagnosis of thyroid cancer, as relying on just one test may lead to a misdiagnosis. […] It is possible to treat thyroid cancer successfully, provided it is diagnosed and treated in the early stages. Based on the type, stage, and health status of the patient, thyroid cancer may be treated through some highly effective treatments like surgery, radioactive iodine therapy, hormone therapy, and other treatment approaches.

  The TNM (tumournodesmetastasis) staging system is often used for thyroid cancer. Each letter is assigned a number (and sometimes also a letter) to show how advanced the cancer is. […] Your doctor may also classify the cancer as low, intermediate or high risk. […] You may wish to discuss your prognosis and treatment options with your doctor, but it is not possible for any person to predict the exact course of the disease. […] The most common types of thyroid cancer (papillary and follicular) have an excellent long-term prognosis, especially if the cancer is found only in the thyroid or nearby lymph nodes in the neck. […] Even if the cancer has spread (metastasised), the outcome can still be good. […] Thyroid cancer has a very high five-year survival rate (97%).

• #72 Papillary Thyroid Cancer (PTC): Symptoms & Treatment

  https://my.clevelandclinic.org/health/diseases/23382-papillary-thyroid-cancer-ptc

  Treatments for papillary thyroid cancer depend on the tumor size and whether the cancer has spread (metastasized). […] Surgery is the most common treatment for PTC. Depending on the tumors size and location, your surgeon may remove part of your thyroid gland (lobectomy) or all of your gland (thyroidectomy). […] If you have a total thyroidectomy, you’ll need to take thyroid hormone replacement medication for the rest of your life. […] Overall, the prognosis of papillary thyroid cancer is excellent, especially if you’re younger than 40 at diagnosis and have a small tumor. PTC can often be treated successfully and is rarely fatal, even if it has spread to lymph nodes in your neck. […] The survival rate for papillary thyroid cancer is excellent. More than 90% of adults with PTC survive at least 10 to 20 years after treatment.

  The American College of Radiologists (ACR) uses a thyroid cancer diagnostic management system called the Thyroid Imaging Reporting and Data System (TI-RADS). […] Although FNA cytology can detect half of MTCs, additional imaging tests are necessary to accurately diagnose MTC. […] CT has limited role in characterizing intra-thyroidal lesions and is more commonly used to evaluate metastatic disease. […] MRI has superior soft tissue contrast and resolution can discriminate between benign and malignant nodules. […] PET/CT and PET/MRI are best suited for evaluation of de-differentiated to poorly differentiated thyroid neoplasms, with emerging studies suggesting PET/MRI possibly being superior to PET/CT for staging of thyroid cancer in initial or follow-up settings. […] As prevalence and incidence of thyroid cancer increases, accurate timely evaluation of thyroid nodules is needed to improve survival. Imaging is integral to patient diagnosis and follow-up in thyroid cancer, with ultrasound being the primary modality of choice for evaluation of thyroid lesions.
