Welcome to our comprehensive guide on Hurthle cell carcinoma, a rare type of thyroid cancer. In this article, we will take a deep dive into all the important facts you need to know about Hurthle cell carcinoma. We will explore its causes, symptoms, diagnosis, treatment options, and prognosis, so you feel equipped to make informed decisions about your health. With only 3-5% of all thyroid cancers classified as Hurthle cell carcinoma, it’s crucial to understand the ins and outs of this disease. Let’s start with the basics and get a good understanding of what Hurthle cell carcinoma is.
What is Hurthle Cell Carcinoma?
Hurthle cell carcinoma is a rare form of thyroid cancer that originates from the follicular cells of the thyroid gland. This cancer accounts for only about 3-5% of all thyroid cancers and is also known as Hurthle cell neoplasm or Hurthle cell adenoma.
Hurthle Cell Carcinoma Causes
The exact cause of Hurthle cell carcinoma is unknown. However, it is believed to develop from mutations in the DNA of thyroid follicular cells. The mutations in these cells cause them to multiply rapidly and form a tumor. Scientists believe that environmental factors, such as exposure to radiation, may play a role in the development of Hurthle cell carcinoma, but more research is needed to confirm this.
Hurthle Cell Carcinoma Symptoms
Hurthle cell carcinoma may not present any symptoms in its early stages. However, as the cancer grows, patients may experience an enlarged thyroid gland, difficulty swallowing or breathing, hoarseness, and neck pain.
Hurthle Cell Carcinoma Diagnosis
Diagnosis of Hurthle cell carcinoma usually involves a physical examination of the thyroid gland, blood tests, imaging tests such as ultrasound, and a biopsy of the thyroid gland tissue.
The physical examination involves checking the thyroid gland for any lumps, swelling, or other abnormalities. Blood tests may be done to check for abnormal levels of thyroid hormone and to assess the overall health of the patient.
Imaging tests, such as ultrasound, may be used to get a better look at the thyroid gland and determine the size and location of any tumors. A biopsy of the thyroid gland tissue may also be done to confirm the presence of cancer cells and to determine the type of thyroid cancer present.
Fine-Needle Aspiration Biopsy
A fine-needle aspiration biopsy involves using a thin needle to extract a small sample of thyroid tissue for examination under a microscope. This procedure is typically done with the guidance of ultrasound, allowing the doctor to target a specific area of the thyroid gland.
If the biopsy confirms the presence of Hurthle cell carcinoma, further testing may be done to determine the stage and extent of the cancer.
It is important to note that some cases of Hurthle cell carcinoma may be misdiagnosed as benign Hurthle cell adenomas, which are noncancerous tumors that can also develop in the thyroid gland. In such cases, a repeat biopsy or surgery may be necessary to confirm the diagnosis.
Hurthle Cell Carcinoma Staging
Hurthle cell carcinoma is staged using the American Joint Committee on Cancer (AJCC) TNM staging system, which stands for tumor, node, and metastasis. This system categorizes the cancer based on the size and extent of the primary tumor, whether the cancer has spread to lymph nodes, and whether it has metastasized or spread to other organs or tissues.
The stages of Hurthle cell carcinoma are as follows:
| Stage | Description |
|---|---|
| T1 | The tumor is 2 centimeters or smaller and has not spread outside the thyroid gland. |
| T2 | The tumor is larger than 2 centimeters but has not spread outside the thyroid gland. |
| T3 | The tumor has spread outside the thyroid gland to nearby structures such as the larynx, trachea, esophagus, or nerve pathways. |
| T4a | The tumor has spread to the neck’s soft tissues, including muscles, blood vessels, or lymph nodes. |
| T4b | The tumor has spread to the tissues of the chest, including the trachea, esophagus, or major blood vessels. |
| N0 | No cancer cells are present in the nearby lymph nodes. |
| N1a | Cancer cells are present in the central compartment lymph nodes on the same side of the neck as the primary tumor. |
| N1b | Cancer cells are present in the lateral compartment lymph nodes on the same side of the neck as the primary tumor. |
| M0 | No metastasis or spread of the cancer to distant organs. |
| M1 | The cancer has spread to distant organs, such as the lungs or bones. |
The stages of Hurthle cell carcinoma help determine the appropriate treatment approach and predict the patient’s prognosis. Lower stages of the disease have a better prognosis than higher stages. Additionally, there is a higher risk of recurrence in patients with advanced stages of the disease.
Hurthle Cell Carcinoma Treatment Options
Treatment options for Hurthle cell carcinoma depend on the stage of the cancer and the patient’s overall health. The primary treatment for Hurthle cell carcinoma is surgery, and the goal of the procedure is to remove the cancerous thyroid tissue while preserving as much of the healthy thyroid tissue as possible.
In cases where there is remaining cancerous tissue after surgery, radioactive iodine therapy may be recommended. This treatment involves taking a pill that contains radioactive iodine, which is absorbed by the thyroid tissue and destroys any remaining cancer cells. External radiation therapy may also be used to shrink tumors before surgery or destroy remaining cancer cells after surgery. This treatment involves using high-energy radiation beams to target the cancerous thyroid tissue.
Chemotherapy may be recommended for advanced or metastatic Hurthle cell carcinoma. This treatment involves using drugs to kill cancer cells and is often used in combination with other treatments.
Hurthle Cell Carcinoma Surgery
Surgery is the primary treatment for Hurthle cell carcinoma. The goal of surgery is to remove the cancerous thyroid tissue while preserving as much of the healthy thyroid tissue as possible. The type of surgery performed depends on the stage and location of the cancer.
The most common surgical procedure for Hurthle cell carcinoma is a total thyroidectomy, which involves removing the entire thyroid gland. In select cases, a partial thyroidectomy may be performed to remove only the cancerous portion of the gland.
Before the surgery, patients will be given general anesthesia to put them to sleep. The surgery can be performed as an open surgery or as a minimally invasive procedure using a robotic approach. The surgeon will make an incision in the neck to access the thyroid gland and remove the cancerous tissue.
After surgery, patients will need to stay in the hospital for a few days to monitor their recovery. They may experience some discomfort and swelling in the neck area, which can be managed with pain medication and ice packs. Patients will also need to take thyroid hormone replacement medication for the rest of their life to regulate their body’s metabolism since the thyroid gland has been removed.
Radioactive Iodine Therapy for Hurthle Cell Carcinoma
Radioactive iodine therapy may be recommended for patients with Hurthle cell carcinoma after surgery to destroy any remaining cancerous tissue in the thyroid gland. It involves taking a pill that contains radioactive iodine, which is absorbed by the thyroid tissue and destroys any remaining cancer cells.
Before undergoing this treatment, patients must follow a low-iodine diet and avoid certain foods and medications that contain iodine. This is because the thyroid gland absorbs iodine, and a low-iodine diet can help make the therapy more effective.

Radioactive iodine therapy is generally well-tolerated by most patients and has a high success rate in treating Hurthle cell carcinoma. However, there may be some side effects associated with this treatment, such as fatigue and nausea. In rare cases, it may also cause damage to the salivary glands.
It’s important to discuss the potential risks and benefits of radioactive iodine therapy with your healthcare provider to determine if it’s the right treatment option for you.
Hurthle Cell Carcinoma Treatment Options
Treatment options for Hurthle cell carcinoma depend on the stage of the cancer, the patient’s overall health, and other factors. The primary treatment for Hurthle cell carcinoma is surgery, with additional treatments used as necessary to destroy any remaining cancerous tissue.
External Radiation Therapy for Hurthle Cell Carcinoma
External radiation therapy may be used to shrink Hurthle cell carcinoma tumors before surgery or to destroy any remaining cancer cells after surgery. This treatment uses high-energy radiation beams to target the cancerous thyroid tissue.
| Advantages | Disadvantages |
|---|---|
| Non-invasive | May cause fatigue and skin irritation |
| Effective in destroying cancer cells | May damage nearby healthy tissue |
| Usually only requires a few outpatient treatments | May cause long-term side effects such as a dry mouth or difficulty swallowing |
External radiation therapy is generally safe, and patients can typically return to normal activities shortly after treatment. However, it may cause side effects such as fatigue, hair loss, and skin irritation, and there is a small risk of development of secondary cancers in the radiation field. Patients should discuss the risks and benefits of external radiation therapy with their doctor.
