Can thyroid cancer spread mediastinum?
Metastases of the superior mediastinal lymph nodes have been found in up to 10% of patients with thyroid carcinoma (4,5). The metastatic lymphadenopathy usually arises from the cervical region and descends along the mediastinum, behind the great mediastinal vessels.
Where does thyroid cancer usually spread to first?
Most patients with thyroid cancer have the cancer contained in the thyroid at the time of diagnosis. About 30% will have metastatic cancer, with most having spread of the cancer to the lymph nodes in the neck and only 1-4% having spread of the cancer outside of the neck to other organs such as the lungs and bone.
What type of cancer is mediastinal mass?
In adults, most mediastinal tumors occur in the anterior (front) mediastinum and are generally malignant (cancerous) lymphomas or thymomas.

The thyroid gland is typically located in the lower third of the neck in front of the trachea (wind pipe) and above the breast bone. In some patients, the thyroid gland or masses within the gland can grow large and extend into the upper chest into a space known as the mediastinum.
What is mediastinal lymph nodes?
Mediastinal lymph nodes are glands that are located in the part of the chest that lies between the sternum and the spinal column. This region is referred to as the mediastinum, and contains the heart, thymus gland, windpipe, and large blood vessels.

- Pain or soreness in the front of the neck.
- A persistent cough.
- Trouble swallowing.
- Difficulty breathing.
How do doctors know if thyroid cancer has spread?
Taking a CT scan of the neck is done to help determine the location and size of possible thyroid cancer, and to assess whether thyroid cancer has invaded nearby structures. or spread to lymph nodes. Also, a CT scan may be used to look for the spread of cancer into distant organs such as the lungs.
What percentage of mediastinal masses are cancer?
When considering all age groups, nearly 55% of patients with benign mediastinal masses are asymptomatic at presentation, compared to only approximately 15% of those in whom masses are found to be malignant.
What is the survival rate of mediastinal cancer?
published a 41% survival in a 51.3-month follow-up in 27 patients with mediastinal NSGCT (11). The median survival for patients with mediastinal NSGCT in the present study was 13 months, with a 3-year cumulative survival rate of 26%.
How long does it take for thyroid cancer to spread to the lungs?
A total of 22% of patients had metastatic thyroid cancer to other places in the body in addition to the lungs. The average follow up was 8.5 years and 85% of the patients had progression of their disease. They used the average doubling time of the two largest lung nodules for the analysis.
Is thyroid cancer in the lungs curable?
Differentiated thyroid carcinoma (DTC), which includes papillary thyroid carcinoma (PTC) and follicular thyroid carcinoma (FTC), is one of the most curable endocrine cancers. Distant metastasis occurs in 4–23% of DTC patients and the lung is the most frequent site of distant metastasis (1–7).
What is mediastinal thyroid?
Mediastinal ectopic thyroid gland is a rare entity of the ectopic thyroid tissue (ETT) and accounts for approximately 1% of all mediastinal tumours [1]. Only a few cases have been reported in the literature.
Where is the thyroid located mediastinum?
The thyroid gland is typically located in the lower third of the neck in front of the trachea (wind pipe) and above the breast bone. In some patients, the thyroid gland or masses within the gland can grow large and extend into the upper chest into a space known as the mediastinum. This is known as a substernal thyroid.
What percentage of mediastinal masses are malignant?
Although relatively uncommon, the precise incidence of mediastinal masses remains unclear due to lack of ubiquity in classification and definition reported in medical literature. Most tend to be benign with approximately 25% found to be malignant.

- Swelling in the neck.
- Pain in the front of the neck, sometimes going up to the ears.
- Hoarseness or other voice changes that do not go away.
- Trouble swallowing.
- Trouble breathing.
