Thyroid cancer, nodules found in the lungs, how to judge whether thyroid cancer has metastasized?

Thank you for your trust and invitation!

Thyroid cancer, found nodules in the lungs, this situation, I also encountered in the outpatient review. The patient was about 40 years old. One year after thyroid cancer surgery, he was reexamined in the hospital. He found multiple nodules in both lungs 1 month, with different sizes and diameters of about 1 cm, which was highly suspected to be metastatic tumors. It was found that thyroid cancer had pulmonary nodules. How to determine whether it is transferred from thyroid cancer?

Let's see if there are any symptoms of lung metastasis. Generally speaking, patients with thyroid cancer rarely have lung metastasis. Thyroid cancer with lung metastasis generally indicates that the tumor is advanced, suggesting that it may develop to advanced stage. But compared with other advanced tumors, the prognosis is better.

Thyroid-lung metastasis may have a series of symptoms: the thyroid mass is obviously enlarged, and the mass can be felt, and the lungs will also have corresponding symptoms, such as cough, expectoration, hemoptysis, dyspnea, chest tightness and shortness of breath, or dyspnea and unnatural speech.

Second, do relevant examinations 1, chest CT scan.

To judge whether thyroid cancer has lung metastasis, it is necessary to do chest CT scan to judge the situation of lung nodules. If CT shows that nodules are easy to metastasize, it is highly suspected that thyroid cancer is accompanied by lung metastasis.

2.SPECT iodine-13 1 whole body imaging

If iodine intake is found in lung lesions, thyroid-lung metastasis can be basically determined.

3、PET-CT

PET-CT is expensive, but it is not necessarily the most effective inspection method. PET-CT has a good effect on undifferentiated thyroid cancer, but the well-differentiated thyroid cancer with a focus less than 5mm is prone to false negative.

4. Puncture pathological examination

For nodules that are highly suspected of lung metastasis, we can do biopsy and then make pathological diagnosis to determine whether they belong to lung metastasis of thyroid cancer.

Thyroid cancer has lung metastasis. If it is papillary thyroid carcinoma, the prognosis may be relatively better. Iodine-13 1 or local radiotherapy can be considered to inhibit the spread of cancer cells, so that comprehensive treatment can prolong the survival time of patients and improve their quality of life.

You can tell by making sure that you have moved some movies. The hard part needs to be punctured.

Relax when you are sick, just look at the article I forwarded by Xiao Wenqing. It's nothing.

It is generally felt that the lung nodules can be seen by CT, followed by biopsy, and the thyroid cancer can be killed by iodine 13 1, including the metastatic site.
