Is thyroid cancer cancer?

summary

Is thyroid cancer cancer? Thyroid cancer is the most common type of thyroid malignant tumor. Malignant lymphoma and metastasis are rare. Papillary thyroid cancer accounts for about 70% of thyroid malignant tumors; The cause of the disease is still unclear, which may be related to ionizing radiation and endocrine hormone disorder; The clinical manifestations were anterior cervical mass and lymphadenopathy. The main treatment was operation with good prognosis.

Is thyroid cancer cancer?

Malignant thyroid tumor is thyroid cancer, and pathological diagnosis is needed for specific classification. Malignant tumors from embryonic tissue are called "blastoma", such as nephroblastoma, neuroblastoma, retinoblastoma, etc. There are also some malignant tumors, such as leukemia, Hodgkin's disease, melanoma and so on. It can be seen that although there is no word "cancer" in the name of diagnosis of many diseases, it may also be a malignant tumor, which needs special treatment as soon as possible. We can't think that if there is no word "cancer" in the report, we can't take it lightly.

Thyroid is located in the human neck thyroid cartilage below, on both sides of the trachea, the shape of a butterfly, like a shield, so it is called thyroid. The thyroid gland is divided into left and right lobes and isthmus. The left and right lobes are located on the two sides of the lower part of the larynx and the upper part of the organ. The upper end is from the midpoint of thyroid cartilage, the lower end to the 6th tracheal cartilage ring, sometimes reaching the suprasternal fossa or retrosternal fossa.

The surgical treatment of thyroid cancer includes the operation of thyroid itself and neck lymph node dissection. At present, the scope of thyroidectomy is still different, and there is no basis for the results of prospective randomized controlled trials. However, complete tumor resection is very important. Meta analysis data suggest that complete tumor resection is an independent prognostic factor. Therefore, even for differentiated thyroid carcinoma, it is not appropriate to resect smaller than the glandular lobe. The resection of glandular lobe and isthmus is the smallest. Maximum to total thyroidectomy. The trend of thyroidectomy is more extensive. There is evidence that the recurrence rate is low after subtotal or total thyroidectomy. In the low-risk group, the recurrence rate 30 years after lobectomy was 14%, while in the total resection group, the recurrence rate was 4%. Generally, for the high-risk group, there was not much debate about the scope of the first operation. It was reported that the local recurrence rate after lobectomy was 26%, and the local recurrence rate after total resection was 10%. There was no difference between total thyroidectomy and near total thyroidectomy. The advantage of extensive surgery is to reduce the local recurrence rate. The main disadvantage is the increase of short-term or long-term complications after surgery. Lobectomy rarely leads to recurrent laryngeal nerve injury, and there is almost no serious hypoparathyroidism.

matters needing attention

Thyroid diseases, especially thyroid cancer, are on the rise, which should be paid more attention to. Thyroid surgery is prone to hoarseness, hypocalcemia and other surgical complications. The scope of surgical resection should be judged according to the patient's condition and medical and technical conditions. It should conform to the principle of tumor resection. At the same time, it should try its best to preserve nerve function and improve the quality of life of patients. To improve the surgical skills and strengthen the comprehensive treatment is the direction of improving the curative effect. For those with scar constitution and special cosmetic requirements, endoscopic thyroidectomy without scar is also feasible.
