Symptoms of adenoid cystic carcinoma of trachea?

summary

Primary tracheal tumors are rare, accounting for 1% of all respiratory tract tumors, and malignant tumors account for 60% - 83%, which are more common than benign tumors. Adenoid cystic carcinoma was described by bill Roth (1865). It was named by Foote and frazell in 1953. It is also called "columnar adenoma" and belongs to malignant tumor of salivary gland. Adenoid cystic carcinoma of the trachea (TACC) accounts for about 30% of the total. Symptoms of adenoid cystic carcinoma of trachea? Let's talk about it

Symptoms of adenoid cystic carcinoma of trachea?

The main symptoms were wheezing and inspiratory dyspnea. When the tumor grows slowly into the lumen, because the ventilation capacity of the trachea is significantly greater than the general actual demand of the body, the small tumor in the trachea in the early stage will not cause any respiratory tract obstruction and cancerous appearance, only occasional chest tightness, irritating cough, expectoration or bloody sputum, and the symptoms are not typical.

In the middle and late stage, it is progressive dyspnea and wheezing, wheezing sound can be heard obviously, and part of it can see three concave inspiratory signs. A little more secretions will have the risk of asphyxia. Physical activity, body position change and tracheal secretions can aggravate the symptoms. Pain is a prominent symptom of adenoid cystic carcinoma, which may be related to the early invasion of nerve.

Early course of disease more irritating cough and sputum with blood, general hemoptysis is not much, sometimes stop. Therefore, most patients are easily misdiagnosed as general bronchial diseases. When the tumor invades adjacent organs, such as recurrent laryngeal nerve hoarseness, esophageal compression, dysphagia and so on. Others such as progressive weight loss, cachexia and other systemic nonspecific manifestations.

matters needing attention

TACC is also sensitive to radiotherapy, which can inhibit tumor growth and reduce the recurrence rate. The main indications of radiotherapy are: 1; ② Incomplete removal of the tumor margin; ③ Patients with poor general condition can not be operated. Because of the limitation of radiation dose, TACC can't cooperate or consolidate the curative effect repeatedly, so the interventional therapy of bronchoscopy is paid more and more attention.
