Vocal cord cancer symptoms?

summary

Vocal cord carcinoma is the most common type of laryngeal carcinoma. Most of them are well differentiated carcinoma, but they show infiltrative growth, even if the tumor surface morphology is regular. The growth characteristics of vocal cord carcinoma are determined by its unique anatomy. First of all, the lymphatic drainage of the true vocal cord is very rare except for posterior syndesmosis, so the early lesions rarely have metastasis; Secondly, the tumor on the surface of the vocal cord first diffuses through the elastic membrane in the larynx and invades the vocal cord muscle and the paravocal space, which is the last way for the tumor to pass through the cricothyroid space and get out of the larynx. Vocal cord cancer in the early onset of symptoms, because a slight change in the vocal cord surface can cause changes in sound. It is rare for patients with vocal cord cancer to see a doctor because of cervical lymph node enlargement, and lymph node metastasis occurs in advanced lesions. Vocal cord cancer symptoms? Let's talk about it

Vocal cord cancer symptoms?

The growth characteristics of vocal cord carcinoma are determined by its unique anatomy. First of all, the lymphatic drainage of the true vocal cord is very rare except for posterior syndesmosis, so the early lesions rarely have metastasis; Secondly, the tumor on the surface of the vocal cord first diffuses through the elastic membrane in the larynx and invades the vocal cord muscle and the paravocal space, which is the last way for the tumor to pass through the cricothyroid space and get out of the larynx. With the invasion of the deep tissue, the pathological changes were more serious,

There will be various degrees of movement damage, including subtle mucosal limitation and obvious vocal cord fixation. The degree of limitation of vocal cord movement is significantly related to local control rate and survival rate, which has been used in AJCC staging. The most unique anatomical structure of the vocal cord is the anterior commissure, which is directly connected to the inner surface of the thyroid cartilage plate, and can initially prevent the spread of tumor in the region. If the tumor passes through the ligament barrier of the anterior commissure, the cartilage will be involved. In this case, radiotherapy and surgery should be combined in the selection of treatment options [1,2].

Vocal cord cancer is symptomatic in the early stage of onset, because slight changes in the surface of vocal cords can cause voice changes. However, smokers often have hoarseness, and voice changes may not attract their attention. If the change of voice can not be relieved within a few years, laryngeal examination should be performed, such as indirect laryngoscope, fiber laryngoscope, dynamic laryngoscope, etc. It is rare for patients with vocal cord cancer to see a doctor because of cervical lymph node enlargement, and lymph node metastasis occurs in advanced lesions.

matters needing attention

Radiotherapy or partial laryngectomy can achieve good local control for early vocal cord cancer (T1 or T2). However, the curative effect of radiotherapy is better than that of surgery, and the pronunciation function remains good after radiotherapy. In most cases, the pronunciation is normal or close to normal; On the contrary, all patients with hemilaryngectomy or vocal cord resection had different degrees of hoarseness. Most of the patients with radiotherapy failure can be successfully rescued by hemilaryngectomy. Therefore, for the patients with the first choice of radiotherapy, even if the treatment fails, there are also rescue measures.
