Where is the main metastasis of laryngeal cancer?

summary

Laryngeal cancer should not be unfamiliar to people, and this situation may generally lead to physical problems of patients, but it is not clear about the spread and metastasis of laryngeal cancer after treatment. Now let me talk to you about the main metastasis of laryngeal cancer?.

Where is the main metastasis of laryngeal cancer?

First: direct diffusion: This is a common way of laryngeal cancer diffusion and metastasis. Advanced laryngeal cancer often infiltrates and spreads to submucosa. Supraglottic carcinoma of the epiglottis may invade the anterior epiglottic space, the valley of the epiglottis and the base of the tongue. The carcinoma of arytenoid epiglottic fold spread to pyriform fossa and lateral wall of laryngopharynx. Glottic carcinoma can invade anterior commissure and spread to contralateral vocal cord; It can also destroy the thyroid cartilage forward, make the laryngeal body expand and have soft tissue infiltration in front of the neck. Subglottic carcinoma extends down to the trachea, or through the cricothyroid membrane to the anterior cervical muscle layer, to both sides and to the thyroid gland; Posterior involvement of the anterior wall of the esophagus.

Second, lymph node metastasis: the metastatic sites were mainly located in the lymph nodes at the bifurcation of the common carotid artery in the deep superior group, and then developed along the internal jugular vein to the upper and lower lymph nodes. Subglottic carcinoma often metastasizes to Qi and paraglottic lymph nodes. This is also one of the ways of laryngeal cancer spread and metastasis.

Third: vascular metastasis: the spread and metastasis of laryngeal cancer also includes the systemic metastasis of laryngeal cancer to the lung, liver, kidney, bone, pituitary and other organs.

matters needing attention

You must do a good job in the life of laryngeal cancer care and prevention, once laryngeal cancer spread and metastasis, in the treatment will be more difficult, so once suffering from laryngeal cancer, found early symptoms, must go to the hospital in time for treatment, so as not to delay the disease.
