What are the ways in which laryngeal cancer spreads and metastasizes?

Laryngeal cancer is one of the common malignant tumors of the head and neck. The main clinical manifestations of laryngeal cancer are hoarseness, which is progressive, foreign body sensation in the throat, discomfort when swallowing, pain when swallowing, or accompanied by irritating cough, blood in sputum, and in severe cases, difficulty breathing and neck mass. Do you diagnose the spread and metastasis of laryngeal cancer? Experts say that laryngeal cancer can spread and metastasize in the following three ways according to its degree of differentiation and primary site:

① Direct spread: Advanced laryngeal cancer often spreads by infiltration to the submucosal membrane. Supraglottic cancer located in the epiglottis can invade the pre-epiglottic space, vallecula and tongue root forward. Arpygeal fold cancer spreads outward to the pyriform sinus and lateral wall of the hypopharynx. Glottic cancer can invade the anterior commissure forward and spread to the contralateral vocal cord; it can also destroy the thyroid cartilage forward, causing the laryngeal body to swell, and infiltrate the soft tissue of the anterior neck. Subglottic cancer spreads downward to the trachea, and can also penetrate the cricothyroid membrane to the anterior cervical muscle layer, develop to both sides, invade the thyroid gland; and affect the anterior wall of the esophagus backward.

② Lymphatic metastasis: The metastatic site is often seen in the lymph nodes at the bifurcation of the common carotid artery in the deep upper neck, and then develops along the internal jugular vein to the upper and lower lymph nodes. Subglottic cancer often metastasizes to the paraglottic lymph nodes.

③ Vascular metastasis: It can be transferred throughout the body through the blood circulation to the lungs, liver, kidneys, bones, pituitary gland, etc.

The above are the three ways of laryngeal cancer expansion and metastasis. According to analysis reports: the incidence of laryngeal cancer has an increasing trend. Regardless of gender, laryngeal cancer is most common in people aged 50-70. The incidence of laryngeal cancer is higher in cities than in rural areas, and in heavy industrial cities with heavy air pollution than in light industrial cities with light pollution. Therefore, experts remind everyone to pay attention to the daily living environment and develop a healthy lifestyle, which can play a certain role in preventing the occurrence of diseases.
