Beware: Spread and metastasis of laryngeal cancer

Many people may be familiar with laryngeal cancer, but they are not very clear about the spread and metastasis of laryngeal cancer. So what exactly is the spread and metastasis of laryngeal cancer ? Let's talk about the spread and metastasis of laryngeal cancer.

Generally, laryngeal cancer can spread and metastasize in the following three ways depending on its degree of differentiation and primary site:

① Direct spread: This is a relatively common way of laryngeal cancer spread and metastasis. Late-stage laryngeal cancer often spreads to the submucosal infiltration. Supraglottic cancer located in the epiglottis can invade the pre-epiglottic space, vallecula and tongue root forward. Arytenoid fold cancer spreads outward to the pyriform sinus and the 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 anterior soft tissue of the 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 group, and then develops along the internal jugular vein to the upper and lower lymph nodes. Subglottic cancer often metastasizes to the paraglottic lymph node group. This is also one of the ways for laryngeal cancer to spread and metastasize.

③ Vascular metastasis: The spread and metastasis of laryngeal cancer also includes the metastasis of laryngeal cancer to the lungs, liver, kidneys, bones, pituitary gland, etc. through the blood circulation.

The above is an introduction to the spread and metastasis of laryngeal cancer. Once laryngeal cancer spreads and metastases, it will be more difficult to treat. Therefore, once you suffer from laryngeal cancer, you must go to the hospital for treatment in time and never delay.
