Experts explain the spread and metastasis of late-stage laryngeal cancer

The spread and metastasis of late-stage laryngeal cancer is a major factor that makes it difficult to treat, and it is extremely harmful to the treatment and recovery of patients with late-stage laryngeal cancer . Here we will talk about the common spread and metastasis of late-stage laryngeal cancer.

Generally, the spread and metastasis of laryngeal cancer in the late stage mainly include:

1. Hematogenous metastasis

Hematogenous metastasis in the late stage of laryngeal cancer is not very common. It usually occurs in the late stage and is a manifestation of widespread metastasis throughout the body. Only a few patients in the early stage have metastasis to other parts of the body, internal organs or bones through the blood circulation. Among all patients with late stage laryngeal cancer, less than 5% have blood metastasis. Some people analyze the reasons for hematogenous metastasis and believe that it may be that the tumor directly erodes the blood vessel wall, allowing cancer cells to enter the blood circulation. Or it may be that it first invades the lymphatic vessels and then enters the veins and spreads with the blood.

2. Implant transfer

The larynx is located at the upper end of the respiratory system. Due to gravity and respiration, the shed cells of laryngeal cancer can fall into the bronchi or lungs with local secretions and cause implantation metastasis. Up to 73% of patients with advanced laryngeal cancer eventually develop lung metastasis, and 89% of low-secretion patients. However, lung metastasis can be either hematogenous metastasis or implantation metastasis of cell shedding. In addition, since both the larynx and lung cancer belong to the respiratory system and are stimulated by almost the same carcinogenic factors, it is difficult to exclude the possibility of a second primary lesion in the lungs when laryngeal cancer has already occurred.

The above is an introduction to the common spread and metastasis of late-stage laryngeal cancer. I hope it will be helpful to everyone. For more questions about late-stage laryngeal cancer, you can consult our online experts, who will answer them in detail.
