Symptoms and signs of lymph node metastasis in laryngeal carcinoma
summary
First of all, we should be clear about the primary and secondary laryngeal cancer. Primary laryngeal carcinoma refers to the tumor located in the larynx, and squamous cell carcinoma is the most common. Secondary laryngeal cancer refers to the metastasis of malignant tumor from other parts to the larynx, which is rare. The main symptoms of laryngeal cancer were hoarseness, dyspnea, cough and dysphagia. The symptoms and signs of lymph node metastasis of laryngeal cancer, let me tell you.
Symptoms and signs of lymph node metastasis in laryngeal carcinoma
Direct diffusion is a common way of metastasis of laryngeal carcinoma. Advanced laryngeal carcinoma often infiltrates into 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.
Then there was lymph node metastasis. Most of the metastatic sites were 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.
Finally, the metastasis and spread of the last type of laryngeal carcinoma are introduced. That's vascular metastasis. The spread and metastasis of laryngeal carcinoma also include the systemic metastasis of laryngeal carcinoma to the lung, liver, kidney, bone, pituitary and other organs. The above is about the spread and metastasis of laryngeal cancer related knowledge, I hope you must do a good job in life care and prevention of laryngeal cancer.
matters needing attention
In histology and embryology, the left and right sides of the larynx develop independently. Supraglottic, glottic and subglottic primordia are derived from different primordia; The left and right lymphatic drainage are not connected with each other, and the supraglottic, glottic and subglottic lymphatic drainage are independent, which provides the basis for laryngeal surgery, especially partial laryngectomy. According to the location of the cancer, different surgical methods can be used. So even if got laryngeal cancer, also remember not to panic, according to the doctor's advice can be treated.
