Mediastinal lymph node metastasis of lung cancer?

summary

Metastasis of lung cancer is very common in clinic. Advanced lung cancer cells will spread to different organs. Metastasis of different organs can occur in advanced lung cancer, which can cause corresponding symptoms, often bring great pain to patients, and even threaten their lives. So mediastinal lymph node metastasis symptoms of lung cancer? Let's talk about it.

Mediastinal lymph node metastasis of lung cancer?

Local direct spread. This is mainly transmitted directly through cancer. After the occurrence of the cancer in the bronchial wall, it can grow into the bronchial lumen, resulting in stenosis or complete obstruction of the lumen. When the tumor grows out of the bronchus, it invades the lung tissue, then spreads and invades the adjacent organs and tissues. Central type lung cancer can compress or invade lymph, blood vessels, nerves and various organs and tissues in mediastinum after spreading into hilum and mediastinum. Tetrahedral lung cancer near the edge of the lung often invades the pleura, causing pleural effusion and chest wall metastasis. The cancer can also penetrate the interlobar fissure and invade other adjacent lobes. Huge cancer due to the central part of ischemia, tissue necrosis, liquefaction, the formation of cancerous cavity.

Hematogenous metastasis. The occurrence of this kind of metastasis indicates that the patients with lung cancer have reached the advanced stage, and it is an important means of lung cancer metastasis. Undifferentiated carcinoma may present early hematogenous metastasis. The blood metastasis of adenocarcinoma is more common. Hematogenous metastasis of advanced squamous cell carcinoma is not uncommon. The most common sites of metastasis are liver, bone, adrenal gland, kidney and brain.

Lymphatic metastasis. In cases of bronchial lung cancer, this kind of diffusion is often seen in cases. How to carry out lymphatic metastasis? Undifferentiated small cell carcinoma (NSCLC) can metastasize through lymph nodes at an early stage, and squamous cell carcinoma (SCC) is very common. Adenocarcinoma often metastasizes through blood, but lymphatic metastasis may also occur. Through the lymphatic ducts around the bronchi and pulmonary vessels, the cancer cells first invade the adjacent lung segments or lobes, and the parabronchial lymph nodes. Then, according to the location of the lung cancer, they reach the hilar, subcarina of trachea, mediastinum, paratracheal lymph nodes, and then the supraclavicular, anterior scalenus and cervical lymph nodes. Mediastinal paratracheal and cervical lymph node metastasis usually occurs on the same side of lung cancer, while left lung cancer lymph node metastasis can occur on the opposite side of lung cancer, which is called cross metastasis. After lung cancer invades the chest wall and diaphragm pleura, it can be transferred to axillary, cervical and epigastric lymph nodes through lymph nodes.

matters needing attention

Radiotherapy for advanced lung cancer is a more effective method. At present, the better way of radiotherapy is CyberKnife. CyberKnife has very small trauma in the treatment of advanced lung cancer. The most important thing is its good effect, which can effectively control the development of the disease. In the case of metastasis, CyberKnife can treat multiple tumors simultaneously.
