non-small cell lung cancer Most are found in about 75-80% of all lung cancer patients. But it can be cured by surgery. But it must be detected only in the early stages. If left to spread in other stages, the chance of a cure will also decrease. For this type of lung cancer, it can be divided into three subtypes:
1. Type of adino carcinoma (Adenocarcinoma)
It is a type of cancer that can be found in the lung's mucous glands. The incidence of this type of cancer cells has continued to increase over the past 20 years. As medical diagnostic tools have evolved, the chances of detection are high. and is found in approximately 40% of all lung cancer patients. It is found in women and in people who have never smoked.
2. Square carcinoma type (Squamous carcinoma)
or epidermoid carcinoma, is a type of cancer that can be found in the bronchial epithelium. It is most common in males and the elderly, both male and female. Most patients are directly related to smoking. It begins in the large airway, resulting in frequent and severe coughing. They may even cough up blood or have pneumonia. This is because the cancerous lump has blocked the ducts of the trachea. The sputum is stuck inside, so it can't be coughed up to be excreted outside. These cells are a type of cancer that can be found in approximately 30-35% of all lung cancer cases.
3. Large cell type (Large cell carcinoma)
It is a type of cell that spreads quickly. It is found in the outer surface of the lungs. Most often it is around the edge. and due to the rapid distribution of cells Sometimes, the diagnosis and treatment cannot be done in a timely manner compared to the rapid growth of the disease. This type of cancer is found in approximately 5-15% of all lung cancer cases.
Small cell lung cancer (SCLC)
It is a type of cancer that is found in smokers or who have smoked before. It is found in approximately 15% of all lung cancer cases. This type of cell is characterized by a small and round shape. Sometimes called Oat cells, they originate from within the small trachea. then spread rapidly. If the treatment results are satisfactory Because it is a type of cell that responds well to chemotherapy and radiation.
Other types of lung cancer
– Carcinoid tumor cells are very rare, occurring in approximately 1-5% of all lung cancer patients.
Malignant mesothelioma is a type of cell that is caused by inhalation of asbestos or asbestos fibers. It is more common in the elderly. It is usually detected in the internal pleura and is extremely difficult to diagnose.
Guidelines for treating lung cancer
1. Treatment by surgery (surgery)
Treatment of all diseases through surgery Whether it is lung cancer, they all come together with risks. But the results of the surgical treatment will be satisfactory. If the patient's body is strong and has a good response. The chance of loss is also high.
for surgery to treat this lung cancer Doctors will do it in patients who are hopeful that all cancer cells can be removed. without damaging other parts of the lung until too much affected The remaining lungs must have enough room for breathing. Excision of lung cancer cells takes into account the size of the cut and the location of the cancer. including lung capacity that must be left Some lobes may be surgically removed, or the entire lobe is removed (lobectomy), or the entire lung may be removed. (pneumonectomy)
In addition, in some cases it may be necessary to remove the cancerous part at the same time. Especially if it's an open-chest surgery as well. If the doctor finds that the cancer has spread to other parts of the surrounding area, especially the membrane that separates the middle of the chest cavity. As for treatment, it's still a controversial process.
However, another treatment is The chest is closed without cutting the lungs and radiation is given to the patient after surgery. and another case is Lung resection or removal of the lobe of the lung along with the cancer found in the intercostal septum as much as possible After that, it will continue to be treated with radiation.
2. Treatment using radiation or radiation therapy.
Radiation therapy or radiation therapy is often used in inoperable patients. Including those who have undergone surgery but have not completely eliminated the cancer or the cancer may grow again. Properties from the use of radiation are good in that it can help relieve symptoms for patients, such as in the case of obstruction of the aorta. Patients with cerebral symptoms and bone pain, etc.
Currently, the main treatment for oat cell carcinoma is radiation therapy along with chemotherapy. Thus creating a channel for treatment with many new techniques, such as the technique of radiation therapy along with chemotherapy. 3D radiation , Fractionation , Radiation modifiers etc.
new treatment techniques It didn't just end there. Because there is also a new radiation technique that will increase the efficiency of treatment. It also reduces the likelihood of recurrence and can be used for palliative treatment as well.
