How long is the survival period of small cell lung cancer? This is a question that many patients and their families are concerned about. It is difficult to answer this question because there are many factors related to the length of survival of small cell lung cancer, the main factors are the treatment plan and the overall physical quality of the patient. The relationship between small cell lung cancer survival and treatment method Because small cell lung cancer spreads faster, most of the small cell lung cancer in late stage has nearly metastasized and is not suitable for surgical treatment. Clinically, small cell lung cancer mostly adopts radiotherapy combined with traditional Chinese medicine to treat small cell lung cancer. Small cell lung cancer is slightly more sensitive to radiotherapy, so radiotherapy is more commonly used in the treatment of small cell lung cancer. However, it only relieves the local symptoms of the primary foci or metastases, but because radiotherapy causes harm to the normal cells of human body, radiotherapy should be used with caution for patients with advanced small cell lung cancer who are very weak. The most commonly used chemotherapy regimen for advanced small cell lung cancer patients is platinum regimen, in addition, paclitaxel, norethindrone, gemcitabine and other drugs are also widely used in the treatment of advanced small cell lung cancer. However, as the duration of chemotherapy increases, their therapeutic toxicity also increases gradually, so the choice of chemotherapy drugs and chemotherapy duration should be based on the remission of malignant tumor, symptom relief and treatment-related toxicity. The improvement of patients’ physical function is also one of the important factors to determine the survival period of small cell lung cancer in late stage. Therefore, it is extremely important for patients with advanced small cell lung cancer to improve their immune function and enhance their resistance to malignant tumors. In addition, in terms of diet, patients with advanced small cell lung cancer should eat more foods with immune enhancing and anti-small cell lung cancer effects, such as barley, yam, jujube, walnut, turtle, etc.; cough and phlegm should eat white fruit, radish, mustard, almond, orange peel, etc.; foods to reduce the side effects of radiotherapy and chemotherapy should be eaten: mushroom, cinnamon, etc. In general, the survival period of small cell lung cancer in late stage varies according to the treatment effect and physical function, as long as the appropriate treatment method is chosen, the symptoms can be improved and the survival period can be prolonged. With the continuous improvement of treatment methods, new treatments and drugs are increasingly used in the treatment of advanced small cell lung cancer, and the survival period of patients with advanced small cell lung cancer is significantly higher than before. The question of how long is the survival period of small cell lung cancer in late stage is not necessarily an exact answer for any patient, but it is most important to receive regular treatment as soon as possible.
