Is chemotherapy necessary for advanced lung cancer?

1. Lung cancer, also known as primary bronchial carcinoma and primary bronchial lung cancer, is a common primary lung malignant tumor originating from the bronchial mucosa or glands. According to the tissue lesions, it can be divided into small cell carcinoma and non-small cell carcinoma. The clinical symptoms are mostly latent, mainly manifested as cough, sputum, hemoptysis, and weight loss.

2. If there is a gene mutation in advanced lung cancer, especially lung adenocarcinoma, oral targeted drug treatment is suitable. At this time, oral targeted drugs, such as erlotinib, gefitinib, dacomitinib, etc., are more effective than chemotherapy and have fewer side effects than chemotherapy. Therefore, chemotherapy can be temporarily skipped and oral targeted drugs can be directly selected.

3. If oral targeted drugs are resistant, you can consider replacing them with other targeted drugs such as crizotinib, alectinib, lorlatinib, or switching to chemotherapy.

4. If patients with advanced lung cancer do not have gene mutations, they are generally not suitable for oral targeted drug treatment, and chemotherapy is often the first choice. Through chemotherapy, some people can still control the growth of tumors and prolong the patient's life.
