Is radiotherapy effective for brain metastases from lung cancer?

Radiotherapy is highly effective for brain metastases from lung cancer and serves as a valuable treatment option for patients. 1. Radiotherapy can effectively alleviate symptoms caused by brain metastases of lung cancer, such as nausea, vomiting, and headache, with an efficacy rate reaching 70%-80%. 2. Radiotherapy improves local control in patients and reduces the growth of new lesions in the brain, thereby lowering mortality. 3. Radiotherapy can significantly relieve symptoms within a relatively short period (e.g., after 3–5 sessions or about one month), offering hope for long-term survival to patients with brain metastases from lung cancer. However, radiotherapy also has certain side effects, such as hematologic toxicity, gastrointestinal reactions, and brain edema. Close monitoring during treatment and appropriate measures are necessary to minimize their occurrence. Therefore, when choosing radiotherapy as a treatment method for brain metastases from lung cancer, patients should consult their doctors and develop an appropriate treatment plan based on their individual conditions.
