Questions about Lung Cancer
How is EGFR-mutant lung cancer treated when it causes leptomeningeal metastasis?
For EGFR-mutant lung cancer that has spread to the lining of the brain (leptomeningeal metastasis), studies point to osimertinib, sometimes combined with bevacizumab, and pemetrexed as treatments linked to longer survival.
Full answer →How well does osimertinib work for lung cancer patients who have active brain metastasis?
Osimertinib is effective for EGFR-mutated NSCLC patients with active brain metastases, with real-world data showing median progression-free survival of 12.4 months and intracranial responses, though resistance can develop.
Full answer →Which method is best for placing fiducial markers before radiation for lung cancer?
Endobronchial access has the lowest inaccurate placement rate and low complication risk, making it a strong choice for fiducial marker insertion before lung cancer radiation.
Full answer →Can a high neutrophil-to-lymphocyte ratio predict if lung cancer will spread to the brain?
Yes, a high neutrophil-to-lymphocyte ratio (NLR) is an independent risk factor for brain metastasis in lung cancer, according to a meta-analysis of 14 studies.
Full answer →What are the risks of brain metastasis in patients diagnosed with lung cancer?
Brain metastases are common in lung cancer, especially small cell (15% at diagnosis) and non-small cell types, with elevated neutrophil-to-lymphocyte ratio as a risk factor; targeted therapies like osimertinib show high intracranial response rates.
