How a lung cancer medication works in real-world patient care in Spain

This is a real-world study that looks at how osimertinib, a targeted cancer medication, is actually used to treat patients with non-small cell lung cancer that has specific genetic changes. Researchers in Spain are collecting information from patient medical records to understand how well this treatment works, how long patients stay on it, and what side effects they experience in regular clinical practice—not in a controlled research setting.

Lung cancer is one of the most common and deadly cancers worldwide. While this medication has shown promise in clinical trials, researchers want to understand how it performs in real patients receiving treatment at hospitals and clinics, where conditions are messier and more varied than in controlled studies.
