Is gefitinib effective?

Gefitinib (Gefitinib) is a targeted drug mainly used to treat some patients with non-small cell lung cancer (NSCLC), especially those carrying epidermal growth factor receptor (EGFR) mutations. Its effects vary from individual to individual, but in the right circumstances, gefitinib can show significant efficacy. For EGFR mutation-positive NSCLC patients, gefitinib can usually extend survival, reduce symptoms, and improve quality of life. Some studies have found that gefitinib can significantly improve patients' progression-free survival and even extend overall survival. However, gefitinib is not suitable for all patients with NSCLC, and its efficacy may vary depending on the type of EGFR mutation and other factors. There may also be some adverse reactions during treatment, such as skin rash, diarrhea, etc.
