When to add anti-angiogenesis drugs to EGFR-mutated metastatic non–small cell lung cancer patients: A real-world study from Taiwan

The addition of anti-angiogenesis drugs to epidermal growth factor receptor (EGFR)–tyrosine kinase inhibitor (TKI) or chemotherapy in patients with EGFR-mutant non–small cell lung cancer (NSCLC) can improve disease control. We conducted a study to evaluate the efficacy of combination therapeutic strategies and identify patients who could benefit from combination therapy.
