Patient case: 54-year-old female with non-small cell lung cancer; genetic feature: EGFR (D770N)

Clinical trial: Icotinib Combined With SBRT for Patients With Metastatic Non-squamous NSCLC With EGFR Mutation

Summary: Many patients with oncogene-driven non-small-cell lung cancer (NSCLC) treated with tyrosine kinase inhibitors experience limited sites of disease progression. For multiple metastases in patients with advanced NSCLC, increased local treatment may benefit to prolong patient survival. This study investigated the benefits of icotinib limited systemic disease progression and continuation of Stereotactic Body Radiation Therapy,in patients with metastatic EGFR-mutant NSCLC.

Detailed description: Lung cancer is the leading cause of cancer morbidity and mortality worldwide. The majority of lung cancer is nonsquamous NSCLC. EGFR tyrosine kinase inhibitors (EGFR-TKI) is a effective first-line treatment for EGFR mutations non-squamous NSCLC treatment.Icotinib is the first EGFR-TKI,and have been proved efficiently in the treatment of lung cancer, and SBRT become a main therapy for the primary lesion,Accordingly, we have come to a scientific hypothesis that icotinib combination with SBRT might be a better treatment strategy for stageIV non-squamous NSCLC patients with EGFR mutation. It can improve the PFS of stage ⅢB/Ⅳ non-squamous NSCLC patients with EGFR mutation . The primary endpoint is disease-free time to progression (PFS). The secondary study endpoint is objective response rate (ORR), disease control rate (DCR),overall survival(OS) safety and quality of life (QOL). Through this study lay the foundation for further exploration of the non-squamous NSCLC first-line treatment in patients with EGFR mutation strategy.
