The purpose of this study is to evaluate the disease control rate (DCR) of gefitinib as third-line retreatment in stage IIIB/IV NSCLC with EGFR 19del/L858R positive mutation patients who had benefited from first-line gefitinib treatment with EGFR 19del/L858R positive mutation and tumor progression after the second-line chemotherapy

2. Male or female aged 18 years or older; 3. Subjects were diagnosed with stage IIIB or IV NSCLC before starting the first dose of gefitinib third-line treatment; 4. EGFR exon 19 deletion or exon 21 L858R substitution mutation confirmed; 5. ECOG performance status 0-2; 6. Life expectancy of at least 12 weeks or longer; 7. Has at least one measureable lesion by RECIST 1.1; 8. NSCLC of enrolled subjects previously progressed after first-line gefitinib treatment (PFS ≥ 6 months) and progressed again after second-line chemotherapy (not limited for chemotherapy regimen, ≥ 4 cycles of chemotherapy). --- L858R ---
Non Small Cell Lung Cancer Carcinoma, Non-Small-Cell Lung - Primary Study Objective: To evaluate the disease control rate (DCR) of gefitinib as third-line retreatment in stage IIIB/IV NSCLC with EGFR 19del/L858R positive mutation patients who had benefited from first-line gefitinib treatment with EGFR 19del/L858R positive mutation and tumor progression after the second-line chemotherapy - Secondary Study Objectives: To evaluate objective response rate (ORR), progressive-free survival (PFS), overall survival(OS) and quality of life (QoL) of gefitinib as third-line retreatment in NSCLC patients To evaluate the safety of gefitinib as third-line treatment in NSCLC patients - Exploratory analyses: To dynamically monitor EGFR mutation status and explore the relationship with clinical outcome --- L858R ---
