Abstract

The present study aimed to evaluate the total progression-free survival (PFS) time of the 1st-line chemotherapy (CHT)/2nd‑line tyrosine kinase inhibitor (TKI) and 1st‑line TKI/2nd‑line CHT therapeutic regimens. Data from patients with non‑small‑cell lung cancer (NSCLC) harboring sensitizing epidermal growth factor receptor (EGFR) mutations, who had received both TKI and platinum CHT were retrieved from the Shandong Cancer Hospital (Jinan, China) database. A total of 89 patients were included, 50 of whom were treated with the 1st‑line CHT/2nd‑line TKI regimen and the remaining 39 patients underwent a 1st‑line TKI/2nd‑line CHT regimen. The differences in total PFS time between the two regimens were analyzed. The median total PFS time was 14.28 months with the 1st‑line CHT/2nd‑line TKI regimen and 17.77 months with the 1st‑line TKI/2nd‑line CHT regimen (adjusted hazard ratio, 0.96; 95% confidence interval (CI), 0.56‑1.66; P=0.886). A significant difference in PFS time was revealed between the two strategies when comparing only the 1st‑line or 2nd‑line treatments (all P<0.001). The objective response rate (RR) was 52.0% for those treated with 1st‑line CHT/2nd‑line TKI and 38.5% for the reverse regimen. After adjusting for associated factors, the odds ratio for the RR was 2.77 (95% CI: 0.77‑9.90; P=0.117). The current results revealed that there was no significant difference between the total PFS time of patients with NSCLC undergoing the 1st‑line CHT/2nd‑line TKI regimen compared with patients with NSCLC undergoing the 1st‑line TKI/2nd‑line CHT regimen.
