Abstract
Purpose: Acquired resistance has been an unignorable bottleneck for patients benefiting from epidermal growth factor receptortyrosine kinase inhibitor (EGFR-TKI). Ginsenoside Rg3 is an anti-angiogenic agent which can down-regulate expression of vascular endothelial growth factor (VEGF) and EGFR. Combination of EGFR-TKI and Ginsenoside Rg3 may be a promising strategy delaying acquired resistance. This retrospective study was to explore the efficacy and safety of this combined modality for EGFR-mutant nonsmall cell lung cancer (NSCLC) patients. Methods: The data of 124 patients with advanced NSCLC harboring EGFR active mutation were collected and analyzed. All of them were treated with first-line EGFR-TKI and were divided into two groups. In group A (n=52), patients were treated with EGFR-TKI plus ginsenoside Rg3. In group B (n=72), patients received EGFR-TKI alone. Progression-free survival (PFS), overall survival (OS), objective response rate (ORR) and side effects were analyzed to assess the applicability of EGFR-TKI plus ginsenoside Rg3. Results: By the deadline of March 15th, 2016, median PFS were significantly longer in group A than in group B (12.4 months vs. 9.9 months, P=0.017, HR 0.63, 95% CI, 0.43 to 0.92). In addition, ORR was higher in group A than in group B (59.6% vs. 41.7%, P=0.049). Median OS of group A showed a tendency longer than group B (25.7 months vs. 24.0 months, P=0.088, HR 0.64, 95% CI 0.39 to 1.07). Conclusions: Our data suggest that EGFR-mutant NSCLC patients can obtain median PFS benefit from EGFR-TKIs combining with ginsenoside Rg3,which provides a treatment option to delay acquired resistance of EGFR-TKI.
