Abstrakt: Background: Tyrosine Kinase Inhibitors (TKIs) is an important therapy for patients with oncogene-mutated Non-Small Cell Lung Cancer (NSCLC). However, acquired resistance remains a major challenge. The efficacy of TKIs plus thoracic radiotherapy (RT) in oncogene-mutated NSCLC patients is uncertain. Therefore, we performed a meta-analysis to comprehensively evaluate the efficacy and safety of thoracic RT plus TKIs in oncogene-mutated NSCLC patients.
Methods: The following databases were searched for relevant studies: PubMed, EMBASE, and Cochrane Library. Studies comparing the efficacy and safety of TKIs plus RT with TKIs alone in oncogene-mutated NSCLC patients were included in this analysis. Outcomes were median progression-free survival (mPFS), median overall survival (mOS), and incidence of adverse events (AEs). This analysis performed a subgroup analysis of the efficacy of first-line TKIs in combination with RT.
Results: This meta-analysis included 12 studies with 2936 patients (n = 823 patients with TKIs plus thoracic RT, n = 2113 patients with TKIs alone). The results showed that patients who received treatment with TKIs plus thoracic RT were associated with superior mPFS and mOS than those who were treated with TKIs alone (hazard ratio [HR]: 0.42, 95% CI 0.30-0.59, p < 0.00001; HR: 0.56, 95% CI 0.41-0.70, p < 0.00001, respectively). Subgroup analyses showed that TKIs plus thoracic RT as first-line treatment was associated with better mPFS and OS (HR: 0.37, 95% CI 0.26-0.52, p < 0.00001; HR: 0.47, 95% CI 0.31-0.70, p = 0.0002, respectively). Although the combination of TKIs with thoracic RT was associated with an increased risk of total AEs (odds ratio [OR]: 1.17, 95% CI 1.06-1.29, P = 0.002), there was no significant difference in serious AEs (grade ≥ 3) (OR: 1.06, 95% CI 0.58-1.92, P = 0.86). The most frequently occurring radiation-related AEs were radiation pneumonitis, radiation esophagitis, and radiation dermatitis, with overall rates of 41.3%, 15.4%, and 11.1%, respectively. The incidence of severe radiation pneumonitis and radiation esophagitis was 4.5% and 6.2%, respectively.
Conclusions: In comparison to TKIs alone, TKIs plus thoracic RT are associated with survival benefits, especially as a first-line treatment option. Although TKIs plus thoracic RT may increase the risk of total AEs, it did not increase the risk of severe AEs. Therefore, TKIs plus thoracic RT may be a promising therapeutic regimen for oncogene-mutated NSCLC patients.
