Aim: We conducted a systematic review and network meta-analysis to evaluate the efficacy of immunotherapy versus chemotherapy to treat extensive-stage small-cell lung cancer. Methods: We analyzed several eligible clinical trials using fixed or random-effects models to evaluate relative treatment effects depending on heterogeneity. Results: In the experimental group, immunotherapy showed significant improvement in overall survival (hazard ratio [HR]: 0.82; 95% CI: 0.74–0.89; I2 = 31.4%; p < 0.001) and progression-free survival (HR: 0.77; 95% CI: 0.80–0.83; I2 = 22.7%; p < 0.001). Conclusion: Immunotherapy is likely to significantly improve extensive-stage small-cell lung cancer patients' overall survival and progression-free survival compared with standard chemotherapy. Anti-PD L1 exhibited superior overall survival compared with anti-PD 1 and anti-CTLA4.

Aim: This study aimed to investigate the prognostic value of peripheral naive and memory CD8+ and CD4+ T cells and other immune cells in patients with oligometastatic non-small-cell lung cancer (NSCLC) undergoing radiotherapy (RT). Methods: A total of 142 patients with oligometastatic NSCLC treated with RT were enrolled, and their blood samples were collected within 3 days before RT. Immune cells were identified by flow cytometry. Results: Patients with high levels of naive CD8+ T cells had longer overall survival (p = 0.004) and progression-free survival (p = 0.001) than those with low levels of naive CD8+ T cells. Multivariate analyses revealed that naive CD8+ T cells were independently correlated with overall survival (p = 0.019) and progression-free survival (p = 0.024). Conclusion: The results suggest that peripheral naive CD8+ T cells may be an independent prognostic indicator for patients with oligometastatic NSCLC undergoing RT.
