Abstrakt: Purpose: Primary pulmonary lympho-epithelioma-like carcinoma (PPLELC) is a rare subtype of primary non-small cell lung cancer (NSCLC). Currently, there is still lack of research data on anti-angiogenic therapy of advanced PPLELC. The purpose of this study was to investigate the efficacy and safety of anti-angiogenic therapy combined with chemotherapy compared with traditional chemotherapy for these patients. Methods: Advanced PPLELC patients admitted to six grade A hospitals from January 2013 to January 2021 were selected. The patients received anti-angiogenic therapy combined with chemotherapy (AT group) or chemotherapy (CT group) alone. Results: A total of 65 patients were included in this study, including 31 patients in the AT group treated with anti-angiogenic therapy combined with chemotherapy and 34 patients in the CT group treated with chemotherapy alone. As of October 1, 2021, the median progression-free survival (PFS) in the AT group was 11.2 months [95% confidence interval (CI), 5.9–16.5]. The median PFS in the CT group was 7.0 months [95%CI, 5.1–8.9] [Hazard Ratio (HR), 0.49; 95%CI, 0.29–0.83; P = 0.008]. The 1-year PFS rates were 41.9% and 17.6%, respectively. The overall response rates (ORR) of two groups were 45.2% (95% CI, 0.27–0.64), 38.2% (95% CI, 0.21–0.56), (P = 0.571). The disease control rates (DCR) of two groups were 93.5% (95% CI, 0.84–1.03), 88.2% (95% CI, 0.77–1.00), (P = 0.756). Conclusion: Among patients with advanced PPLELC, the PFS of patients with anti-angiogenic therapy combined with chemotherapy is better than that of patients with chemotherapy alone. Anti-angiogenic therapy combined with chemotherapy is an optional treatment scheme. [ABSTRACT FROM AUTHOR]
