Sintilimab plus Bronchial Arterial Infusion Chemotherapy/Drug-Eluting Embolic Chemoembolization for Advanced Non-Small Cell Lung Cancer: A Preliminary Study of 10 Patients.

To evaluate the short-term efficacy and safety of immunotherapy with sintilimab combined with bronchial arterial infusion (BAI) chemotherapy/drug-eluting embolic (DEE) bronchial arterial chemoembolization (BACE) for advanced non-small cell lung cancer (NSCLC). Ten patients with advanced NSCLC were treated with sintilimab plus BAI/DEE-BACE between December 2019 and November 2020 and retrospectively evaluated. The Response Evaluation Criteria in Solid Tumors version 1.1 was applied to evaluate the treatment response. The local tumor control duration, progression-free survival (PFS), and overall survival (OS) were estimated using the Kaplan-Meier analysis. At 30 days after the last multimodal treatment, complete response, partial response, and stable disease were recorded in 1 (10%), 7 (70%), and 2 (20%) patients, respectively, for an objective response rate of 80% and a disease control rate of 100%. No patient experienced progressive disease. The median duration of local tumor control was 8.0 months (95% CI, 6.2-9.7 months). The median PFS and OS were 11.0 months (95% CI, 6.9-15.1 months) and 8.0 months (95% CI, 5.5-10.5 months), respectively. Two cases of Grade III adverse events related to medications were reported. Sintilimab combined with BAI/DEE-BACE for patients with advanced NSCLC appears to be safe and feasible. Compared with previous studies on BAI/DEE-BACE, the addition of immunotherapy may improve survival.
