The Efficacy of Drug-eluting Bead Transarterial Chemoembolization Loaded With Oxaliplatin for the Treatment of Stage III-IV Non-small-cell Lung Cancer

Rationale and objectives: To explore the safety and efficacy of drug-eluting bead transarterial chemoembolization (DEB-TACE) loaded with oxaliplatin for stage III-IV non-small-cell lung cancer (NSCLC).

Materials and methods: From October 2018 to May 2021, a total of 31 patients with stage III-IV NSCLC received DEB-TACE loaded with oxaliplatin. Demographic characteristics, adverse events (AEs), and treatment responses were collected. Overall survival (OS) and progression-free survival (PFS) were calculated using the Kaplan-Meier method.

Results: All 31 patients successfully received DEB-TACE loaded with oxaliplatin. No procedure-related severe adverse events occurred. Hemoptysis symptoms presented in 8 patients but disappeared within 1-3 days. After DEB-TACE for 1, 2, and 6 months, the objective response rate (ORR) was 42%, 35%, and 26%, while the disease control rate (DCR) was 90%, 84% and 61%, respectively. The median PFS was 7 months (range 1-31 months), and the PFS rates at 3, 6, and 12 months were 87%, 71% and 29%, respectively. The median OS was 11 months (range 1-31 months), with OS rates of 87%, 77%, and 39% at 3, 6, and 12 months, respectively.

Conclusion: Oxaliplatin-loaded DEB-TACE is a feasible, safe, and effective treatment for patients with advanced refractory non-small-cell lung cancer.
