Abstract:

Objective

To analyze the clinical efficacy of CalliSpheres® drug-eluting beads bronchial arterial chemoembolization (DEB-BACE) in the treatment of stage Ⅲ~Ⅳ non-small cell lung cancer (NSCLC).

Methods

A retrospective analysis was conducted on 23 stage Ⅲ~Ⅳ NSCLC patients treated with DEB-BACE (observation group) and 23 patients treated with conventional BACE (C-BACE, control group) at our hospital from May 2019 to October 2024. Clinical efficacy and quality of life were compared between the two groups before and after treatment.

Results

After BACE treatment, partial response (PR) was observed in 18 cases and stable disease (SD) in 23 cases. The objective response rate (ORR) in the observation group 56.52% was higher than that in the control group 21.74% (P=0.016). No grade 3 or higher adverse reactions occurred during BACE treatment, while 23 cases (50.00%) experienced grade 1-2 adverse reactions. The adverse reactions of 7 cases(30.43%) in the observation group was lower than 16 cases(69.57%) in the control group (P<0.05). In the observation group, significant improvements were observed in physical function (Ftime=14.497), role function (Ftime=6.696), cognitive function (Ftime=4.839), and constipation symptoms (Ftime=22.000) after treatment (P<0.05). Additionally, quality of life (Fgroup=10.863), dyspnea (Fgroup=19.101), loss of appetite (Fgroup=9.134), and diarrhea (Fgroup=22.000) showed greater improvement in the observation group compared to the control group (P<0.05), with hemoptysis symptoms effectively controlled. During a median follow-up of 6.22 months (0.47~20.80 months), 31 patients (67.39%) survived and 15 (32.61%) died, including 5 deaths (21.75%) in the observation group and 10 deaths (43.48%) in the control group. Kaplan-Meier curves indicated no statistically significant difference in median overall survival between the two groups (P=0.181).

Conclusion

CalliSpheres® DEB-BACE demonstrates favorable safety and efficacy in treating stage Ⅲ~Ⅳ NSCLC, contributes to improved quality of life, and serves as a valuable alternative option for patients with stage Ⅲ~Ⅳ NSCLC.
