Efficacy Analysis of DSA-Guided Bronchial Arterial Chemoembolization Interventional Therapy in Patients with Middle-Advanced Primary Bronchial Lung Cancer.

ABSTRACT

Objective: To investigate the clinical efficacy of digital subtraction angiography- (DSA-) guided bronchial arterial chemoembolization (BACE) in patients with primary bronchial lung cancer. Methods: A total of 178 patients with primary intermediate and advanced bronchial lung cancer admitted to our hospital from February 2019 to March 2020 were selected as the subjects, and they were divided into control group (84 cases) and observation group (94 cases) according to the different chemotherapy regimens adopted by the patients. The control group was treated with traditional perfusion chemotherapy, and the observation group was treated with DSA-guided BACE interventional therapy, treated for 4 cycles, and followed up until the end of June 2021. The short-term clinical efficacy, hemoptysis remission, and incidence of adverse reactions were compared between the two groups. The mortality and recurrence rates between the two groups from treatment to the end of follow-up were counted, and the quality of life after treatment and 1 year after treatment were compared. Results: The short-term remission rate (73.40% vs. 58.33%), disease control rate (93.62% vs. 84.52%), hemoptysis remission rate (75.00% vs. 41.51%), the quality of life after chemotherapy cycle (90.86 ± 2.55 vs. 78.04 ± 2.21), and the quality of life after 1 year of follow-up (85.68 ± 2.23 vs. 70.27 ± 1.72) in the observation group were significantly higher than those in the control group, and the difference was statistically significant (P < 0.05). The incidence of adverse reactions (9.57% vs. 20.24%), mortality (10.64% vs. 21.43%), and recurrence rate (11.70% vs. 27.38%) during the follow-up period in the observation group were significantly lower than those in control group, and the differences were statistically significant (P < 0.05). Conclusion: DSA-guided BACE interventional therapy for patients with primary middle-advanced bronchial lung cancer has significant efficacy, which can not only reduce the mortality and recurrence rate of patients but also improve the quality of life of patients, with fewer adverse reactions and high safety, which is worthy of promotion.
