Perioperative Administration of an Intravenous Beta-Blocker Landiolol Hydrochloride in Patients with Lung Cancer: A Japanese Retrospective Exploratory Clinical Study

Beta-blockers have been reported to improve prognosis for various cancers, but the usefulness of perioperative administration remains unclear. To assess the efficacy of perioperative administration of landiolol hydrochloride, an intravenous beta-blocker, for lung cancer, we conducted a single-center, retrospective study. This study included patients who participated in a research conducted by Nippon Medical School Hospital from August 2012 to November 2013. The main selection criteria were males and females younger than 85 years old who have undergone anatomic lung resection for lung malignancies. Fifty-seven patients, 28 in the landiolol group and 29 in the control group, were included. The postoperative relapse-free survival rate at 2 years was 0.89 (95% CI, 0.78–1.01) in the landiolol group and 0.76 (95% CI, 0.60–0.91) in the control group (Chi-squared test; P = 0.1828). The relapse-free survival rate tended to be higher in the landiolol group than in the control. Hazard ratio for relapse-free survival in the landiolol group compared to the control was 0.41 (95% CI, 0.13–1.34), demonstrating that relapse free survival was prolonged in the landiolol group (log-rank test; P = 0.1294). It was suggested that relapse-free survival was prolonged when landiolol hydrochloride was administered from the induction to completion of anesthesia. Further studies are needed to confirm our findings.
