ABSTRACT
Purpose@#We investigated the impact of four types of antihypertensive medications, angiotensinreceptor blockers (ARBs), beta blockers (BBs; both selective and non-selective), calciumchannel blockers (CCBs), and thiazide diuretics (TDs) on survival outcomes in epithelial ovariancancer (EOC). @*Materials and Methods@#A single-institutional retrospective chart review of 878 patients with EOC was performed.Survival was compared according to use of the four antihypertensive medications duringprimary treatment. Propensity score matching (ratio 1:3) was performed to control possibleassociated covariates, such as age, International Federation of Gynecology and Obstetricsstage, residual status after primary debulking surgery, and co-morbidity. @*Results@#Among 878 patients, 56 patients (6.4%) were ARB users, 62 (7.1%) were BB users, 107(12.2%) were CCBs users and 32 (3.6%) used TDs. Median progression-free survival (PFS)for ARB, BB, and CCB users was 37.8, 27.2, and 23.6 months compared with 33.6 monthsfor non-users. ARB was associated with 35% decreased risk of disease progression (hazardratio [HR], 0.65; 95% confidence interval [CI], 0.42 to 0.99; p=0.046) in multivariate analysis.After propensity score matching, median PFS for ARB users was 37.8 months and ARBuse remained to be associated with lower recurrence rate in univariate (p=0.035) and multivariateanalysis (HR, 0.60; 95% CI, 0.39 to 0.93; p=0.022). @*Conclusion@#In this study, ARBs use during primary treatment is associated with lower recurrence in EOCpatients. However, CCBs, BBs, and TDs did not show beneficial impact.
