Hypertension is a frequent adverse event caused by vascular endothelial growth factor signaling pathway (VSP) inhibitors. However, the impact of hypertension on clinical outcomes during VSP inhibitor therapy remains controversial.Methods and Results: We reviewed 3,460 cancer patients treated with VSP inhibitors from the LIFE Study database, comprising Japanese claims data between 2016 and 2020. Patients were stratified into 3 groups based on the timing of hypertension onset: (1) new-onset hypertension (n=569; hypertension developing after VSP inhibitor administration); (2) pre-existing hypertension (n=1,790); and (3) no hypertension (n=1,101). Time to treatment failure (TTF) was used as the primary endpoint as a surrogate for clinical outcomes. The median (interquartile range) TTF in the new-onset and pre-existing hypertension groups was 301 (133-567) and 170 (72-358) days, respectively, compared with 146 (70-309) days in the non-hypertensive group (P<0.001 among all groups). In an adjusted Cox proportional hazard model, new-onset (hazard ratio [HR] 0.58; 95% confidence interval [CI] 0.50-0.68; P<0.001) and pre-existing (HR 0.85; 95% CI 0.73-0.98; P=0.026) hypertension were independent factors for prolonged TTF. The TTF of new-onset hypertension was longer than that of pre-existing hypertension (HR 0.68; 95% CI 0.62-0.76; P<0.001). This study highlighted that new-onset hypertension induced by VSP inhibitors was an independent factor for favorable clinical outcomes. Pre-existing hypertension before VSP inhibitor initiation was also a significant factor.
