Risk of Hypertension With Sorafenib Use in Patients With Cancer: A Meta-Analysis From 20,494 Patients.

Sorafenib is a new multikinase inhibitor; the incidence of hypertension (HTN) with sorafenib has been reported to vary substantially among clinical trials. We searched multiple databases to investigate the risk of sorafenib-induced HTN in patients with cancer. A total of 93 trials involving 20,494 patients were selected for this meta-analysis. The relative risks (RRs) of all-grade and high-grade HTN associated with sorafenib were 3.06 (P < 0.001) and 3.33 (P < 0.001). There are no significantly RRs of all-grade, 0.81 (P = 0.047), and high-grade HTN, 0.64 (P = 0.075), in sorafenib monotherapy versus other multitargeted antiangiogenic tyrosine kinase inhibitors. The incidence of sorafenib-associated all-grade and high-grade HTN was 21.3% (P < 0.001) and 5.9% (P < 0.001), respectively. The patients with renal cell carcinoma (RCC) and thyroid cancer have high incidence (≥20%) of sorafenib-associated all-grade HTN and high incidence (≥5%) of sorafenib-associated high-grade HTN. The trials with median treatment duration ≥ 4, 5, and 7 months were 21.0% (P < 0.001), 25.4% (P < 0.001), and 27.6% (P < 0.001); progression-free survival ≥ 6, 9, and 12 months were 24.5% (P < 0.001), 26.8% (P < 0.001), and 32.8% (P < 0.001); and overall survival ≥ 12, 18, and 24 months were 18.5% (P < 0.001), 22.5% (P < 0.001), and 25.9% (P < 0.001), respectively. There is a significantly high risk of sorafenib-induced HTN. In comparison between sorafenib and other multitargeted antiangiogenic tyrosine kinase inhibitors, RRs had no significance. The patients with RCC and thyroid cancer have significantly higher incidence of HTN. With prolonged treatment duration, progression-free survival, and overall survival, the incidence of all-grade HTN may increase.
