- Abstract
Background: Antiangiogenic therapy is routinely used in a variety of cancer entities. Hypertension is the most common side effect of all currently available antiangiogenic treatments., Patients and Methods: In this prospective observational clinical trial, we investigated risk factors for blood pressure elevation in patients exposed to an antiangiogenic agent and explored the correlation between hypertension and the duration of antiangiogenic treatment., Results: In 169 patients, pre-existing antihypertensive medication was the most prominent risk factor associated with increased blood pressure during therapy. Between visits 1 and 3, the median systolic blood pressure increased by 10.85 mmHg in patients with pre-existing hypertension receiving antihypertensive medication while it increased by only 2.69 mmHg in patients without hypertension. The median increase in diastolic pressure was 7.28 versus 0.11 mmHg in patients with versus without pre-existing hypertension. Increases in blood pressure occurred early (within 6 weeks of starting therapy). In spite of this significant increase in the blood pressure, no major bleeding events or other related complications were observed during antiangiogenic therapy., Conclusions: Pre-existing hypertension and treatment with antihypertensive medication correlated with a more pronounced increase in blood pressure. Thus, intensified antihypertensive therapy might be warranted early during bevacizumab therapy in patients already receiving antihypertensive treatment.
