Zusammenfassung: | Background
Vascular endothelial growth factor (VEGF) inhibitors are known to cause hypertension. The purpose of this study was to assess the impact of blood pressure (BP) elevations on outcomes in patients receiving VEGF inhibitors.
Methods
This retrospective chart review analyzed patients receiving treatment with VEGF inhibitors. The primary endpoint was time to progression (TTP) in those with or without significant increase in BP (increase in systolic BP greater than 20 mm Hg or greater than 10 mm Hg increase in diastolic BP). Secondary endpoints included treatment interruption, therapy discontinuation due to documented adverse effect, and time to BP elevation. Subgroup analyses were completed in those receiving bevacizumab and oral tyrosine kinase inhibitors.
Results
A total of 155 patients were included and 93 patients (60%) experienced a significant increase in BP. Median time to development of an elevated BP was 47 days. Patients with significant increases in BP had a longer median TTP compared to patients without (8.1 months vs 4.4 months, p = 0.002). No differences were present between groups in treatment interruption or discontinuation due to a documented adverse effect and outcomes were similar in those receiving bevacizumab and oral tyrosine kinase inhibitors. In the analysis of the impact of severity of BP elevations, those with severe BP elevations were more likely to have treatment interrupted but discontinuation rates were similar across groups.
Conclusion
Development of significant BP elevations may be a marker of therapeutic response to VEGF inhibitors and does not limit treatment duration, even in those with severe elevations. |
