New anti-cancer drug sunitinib (Sutent) can cause high blood pressure in patients with kidney cancer
Sunitinib works by blocking the activity of vascular endothelial growth factor (VEGF). Besides sunitinib, other so-called VEGF inhibitors have been developed, including bevacizumab (Avastin). Although these drugs are promising in fighting several types of cancer, they are associated with side effects, including high blood pressure, bleeding, gastrointestinal perforation, wound-healing complications and clotting.
The finding echoes the results of a study published last month that found the drug increased blood pressure and the risk of heart failure among patients with stomach cancer.
For the study were used home blood pressure monitoring, with the results sent automatically by telephone to the hospital. They found an immediate and marked increase in blood pressure in 14 patients with kidney cancer who were treated with 50 milligrams of sunitinib a day for four weeks.
In a statement released in December , sunitinib's maker, Pfizer Inc., agreed that these heart risks do exist.
