In people with advanced kidney cancer, blood pressure appears to indicate how well their medication is working, with high blood pressure linked to longer survival, new research shows. The finding comes from a study of 544 people being treated with the drug sunitinib (Sutent) for advanced kidney cancer. The researchers found that those whose maximum systolic blood pressure reached 140 mmHg or higher survived nearly four times longer than those who had a lower maximum systolic blood pressure -- 30.5 months vs. 7.8 months.
