| DNA shed from colon cancers into bloodstream successfully guides chemotherapy after surgery Posted: 04 Jun 2022 05:29 AM PDT A multi-institutional, international study found that testing for ctDNA after surgery and directing chemotherapy to ctDNA-positive patients reduced the use of chemotherapy overall without compromising recurrence-free survival. |
| Posted: 03 Jun 2022 06:49 AM PDT A new study has found that RAAS inhibitors, a class of blood pressure-lowering medicine, may be better at reducing the risk of brain aneurysm rupture. People with a brain aneurysm -- a weakened area of a blood vessel -- who were being treated for high blood pressure with medication from the class of drugs called RAAS inhibitors had a significantly lower risk of a ruptured aneurysm compared to those who took other blood pressure medications. These results indicate that RAAS inhibitors may be preferable to other blood pressure-lowering medications and could inform treatment decisions for people with high blood pressure who have unruptured intracranial aneurysms. |
