Hypertension in Childhood Cancer Survivors: Causes, Screening, and Management.

purpose of reviewSurvivors of childhood cancer and hematopoietic cell transplant are at risk for developing chronic health conditions, including hypertension. Studies have identified hypertension as an influential risk factor for late kidney dysfunction and cardiovascular disease in childhood cancer survivors. The overall risk of hypertension depends on the specific cancer treatment, from chemotherapy to surgery to radiation. In this report, we aim to review the main causes of hypertension in childhood cancer survivors, with a focus on newer therapies, as well as the current recommendations for screening and management of hypertension in this patient population. RECENT

findingsNovel targeted therapies and immunotherapies are being increasingly used in pediatric cancer treatment, with unclear impact on long-term health. Screening guidelines for hypertension in the survivor population have been issued by various childhood cancer cooperative groups based on best available evidence and expert opinion. Newer studies have focused on individual risk prediction, which may help improve the diagnosis and management of hypertension, particularly in higher-risk individuals. Despite the importance of hypertension as one of the few modifiable risk factors for cardiovascular and renal health, studies have yet to define optimal blood pressure targets, screening parameters, or management strategies in childhood cancer survivors. Additionally, further studies are needed to demonstrate improvement in outcomes following interventions for hypertension specifically in this patient population.
