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

Area of Science:

• Pediatric Oncology
• Cardiovascular Health
• Nephrology

Background:

• Survivors of childhood cancer and hematopoietic cell transplant are at increased risk for chronic health conditions, notably hypertension.
• Hypertension is a significant risk factor for late-onset kidney dysfunction and cardiovascular disease in this population.
• Cancer treatments, including chemotherapy, surgery, and radiation, influence the risk of developing hypertension.

Purpose of the Study:

• To review the primary causes of hypertension in childhood cancer survivors.
• To focus on the impact of newer cancer therapies on hypertension development.
• To outline current recommendations for screening and managing hypertension in pediatric cancer survivors.

Main Methods:

• Review of existing literature and guidelines from childhood cancer cooperative groups.
• Analysis of recent studies focusing on individual risk prediction for hypertension.
• Examination of the role of novel targeted therapies and immunotherapies.

Main Results:

• Novel therapies like targeted treatments and immunotherapies are increasingly used, but their long-term effects on health, including hypertension, are not fully understood.
• Screening guidelines for hypertension in survivors exist, based on expert opinion and available evidence.
• Individual risk prediction studies show promise for improving hypertension diagnosis and management, especially in high-risk individuals.

Conclusions:

• Hypertension is a critical modifiable risk factor for cardiovascular and renal health in childhood cancer survivors.
• Optimal blood pressure targets, screening parameters, and management strategies specifically for this population require further definition.
• Additional research is necessary to confirm the benefits of hypertension interventions on outcomes in childhood cancer survivors.
