Renal involvement in children with malignancies.

Area of Science:

• Pediatric Oncology
• Nephrology
• Cancer Treatment Complications

Background:

• Children with malignancies experience renal issues from tumors, tumor lysis syndrome, and urinary tract obstruction.
• Therapeutic interventions like surgery, chemotherapy (cytostatics), and radiotherapy can cause renal side effects.
• Acute renal failure (e.g., cisplatin) and chronic dysfunction (e.g., ifosfamide) leading to growth failure are clinically observed.

Purpose of the Study:

• To summarize the causes and consequences of renal complications in pediatric cancer patients.
• To highlight the need for better understanding of the frequency and long-term impact of renal impairment.
• To emphasize the importance of long-term monitoring and future research directions.

Main Methods:

• Review of existing literature on renal complications in pediatric oncology.
• Analysis of reported frequencies of renal impairment and end-stage renal failure.
• Discussion of therapeutic agents and their nephrotoxic potentials.

Main Results:

• Renal complications stem from primary tumors, tumor lysis syndrome, and treatment modalities.
• While end-stage renal failure is rare (0.9% of renal replacement therapy patients), long-term sequelae are common.
• Nephrotoxic effects can be cumulative, necessitating vigilant follow-up.

Conclusions:

• Long-term monitoring of growth, blood pressure, and renal function is essential for pediatric cancer survivors.
• Further prospective research is needed to establish precise frequencies and prognosis of renal dysfunction.
• Data will inform risk-adapted treatment strategies and patient counseling regarding nephrotoxic therapies.
