[Renal cell carcinoma in children]

Area of Science:

• Pediatric Oncology
• Urologic Oncology

Background:

• Renal cell carcinoma (RCC) is uncommon in children, with distinct behaviors compared to adult presentations.
• Established treatment protocols for adult RCC, primarily surgical resection, may not directly translate to pediatric cases.
• The efficacy of chemotherapy and radiotherapy for metastatic pediatric RCC remains poorly defined.

Observation:

• A retrospective review of a single pediatric institution's experience over twenty years identified only three cases of pediatric RCC.
• Detailed clinical features and therapeutic strategies employed for these three pediatric patients are presented.
• The study highlights the importance of clinical suspicion for RCC in children over five with renal masses, differentiating it from Wilms' tumor.

Findings:

• Staging and complete surgical resection appear to be significant prognostic indicators in pediatric renal cell carcinoma.
• The limited data underscore the rarity of this malignancy in the pediatric population.
• Current treatment approaches for advanced or metastatic pediatric RCC require further investigation and standardization.

Implications:

• Multicenter collaboration is crucial for standardizing treatment protocols for advanced-stage pediatric RCC.
• Further research is needed to define the role of novel therapies, including allogeneic stem cell transplantation, in managing metastatic pediatric RCC.
• Improved diagnostic and therapeutic strategies are essential for optimizing outcomes in children diagnosed with renal cell carcinoma.
