[Organ-sparing surgery for nephroblastoma in children]

Area of Science:

• Pediatric Oncology
• Nephrology
• Clinical Surgery

Context:

• This study focuses on the treatment of nephroblastoma (Wilms tumor) in pediatric patients.
• It examines outcomes for 53 patients diagnosed with stage I-III disease in Belarus between 2005 and 2010.
• The treatment protocol included neoadjuvant chemotherapy, surgery (complete or partial nephrectomy), and adjuvant chemotherapy following the SIOP WT 2001 protocol.

Purpose:

• To evaluate the feasibility and outcomes of a treatment strategy involving prolonged adjuvant chemotherapy as a cytoreductive measure.
• To assess the impact of this approach on enabling organ-sparing surgery in pediatric nephroblastoma.
• To compare event-free survival rates between patients undergoing complete and partial nephrectomy.

Summary:

• Fifty-three pediatric patients with stage I-III nephroblastoma received neoadjuvant chemotherapy, surgery, and adjuvant chemotherapy (SIOP WT 2001 protocol).
• Prolonged adjuvant chemotherapy was utilized as a cytoreductive strategy to facilitate organ-sparing surgery in cases with a good clinical response.
• Five-year event-free survival rates were high and comparable: 91+/-6% for complete nephrectomy and 89+/-9% for partial nephrectomy (p=0.64).

Impact:

• The findings suggest that prolonged adjuvant chemoradiotherapy is a feasible and effective strategy for pediatric nephroblastoma patients with a good clinical response.
• This approach supports the possibility of organ-sparing surgery, potentially improving quality of life for young cancer survivors.
• The study highlights successful implementation of advanced treatment protocols in a specific regional healthcare setting.
