Nephron-sparing surgery (NSS) can preserve kidney function in children with synchronous bilateral Wilms tumor (BWT). Outcomes are generally good with proper patient selection and treatment, highlighting NSS as a viable option for BWT.
Area of Science:
- Pediatric Oncology
- Nephrology
- Surgical Oncology
Background:
- Synchronous bilateral Wilms tumor (BWT) affects about 5% of children with Wilms tumor.
- BWT is linked to a higher risk of renal insufficiency.
- Nephron-sparing surgery (NSS) aims to preserve renal mass and function.
Purpose of the Study:
- To review the use of NSS in pediatric patients with BWT.
- To discuss oncologic and functional outcomes of NSS for BWT.
- To highlight key considerations for NSS in BWT management.
Main Methods:
- Literature review of published outcomes for NSS in BWT.
- Analysis of factors contributing to successful NSS outcomes.
- Discussion of patient selection and therapeutic strategies.
Main Results:
- Published oncologic outcomes for NSS in BWT are generally favorable.
- Functional outcomes demonstrate improved renal function with NSS.
- Successful outcomes are attributed to careful patient selection and surgical technique.
Conclusions:
- NSS is an effective approach for managing BWT.
- Preservation of renal function is a key benefit of NSS in BWT.
- Optimal patient selection and adjuvant therapies are crucial for successful BWT treatment with NSS.
