Summary
Nephron-sparing surgery (NSS) is effective and safe for low-stage renal cell carcinoma, offering a low recurrence risk. Further research is needed before widespread recommendation for this kidney cancer treatment.
Area of Science:
- Urology
- Oncology
- Surgical Oncology
Background:
- Renal cell carcinoma (RCC) is a common kidney cancer.
- Radical nephrectomy is the standard treatment for localized RCC.
- Nephron-sparing surgery (NSS) aims to preserve kidney function.
Purpose of the Study:
- To evaluate the effectiveness and safety of NSS for low-stage, accessible renal cell carcinoma.
- To compare NSS outcomes with radical nephrectomy, the established treatment.
- To assess the risk of local recurrence and impact on renal function.
Main Methods:
- A transperitoneal approach was used for tumor enucleation in 36 patients with small (< or = 5 cm) solitary RCC.
- Frozen sections of surgical margins were examined for completeness of resection.
- Mean follow-up was 40 months, with hot ischemia used in 14 cases.
Main Results:
- Complete local resection was achieved in all patients, preserving healthy kidney parenchyma.
- Renal function remained normal post-surgery.
- One local recurrence occurred, treated successfully with radical nephrectomy; all patients remain cancer-free.
Conclusions:
- Elective tumor enucleation is a safe and effective NSS option for select low-stage RCC.
- The procedure demonstrates a low risk of local recurrence.
- Further studies on pre-operative diagnostics, tumor size limits, minimally invasive approaches, and longer follow-up are needed for broader recommendation.
