[Small renal cell carcinoma-active surveillance and ablation]

Area of Science:

• Urology
• Oncology
• Nephrology

Background:

• Increasing incidence of renal cell carcinoma (RCC) globally.
• Rising prevalence of chronic kidney disease (CKD) and associated patient morbidity.
• Shift in treatment paradigm from radical nephrectomy to kidney-sparing techniques like partial nephrectomy and tumor enucleation.

Purpose of the Study:

• To review current and emerging treatment alternatives for renal cell carcinoma (RCC).
• To evaluate the role of active surveillance and minimally invasive ablative therapies in managing RCC.
• To discuss the potential of novel ablation techniques for selected RCC patients.

Main Methods:

• Review of current literature on RCC treatment modalities.
• Analysis of established and experimental ablative techniques for RCC.
• Comparison of outcomes for partial nephrectomy, ablation, and surveillance.

Main Results:

• Partial nephrectomy and tumor enucleation are standard for localized RCC.
• Active surveillance is a viable option for select patients, involving controlled treatment delay.
• Percutaneous radiofrequency ablation and laparoscopic cryoablation are established alternatives.
• Emerging ablative therapies (HIFU, IRE, microwave, SAbR, brachytherapy) show promise but remain largely experimental.

Conclusions:

• Treatment for renal cell carcinoma (RCC) is evolving towards kidney-sparing approaches.
• Active surveillance and established ablative therapies provide crucial alternatives for high-risk patients.
• Novel ablation techniques require further investigation to establish their role in RCC management.
