Oncological and Functional Outcomes of Laparoscopic Partial Nephrectomy in Renal Cell Carcinoma Stages T1 Versus T2a: Prospective Comparative Study.
RCC represents around 3% of all cancers, with the highest incidence occurring in Western countries . Within the several RCC risk factors identified, smoking, obesity, and hypertension are most strongly associated with RCC .
The EUA guidelines recommend PN for patients with T1 tumors, as PN preserved kidney function better after surgery, thereby potentially lowering the risk of development of cardiovascular disorders as well as improving overall survival(OS) for PN compared to RN, there is very limited evidence on the optimal surgical treatment for patients with larger renal masses (T2) .
Currently, the upper limit of PN indications remains undefined and is determined by an individual surgeon's expertise and preference. The degree of variability in the choice between PN and RN for a given tumor increases with tumor size. Surgeons committed to nephron-sparing are likely to expand the indications of PN, while those concerned with increased morbidity and doubtful of the clinical relevance of a moderate decrease in renal function are likely to perform RN, regardless of tumor size .
