  • CONCLUSIONS: The mean follow-up was 5.2 yr. There was a 28% increase in the number of patients undergoing surgical treatment over the study period. Joinpoint regression revealed a significant annual increase in partial nephrectomy (PN) and a small reduction in radical nephrectomy (RN). PN increased from 43% to 66% for tumors ≤4cm and from 10% to 18% for tumors of 4.1-7cm. Minimally invasive (MI) RN increased from 53% to 72% and MI PN from 25% to 64%, of which 55% of procedures were performed with robotic assistance in 2013. The geographical distribution of treatment approaches differed significantly. Both PN and MI approaches were more frequent in high-volume hospitals. Cox regression analysis revealed that PN, age, and Fuhrman grade and stage were independent predictors of survival. There were no significant differences in cancer-specific survival (p=0.8). The 5-yr RS for T1a disease was higher after PN than after RN.The rate of PN for tumors ≤7cm increased in the 6-yr study period. MI approaches increased for both RN and PN. This treatment shift coincides with the new guideline recommendations in 2010. The possible better survival for patients undergoing PN compared to RN indicates the importance of following evidence-based guidelines.
