However, the comparative study with two techniques remains lacking. The aim of this study was to evaluate midterm results of MWA vs. LRN in patients with small RCC. A total of 426 patients with ≤4cm RCC were included from April 2006 to October 2012. Ninety-eight patients underwent MWA and 328 patients LRN. The survival, recurrence, and renal function changes were compared between two treatments. Although overall survival after MWA (82.6% at 5years) was lower than those after LRN (98.6% at 5years, p=0.0004), the RCC-related survival (97% at 5years) was comparable to those following LRN (98% at 5years, p=0.38). One local tumor progress occurred at 32months after MWA and none after LRN. The major complication rates were comparable between two techniques (1.7% in MWA vs. 1.5% in LRN, p=0.75), but MWA showed less renal function damage than LRN (p<0.0001). The multivariate analysis showed the presence of postablation extrarenal metastasis may become a predictor of the oncologic outcome (p=0.059) and treatment modality had no influence (p=0.965). This study demonstrates thatMWA and LRN provide comparable results in small RCC outcomes.
