After accounting for clincopathologic characteristics using propensity score matching, no significant differences were demonstrated were in any of the survival outcomes for radical and partial nephrectomy (all p>0.05). However, increased in 30 day complications were identified in the partial nephrectomy cohort (p<0.001). A sub-analysis of cT2 tumors only also demonstrated no differences in survival outcomes.
This study supports radical nephrectomy in this cohort, due to the less perioperative complications. However, even with the use of matched propensity models, selection and unaccounted biases do exist. Future prospective studies will continue to shed information on this controversial topic.
