undergoing PN were on average 2.5 yr younger and
presented with smaller tumors. Indeed, such a finding
might account for selection bias in favor of PN. However,
patient age and tumor size per se are very limited, and
they may not account for multifactorial parameters
encompassing patient comorbidity status and tumor
complexity, respectively, which may have a more over-
arching impact on patient outcomes. Unfortunately, it was
not possible to perform a pooled analysis of more reliable
parameters assessing patient surgical risk, such as American
