Determination of Fuhrman grade (FG) on biopsies of renal masses is relatively
inaccurate, being prone to underestimating the true grade as ascertained from
surgical specimens. This study evaluated whether anatomical features of tumors
could predict tumor upgrading between core biopsies and surgical specimens. We
prospectively enrolled 249 patients undergoing surgical resection of solid renal
masses at our institution from 2012 to 2013. Tumor anatomical features were
defined using RENAL nephrometry scores. Two peripheral and 1 central ex vivo core
biopsies were taken from surgical specimens with an F18-gauge needle. Logistic
regression was used to assess associations between covariates and FG upgrading. A
comprehensive nomogram was constructed to quantitate the probability of tumor
upgrading. The median tumor size was 4.75?cm and FG upgrading occurred in 43.6%
of cases. In tumors of low, intermediate, and high complexity, the risk of FG
upgrading was 22.0%, 47.6%, and 50.6%, respectively. According to multivariate
analyses, anatomical features R (radius) and L (location) scores correlated
significantly with FG upgrading. A combination of anatomical features and core
biopsy findings predicted tumor upgrading with an accuracy of 0.884. With a
threshold of 30%, our nomogram identified 92.4% of cases with upgrading; however,
it overrated 26.8% of patients without upgrading. This ex vivo prospective study
demonstrated that RENAL nephrometry score can aid prediction of FG upgrading
between core biopsies and surgical specimens. Our nomogram uses anatomical
features to predict true FG from renal biopsies.
