Does fuhrman grade provide higher prognostic accuracy than nucleolar grade for papillary renal cell carcinoma?
Each grading system performs well but the predictive accuracy of Fuhrman grade is statistically superior to that of nucleolar grade and only Fuhrman grade provides independent prognostic information on patients with papillary renal cell carcinoma. Thus, Fuhrman grade should be the standard grading system for papillary renal cell carcinoma.
The three-dimensional understanding of the frontal recess is improved greatly by using both coronal and parasagittal reconstructed images as compared with coronal images alone. This had important implications on the planning of the surgery in the frontal recess.
