Background.
This study is aimed at examining the prognostic role of pre-to-postoperative dynamics of De Ritis ratio (aspartate aminotransaminase (AST)/alanine aminotransaminase (ALT)) in patients with nonmetastatic renal cell carcinoma (RCC) following radical nephrectomy.
Methods.
We retrospectively reviewed the records of 670 patients who underwent radical nephrectomy for nonmetastatic RCC between 1996 and 2012 at our institution.
The cutoff points for preoperative (=1.0) and postoperative AST/ALT ratios (=1.12) were assigned based on the median values.
We categorized patients into four groups according to the dynamics of AST/ALT ratios: group 1 (lower (≤1.0) ⟶ lower (≤1.12)), group 2 (lower (≤1.0) ⟶ higher (>1.12)), group 3 (higher (>1.0) ⟶ lower (≤1.12)), and group 4 (higher (>1.0) → higher (>1.12)).
Results.
When grouped by a preoperative AST/ALT ratio alone, the groups were not statistically different in cancer-specific survival (CSS) or overall survival (OS).
In contrast, in Kaplan-Meier analysis, CSS (P=0.0296) and OS (P=0.0324) were both significantly shorter with an increased postoperative AST/ALT ratio.
According to the pre-to-postoperative dynamics of the AST/ALT ratio, group 2 (lower (≤1.0) ⟶ higher (>1.12)) had a significantly lower CSS (P=0.0028) and OS (P=0.0194) than the other groups.
On multivariate Cox regression analysis, the pre-to-postoperative dynamics of the AST/ALT ratio were a significant prognostic factor for CSS (hazard ratio, HR=3.45) and OS (HR=2.18).
Conclusion.
This study is the first to suggest that the dynamics of the pre-to-postoperative De Ritis ratio represent an independent prognostic factor for RCC patients following nephrectomy.
