Differences between the preoperative and postoperative AICS values according to rank and tumor location. The paired preoperative and postoperative values for left- and right-sided tumors in the rank B + C group (a and b, respectively) and the rank C group (c and d, respectively) are shown. The dotted lines show that the cut-off AICS values of 5 and 8 correspond to specificities of 80% and 95%, respectively. AICS: AminoIndex Cancer Screening. Pre-op: preoperative. Post-op: postoperative. **p < 0.01, ***p < 0.001, Wilcoxon signed rank test
