Mesentery morphological features on computed tomography for preoperative prediction of tumor invasion and lymph node metastasis in colon cancer

Figure 1 The Box-whisker plots and receiver operating characteristic plots for tumor-contributed computed tomography value to discriminate T and N stages in the training cohort. A: The Box-whisker plot for tumor-contributed computed tomography value (CT-T value) in patients with T1/2 vs T3/4 stages; B: The Box-whisker plot for CT-T values in patients with N0 vs N1/2 stages; C: The receiver operating characteristic (ROC) plot for CT-T value to discriminate T1/2 vs T3/4 stages; D: The ROC plot for CT-T value to discriminate N0 vs N1/2 stages (^aP < 0.01). AUC: Area under the receiver operating characteristic curve; CT-T: Tumor-contributed computed tomography.

Figure 2 The Box-whisker plots and receiver operating characteristic plots for tumor-contributed computed tomography value to discriminate T and N stages in the validation cohort. A: The Box-whisker plot for tumor-contributed computed tomography value (CT-T value) values in patients with T1/2 vs T3/4 stages; B: The Box-whisker plot for CT-T values in patients with N0 vs N1/2 stages; C: The receiver operating characteristic (ROC) plot for CT-T value to discriminate T1/2 vs T3/4 stages; D: The ROC plot for CT-T value to discriminate N0 vs N1/2 stages (^aP < 0.01). AUC: Area under the receiver operating characteristic curve; CT-T: Tumor-contributed computed tomography.

Figure 3 Correlation between clinical characteristics and mesenteric tumor-contributed computed tomography value. A: Correlation analysis between clinical characteristics and mesenteric tumor-contributed computed tomography value (CT-T value) value; B: Correlation plot between carcinoembryonic antigen and mesenteric CT-T value. BMI: Body mass index; CA19-9: Carbohydrate antigen 19-9; CEA: Carcinoembryonic antigen; CT: Computed tomography; CT-T: Tumor-contributed computed tomography; FDR: false discovery rate; GHb: Glycosylated hemoglobin; HDL-C: High-density lipoprotein cholesterol; LDL-C: Low-density lipoprotein cholesterol; TC: Total cholesterol; TG: Triglyceride.
