2. Figure 1
Heat maps of gene expression associated with (A) survival and (B) the number of involved lymph nodes with the corresponding histograms of Pearson correlation coefficients. On the heat maps samples are ranked on the y-axis in order of (A) increasing survival and (B) increasing number of involved lymph nodes, and the genes associated with this feature are ranked along the x-axis. The blue bars on the histograms represent the distribution of the data and the red lines represent the distribution expected from the Monte Carlo simulation.

4. Figure 3
Kaplan–Meier plots of survival comparing internal validation patients with dysregulation and no dysregulation of (A) DCK (χ2LR, 4.46; 1 df; P = .035), (B) PAPSS2 (χ2LR, 12.11; 1 df; P = .001), (C) SIRT2 (χ2LR, 3.97; 1 df; P = .046), and (D) TRIM44 (χ2LR, 3.35; 1 df; P = .063). Notches represent censored data; P values were calculated using the log-rank (Mantel–Cox) test.

5. Figure 4
Kaplan–Meier plots of survival comparing outcomes for patients with 0 of 4, 1–2 of 4, and 3–4 of 4 genes dysregulated for (A) the complete external validation dataset (χ2LR, ; 2 df; P = 0.001), (B) external validation set patients who were chemotherapy-naive (χ2LR, 4.323; 2 df; P = .038), and (C) external validation dataset patients who had received neoadjuvant chemotherapy (χ2LR, 5.013; 2 df; P = .025). Notches represent censored data; P values were calculated using the log-rank (Mantel–Cox) test.

6. Figure 5
Kaplan–Meier plots of survival comparing external validation patients with dysregulation and no dysregulation of (A) DCK (χ2LR, 0.038; 1 df; P = .85), (B) PAPSS2 (χ2LR, 1.91; 1 df; P = .17), (C) SIRT2 (χ2LR, 1.97; 1 df; P = .16), and (D) TRIM44 (χ2LR, 6.86; 1 df; P = .009). Notches represent censored data; P values were calculated using the log-rank (Mantel–Cox) test.
