IL2 and neoplasm: Cluster A was also associated with a better survival rate (Figure 1C) and was enriched in the interferon-alpha response, interferon-gamma response, and IL2 stat5 signaling (Figure 1D), which demonstrated that cluster A more readily produced an immune response than cluster B. Furthermore, this study derived a correlation coefficient heatmap for visualizing 28 tumor-infiltrating immune cell types (Figure 1E).
