Identification and validation of colon cancer immunity-related subgroups. a In ssGSEA, 29 immune-related gene sets are enriched with colon cancer. These gene sets are composed of immune cells and immune processes. The tumor purity, ESTIMATE score, immune score and stromal score are also shown in this heatmap. b Consensus clustering cumulative distribution function (CDF) for k = 2 to 9. c Relative change in area under CDF curve for k = 2 to 9. d Heatmap of sample clustering at consensus k = 3. e–k Survival analysis of the total TCGA cohort, samples without lymphatic invasion. samples without metastasis, samples without lymph node metastasis, samples which are stage1 or 2, samples which are T3 or T4 and samples with age less than 60
