Figure 4. Tumor mutational burden (TMB) levels in SMARCA4-mutant colon cancers and stomach cancers. Microsatellite instability-high (MSI-H) colon cancers were excluded from all colon cancer patients. (A) Comparison of TMB levels was performed between the SMARCA4-WT and -mutant colon cancer groups and between the SMARCA4-WT and -mutant stomach cancer groups. (B) Comparison of TMB levels was performed between the SMARCA4-high and SMARCA4-low groups of SMARCA4-mutant colon cancers, and between the SMARCA4-high and SMARCA4-low groups of SMARCA4-mutant stomach cancers. *p<0.05 and **p<0.01 using the Mann-Whitney U-test.
