STC2 and cancer: The results demonstrated that the expression of STC2 was related to TMB in six types of cancers, including CESC (R = 0.13, p = 0.03), LUAD (R = 0.15, p = 0.001), THYM (R = 0.29, p = 0.001), READ (R = 0.25, p = 0.02), BRCA (R = −0.11, p = 0.001), and ESCA (R = −0.15, p = 0.04) (Figure 10A).
