MUC4 high risk was also significantly associated with survival in bladder cancer (HR = 1.48), colon cancer (HR = 2.1), lung adenocarcinoma (HR = 1.7), lung squamous carcinoma (HR = 1.69), ovarian cancer (HR = 1.33), skin cancer (HR = 1.87) and stomach cancer (HR = 1.58) (Fig. 5a). Here, MUC4 is linked to ovarian cancer.
