In this study, EV KRT17 and cytology/microhematuria scores during the first 6 months after TURBT (LV phase) were able to predictive recurrence-free survival (Fig. 5C) and at least those with high EV KRT17 expression indicated a relatively poor survival though statistical significance wasn’t obtained (Fig. 5B). Here, KRT17 is linked to Microscopic hematuria.
