CCT6A and neoplasm: Kaplan–Meier (K-M) curves showed that tumor CCT6A high expression was associated with decreased DFS (P < 0.001, χ2 = 26.823): the median DFS was 30.0 (95%CI 24.4–35.5) months in CCT6A high expression patients and was 48.0 (95%CI 42.5–53.5) months in CCT6A low expression patients (Fig. 2a).
