Overall survival was associated with a tumor weight of > 55 g (X2(1) = 13.534; p < 0.001; Kaplan–Meier method and log rank test), a tumor size of >7 cm (X2(1) = 11.462; p = 0.001; Kaplan–Meier method and log rank test), a Weiss score of ≥ 5 (X2(1) = 15.231; p < 0.001; Kaplan–Meier method and log rank test) and Ki-67 of > 8% (X2(1) = 18.294; p < 0.001; Kaplan–Meier method and log rank test). Here, MKI67 is linked to neoplasm.
