MKI67 and neoplasm: It shows that only lymph node status was marginally associated with DMF survival [hazard ratio (HR): 2.206, 95% confidence interval (CI): 0.985–4.942; P = 0.054], whereas other factors, including patient age at diagnosis, tumor size, histological grade, lymphovascular invasion, P53 status, Ki-67 index (14% as threshold [29]) and type of surgery, were not statistically significant predictors.
