Abstract:Background
To explore the value of multiparametric MRI markers for preoperative prediction of Ki-67 expression among patients with rectal cancer.
Methods
Data from 259 patients with postoperative pathological confirmation of rectal adenocarcinoma who had received enhanced MRI and Ki-67 detection was divided into 4 cohorts: training (139 cases), internal validation (in-valid, 60 cases), and external validation (ex-valid, 60 cases) cohorts. The patie… Show more
