Baseline characteristics were comparable between the two groups, including age (P = 0.940), tumor size (P = 0.474), grade (P = 1.000), lymph node status (P = 0.084), tumor subtype (P = 0.822), Ki-67 level (P = 0.599), and clinical stage (P = 0.580). This evidence concerns the gene MKI67 and neoplasm.
