MKI67 and neoplasm: Evaluation of 584 miRNA expression profiles between clinical and pathological factors, including sex, age (≤50 vs. >50), tumor size (<10 mm vs. ≥10 mm), LVI, Ki-67 index (<3% vs. ≥3%), and WHO grade (grade 1 vs. grade 2), showed no significant differences among miRNA expression levels except for the mitotic index.
