MKI67 and neoplasm: Univariate analysis for the expression of Ki-67, performed by categorising the tumour samples into Ki-67Low (proliferation rate ≤ median proliferation rate = 15%) and Ki-67High (proliferation rate > median proliferation rate = 15%) showed no significant difference for overall survival and recurrence-free survival (Ki-67Low: median overall survival 21.8 months, Ki-67High: median overall survival 17.7 months, p = 0.27, Ki-67Low: recurrence-free survival 14 months, Ki-67High: recurrence-free survival 15 months, p = 0.78).
