NES and neoplasm: In series 1, weak E‐cadherin expression and the EN‐switch were associated with maximum Nestin micro‐vessel density (Mann–Whitney, p = 0.042 and p = 0.003), increased vascular proliferation by Nestin‐Ki67 (see supplementary material, Table S1) and high tumour cell proliferation by Ki67 (Mann–Whitney p = 0.032 and p = 0.051).
