Tumour cellularity size (TCS) as a new parameter to measure response to NET. (A) Comparison of radiological tumour size (assessed by MRI and USS, before and after NET) with TCS. The dotted line indicates the mean of path-TS obtained for those tumours. (B–D) Association between TCS and pathological (path-TR) (B) and radiological response assessed by MRI (C) or USS (D). (E–G) Association between TCS (E), tumour cellularity (F) and pathological tumour size (path-TS) (G) with changes in Ki67 (∆Ki67) after NET. p values were calculated using Kruskal–Wallis test
