Tumor grading change at time of progressive disease.
Fig 1.
Ki67 change between 1st and 2nd histological evaluation according to the slope of tumor progression.
Interval between 1st and 2nd evaluation: < 12 months (circles), 12–48 months (triangles), > 48 months (squares). Horizontal lines = median values.

Ki67 change between 1st and 2nd histological evaluation.
SI-NENs = circles. PNENs = squares. Horizontal reference lines refer to Ki67 cut-off levels for G1 NENs (2%) and G2 NENs (20%).
