dc.description.abstractBackground: Grading of linear parameters into meaningful (clinically relevant) clusters is a well-known challenge. Recently several groupshave proposed to change the Ki67 index cut-off for grade 1 (G1) category for PanNETs from < 3% to < 5%. This proposal presupposes thatthe cases with Ki67 index of 3-5% are NOT clinically different than the 0-3% group and thus can be lumped together with the current G1 (0-3% cases), instead of their current home in the G2 category (> 3%).
