#4657 Should we use the growth modulation index (GMI) in response assessment in G2 neuroendocrine tumours (NETs)?

Introduction: Grade 2 (G2) neuroendocrine tumours (NETs) exhibit diverse behaviours ranging from indolent to aggressive malignancies. Growth Modulation Index (GMI) is the ratio between time to progression (TTP) with a line of therapy (TTPn) and that of the previous line of therapy (TTPn-1). A GMI value equal to or greater than 1,33 has been suggested as an indicator of clinical effectiveness beyond traditional metrics.
