Early Intervention 

Post hoc analysis of the phase III NETTER-1 study shows the benefit of early treatment with LUTATHERA® (lutetium [177Lu] oxodotreotide)1–4

Neuroendocrine tumours (NETs) tend to grow slowly but are often diagnosed late,5 resulting in increased burden, reduced therapeutic options and worse survival outcomes.5–7 Identifying progression is essential to improving patient outcomes, as it provides an opportunity to review treatment.8

Somatostatin receptor subtype 2 expression is greater in low-grade than in high-grade tumours.9 That’s why early administration of LUTATHERA® after first progression could maximise progression-free survival.3
