August 25, 2022 — A new gallium-68 PET radiotracer appears effective for predicting higher risk of disease progression and mortality in patients with neuroendocrine tumors, according to a study published August 18 in the Journal of Nuclear Medicine.
Conclusion: Tumor lesion uptake of 68Ga-NODAGA-E[c(RGDyK)]2 was evident in patients with all grades of NEN. High uptake was associated with a poorer prognosis. Further studies are warranted to establish if 68Ga-NODAGA-E[c(RGDyK)]2 PET/CT may become a prediction tool for identification of patients eligible for treatments targeting integrin αvβ3.
Why is this different to regular Ga68 Dotatate?
In the simplest of terms, Ga68 Dotatate is targeting somatostatin receptors which are known to be expressed by most NETs, it can help indicate if treatment using somatostatin analogue therapy is feasible. Integrin αvβ3 recognizing cell surface integrins is upregulated on endothelial cells during angiogenesis and on tumor cells. Due to its involvement in tumor growth, invasiveness/metastases, and angiogenesis, integrin αvβ3 is an attractive target in cancers. It could therefore become a prediction tool for the identification of patients eligible for treatments targeting integrin αvβ3.
However, Ga68 Dotatate really only confirms that a NET may be present, particularly when uptake is intense. Ga68 NODAGA-E[c(RGDyK)]2 may be associated with prognosis when uptake is high, and this could influence therapeutic choices and approach.
