The SSTR2-targeting radiopharmaceutical [68Ga(DOTATATE)] has demonstrated superior clinical resolution and sensitivity compared to the 111In-labelled SPECT tracer, [111In(DTPA-octreotide)], in identifying tumours expressing SSTR2 in neuroendocrine cancer patients [3]. The gene discussed is SSTR2; the disease is neuroendocrine carcinoma.
