#4593 Excellent response to Ac-225 DOTATATE therapy in a patient with small cell lung cancer

Introduction: Peptide receptor radionuclide therapy (PRRT) is a validated treatment for patients with NETs overexpressing somatostatin receptors (SSTR). IHC analysis indicates that up to 50% of small cell lung cancer (SCLC) tumours are SSTR2 positive and thus can be targeted by SSR imaging and PRRT. Therapy with α-emitting radionuclides, such as Ac225, may offer several advantages over β-emitters by having higher energy transfer and more effective cancer cell death.

#4449 Treatment of MiNEN with peptide receptor radionuclide therapy

Introduction: Mixed non-neuroendocrine and neuroendocrine neoplasms (MiNENs) of gastrointestinal tract are rare tumours with characteristic histological features include at least 30% of both neuroendocrine and non-neuroendocrine components of the whole neoplasm. They are usually treated with surgical resection and chemotherapy in advanced disease. However, there is scarcity of data for the use of peptide receptor radionuclide therapy (PRRT) in these tumours.

#4409 The value of NETest 2.0 in stratifying patients with suspected NEN for formal diagnostic evaluation – Real-world data

Introduction: An unmet need in NEN diagnosis is better risk stratification for individuals with suspected disease (based on symptoms or imaging), enabling efficient identification of those needing further evaluation and tissue diagnosis, thus speeding the process and reducing costs. NETest 2.0, a biomarker based on a 51-gene mRNA panel, was developed for diagnosing neuroendocrine neoplasia (NEN).
