#4636 Maximising the use of pancreatic enzyme replacement therapy (PERT) among patients with gastroenteropancreatic neuroendocrine neoplasms (GEPNENs) and exocrine pancreatic insufficiency (EPI)

Introduction: Patients with GEPNENs frequently develop EPI due to surgical resection or use of somatostatin analogues (SSAs), however it is significantly underdiagnosed. Untreated EPI has significant impact on overall quality of life with patients with GEPNENs.

#4601 Pembrolizumab combined with cisplatin or carboplatin and etoposide in treatment naïve advanced Merkel cell carcinoma (MCC): The phase II PANDORA Trial

Introduction: MCC is a rare and aggressive skin neuroendocrine tumour with high metastatic potential and mortality. Therapeutic options in metastatic/unresectable MCC are based on immunotherapy or platinum-based chemotherapy. However, a subgroup of patients (pts) has primary immunoresistance disease, so it would be important discover active upfront combinations. PANDORA trial [NCT 06086288] is an open-label, multicentre, single-arm phase II trial evaluating the activity and safety of pembrolizumab (PEM) combined with platinum-based chemotherapy as 1st line treatment in pts with metastatic, unresectable or recurrence MCC. Supported in part by a research grant from Investigator-Initiated Studies Program of MSD.

#4597 FIT-NETs: Assessing the effects of an exercise programme on the physical and emotional well-being of patients with advanced G1-2 NETs of GEP or unknown origin

Introduction: Physical activity programs in solid tumours have shown to improve symptom control and even survival, but their impact on NENs remains unexplored. Advanced disease, systemic therapy, and hormonal secretion in these tumours often lead to muscle wasting and sarcopenia.

#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.
