#4628 Triple negative breast neuroendocrine carcinoma in older patient: A rare entity

Introduction: Neuroendocrine breast carcinoma is a rare histological form of breast cancer, that represent 0.1% of all breast cancers and is recognised by the World Health Organization as a distinct entity. Characterised by a non-specific clinical and radiological presentation. Therapeutic management is not codified and is usually superimposed on that of classical breast cancer.

#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.
