#3070 Activity and Safety of Avelumab in Merkel Cell Carcinoma: Our Experience

Introduction: Merkel cell carcinoma (MCC) is an aggressive neuroendocrine carcinoma of the skin. The use of checkpoint inhibitors has shown good results in the treatment of advanced MCC. Avelumab is a PD-L1 inhibitor able to prevent the inactivation of the T lymphocytes. We report a serie of consecutive MCC cases treated with Avelumab in two centres

#2978 Policy Barriers to Increasing Access to Radioligand Therapy for Neuroendocrine Cancers

Introduction: Radioligand therapy is a relatively new treatment approach used in a small number of neuroendocrine cancers and has been shown to improve overall survival and quality of life. Yet because it uses radioactivity, there are particular barriers to its greater integration into cancer care. As neuroendocrine cancers are rare, it is all the more urgent that these barriers be understood and overcome so that this treatment modality can become available to all patients who may benefit.

#2870 When It Comes to the Diagnostic of Neuroendocrine Neoplasms (NEN), Not All Markers and Clones Were Made Equal. Assessment of 5 Makers in 466 NEN from 10 Anatomical Sites

Introduction: Histological diagnostic of neuroendocrine neoplasms (NEN) relies on morphological criteria and expression of several neuroendocrine marker assessed by immunohistochemistry. Systematic large evaluation of classical (chromogranin A (chrA), synaptophysin (Syn), CD56) and emerging (chromogranin B (chrB), INSM1) markers are lacking.

#2832 Lymph Node Merkel Cell Carcinoma without Primary: Long Term Survival

Introduction: Merkel cell carcinoma (MCC) is a rare aggressive cutaneous neuroendocrine carcinoma with a high rate of metastasis. Approximately 5% of MCC are found in the lymph nodes (LNs) without a primary tumor on the skin.
