#1129 Expression and Clinical Significance of Merkel Cell Polyomavirus Large T Antigen in Merkel Cell Carcinoma
Introduction: Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine skin cancer that is often associated with Merkel cell polyomavirus (MCPyV) infection. MCPyV expression and its relationship with clinical features and prognosis in MCC remain unclear.

#2148 Tumor Microenvironment in Merkel Cell Carcinoma: Association with Merkel Cell Polyomavirus and Clinico-Pathological Features in a Retrospective Cohort Study
Introduction: MCC is a rare and aggressive skin cancer with a neuroendocrine phenotype.Association between MCC and Polyomavirus is known.PD-1 and PD-L1 have recently become key players in the therapeutic landscape.

#69 Frequent biological association of Merkel cell polyomavirus with Merkel cell carcinomas
Introduction: Merkel cell polyomavirus (MCPyV) DNA has been detected by PCR in 75–100% of Merkel cell carcinomas (MCC), an aggressive neuroendocrine skin cancer. MCPyV is a 5.4 kb DNA virus that expresses tumor (T) antigen in tumor tissues.

#1402 Merkel Cell Carcinoma of Lymph Node Without Skin Primary Can - and Should - Be Distinguished from Others Metastatic Neuroendocrine Carcinoma
Introduction: Merkel cell carcinoma of lymph node without primary tumour (MCCNWP) is a rare tumour which can be misinterpreted as lymph node metastasis (LNM) from a high-grade neuroendocrine carcinoma (NEC) on histological examination. However, this distinction is crucial for therapeutic management.

#1864 Analysis of mTOR, CXCR4 and PD-1 Checkpoint Pathways in Merkel Cell Neuroendocrine Carcinomas: Correlations with Prognosis and Viral Status
Introduction: Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous neuroendocrine tumor. Prognostic factors currently included in the reference AJCC classification are mainly clinical.

#1726 A Long-Term Complete Response (CR) of Avelumab in Patient (pt) with Advanced Merkel Cell Carcinoma (MCC)
Introduction: MCC is a rare and aggressive cutaneous neuroendocrine cancer linked to exposure to the Merkel Polyomavirus (MCPyV). Cisplatin and VP16 chemo may be an effective treatment for metastatic MCC, but responses are often transient. The blockade of programmed death 1 (PD-1) immune inhibitory pathway by avelumab, an anti-PD-L1 checkpoint inhibitor, is being investigated in solid neoplasms. This strategy can also be of interest in MCC because these tumors often express PD-L1

#2297 Merkel Cell Carcinomas in New Zealand: Virus or Ultra Violet?
Introduction: Merkel Cell Carcinoma (MCC) is a rare Neuroendocrine skin tumour. MCC behavior is more aggressive than the more common Melanoma, with treatments often restricted to surgery or radiotherapy, although immunotherapy holds promise overseas. In 2008, a USA study identified an oncogenic polyomavirus (MCPyV) present in eight of ten tested MCC tumours. Studies from across Europe and the USA confirmed MCPyV presence in ~80% of all MCCs. However, a cohort from Australia found a rate of just 24%, suggesting an alternative mechanism; ultra violet (UV) exposure was suspected and later confirmed using genomic mutational signature analysis. Are these are two separate diseases, requiring different clinical management strategies for best patient outcomes?

#634 Merkel Cell Carcinoma in a Nine-Year-Old Girl
Introduction: Merkel cell carcinoma (MCC) of the skin is a rare neuroendocrine tumor characterized by its rapid growth and aggressive clinical behavior. MCC is a typical tumor of older age (average age is 65 years). In children and adolescents less than 20 years of age, it is extremely rare. Information regarding MCC in childhood can be found in the literature only in the form of individual case reports. Due to the rarity of MCC in the young population, any clinical studies or treatment recommendations in these patients are missing.

#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.
