A Long-Term Complete Response (CR) of Avelumab in Patient (pt) with Advanced Merkel Cell Carcinoma (MCC) Abstract #1726

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
Aim(s): to describe a case of advanced MCC in long term CR during immunotherapy with Avelumab
Materials and methods: A 60-year-old man was referred to our center in July 2015 for advanced MCC with nodes and skin lesions, after platinum-based chemo. A phase II, open-label, multicenter trial to investigate the activity and safety of avelumab in pts with advanced MCC was open for enrolment at our institution. The pt was eligible for treatment and started the treatment in August 2015

#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.

#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.
