#3076 Endometrial Small Cell Neuroendocrine Carcinoma: Case Report and Literature Review
Introduction: Endometrial small-cell neuroendocrine carcinoma (ESCNEC) is extremely rare. It is characterized by early regional and systemic spread leading to rapid development of lymph nodes, pelvic and extrapelvic metastasis and compromising the outcome.

#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.

#3005 Comparison between Tang and WHO 5th Edition Grade Classification for Goblet Cell Adenocarcinomas
Introduction: Appendiceal GCAs (previously Goblet Cell Carcinoids) are composed of cells with secretory phenotypes. Several grading systems to predict behaviour are available (e.g.Tang). The latest WHO 5th edition adopted a grading system similar to colon adenocarcinomas.

#2774 Metastatic Merkel Cell Carcinoma Associated Paraneoplastic Hyponatraemia: Response to Avelumab
Introduction: Merkel cell carcinoma (MCC) is rare, encompassing primary cutaneous neuroendocrine carcinoma.It has an aggressive natural history, and exhibits high response rates to radiotherapy & chemotherapy but often of short duration.

#2796 Avelumab for Advanced Merkel Cell Carcinoma in the Netherlands; A Nationwide Survey
Introduction: Merkel cell carcinoma (MCC) is a rare, tumor of the skin associated with high recurrence rates and poor survival. Clinical trials have shown activity of checkpoint inhibitors targeting programmed death-(ligand)-1 (PD-(L)1). Avelumab is the only PD-L1 inhibitor that has been approved in the Netherlands for advanced/metastatic MCC (mMCC).

#2927 Systemic Chemotherapy for Inoperable Goblet Cell Adenocarcinomas (GCAs) and the Role of Anti-EGFR Antibodies
Introduction: Appendiceal GCAs (previously Goblet Cell Carcinoids) have variable behaviour. Systemic chemotherapy (Chemo) is often extrapolated from colon cancer. KRAS mutations (KRAS-mut) are rare and more often present in Tang-C/high grade. The role of anti-EGFR antibodies (MoAb) is unknown.

#2885 Ectopic Neuroendocrine Carcinoma: An Occult Source of ACTH
Introduction: About 250 cases of ectopic ACTH-producing neuroendocrine carcinoma (ACTH-NEC) have been reported; however metastatic ACTH-NEC of unknown primary is very rare. Usually are characterized by having a large cell, small cell, poorly differentiated or anaplastic cell, and Ki-67 index between 40-90%.

#3035 Large-Cell Neuroendocrine Carcinoma of the Lung in Elderly Patient: Case Report and Review of Literature
Introduction: Lung neuroendocrine tumors account for less than 25% of lung cancers.Which is a rare malignant tumor with an aggressive profile has often already affected lymph nodes at presentation and it is de novo metastatic in nearly 40% of cases.

#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
