#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.

#1636 Preoperative Blood Neutrophil-To-Lymphocyte Ratio-Based Nomogram Predicts Lymph Node Metastasis in Patients of Resectable Pancreatic Neuroendocrine Tumors

Introduction: Neutrophil-to-lymphocyte ratio(NLR) is one of the systemic inflammation markers, which has prognostic values in many types of tumor. However, hardly no research has reported the relationship between NLR and pancreatic neuroendocrine tumors(panNETs).
