Neuroendocrine Neoplasms in Childhood and Adolescents Abstract #652

Introduction: NEN are very rare tumors in children and adolescents with predominance in adolescent girls. The annual incidence is about 1.14:1 million. The most frequent localization is appendix. Bronchial NEN, even extremly rare, is the most frequent primary epithelial lung tumor in children.
Aim(s): Authors present retrospective monoinstitutional study of NEN in children and adolescents younger than 20 years of age treated in a pediatric cancer center within a period of 14 years.
Materials and methods: Retrospective analysis of 47 patients with NEN from four to 19 years of age. Median age 15 years for WDET, 14 years for NEC. Localization - appendix 42, jejunum 1, bronchi 1, liver 1, colon 1, neck 1. Histopathology - 43 WDET G1, 2 WDET G 2 and 2 NEC. All NEN are characteriued and treated according to ENETS Guidelines. All patients with WDET (appendix and jejunum) underwent R0 resection of the tumor, one girl with liver mets achieved CR after LTX. One girl with NEC (colon) underwent only biopsy, girl with MCC - R0 resection, RT and CHT.

#128 Multidisciplinary reference centers: the need for combined expertise in the diagnosis and treatment of neuroendocrine tumors
Introduction: Neuroendocrine tumors (NETs) are a heterogeneous group of malignancies with increasing incidence (Yao et al. J Clin Oncol 2008;26:3063–72). Multidisciplinary reference centers (MRCs) can potentially offer better clinical outcomes by integrating and coordinating expert care from many specialties, reducing delays in treatments and referrals, and allowing for accrual to clinical trials. MRCs have achieved improved outcomes in ovarian, breast and lung cancers (Pollock. Ann Surg 2008;248:510–6; Gabel et al. Cancer 1997;79:2380–4; Forrest et al. Br J Cancer 2005;93:977–8). Despite this, MRCs focusing on NETs are uncommon.

#136 Prevalence, severity and clinical outcome of malnutrition in gastroenteropancreatic neuroendocrine tumors
Introduction: Malnutrition is well-known to unfavorably influence clinical prognosis in patients (pts) with malignant diseases. However, in patients with neuroendocrine tumors (NET) prevalence and outcome of malnutrition are unknown although the gastroenteropancreatic system is most frequently involved.

#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.
