Ovarian cancer diagnosis and treatment

Introduction The aim of the study was to examine management of pediatric appendiceal neuroendocrine tumors (ANETs) in Poland. Material and methods Records of 27 patients with ANET diagnosed incidentally after appendectomy in the last decade. Results Well-differentiated NET G1/G2 was diagnosed in 25 and well-differentiated neuroendocrine carcinoma G3 in 2 patients. Extended surgery was performed primarily in one instance and secondarily in 10 patients (right hemicolectomy in 9, ileocecal resection in 1) without adjuvant chemotherapy. Follow-up range was 1–121 months. Recurrence after secondary surgery was observed in 1 (3.7%) patient. Conclusions Applying ENETS guidelines resulted in 100% overall survival of patients with NET.
