title: EPIDEMIOLOGICAL REGISTRY OF NEUROENDOCRINE TUMORS IN BULGARIA--A PILOT SURVEY.
abstract: The National registry of patients with neuroendocrine tumors (NET) in Bulgaria was established in 2013 as a joint initiative of the Bulgarian Surgical Society and the Institute for Rare Diseases. The register aims to explore the epidemiology of NET in Bulgaria, as well as the different diagnostic and treatment approaches for the disease throughout the country. This the first of its kind retrospective study of NET in the country is covering the period January 2012 - January 2013. A total of 127 patients with NET were identified. At the time of the survey the average age of patients with NET was 58.61 ± 15.59 years. The data show almost equal distribution between the genders with a slight predominance of women. The largest relative part of NET is those of NET located in the gastrointestinal tract (54.10 ± 4.51%), followed by those located in the pancreas (12.30 ± 2.97%) and in the lungs (10.66 ± 2.79%). In 72.44 ± 3.96% of the patients a immunohistochemical diagnosis was performed. The study confirmed the leading role of the surgery method of the NET management. In 65.83 ± 4.33% of the patients a radical removal of the tumor was conducted, while the relative part of the undertaken partial resection was 7.50 ± 2.40%. A statistically significant association between the type of surgical treatment and during the follow-up of patients was found. An update of the information in the register will allow a more precise determining of the distribution and management of NET in Bulgaria.
