Prevalence of Neuroendocrine Tumors in the Gastrointestinal and Hepatobiliary Systems
Background: Carcinoid tumors are the most common neuroendocrine tumors. In recent years, these tumors have had an increasein incidence, which is probably due to a higher number of them being incidentally found as a result of the rise of preventivemedicine.Objectives: This study aimed to analyze a se...

The mean tumor size was 10 mm. The localizationof the tumors was: stomach 43% (n = 43); duodenum 5% (n = 5); intestine 8% (n = 8); appendix 14% (n = 14); colon 4% (n = 4);rectum 19% (n = 19); pancreas 3% (n = 3); liver 2% (n = 2); gallbladder 1% (n = 1); primary tumor of unknown origin 1% (n = 1). Mostmultifocal tumors were in the stomach (20%; n = 20), followed by the duodenum (1%; n = 1) and intestine (1%; n = 1).

General survival at the closure of the study was 80%.Conclusions: Age and sex were similar to those described in the literature, while the colon and rectum represented 23% of all carcinoidtumors. There was a predominance of gastroduodenal and rectal carcinoid tumors, probably because the series analyzedwas essentially endoscopic. In comparison with the literature, less cases of metastases or carcinoid syndrome were recorded andsurvival was greater, perhaps due to earlier diagnosis and treatment.Modesto J Varas LorenzoFernando Munoz AgelRamon Abad BelandoElena MengualShiraz University of Medical Sciencesarticlecarcinoid tumorsneuroendocrine tumorcarcinoid syndromecolonrectumgastrointestinal systemhepatobiliary systemMedicineRENIranian Journal of Colorectal Research, Vol 7, Iss 2, Pp 1-7 (2019) |
