Abstract:
Background:Duodenal neuroendocrine tumors(DNETs)are rare tumors,their disease characteristics are currently not well understood.At present,there are no research data on non-ampullary region DNETs in China.Aims:To analyze the clinical characteristics of patients with non-ampullary region DNETs in order to guide clinical practice.Methods:The clinical data ofnon-ampullary region DNETs diagnosed in the First Affiliated Hospital of Air Force Military Medical University from June 2011 to July 2022 were collected.Using the method of retrospective study,analyze the clinical characteristics of patients.Results:Twenty-two non-ampullary region DNETs patients were screened.Among them,8(36.4%)patients'tumor diameter<2 cm,14(63.6%)patients'tumor diameter≥2 cm.When non-ampullary region DNETs were diagnosed,the main clinical symptoms were abdominal distension(59.1%),followed by abdominal pain(41.0%).When diagnosed,half(50%)of patients with non-ampullary DNETs with tumor diameter<2 cm have no clinical symptoms.The clinical symptoms of non-ampullary DNETs patients with tumor diameter≥2 cm were mainly abdominal distension(85.7%),followed by abdominal pain(57.1%),and a few(14.3%)patients had no clinical symptoms.After diagnosed,the survival time of patients with tumor diameter<2 cm was longer than that of patients with tumor diameter≥2 cm(P=0.048).By the end of follow-up,the median survival time of patients with non-ampullary region DNETs was 451.0 months.Six patients had died,all of their tumor diameter were≥2 cm at diagnosis.Three of patients who died had stage Ⅳ at diagnosis,and all had liver metastases.Patients with tumor diameter<2 cm underwent surgical treatment and all survived after surgery.Conclusions:Abdominal distension is the main clinical manifestation of non-ampullary region DNETs patients,and the organ that is more likely to metastasize is the liver.The survival time of patients with non-ampullary region DNETs with tumor diameter<2 cm was longer than that of patients with tumor diameter≥2 cm.
