Abstract:
Objective Todiscusstheangiographicfeaturesofhepaticneuroendocrineneoplasm(NEN),and to analyze the survival time of patients.Methods The clinical data of 60 patients with hepatic NEN were retrospectively reviewed.Transcatheter arterial chemoembolization (TACE),used as main therapy,was employed in 17 patients,22 patients received palliative treatment with no use of TACE,and 21 didn't receive any related treatment.The angiographic features of hepatic NEN were analyzed.Kaplan-Meier method was used to calculate the survival rate,and the survival prognostic factors were evaluated by Cox multivariate analysis method.Results Angiography showed that most neuroendocrine tumors (NETs) were characterized by hypovascular lesion,while neuroendocrine carcinomas (NECs) were manifested as hypervascular mass.The median overall survival time of 60 patients was 13.8 months.The 6-month,one-,2-and 3-year cumulative survival rates were 85.0％,52.0％,40.0％ and 33.8％,respectively.Cox regression analysis indicated that pathological grade of tumor (P=0.001) and treatment mode (P＜0.001) were the independent prognostic factors.Conclusion The rich or poor vascularity of hepatic NEN is helpful for the judgment of tumor grading.Patients whose hepatic NENs belong to high pathological grade (grade Ⅲ) usually have a poor prognosis.TACE is an effective therapy for hepatic NEN.
