摘要

cqvip:Background:Primary hepatic neuroendocrine neoplasms(PHNENs)are extremely rare and few articles have compared the prognosis of PHNENs with other neuroendocrine neoplasms(NENs).This study aimed to investigate the different prognosis between PHNENs and pancreatic NEN(Pan NENs)and evaluate the relevant prognosis-related factors.Methods:From January 2012 to October 2016,a total of 44 NENs patients were enrolled and divided into two groups according to the primary tumor location which were named group PHNENs(liver;n=12)and group Pan NENs(pancreas;n=32).Demographic,clinical characteristics and survival data were compared between the two groups with Kaplan-Meier method and log-rank tests.Prognostic factors were analyzed using the Cox regression model.Results:The overall survival of group PHNENs and group Pan NENs were 25.4±6.7 months and 39.8±3.7 months,respectively(P=0.037).The cumulative survival of group Pan NENs was significantly higher than that of group PHNENs(P=0.029).Univariate analysis revealed that sex,albumin,total bilirubin,total bile acid,aspartate aminotransferase,alkaline phosphatase,α-fetoprotein and carbohydrate antigen 19-9,histological types,treatments and primary tumor site were the prognostic factors.Further multivariate analysis indicated that albumin(P=0.008),histological types NEC(P=0.035)and treatments(P=0.005)were the independent prognostic factors.Based on the histological types,the cumulative survival of patients with well-differentiated neuroendocrine tumor was significant higher than that of patients with poorly differentiated neuroendocrine carcinoma in group PHNENs(P=0.022),but not in group Pan NENs(P>0.05).According to the different treatments,patients who received surgery had significantly higher cumulative survival than those with conservative treatment in both groups(P<0.05).Conclusions:PHNENs have lower survival compared to Pan NENs.Histological types and treatments affect the prognosis.Surgical resection still remains the first line of treatment for resectable lesions and can significantly improve the survival.
