摘要
Objective:The aim of this study is to investigate the current status of the diagnosis and treatment of patients with pancreatic neuroendocrine neoplasms(pNENs)undergoing surgery in China.Methods:This is a multicenter cross-sectional study performed in China.Data from patients with pNENs undergoing surgery at 33 high-volume medical centers,where the number of pancreatectomies exceeds 20 cases per year,were collected and analyzed between March 1,2016 and February 28,2017.Results:In total,392 patients with pNENs were enrolled.The male to female ratio was 1.4.The majority of patients were aged between 40 and 70 years.65.6%of the patients had non-functional tumors.Among those with functional tumors,the percentages of insulinomas,gastrinomas,glucagonomas,and vasoactive intestinal peptide-secreting tumors were 94.8%,1.5%,2.2%,and 1.5%,respectively.Multidisciplinary team(MDT)discussion was conducted for 39.0%of the patients.Minimally invasive surgery was performed on 31.1%of the 392 patients.The incidence of grade B/C pancreatic fistula formation was 4.4%.A total of 89.0%of the surgeries achieved R0 resection,and 41.6%of the tumors were well differentiated.Lymph node metastasis was present in 8.9%of the patients.The percentages of patients with grades G1,G2,and G3 disease were 49.2%,45.7%,and 5.1%,respectively.Conclusion:This multicenter cross-sectional study systematically presents the current status of the diagnosis and treatment of patients with pNENs undergoing surgery in China.MDT consultation for pNENs has not been widely implemented in China.Although the incidence of surgical complications is relatively low,minimally invasive procedures should be further promoted.This study shows us how to improve the outcomes of these patients.
