ABSTRACT
Objective To evaluate GIPR protein expression in predicting prognosis of appendical neuroendocrine tumors (A-NET) patients.Methods The clinical data of 40 A-NET cases surgically treated from June 2007 to June 2017 at Tianjin Police Hospital were analyzed.The expression of GIPR markers was detected by immunohistochemistry (IHC).Results There were 25 male and 15 female patients,with an median age of 59 years.Sex,tumor site,tumor size,tumor stage and lymph node metastasis were not related to prognosis (P ＞ 0.05).The expression of GIPR was positive in 18 cases and negative in 22 cases.There were 16 cases in G1 stage,20 cases in G2,4 cases in G3.The expression of GIPR protein and pathological grades were related to prognosis (P ＜ 0.05).Conclusions Symptoms of appendix neuroendocrine tumor are nonspecific.Diagnosis is dependent on pathological examination and immunohistochemistry.Positive GIPR protein expression predicts poor prognosis for A-NETs patients.
