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.
ABSTRACT
Objective To explore the clinical pathological characteristics and prognostic factors of patients with neuroendocrine tumor of the appendix.Methods Data of 42 cases of the appendiceal neuroendocrine tumor from June 2006 to June 2016 at Tianjin Police Hospital were analyzed.Tumors were classified according to 2010 WHO classification.The survival curves were drawn using Kaplan-Meier method.Univariate analysis was performed by the Log-rank test.Results There were 27 males and 15 females,with median age of 60 years.Tumors located in the head of the appendix in 37 cases,in the body in 2 cases and at the base in 3 cases.The median of tumor sizes were 1.2 cm.G1 in 17 cases,G2 in 21 cases,G3 in 4 cases.The follow-up rate was 100％.The overall 1-year survival rate was 92％.Conclusions The clinical symptoms of appendiceal neuroendocrine tumors are most often nonspecific.The diagnosis depends on pathological examination and immunohistochemistry,and prognosis varies with pathological grades.
ABSTRACT
The adiponeetin mRNA expression and secretion of human omental and subcutaneous preadipocytes were increaed by renin-angiotensin system (RAS) bloekers. Compared with thiazolidinedione, RAS blockers have stronger effects on human omental preadipoeytes in adiponeetin mRNA expression and secretion,suggesting a potential benefit of RAS blockers on metabolic syndrome with characteristic intra-abdominal obesity.
