摘 要:目的探讨胃肠道神经内分泌肿瘤(GI-NEN)患者的病理分型及预后危险因素,为临床诊治提供参考。方法回顾性分析2007年11月至2016年12月期间于上海仁济医院就诊的119例GI-NEN患者的临床病理资料。参照2010版WHO神经内分泌肿瘤分类及分级标准对其进行病理分型,了解本组患者肿瘤的恶性程度。采用Kaplan-Meier法计算其总体生存率;并通过Cox回归模型进行预后危险因素分析,纳入分析的因素除了常规的临床病理因素外,还包括血小板/淋巴细胞比值(PLR)和中性粒/淋巴细胞比值(NLR)。结果119例GI-NEN患者中男性83例(69.7%),女性36例(30.3%);年龄24~86(中位数61)岁。肿瘤位于胃70例(58.8%),十二指肠10例(8.4%),小肠2例(1.7%),阑尾3例(2.5%),结肠12例(10.1%),直肠22例(18.5%)。肿瘤直径为0.6~20(5.4 ± 3.3)cm。病理分型:G1级神经内分泌瘤25例,G2级神经内分泌瘤7例,G3级神经内分泌癌87例。119例患者中113例(95.0%)获得完整随访,中位随访时间为75(1~112)月,5年总体生存率为58.4%,其中G1级、G2级和G3级患者分别为100%、71.4%和44.4%,差异有统计学意义(P= 0.000)。单因素预后分析结果显示,年龄≥61岁(P= 0.000)、肿瘤原发于胃、十二指肠和结肠(P= 0.041)、肿瘤≥4 cm(P= 0.002)、病理分型为G3级(P= 0.000)、TNM分期更晚(P= 0.000)及术前血PLR≥133(P= 0.017)者5年生存率更低,但术前血NLR水平与预后无关(P= 0.263)。多因素分析结果显示,患者年龄(HR= 3.036,95%CI:1.548~5.956,P= 0.001)、肿瘤病理分型(HR= 1.852,95%CI:1.099~3.122,P= 0.021)、淋巴结转移(HR= 2.635,95%CI:1.198~5.797,P= 0.016)及远处转移(HR= 2.685,95%CI:1.383~5.214,P= 0.004)是影响患者预后的独立危险因素,但血PLR水平未获证实(HR= 1.735,95%CI:0.947~3.176,P= 0.074)。结论GI-NEN恶�ObjectiveTo investigate the clinical characteristics, pathological classification and prognostic factors of gastrointestinal neuroendocrine neoplasms (GI-NENs) .MethodsClinicopathological data of 119 GI-NENs patients at Shanghai Renji Hospital from November 2007 to December 2016 were analyzed retrospectively. According to the classification and grading criteria of the WHO Neuroendocrine Tumor 2010 edition, patients were classified pathologically to realize the malignant degree of tumors. The overall survival rate was calculated by Kaplan-Meier curve, the prognostic risk factors were analyzed by Cox regression model, and the factors including the platelet/lymphocyte ratio (PLR) and neutrophil/lymphocyte ratio (NLR) were included in the analysis in addition to the routine clinicopathological factors.ResultsOf 119 patients with GI-NENs, there were 83 cases (69.7%) of male and 36 cases (30.3%) of female. The age of patients ranged from 24 to 86 (median 61) years. Tumor locations included the stomach (n= 70, 58.8%) , duodenum (n= 10, 8.4%) , small intestine (n= 2, 1.7%) , appendix (n= 3, 2.5%) , colon (n= 12, 10.1%) , and rectum (n= 22, 18.5%) . The tumor diameter was 0.6 to 20 cm, the mean diameter was 5.4 cm, and the median diameter was 4 cm. There were 25 cases of G1 neuroendocrine tumor (NET) , 7 cases of G2 NET and 87 cases of G3 neuroendocrine carcinoma (NEC) . Among the 119 patients, 113 cases (95%) had complete follow-up, and the median follow-up was 75 (1 to 112) months. The 5-years overall survival rate was 58.4%. The survival rate of G1 NET, G2 NET and G3 NEC were 100%, 71.4%, 44.4%, and the difference was statistically significant (P= 0.000) . Univariate analysis showed that age≥61 years (P= 0.000) , tumor located in the stomach, duodenum and colon (P= 0.041) , tumor size≥4 cm (P= 0.002) , pathology classification of G3 NEC (P= 0.000) , late TNM staging (P= 0.000) and blood PLR ≥133 (P= 0.017) were associated
