摘要
目的探讨预后营养指数(prognostic nutritional index,PNI)对胃癌伴腹膜转移患者预后的意义。方法回顾性分析2010年1月至2016年12月间哈尔滨医科大学附属肿瘤医院收治的287例胃癌伴腹膜转移患者的临床病理资料。结果与PNI〉45组患者相比,PNI≤45组患者年龄较大[(59±11)岁比(54±11)岁,t=3.734,P=0.000]、血清白蛋白浓度低[(35±4)g/L比(42±4)g/L,t=15.988,P=0.003]、血红蛋白浓度低[(110±22)g/L比(129±24)g/L,t=6.245,P=0.000)、血小板与淋巴细胞比值大[(210±89)比(150±66),t=6.547,P=0.000]、中性粒细胞与淋巴细胞比值大(3.7±2.9)比(2.4±1.2),t=4.628,P=0.000]、姑息性胃切除的比例低(45.5%比58.5%X^2=4.45,P=0.035)。Logistic回归分析表明,年龄〉58岁、中性粒细胞与淋巴细胞比值〉2.87、血小板与淋巴细胞比值〉170、Hb≤130g/L、局部器官浸润均是导致PNI低的危险因素(均P〈0.05)。全组胃癌患者的中位生存时间仅为8.7个月。单因素分析结果显示:PNI〉45、血清白蛋白〉40g/L、无腹水、腹膜转移范围较小、姑息性胃切除、术后化疗的胃癌患者预后较好(均P〈0.05);多因素分析结果表明:PNI(HR=0.717,P=0.039)、腹膜转移分级(HR=1.206,P=0.044)、姑息性胃切除(HR=1.529.P=0.001)是影响胃癌患者预后的独立危险因素。结论PNI对于评估胃癌伴腹膜转移患者的营养状态和预后具有重要的临床意义。
Objective To evaluate the prognostic value of prognostic nutritional index (PNI) in gastric cancer patients with peritoneal metastasis. Methods 287 gastric cancer patients with peritoneal metastasis were enrolled from Jan 2010 to Dec 2016. Results Compared with PNI 〉 45, patients in PNI ≤ 45 group were elder [ ( 59±11 ) vs. ( 54±11 ), t = 3.734, P = 0. 000 ], lower albumin [ ( 35±4 ) g/L vs. ( 42 ± 4 ) g/L, t = 15. 988, P = 0. 003 ) ], lower plasm hemoglobin concentration [ (110±22 ) g/L vs. ( 129±24) g/L, t = 6. 245, P = 0. 000) , higher platelet count/lymphocyte count ratio [ PLR, (210±89) vs. (150±66 ), t = 6. 547, P = 0. 000], higher neutrophil count/lymphocyte count ratio [ NLR, ( 3.7±2. 9 ) vs. (2.4±1.2) , t = 4.628, P = 0. 000] , lower percentage of pallative gastrectomy (45.5% to 58.5% , X^2 =4. 45, P = 0. 035). Logistic regression analysis showed that age 〉 58-years, NLR 〉 2. 87, PLR 〉 170, hemoglobin ≤ 130 g/L, local organ infiltration were risk factors leading to low-PNI (all P 〈 0.05 ). The median survival time for all patients was 8.7 months. Univariate analysis revealed that, PNI 〉 45, serum albumin 〉 40 g/L, no ascites, lower-grade of peritoneal metastasis, pallative gastrectomy, postoperation chemotherapy were positively associated with better prognosis (all P 〈 0.05 ). Multivariate analysis demonstarted that, PNI ( HR=0.717, P=0.039). Grade of peritoneal metastasis ( HR = 1.206, P = 0.044) , pallative gastrectomy (HR = 1.529, P =0.001) were independent prognostic risk factors for the patients with peritoneal metastasis. Conclusion PNI are both predictors of nutrition assessment and of prognosis for gastric cancer patients with peritoneal metastasis.
