[摘 要] 目的:探讨胃癌患者血常规指标的异常特征,并分析其随病程的变化趋势。方法:本研究对象为2020年8月—2021年
12月参加无锡市太湖肿瘤标志物队列(the Taihu Biobank of Tumour Biomarkers,TBTB)的人群,选取基线1 920例已患有胃癌者
为胃癌组,并按照年龄、性别以1∶4的比例匹配7 680例未患癌症者为对照组。采用多元线性回归模型探讨血常规检测指标与
胃癌患病情况之间的关联,并采用Kruskal⁃Wallis H检验比较不同病程间血常规相关指标的差异。结果:多元线性回归模型显
示,胃癌患者的贫血相关指标:血红蛋白(hemoglobin,HGB)、血小板计数(platelet count,PLT)、红细胞计数(red blood cell count,
RBC)、白细胞计数(white blood cell count,WBC)、平均血红蛋白含量(mean corpuscular hemoglobin,MCH)、平均红细胞血红蛋白
浓度(mean corpuscular hemoglobin concentration,MCHC)水平均显著低于对照组,其中以 HGB 下降最为显著(β=-0.78,
95%CI:-0.83~-0.73,P < 0.001)。此外,红细胞分布宽度(red blood cell volume distribution width,RDW)(β=0.13,95% CI:0.08~
0.17,P < 0.001)和红细胞比容(hematocrit,HCT)(β=0.16,95% CI:0.10~0.22,P < 0.001)水平显著高于对照组,提示胃癌患者易
出现贫血相关征象。病程分析表明,WBC随胃癌患者病程延长呈现逐渐减少的趋势(P < 0.001),HGB、RBC和HCT虽呈增高
趋势(P均< 0.001),但仍低于对照组。结论:本研究表明,胃癌患者相比健康对照人群更易出现贫血相关征象,部分血常规指
标随病程延长呈显著变化趋势,为胃癌的临床监测提供了重要参考。

[Abstract] Objective:To investigate the abnormalities in routine blood parameters among gastric cancer patients and analyze their
trends over the course of the disease. Methods:This study included the population who participated in the Taihu Tumour Biomarkers
Biobank(TBTB)in Wuxi from August 2020 to December 2021,with 1 920 cases who already had gastric cancer at baseline as the
gastric cancer group and 7 680 cancer⁃free cases matched 1∶4 for age and sex as the healthy control group. A study design was adopted
to explore the association between routine blood tests and the prevalence of gastric cancer using multiple linear regression model,and
the Kruskal⁃Wallis H test was further used to compare the differences in routine blood tests across different stages of the disease
between groups. Results:Multiple linear regression model showed that levels of hemoglobin(HGB),platelet count(PLT),red blood
cell count(RBC),white blood cell count(WBC),mean hemoglobin content(MCH)and mean corpuscular hemoglobin concentration
(MCHC)were lower in gastric cancer patients than in controls,with HGB levels decreasing the most(β=-0.78,95% CI:-0.83--0.73,
P < 0.001),and red blood cell volume distribution width(RDW)(β=0.13,95% CI:0.08-0.17,P < 0.001)and hematocrit(HCT)(β=
0.16,95% CI:0.10-0.22,P < 0.001)levels were higher than those of the control group,suggesting that anemia⁃related signs were more
