目的:探讨结直肠癌不同发病部位的临床病理及分子特征的差异。方法对2005—2013年就诊于上海某肿瘤医院4316例结直肠癌患者的临床病理特征和2224例结直肠癌患者分子标记的免疫组化结果进行统计分析。临床病理特征包括年龄、性别、肿瘤分型、组织类型、分化程度、肿瘤病理T分期,免疫组化结果包括人错配修复基因1(hMLH1)、人错配修复基因2(hMSH2)、CD44抗原(CD44)、周期素依赖激酶抑制子1(p21)、肿瘤蛋白p53(p53)、环氧化酶2(COX2)、E-钙黏蛋白(E-cadherin)、人类表皮生长因子受体2(Her2)和细胞增殖核抗原(Ki-67)。结果右半结肠癌与左半结肠癌和直肠癌相比,女性右半结肠癌患病率较高[构成比分别为46.0%(541/1176);39.2%(424/1083);41.2%(848/2057),χ2=11.85,P<0.01],黏液腺癌和印戒细胞癌比例更大[构成比分别为12.0%(128/1064),5.8%(56/960),4.0%(75/1859),χ2=70.93,P<0.01],分化更差[构成比分别为32.1%(343/1069),19.5%(201/1033),19.3%(380/1967),χ2=72.66,P<0.01],肿瘤分期更晚[构成比分别为87.9%(992/1129),83.2%(869/1045),72.2%(1486/2057),χ2=121.44,P<0.01]。免疫组化结果显示,右半结肠癌患者hMLH1和hMSH2表达阴性率比直肠癌高[13.4%(59/439)比8.5%(88/1035),OR(95%CI):1.67(1.18~2.37);4.9%(22/452)比2.4%(26/1083),OR(95%CI):2.08(1.17~3.71)],p53表达阳性率较直肠癌高[76.2%(321/421)比68.4%(776/1134),OR(95%CI):0.68(0.52~0.87)];而直肠癌患者Her2表达阳性率较右半结肠癌高[19.3%(176/913)比13.2%(45/340),OR(95%CI):1.57(1.10~2.23)],Ki-67表达阳性细胞大于等于50%的患者比例较右半结肠癌高[73.6%(840/1141)比65.6%(299/456), OR (95%CI ):0.68(0.54~0.86)]。结论右半结肠癌的临床病理特征有其特殊性,右半结肠癌和直肠癌之间分子特征差异明显。

Objective To investigate the differences of clinical characteristics and molecular features among colorectal cancer subsides and provide evidence for colorectal cancer protection,diagnosis and treatment.Methods All of 4 316 colorectal patients from Shanghai cancer center were selected for clinical character analysis, among which, 2 224 subjects for molecular feature analysis.Clinic pathological characteristics like age, gender, tumor types, histological types, differentiation and T-stage, as well as molecular features like hMLH1,hMSH2,CD44,p21,p53,COX2,E-cadherin,Her2 and Ki-67,were involved into this research.Results It showed that compared with left-sided colon and rectal cancers, right-sided cancers occurred more in women ( 46.0% ( 541/1 176 ); 39.2% ( 424/1 083 ); 41.2% ( 848/2 057 ) , respectively,χ2 =11.85,P<0.01), had more mucinous or signet-ring carcinoma(12.0%(128/1 064), 5.8%(56/960),4.0%(75/1 859),respectively,χ2 =31.27,P <0.01), poor differentiated carcinoma (32.1%(343/1 069),19.5%(201/1 033), 19.3%(380/1 967),respectively,χ2 =72.66,P<0.01), and advanced T stage(87.9%(992/1 129), 83.2%(869/1 045), 72.2%(1 486/2 057),respectively,χ2 =121.44,P <0.01).Meanwhile,the rates of hMLH1 were higher in right-sided colon cancers when compared with rectal cancers ( 13.4% ( 59/439 ) vs 8.5% ( 88/1 035 ) , OR ( 95%CI ): 1.67 ( 1.18-2.37)),as well as the rates of hMSH2 negative expression(4.9% (22/452) vs 2.4% (26/1 083),OR (95%CI):2.08(1.17-3.71)).The rates of p53 positive expression were higher in right-sided colon cancers when compared with rectal cancers ( 76.2% ( 321/421 ) vs 68.4%, ( 776/1 134 ) , OR ( 95%CI ): 0.68 (0.52-0.87)).Compared with right-sided colon cancers,the rates of Her2 positive expression were higher in rectal cancers(19.3%(176/913) vs 13.2% (45/340),OR(95%CI):1.57 (1.10-2.23)),as well as the rates of Ki-67 expression which was positive in more than 50%cells (73.6%(840/1 141) vs 65.6%(299/456),OR(95%CI):0.68 (0.54-0.86)).Conclusion There are specific characteristics in right-sided colon cancers.The difference of molecular features between right-sided colon and rectal cancers are more significant.
