摘要:目的 分析产甲胎蛋白胃癌的临床病理学特征及预后影响因素,为临床诊断及治疗提供依据。方法 回顾分析1999年1月到2007年1月在广西医科大学附属第五医院住院的507例胃癌患者的病历资料,其中产甲胎蛋白胃癌(AFPGC)29例。详细记录AFPGC的临床病理及随访资料。采用SPSS 18.0统计软件包分析AFPGC的临床病理特征及影响预后的因素。结果 AFPGC占同期胃癌的5.7%,与普通胃癌相比,AFPGC具有较高的淋巴转移率、肝转移率,差异具有统计学意义(均P<0.05)。术前AFP水平偏高,肿瘤组织免疫组织化学检测显示原发病灶AFP染色强阳性,术后AFP有不同程度的降低或降至正常。生存分析发现产AFP胃癌患者的5年生存率低于普通胃癌,差异有统计学意义(P<0.05),单因素分析发现影响其预后的因素有肝转移、淋巴转移、TNM分期及分化程度。结论 产AFP胃癌具有易发生肝转移、淋巴转移且预后差的特点,早诊断、早治疗是目前提高治愈率和患者生存率的重要措施。

ital,Liuzhou 545006,ChinaAbstract Objective To analyze the clinicopathological features and prognostic factors of alpha-fetoprotein-producing 

gas-tric carcinoma(AFPGC).Methods From January 1999to January 2007,507cases of gastric cancer including 

29cases of AF-PGC were admitted to the Fifth Affiliated Hospital of Guangxi Medical University

,all the medical records were reviewed anddata on clinicopathological characteristic and follow-up were collected.The clinicopathological characteristics and prognostic fac-tors were evaluated by Chi-square test.The survival rate was calculated by Kaplan-

Meier method.Significance level was set at0.05.Statistical analyses were conducted using 

SPSS 18.0Statistical Package.Results The prevalence rate of AFPGC accoun-ted for 5.7%of the gastric cancer at the corresponding 

period.Compared with non-AFPGC,AFPGC had higher rate of lymphnode and liver metastasis(P<0.05).The level of preoperative serum AFP was normal,and immunohistochemistry 

showed thatthe AFP staining was strong positive at primary 

lesions.After operation,the serum level of AFP was reduced.Survival analysisshowed that 5-year survival rate of AFPGC was significantly 

lower than that of the non-AFPGC(P<0.05).Univariate analysisrevealed the prognostic factors included liver metastasis,lymph node metastasis,TNM stage,and grade of differentia-tion.Conclusion AFPGC is prone to proceed liver metastases,lymph node metastases and the prognosis is very poor.Early 

di-agnosis and early 

treatment are important measures to improve the curative rate and survival rate of the patients.Key 

words alpha-fetoprotein-producing gastric carcinoma; gastric tumor; pathological characteristics; prognosis 甲胎蛋白(alpha fetop

rotein,AFP)属于胚胎血清蛋白,主要由卵黄囊上皮、胚胎肝脏产生。病理情况下,AFP升高多见于原发性肝癌、肝硬化、急性肝炎等疾病。源于内胚层器官的肿瘤如胃肠癌、胰腺癌、

胆囊癌、肺癌,以及非内胚层肿瘤如乳腺癌和个别其他系统肿瘤也偶见AFP升高[1]。产甲胎蛋白胃癌(alpha-fetoprotein-producing 

gastric carcino-ma,AFPGC)

是指患者血清和癌组织中含有大量AFP的胃癌。1970年,Bourreille等[2]

首次报道

AFPGC,

自此,国外学者陆续报道一些胃肠道肿瘤可产生AFP[3-5]

。据报道,AFPGC的发生率占同期

胃癌的2.7%~8.0%[6],

具有高度肝脏转移倾向性、分化程度低、恶性度高、预后差等特点。本研究回顾了广西医科大学第五附属医院确诊并完成治疗的29例AFPGC患者的临床资料,分析其病理学特征及预后情况。1 资料和方法
