目的 :探讨高、低发区人群贲门癌变过程中表皮生长因子受体 (EGFR)表达与病变发生发展的生物学意义。方法 :采用免疫组织化学方法 (ABC法 ) ,检测高 (133例 )、低发区 (14 2例 )居民贲门上皮不同程度病变的EGFR变化特征及其与病变的关... 目的 :探讨高、低发区人群贲门癌变过程中表皮生长因子受体 (EGFR)表达与病变发生发展的生物学意义。方法 :采用免疫组织化学方法 (ABC法 ) ,检测高 (133例 )、低发区 (14 2例 )居民贲门上皮不同程度病变的EGFR变化特征及其与病变的关系。结果 :在贲门癌高发区 ,随贲门上皮病变进展 ,慢性浅表性胃炎 (CSG)→慢性萎缩性胃炎 (CAG)→不典型增生 (DYS)→贲门腺癌 (GCA) ,EGFR蛋白阳性率分别为 4 3%、4 4 %、79%和 5 3% ;DYS组EGFR蛋白阳性率与其它各组比较差异有统计学意义 (P值均 <0 .0 5 ) ;EGFR蛋白表达阳性率随贲门癌分化程度降低而减低 ,但无统计学意义。在贲门癌低发区 ,随贲门上皮病变加重 ,EGFR蛋白阳性率呈明显上升趋势 ,从CSG→CAG→DYS→GCA ,EGFR蛋白阳性率分别为 16 %、2 7%、5 0 %和 4 6 % ;正常贲门组织 (NOR)、CSG与GCA ,NOR、CSG与DYS比较差异均有统计学意义 (P值均 <0 .0 5 )。EGFR蛋白表达阳性率不随贲门癌分化程度降低而改变。结论 :EGFR是贲门上皮癌变 ,特别是早期病变的重要分子变化。高、低发区贲门癌变可能存在不同的分子基础 ,环境中暴露的致癌因素不同 (质和量 ) 展开更多

OBJECTIVE To retrospectively analyze clinical data of patientsfrom our hospital who underwent radical surgery for esophagealcarcinoma and for adenocarcinoma of the gastric cardia,as well asto investigate prognostic factors affecting the long-term survival ofthe patients.METHODS Data from the patients eligible for our study,admitted to the 4th Hospital of Hebei Medical University fromJanuary 1996 to December 2004,were randomized,and 12distinctive clinicopathologic factors influencing the survival rateof those who underwent radical surgery for esophageal carcinomaor carcinoma of the gastric cardia were collected.Univariate andmultivariate analysis of these individual variables were performedusing the Cox proportional hazard model.RESULTS It was shown by univariate analysis that age,tumorsize,pathologic type,lymph node status,TNM staging,depthof infiltration and encroachment into local organs,etc.,were thefactors that markedly influenced the prognosis of patients(P<0.01).Multivariate analysis showed that pathologic type,numberof the lymph node metastases,involvement of local organs,andTNM staging were independent prognostic factors(P<0.05).CONCLUSION The independent factors influencing theprognosis of patients with esophageal cancer and carcinoma ofthe gastric cardia include pathologic type,number of lymph nodemetastases,involvement of local organs and TNM staging.Themain prognostic factors affecting the patient's survival are patientage,tumor size and depth of infiltration.In addition,patients withinvolvement of the local organs have a worse prognosis,and theyshould be closely followed up. 展开更多
