目的:检测胰腺癌中错配修复基因 hMLH1、hMLH2表达情况,研究其与胰腺癌临床特征的关系,并探讨其与胰腺癌手术治疗预后的相关性。方法免疫组织化学法检测58例胰腺癌组织、24例正常胰腺组织中 hMLH1、hMLH2表达,结合临床病理资料及随访资料进行统计学分析。结果58例胰腺癌组织中 hMLH1、hMLH2阳性表达率分别为43%(25/58)、38%(22/58),均低于24例正常胰腺组织中 hMLH1、hMLH2阳性表达率92%(22/24)、83%(20/24),且差异均有统计学意义(P 值均为0.000)。不同年龄、性别、肿瘤直径的胰腺癌组织 hMLH1、hMLH2阳性表达率差异均无统计学意义(hMLH1:P 值分别为0.849、0.971、0.778、0.894;hMLH2:P 值分别为0.790、0.837、0.670、0.971),不同分化程度、有无淋巴结转移的胰腺癌组织 hMLH1、hMLH2阳性表达率差异均有统计学意义(hMLH1:P 值分别为0.018、0.007;hMLH2:P 值分别为0.029、0.006)。21例 hMLH1阳性表达、23例 hMLH2阳性表达的胰腺癌患者术后2年生存率分别为43%(9/21)、48%(11/23),分别高于17例 hMLH1阴性表达、15例 hMLH2阴性表达的胰腺癌患者术后2年生存率24%(4/17)、13%(2/15),且差异均有统计学意义(P 值分别为0.013、0.002)。结论 hMLH1、hMLH2在胰腺癌中的失表达在肿瘤的发生、发展及转移中起重要作用,是判断胰腺癌手术治疗预后有价值的指标。
目的:檢測胰腺癌中錯配脩複基因 hMLH1、hMLH2錶達情況,研究其與胰腺癌臨床特徵的關繫,併探討其與胰腺癌手術治療預後的相關性。方法免疫組織化學法檢測58例胰腺癌組織、24例正常胰腺組織中 hMLH1、hMLH2錶達,結閤臨床病理資料及隨訪資料進行統計學分析。結果58例胰腺癌組織中 hMLH1、hMLH2暘性錶達率分彆為43%(25/58)、38%(22/58),均低于24例正常胰腺組織中 hMLH1、hMLH2暘性錶達率92%(22/24)、83%(20/24),且差異均有統計學意義(P 值均為0.000)。不同年齡、性彆、腫瘤直徑的胰腺癌組織 hMLH1、hMLH2暘性錶達率差異均無統計學意義(hMLH1:P 值分彆為0.849、0.971、0.778、0.894;hMLH2:P 值分彆為0.790、0.837、0.670、0.971),不同分化程度、有無淋巴結轉移的胰腺癌組織 hMLH1、hMLH2暘性錶達率差異均有統計學意義(hMLH1:P 值分彆為0.018、0.007;hMLH2:P 值分彆為0.029、0.006)。21例 hMLH1暘性錶達、23例 hMLH2暘性錶達的胰腺癌患者術後2年生存率分彆為43%(9/21)、48%(11/23),分彆高于17例 hMLH1陰性錶達、15例 hMLH2陰性錶達的胰腺癌患者術後2年生存率24%(4/17)、13%(2/15),且差異均有統計學意義(P 值分彆為0.013、0.002)。結論 hMLH1、hMLH2在胰腺癌中的失錶達在腫瘤的髮生、髮展及轉移中起重要作用,是判斷胰腺癌手術治療預後有價值的指標。

Objective To investigate the expressions of hMLH1 ,hMLH2 and the relationship with the clinical features of pancreatic cancer and the correlation with prognosis after surgery.Methods In 58 specimens of pancreatic cancer,24 specimens of normal pancreas tissues,the expressions of hMLH1 ,hMLH2 were detected by immunohistochemistry methods.Laboratory data were then analysed statistically together with the related clinical-pathological data.Results The positive expression rates of hMLH1 and hMLH2 were 43%(25 /58)and 38% (22 /58)in pancreatic cancer tissues,and were 92% (22 /24)and 83% (20 /24)in normal pancreatic tissues.The expressions of hMLH1 and hMLH2 in pancreatic cancer were obviously reduced,and the differences had significance (all P =0.000).The expressions of hMLH1 and hMLH2 in pancreatic cancer had no association with age,gender and tumor size (hMLH1 :P value was 0.849,0.971 , 0.778,0.894 respectively;hMLH2:P value was 0.790,0.837,0.670,0.971 respectively),but the expressions were closely related with differentiated degree and lymph node metastasis (hMLH1 :P value was 0.01 8,0.007 respectively;hMLH2:P value was 0.029,0.006 respectively).The 2-year-survival rate of hMLH1 -negative patients was significantly lower than that of hMLH1 -positive patients after radical operation [24%(4/17)vs 43% (9 /21 ),P =0.01 3 ].The 2-year-survival rate of hMLH2-negative patients was significantly lower than that of hMLH2-positive patients after radical operation [1 3% (2 /15 ) vs 48%(11 /23),P =0.002].Conclusion Joint action of hMLH1 ,hMLH2 plays an important role in the oncogenesis,development and metastasis of pancreatic cancer,and hMLH1 ,hMLH2 may be the valuable indicator for prognosis.
