目的 探讨肿瘤转移抑制蛋白(MTSS1)与上皮型钙黏蛋白(E-cadherin)在上尿路移行上皮癌中的表达情况及意义.方法 收集病理科存档的60例上尿路移行上皮癌石蜡标本为观察组,同时取其中30例患者的膀胱正常组织作为对照组.采用免疫组织化学方法检测组织中MTSS1及E-cadherin的表达情况,并分析其表达与不同病理分期、分化程度及淋巴结转移间的关系.结果 MTSS1在对照组的表达率为100.0% (30/30),在观察组表达率为45.0%(27/60),两组比较差异有统计学意义(P<0.05);E-cadherin在对照组表达率为96.7%(29/30),在观察组表达率为41.7%(25/60),两组比较差异有统计学意义(P<0.05);MTSS1与E-cadherin在不同病理分期、分化程度及淋巴结有无转移中表达率差异有统计学意义,分化程度好、TNM分期低、淋巴结无转移的患者中MTSS1与E-cadherin的表达率较高(P<0.05);MTSS1与E-cadherin在癌组织中的表达并无相关性(P>0.05).结论 在上尿路移行上皮癌中联合检测MTSS1及E-cadherin的表达,对于判断肿瘤的恶性程度、淋巴结转移情况及患者的预后均有重要意义.
目的 探討腫瘤轉移抑製蛋白(MTSS1)與上皮型鈣黏蛋白(E-cadherin)在上尿路移行上皮癌中的錶達情況及意義.方法 收集病理科存檔的60例上尿路移行上皮癌石蠟標本為觀察組,同時取其中30例患者的膀胱正常組織作為對照組.採用免疫組織化學方法檢測組織中MTSS1及E-cadherin的錶達情況,併分析其錶達與不同病理分期、分化程度及淋巴結轉移間的關繫.結果 MTSS1在對照組的錶達率為100.0% (30/30),在觀察組錶達率為45.0%(27/60),兩組比較差異有統計學意義(P<0.05);E-cadherin在對照組錶達率為96.7%(29/30),在觀察組錶達率為41.7%(25/60),兩組比較差異有統計學意義(P<0.05);MTSS1與E-cadherin在不同病理分期、分化程度及淋巴結有無轉移中錶達率差異有統計學意義,分化程度好、TNM分期低、淋巴結無轉移的患者中MTSS1與E-cadherin的錶達率較高(P<0.05);MTSS1與E-cadherin在癌組織中的錶達併無相關性(P>0.05).結論 在上尿路移行上皮癌中聯閤檢測MTSS1及E-cadherin的錶達,對于判斷腫瘤的噁性程度、淋巴結轉移情況及患者的預後均有重要意義.

Objective To investigate the significance of MTSS1 and E-cadherin expression in upper urinary tract transitional epithelial carcinoma.Methods Paraffin specimens of 60 patients with upper urinary tract transitional epithelial carcinoma between January 2005 and January 2014 were analyzed.At the same time,5 cm normal tissue adjacent to the cancerous tissue specimens in 30 patients were taken for comparison.Immunohistochemical method was used to detect the tissue MTSS1 and E-cadherin expression,and the relationships between their expression with different pathological stage,differentiated degree and lymph node metastasis were analyzed.Results MTSS1 expression rate in normal tissue (100.0%,30/30) was significantly higher than that in cancerous tissue (45.0%,27/60) and there was significant difference (P < 0.05).E-cadherin expression rate in normal tissue (96.7%,29/30) was significantly higher than that in cancerous tissue (41.7%,25/60) and there was significant difference (P < 0.05).The expression of MTSS1 and E-cadherin in different pathological stage,degree and with or without lymph node metastasis had significant difference (P < 0.05).In patients with well differentiated,low TNM stage and no lymph metastasis,MTSS1 and E-cadherin expression rate was higher (P < 0.05).There was no significant correlation between the expression of MTSS 1 and E-cadherin in cancerous tissue (P > 0.05).Conclusion In upper urinary tract transitional cell carcinoma detection of both MTSS1 and E-cadherin has important significance with regards to judging the malignant degree of the tumor,lymph node metastasis and prognosis in patients.
