摘要:

目的 探讨唾液腺粘液表皮样癌耐药性产生的机制,以便有针对性地采取逆转措施提高综合治疗中化疗的效果。方法 选取四川大学华西口腔医院口腔颌面外科1995~2000年40例术前未经任何治疗的唾液腺粘液表皮样癌标本,采用免疫组化ABC法,进行P-gp单克隆抗体JSB-1的检测,同时对其中10例进行了GST-π的检测。结果 JSB-1表达阳性率为67·5%(27/40),与分化程度相关,高分化组和中分化组均高于低分化组(P<0·05),高分化组和中分化组之间无统计学差异(P>0·05)。GST-π表达阳性率为90%(9/10)。两种抗体的表达在唾液腺粘液表皮样癌组织中的表达无统计学差异,亦无相关性。结论 JSB-1及GST-π与唾液腺粘液表皮样癌产生耐药的机制有关,为开展其耐药性的研究提供了靶标。

Abstract:

Objective The aim of this studywas to investigate the mechanism(MDR) ofmultidrug resistance(MDR) ofmucoe- pidermoid carcinoma in salivary gland.Methods 40 cases of mucoepidermoid carcinoma in salivary gland were examined the MDR gene product P-glycoprotein using a monoclonal antibody JSB-1. And 10 of themwere also investigated by detecting the ex- pression of GST-π. All the cases had not been accepted any therapy before the samples were collected.Results ①Positive ex- pression of JSB-1 was observed in 27 of the 40 specimens. The positive expressionwas related not onlywith clinical stage, but also with differentiation degree.②The GST-πpositive expressionwas found in 9 of 10 cases. Therewas no significant different between the positive expression of JSB-1 and GST-π.Conclusion JSB-1 and GST-πplay an important role in MDR of mucoepidermoid carcinoma.
