摘要 目的:研究RAR-βmRNA在食管癌发生发展过程中的作用,探讨维A酸(RA,retinoid acid)在食管癌高危人群中化学预防和化学治疗中应用的可行性. 方法:应用原位杂交方法检测了食管癌70例(原位癌30 例,鳞状细胞癌20例,腺癌20例)及增生性病变97例(单纯增生19例,不典型增生Ⅰ-Ⅲ分别为20例,39例,38 例)和正常食管黏膜鳞状上皮组织19例中RAR-βmRNA表达情况. 结果:在正常食管黏膜上皮、单纯增生、不典型增生上皮总体及其Ⅰ-Ⅲ、原位癌、侵袭性鳞状细胞癌及腺癌中RAR-βmRNA表达的阳性率分别为100%(19/19),94.7% (18/19),90%(18/20),69.2%(27/39),68.4%(26/38), 63.3%(19/30),60%(12/20),60%(12/20).正常食管黏膜上皮较不典型增生总体、原位癌和侵袭癌组织均有显著性差异(P<0.05). 结论:RAR-βmRNA表达的丢失与食管癌的发生发展有关, 用RA对表达RAR-β高危人群进行化学干预可能会得到预期效果.
