摘要(Abstract):
目的:研究卵巢癌细胞凋亡、相关基因表达及其与化疗的关系。方法:选择卵巢上皮性癌32例,行初次手术后给予以铂类为基础的联合化疗4 疗程以上,19 例行二次手术。对2 次手术标本分别作细胞凋亡原位检测和凋亡指数(AI)计数,细胞核增殖抗原(PCNA)、P53和Bcl2 基因表达免疫组化染色。结果:化疗有效组AI显著高于无效组(t= 3.16,P< 0.05),化疗前AI显著高于化疗后(t= 2.28,P< 0.05),高AI组(AI≥2.0)存活例数显著高于低AI组(AI< 2.0)(χ2 = 6.42,P< 0.05),平均生存期长于低AI组,但差异无显著性(t= 1.13,P> 0.05),AI和PCNA变化无显著关系(t= 0.64,P> 0.05),高AI组伴有高P53和高Bcl2 表达趋势,但未达显著性水平(t= 0.48,P> 0.05 和t= 0.77,P> 0.05)。结论:卵巢癌对化疗的效应与凋亡有关,高AI者敏感性较高,且预后良好,凋亡过程可能受P53和Bcl2 基因调控。AI检测可作为预测卵巢癌对化疗的效应和预后的指标。
