摘要 [目的]探讨鼻咽癌患者循环DNA含量与临床分期、疗效、预后之间的关系。[方法]对296例经病理证实的鼻咽癌患者治疗前抽取外周血,采用紫外分光光度计进行DNA含量的测定。其中103例于治疗结束后又进行了DNA含量测定。并以健康体检者77例作为对照组。[结果]鼻咽癌患者循环DNA含量(3746±401)μg/ml明显高于健康体检者(3348±394)μg/ml,P<0.05,治疗结束后循环DNA含量(3579±504)μg/ml明显下降,P<0.05。N3期含量(3898±384)μg/ml显著高于N0期(3684±349)μg/ml含量,P<0.05。循环DNA含量随着临床分期以及N分期增加而呈逐渐增高趋势,与T分期无关联。[结论]鼻咽癌患者循环DNA的定量分析有助于鼻咽癌的早期诊断、疗效判定、预后预测和复发的监控。
