摘要: 目的:探讨体内淋巴细胞微核形成与肺癌个体遗传易感性的关系。方法:本组病例- 对照研究包括95 例确诊肺癌患者和90 例对照。按末梢血微核法制备微核片。结果:肺癌患者的自发和吸烟诱发的微核率(MNF ,0187 ‰和1164 ‰) 比对照人群的(0147 ‰和0176 ‰) 有显著增加(分别P < 0. 05 和P < 0. 01) 。结论:肺癌患者是诱变效应易感人群;同时本研究首次证实,体内淋巴细胞微核形成是评价肺癌个体易感性的良好生物标志,MNF 为1 ‰和≥3 ‰的个体分别增加515 倍和2119 倍的发生肺癌的相对危险性。

Abstract: Purpose : To investigate the association of the in vivo micronucleus formation in lymphocytes of human peripheral blood with lung cancer. Methods : Case - cont rol study included 95 patient s with lung cancer and 90 cont rols. Slides were prepared by the in vivo micronucleus test in capillary blood lymphocytes. Results : Spontaneous and induced by smoking micronucleus f requencies (MNF) in lung cancer patient s ( 0. 87 ‰ and 1. 64 ‰) are significantly higher than those in cont rols(0. 47 ‰and 0. 76 ‰) ( P < 0. 05 and P < 0. 01) . Conclusion : Patient s with lung cancer were susceptible to mutagens ; In this study we confirmed first that the in vivo micronucleus formation in lymphocyte of peripheral blood is an excellent biomarker in assessing individual cancer susceptibility , persons with 1 ‰and 3 ‰of MNF had an increase of 5. 5 - fold and 21. 9 - fold higher relative risk for lung cancer.
