摘要: 目的: 通过对恶性肿瘤患者的癌组织细胞及其外周血淋巴细胞进行抗肿瘤药物的体外诱导,用RT2PCR 法检测其mdr-1 基因表达状况,从而找出两者之间的相关性,从基因水平解决非手术癌患者化疗用药个体化。方法:在采集手术标本的同时抽取该患者外周血,用8 种抗肿瘤药物进行体外诱导,RT-PCR 法检测32 例恶性肿瘤患者癌组织细胞及其外周血淋巴细胞的mdr-1 基因表达状况。利用SAS 软件计算两者之间的相关关系。结果:32 例恶性肿瘤患者的新鲜癌组织细胞与其外周血淋巴细胞的抗肿瘤药物体外诱导mdr-1 基因表达呈正相关关系。结论:对于失去手术机会或病灶很小不能取材的患者可以用外周血淋巴细胞替代癌细胞做RT-PCR 体外药敏检测。这将从基因水平为肿瘤患者个体化用药提供一个新的途径。

Abstract: Purpose : To investigate the relativity of mdr-1 expression between the f resh tumour cells and the peripheral lymphocytes of 32 patients with malignant tumours. Methods : Using reverse t ranscription2polymerase chain reaction (RT-PCR) assay , mdr-1 expression induced by 8 anticancer drugs in the f resh tumour cells and the peripheral lymphocytes of 32 patients with malignant tumours was detected. Results : There was a positive relativity of mdr21 expression between the fresh tumour cells and the lymphocytes. Conclution : The lymphocytes of peripheral blood can replace tumour cells in selecting sensitive drugs with RT-PCR assay invit ro. It can provide a new way of using drug individually for patients with malignant tumours.

Key words: tumour cell, lymphocyte, RT-PCR, mdr-1
