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
