2.MRD cells were quantitated at inductioncomplete remission (CR)in 14 cases whose untreated samples were positive. The averageamount of MRD cells was 0. 343% in marrow relapse group and 0. 004% in non-relapsegroup (P<0. 01).
3.It is concluded that the detection of APL patients by means of two sets of antibody panels is simple and suitable, which is complementary to PCR in monitoring MRD of APL patients.
