[M-FISH technique in diagnosis and prognostic analysis for acute leukemia with complex chromosomal aberrations].
The M-FISH includes multi-colour FISH and multiplex FISH, it represents one of the most significant developments in molecular cytogenetics of the past decade. This technique was originally designed to generate 24 colour karyotyping in human's 23 pair chromosome, now the technique has many variations and has been used in different fields. In leukaemia cytogenetics, the M-FISH now is used in detection for AL patients with following chromosome abnormality: (1) harbouring minimal chromosome translocation is respected; (2) chromosome translocation with complex abnormal karyotypes exists in patients with leukemia which are difficulty detected by using conventional method. The final results detected by M-FISH have guide significance for diagnosis, therapy and prognosis of AL patients. In this article the technical basis with commonly used probe for M-FISH, application of M-FISH in diagnosis, evaluation of therapeutic efficacy and prognostic analysis of AL patients are summarised.
