title: The use of genetic microarray analysis to classify and predict prognosis in haematological malignancies.
abstract: The introduction of microarrays offers the opportunity to examine the expression of many thousands of genes in a single experiment. Investigations in leukaemia and lymphoma have led to the identification of a number of subgroups, with a defined gene expression pattern, not previously identified by morphology, cytogenetics or molecular techniques. In many cases these expression patterns can be linked to the tumour cells normal developmental counterpart, and represent distinct disease subgroups with different clinical presentations and outcomes. The technology has also identified genes that may be important in tumour cell biology including key genes in cell proliferation, adhesion, apoptosis, and the development of drug resistance. These early studies demonstrate that genetic microarrays will be useful in classifying haematological malignancies, predicting response to treatment, predicting prognosis, and identifying novel targets for therapy.
