Acute Lymphoblastic Leukaemia (ALL) is the most common of childhood malignancies, representing 31% of all cancer cases in children younger than 15 years. In Germany, approximately 600 children are diagnosed with ALL each year. ALL is caused by the over-proliferation of lymphoid progenitor cells, arrested at early stages of B- or T-lymphocyte development. The disease can be classified into two different types: Common acute lymphoblastic leukaemia (B-ALL) and Acute Lymphoblastic Leukaemia (T-ALL). The two forms occur at different stages of lymphocyte development and in different cell lineages. In B-ALL, the tumour is derived from the B cell lineage and is caused by the over-proliferation of Pre- B cells. T-ALL is a malignancy of Thymocyte cells, which are progenitors for T lymphocytes (see Figure). B-ALL is more common than T-ALL representing 80-85% of all childhood ALL.


Treatment for ALL has markedly improved over the last 20 years, with modern chemotherapy treatments able to induce complete remission in 95-98% of children with the disease. However, approximately 20-30% of patients in remission have been found to later suffer a relapse, giving an overall survival rate of 80%. The relatively high rate of relapse means that patients in remission require careful monitoring to detect any indication of relapse. Most patients retain low levels of malignant cells, known as minimal residual disease (MRD), during and after cytotoxic treatment. It has been shown that levels of MRD significantly correlate with the probability of relapse in any particular patient i.e. that patients shown to have a high level of MRD have a higher risk of relapse than those with lower MRD levels. Therefore, measuring the levels of MRD can give a good indication of the treatment response and probability of relapse of any given patient.
