Leukaemias are classified according to the speed of disease progression (acute, chronic) and the cell type from which they originate (myeloid, lymphatic).

The four most common forms of leukaemia are:

  • Acute myeloid leukaemia (AML)
  • Chronic myeloid leukaemia (CML)
  • Acute lymphatic leukaemia (ALL)
  • Chronic lymphocytic leukaemia (CLL)

In addition to these four main types, there are several other forms of leukaemia, but they are rare.

Frequency of leukaemias

In 2017, approximately 13,895 people in Germany were diagnosed with leukaemia, 4 percent of whom were under 15 years of age. The risk of developing leukaemia decreases in children and young adults with increasing age. At the age of 30 years, risk begins to increase again, with a higher incidence rate in men compared to women. One in 67 men and one in 87 women will develop leukaemia during their lifetimes.

Between 1999 and 2016, age-standardised incidence rates remained relatively stable, while age-standardised mortality rates declined. About 38 percent of newly diagnosed cases were chronic lymphocytic leukaemia (CLL) and about 23 percent acute myeloid leukaemia (AML).

The prognosis for people with leukaemia depends on the form of the disease and the age at diagnosis: People diagnosed in childhood have by far the best chances of survival, whereas the acute forms of the disease in adults still have a rather poor prognosis. Overall, just over a third of adults with leukaemia are still alive 10 years after diagnosis. In the case of chronic leukaemia, a cure, e.g. by means of a high-risk stem cell transplant, is seldom possible.

Ionising radiation increases the risk of leukaemia

No risk factor has been identified that affects all types of leukaemia. However, some factors increase the risk of developing certain leukaemias. Among the known risk factors for acute leukaemias are ionizing radiation and cytostatic drugs. Occupational exposure to benzene, 1,3-butadiene and related substances can also contribute to the development of leukaemia. Some rare genetic alterations can increase the risk of acute leukaemia, including trisomy of chromosome 21. Viruses have not been confirmed as a risk factor for leukaemia, with the exception of the human T-lymphotropic virus (HTLV), which is extremely rare in Europe. Several other risk factors are currently being discussed as causes of leukaemia. These include environmental influences as well as lifestyle factors such as smoking or excess body weight. However, a connection has not yet been proven.

For most patients with leukaemia, no clear cause can be found. It is likely that several factors must work together.
