There are more than hundred varieties of blood cancer, but the most common ones are leukemia, lymphoma, and myeloma. Acute myeloid leukemia (AML), a type of leukemia, is when the white blood cells in the marrow begin to grow uncontrollably. This is an acute condition and both the onset and progress are very rapid. The cause is not known, and given the rapid progress, even treatment is often difficult. A more severe form of AML is the APML which is acute promyelocytic leukemia, which leads to reduced number of white and red blood cells and plasma.
This causes the following symptoms:
What is different about APML?
There is one distinguishing factor with APML, which is that they contain a protein which when released into the bloodstream can cause severe bleeding, which may be very difficult to control. Chemotherapy kills these cells and so releases the proteins into the bloodstream. These cells need to be managed without chemotherapy, as the patient can even die of uncontrolled bleeding. With medical advances, two non-chemotherapy agents have been identified – all-trans retinoic acid (ATRA, vesanoid, or tretinoin) and arsenic trioxide (ATO or trisenox).
With both these drugs, there is a significant side effect, known as differentiation syndrome - symptoms include fever, breathing difficulty. Often seen during the first cycle of treatment, this happens when the leukemia cells release a protein into the blood. Symptoms include fever, breathing, kidney damage, and severe fluid buildup. With these two drugs being widely used effectively, chemotherapy is not the only treatment option for APML.
