Leukemia Home > Sprycel Uses
Sprycel is prescribed to treat certain types of cancer that affect the blood and bone marrow. Specifically, Sprycel is used for the treatment of chronic myeloid leukemia and acute lymphoblastic leukemia. It is approved only for use in people age 18 and older. In some cases, this drug may be used off-label for several purposes, such as prostate cancer and cancer of the digestive tract.
What Is Sprycel Used For?Sprycel® (dasatinib) is a prescription chemotherapy medication approved to treat certain types of leukemia, a cancer of the blood and bone marrow. Leukemia occurs when the bone marrow (the tissue in the middle of bones that makes blood cells) produces a large amount of abnormal blood cells. These abnormal blood cells grow out of control and eventually crowd out normal, healthy blood cells.
There are several different types of leukemia. The types are generally named for how quickly the disease progresses (chronic versus acute), and which blood cells are affected (lymphoid versus myeloid). Treatment will vary, mainly depending on the type of leukemia a person has. Sprycel is approved to treat chronic myeloid leukemia (CML) and acute lymphoblastic leukemia (ALL).
Chronic Myeloid LeukemiaChronic myeloid leukemia (sometimes called chronic myelogenous leukemia) is a slowly progressing leukemia in which bone marrow stem cells (the early cells that form blood cells) develop into many abnormal granulocytes (a type of white blood cell). Some of these cells never become mature white blood cells. These are called blasts. Over time, the granulocytes and blasts crowd out the red blood cells and platelets in the bone marrow.
CML generally progresses through three phases, or stages. These three stages include:
- Chronic phase
- Accelerated phase
- Blast phase.
Most people are diagnosed in the chronic phase. In this phase, symptoms are usually mild or not present. As the number of leukemia cells increases, the disease moves into the accelerated phase, and eventually the blast phase. In the blast phase, CML acts much like acute leukemia and symptoms may be quite significant.
The majority of people with CML have an abnormal chromosome called the Philadelphia chromosome (Ph chromosome). Sprycel is approved for people who are newly diagnosed with Ph chromosome-positive CML in the chronic phase. It is also approved for people who have Ph chromosome-positive CML in any phase, when other treatments did not work or could not be used.
