The prognosis for 15-year-olds diagnosed with leukemia varies depending on the type of leukemia and the individual's overall health. However, generally speaking, the overall 5-year survival rate for 15-year-olds diagnosed with leukemia is around 65%. That means that, on average, about 65% of 15-year-olds diagnosed with leukemia are expected to live at least 5 years after diagnosis.
The prognosis for 15-year-olds with acute lymphoblastic leukemia (ALL) is generally better than the prognosis for those with acute myeloid leukemia (AML). For 15-year-olds with ALL, the 5-year survival rate is about 80%. For 15-year-olds with AML, the 5-year survival rate is closer to 50%.
It is important to remember that the prognosis for each individual patient will depend on a variety of factors, including the type of leukemia, the patient's overall health, the stage of the disease, and the response to treatment. For many patients, a combination of chemotherapy and other treatments can be very successful in treating the disease, and may lead to long-term survival.
