APL is a rare sub-type of acute myeloid leukaemia (AML). When you have APL, the bone marrow is not able to make enough normal blood cells. APL is treated in a very different way from other forms of AML, if a patient with APL is given standard treatment, there is a risk of serious problems with their clotting system.
Acute promyelocytic leukemia (APL) is a unique subtype of acute myeloid leukemia (AML) in which cells in the bone marrow that produce blood cells (red cells, white cells and platelets) do not develop and function normally. In APL, promyelocytes (immature white cells) are overproduced and accumulate in the bone marrow.
Beside above, what stage is acute myeloid leukemia? Undifferentiated AML – M0: In this stage of acute myelogenous leukemia, the bone marrow cells show no significant signs of differentiation. Myeloblastic leukemia – M1: Bone marrow cells show some signs of granulocytic differentiation with or without minimal cell maturation.

What are the symptoms of acute promyelocytic leukemia?
- Bleeding that is hard to stop, even from a small cut.
- Blood in the urine.
- Heavy nosebleeds.
- Bleeding gums and easy bruising.
- Fever and infections.
- Low red blood cell count.
- Tiring easily.
Does anyone survive AML?
The 5-year survival rate for people 20 and older with AML is approximately 24%. For people younger than 20, the survival rate is 67%. Although AML is a serious disease, it is treatable and often curable with chemotherapy with or without a bone marrow/stem cell transplant (see the Types of Treatment section).
What is the treatment for APL?
The most important drugs for treating APL are non-chemo drugs called differentiating agents, like all-trans-retinoic acid (ATRA). Other treatments might include chemotherapy (chemo) and transfusions of platelets or other blood products. Treatment is typically divided into 3 phases: Induction (remission induction)
What is the most aggressive form of leukemia?
Acute promyelocytic leukemia (APL) is an aggressive type of acute myeloid leukemia. Learn more about APL and how it’s diagnosed. Chronic lymphocytic leukemia (CLL) is the most common chronic leukemia in adults.
How long can you live with APL leukemia?
Overall survival The 3-year survival rate improved from 54.6% in 1992-1995 to 66.0% in 1996-2001 and to 70.1% in 2002-2007. Survival decreased sharply in the first 2 months after the APL diagnosis (Figure 1). After 2 months, survival declined at a much lower rate for each time period of diagnosis.
Is AML hereditary?
Heredity or Genetic Factors Familial AML is a rare type of inherited leukemia which is transmitted by a non-sex chromosome in a dominant fashion. Certain genetic conditions can increase the risk for AML. Fanconi’s anemia is a congenital or inherited bone marrow disorder which often progresses to AML.
Which type of leukemia is most curable?
Acute Promyelocytic Leukemia (APL) Overview. While it is similar in many ways to the other subtypes, APL is distinctive and has a very specific treatment regime. Treatment outcomes for APL are very good, and it is considered the most curable type of leukemia.
What is APL in medical term?
Acute promyelocytic leukemia: Commonly called APL, a malignancy of the bone marrow in which there is a deficiency of mature blood cells in the myeloid line of cells and an excess of immature cells called promyelocytes. The peak incidence of APL is in young adults.
How is APL diagnosed?
Initial tests to diagnose APL Full blood count. A full blood count (FBC) measures the number of each type of cell in the blood: red cells, white cells and platelets. Bone marrow aspirate (biopsy) Cytogenetics/FISH tests. PCR test. Immunophenotyping. Blood clotting system tests. General health tests.
Can you die from APL leukemia?
In some countries, approximately one-third of patients with APL die within a month of beginning treatment. The deaths are due largely to a host of complications that are common with this cancer and its treatment.
What is the life expectancy with leukemia?
Latest figures show that the 5-year survival rate for all subtypes of leukemia is 61.4 percent. A 5-year survival rate looks at how many people are still alive 5 years after their diagnosis. Leukemia is most common in people aged over 55, with the median age of diagnosis being 66.
How rare is APL leukemia?
APL is of rare disease and comprises approx. 5% of all patients with newly diagnosed acute myeloid leukemia (AML).
How do you die with AML?
Death in patients with AML may result from uncontrolled infection or hemorrhage. This may happen even after use of appropriate blood product and antibiotic support.
How does arsenic work in APL?
Studies have shown that arsenic trioxide exerts dose-dependent dual effects on APL cells—it induces apoptosis (programmed cell death) preferentially at relatively high concentrations (0.5 × 10−6 to 2 × 10−6 M) and induces partial differentiation at low concentrations (0.1 × 10−6 to 0.5 × 10−6 M).
Does ATRA cause hair loss?
The standard of treatment for newly diagnosed patients with acute promyelocytic leukemia (APL) is all-trans retinoic acid (ATRA) plus anthracycline-based cytotoxic chemotherapy, a combination that is highly effective for remission induction. It does not cause hair loss and is not myelosuppressive in patients with APL.
