When was APL first used?
After the initial therapeutic success reported in 1973 using an anthracycline (daunorubicin),1the management and outcome of acute promyelocytic leukemia (APL) has been revolutionized by the introduction of all-transretinoic acid (ATRA; tretinoin) and arsenic trioxide (ATO) in 19882and 1996,3respectively. Multicenter studies over the past 3 decades have demonstrated the efficacy of ATRA plus chemotherapy and, subsequently, of ATRA plus ATO, with or without chemotherapy. However, the optimal management of APL also requires early diagnosis, institution of aggressive supportive measures, appropriate management of treatment-related complications, and monitoring of measurable residual disease (MRD).
Can APL be treated in hospital?
To prevent very early deaths occurring prior to treatment, individuals with suspected APL should be immediately hospitalized and managed as a medical emergency. The diagnosis must be confirmed at the genetic level by experienced reference laboratories. However, even before confirmation, ATRA and measures to counteract the coagulopathy should be initiated immediately based solely on the clinical suspicion of APL and review of the peripheral blood (PB) smear (Table 1).
Is APL hereditary?
No, a person cannot inherit APL. APL is the result of a somatic mutation. A somatic mutation is an abnormality that occurs in a person’s genes after conception and does not pass from parent to child.
1. Induction
The aim of the induction stage is to reduce the number of APL cells, ultimately leading to remission. Remission is when there are no or very low levels of cancerous cells.
2. Consolidation
Consolidation can help keep a person in remission from APL. It can also help remove any remaining APL cells. A person will generally receive the same drugs that they had during the induction phase. However, the dosage or timing of their treatment may change.
3. Maintenance
If a person has a higher risk of their APL returning, they may require further treatment after consolidation. Maintenance therapy involves a person receiving lower dosages of drugs over a longer period.
Differentiation syndrome
Both ATRA and ATO can cause differentiation syndrome. This side effect occurs when the leukemia cells release chemicals into the bloodstream, which can result in:
What is the treatment for acute myeloid leukemia?

How long do you stay on maintenance after cancer treatment?
After consolidation therapy, people with high-risk disease may stay on maintenance therapy for a few years to keep the cancer from coming back. This therapy is given intermittently and combines ATRA and low-dose chemotherapy.
What is the treatment for cancer that can't be detected?
This means that the cancer can no longer be detected, which is called remission. After the disease is in remission, they are then given consolidation therapy . This includes additional cycles of ATRA and arsenic trioxide.
Can you avoid chemotherapy with APL?
People with lower-risk forms of APL may be able to avoid chemotherapy altogether. Others may need chemotherapy as part of their consolidation therapy.
What type of cell is a promyelocyte?
A promyelocyte is a type of myeloid cell that normally matures to granulocytes. Eosinophils, neutrophils, and basophils are the three types of mature granulocytes. Leukemia is defined as the uncontrolled proliferation of abnormal leukocytes in the blood and bone marrow.
How to diagnose APL?
Once cells are obtained, they can be evaluated in numerous ways to confirm the diagnosis of APL and characterize the affected cells. Flow cytometry is a laboratory method where cells are suspended in fluid and processed into an instrument known as a flow cytometer. The cells flow one at a time through a laser, and the pattern of light scattering and cell fluorescence allows identification of cells based on their size, shape, and the presence or absence of specific markers on the cell surface (immunophenotyping). The genes and chromosomes of the affected cells can also be evaluated. Karyotyping is a method where chromosomes are stained and visualized under a microscope during cell division. Fluorescence in situ hybridization (FISH) is a technique where selected chromosomal regions are stained to identify large genetic insertions, deletions, or translocations. Polymerase chain reaction (PCR) is a DNA sequencing technique that allows the detection of mutations and smaller insertions and deletions. Next generation sequencing (NGS) is a method of evaluating multiple genes simultaneously for mutations.
What is the coagulopathy associated with APL?
The coagulopathy associated with APL is multifactorial. In addition to thrombocytopenia, which can lead to bleeding in many types of leukemia, other molecules present in promyelocytes contribute to the severity of the coagulopathy encountered in APL. Notably, tissue factor (TF), a molecule found on the surface of APL cells, activates the coagulation cascade. Annexin II is also present on the surface of APL cells and facilitates the activation of plasmin, a molecule that breaks down blood clots. Overall, the action of tissue factor and annexin II, in combination with other molecules, leads to excessive clotting (thrombosis), and excessive bleeding due to consumption of coagulation factors and excessive breakdown of clots.
What is the name of the type of white blood cell that increases with age?
Summary. Acute promyelocytic leukemia (APL) is a blood cancer characterized by a marked increase in a type of white blood cells known as promyelocytes, a type of immature white blood cell. It develops in about 600 to 800 individuals each year in the United States, most often in adults around the age of 40. The characteristic symptom of APL is the ...
What age is APL most common?
APL most commonly occurs in middle-aged individuals. The median age at diagnosis is around 40 years, meaning that half of cases occur in people under that age and the other half in people above that age. In APL, the bone marrow is overcrowded with malignant cells and eventually fails to produce normal blood cells required for normal functioning. Depletion of red blood cells (anemia) leads to symptoms such as fatigue and pallor, while a decreased number of functional white blood cells predispose affected individuals to infections. A decreased number of platelets (thrombocytopenia) increases the risk of bleeding and bruising.
What is the most dangerous symptom of APL?
A decreased number of platelets (thrombocytopenia) increases the risk of bleeding and bruising. The most dangerous symptom of APL is the bleeding disorder ( coagulopathy) associated with the disease. Coagulopathy is common in all types of leukemia, mainly due to thrombocytopenia.
How long does ATRA last?
In the induction phase, oral ATRA is combined with different medications for as long as 60 days or until complete remission is achieved. Depending on the treatment regimen used, ATRA can be combined with idarubicin, daunorubicin and cytarabine, or arsenic trioxide (ATO) with or without gemtuzumab ozogamicin (GO).
How long does it take for AML to come back?
Clinical trials of new treatment approaches might also be an option. If AML comes back sooner than 12 months, most doctors will advise a stem cell transplant for younger patients, if possible. Taking part in a clinical trial is another option.
What is the treatment for AML?
For AML with a mutation in the IDH1 or IDH2 gene. If the leukemia cells have an IDH1 or IDH2 gene mutation, one option if the leukemia doesn’t go away or if it comes back later might be treatment with a targeted drug called an IDH inhibitor, such as ivosidenib (Tibsovo) for AML with an IDH1 mutation, or enasidenib ...
What to do if AML doesn't go away?
If AML doesn’t go away completely with induction treatment, sometimes a second, similar course of chemotherapy (chemo), often called reinduction, can be tried. If this isn't helpful, treatment with other chemo drugs or more intensive doses of chemo may be tried, if the person can tolerate them. A stem cell transplant may be an option ...
What is supportive care for leukemia?
Supportive treatment for leukemia that won't go away. If further treatment or a clinical trial is not an option, the focus of treatment may shift to controlling symptoms caused by the leukemia, rather than trying to cure it. This is called palliative treatment or supportive care.
How to tell if you have leukemia?
Other common symptoms from leukemia are low blood counts and fatigue. Medicines or blood transfusions may be needed to help correct these problems. Nausea and loss of appetite can be treated with medicines and high-calorie food supplements. Infections that occur may be treated with antibiotics.

Does AML go away?
Most often, acute myeloid leukemia (AML) will go into remission after the initial treatment. But sometimes it doesn't go away completely, or it comes back (relapses) after a period of remission. If this happens, other treatments can be tried, as long as a person is healthy enough for them.
Why should APL be considered in every patient with newly diagnosed AML?
APL should be considered in every patient with newly diagnosed AML because the treatment is so urgent, effective, and different from that of all other subtypes of AML. Although the majority of patients with APL are cured of their disease with contemporary strategies, several important questions remain to be addressed in future studies to cure all patients. First, what is the best treatment for high-risk patients? Is administering intermediate- or high-dose Ara-C in consolidation or ATO preferable? Second, will the combination of ATRA and ATO with minimal or no chemotherapy replace standard therapy with ATRA plus anthracyclines? Ongoing cooperative group comparisons, such as the North American Intergroup trial S0535, evaluating concurrent ATRA, ATO, and GO for induction followed by 3 courses of consolidation with daunorubicin plus ATRA, ATO, and GO than maintenance and the GIMEMA [b]/DSIL-APL0406 protocol, which compares ATRA plus ATO with minimal chemotherapy to standard ATRA plus anthracycline, will be of great interest.
What is the best treatment for APL?
At this time, the best induction strategy appears to be simultaneous administration of ATRA plus cytotoxic chemotherapy . Concurrent ATRA and chemotherapy are commenced immediately as discussed earlier in “Begin ATRA before confirmation of the diagnosis” ( Table 1 ). For patients with high-risk disease or for those who develop a WBC count more than 10 000/μL during therapy, CNS prophylaxis can be considered once CR has been achieved with administration of 4 weekly courses (the number is arbitrary to some extent) of intrathecal methotrexate or alternating with cytosine arabinoside (Ara-C) in an effort to prevent relapse in the CNS, although there are no data to support this approach. 45, 46 New strategies for future studies in high-risk patients include prophylactic corticosteroids, low-molecular weight heparins, the addition of FMS-like tyrosine kinase-3 (FLT3) inhibitors given the high incidence of FLT3 internal tandem duplication gene mutations, and autologous hematopoietic stem cell transplantation (HSCT) in first CR because this is an effective strategy for patients in second molecular CR (CR2) and transplantation-related mortality is extremely low. 47-49
What is APL in medical terms?
Acute promyelocytic leukemia (APL) is a subtype of acute myeloid leukemia (AML) with distinctive biologic and clinical features that is now highly curable. Most patients are young, present with leukopenia, and exhibit a life-threatening coagulopathy, which is the most notorious manifestation of the disease. The cells from almost all patients have a balanced reciprocal translocation between chromosomes 15 and 17, 1 which generates a fusion transcript joining the PML (promyelocyte) and RAR -α (retinoic acid receptor-α) genes. 2 Leukemic promyelocytes have the unique ability to undergo differentiation with exposure to retinoic acid and both differentiation and apoptosis with exposure to arsenic trioxide (ATO). The disease is relatively rare in adults, accounting for only 10% to 15% of the approximately 13 400 adults diagnosed with AML in the United States each year. Although the incidence of APL among children with AML is similar in some series, a higher overall percentage of APL in children with AML compared with adults has been reported in others. 3 In children, the disease is often associated with a high white blood cell count (WBC > 10 000/μL), the microgranular variant (M3V), and more all- trans retinoic acid (ATRA)-related toxicities, particularly pseudotumor cerebri. 4
How to diagnose APL?
The presumptive diagnosis of APL can usually be made by review of the peripheral blood smear alone or with the bone marrow aspirate and core biopsy by an experienced hematologist and hematopathologist in the presence of the characteristic clinical findings. 9 The peripheral blood smear often shows leukopenia with circulating promyelocytes, which usually have abundant, often irregular-appearing primary azurophilic granules. Leukemic promyelocytes with multiple Auer rods may be found and are identified only in APL ( Figure 1 ). Although often obscured by the granules, the nuclear contour is bilobed or reniform in appearance. The latter feature is important because patients with the M3V have the same predisposition toward catastrophic bleeding yet the same excellent outcome with appropriate treatment 10 ( Figure 2 ). Abundant primary azurophilic granules, although strongly suggestive of APL, do not confirm the diagnosis because leukemic cells from some patients with other subtypes of AML may have such prominent granules ( Figure 3 ). Appreciation of these details of the morphology in APL by practicing hematologists is critical because this is the one subtype of AML for which immediate treatment must begin when the disease is first suspected and an experienced hematopathologist may not be immediately available.
What is the GIMEMA-AIEOPAIDA protocol?
GIMEMA-AIEOPAIDA protocol for the treatment of newly diagnosed acute promyelocytic leukemia (APL) in children.
Is promyelocytic leukemia curable?
Acute promyelocytic leukemia is the first malignant disease highly curable with targeted therapy directed at a unique molecular abnormality. The characteristic bleeding diathesis is the most notorious manifestation of the disease, which historically has accounted for a high mortality rate during induction. Acute promyelocytic leukemia is one of the few hematologic diseases that must be recognized under the microscope by the practicing hematologist because early institution of all- trans retinoic acid (ATRA) at the first suspicion of the disease before confirmation of the diagnosis and aggressive blood product support are critical to reduce early mortality. ATRA plus anthracycline-based chemotherapy for induction and consolidation followed by maintenance ATRA with low-dose chemotherapy is currently the standard of care. However, the combination of ATRA and arsenic trioxide, with minimal chemotherapy to control leukocytosis, is very effective therapy for newly diagnosed patients. This combination may replace conventional approaches for most, if not all, patients in the very near future. Acute promyelocytic leukemia should be considered in any patient with newly diagnosed acute myeloid leukemia because the treatment is urgent and different from all other subtypes.
Is acute leukemia fatal?
