Last updated: June 24, 2021.https://www.uptodate.com/contents/differentiation-syndrome-associated-with-treatment-of-acute-leukemiaAccessed Nov 25, 2022. Acute Promyelocytic Leukemia (APL) is characterized by a block in differentiation where leukemic cells are halted at the promyelocyte stage. A characteristic balanced chromosomal translocation between chromosomes 15 and 17 t (15;17) (q24; q21) is seen in 95% of cases the translocation results in the formation of the PML-RARA fusion protein. Annexin II is also present on the surface of APL cells and facilitates the activation of plasmin, a molecule that breaks down blood clots. In the United States, the most prescribed consolidation regimen includes 4 monthly cycles of daily ATO together with daily ATRA. About 600 to 800 people develop acute promyelocytic leukemia (APL) in the United States each year. Treating Acute Myeloid Leukemia (AML) - American Cancer Society The stem cells can be obtained from the blood or bone marrow from a healthy donor (allogeneic transplantation) or from the patients own body (autologous transplantation) before the preparative regimen is initiated if a molecular remission was achieved. Other sites of bleeding include blood in the stools (hematochezia) due to gastrointestinal bleeding, blood in the urine (hematuria) due to bleeding in the genitourinary tract, excessive menstrual blood losses (menorrhagia) and excessive or recurrent nose bleeding (epistaxis). Reference: Data from the Newborn Screening Codingand Terminology Guide is available here. Introduction. It most often occurs within 2 to 21 days after treatment initiation and is characterized by fever, rash, swelling due to accumulation of fluid (edema), shortness of breath (dyspnea), low blood pressure (hypotension), kidney and liver dysfunction and accumulation of fluid within or around the lungs (pleural effusion) and the heart (pericardial effusion). 1 . This first-of-its-kind assistance program is designed for caregivers of a child or adult diagnosed with a rare disorder. Healthy volunteers may also participate to help others and to contribute to moving science forward. The PML-RAR [16] It produces less cardiotoxicity than anthracycline-based treatments and hence may be preferable in these patients. Research now indicates that patients who have previously achieved complete molecular remission with ATRA and ATO do not require maintenance therapy. Thrombotic events in acute promyelocytic leukemia. Acute promyelocytic leukemia: from highly fatal to highly curable. Acute promyelocytic leukemia (APL): remaining challenges towards a cure The PML-RARA gene fusion accounts for up to 98 percent of cases of acute promyelocytic leukemia. This type of genetic change, called a somatic mutation, is not inherited. Acute promyelocytic leukemia facts. Learn how CLL is diagnosed and staged and the, Acute lymphocytic leukemia is the most common childhood cancer, although it can develop in adults, too.

Patient organizations are available to help find a specialist, or advocacy and support for this specific disease. Our highly-specialized educational programs shape leaders to be at the forefront of cancer care and research. Appelbaum FR. A buildup of promyelocytes leads to a shortage of other kinds of blood cells, including red cells, white cells, and platelets. Acute promyelocytic leukemia (APL) is a biologically and clinically distinct variant of AML.

Mitrovic M, Suvajdzic N, Elezovic I, et al. It does so by enhancing interaction of nuclear co-repressor (NCOR) molecule and histone deacetylase (HDAC). Abaza Y, Kantarjian H, Garcia-Manero G, et al. APL was classified as AML-M3 in the older French-American-British (FAB) classification system and is currently classified as acute promyelocytic leukemia with t(15;17)(q24.1;q21.2);PML::RARA . In acquired aplastic anemia, an almost complete absence of hematopoietic stem cells results in low levels of red and white blood cells and platelets (pancytopenia). Studies have shown arsenic reorganizes nuclear bodies and degrades the mutant PML-RAR fusion protein. The following disorders are among those that most commonly present with symptoms resembling those of APL. 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). For some patients, especially those at higher risk of the APL coming back, consolidation may be followed by maintenance therapy, which uses lower doses of drugs over a longer period of time. What Is Acute Promyelocytic Leukemia (APL) - Verywell Health See additional information. J Oncol Pract 2018 Nov; 14(11): 649-657. doi: 10.1200/JOP.18.00328. Examples of infections that can present in a similar way to APL include infectious mononucleosis, HIV/AIDS, tuberculosis and bone infection (osteomyelitis). See our, URL of this page: https://medlineplus.gov/genetics/condition/acute-promyelocytic-leukemia/. Acute promyelocytic leukemia (APL) is a subtype of acute myeloid leukemia (AML), classified by a translocation between chromosomes 15 and 17 [t(15;17)], that is considered a true oncologic . Pulmonary hemorrhage can lead to cough, shortness of breath (dyspnea) and coughing up blood (hemoptysis). Whats the outlook for people who get APL? Park JH, Qiao B, Panageas KS, et al. If your doctor suspects that you have APL, theyll likely perform a complete blood count test to check the levels of your blood cells. 10th ed. A rearrangement of genetic material (translocation) between chromosomes 15 and 17, written as t(15;17), fuses part of the PML gene with part of the RARA gene. The main treatment for most types of AML is chemotherapy, sometimes along with a targeted therapy drug. Can Acute Myeloid Leukemia (AML) Be Prevented? Circulating blood cells are formed in a region in the middle of large bones known as the bone marrow and are all derived from a primitive type of cell known as the hematopoietic stem cell. NORD strives to open new assistance programs as funding allows. The most dangerous symptom of APL is the bleeding disorder (coagulopathy) associated with the disease. In normal cells, the RARA protein is bound to proteins and forms a complex that prevents genes involved in cellular differentiation from being read; this is called transcriptional repression. This leads to numerous complications, including bleeding and the formation of blood clots (thrombosis). Furthermore, the leukemic cells can spread to the bones and joints, which may cause pain in those areas. However, corticosteroids are sometimes given in advance with induction regimens in a preventive manner (prophylactically) to decrease the risk of differentiation syndrome. Can Acute Myeloid Leukemia (AML) Be Found Early? [3], Eight other rare gene rearrangements have been described in APL fusing RARA to promyelocytic leukemia zinc finger (PLZF),[10] nucleophosmin, nuclear matrix associated, signal transducer and activator of transcription 5b (STAT5B), protein kinase A regulatory subunit 1 (PRKAR1A), factor interacting with PAPOLA and CPSF1 (FIP1L1), BCL-6 corepressor or oligonucleotide/oligosaccharide-binding fold containing 2A (NABP1) genes. A buildup of promyelocytes leads to a shortage of other kinds of blood cells, including red cells, white cells, and platelets. Kayser S, Schlenk RF, Platzbecker U. Intravenous formulations of retinoid medications and oral forms of arsenic trioxide are currently in experimental clinical trials. These gene mutations lead to the overproduction of immature promyelocytes. [3] The RAR receptor is dependent on retinoic acid for regulation of transcription. Learn about the acute lymphocytic leukemia, Acute lymphoblastic leukemia is the most common type of childhood cancer. In addition to excessive bleeding, APL-associated coagulopathy increases the likelihood of forming abnormal blood clots that can dislodge and obstruct blood vessels (thromboembolism). Leung LKL, Evaluation and management of disseminated intravascular coagulation in adults, UpToDate. This test involves taking a small amount of the spongy marrow inside of your bones to study. Before the development of modern medical treatments, APL had one of the poorest prognoses of all acute leukemias, and people usually died within a month. 2020;4(8):1683-1689. doi:10.1182/bloodadvances.2019001278. Abeloffs Clinical Oncology. What is acute promyelocytic leukaemia (APL)? - Blood Cancer UK The hallmark of APL is genetic alterations involving the retinoic acid receptor alpha (RARA) gene. Key Statistics for Acute Myeloid Leukemia (AML). Ann Oncol 2016;27:1474-81. APL is caused by the uncontrolled proliferation of promyelocytes, a type of immature cell from the myeloid lineage of blood cells. APL starts with a mutation in the DNA of blood-producing cells in your bone marrow. In the induction phase, oral ATRA is combined with different medications for as long as 60 days or until complete remission is achieved. Ades L, Guerci A, Raffoux E, et al. Cicconi L, Lo-Coco F. Current management of newly diagnosed acute promyelocytic leukemia. Ryan MM. [6] Today, prognoses have drastically improved; 10-year survival rates are estimated to be approximately 80-90% according to one study. Patients therefore must be chosen and followed carefully throughout the entire process. [32] Incidence is higher among individuals of Latin American or South European origin.

JAMA Oncol. Although their exact cause is unknown, a probable contributing factor is the release of molecules that modulate immunity and inflammation (cytokines). This is usually combined with one of these: ATRA plus ATO is often the preferred treatment in people at lower risk of the leukemia coming back, as it tends to have fewer side effects. Acute promyelocytic leukemia - Cancer Therapy Advisor Although APL can occur at any age, middle-aged adults are most commonly affected; the median age at diagnosis is around 40. After complete remission is achieved, patients move to the consolidation phase, which aims to prevent relapse. Sanz MA, Montesinos P. How we prevent and treat differentiation syndrome in patients with acute promyelocytic leukemia. Fever, chills, night sweats and weight loss, which are collectively known as constitutional or B symptoms, are also common in APL. People who have a high risk of the disease returning may be given chemotherapy drugs. Studies report a 2-year survival rate as high as 97 percent in patients receiving ATRA treatment. 55 Kenosia Avenue Differentiation syndrome is a potentially severe complication of APL treatment that occurs in up to a quarter of patients. The American Cancer Society is a qualified 501(c)(3) tax-exempt organization. [13], Arsenic trioxide (As2O3) is currently being evaluated for treatment of relapsed/refractory disease. Acute promyelocytic leukemia is not inherited but arises from a translocation in the body's cells that occurs after conception. UpToDate Blood. Many types of NHL exist, including diffuse large B cell lymphoma (DLBCL), Burkitt lymphoma, mantle cell lymphoma, and follicular lymphoma. Its a good idea to check with a healthcare professional if you notice any potential warning signs such as abnormal bleeding, bruising easier than usual, or unexplained fatigue. The cells taken from a blood sample can also be evaluated by a physician specialized in disorders related to the blood (hematologist) to see if they are abnormal and potentially leukemic. [33] It can also occur as a secondary malignancy in those that receive treatment with topoisomerase II inhibitors (such as the anthracyclines and etoposide) due to the carcinogenic effects of these agents, with patients with breast cancer representing the majority of such patients.

In APL and other types of leukemia, the bone marrow is filled by malignant cells and is unable to produce functional cells. Bone marrow samples are obtained by bone marrow aspiration and biopsy, which are respectively used to collect the liquid and solid portions of the bone marrow. The number and severity of symptoms experienced may differ among people with this disease. promyelocytic leukemia. [3], APL is unique among leukemias due to its sensitivity to all-trans retinoic acid (ATRA; tretinoin), the acid form of vitamin A. American Cancer Society medical information is copyrightedmaterial. ), Acquired aplastic anemia is a rare blood disorder caused by failure of the bone marrow to produce blood cells. 10.1016/S0049-3848(10)70013-X. People with acquired agranulocytosis are susceptible to a variety of bacterial infections. International Consensus Classification of Myeloid Neoplasms and Acute Leukemias: integrating morphologic, clinical, and genomic data. Fax: 203-263-9938, Washington, DC Office Individuals may also experience excessive tiredness, pain in affected areas, loss of appetite, and weight loss. APL is treated differently than other forms of AML. Downs SM, van Dyck PC, Rinaldo P, et al. Patients with acute promyelocytic leukemia (APL), which is associated with disseminated intravascular coagulation-type symptoms, can present with mucosal bleeding, including gum bleeds, nosebleeds, or menorrhagia. 29;20(49):7186-203. doi: 10.1038/sj.onc.1204766. Consult doctors, other trusted medical professionals, and patient organizations. Blood. The characteristic symptom of APL is the associated bleeding disorder (coagulopathy), which can lead to excessive bleeding but also to blood clot formation (thrombosis). They can include: The development of APL is a medical emergency, and prompt treatment is needed. Commonly used blood products for the management of coagulopathies include platelets, fresh frozen plasma, and cryoprecipitate (a derivative of plasma proteins). In: DeVita VT, Lawrence TS, Rosenberg SA, eds. Karyotyping is a method where chromosomes are stained and visualized under a microscope during cell division. Acute promyelocytic leukemia (APL) is a is a unique subtype of acute leukemia characterized by abnormal proliferation of promyelocytes, life-threatening coagulopathy, and the chromosome translocation t(15;17)(q22;q11-12). Description Acute promyelocytic leukemia is a form of acute myeloid leukemia, a cancer of the blood-forming tissue ( bone marrow ). Am J Hematol 2012;87:596-603. Polymerase chain reaction (PCR) is a DNA sequencing technique that allows the detection of mutations and smaller insertions and deletions. Some patients may also have to undergo maintenance therapy, which usually consists of ATRA or ATRA and chemotherapy. Many patients are asymptomatic at the time of . Acute promyelocytic leukemia is a relatively rare and comprises about 7% to 8% of adult AML cases. It happens when there are too many of the blood-forming cells called promyelocytes in the blood and bone marrow. Phone: 202-588-5700. Blood 2019; 134(7):597-605. Powell BL, Moser B, Stock W, et al.
