==Overview==
The [[Natural history of disease|natural history]] of acute promyelocytic leukemia is characterized by [[Symptom|symptoms]] related to defective normal [[blood cell]] production. These [[Symptom|symptoms]] include [[fatigue]], [[bleeding]], and [[infection]]. [[Complication (medicine)|Complications]] include [[thrombosis]] and [[hemorrhage]], which eventually occur in a significant proportion of [[Patient|patients]]. Early death is common and is related to [[bleeding]] [[Complication (medicine)|complications]]. Therapy-related [[Complication (medicine)|complications]] include [[differentiation]] [[syndrome]], [[QT prolongation|QT interval prolongation]], and [[cardiomyopathy]]. The [[prognosis]] of acute promyelocytic leukemia was previously poor, but the advent of [[arsenic trioxide]] and all-''[[trans]]'' [[retinoic acid]] has rendered the [[prognosis]] to be far more favorable in the recent years.

==Natural History==
==Natural History==
* Acute promyelocytic leukemia typically begins with a combination of [[Symptom|symptoms]] including [[fatigue]], [[bleeding]], and [[Infection|infections]] (such as upper [[respiratory tract infection]]). [[Patient|Patients]] typically present to their [[primary care physician]] with such [[Symptom|symptoms]], and a [[complete blood count]] usually reveals a low [[white blood cell]] count, low [[hemoglobin]], and low [[platelet count]]. A [[bone marrow biopsy]] is usually done to work up the [[abnormal]] [[laboratory]] values, and a [[diagnosis]] of acute promyelocytic leukemia is made. In the first few days to weeks of the [[disease]], there is a high risk of [[bleeding]] due to [[disseminated intravascular coagulation]], a condition characterized by [[abnormal]] [[thrombus]] formation and breakdown.<ref name="pmid16504043">{{cite journal| author=Franchini M, Lippi G, Manzato F| title=Recent acquisitions in the pathophysiology, diagnosis and treatment of disseminated intravascular coagulation. | journal=Thromb J | year= 2006 | volume= 4 | issue=  | pages= 4 | pmid=16504043 | doi=10.1186/1477-9560-4-4 | pmc=1402263 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=16504043  }} </ref>

==Prognosis==
==Prognosis==
Prior to the introduction of readily available diagnostics and targeted therapeutics, the prognosis of acute promyelocytic leukemia was previously very poor, especially in the early phase of the disease. The poor prognosis was due to high bleeding risk and death from hemorrhagic complications due to [[disseminated intravascular coagulation]]. Death typically occurs with a few days to weeks in the absence of treatment. The early death rate is estimated to be 17.3%, based on a large population-based analysis conducted in the United Stated between 1992-2007.<ref name="pmid23556100">{{cite journal| author=Park J, Jurcic JG, Rosenblat T, Tallman MS| title=Emerging new approaches for the treatment of acute promyelocytic leukemia. | journal=Ther Adv Hematol | year= 2011 | volume= 2 | issue= 5 | pages= 335-52 | pmid=23556100 | doi=10.1177/2040620711410773 | pmc=3573416 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=23556100  }} </ref> <ref name="pmid29541170">{{cite journal| author=Chen C, Huang X, Wang K, Chen K, Gao D, Qian S| title=Early mortality in acute promyelocytic leukemia: Potential predictors. | journal=Oncol Lett | year= 2018 | volume= 15 | issue= 4 | pages= 4061-4069 | pmid=29541170 | doi=10.3892/ol.2018.7854 | pmc=5835847 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=29541170  }} </ref> The 5-year survival rate is only 30-40% after 5 years in younger patients.<ref name="pmid28352191">{{cite journal| author=McCulloch D, Brown C, Iland H| title=Retinoic acid and arsenic trioxide in the treatment of acute promyelocytic leukemia: current perspectives. | journal=Onco Targets Ther | year= 2017 | volume= 10 | issue=  | pages= 1585-1601 | pmid=28352191 | doi=10.2147/OTT.S100513 | pmc=5359123 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=28352191  }} </ref> In the current era of medicine (after the introduction of all-''trans'' retinoic acid and arsenic trioxide, the prognosis of acute promyelocytic leukemia carries a much better prognosis.<ref name="pmid25885425">{{cite journal| author=Coombs CC, Tavakkoli M, Tallman MS| title=Acute promyelocytic leukemia: where did we start, where are we now, and the future. | journal=Blood Cancer J | year= 2015 | volume= 5 | issue=  | pages= e304 | pmid=25885425 | doi=10.1038/bcj.2015.25 | pmc=4450325 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=25885425  }} </ref> Patients can achieve long-term, durable remission if treated appropriately in an expedited manner with medications such as [[all-''trans'' retinoic acid]], [[arsenic trioxide]], or cytotoxic chemotherapy.

Overview

The natural history of acute promyelocytic leukemia is characterized by symptoms related to defective normal blood cell production. These symptoms include fatigue, bleeding, and infection. Complications include thrombosis and hemorrhage, which eventually occur in a significant proportion of patients. Early death is common and is related to bleeding complications. Therapy-related complications include differentiation syndrome, QT interval prolongation, and cardiomyopathy. The prognosis of acute promyelocytic leukemia was previously poor, but the advent of arsenic trioxide and all-trans retinoic acid has rendered the prognosis to be far more favorable in the recent years.

Natural History

Complications

In a 2015 study from MD Anderson Cancer Center, it was shown that the annual incidence of venous thromboembolism, which includes deep vein thrombosis and pulmonary embolism, was 6.1-42%, which is the highest amongst all leukemia sub-types. In contrast, the incidence of venous thromboembolism in chronic myeloid leukemia was only 1.5%.[7]

Prognosis

  • Prior to the introduction of readily available diagnostics and targeted therapeutics, the prognosis of acute promyelocytic leukemia was previously very poor, especially in the early phase of the disease.[31][32]
  • The poor prognosis was due to high bleeding risk and death from hemorrhagic complications due to disseminated intravascular coagulation. Death typically occurs within a few days to weeks in the absence of treatment. The early death rate is estimated to be 17.3%, based on a large population-based analysis that was conducted in the United Stated between 1992-2007.[33] [2]
  • The 5-year survival rate is only 30-40% after 5 years in younger patients.[23] In the current era of medicine (after the introduction of all-trans retinoic acid and arsenic trioxide), the prognosis of acute promyelocytic leukemia carries a much better prognosis.[3]
  • Patients can achieve long-term, durable remission if treated appropriately in an expedited manner with medications such as all-''trans'' retinoic acid, arsenic trioxide, or cytotoxic chemotherapy. The current overall survival rate is 86-97%, and the complete remission rate is 90-100%.[23]
  • In a multi-center study published in 2017 that evaluated the long-term outcomes of patients with acute promyelocytic leukemia, the complete remission rate was 96% [34] and induction mortality if low at 4%.[34]
