Acute promyelocytic leukemia is sometimes found related with disseminated intravascular.  Apl is a sub type of acute myeloid leukemia (aml), which is classified into seven major sub types, m1 to m7, depending on the type of myeloid cell which is abnormal. Of these seven subtypes, the patients with m3 or acute promyelocytic leukemia are found to have higher life expectancy of survival and better outcomes.

A special form of  differentiation therapy, called all-trans-retinoic-acid (atra) therapy, is employed for the treatment for acute promyelocytic leukemia. Acute promyelocytic leukemia is a type of cancer, in the leukemia category of cancer disease processes. This condition is considered a sub-classification or sub-type of acute myelogenous leukemia,. Acute promyelocytic leukemia is defined by a characteristic morphology (aml fab m3/m3v), by the specific translocation t(15;17) and its molecular correlates (pml/rara and rara/pml). With arsenic trioxide (ato) monotherapy remission rates over 80% were achieved and long-lasting molecular remissions are described.

Acute promyelocytic leukemia is a very smart treatment option for developing countries mainly because of the low cost involved along with the favorable toxicity profile. Acute promyelocytic leukemia is well-known from other leukemia subtypes by a test for the rar? This form of acute myelogenous leukemia was first identified as subtype of leukemia in 1957.

Acute promyelocytic leukemia is the result of a translocation of chromosomes 15 and 17. Acute promyelocytic leukemia is related in some patients with the development of a potentially lethal syndrome that is not uniformly accompanied by peripheral blood leukocytosis.

This means that acute promyelocytic leukemia or a subtype of acute promyelocytic leukemia, affects less than 200,000 people in the us population. Acute promyelocytic leukemia is frequently associated with bleeding caused by disseminated intravascular coagulation (dic). Acute promyelocytic leukemia is characterized by chromosomal translocation involving the retinoic acid receptor-alpha gene on chromosome 17. Gene on chromosome 17 is involved in a reciprocal translocation with the promyelocytic leukemia gene .

Acute promyelocytic leukemia is superior to two-drug combination induction therapy in terms of the molecular response. Acute promyelocytic leukemia is very destructive, being a fast growing, deathly and serious form of leukemia.

In the peripheral blood the specialists can observe the existence of low white cell count (leucopenia) and a high white cell count (leukocytosis). Some doctors believe that the bleeding may be a cause of dic (disseminated intravascular coagulation) with which they often associate acute promyelocytic leukemia.

Acute promyelocytic leukemia is associated with leukocytosis, variant morphology and poorer prognosis.
