  Acute Promyelocytic Leukemia (APL)   (Site not responding. Last check: 2007-11-05)
Acute promyelocytic leukemia (APL) is a subtype of the cancer acute myeloid leukemia (AML).
APL is characterized by abnormal, heavily granulated promyelocytes, a form of white blood cells.
APL is found more often in children between the ages of two and three, and in adults over 40, however it has also been found in older children and teenagers.

 Acute promyelocytic leukemia - Cancer information on MedicineNet.com
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.
APL is due to a translocation (an exchange of chromosome material) between chromosomes 15 and 17 which is symbolized t(15;17).
APL is considered a type of AML and is classified as the M3 variant of AML in the internationally accepted French-American-British (FAB) Classification.

 Acute Myeloid Leukemia (Adult) - Symptoms, Treatment and Prevention
There are two major types of leukemia : lymphocytic leukemia, which involves lymphoid-committed cells that form and mature in the lymphatic system, and myelogenous leukemia, which affects myeloid-committed cells that form and mature in the bone marrow.
Acute myelogenous leukemia (AML) is chiefly an adult disease with a median age at presentation of 50.
Leukemia is treated mainly with chemotherapy, although radiotherapy and biological therapy can play a part with some forms of the disease.

 Acute promyelocytic leukemia   (Site not responding. Last check: 2007-11-05)
Acute Promyelocytic Leukemia (APL) is a sub-type of Acute Non Lymphoblastic Leukemia (ANLL) classified as variant M3 under the French-American-British (FAB) classification.
Promyelocytic blast cells are characterized by a specific reciprocal translocation between chromosomes 15 and 17 t(15;17), which results in the fusion of a truncated retinoic acid receptor-alpha (RAR-alpha) gene to a transcription unit called PML (for promyelocytic leukemia).
APL can be cured in more than 90% of patients with trans-retinoic acid (ATRA) that has been demonstrated to induce maturation of leukemic cells.

 Childhood Acute Myeloid Leukemia/Other Myeloid Malignancies
The myeloid leukemias in childhood represent a spectrum of hematopoietic malignancies.
Leukemias with the chromosomal abnormalities t(8;21) and inv(16) are called core-binding factor leukemias; core-binding factor (a transcription factor involved in hematopoietic stem cell differentiation) is disrupted by each of these abnormalities.
Leukemia is always disseminated in the hematopoietic system at diagnosis, even in children with acute myeloid leukemia (AML) who present with isolated chloromas (also called granulocytic sarcomas).

Acute promyelocytic leukemia (APL), also known as M3, is the most common subtype of AML associated with DIC.
APL differs from other subtypes of AML in that patients are, on average, younger (median age 40 y) and most often present with pancytopenia rather than with elevated WBC counts.
APL is the subtype of AML that is most commonly associated with coagulopathy due to DIC and fibrinolysis.

 All-trans-retinoic acid in acute promyelocytic leukemia   (Site not responding. Last check: 2007-11-05)
Three hundred forty-six patients with previously untreated acute promyelocytic leukemia were randomly assigned to receive all-trans-retinoic acid or daunorubicin plus cytarabine as induction treatment.
By intention-to-treat analysis, the rates of overall survival at one, two, and three years after entry into the study were 75, 57, and 50 percent, respectively, among patients assigned to chemotherapy, and 82, 72, and 67 percent among those assigned to all-trans-retinoic acid (P= 0.003).
All-trans-retinoic acid as induction or maintenance treatment improves disease-free and overall survival as compared with chemotherapy alone and should be included in the treatment of acute promyelocytic leukemia.

Because of this liposomal formulation, they were able to receive greater cumulative doses and the duration of therapy was longer than is historically seen with the oral formulation alone.
Due to its effectiveness in inducing complete remissions in APL patients and its favorable safety profile, we believe Atragen could be a reliable and standardized dose of ATRA therapy for APL patients unable to reliably take the oral formulation," added Dr. Williams.
In addition to investigating the efficacy of Atragen in APL, the Company is conducting clinical trials to evaluate the potential of the product as a treatment for non-Hodgkin's lymphoma (Phase II), hormone-resistant prostate cancer (Phase II), acute myelogenous leukemia (Phase II) and renal cell carcinoma in combination with interferon alpha (Phase I/II).

Acute myelogenous leukemia is a cancer of blood-forming tissues of the bone marrow.
Patients with AML are susceptible to bleeding and infection as the normal blood cells lose their ability to fight microorganisms and decrease in number.
However, radiation, some toxins such as benzene, and some chemotherapy drugs (including etoposide and drugs known as alkylating agents) are thought to cause some kinds of leukemia, including AML.

 CancerWise - November 2004 - New Version of Leukemia Drug Better
As many as one-third of patients with a rare form of acute myelogenous leukemia (AML) have the possibility of a long-term, disease-free future without traditional chemotherapy using Lipo-ATRA, a new form of the drug ATRA, according to a recent study.
In the small Phase II trial, patients with acute promyelocytic leukemia (APL) were found to be disease-free for more than five years using Lipo-ATRA, says the study’s principal investigator Elihu Estey, M.D., professor in the M. Anderson Department of Leukemia.
The tendency for remissions induced by ATRA to be brief was originally thought to reflect the fact that little of the drug remains in the body over long periods of time.

Abstract: PML is a RING finger protein that normally resides within a specific subnuclear compartment termed the nuclear body.
In acute promyelocytic leukemia, the PML gene is fused to the retinoic acid receptor alpha (RARalpha) gene, resulting in the production of PML-RARalpha fusion proteins.
These studies should provide novel insights into the mechanism and function of sentrinization and increase our understanding of the pathogenesis of acute promyelocytic leukemia.
