This chapter covers acute myeloid leukaemia (AML) and acute lymphoblastic leukaemia (ALL), and includes information on prognostic factors, current standard of care, basic biology, epidemiology, clinical presentation, diagnosis, pathophysiology, aetiology, and management.
Although the majority of patients with acute myeloid leukaemia (AML) achieve complete remission with induction chemotherapy. Acute myeloid leukemia (AML) was initially subdivided according to morphology (the French-American-British system), which proved helpful in pathologic categorization.
Subsequently, clinical and genomic factors were found to correlate with response to chemotherapy and with overall survival. These included a history of antecedent hematologic disease, a history of chemotherapy or Cited by: 6 - Acute Lymphoid Leukaemias (ALL) and Minimal Residual Disease in ALL.

Acute leukaemia is a malignant clonal expansion of a haemopoietic stem cell. Abnormal white cells accumulate in the bone marrow, gradually replacing normal haemopoietic cells. The result is bone marrow failure and the spilling over of abnormal cells into the peripheral blood.

The most obvious pathologic feature in the acute leukemias is the accumulation of undifferentiated blasts in the marrow and other tissues, indicating that, unlike the myeloproliferative disorders, acute leukemias have defects that block or significantly retard.
Acute myeloid leukemia (AML) is a cancer of the myeloid line of blood cells, characterized by the rapid growth of abnormal cells that build up in the bone marrow and blood and interfere with normal blood cell production.
Symptoms may include feeling tired, shortness of breath, easy bruising and bleeding, and increased risk of infection. Occasionally, spread may occur to the brain, skin, or gums. Acute lymphocytic leukemia (ALL) is also called acute lymphoblastic leukemia.
“Acute” means that the leukemia can progress quickly, and if not treated, would probably be fatal within a few months. "Lymphocytic" means it develops from early (immature) forms of lymphocytes, a. Acute myeloid leukemia (AML) results from accumulation of abnormal myeloblasts, most commonly in the bone marrow, leading to bone marrow failure and death.
Peripheral blood involvement is frequent, while infiltration of organs, most ominously the brain and/or lung is rare and seen most often in patients with high blood blast counts (eg, >50 Of all the translocations, t (15;17) is generally found in acute promyelocytic leukemia.
On the other hand, t (8;21) is a characteristic feature of acute myeloblastic leukemia with maturation . Translocation between chromosome 8 and 14 is found in B-cell acute lymphoblastic leu-kemia .
This text presents insights into the future of the diagnosis of acute leukaemias and other haematologic disorders, as instrumentation becomes more complex. The book expands on basic and practical knowledge of acute leukaemias beyond the FAB classification. Acute promyelocytic leukaemia (APL) is a distinctive sub-type of acute myeloid leukaemia that has distinct biologic and clinical features.
According to the older French-American-British (FAB) classification of AML, based solely on morphology as determined by the degree of differentiation along different cell lines and the extent of cell maturation (Cheson et al ), APL is sub-typed as AML-M3.
Book • Browse book content This chapter presents nine cases of various acute leukaemias. Final diagnosis includes acute myeloid leukaemia, acute promyelocytic leukaemia, acute myelomonocytic leukaemia, acute monoblastic leukaemia, acute erythroid leukaemia, acute megakaryocytic leukaemia, and acute lymphoblastic leukaemia.
Frederick R. Appelbaum, in Abeloff's Clinical Oncology (Sixth Edition), Abstract. Acute leukemia is the result of a series of mutational events occurring in an early hematopoietic precursor that prevents the progeny of that precursor from maturing normally but allows them to proliferate in an uncontrolled fashion.
The result is the rapid expansion of an immature population of myeloid (in. Leukaemias are broadly divided into: (i) acute leukaemias, which, if untreated, lead to death in weeks or months; and (ii) chronic leukaemias, which, if untreated, lead to death in months or years.
They are further divided into lymphoid, myeloid and biphenotypic leukaemias, the latter showing both lymphoid and myeloid differentiation. Acute. Leukemia, also spelled leukaemia, is a group of blood cancers that usually begin in the bone marrow and result in high numbers of abnormal blood cells.
These blood cells are not fully developed and are called blasts or leukemia cells. Symptoms may include bleeding and bruising, feeling tired, fever, and an increased risk of infections. These symptoms occur due to a lack of normal blood cells.

Although most cases of MDS or acute leukemia are sporadic diseases, it is becoming clear that a subgroup of cases is associated with germ line mutations and is familial. 74 A major change to the revision of the WHO classification is the addition of a section on myeloid neoplasms with germ line predisposition, which includes cases of MDS.

acute leukemia, the white blood count may remain low because the cells are halted at the blast stage. Acute forms may occur in both adults and children. • Chronic forms: Onset is much slower, often over months or years. Normal cell production may occur as well for a long period of time, but in late stages of chronic disease, the abnormal cells.
AML-MO represents % of all cases of AML and % of all acute leukaemias. Its clinical and biological significance is not yet apparent but. Acute leukaemias (AL) correspond to 25–35% of all cancer cases in children. The aetiology is still sheltered, although several factors are implicated in causality of AL subtypes.
Childhood acute leukaemias are associated with genetic syndromes (5%) and ionising radiation as risk factors. Somatic genomic alterations occur during fetal life and. acute leukaemias and selection of monoclonal antibodies. Data sources: The literature review was obtained through internet, journals and chapters in the relevant books.
Data selection: Relevant articles and chapters on immunophenotyping of acute leukaemias were selected from respected international journals and books in the field. The main reasons for return to the primary acute care service were infection 33/93 (36%), mental status changes 16/93 (17%), cardiac 11/93 (12%), functional decline 9/93 (10%), completed rehabilitation but not safe medically to discharge 6/93 (7%), further leukemia treatment 5/93 (5%), and gastrointestinal 4/93 (4%).

Leukaemias may be divided into: acute leukaemias: show rapid proliferation of relatively undifferentiated malignant cells; are characterised by the development of bone marrow failure with consequent anaemia, neutropenia, and thrombocytopenia; are the most common leukaemias among children; chronic leukaemias: have a relatively prolonged natural.
Acute myeloid leukaemia (AML) – This is the most common type of acute leukaemia in adults, with about people diagnosed each year. It becomes more common with age and mostly occurs after Acute lymphoblastic leukaemia (ALL) – About people are diagnosed each year. Of these, more than are children under Flow cytometry is an integral tool in both the diagnosis and posttherapy evaluation of acute myeloid leukemia (AML).
The strength of the technology is its capacity for rapid, sequential single-cell analysis with simultaneous evaluation of multiple antigens, thus providing a comprehensive immunophenotype for discrete cellular subpopulations.

Immunophenotyping is an essential part of the modern diagnostic workup of acute leukemias and thus for an appropriate treatment of these complex and heterogeneous diseases. It provides a lot of useful information in this setting that transfers directly from laboratory to clinical management of patients.
Lineage definition is the first goal leading to proper initial therapy. In the acute group, AML was more common than ALL, and in the chronic group CML was commoner than CLL.
After subtyping of acute leukaemias with cytochemistry, the study showed in AML, 2 cases of M0 (8%), 6 cases of M1 (25%), 13 cases of M2 (55%), 1 case of M3 (4%), 2 cases of M4 (8%).
No cases of M5, M6 and M7 were detected.
