๏‚žGroup of malignant disorders affecting
the blood and blood forming tissues of
the bone marrow, lymph system and
spleen
OR
๏‚žLeukemia is a cancer of blood forming
cells in the bone marrow.
The exact cause is still unknown
The risk factors include,
๏‚ž Genetic and environmental factors
๏‚ž Chromosomal changes( down syndrome)
๏‚ž Chemical agents, chemotherapeutic
agents
๏‚ž Viruses
๏‚ž Radiation and chemotherapy
๏‚ž Immunologic deficiencies
๏‚ž near nuclear bomb sites
๏‚ž Family history of leukemia
๏‚žAcute Vs chronic
๏‚žBased on the type of WBC involved
Acute leukemia
๏‚žCharacterized by proliferation of
immature hematopoietic cells.
๏‚žThe bone marrow will not produce
healthy blood cells.
๏‚žImmediate treatment is required to
avoid rapid progression
Chronic leukemia
๏‚ž Involve more mature forms of WBC and
the disease onset is more gradual
๏‚ž The cells are produced at a higher rate than
the normal, resulting in many abnormal
white cells in the blood.
๏‚ž Mostly occurs among old people
๏‚žAcute myelogenous leukemia(AML)
๏‚žAcute lymphocytic leukemia(ALL)
๏‚žChronic myelogenous leukemia(CML)
๏‚žChronic lymphocytic leukemia(CLL)
๏‚ž Represents only one fourth of all leukemias
๏‚ž Onset is abrupt
๏‚ž Increase in incidence with advancing age,
peak incidence between 60 and 70 years of
age
๏‚ž Characterized by uncontrolled proliferation of
myeloblasts( precursor of basophils and
esnophils)
๏‚ž Clinical manifestations

๏ถBone marrow aspiration
marked increase in myeloblasts
๏‚žMost common type of leukemia in
children
๏‚žPeak incidence between 2 and 9
years of age an in older adults
๏‚žImmature lymphocytes proliferate in
the bone marrow

๏ถLow, normal or high WBC count
๏ถHypercellular bone marrow with
lymphoblasts (an abnormal cell
resembling a large lymphocyte)
๏ถ Lymphoblasts present in the CSF
๏ถ Presence of philadelphia chromosome
(The Philadelphia
chromosome or Philadelphia translocation is a
specific genetic abnormality in chromosome 22
in case of leukemia cancer cells)
๏‚ž Accounts for 15% to 20% of all cases of
leukemia
๏‚ž Associated with benzene exposure and
high doses of radiation
๏‚ž Seen between 20 and 60 years of age
๏‚ž Caused by excessive development of mature
neoplastic granulocytes(a white blood cell with
secretory granules in its cytoplasm, e.g. an
eosinophil or a basophil) in the bone marrow
๏‚ž Excessive neoplastic granulocytes in the
peripheral blood infiltrate liver and spleen
๏‚žCells contains philadelphia
chromosome(serves as the disease
marker)
๏‚žResults from the translocation of
genetic material between
chromosomes 9 and 22
๏‚žIt has a chronic stable phase,
followed by the development of a
more acute, aggressive phase
referred to a the blastic phase
๏‚ž Clinical manifestations
๏ถ No symptoms early in the disease
๏ถ Fatigue and weakness
๏ถ Fever
๏ถ Sternal tenderness
๏ถ Weight loss
๏ถ Joint pain
๏ถ Bone pain
๏ถ Massive splenomegaly
๏‚ž Diagnostic findings
๏ƒ˜ Low RBC count
๏ƒ˜ Low Hb, Hct
๏ƒ˜ Normal no of lymphocytes, normal or low
no of monocytes
๏ƒ˜ Presence of philadelphia chromosome
๏‚žCommon leukemia in adults
๏‚žSeen between 50 to 70 years of age
๏‚žCharacterized by the production and
accumulation of functionally
inactive but long lived small mature
appearing lymphocytes
๏‚ž Lymphocytes infiltrate bone marrow,
spleen and liver
๏‚ž Lymph node enlargement present
๏‚ž Increased incidence of infection (T cell
deficiency)
๏‚žClinical manifestations
๏ƒผChronic fatigue
๏ƒผAnorexia
๏ƒผSplenomegaly and
lymphadenopathy
๏ƒผHepatomegaly
๏ƒผFever
๏ƒผWeight loss
๏ƒผFrequent infections
๏‚žDiagnostic findings
๏ƒ˜Mild anemia and thrombocytopenia
with disease progression
๏ƒ˜Total WBC count > 100,000|micro
litre
๏ƒ˜Increase in peripheral lymphocytes
๏ƒ˜Increase in the presence of
lymphocytes in bone marrow
๏‚žChemotherapy
๏ƒผFirst stage : Induction therapy (
attempt to induce or bring about a
remission)
๏ƒผSecond stage: post induction or post
remission chemotherapy
* intensification
* consolidation
* maintenance therapy
๏‚ž Seeks to destroy leukemic cells in the
tissues, peripheral blood and bone
marrow in order to restore normal
hematopoiesis
๏‚ž Chemotherapeutic agents cytarabine
and anti tumour antibiotics(
daunorubicin, doxorubicin, idaribicin)
๏‚žIntensification therapy
๏ƒ˜Given immediately after induction
therapy for several months
๏ƒ˜Includes the same drugs as those
used in induction but at higher
dosages
๏‚ž Consolidation therapy
๏ƒผ Started after a remission is achieved
๏ƒผ Consists of one or two additional courses
of the same drugs given during induction
or involve high dose therapy
๏ƒผ Purpose eliminate remaining
leukemic cells that may or may not be
clinically evident
๏‚žMaintenance therapy
๏ƒผTreatment with lower doses of the
same drugs used in induction or
other drugs given every 3 to 4 weeks
for a prolonged period of time
๏‚ž In addition to chemotherapy,
corticosteroids and radiation therapy are
used

patient for bone marrow transplantation
๏‚ž In ALL prophylactic intrathecal
methotrexate or cytarabine ( given to
decrease the chance of CNS involvement)

methotrexate, fludarabine

๏‚ž Mitotic inhibitors: vincristine, vinblastine
๏‚ž BIOLOGICAL THERAPY
it is used to help the immune
system to recognize and attack leukemia cells.
Eg: Rituximab, Gemtuzumab ozogamicin
๏‚ž TARGETTED THERAPY:
In targetted therapy uses drugs
that attacks the specific vulnerabilities with in
cancer cells.
Eg: imatinib
๏‚ž RADIATION THERAPY
radiation therapy uses X-Rays or other
high energy beams to damage the leukemia
cells and to stop their growth.
๏‚ž STEM CELL TRANSPLANTATION
it is a procedure to replace diseased
bone marrow with healthy bone marrow.
๏‚ž Assess the general condition of the patient
๏‚ž Closely monitor the lab values
๏‚ž Maintain good IPR with the patient
๏‚ž Provide psychological support
๏‚ž Instruct the patient to have a well balanced
diet
๏‚ž Monitor vital signs
๏‚ž Include family members also in providing
care
๏‚ž Explain the side effects of chemotherapy and
radiation therapy
๏‚ž Administer antibiotics
๏‚ž Maintain aseptic techniques while doing the
procedures
๏‚ž Proper isolation of the patient
๏‚ž Provide health education to the patient
๏‚ž Imbalanced nutrition less than body requirement
related to inadequate nutritional intake and
anorexia
๏‚ž Activity intolerance related to weakness and
imbalance between oxygen supply and demand
๏‚ž Impaired oral mucous membrane related to low
platelet count
๏‚ž Ineffective therapeutic regimen management
related to lack of knowledge of disease
process, activity and medication
๏‚ž Risk for infection related to bone marrow
depression
