Blast cell
• Blast cells are immature precursors of either
lymphocytes (lymphoblasts), or granulocytes
(myeloblasts).
• They do not normally appear in peripheral blood.
they can be recognized by their large size, and
primitive nuclei .
• Presence of blast cells in blood, signify
ACUTE LEUKEMIA.

Definition
• Leuka = white, emia = blood
• Leukemia is a type of cancer of blood or
bone marrow.
• Characterized by an abnormal increase of
immature white blood cells called "blasts".
• Leukemias are the most common cancers
affecting children.
2/13/2023
Leukemia in Children
 Acute lymphoblastic leukemia (ALL)
accounts for 73%,
 Acute myeloid leukemia (AML) accounts
for approximately 18%.
 Chronic myeloid leukemia (CML) is rarely
seen, accounting for less than 4%.
10
Epidemiology
–
–
Most common childhood cancer
– 3,000 new cases each year
Demographics:
• Males more commonly than females
• Whites more than blacks.
• More commonly in patients with Down’s
Syndrome.

antibiotics
• Hematologic support
2/13/2023
36
Preinduction
• Prednisolone 1mg/kg p.o for 5 days
• Recheck blast after 5 days, if blast
count dropped - good response.

CNS Proph. Methotrexate 12mg IT days 1,8,15,22
2/13/2023
CNS prophylaxis
• Given the concern of long-term neurotoxicity
and risk of brain tumors following standard
cranial irradiation, experts recommend lower
dose irradiation combined with intrathecal
administration of methotrexate.
2/13/2023 39
CNSProphylaxis
 CNS involvement at diagnosis <5%
– Without prophylaxis, over 80% of patients in CR
will relapse in the CNS
– With prophylaxis, less than 5% have CNS relapse
 Intrathecal chemotherapy is now the
mainstay
– Sample intermediate risk regimen: IT MTX
alone or “triple therapy”: IT cytarabine Day 1 of
CR followed by MTX/hydrocortisone/cytarabine

Reassess
• After 4 weeks of phase 1 induction
assess marrow for remission.
• If there is remission taper prednisolone and
after 1 week, start phase 2 induction,
• If there is no remission give 2 more weekly
doses of vincristine and doxo and then assess,
if still no remission go for alternate regimen.

years without relapse-stop chemo and follow
up.
• No relapse within 5 years -can be declared as
cured.

Allogenic stem cell transpantation
• Usually done in second remission.
• Can be done in first remission in high risk

2/13/2023
SUPPORTIVE CARE
• use of packed red cells
• When high fever and possible septicemia
occur in the presence of neutropenia,
antibiotic therapy should be started.
(NEUTROPENIA REGIME)
• Platelet transfusions should be
administered to patients with overt bleeding
or when the platelet count is below
10,000/mm3.
Nursing management
Assessment
- General condition, activity, alertness
- Pain, fever
- Bleeding
- Intake of child
- Side effects of chemotherapy
2/13/2023 49
Nursing diagnosis
1.Acute Pain related to physical agents, e.g.,
enlarged organs/lymph nodes, bone marrow
packed with leukemic cells.
2.Risk for Deficient Fluid Volume related to
decrease fluid intake and increase loss.
3.Imbalanced nutrition: less than body
requirement related to cachexia.
4.Risk for Infection related to inadequate
secondary defense.
2/13/2023 50
Nursing diagnosis
4. Activity Intolerance related to generalized
weakness and increased metabolic rate from
massive production of leukocytes.
5. Deficient Knowledge related to lack of
information.
6. Anxiety related to unfamiliar disease condition.
2/13/2023 51
Course of treatment
• The average duration of treatment in ALL is
24- 30 months, with no advantage of extending
treatment beyond 3 years.
• The outcome of ALL remains poor in infants,
even with intense therapy including stem cell
transplant.
2/13/2023 52
Late Effects of Treatment
- cranial irradiation: cognitive and intellectual
impairment and development of CNS neoplasms.
- There is a risk of secondary AML after intensive
use of epipodophyllotoxins (etoposide,
teniposide).
- Endocrine dysfunction leads to short stature,
obesity, precocious puberty, osteoporosis, thyroid
dysfunction and growth hormone deficiency.
- Patients with prior therapy with an anthracycline
are at risk of cardiac toxicity.

Acute Myeloid Leukemia
- It happens when the body makes too many
immature white blood cells. These cells,
called myeloid blasts, can't mature into normal
white blood cells.
- Because AML develops and gets worse
quickly, prompt treatment is very important.
- Of kids who have leukemia, 20% have AML.
2/13/2023 55
Clinical features
•swollen gums
•infections (like bronchitis or tonsillitis) that keep
coming back
•night sweats
•belly pain (caused by the build-up of cells in
organs like the kidneys, liver, and spleen)
2/13/2023 56
Management
- Chemotherapy: The treatment goal is remission,
which is when tests don't find any cancer cells in the
body.
- Then, maintenance chemotherapy is used to keep
the child in remission and prevent the cancer from
coming back. The child will get maintenance chemo
for 2 to 3 years.
- Stem cell transplant
2/13/2023 57
Chronic Myeloid Leukemia
- It constitute 3% of leukemias in childhood.
- It is characterized by myeloid hyperplasia of
the bone marrow, extra medullary
hematopoiesis, elevation of white blood cell
count.
2/13/2023 58
Chronic Myeloid Leukemia
Adult CML: The condition is clinically and
hematologically comparable to the adult form of
chronic myelogenous leukemia and occurs in
children above the age of 4 years.
Juvenile CML: This form presents in infancy and
early childhood, usually below the age of 4 years,
and has a more rapid course.
2/13/2023 59
Clinical features
chronic phase
- fatigue,
- malaise,
- weight loss,
- excessive sweating,
- abdominal fullness, and
- bleeding due to platelet dysfunction
- splenomegaly is usually massive.
- Symptoms of leukocytosis such as headache,
dizziness and visual disturbances.
2/13/2023 60
Treatment
Aim:
To control increasing white cell counts.
- First and second-generation oral tyrosine
kinase inhibitors (TKI) are the treatment of
choice.
- imatinib therapy.
- The starting dose of imatinib is 340 mg/ m2/
day.
2/13/2023 61
Treatment
- Bone marrow cytogenetics: 6 monthly until a
complete cytogenetic response is obtained.
- Allogeneic stem cell transplantation is
recommended for patients who do not respond
to TIU.
2/13/2023 62
Chronic Lymphocytic Leukemia
- Chronic lymphocytic leukemia (CLL) is a type
of cancer of the blood and bone marrow.
- Chronic lymphocytic leukemia most commonly
affects older adults.
- There are treatments to help control the disease.

Methotrexate 12mg IT days 1,8,15,22 2/13/2023
  • 39. CNS prophylaxis • Given the concern of long-term neurotoxicity and risk of brain tumors following standard cranial irradiation, experts recommend lower dose irradiation combined with intrathecal administration of methotrexate. 2/13/2023 39
  • 40. CNSProphylaxis  CNS involvement at diagnosis <5% – Without prophylaxis, over 80% of patients in CR will relapse in the CNS – With prophylaxis, less than 5% have CNS relapse  Intrathecal chemotherapy is now the mainstay – Sample intermediate risk regimen: IT MTX alone or “triple therapy”: IT cytarabine Day 1 of CR followed by MTX/hydrocortisone/cytarabine 4/28/2014 2/13/2023 40
  • 41. 41 Reassess • After 4 weeks of phase 1 induction assess marrow for remission. • If there is remission taper prednisolone and after 1 week, start phase 2 induction, • If there is no remission give 2 more weekly doses of vincristine and doxo and then assess, if still no remission go for alternate regimen. 2/13/2023

  • 48. SUPPORTIVE CARE • use of packed red cells • When high fever and possible septicemia occur in the presence of neutropenia, antibiotic therapy should be started. (NEUTROPENIA REGIME) • Platelet transfusions should be administered to patients with overt bleeding or when the platelet count is below 10,000/mm3.
  • 49. Nursing management Assessment - General condition, activity, alertness - Pain, fever - Bleeding - Intake of child - Side effects of chemotherapy 2/13/2023 49
  • 50. Nursing diagnosis 1.Acute Pain related to physical agents, e.g., enlarged organs/lymph nodes, bone marrow packed with leukemic cells. 2.Risk for Deficient Fluid Volume related to decrease fluid intake and increase loss. 3.Imbalanced nutrition: less than body requirement related to cachexia. 4.Risk for Infection related to inadequate secondary defense. 2/13/2023 50
  • 51. Nursing diagnosis 4. Activity Intolerance related to generalized weakness and increased metabolic rate from massive production of leukocytes. 5. Deficient Knowledge related to lack of information. 6. Anxiety related to unfamiliar disease condition. 2/13/2023 51
  • 52. Course of treatment • The average duration of treatment in ALL is 24- 30 months, with no advantage of extending treatment beyond 3 years. • The outcome of ALL remains poor in infants, even with intense therapy including stem cell transplant. 2/13/2023 52
  • 53. Late Effects of Treatment - cranial irradiation: cognitive and intellectual impairment and development of CNS neoplasms. - There is a risk of secondary AML after intensive use of epipodophyllotoxins (etoposide, teniposide). - Endocrine dysfunction leads to short stature, obesity, precocious puberty, osteoporosis, thyroid dysfunction and growth hormone deficiency. - Patients with prior therapy with an anthracycline are at risk of cardiac toxicity. 2/13/2023 53

  3. Diamond-Blackfan anemia is a disorder that primarily affects the bone marrow. Neurofibromatosis Ataxia telangiectasia (A-T) is an autosomal recessive disorder primarily characterized by cerebellar degeneration, telangiectasia, immunodeficiency, cancer susceptibility and radiation sensitivity. A-T is often referred to as a genome instability or DNA damage response syndrome. Li-Fraumeni syndrome (LFS) is an inherited familial predisposition to a wide range of certain, often rare, cancers. This is due to a change (mutation) in a tumor suppressor gene known as TP53. Bloom syndrome (BSyn) is a rare genetic disorder characterized by short stature; a sun-sensitive, red rash that occurs primarily over the nose and cheeks; mild immune deficiency with increased susceptibility to infections; insulin resistance that resembles type 2 diabetes; and most importantly, Epipodophyllotoxins are substances naturally occurring in the root of American Mayapple plant (Podophyllum peltatum).

  6. helps to clear uric acid from the blood.  Rasburicase is a medication that helps to clear uric acid from the blood. It is a recombinant version of urate oxidase, an enzyme that metabolizes uric acid to allantoin. Urate oxidase is known to be present in many mammals but does not naturally occur in humans Leukapheresis (/ˌluˈkʌfɜːriːsɪs/ ( listen)) is a laboratory procedure in which white blood cells are separated from a sample of blood. It is a specific type of apheresis, the more general term for separating out one particular constituent of blood and returning the remainder to the circulation.
  7. The goal of this to eradicated leukemia as such at the end of this phase there are <5% leukemia blasts in the bone marrow. Most children with leukemia have s subclinical CNS involvement at diagnosis, which might act aa sanctuary where blasts are protected because of the blood-brain barrier. CNS prophylaxis has enabled increase survival rates in leukemia. Intrathecal administration is a route of administration for drugs via an injection into the spinal canal, or into the subarachnoid space so that it reaches the cerebrospinal fluid (CSF) and is useful in spinal anesthesia, chemotherapy, or pain management applications.

  9. Remission means that the signs and symptoms of your cancer are reduced. Remission can be partial or complete. In a complete remission, all signs and symptoms of cancer have disappeared. If you remain in complete remission for 5 years or more, some doctors may say that you are cured
  10. Use of these medications may result in significant granulocytopenia and need supportive care.
  11. Sometimes, despite the best care and significant progress made in treatment, cancer comes back. When this happens it is called a recurrence or relapse.
