It is a proliferation of abnormal WBCs
Leukemia
The most common leukemia in children is
acute lymphocytic leukemia (ALL)
is a proliferation of blast cells (immature lymphocytes.
Acute Lymphocytic Leukemia
ALL is classified by?
Form, Structure and morphology of the blast cells
Leukemia may be diagnosed at any age but has a peak onset between
3 and 5 years of age
environmental factors of leukemia
chemicals and radiation
genetic diseases have been associated with increase of leukemia?
Down Syndrome, Fanconi anemia and Bloom syndrome.
pathophysiology of leukemia
Malignant leukemia cells arise from precursor cells in blood-forming elements.
These cells can accumulate and crowd our normal bone marrow elements, spill peripheral blood, and eventually invade all body organs and tissues.
Replacement of normal hematopoietic elements by leukemic cells results in bone marrow suppression, which is marked by a decreased production of RBCs, normal WBCs, and platelets.
Bone marrow suppression results in anemia from decreased RBC production, predisposition to infection due to neutropenia, and bleeding tendencies due to thrombocytopenia. These put the child at risk of death from infection or hemorrhage.
Infiltration of reticuloendothelial organs (spleen, liver, and lymph glands) causes marked enlargement, and eventually, fibrosis.
Leukemic infiltration of the CNS results in increased intracranial pressure (ICP) and other effects, depending on the specific areas involved.
Other possible sites of long-term infiltration include the kidneys, testes, prostate, ovaries, GI tract, and lungs.
The hypermetabolic leukemic cells eventually deprive all body cells of nutrients necessary for survival. Uncontrolled growth of leukemic cells can result in metabolic starvation.
Clinical manifestations of anemia
– fatigue, pallor, tachycardia
Clinical manifestation of leukemia
a. Anemia – fatigue, pallor, tachycardia
b. Bleeding which includes petechiae, purpura, hematuria, epistaxis, and tarry stools
c. Immunosuppression – fever, infection, poor wound healing
d. Hepatosplenomegaly, bone pain, and lymphadenopathy
e. CNS symptoms (if there is CNS metastasis) – headache, meningeal irritation, and signs of increased ICP.
f. General symptoms: weight loss, anorexia, vomiting
what are the laboratory findings and diagnostic study findings
a. CBC may reveal normal, decreased, or increased WBC count with immature cells (blasts), decreased RBCs, and decreased platelets.
b. Bone marrow aspiration confirms the diagnosis by revealing extensive replacement of normal bone marrow elements by leukemic cells.
c. Lumbar puncture assesses abnormal cell migration to the CNS.
Nursing Diagnoses
- Risk for injury
- Risk for infection
- Risk for trauma
- Risk for fluid volume deficit
- Altered nutrition: less than body requirements
- Altered oral mucous membranes
- Pain
- Risk for altered growth
- Risk for altered development
- Altered family processes
- Anticipatory grief
- Assist in ensuring partial or complete remission from the disease by administering ?
administering chemotherapy and by preventing or minimizing, the complications of chemotherapy, radiation, and bone marrow transplant (BMT).
What are the complication of BMT in the GI tract
nausea, vomiting, anorexia, diarrhea, mucositis
What are the complication of BMT in the renal
Hypovolemia, hypoproteinemia, dehydration, septic shock
what are the - Interstitial pneumonia and - Graft rejection or failure complications
fever, infection, decreased blood count
is a malignant neoplasm of the kidney.
Wilm’s tumor
. It is the most common intraabdominal tumor in children
Wilm’s tumor
the most curable solid tumor in children
Wilm’s tumor
The median age at diagnosis is between? (wilm’s tumor)
2 and 3 years old.
Wilm’s tumor is , it is unilateral and occurs with other abnormalities such as an
absent iris or genitourinary problems.
Pathophysiology of wilm’s tumor
The tumor originates from immature renoblast cells located in the renal parenchyma.
It is well encapsulated in early stages but may later extend into lymph nodes and the renal vein or vena cava and metastasize to the lungs and other sites
Five stages of wilms tumor
a. Stage I: tumor is confined in one kidney
b. Stage II: the tumor extends beyond kidney but can be resected
c. Stage III: the tumor has residual nonhematogenous tumor cells confined to the abdomen.
d. Stage IV: The tumor is characterized by distant metastases involving lung, liver. Bone, or brain.
e. Stage V: the tumor involves both kidneys
what is the common sign of wilms tumor
Abdominal mass
