White Blood Cells(Leukocytes)
White Blood Cells (WBC) • Formed in bone marrow and
lymphatic tissue• Destroy foreign cells via
– phagocytosis and antibody production
Granulocytes• Phagocytic cells
– produced in the bone marrow
Neutrophils• fight bacteria
Eosinophils• fight parasites • responds to allergens • influences the inflammatory process
Basophils• contain histamine• activate the inflammatory
response
Granulocytes
Agranulocytes
Participate in inflammatory and immune reactions
Monocytes (macrophages)• First line of defense in inflammatory
process• Phagocytize large cells & necrotic tissue • Important for chronic infections
Lymphocytes• Blast cells in bone marrow, spleen, thymus
and other lymph glands and tissue• Responsible for immune protection
T Lymphocytes
• T-cells – Made in thymus – Cell mediated immunity (RT an antigen)
• B cells – Humoral immunity
• “memory” cells that produce antibodies to specific antigens
• Natural killer cells– kill certain type of tumor cells and viruses
Acute Lymphocytic Leukemia (ALL)
Cancer is the 2nd cause of death <15 years
• Leukemia – malignant disease of bone marrow and lymph system
• ALL – most common form of childhood cancer– Peak onset 3-5 years of age– 80% of cases of acute leukemia in childhood– Etiology;
•Genetic abnormalities – Philadelphia chromosome (↓ prognosis)– Trisomy 21 = 20 x ↑ Risk
•Chernoble - Nuclear Radiation exposure• Alkylating agents or certain chemical
agents • Virus trigger of oncogene
ALL Pathophysiology• Abnormal, poorly differentiated blast
cells – DNA mutation of an immature white blood cell – Causes the cell to multiply uncontrollably – Infiltrate bone marrow & ↑ vascular RE organs
• Hepatomegaly• Splenomegaly • Lymphadenopathy
• Malignant blast cells replace the functioning WBC’s in bone marrow causing: Anemia (↓↓ RBCs) Neutropenia (↓↓ WBCs) Thrombocytopenia (↓↓ Plts)
Signs and symptoms1st sign: Infections that linger > 2 weeks
(↓WBC)• Fever• Chills• Anorexia• Weight loss (↑ metabolic demands of CA
cells)• Bone & joint pain (Marrow expansion)• Abdominal pain (Hepatosplenomegaly)• Pallor, fatigue, lethargy (↓ RBCs) • Ecchymosis, petechiae, GI bleeding (↓ Plts)• CNS = ↑ICP ( HA, Vomiting & Irritability)
– Late stage RT– Brain protected by blood barrier.
ALL Diagnosis • Bone Marrow Aspiration @ iliac spine• >25% blast cells = + diagnosis• Lumbar puncture (LP)
– √ any CNS involvement• PET, CT & MRI ScansGood Prognosis- Poor Prognosis• WBC <10,000/mm3 WBC >50,000/mm3 • Age 1-10 Age <1 or >10• Female Male • Early + response Poor treatment
response • No CNS involvement CNS involvement
