What is cancer?
• Normal cells grow and divide, then
eventually die.
• Cancer occurs when the body is
unable to regulate cell growth,
leading to an overgrowth of abnormal
cells.

Malignant
Benign v. Malignant
• Benign: overgrowth of cells that are
NOT cancerous
• Malignant: overgrowth of cells that
ARE cancerous
Pediatric Oncology Facts
• In the U.S., cancer remains responsible
for more deaths from one year through
adolescence than any other disease; more
deaths than asthma, diabetes, cystic
fibrosis and AIDS combined.
• Each year in the U.S., approximately
12,500 children and adolescents are
diagnosed with cancer. That’s the
equivalent of two average size classrooms
diagnosed each school day.
Pediatric Oncology Facts
• In the early 1950s, less than 10
percent of childhood cancer patients
could be cured.
• Today, nearly 80% of children
diagnosed with cancer become longterm survivors and the majority of
them are considered cured.
Pediatric Oncology Facts
• Most common childhood cancers:
-leukemia (blood)
-brain and nervous system
-the lymphatic system (lymphoma)
-kidneys (Wilm’s tumor)
-bones (osteosarcoma & Ewing’s
sarcoma)
-muscles (rhabdomyosarcoma)

adhering to

(depending on

Means of diagnosis
• Well child check-ups (physical assessment
& review of symptoms)
• Blood tests
• Radiology exams (x-rays, CT, MRI)
• Pathology (biopsy of mass)
• Diagnostic procedures
-Bone marrow aspirate
-Bone marrow biopsy
-Lumbar puncture
Bone Marrow Aspiration
Methods for treatment
• Depends of type and stage of
malignancy
• Includes the following:
-Chemotherapy
-Radiation
-Surgical resection
-Stem cell transplantation
Chemotherapy
• Chemotherapy can be delivered by the
bloodstream to reach cancer cells all over the
body, or it can be administered directly to
specific cancer sites.
• Chemotherapy can be given through various
methods:
-intravenously (IV)
-intrathecally (IT)
-intramuscularly (IM)
-subcutaneously (SQ)
-orally (PO).
Chemotherapy
• Works by interfering with the ability
of cancer cells to divide and
reproduce themselves.
• Attacks all rapidly dividing cells.
Rapidly dividing cells:
•
•
•
•
Hair
Skin
Nails
Blood cells
-Red blood cells
-White blood cells
-Platelets
Three blood lines
• Red blood cells:
-carry oxygen to surrounding tissues
• White blood cells:
-fight off infection
• Platelets:
-help to prevent excessive bleeding;
assists in clot formation
Complications of
chemotherapy

•
Anemia (low RBC)
Thrombocytopenia (low platelet)
Neutropenia (low WBC)
INFECTION
Hair loss
Mouth sores (mucositis)
Nausea, vomiting & diarrhea

The Faces of Childhood
Cancer
• The Faces of Childhood Cancer
WHY this profession?
• LOVE KIDS!!!!!!
• Hem/Onc - Increased acuity than med/surg units
 mentally challenging each day; pathophysiology
is complex in this population
• Opportunity to INVEST in PEOPLE
• Develop long-term relations with patients
• See effects of my efforts over time
• End of life care
• Working 3 days/week = Full time!!!
What is my day like?
• 12 hour shifts; 7am – 7pm
• Nurse: patient ratio = 1:3 max
• Manage care for each assigned patient, which may include,
but not limited to: medication administration, IVF, chemo
(monitoring/managing side effects), blood products,
procedures (including sedation) for BMA & LP, bone marrow
transplant infusions, monoclonal antibodies, ng
placement/feeds, IV access, obtaining & monitoring labs,
coordinating with other disciplines (PT/OT, speech therapy,
radiology, OR) … being PROACTIVE in patient care, focusing
on management while preventing further
issues/complications.
And the numbers are …
• Starting salary: $21.49/hr (CMH in top 5%
salary for RN’s in KC area)
• Shift differentials: 10% evening (311:30pm), 15% nights (7p-7a), 10%
weekend
• Specialty differentials: 10% critical care,
5% OR, SDS, PACU, $1.00/hr for approved
specialty certifications
