Oncology
• Biology of abnormal cancer cells
• They have continuous or inappropriate,
usually faster growth or larger growth
patterns
• They have no specific morphology and
often do not resemble their parent cells
= anaplastic
• They do not respond to signals for
apoptosis = programmed cell death
Oncology
• Biology of abnormal cancer cells
• Have a large nuclear – cytoplasmic
ratio; the nucleus may occupy most of
the cell area
• They lose some or all of their normal
cell functions
• They do not make fibronectin, and
thus cannot connect easily and break
off easily
Oncology
• Biology of abnormal cancer cells
• They are able to migrate throughout the
body = metastasis
• They invade other tissues and types of
cells.
• They are not controlled by contact
• They have more or less chromosomes
than the parent cells = aneuploid
or a mutation of the genes
Oncology
• Cancer development
• Initiation – there are many
theories as to when the genes in
the cells are damaged, maybe in
utero, from physical or chemical
exposure, latent oncogenes,
viruses, or a lack of suppressor
genes from our parents, and at
this point the cell is not dividing.
Oncology
• Skin cells
Oncology
• Cancer development
• Promotion - the stage when the
abnormal cell starts to divide, may
be stimulated by environmental
changes, hormones, drugs, or
irritants
Oncology
• Cancer development
• Progression – the phase when
the abnormal cells have continued
to grow into a Primary tumor, may
produce angiogenesis factors
which supply blood and vascular
nourishment to the tumor. The
tumor may have subcolonies of
cells with different genes and
features
Oncology
• Cancer development
• Metastasis
the movement of cancer cells into
other organs of the body, thus
creating new tumor sites.
Oncology
• Cancer grading and staging
• Cancer is graded upon the resemblance to
normal cells = G
(The higher the number, the worse the grade of
cancer) i.e. G1, G2, G3, G4
•
•
•
•
•
Staging is based upon
the presence of a primary tumor = T
involvement in lymph nodes = N
and appearance of metastasis = M
Numbers of the stage range from
x = none to 3 or 4 for each letter
Oncology
• Is this a high grade or low grade
cancer?
• Case study
Julie has a breast lump in her right
breast, and has also found one in her
right armpit. Biopsy and lumpectomy
were performed. The tumor was
graded G3, T2, N2, M1.

• Julie opted to have a lymphectomy
of her right arm lymph nodes, and
started radiation treatment right
away. Her doctor also suggested
that she start Adriamycin IV
chemotherapy to get any cells that
the radiation might miss.

to compress nerves or organs
• Lymphadema – when the tumor blocks
lymph or circulatory flow
• Motor or sensory deficits
Oncology
• The 60 year old client with small cell lung cancer
is concerned that his grown children also might
develop the disease. What is the nurses best
response?
– A. “This disease is a random event
and there is no way to prevent it.”
– B. “Because this disease is inherited as a
dominant trait, your children have a 50% risk
for developing it.”
– C. “Cigarette smoking is the main cause of this
disease, and helping your children not to
smoke will decrease their risk.”
– D. “ Lung cancer can be avoided by decreasing
dietary intake of fats and increasing the
amount of regular aerobic exercise.”

Oncology
• Nursing interventions for radiation
TX
• Assess incidence and severity of side
effects
• Maximize radiation protection, all
wastes will be radioactive if isotopes are
injected
• Shielding for staff
Oncology
• Malignant Lymphomas – 2 types
• Hodgkin's Lymphoma – most common
cancer in 10 to 20 year olds (young
adults). Associated with an inflammatory
process related to +EBV/mono infection.
• Diagnosis: Classic Reed-Steinberg cell
with two mirrored nuclei, CT scan
• Symptoms: Extreme fatigue, enlarged
lymph nodes that are painless. May
progress to weight loss fevers, night
sweats
Oncology
• Malignant Lymphomas – 2 types
• Hodgkin's Lymphoma
• Treatment – combined radiation
and chemotherapy, stem cell
transplants if resistant type or
recurring
• 85% curable
• (90% in some institutions)
Oncology
• Malignant Lymphomas – 2 types
• Non-Hodgkins Lymphoma – 3 times
more common than Hodgkin’s
lymphoma, can either be T-cell
lymphomas, or B-cell lymphomas
• Can be low grade or high grade disease.
B-cell lymphomas = 50% and usually
are more aggressive tumors. Since they
grow faster, they are also more sensitive
to radiation and chemotherapy
Oncology
• Malignant Lymphomas – 2 types
• Non-Hodgkins Lymphoma
• Diagnosis: bone marrow biopsy, CT
scan, lymphoma panel with CD markers
• Symptoms- adenopathy, spleenomegaly
with vague abdominal pain, back pain,
and since immunity B or T-cell function is
affected- the patient is more prone to
infections. Subcutaneous T-cell
lymphoma is a classic discoid rash on the
upper body and trunk that does not
respond to steroids or creams.
• NHL can progress rapidly to leukemia if
untreated.
Oncology
• Malignant Lymphomas – 2 types
• Non-Hodgkins Lymphoma
• Treatments: Monoclonal
antibodies, chemotherapy with
Fludara/Fludarabine, radiation
therapy, and bone marrow implants
Oncology
• Leukemia– hematopoeitic cancer
of the stem cells. These stem cells
proliferate into non-functional
immature white cells.
• More children get leukemia than
any other type of cancer and it is
the #1 cause of death in children.
• Anyone can get leukemia at any
age.
Oncology
• Leukemia -4 types
•
•
•
•
•
Acute lymphoblastic leukemia (ALL)
Acute myelogenous leukemia (AML)
Chronic Lymphocytic leukemia (CLL)
Chronic myelogenous leukemia (CML)
Anagram – ALL AniMals are CLearLy
CaMeLs
Oncology
• Leukemia –ALL suspected cause is a
T-cell virus (HTLV-1) – 85% is seen in
children, 25% in adults 30-to-40 y.o.
• Diagnosis: peripheral blood smear
after abnormally high white count, bone
marrow biopsy shows lymphoblasts
>50%m may have decrease in
platelets. Lumbar puncture to
determine CSF involvement
Oncology
• Leukemia –ALL
• Symptoms – fatigue, anorexia,
malaise, weight loss, bleeding,
infections, headaches, adenopathy,
spleenomegaly, gingival hypertrophy,
hepatomegaly, bone or joint pain
• Treatment: complete response is a
bone marrow aspirate with < 5%
blasts. Chemotherapy – vincristine,
prednisone, danorubicin, methotrexate,
• Maintenance therapy – 6 weeks of
• 6-mercaptopurine and methotrexate
low dose therapy
Oncology
• Leukemia – AML – more common in
patient’s with chromosomal genetic
disorders, exposure to benzene or
radiation. Use of alkylating agents for
breast, ovarian, or myeloma are
associated with a later malignancy of
this type.
• Symptoms- are like ALL with the
additions of anemia, thrombocytopenia,
visual disturbances, epistaxis
(nosebleeds), headache with vomiting,
dysphagia, papilladema, menorrhagia
(lots more bleeding problems)
Oncology
• Leukemia – AML
• Diagnosis: peripheral blood
smear shows Auer bodies (rods),
platelets less than 20,000/mm3,
bone marrow biopsy
• Prognosis – poor prognosis if
patient has already received
radiation or chemotherapy, or has
a WBC >100,000
Oncology
• Leukemia – AML
• Treatment: Cytaribine
chemotherapy in combination
therapy with Danorubicin or
doxirubicin, works 65% of the
time.
• Bone marrow transplant or stem
cell transplant.
Oncology
• Leukemia – CLL – staged 0-5
• chronic diseases have more mature
cells, majority of CLL is B-cell
proliferation – 95%. Only 5% are Tcells, more common in people with
autoimmune diseases, i.e. SJogren’s,
SLE, hemolytic anemia
• Symptoms: skin and respiratory
infections, fatigue, thrombocytopenia,
anemia, spleenomegaly
Oncology
• Leukemia – CLL
• Diagnosis- peripheral blood
smear, bone marrow biopsy
• Treatments: Gleevac – drug of
choice; chemotherapy in
combinations, spleenectomy,
radiation therapy to spleen, bone
marrow transplant, stem cell
transplants
Oncology
• Leukemia – CML (last is the CaMeL)
- More common after radiation exposure,
benzene exposure, less common than the
other types of leukemia, and occurs most
often between 50-60 y.o.
• Diagnosis: hallmark is the presence of
the Philadelphia Chromosome,
Chromosome #22 is missing part of the
long arm which is translocated to
Chromosome #9. This is present in 95%
of those patients with CML.
• WBC >100,000 with proliferation of all
types of mature and immature white cells.
• Bone marrow biopsy
Oncology
Leukemia – CML
• Symptoms: same as other leukemias
with chronic fever, sternal tenderness
and dyspnea – usually due to severe
anemias
• Treatments: chemotherapy with
Bisulfan and hydroxurea, other
combination chemos,
• Interferon alpha 2b to suppress the
expression of the Philadelphia
chromosome.
• Bone marrow transplant or stem cells
Oncology
• Bone marrow and stem cell implants
New treatments for:
Acute myelogenous leukemias (AML)
Acute lymphoblastic leukemias (ALL)
Myelodysplasia syndromes (MDS)
Chronic myelogenous leukemias that do not
respond to chemotherapy (CML)
Blast crisis
Pediatric acute leukemias
Non-Hodgkins lymphoma
Large B-Cell lymphoma
Multiple myelomas
Bone marrow and stem cell
implants
Oncology
• Bone marrow and stem cell
implants
• Procedure= multiple punctures
• Marrow acquisition from donor or
when patient is in remission, or stem
cells from umbilical blood of a
matching sibling or family member
• Marrow is filtered to purge tumor
cells, fat and bone particles, then place
in a blood bag for cryopreservation.
Oncology
• Bone marrow and stem cell
implants
Preparing Recipient:
• Marrow recipient is given high dose
chemotherapy alone or in combination
with radiation to suppress immune
system, open spaces in the marrow,
and kill remaining cancer cells.
• Bone marrow is thawed and infused
through a central venous catheter
Oncology
• Bone marrow and stem cell
implants
Preparing Recipient:
• Stem cells are infused after thawing
• Post-procedure:
• Patient is supported through the period
of aplasia, 10 to 30 days, while in
reverse isolation and on graft
immunosuppressants,
• Observed for signs of Graft-versushost disease and/or infection
Oncology
• The waves of the future:
• Stem Cell Research
• Oncogene therapy – now that cancer
cells are being genetically tagged, we
can tell which growth factors are
present, and which enzymes turn off
the gene. Soon all gene markers will
have a pill that matches the enzyme,
i.e. IRESSA is a tyramine kinase
inhibitor, and stops the tumors growth
that use tyramine kinase
Oncology
• Stem Cell Induction – there are new
drugs out for stem cell induction to
immunosuppress the patient, even in
deadly cancers, i.e. Multiple
Myeloma. Recently, the combination
of lenalidomide(Revalamid),
bortezomib (Velcade) and
dexamethasone produced a
98% response rate in patients
Oncology
• The waves of the future:
• Cancer vaccines
• Oncology is the science of cancer
and treatment of all cancer
patients. It is one of the most
demanding and rewarding fields in
medicine.
• The future is open for a cure.
