MAIN CATEGORIES OF CANCER
PAGE 1 OF 22
Interphase - 90% growth, DNA replication, cell func.
G0 - resting stage. Cell leaves to carry out function
Carcinoma: cancer that begins in the skin or in tissues
that line or cover internal organs
Sarcoma: begins in bone, cartilage, fat, muscle, blood
vessels, or connective/supportive tissues.
Leukemia: begins in blood forming tissue, such as
bone marrow, and causes large numbers of abnormal
blood cells to be produced and enter the blood.
Lymphoma and myeloma: begins in cells of the
immune system, bone marrow
CNS cancers: begin in tissues of the brain and spinal
cord; ex: nerve cells: neuroblastoma
Classification of Cancer
According to behavior of tumor
• Benign:
• tumors that cannot spread by invasion or
metastasis; hence they only grow locally
• Malignant:
• capable of spreading by invasion/metastasis.
• Metastases share name of the primary tumor
• Spread to vital organs (liver, brain) — life
threatening
•
•
•
•
Healthy cells
Large cytoplasm
Single nucleus
Single nucleolus
Fine chromatin
•
•
•
•
Cancerous cells
Small cytoplasm
Multiple nuclei
Multiple and large
nucleoli
Coarse chromatin
CELL PARTS & CYCLE
Nucleus- control center; controls genetic info
Mitochondria- powerhouse; converts sugar to energy
via cellular respiration.
Ribosomes- site of protein synthesis
Golgi apparatus- packaging center of cell; packages
& secretes proteins
Centrioles- organizes microtubules (spindle fibers) for
mitosis
Chromosomes- condensed DNA and proteins, codes
for genetic traits
Endoplasmic Reticulum- Transports intracellular
materials.
Cell cycle
G1- growth and prep of chromosomes for replication
S phase- DNA replication occurs
G2- prepare for mitosis
M phase- mitosis occurs 10%
• Prophase: chromosomes condensing; nucleus
present
• Metaphase- chromosomes line up in middle of cell;
nucleus dissembled
• Anaphase- chromosomes move away to opposite
sides via spindles
• Telophase - new nuclei forms on both sides to form
new cells.
• Cytokinesis- splits cells into 2.
Cell cycle quality control:
• Checkpoints in G1 & G2
• Apoptosis: self destruction of cell
• Mitosis checkpoints: detect failure of spindle fibers
& arrest cell in metaphase.
• Gene mutations = checkpoint failure = cancer
CANCER
Gene mutations:
1. Tumor suppressor gene mutations: Cancer cells
avoid apoptosis and keep growing and dividing,
resulting in a tumor. This is a recessive mutation
so both alleles in the gene need to be mutated to
cause the cancer.
“brakes of a car”
2. Proto-oncogene mutations: dominant genes, only
one allele needs to be stated to cause cancer.—
proto-onco gene mutates into an oncogene, a cell
will keep diving even when there are no messages
to divide.
“gas of a car”
Abnormal cell growth —> Tumor/neoplasm formation
—> apoptosis fails —> Invasion & Metastasis
Invasion: direct migration and penetration by cancer
cells into neighboring tissues
Metastasis: ability of cancer cells to penetrate into
lymphatic and blood vessels, circulate through the
DANE DELION
BSN 3
bloodstream, and then invade normal tissues elsewhere
in the body.
Establishment and growth: tumor cells established
and grow in secondary site: lymph nodes or in organs
from venous circulation
Carcinogenesis Stages:
1.
Initiation: carcinogens cause mutations in the
cellular DNA.
• Spontaneous
• Carcinogens: chemicals, physical factors,
biologic agents
2. Promotion: allow a cell that has undergone
initiation to become cancerous. (Doesn’t affect cells
that haven’t undergone initiation). Leads to the
formation of pre-neoplastic or benign lesion.
• Drugs
• Sex hormones
3. Spread/Progression: cancer grows into
surrounding tissue or organs (stimulate angiogenesis) ,
nearby or distant. Spread via lymphatic system or
blood stream.
• Proliferation— rapid reproduction by cell
division: hyperplasia, dysplasia, and
metaplasia, neoplasia
• Metastasis — spread or transfer of cancer
cells

PATHOPHYSIOLOGY
Abnormal cell formed by mutated DNA
↓
Cells grow and proliferate
↓
Metastasis occurs when abnormal cells invade other
tissue through lymph and blood
(cancer dev linked to immune system failure)
Ways the tumor cells evade the immune system:
• Don’t present with Tumor assoc. antigen(TAA)
• Altered cell membranes (genetic mutations)
• Induce T-lymph anergy/tolerance
• Block killing of tumor
• Induce cell death of the lymphocyte
• Release cytokines
• inhibit antigen presenting cells (APCs)
• Over expression of suppressor T lymphocytes
permits uncontrolled cell growth
• Low levels of antibodies
• Impairs proliferation of helper T-cells
• Combine with antibodies to hide from the normal
immune defense mechanism

• Dx:
• CXR
• CT scan
• MRI
• Histology
• Venogram
• Tx:
• Emergency: stent and radiation therapy
• Non-emergency: histology diagnosis &
appropriate treatment (chemotherapy, other
medications: thrombolytics, anticoagulants)
• Supportive measures O2 therapy,
corticosteroids, diuretics
• Nursing Management:
• Identify pt at risk for SVCS: non-small cell lung
cancers, lymphomas, mediastinal metastases
from breast cancer.
• Provide pt education regarding s/sx to report
• Monitor cardiopulmonary and neurologic status
• Semi fowler position
• Monitor pt’s fluid volume status
• Avoid upper extremity venipuncture and BP
measurement; instruct pt to avoid tight or
restrictive clothing
• Spinal Cord Compression: spinal cord becomes
compressed at the thoracic, cervical, or sacral level
by a tumor.
• Often associated by cancers that metastasize to the
bone: breast, lung, prostate, lymphoma,
nasopharyngeal, and multiple myeloma.
• S/sx:
• Inflammation
PAGE 21 OF 22
• Back/neck pain
• Worsened by: movement, supine recumbent
position, coughing, sneezing, or valsalva
maneuver.
• Numbness, tingling
• Motor loss
• Bowel/bladder dysfunction
• Dx:
• Percussion at level of compression
• Abnormal reflexes
• Sensory and motor abnormalities
• MRI, bone scan, CT scan
• Tx:
• Radiation
• surgery— debulk the tumor
• Vertebral augmentation
• Vertebroplasty
• Kyphoplasty
• Chemotherapy
• Nursing Management:
• Asses neurologic function
• Control pain with pharmacologic and non
Pharma methods
• Prevent complications from immobility
• ROM exercise
• Urinary catheterization
• Provide encouragement and support
• Hypercalcemia: excess calcium in the blood,
kidneys cannot excrete it fast enough, bones can’t
reabsorb it.
• Results from cytokine release, hormonal
substances, and growth factors released by
cancer cells.
• Breast, lung, renal cancer, myeloma, and
leukemias.
• S/sx:
• Fatigue
• Weakness
• Confusion
• Hyporeflexia
• Polydipsia
• Dehydration
• Dysrhythmias
• Dx: serum calcium test > 10.5 mg/dL
• Ionized serum calcium > 1.29 mmol/L
• Tx:
• Identify patients at risk for hypercalcemia
• Educate pts and family
• Need to consume 2-4L fluid daily unless CI
• Promotion of mobility and importance of
preventing demineralization and breaking down
of bones.
DANE DELION
• Tumor lysis syndrome: the release of intra-tumor
cellular contents into the blood stream that lead to
electrolyte imbalances (hyperkalemia,
hyperphosphatemia, hypocalcemia) which have end
organ effects on heart, kidneys, and CNS.
• Lung cancer, leukemia, lymphoma
• S/sx:
• Acute kidney injury (creatinine > 1.5 times
upper limit of normal)
• Dysrhythmias
• Seizures
• Neuro: fatigue, weakness, memory loss, altered
mental state, muscle cramps, tetany
• Cardiac: HTN, dysrhythmias, cardiac arrest
• GI: anorexia, N/V, abdominal cramps, increased
bowel sounds
• Renal: flank pain, oliguria, anuria, acidic urine
pH
• Other: gout, malaise, pruritis
• Dx:
• Serum electrolyte levels
• Urinalysis
• ECG to detect cardiac changes
• Tx:
• Aggressive fluid hydration
• Diuretics (loop diuretics)
• Allopurinol
• IV sodium bicarb.
• Hemodialysis
• Nursing management:
• Identify at risk patients
• Assess for s/sx of electrolyte imbalances
• Assess urine pH to confirm alkalization
• Monitor serum electrolyte and uric acid levels
