Care of Patients with
Cancer

General Disease-Related Consequences of
Cancer: Nursing Diagnosis
• Impaired immune and bloodproducing function
• Altered GI structure and
function
• Motor and sensory deficits
• Decreased respiratory function
Surgery as Cancer Treatment
• Oldest form of cancer treatment used
for:
• Prophylaxis
• Diagnosis
• Cure
• Control
• Palliation
• Second-look surgery
• Reconstruction or rehabilitation
Resection of Pancreatic Tumor
Radiation Therapy for Cancer
• Purpose—to destroy cancer cells with
minimal exposure of the normal cells to the
damaging actions of radiation
• Teletherapy: radiation source outside the
body
• Brachytherapy: (opposite of teletheraphy)
the use of implants of radioactive materials
such as radium, cesium, iridium or gold at
the cancer site

Side Effects of Radiation Therapy
• Vary according to the site
• Local skin changes and hair loss that will likely be
permanent depending on the total absorbed dose
• Altered taste sensations
• Fatigue related to increased energy demands
• Inflammatory responses that cause tissue fibrosis
and scarring
Nursing Care of Patients Undergoing
Radiation Therapy
• Teach accurate objective facts to help
patient cope.
• Do not remove markings.
• Administer skin care.
• Avoid direct exposure of the skin to the
sun.
• Care for xerostomia (dry mouth).
• Bone exposed to radiation is more
vulnerable to fracture.
• Do not use lotions or ointments.
Chemotherapy
•
•
•
•
Treating cancer with chemical agents
Major role in cancer therapy
Used to cure and increase survival time
Some selectivity for killing cancer cells
over normal cells
• Normal cells most affected—the skin,
hair, intestinal tissues, spermatocytes,
and blood-forming cells
Chemotherapy
Chemotherapy Drugs
•
•
•
•
•
•
•
Antimetabolites
Antitumor antibodies
Antimitotic agents
Alkylating agents
Topoisomerase inhibitors
Miscellaneous chemotherapeutic agents
Combination chemotherapy
Treatment Issues
• Drug dosage
• Drug schedule
• Drug administration:
• Extravasation: The escape of fluids into
the surrounding tissue
• Vesicants: blistering
Side Effects of Chemotherapy
•
•
•
•
•
•
•
•
Anemia, neutropenia, thrombocytopenia
Alopecia or hair loss
Nausea and vomiting
Mucositis in the entire GI tract
Skin changes
Anxiety, sleep disturbance
Altered bowel elimination
Changes in cognitive function
Chemotherapy Patient-Centered
Nursing Care
• Infection risk
• Chemotherapy-induced nausea and
vomiting (CIN)
• Mucositis
• Alopecia
• Changes in cognitive function
• Peripheral neuropathy
Hormonal Manipulation
• Some hormones make hormone-sensitive
tumors grow more rapidly.
• Some tumors actually require specific
hormones to divide. Therefore decreasing
the amount of these hormones to
hormone-sensitive tumors can slow the
cancer growth rate.
Side Effects of Hormone Therapy
• Androgens (substances that produce male
characteristics) and antiestrogen receptor drugs
cause masculinizing effects in women.
• For men and women receiving androgens, acne may
develop, hypercalcemia is common, and liver
dysfunction may occur with prolonged therapy.
• Feminine manifestations often appear in men who
take estrogens, progestins, or antiandrogen receptor
drugs.
• Gynecomastia.
Gynecomastia
Photodynamic Therapy
• Selective destruction of cancer cells
through a chemical reaction triggered by
different types of laser light
• Patient teaching
• General sensitivity to light for up to 12
weeks after the photosensitizing drug is
injected
Immunotherapy: Biological
Response Modifiers (BRMs)
• Drugs that modify the patient’s biological responses to tumor
cells
• Cytokines—enhance the immune system they include
Interleukins & interferons (they release proteins and other cell
responses to try and prevent the unwanted cell from growing)
• Side effects—generalized and sometimes severe
inflammatory reactions, peripheral neuropathy, skin rashes
Gene Therapy
• Experimental as a cancer treatment
• Renders tumor cells more susceptible to
damage or death by other treatments
• Injection into tumor cells, enabling the
immune system to better recognize cancer
cells as foreign and kill them
• Human leukocyte antigen (HLA)
• Cytokines, IL-2
Targeted Therapy
• Combination of gene therapy and
immunotherapy
• Side effects:
• Allergic reaction
• Skin, mucous membranes, GI tract
lining
Oncologic Emergencies
• Sepsis and disseminated intravascular
coagulation
• Collaborative management includes:
• Prevention (the best measure)
• IV antibiotic therapy
• Anticoagulants, cryoprecipitated clotting
factors
Syndrome of Inappropriate Antidiuretic
Hormone (SIADH)
• Water is reabsorbed to excess by the
kidney and put into system circulation.
• SIADH is most commonly found in
carcinoma of the lung.
• Collaborative care:
• Patient safety
• Restore normal fluid balance
• Provide supportive care
Spinal Cord Compression
Spinal Cord Compression
(Cont’d)
• Collaborative management includes:
• Early recognition and treatment
• Palliative
• High-dose corticosteroids
• High-dose radiation
• Surgery
• External back or neck braces to reduce
pressure in the spinal cord
Hypercalcemia
• Occurs most often in patients with bone metastasis
• Fatigue, loss of appetite, nausea and vomiting, constipation,
polyuria, severe muscle weakness, loss of deep tendon
reflexes, paralytic ileus, dehydration, electrocardiographic
changes
• Collaborative management includes:
• Oral hydration
• Normal saline IV
• Drug therapy
• Dialysis
Superior Vena Cava Syndrome
• Superior vena cava is compressed or
obstructed by tumor growth.
• Condition can lead to a painful, lifethreatening emergency.
• Signs include edema of face, Stokes’ sign,
edema of arms and hands, dyspnea,
erythema, and epistaxis.
Superior Vena Cava Syndrome
(Cont’d)
Collaborative Care: SVC
Syndrome
• High-dose radiation therapy
• Metal stent in the vena cava
Tumor Lysis Syndrome
• Large numbers of tumor cells are
destroyed rapidly, resulting in intracellular
contents being released into the
bloodstream faster than the body can
eliminate them.
• Collaborative management includes:
• Prevention
• Hydration
• Drug therapy
Tumor Lysis Syndrome (Cont’d)
