CANCER AND ONCOLOGICAL EMERGENCIES
Key Points
 Cancer is a neoplastic disease process that involves
abnormal cell growth and differentiation.
 The exact cause of cancer is unknown, but :



viruses,
physical and chemical agents,
hormones,
genetics, and
diet are thought to be factors that trigger abnormal cell
growth.
 Cancer cells may invade surrounding tissues and/or
spread to other areas of the body through lymph and
blood vessels (metastasis).
Key points
 Cancers may arise from the skin, bone, organs, or blood.
 Epithelial tissue; Carcinomas.
 Glandular organs; Adenocarcinomas.
 Mesenchymal tissue; Sarcomas.
 Blood-forming cells; Leukemias.
 Lymph tissue; Lymphomas.
 Plasma cells; Multiple myeloma.
 Screening and early diagnosis are the most important
aspects of care.
 Many cancers are curable when diagnosed early.
Risk Factors
 Age
 Genetic predisposition
 Exposures to chemicals, viruses, tobacco, and alcohol
 Diet high in fat and red meat, low in fiber
 Sun, ultraviolet light, or radiation exposure
 Sexual lifestyles: Multiple sexual partners, STD,
HIV/AIDS
 Other risk factors include poverty, obesity, and
chronic GERD
Diagnostic Procedures and Nursing Interventions
 Tissue biopsy – the definitive diagnosis of abnormal

cancer cells.
CBC and differential – screenings for leukemias.
Chest x-ray, CT, MRI, PET are used to visualize
tumors, metastasis, or progression of cancer.
Tumor marker assays (CEA: carcinoembryonic
antigen, CA 125: cancer antigen detected in ovarian
ca , alpha fetoprotein: elevated in ca, liver ca,
cirrhosis) – screenings that screen for cancers of the
colon, pancreas, liver, prostate, uterus, and ovaries.
Elevated values are suggestive of cancer.
Therapeutic Procedures and Nursing
Interventions
 Radiation therapy - resulting in the death of cells. Side
effects include skin changes, hair loss, and debilitating
fatigue.
 Internal radiation therapy

Client should be placed in a private room and bath.
Appropriate signage should be placed on the door
Health care personnel should wear a dosimeter film badge that
records the amount of radiation exposure.
Visitors should be limited to 30-min visits and maintain a distance of
6 ft.
Visitors and health care personnel who are pregnant or under the age
of 16 should not come in contact with the client.
A lead container should be kept in the client’s room
Precautions listed above should be carried out at home if the client is
discharged during therapy.
Therapeutic Procedures and Nursing
Interventions
 External radiation therapy
 Wash skin over irradiated area gently, with mild soap

and water, and dry thoroughly using patting motions.
Do not remove radiation “tattoos” that are used to guide
therapy.
Do not apply powders, ointments, lotions, or perfumes to
irradiated skin.
Wear soft clothing over irradiated skin and avoid tight or
constricting clothes.
Do not expose irradiated skin to sun or a heat source.
Therapeutic Procedures and Nursing
Interventions
 Surgical excision – diagnostic, curative, or palliative.

Risk of “seeding.”
Chemotherapy – a certified provider administers
systemic or local cytoxic medications to destroy rapid
dividing cells. Often, combinations of anticancer
medications are used.
The most significant adverse effect is
immunosuppression (bone marrow suppression).
Measures must be employed to reduce risk, especially at
the medications’ nadir.
Nausea and vomiting, alopecia, and mucositis are
common side effects.
Take measures to prevent extravasation of vesicants.

Antidiarrheals for GI tract.
 Mouth care for head and neck.
 Octreotide (Sandostatin) if prescribed.
 Encourage female clients to wear a hat or wig if undergoing radiation or
chemotherapy that produces alopecia (hair loss).
Listen to the client’s concerns.
Avoid false reassurance.
Provide prescribed anxiolytics if necessary.
Allow time for the client to discuss feelings regarding loss and to grieve
(mastectomy, hysterectomy, limb, lack of options for further treatment).

Complications and Nursing Implications
 Oncologic Emergencies
 Syndrome of inappropriate antidiuretic hormone (SIADH) – due
to excessive intravascular volume to increased ADH (common in
bronchogenic cancers). Monitor the client for hyponatremia and
low serum osmolality.
 Administer furosemide (Lasix), IV normal saline, and/or
hypertonic saline as prescribed for severe hyponatremia.
 Spinal cord compression – related to metastases. Assess the
client’s neurological status, including motor and/or sensory
deficits.
Administer corticosteroids as prescribed. Support the client during
radiation therapy.
Complications and Nursing Implications
 Hypercalcemia – a common complication of leukemia; breast, lung,
head, and neck cancers; lymphomas; multiple myelomas; and bony
metastases of any cancer. Symptoms include anorexia, N, V,
shortened QT interval, kidney stones, bone pain, and changes in
mental status.

Administer isotonic saline, furosemide (Lasix), and phosphates as prescribed.
 Superior vena cava syndrome – results from obstruction (for
example, metastases from breast or lung cancers) of venous return
and engorgement of the vessels from the head and upper body.


Symptoms include periorbital and facial edema, erythema of the upper body,
dyspnea, and epistaxis. Put the client in a high-Fowler’s position to facilitate
lung expansion.
High dose radiation therapy may be used for emergency temporary relief.
 Disseminated intravascular coagulation (DIC) – a coagulation
complication secondary to leukemia or adenocarcinomas.

Observe the client for bleeding and apply pressure as needed. Avoid aspirin and
NSAIDs.

in 90% of cases
History of sexually transmitted diseases (STDs)
Infection with HIV
Cigarette smoking
Immunosuppression
Intrauterine exposure to diethylstilbestrol (DES) during
pregnancy
Diagnostic Procedures and Nursing Interventions
 Pap Smear – microscopic examination of cervical
cells
 Cervical biopsy (definitive) is performed for cytologic
studies when a cervical lesion is identified.
 Biopsy is usually performed during colposcopy as a
follow-up to an abnormal Pap smear.
Therapeutic Procedures and Nursing
Interventions
 Removal of the lesion by conization
(conebiopsy), cryotherapy, laser ablation, or
loop electrosurgical excision procedure
(LEEP).
 Clients with more extensive cancer may
require a total abdominal hysterectomy or a
more extensive pelvic surgery called
exenteration (UT, GI, & Gyne; colostomy &
urostomy)
Assessments
 Monitor for signs and symptoms:

Assess/Monitor
 Pain level
 Vital signs
 Signs of infection
 Signs of disturbed body image
 The client’s understanding and expectations of
treatment
NANDA Nursing Diagnoses
 Acute pain
 Ineffective peripheral tissue perfusion
Nursing Interventions
 Treat and reverse anemia as indicated.
 Treat any pelvic, vaginal, or urinary tract infections.
 Administer pain medications as prescribed.
 Provide emotional support to the client and family.
 Prepare the client for biopsy, cryosurgery,
conization, laser therapy, LEEP, radiation, or surgery
as indicated.
Nursing Interventions
 Teach the client signs and symptoms of infection.
 Teach the client regarding home care following
special procedures (vaginal discharge, pain, avoiding
douches, avoiding sexual intercourse, safety
precautions, and post-radiation treatments).
 Refer the client to a community support group as
appropriate.
 Refer the client to counseling if depressed or
expressing concerns over sexuality.
Ovarian cancer
Ovarian cancer
 The exact etiology is unknown; however, it seems
associated with the number of ovulation (risk
increased with early menarche, late onset
menopause, nulliparity, and infertility).
 Metastases frequently occur before the primary
ovarian malignancy is diagnosed.
 The most reliable indicator of prognosis is related to
the stage of the cancer at the time of diagnosis.
Risk Factors
 Over 40 years of age
 Nulliparity or first pregnancy after 30 years old
 Family history of ovarian, breast, or colon cancer
 History of dysmenorrhea or heavy bleeding
 High-fat diet (possible risk)
 Use of baby talc (possible risk)
 Hormone replacement therapy (HRT)
 Use of infertility drugs
Diagnostic Procedures and Nursing Interventions
 Pap Smear – only abnormal in small percentage of
clients with ovarian cancer.
 Staging of ovarian cancer is determined at the time
of exploratory laparotomy
 Cancer antigen test (CA-125 antigen) is better at
measuring treatment than screening for presence of
disease.
 “Second look” surgical procedure following
treatment to determine if there is a residual tumor,
or if the cancer has been successfully treated.
Therapeutic Procedures and Nursing Interventions
 Primary interventions are:
 surgery,
 traditional chemotherapy,
 intraperitoneal chemotherapy, and
 pelvic and abdominal irradiation.
 Monitor for signs and symptoms.
