OncologyBranch of medicine that deals with the study of

tumors1 of 2 men will have cancer1 of 3 women will have cancerSecond leading cause of death in the United

StatesCancer is not one disease, but a group of

diseases characterized by the uncontrolled growth and spread of abnormal cells

Lung cancer is the leading cause of cancer-related death in both men and women

More children 14 years of age and younger die of cancer than of any other disease



Development, Prevention, and Detection of Cancer

Carcinogenesis and the primary prevention of cancer

CarcinogenesisThe process by which normal cells are transformed into cancer cells

Various factors are possible origins of cancer

CarcinogensSubstances known to increase the risk for the development of cancer


PathophysiologyMitosis (maturation and replacement)Hypertrophy (cells get larger)Hyperplasia (# of cells increase)Neoplasia

Carcinogenesis and the prevention of cancer (continued)

Risk factorsSmoking

87% of people who develop lung cancer are smokers

Dietary habitsPlay a role in development of colon,

rectum, and breast cancerExposure to radiation

Ultraviolet rays are a factor in the development of basal and squamous cell skin cancers and melanoma



Carcinogenesis and the prevention of cancer (continued)Risk factors (continued)

Exposure to environmental carcinogensFumes from rubber or dust from chloride are

examplesSmokeless tobacco

Increases the risk of cancer of the mouth, larynx, pharynx, and esophagus

Frequent, heavy consumption of alcoholMay result in oral cancer and cancer of the

larynx, throat, esophagus, and liver


Hereditary CancersAbout 90% of cancers are NOT inheritedGenetic susceptibility

Incidence of breast cancer is higher in women with a family history of this disease

Incidence of lung cancer is high in smokers with a family history of this disease

Incidence of leukemia is greater in an identical twin

Neuroblastoma occurs with increased frequency among siblings

Colon cancer is more likely to occur in women who have a history of breast cancer


Hereditary CancersCancer risk assessment and cancer genetic counselingFirst step toward identifying hereditary cancer predisposition

Provides education, health promotion, informed consent, and support


Cancer Prevention and Early DetectionPlanned periodic examination and

recognition of cancer’s warning signsColorectal testsProstate cancer detectionPelvic examination with Papanicolaou (Pap)

smear for womenBreast cancer detection (self-examinations)Skin examinations


Pathophysiology of CancerCell mechanisms and growth

Normal cellsWhen cells are destroyed, cells of the

same type reproduce until the correct number have been replenished

Cancer cellsInstead of limiting their growth to meet

specific needs, they continue to reproduce in a disorderly and unrestricted manner


Pathophysiology of CancerCell mechanisms and growth (continued)

NeoplasmUncontrolled or abnormal growth of cellsBenign: Not recurrent or progressive;

nonmalignantMalignant: Growing worse and resisting

treatment; cancerous growths; tumorsMetastasis

Tumor cells spread to distant parts of the body


FIGURE S48 Control of replication. Normal cells cannot divide indefinitely. The end of their chromosomes are controlled by telomeres. Telomeres get shorter with each division until the cells stop dividing. In cancer cells the telomerase gene is "switched on," producing an enzyme that rebuilds the telomeres. Thus the cancer cells continue to divide indefinitely.

Progression to Neoplasm


Pathophysiology of CancerDescription, grading, and staging of tumors

DescriptionCarcinoma : Malignant tumors composed of epithelial

cells; tend to metastasizeSarcoma: Malignant tumor of connective tissues, such

as bone or muscleGrading

Tumors are classified as grade 1 to grade 4 Grade 1: Mild dysplasia—cells only slightly

different from normal cellsGrade 2: Moderate dysplasia—moderately well

differentiated Grade 3: Severe dysplasia—poorly

differentiatedGrade 4: Anaplasia—cells difficult to determine

(cont.)Staging

Tumor, nodes, metastasis (TNM) staging system for cancer is used to indicate tumor size, spread to lymph nodes, and extent of metastasisStage 0: Cancer in situStage I: Tumor limited to the tissue of origin

Stage II: Limited local spreadStage III: Extensive local and regional spread

Stage IV: Metastasis



DescriptionCarcinoma: malignant tumors composed of epithelial cells; tend to metastasize

Sarcoma: malignant tumor of connective tissues, such as bone or muscle

GradingTumors are classified as grade 1 to grade 4Grade 1—least malignantGrade 4—most malignant

GRADING OF TUMORSDifferentiation:

individual characteristics of normal body cells that allow them to perform different body functions

Grading evaluates tumor cells in comparison to normal cells


Grading and StagingIndicates how far the cancer has spread anatomically

Puts patients with similar prognosis and treatment in the same group

Staging applies to all cancers except leukemia (not anatomically localized)

GRADING OF TUMORS (cont.)

The higher the grade, the higher the number and the worse the prognosis.

A grade I tumor is the most differentiated and a grade IV tumor is the most undifferentiated

Tumors containing poorly differentiated cells are more aggressive in growth and may display uncharacteristic behaviors, leading to a poorer prognosis.


GRADING OF TUMORS

Well differentiated–tumor cells that retain many identifiable tissue characteristics of original cell.

Undifferentiated–tumor cells having little similarity to tissue of origin.

Tumor grading (I-IV) is based on degree of differentiation of malignant cells.


Grading

• well differentiated (Grade 1)

• moderately differentiated (Grade 2)

• Poorly differentiated (Grade 3)

• Undifferentiated (Grade 4)

Staging Prostate CancerT1 The tumor is too small to be seen on

scans or felt during examination of the prostate. (It has been discovered by needle biopsy.)

T2 The tumor is completely inside the prostate gland

T3 The tumour has broken through the capsule (covering) of the prostate

T4 The tumour has spread into other body organs (secondary prostate cancer) nearby such as the rectum (back passage) or bladder

Cancer TherapiesChemotherapy

Side effectsLeukopeniaAnemiaThrombocytopeniaAlopeciaStomatitisNausea, vomiting, and diarrheaTumor lysis syndrome


Cancer TherapiesBiotherapy

Three major mechanisms of biological response modifiers (BRMs)1. Increases, restores, or modifies the host defenses

against the tumor2. Toxic to tumors3. Modifies the tumor biology


Cancer TherapiesBone marrow transplantation

Process of replacing diseased or damaged bone marrow with normally functioning bone marrow

Peripheral stem cell transplantationAlternative to bone marrow transplantThis procedure is based on the fact that

peripheral or circulating stem cells are capable of repopulating the bone marrow


Advanced CancerPain management

OpioidsMorphine, hydromorphone, fentanyl, methadoneSustained-release morphine

MS Contin, Roxanol SRAdministration

IV drips, intrathecally, and epidurallyAvoid peaks and valleys

Patient self-controlDistraction, massage, relaxation, biofeedback,

hypnosis, and imagery


Advanced CancerPain management (continued)

Patients should not be subjected to severe suffering from potentially controllable pain

Fear of addiction should not be a factor when considering pain relief for the terminally ill


Advanced CancerNutritional therapy

ProblemsMalnutritionAnorexia Altered taste sensationNausea/vomitingDiarrheaStomatitisMucositis


Advanced CancerCommunication and psychological support

Factors that may determine how the patient copes Ability to cope with stressful events in the pastAvailability of significant othersAbility to express feelings and concernsAge at the time of diagnosisExtent of diseaseDisruption of body imagePresence of symptomsPast experience with cancerAttitude associated with cancer


Advanced CancerTerminal prognosis

Most patients with advanced cancer know they are dying

Honesty and openness are the best approaches

Spiritual activities may provide mental and emotional strength

Social worker assists the patient and family in planning for home care

Hospice services can be arranged—efforts are directed toward relief from pain and other problems


Nursing ProcessNursing diagnoses

Coping, compromised family

Activity intolerance, related to malaise

Risk for infection, related to inflammation of protective mucous membranes

Pain, acute; Pain, chronic

Self-care deficit

Knowledge, deficient Nutrition: less than body

requirements; imbalanced, related to anorexia

Infection, risk for Fluid volume, deficient

risk for Fluid volume, excess
