ONCOLOGY NURSING

Classification of Cancer:

Common Terminologies Oncogene  cancer genes that alter normal genes Proto oncogenes  repressed oncogene that can activated by etiologic and risk factors Anaplasia  no resemblance to tissues of origin Metaplasia  replacement of the original cell with another type of cell Carcinoma  cancer cell composed of epithelial cells that can spread Neoplasm  growth of new tissue Tumor  same with neoplasm Dysplasia  alteration in the size, shape and organization of differentiated cells Hyperplasia  an increase in the number of normal cells

Squamous cell carcinoma  surface epithelial Adenosarcoma  glandular epithelial Fibrosarcoma  fibrous connective tissue Liposarcoma  adipose tissue Chondrosarcoma  cartilage Osteosarcoma  bone Hemangiosarcoma  blood vessels Lymphangiosarcoma  lymph vessels Leiomyosarcoma  smooth muscles Rhabdomyosarcoma  striated muscles Glioma  glial cells Neurolemic sarcoma  nerve sheath Leukemia  blood

Cancer Cells Tumor can be: BENIGN Localized Encapsulated Hyperplasia, o functional activity No metastasis

Fatal if it occurs in restricted area (skull) Fully differentiated Slow growth

MALIGNANT Systemic Non encapsulated Anaplasia, metaplasia (o or q function of the organ involved) With metastasis (direct invasion, lymphatic, embolism, diffusion) Harmful Hardly differentiated Rapid growth

Cancer y y y y y y y

Synonymous to death and pain Chronic disease that has acute exacerbation Not a single disease with single cause Common in men Leading cancer is lung cancer Male: prostate Female: breast

Classification of Benign: Glandular tissue  adenoma Bone  osteotoma Nerve cells  neuroma Fibrous tissue - fibroma

Etiology Exact cause is still unknown Viruses  cancer of the liver, liv er, burkitts lymphoma Chemical Agents  tar, asphalt, arsenicals, fuels, oil Drugs  chemodrugs Physical Agents  radiation

Clients usually ignored cardinal signs of  Cancer Most often cancer is detected during routine exam uestions that need to be answered: Q uestions Example (Is the disease curable or not?)

Client Reaction during Diagnoses Client will use coping strategies to q his anxiety level such as: DenialRational inquiry-seek more information Affect Reversal-make light of the situation (laughing etc.) Mutuality-share concerns and talk with other persons Suppression-conscious forgetting Displacement or redirection-do other things y y y

Effective Test must be y y y y

Specific for the type of Cancer Reliable Economical on terms and benefits Acceptable to the client (most important)

Points to Remember y

Most

client fear of death upon confirmation of Cancer

Confrontational Redefine or revise Passive acceptance Disengagement Externalization or Projection Moral masochism Compliance and cooperational

Therapeutic

communications (silence, non  judgemental, acceptance, active friendliness, setting limits) Strategizing how to use effective coping mechanism (client and SO) Cancer management will involve surgery, radiation, chemo and immunotherapy in combination.

Surgery Used in diagnosing, staging and treating the client FNA, I&E biopsy Cytology specimens Palliative  relieves pain, airway obstruction. Reconstructive  restore maximal function and appearance Preventive  removal of target organ

y

Radiation Therapy y

o y y

y y y

y

y y y

y

Range will be 2,000-5,000 centigrays (cGy) 5,000 cGy will o SE Normal cells and cancer cells are both affected The goal is to destroy malignant cells without harming normal cells by: Fractionation-small frequent dose Alternating the site Alpha particle-fast moving helium nucleus (slight penetration) Beta particle-fast moving electron (moderate penetration) Gamma ray-similar to light ray (high penetration) Sodium Iodide (131 I)-for thyroid gland Gold (198 Au)-effective for ascites and pleural effusion Sodium Phosphate (32 P)-for RBC Destroys the ability of the cell to reproduce by damaging the DNA

Radiation Safety y

y

y y

y

Distance - the greater the distance the lesser the exposure Time - the less time spent close to radiation the less exposure (max of 30 min per shift) Shielding - use lead aprons and gloves Standards - kept as low as reasonably achievable Monitoring device - film badge (measure the whole exposure of the nurse)

Types of RADIATION External Radiation Administered by high energy xray machine (radioisotope Cobalt for Prostate and Lung CA) Internal Radiation Via injection or orally  ± 

 ± 

Internal Radiation UNSEALED SOURCE  y y y

Radioisotope is administered IV or orally NaP04 (32 P) IV for polycythemia vera (131 I) PO for Graves disease

y y y y

Potential hazard exist because its not encased Isotope maybe excreted via body fluids Flush the toilet several times after use Protect staff and visitors Marked room and kardex with RADIATION HAZARD

SEALED SOURCE  y

y y y y

radioisotope is placed into needles, beads, seeds, ribbons or catheter then implanted directly into the tumor. Requires a private room and bathroom Room must be lead-shield proof  Lead container and long forcep on bedside Check linen and other materials for the presence of isotope

Chemotherapy Use of chemicals to destroy cancer cells Interferes DNA & RNA activities associated with cell division Often used in combination with radiation therapy Cytotoxic - is an agent capable of destroying cells Cytotoxic drug - alkylating and antimetabolites y y

y

Antineoplastic Drugs Alkylating Agents Attack the DNA of rapidly dividing cell Nitrosurea: Carmustine (BCNU) Nitrogen Mustard: Chlorambucil (Leukeran) Cyclophosphamide (Cytoxan) Vinca Alkaloids Interfere with mitosis (M phase) Vincristine (Oncovin) Vinblastine (Velban) Antimetabolites Inhibits protein synthesis (S phase) Azathioprine (Imuran) Fluorouracil (5-FU) Methotrexate (Mexate) given with leucovorin to protect normal cells Antibiotics Inhibit RNA Doxorubicin HCl (Adriamycin) Mithramycin (Mithracin)

Antimetabolites Inhibits protein synthesis (S phase) Azathioprine (Imuran) Fluorouracil (5-FU) Methotrexate (Mexate) given with leucovorin to protect normal cells Antibiotics Inhibit RNA Doxorubicin HCl (Adriamycin) Mithramycin (Mithracin) Hormone Inhibit RNA and protein synthesis in tissues that are dependent on the opposite sex Androgens, Estrogens, Progestins, Steroids (Analogue, Exogenous) Hormone Antagonist: Mitotane (Lysodren) cortisol antagonist, Tamoxifen Citrate (Nolvadex) estrogen antagonist Immune Agents Introduction of an agent to stimulate production of antibodies Bacillus Calmette-Guerin (BCG)

C&R Goal: Destroy all malignant cells without excessive destruction of normal cell Control growth of tumor when cure is not possible Note: all rapid dividing cells (GI mucosa, hair follicles and bone marrow) are susceptible to the action of chemo and radiation therapy. y

y

Reasons of Combining Drugs Synergy - two or more agents works together to enhance the effect Adjuvant - an additional treatment os malignant cell destructions, qs the SE Principle of MDT is instituted to avoid and prevent the SE

C&R SIDE EFFECTS Common: nausea and vomiting Stomatitis Alopecia (2-3 weeks to occur) Bone marrow depression

Neurologic/Sensory/Perceptual Meningeal irritation CN and peripheral neuropathy Cerebellar toxicity Ototoxicity Cardiac Pericardial Effusion Arrhythmias CHF Pulmonary Pleural Effusion Pneumonitis GIT Stomatitis Esophagitis Pharyngitis Taste alteration Anorexia Nausea and vomiting Constipation and diarrhea Weight loss C&R SIDE EFFECTS GUT Nephrotoxicity Hemorrhagic cystitis Hyperuricemia Urine color changes Reproductive Loss of libido Impotence Amenorrhea Irregular menses Menopausal symptoms Azoospermia Sterility Gynecomastia Hepatic Hepatotoxicity Integumentary Alopecia Dermatitis and ulcers Hematopoietic q bone marrow activity anemia, prone to infection and bleeding tendency Metabolic TLS and Hyperkalemia

Perceived Change in Body Image Obvious reminder of disability  disability  need for prosthesis (breast, leg and eye) need for hardware (wheel chair, crutches) need for medication (CR therapy) extent of disability or limitation

Type of loss y y y y

symbols of sexuality social acceptability (colostomy) ability to communicate (laryngectomy, aphasia) anatomic changes (amputation)

Brain Tumor y

Terminally Ill y y

y y

y

50% die from the disease time from diagnosis to death ranges from weeks- years not all clients become terminally ill others die during initial treatment; others die from complications of treatment Endpoint: no response to treatment and progressions cannot be controlled

HOSPICE CARE y

y y y y y

standard of care for terminally ill cancer clients symptom control pain management providing comfort and dignity 24 hour  7 day coverage services are given based on clients need not on its ability to pay

y

y

y

y

caring can be just successful as curing; when curing is not an option care is exercised during the final stage of  life

Goals of Intervention y

y

to care without functional and structural impairment if cure is not possible goals must = prevent further metastasis = relieve symptoms = maintain high quality of life
