Week 3; Cancer Care Flashcards

1
Q

Malignant cells

A

BNORMAL, SERVE NO USEFUL FUNCTION, AND ARE
HARMFUL TO NORMAL BODY TISSUES. MALIGNANT TRANSFORMATION IS WHEN A NORMAL CELL CHANGES INTO A CANCER CELL.

Q

Cancer cells often have these characteristics

A

1) ANAPLASIA – LOSS OF SPECIFIC APPEARANCE OF
THEIR PARENT CELLS, CANCER CELL BECOMES MORE
MALIGNANT, IT BECOMES SMALLER AND ROUNDED,
LOOK ALIKE UNDER A MICROSCOPE
2) LARGER NUCLEAR-CYTOPLASMIC RATIO - NUCLEUS
LARGER THAN NORMAL CELL
3) SPECIFIC FUNCTIONS LOST
4) LOOSE ADHERENCE – EASILY BREAK OFF FROM TUMOR

Q

Metasitasis

A

CELLS MUST PENETRATE BLOOD VESSELS TO SPREAD TO DISTANT ORGANS AND TISSUES. BLOODBORNE
METASTASIS IS THE MOST COMMON. CELLS ALSO TRAVEL THROUGH LYMPH TO INVADE OTHER TISSUES AND ORGANS. METASTASIS OCCURS WHEN CANCER CELLS MOVE FROM PRIMARY LOCATION BY BREAKING OFF FROM THE ORIGINAL GROUP AND ESTABLISHING IN REMOTE AREAS.

Q

PROSTATE AND TESTICULAR CANCER

A

ONE OF THE MOST COMMON TYPES OF CANCER. MANY PROSTATE CANCERS GROW SLOWLY AND ARE CONFINED TO THE PROSTATE GLAND, WHERE THEY
MAY NOT CAUSE SERIOUS HARM. SOME TYPES
GROW SLOWLY AND MAY NEED MINIMAL OR EVEN
NO TREATMENT, OTHER TYPES ARE AGGRESSIVE.

* TROUBLE URINATING
* DECREASED FORCE IN THE STREAM OF URINE
* BLOOD IN THE URINE

Q

PANCREATIC CANCER DX

A
  • BY SYMPTOM AND TESTING, NO SCREENING
  • RADIOLOGY – CT, MRI, PET, ULTRASOUND
  • BIOPSY
  • CARCINOEMBRYONIC ANTIGEN (CEA) AND CA 19-9, ARE ELEVATED IN PEOPLE WITH PANCREATIC CANCER.
    HOWEVER, BLOOD TESTS DON’T ALLOW FOR EARLY
    DETECTION OF PANCREATIC CANCER, BECAUSE THESE
    LEVELS MAY NOT RISE UNTIL PANCREATIC CANCER IS
    ADVANCED, IF AT ALL.

* IONIZING RADIATION
* EXPOSURE—AMOUNT OF RADIATION DELIVERED
* RADIATION DOSE—AMOUNT OF RADIATION ABSORBED

23
Q

PART OF THE MULTIDISCIPLINARY
TEAM - DOSIMETRIST

A
  • USE TREATMENT PLANNING SOFTWARE TO HELP THE
    RADIATION ONCOLOGIST DEVELOP A TREATMENT PLAN
  • CONTOURS ARE CREATED FOR NORMAL TISSUES, SUCH AS THE LUNGS OR LIVER AND FOR TUMOR STRUCTURES AND OTHER AREAS AT RISK FOR HARBORING CANCER CELLS.
  • CALCULATE THE DOSE OF RADIATION THAT WILL BE
    DELIVERED TO THESE CONTOURED STRUCTURES TO MAKE SURE THAT THE TUMOR GETS ENOUGH RADIATION TO DESTROY IT WHILE SPARES THE NORMAL TISSUES.
  • THERE ARE GENERALLY ACCEPTED GUIDELINES (DOSE
    CONSTRAINTS) FOR THE AMOUNT OF RADIATION THAT A PARTICULAR ORGAN CAN TOLERATE.
24
Q

Role of oncology nurse r/t radiation

A
  • WORK WITH THE RADIATION TEAM TO CARE FOR
    PATIENTS DURING THE COURSE OF TREATMENT.
  • HELP EVALUATE THE PATIENT BEFORE TREATMENT
    BEGINS.
  • EDUCATE HE PATIENT ABOUT POTENTIAL SIDE EFFECTS AND THEIR MANAGEMENT.
  • DURING THE COURSE OF RADIATION TREATMENTS, THE NURSE MAY EVALUATE THE PATIENT WEEKLY OR MORE FREQUENTLY TO ASSESS PROBLEMS AND CONCERNS.
25
Q

Side effects of radiation therapy

A
  • ACUTE AND LONG-TERM SITE-SPECIFIC CHANGES
  • VARY ACCORDING TO SITE
  • LOCAL SKIN CHANGES AND HAIR LOSS
  • ALTERED TASTE SENSATIONS
  • FATIGUE
  • BONE MARROW SUPPRESSION
26
Q

Interprofessional collaborative care

A
  • PROVIDE ACCURATE INFORMATION
  • DO NOT REMOVE TEMPORARY INK MARKINGS
  • AVOID SKIN IRRITATION
  • FOLLOW POLICY FOR SKIN CARE PRODUCT USE
  • NUTRITIONAL SUPPORT
  • CARE FOR XEROSTOMIA
  • TEACH ABOUT RISK FOR FRACTURES
  • FOR BONE EXPOSED TO RADIATION
  • EXERCISE AND SLEEP INTERVENTIONS FOR FATIGUE
27
Q

Teaching points

A
  • HAVING RADIATION THERAPY SLIGHTLY INCREASES THE RISK OF DEVELOPING A SECOND CANCER. BUT FOR
    MANY PEOPLE, RADIATION THERAPY ELIMINATES THE EXISTING CANCER. THIS BENEFIT IS GREATER THAN THE
    SMALL RISK THAT THE TREATMENT COULD CAUSE A NEW CANCER IN THE FUTURE.
  • DURING EXTERNAL-BEAM RADIATION THERAPY, THE PATIENT DOES NOT BECOME RADIOACTIVE. AND THE
    RADIATION REMAINS IN THE TREATMENT ROOM.
  • HOWEVER, INTERNAL RADIATION THERAPY CAUSES THE PATIENT TO GIVE OFF RADIATION. AS A RESULT,
    VISITORS SHOULD FOLLOW THESE SAFETY MEASURES:
  • DO NOT VISIT THE PATIENT IF YOU ARE PREGNANT OR YOUNGER THAN 18.
  • STAY AT LEAST 6 FEET FROM THE PATIENT’S BED.
  • LIMIT YOUR STAY TO 30 MINUTES OR LESS EACH DAY.
  • PERMANENT IMPLANTS REMAIN RADIOACTIVE AFTER THE PATIENT LEAVES THE HOSPITAL. BECAUSE OF THIS,
    FOR 2 MONTHS, THE PATIENT SHOULD NOT HAVE CLOSE OR MORE THAN 5 MINUTES OF CONTACT WITH
    CHILDREN OR PREGNANT WOMEN.
  • SIMILARLY, PEOPLE WHO HAVE HAD SYSTEMIC RADIATION THERAPY SHOULD USE SAFETY PRECAUTIONS. FOR
    THE FIRST FEW DAYS AFTER TREATMENT, TAKE THESE SAFETY MEASURES:
  • WASH YOUR HANDS THOROUGHLY AFTER USING THE TOILET.
  • USE SEPARATE UTENSILS AND TOWELS.
  • DRINK PLENTY OF FLUIDS TO FLUSH THE REMAINING RADIOACTIVE MATERIAL FROM THE BODY.
  • AVOID SEXUAL CONTACT.
  • TRY TO AVOID CONTACT WITH INFANTS, CHILDREN
28
Q

CYTOTOXIC SYSTEMIC THERAPY

A
  • TREATMENT OF CANCER WITH CHEMICAL AGENTS
  • USED TO CURE AND INCREASE SURVIVAL TIME
  • ADJUVANT THERAPY = CHEMOTHERAPY + SURGERY OR
    RADIATION
  • CYTOTOXIC EFFECTS EXERTED ON HEALTHY CELLS AND
    CANCER CELLS
29
Q

Drug treatment issues

A
  • DOSAGE
  • SCHEDULING
  • ADMINISTRATION
  • EXTRAVASATION
  • VESICANTS
  • VESICANT VS IRRITANT - NOT THE SAME
30
Q

A
  • CAUSE BLISTERING AND TISSUE DAMAGE WHEN LEAKAGE OUTSIDE THE VEIN
  • CAN BE SEVERE LEADING TO NECROSIS
31
Q

Vesicant intervention

A
  • INTERVENTIONS – SOME HAVE ANTIDOTES (FOR CISPLATIN)
  • D/C IMMEDIATELY, REMOVE FLUID FROM VEIN, APPLY COLD OR WARM DEPENDING ON DRUG AND MD ORDER, REMOVE PRESSURE, ELEVATE LIMB, MARK/CIRCLE AREA WITH PEN TO MONITOR IF GETTING LARGER
  • PREVENTION IS A VASCULAR ACCESS DEVICE (PORT
32

Prevention

34

    APPLY COLD OR WARM DEPENDING ON DRUG AND MD
    ORDER, REMOVE PRESSURE, ELEVATE LIMB,
    MARK/CIRCLE AREA WITH PEN TO MONITOR IF GETTING
    LARGER
  • ASSESS FOR INFECTION OR PROGRESSION
  • PREVENTION IS A VASCULAR ACCESS DEVICE (PORT)
35
Q

Extravasation

A

The leakage of blood, lymph, or other fluid, such as an anticancer drug, from a blood vessel or tube into the tissue around it. It is also used to describe the movement of cells out of a blood vessel into tissue during inflammation or metastasis (the spread of cancer).
