Q

persistent effects

A

Began during chemotherapy, often worsen &
don’t necessarily go away

21
Q

late effects

A

develop montsh to years after tx

cardiomyopathies
arrythmias
lung parenchyma change resulting from radiation –> fibrosis

22
Q

persistent effect: cancer related fatigue

A
  • Most distressing
    symptom associated
    with cancer & its
    treatment
  • Experienced by 70-
    100%
  • Can last months to
    years
23
Q

cancer related fatigue

A

Persistent subjective sense of exhaustion
related to cancer or cancer treatment that
interferes with usual function

Not relieved by rest or sleep
 Does not correspond to level of exertion
 More severe and distressing
 Disproportionate level of fatigue

24
Q

therapy for cancer related fatigue - exercise

A

~25% reduction in fatigue in cancer
survivors randomized to the exercise group

25
Q

direct mechanism of hoe exercise improves fatigue

A

Muscle strength &
endurance
 Cardiopulmonary fitness
 Dampened
Inflammatory response
 Improved insulin
function

26
Q

indirect mechanism of how exercise improves fatigue

A

Diminished anxiety and
depression
 Improved sleep
 Improved cognition

27
Q

how exercise improves survival

A

Breast Cancer: 30% lower risk of morality
 Prostate Cancer: 30% lower risk
 Colo-rectal Cancer: 50% lower risk
 Brain Tumors: 36% lower risk

28
Q

why does exercise reduce cancer recurrance and mrotality

A

Decreased circulating hormone levels
 Decreased inflammation
 Improved insulin sensitivity
 Promotes weight loss/controls weight gain
 Helps maintain weight loss

29
Q

PA among cancer survivors

A

76.8% without cancer DID NOT meet
recommendations of 150 min/week
 95.5% cancer survivors DID NOT meet
recommendations

30
Q

ACSM rountable guidelines on exercise - breast cancer

A

Aerobic fitness is improved (2010&2019)
 Muscular Strength improved (2010&2019)
 Physical Function improved post therapy (2010&2019)
 Exercise is safe (2010&2019)
 Anxiety (2019)
 Depression (2019)
 Fatigue (2019)
 Lymphedema (2019)
Evidence Category A: Breast Cancer

category B
Fatigue levels decline (2010)
 Quality of life improves (2010)
 Depression & Anxiety declines (2010)
 Body size & composition improves (2010)
 Bone Health (2019)
 Sleep (2019

31
Q

gaps in the literature related to exercise

A

Falls
 Cardiotoxicity
 Peripheral Neuropathy
 Cognitive Function
 Nausea
 Pain
 Sexual Function
 Treatment Tolerance

32
Q

what is exercise based oncology rehab

A

Use of physical therapy and exercise modalities to
improve or maintain function, ameliorate or prevent
side effects of cancer/cancer therapy, and improve
fitness and strengt

33
Q

increased emphasis on PT

A

Focus on specific impairments Encouraging exercise
without assessing and treating physical impairments
can cause problems
 Skills to deal with many cancer related side effects:
ROM, lymphedema, balance, strength, fatigue
 Training in exercise assessments and interventions
 PT evaluation  insurance reimbursement

34
Q

patient with cancer are different

A

Limited prognosis
Extensive medical co-morbidity
High degree of pain
Psychosocial distress
Dynamic disease process
Side effects of antineoplastic therapy
Unique goals of care

35
Q

Exercise post therapy associated w/ reduced:

A

 Fatigue
 Shortness of breath
 Pain
 Depression

36
Q

exercise 6 months latter associated with reduced

A

sleep disturbance
memory problems
fatigue

37
Q

physiological benefits of exercise during tx

A

Increased lean tissue mass
Increased VO2 max
Decreased resting heart rate
Improved training distance
Increased upper and lower body strength
Improved flexibility
Higher physical functioning scores

38
Q

benefits of exercise during tx: qol

A

Decreased fatigue
Decreased nausea
Improved sleep patterns
Lower pain perception
Less emotional and psychological distress
Lower depression and anxiety

39
Q

treating cancer related fatigue

A

Physical Activity
* Walking program throughout treatment tends to decrease CRF
Mock 2007
* Aerobic training
*  blood flow
*  hemoglobin
* Strength training
*  muscle enzymes
* Enlarges muscle fibers
* Too much of a good thing?
* Gentle moderate exercise decreased inflammation
* Overly aggressive exercise increases inflammation

40
Q

neoplasm

A

“new growth”- not necessarily cancerben

41
Q

benign

A

innocuous, harmless to host unless large enough to compress or obstruct surrounding tissue

42
Q

malignant

A

Aggressive, if left untreated will invade other organs and result in death

43
Q

remission

A

Operationally defined according to diagnosis,
usually associated with being free of
symptoms

44
Q

cure

A

No evidence of disease and same life
expectancy as person who was never
diagnosed

45
Q

medical tx

A

Multimodal!
Strategies include:
* Surgery
* Chemotherapy
* Radiation Therapy
* Immunotherapy
* Hormonal Therapy

46
Q

persistent effects

A

began during chemotherapy, often worsen & don’t necessary go away

47
Q

late effects

A

develop months to years after treatment

48
Q

thrombocytopenia

A

Low Platelet Counts
* Bruising
* Malaise and fatigue
* Nosebleeds
* Bleeding gums
* Blood filled bullae in mucous membranes
* Continuous bleeding

49
Q

neutropenia

A

low levels of neutrophils’

Immune system compromise from cancer therapies increase the risk for infection
ANC (absolute neutrophil count)
* the precursors of the WBC’s
* found in the bone marrow
* A more accurate measure of infection risk

50
Q

what we do prevention

A

Hand Washing!
Encourage good pulmonary toileting
Encourage hygiene
Encourage ambulation
Mask and gown
Food restrictions?
Live plant restrictions?
Kitty litter?

51
Q

hemoglobin values

A

10-12: - Aerobic Exercise as tolerated
8-10: - Ambulation and ADL’s as tolerated
- Monitor for lightheadedness, chest pain,
SOB, weakness
<8: - Limited activity
- Patients will become more
symptomatic with activity and have lower
tolerance for exercise
