incidence of cancer
A
- most commonly diagnosed: lung, breast/prostate, colorectal
- estimated 1 in 3 people will have cancer in their lifetime
9
Q
what are some modifiable risk factors for cancer
A
- tobacco use
- environment
- diet
- physical activity
- sexually transmitted disease/infections
- alcohol/drug use
- occupation/military work
- ionizing radiaition
10
Q
what are non-modifiable risk factors
A
- age
- ethnicity
- family history and genetics
11
Q
What is paraneoplastic syndrome
A
- cancer cells take on new roles of other cells
- resemble primary disorders of endocrine, metabolic, hematologic, cutaneous, neurological, neuromuscular
- unknown cause
12
Q
what are potential causes of paraneoplastic syndrome
A
- inflammation due to tumor growth
- autoantibodies
13
Q
examples of paraneoplastic syndrome
A
- cushings syndrome: small cell lung cancer
- lambert-eaton syndrome: SCLC
- raynaud’s plasma cell
- polymyalgia-lymphoma
- necrotizing vasculitis-lymphoma
- palmar fasciitis- ovarian cancer
- ALS, myasthenia gravis
- polymyositis, dermatomyositis
14
Q
What is stiff-person syndrome
A
- rare paraneoplastic syndrome
- precursor to lung or breast cancer
- can also be genetic or autoimmune disorder
15
Q
A
16
Q
symptoms of
stiff person syndrome
A
- sudden painful spasms in hips or back
- can progress to abdomen, arms, face
- affects walking, adls, mental health
17
Q
Other examples of paraneoplasmic syndrome: non-specific
A
- anorexia (Related to TNF: cachexin which supresses hunger)
- fatigue
- fever (related to pyrogen production)
18
Q
What is cancer related fatigue
A
- persistent tiredness or exhaustion
- may no be related to course of disease
- common ith chemotherapy, radiation, biological modifiers, bone marrow transplant
- may be related to higher levels of inflammatory markers, TNF
- lower cortisol levels
- anemia
19
Q
Oncologic pain
A
- signs of cancner or related to cancer treatment
20
Q
Biologic causes of oncologic pain
A
- bone destruction
- visceral or circulatory obstruction
- nerve compression
- tissue or skin distension
- inflammation, infection, necrosis
21
Q
Pain management - PT
A
- functional activities
- exercise
- relation
- massage/manual therapy
- E-stim
- ice
- biofeedback
- complementary/alternative interventions
22
Q
Chemo-induced peripheral neuropathy PT exercises
A
- ther ex during chemo reduces risk
- aerobic exercise
- HIIT
23
Q
Meds for chemo-induced peripheral neuropathy
A
- miragabalin: gabapentinoid, long half-life, binds to Ca+ channels
- PEA: endogenous bioactive lipid, modulates inflammation
- clonidine: used for ADD, reduces allodynia
24
Q
Breast-cancer related lymphedema
prevention and intervention
A
- monitoring
- compression garments: KT tape
- MLD, CDT massage
- resistance and aerobic exercise
- low level laser therapy
- acupuncture, yoga
25
Multiple myeloma
| PT interventions to reduce..
- fatigue
- muscule wasting
- sleep disruption
- improve QOL
26
multiple myeloma
| considerations for exercise and mobilization
- hemoglobin - bone marrow cancer could affect
- platelets
- neutropenia: common side effects of chemo causing severe immunocompromised
- bony lesions
27
Hospice
end of life or near end of life
within 6 months
28
palliative care
serious condition that may require hospice
29
What does hospice and palliative care both focus on
- focuse on management of pain and other symptoms
- can occur with hospice
- can occur with rehab
30
What are the goals of hospice/palliative care
- maximize Quality of life
- prevent secondary conditions
- rehab in reverse (goasl for maintaince/training caregiver)
- hospice services are bundled: patient gets personnel as needed, PT for pain/mobility, interdisciplinary team
31
Pain management - medical for hospice/palliative care
- as needed
- around the clock
- patient controlled analgesia
- may need a pain pump
32
prevention of cancer: primary
- risk factor assessment
- early detection
- follow the ten commandments
33
Tertiary prevention of cancer
- radiation, chemo
- complmentary and alternative medicine
- surgery
- biotherapy, antiangiogenic therapy
34
35
What is biotherapy
- immunotherapy, immune based therapy
- uses biological response modifiers (interferons, IL-2 cytokines)
- bone marrow or stem cell transplants
- monoclonal antibiodies
36
What are monoclonal antibodies
- rituximab (rituxan): lymphoma, leukemia
- trastuzumab (herceptin): breast cancer, stomach cancer
- alemtuzumab (campath-1H): chronic lymphocytic leurkemia
- cetuximab (erbitux): bowel cancer
- Bevacizumab (Avastin)
| mab=monoclonal antibodies
37
What is antiangiogenic therapy
- stops growth of blood vessels
- uses antiangiogenesis factors: endostatin, angiostatin, calpastatin
- cuts of blood supply to tumor
- stops pathologic angiogenesis
- may need to mutliple inhibitors due to redundancy
| not as effective if cancer has spread
38
what is hormonal therapy
- used if cancer is affected by a specific hormone
- tamoxifen: anti-estrogen
- leurprolide: inhibits testosterone
- goserelin: inhibits gonagotropins in pituitary => decreases testosterone
