L31/32 Physiotherapy and Cancer Flashcards
What is cancer?
- Cancer is a disease of the cells
- Occurs when abnormal cells grow in an uncontrolled way
- These cells can damage or invade the surrounding tissue –or spread to other parts of the body
Most cancers start in a particular organ –this is called the _____ site
primary
What are the 2 types of tumours?
- Benign tumours (not cancer)
- Malignant tumours (cancer)
What are the 5 different types of cancer?
- Sarcoma
- Carcinoma
- Starts on the skin, organ (eg, bowel , melanoma, ovarian
- Leukaemia
- Lymphoma + myeloma
- CNS tumours
- Begin in brain and spinal cor (glianoma..etc)
What is the staging of cancer?
can classify the spread of cancers (used for solid tumours eg. breast cancer rather than blood cancer)
What is the TNM staging system?
globally recognised standard for classifying the extent of spread of cancer
What are the 3 factors of the TNM staging system?
- T(tumour) –indicates the size and extent of the primary tumour (Tx, TIS, 0-4)
- N(nodes) –indicates whether the lymph nodes are affected (Nx0-3)- How close (eg. axillary nodes —> supra-clavaicular nodes)
- M(metastases) –indicates whether there are distant metastases (0-1)- 1= they do have distant metastases)
_____ is a major cause of ill health in Australia
Cancer
While more cancer cases are being diagnosed, death rates have continued to ____. Survival rates have also _____ Why?
fall; improved
Due to better technology (better scan, understandings) Treatment is improving
What is the estimated most commonly diagnosed cancers (2017) for Females?
What is the estimated most common cause of death from cancers (2017) for females?
What is the estimated most commonly diagnosed cancers (2017) for males?
What is the estimated most common cause of death from cancers (2017) for males?
Whata re the 3 principles of cancer treatment?
- Cure
- Not always possible as they might be diagnosed late
- Control & Prolongation of life
- Stop it worsening/stop it worsening –> can live quite well but need treatment
- Palliation of symptoms- Diagnosed very late
- Causing them pain (eg. reaceive radiation for bony mets)
What are 3 factor principles of cancer treatment?`
- Tumour factors
- Treatment factors
- Individual factors
What are tumour factors of principles of cancer treatment?
- Where is the tumour located ? (location- eg. lung cancer wrapped around superior vena cava)
- How far can it spread
What are treatment factors of principles of cancer treatment?
Effectiveness, cost?
What are individual factors of principles of cancer treatment?
- General health (older patient –> performing invasive surgery –> could be highly dangerous),
- Financial status
- Perceptions of cancer
- Location of living (rural, remote)
- Body image (don’t want to lose a breast, might metatase but they rather)
- Working Active/independent
What are 6 cancer treatment modalities?
- Surgery
- Drug Therapies
- Chemotherapy
- Hormone Therapy
- Targeted Therapy
- Immunotherapy
- Radiation Therapy
- Neoadjuvant
- Adjuvant
- Combination
What is neoadjuvant as cancer treatment?
Get initial use of treatment (chemo, radiadtion) before they operate (surgery)
What is adjuvant as cancer treatment?
Additional treatment of chemo, radiation) after surgery (try to make sure they get all of it during surgery and then use other treatment to make sure they get all of it)
What is combination of neoadjuvant and adjuvant as cancer treatment?
- Common in head and neck (have surgery and chemo/radiation at the same time
- Increase effectiveness
What is surgery for cancer treatment?
Performed by surgeon or surgical oncologist to remove cancer from the body or repair a part of the body affected by cancer
What are 8 reasons for surgery as a cancer treatment?
- Prevention
- Take both breast (in case it affects other side)
- Diagnosis
- Biopsy to confirm
- Staging
- Primary treatment
- Remove tumour (abnormal issue and issue around it)
- Debulking
- Common in brain tumours (eg. cant remove all so try and remove as much as possible)
- Reconstruction
- Use breast from own body parts
- Supporting other treatments
- Palliative
- Drain plural diffusion
What are the 7 side effects of surgery as cancer treatment?
- Pain
- Blood loss
- Swelling + bruising
- Numbness/nerve pain/nerve damage
- Infection
- DVT
- Nausea/vomiting
What is chemotherapy?
- The use of drugs to kill or slow the growth of cancer cells
- Chemotherapy destroys the cells that are dividing rapidly
- Can be a single drug or a combination of several
What are 12 side effects of chemotherapy?
- Fatigue
- Appetite changes, nausea, vomiting
- Constipation
- Skin and nail (Go yellow and fall out) changes
- Hair changes (fall out)
- Mouth sores- Can’t eat
- Thinking and memory changes
- Can’t remember things
- Nerve and muscle effects
- Peripheral neuropathy (eg. Have trouble putting on shoes)
- Fertility
- IVF (will impact ability to have kids)
- Low platelet count
- Bruising and bleeding more easily
- Low red blood cells
- Contributes to fatigue
- Neutropaenia
- Greater risk of infection (can be a medical emergency in cancer patients)
- Cardiac toxicity
- Already in stage A heart failure (more common after having chemo, treatment than having a relapse)
What is radiation therapy?
Ionisation radiation Radiation to kill cancer cells or damage them so they cannot grow or multiply
Radiation therapy is a ______ treatment.
localised
While chemo affects whole body
What are the 4 ways that radiotherapy can be given?
- External radiotherapy
- External –> provides radiation
- Lie on couch
- Machine moves around but wont touch
- No. of beams prescribed for treatment
- Internal radiotherapy
- Brachytherapy
- Implants
- Common in prostate cancer to deliver small doses of radiation
What are 8 side effects of radiation therapy?
- Radiation = localised (depends on body part
- May build up over time- Accumulative (even after treatment)
- Fatigue
- Skin problems- Bad sunburn
- Appetite loss- Often in brain
- Nausea- Often in brain
- Bladder and bowel irritation- Colorectal or prostate
- Hair loss
- Infertility- Pelvic region
- Radiation induced fibrosis- Scarring, poor vasculature –> cosmetic impact –> impacts QoL (restricts movement)
What are the impacts for physiotherapist of radiation therapy?
- Do not apply heat or perform manual techniques over irradiated skin
- Avoid forceful stretching of any irradiated joints/muscles
How does skin type get affected by radiation therapy?
- Darker skin = less problems (compared to paler skin)
- Dull erythema = sun burn affect
- Dry desquamation
- Moist desquamation
What is targeted therapy?
- Focuses on proteins or mutations found in some tumours
- Attack specific targets inside tumours that cause the tumour to grow uncontrollably
- Herceptin
- HER-2 (breast cancer)
- Dabrafenib
- B-RAF (melanoma)
What are the 2 types of Attack specific targets inside tumours that cause the tumour to grow uncontrollably (target therapy)?
- Herceptin (To try attack pathway)–> HER-2 (breast cancer)
- Quite aggressive
- Dabrafenib –> B-RAF (melanoma)
How did immunotherapy works?
- Boost the immune system so it works better against cancer
- Remove barriers to the immune system attacking cancer
What are 3 characteristics of advanced melanoma using immunotherapy?
- Keytruda
- Opdivo
- Yervoy
What is a characteristic of cervical cancer using immunotherapy?
HPV vaccination
How does hormone therapy work?
- Use other hormones bind to receptor rather than estrogen binding
- High levels of estrogen –> increased risk of breast cancer
