- Nausea
- Diarrhoea
- Mucositis
- Fatigue
- Lymphoedema
- Dysuria / radiation cystitis
- Sterility

Long term side effects:
Occurs months to years after a course of radiation (from excessive extracellular matrix, deposition of collagen and fibrinogenesis)
- Radiation-induced fibrosis
- Atrophy
- Neural or vascular damage
- A range of endocrine effects (e.g. diabetes, hypothyroidism)

*Small risk of a secondary malignancy, due to radiation-associated DNA damage

Q

Outline in very basic terms how radiotherapy works

A

Radiotherapy uses high energy, ionising radiation to eliminate cancer cells (ionising means charged particles, which then deposit energy into the cells of the tissues they pass through)

Local technique - aim is to maximise the dose of radiation delivered to cancer cells whilst minimising exposure to healthy cells

Causes cell death in one of two ways:
1) Triggering apoptosis by causing significant DNA damage
2) Preventing proliferation, by causing single and double-stranded breaks in DNA (known as mitotic cell death)

Q

State the 2 most common methods of delivering radiotherapy

A

2 primary methods of delivering radiation to tumours:

1) External beam radiation:
- Delivered from outside the body by aiming high-energy rays

2) Internal radiation (brachytherapy):
- Uses radioactive material in catheters or seeds
- Delivers high doses of radiation from inside the body directly into the tumour site

+ systemic treatment, with radioactive substance (injected/swallowed)

69
Q

Outline the meaning of radical / curative in terms of cancer treatment

A

Radical therapy aims to reduce the size of the tumour shrink and control the growth of the tumour, with the intent of curing the cancer and prolonging life (intended to induce remission and prevent recurrence)

Vs palliative, which aims to control the cancer and sometimes cancer, but without curative intent

70
Q

Outline the meaning of life-extending treatment in terms of cancer treatment

A

Treatment offered with the aim of extending life for a meaningful period of time (sometimes with intent to be present at a life event e.g. birth of a grandchild), but without being curative

Different to palliative as it’s not aimed at improving palliative symptoms or QOL specifically

71
Q

Outline the meaning of palliative in terms of cancer treatment

A

Intent of treatment is not to cure, expectation is that treatment will improve patient’s symptoms and QOL (sometimes at the expense of other outcomes e.g. survival) or prevent development of cancer-related symptoms

It’s an approach that takes into account the person as a whole

72
Q

Outline the meaning of neo-adjuvant in terms of cancer treatment and some examples

A

Treatment given to shrink the size/burden of a tumour prior to surgery (or other main treatment), to improve the success rate of the main treatment

Examples:
- Chemotherapy
- Radiotherapy
- Hormone therapy

73
Q

Outline the meaning of adjuvant in terms of cancer treatment

A

Treatment given after the main treatment, to kill any residual cancer cells and reduce the risk of the cancer recurring

74
Q

Outline the meaning of maintenance in terms of cancer treatment

A

Ongoing treatment after cancer has responded to initial treatment, with the intention of reducing the cancer coming back after initial therapy

Longer term therapy that can last for years, to help remission last as long as possible

33%

80
Q

Worldwide, how many new cases of cancer are there each year?

A

18 million new cases worldwide

81
Q

Worldwide, how many death are caused by cancer each year?

A

10 million deaths from cancer worldwide each year

82
Q

State the purpose of clinical trials in cancer care management

A

Trials test if a new treatment is more effective than the current treatment
Also provides information on safety profile + side effects of new treatment

83
Q

Briefly explain the phases of Cancer clinical trials

A

Pre-clinical: tested microscopically and then on animals

Phase 0 + 1 (small numbers + lots of cancer types):
- What dose of a drug is safe?
- Whether positive effect on cancer?
- Side effects?

Phase 2 (larger numbers + 1 cancer type):
- Which cancers can it be used for?
- More detail about side effects + how to manage side effects

Phase 3 (larger numbers + 1 cancer type):
- It new treatment as good as the standard treatment?
- Fewer side effects?
If a phase 3 trial shows a cancer drug is safe and effective = company can apply for a drug license

Phase 4 (test drugs already licensed):
- Success when used on more people
- Long-term effects
- More about rare side effects + safety

84

Infertility
Stunted growth

86
Q

List medications that should be used for chemo-induced nausea and vomiting

A

- Benzodiazepines e.g. Lorazepam

87
Q

State the 3 main types of sarcoma

A
  1. Osteosarcoma – the most common form of bone cancer
  2. Chondrosarcoma – cancer originating from the cartilage
  3. Ewing sarcoma – a form of bone and soft tissue cancer most often affecting children and young adults
88
Q

List some ways in which sarcomas may present, ways in which they are investigated and how they can be managed

A

Presentation:
- Soft tissue lump (esp. if growing, painful or large)
- Bone swelling
- Persistent bone pain

Investigations:
- X-ray (if bone suspected)
- Ultrasound(if bone soft tissue suspected)
- CT /MRI scans (more detail / metastatic spread)
- Biopsy

Management:
Managed by sarcoma MDTs at specialist sarcoma centres
- Surgery (surgical resection is the preferred treatment)
- Radiotherapy
- Chemotherapy
- Palliative

89
Q

State some risk factors for sarcoma

A
  • Inherited syndromes e.g. familial retinoblastoma, neurofibromatosis type 1
  • Radiotherapy

  • Exposure to viruses (human herpesvirus 8 for Kaposi’s sarcoma)
90
Q

A
  1. Direct
  2. Lymphatic
  3. Haematogenous
  4. Transcoelomic
91
Q

Outline some treatment options for brain metastases

A

Palliative approach = symptom control/comfort e.g. Dexamethasone

Treatment:
- Neurosurgery
- Stereotactic radiosurgery (gamma knife)
- Immunotherapy
- Whole brain radiotherapy (WBRT): extensive disease

92
Q

For the following treatment options for brain metastases, outline when they can be used
- Neurosurgery
- Stereotactic radiosurgery (gamma knife)
- Immunotherapy
- Whole brain radiotherapy (WBRT): extensive disease

A

Neurosurgery:
- Single met or <3 accessible lesions
- Disease otherwise well controlled

Stereotactic radiosurgery (gamma knife):
- Small number of mets
- Overall good performance status
- Disease otherwise well controlled

Immunotherapy:
- Multiple small volume metastases
- Overall good performance status

Whole brain radiotherapy (WBRT):
- Extensive disease

93
Q

List some side effects of steroids

A
  • Difficulty sleeping
  • Increased appetite (weight gain)
  • Hypertension
  • Hyperglycaemia or diabetes
  • Osteoporosis
  • Immunosuppression risk e.g. chickenpox, shingles and measles
  • Cushing’s syndrome
  • Glaucoma / cataracts
  • Changes in mood e.g. anxiety / irritability
94
Q

Outline the difference between targeted therapy and immunotherapy

A

Targeted therapy:
- Work by targeting the differences in cancer cells that help them to grow and survive

Immunotherapy:
- Help the immune system to attack cancer

95
Q

State some side effects of immunotherapy in cancer

A

General inflammation in the body

  • Allergic reaction / anaphylaxis
  • Diarrhoea / abdominal pain
  • Fatigue
  • Flu-like symptoms e.g. fever, muscle aches, headaches
  • Reaction at site of injection e.g. pain, erythema / skin rash
  • Palpitations
  • Sweating
  • Weight changes / appetite changes
  • Polyuria
  • Organ inflammation (more rare)
