18
Q

How can where the cancer is be identified

A

Through examination

Radiology/imaging (e.g. CT, MRI, USS, PET etc.)

19
Q

How can the type of cancer be identified

A

Through pathology and cytology

20
Q

What does surgery require

A

Anatomical clearance

21
Q

What does radiotherapy require

A

Anatomical coverage

22
Q

What are the benefits of radiotherapy

A

Can treat inoperable lesions
Can make surgery become possible
Can maintain function and/or appearance

23
Q

What are the 5 R’s of radiobiology

A 
Radiosensitivity
Repair
Re-population
Re-oxygenation
Re-assortment
24
Q

Describe the features of radiotherapy

A

About 40% of cancers are cured by radiotherapy (e,g, head and neck, cervix, uterus, skin and lymphoma)
Can be combined with chemotherapy (e.g. anal cancer, rectal cancer, oesophageal cancer)
Important role in palliation (e.g. pain, bleeding, swollen limbs)

25
Q

State an advantage and disadvantage of systemic treatments

A

Beneficial for widespread disease

Can result in widespread toxicity

26
Q

What are the indications for the use of cytotoxic drugs

A

‘Curative’
Palliative
Adjuvant
‘Neoadjuvant’

27
Q

What are designer therapies

A

‘Specific’ therapies based on molecular science

28
Q

What kind of immune therapies are there

A

Non-specific/innate

Specific

29
Q

What kind of therapy uses monoclonal antibodies

A

Rituximab

30
Q

What does the programmed cell death pathway type of immune therapy do

A

Uses immune system to attack ‘foreign’ cancer cells

31
Q

What does the chimeric antigen receptor (CAR) T-cells type of immune therapy do

A

Artificial T-cell receptors using retroviral vectors to give a specific cell killing function directed against cancer cells

32
Q

What can be used as a checkpoint blockade

A

PD-1

PDL-1 antagonists

33
Q

Where are checkpoint blockades currently in use

A

Melanoma

Lung cancer

34
Q

What does the success of checkpoint blockades depend on
