How does the chemo dose in a curative vs palliative patient? Why are the regimes different?
In a curative patient you would have: lower dose chemo but give it more times. This is supposed to reduce SE If a palliative patient: give it at a higher dose and a one off
30
What are 5 SE of Radiotherapy?
Nausea and Vomiting Fatigue Anorexia Oesphagitis
31
What period of time post radiotherapy are SE the worse?

33
What are two ways to scale a patient’s performance status?
ECOG WHO’s performance status
34
What are 3 complications of chemotherapy?
1. Alopecia: this is reduced by sitting them underneath a cold cap 2. Nausea and Vomiting: give anti-emetics like ondansetron 3. Anaphylaxisis: prevented by taking steroids the day before 4. Extra vascularisation: this is when you give SC injections and it causes necrosis of large patches of skin. Prevented by using smaller ‘yellow’ needles.
35
How do we prevent anaphylactic reactions in patients who are given chemotherapy?
You start them on steroids the day before
36
What complication is related to the use of 5- FU creams?
Coronary Artery Spasm

Myeloma Bone mets
39
What would the zone of transition look like in a patient with A. Benign bone disease B. Malignant bone disease
Benign you would have a narrow zone of transition Malignant you would have a wide zone of transition
40
What does a periosteal reaction signify?
A bone reaction
41
What is codman’s triangle sign seen on x-rays? What cancer is it associated with?

45
What are 4 cancer types that are associated with major haemorrhage?
1. Head Cancer 2. Neck Cancer 3. Bowel Cancer 4. Lung Cancer
46
If you had a palliative patient with a haemorrhage how would you respond?
1. Give midazolam | 2. Use dark coloured towels
47
Describe what the following abbreviations mean: A. Planning target volume (PTV) B. Clinical Target Volume (CTV) C. Gross Target Volume (GTV)
A. Planning target volume (PTV): degree of movement B. Clinical Target Volume (CTV): area of micro spread C. Gross Target Volume (GTV): size on CT
