3
Q
Why are haematopoietic tumours so chemosensitive?
A
Haematopoietic tumours are so chemosensitive due to the high rate of cell division seen with this neoplasia
4
Q
Why are sarcomas and carcinomas so chemoresistant?
A
Sarcomas and carcinomas are chemoresistant due to their low rate of cell division
5
Q
What is conventional chemotherapy?
A
Conventional chemotherapy is the use of cytotoxic drugs which have a non-specific effect on all rapidly dividing cells in the body
6
Q
What is the maximum tolerated dose (MTD)?
A
The maximum tolerated dose (MTD) is the maximum dose of conventional chemotherapy that can be administered without causing severe toxicity or unacceptable side effects
7
Q
In which phase of the cell cycle are cells resistant to chemotherapy?
A
G0 phase of the cell cycle
8
Q
Which chemotherapy drug classification targets the M phase of the cell cycle?
A
Vinca alkaloids
9
Q
What is the mechanism of action of the vinca alkaloids?
A
Vinca alkaloids inhibit the mitotic spindle resulting in the prevention of the chromosomes being pulled apart during metaphase, resulting in metaphase arrest and cell death
10
Q

11
Q
Which specific side affects are associated with vinca alkaloids?

13
Q
What is the mechanism of action of the antimetabolites?
A
Antimetabolites intefere with DNA replication and protein synthesis through mimicking essential molecules such as pyrines and pyramidines, resulting in the antimetabolites becoming incorporated into the genetic material, disrupting DNA replication and protein synthesis, resulting in cell death
14

17
Q
What is the mechanism of action for alkylating agents?
A

18
Q

21
Q
How does cyclophosphamide cause haemorrhagic cystitis?
A
When cyclophosphamide is metabolised by the liver, one of the metabolites produced is acrolein. When acrolein comes into contact with the bladder wall, this can cause inflammation and sterile haemorrhagic cystitis
22
Q
What is the consequence of untreated haemorrhagic cystitis secondary to cyclophosphamide administration?
A
Chronic fibrosis of the bladder wall

86
What is acute tumour lysis syndrome?
Acute tumour lysis syndrome is the effect of the acute lysis of neoplastic cells in the first week of chemotherapy where the neoplastic cell burden is at it's highest.

How do you treat acute lymphoid (lymphoblastic) leukaemia?
Acute lymphoid (lymphoblastic) leukaemia is very similar to high grade lymphoma and thus you can use the same chemotherapy protocols as used for lymphoma, such as COP and CHOP. However be aware the prognosis is poor for acute lymphoid leukaemia
95
How do you treat chronic lymphoid (lymphocytic) leukaemia?
In mild cases, chronic lymphoid (lymphocytic) leukaemia does not require treatment. However, in cases that do require treatment, chlorambucil and prednisolone are used

Chemotherapy drugs are dosed based on body surface area
118
What should you be aware of when dosing chemotherapy drugs for smaller patients *(below 10kg)*?
When dosing chemotherapy drugs for smaller patients *(less than 10kg)*, be aware that dosing by based on body surface area won't be as accurate so you may have to underdose or dose based on mg/kg to be safe
119
How do you calculate chemotherapy drug doses?
1. Convert the patient's body weight in kg to m^2
2. Multiply the patient's body surface area by the drug dose in mg/m^2 to get the mg of drug required

132
How can you prepare cytotoxic drugs without a closed system?
1. Use a quiet, well ventilated room with a tray and an absorbent liner
2. Spike the drug vial with a needle whilst the vial is upright
3. Invert the bottle, wrap a swab around the vial and withdraw the drug
4. Re-invert the vial to an upright position
5. Wrap the swab around whilst withdrawing the needle to collect any aerosols
133
What can be done to minimise the risk of exposure when administering cytotoxic drugs?
Good patient restraints *(may require sedation)*

134
What are the benefits of using intravenous catheters when administering cytotoxic drugs?
Prevents perivascular reactions
Allows for thorough saline flushing
Can keep the system closed when using a T-connector
135
What is the 'first stick' rule?
It is important not to administer cytotoxic drugs via an intravenous catheter if it wasn’t placed on the first attempt as there is an increased risk of extravasation of the drug and perivascular reactions
136
What should you do if there is cytotoxic drug extravasation?
1. Stop the injection
2. Suck back as much of the drug as possible
3. Cold compress, except for vinca alkaloids where you should use a warm compress
4. Discuss this complication with the owners
5. Wound management for perivascular reactions, may require surgical debridement and skin grafts
137
What are the benefits of using closed adminsitration systems for cytotoxic drugs?
Closed (needle-less) systems facilitate safe administration and minimise the release of droplets into the environment, thus reducing staff exposure
138
How do you administer an IV bolus of cytotoxic drug without a closed administration system?
1. Check the patency of the IV catheter by first flushing with saline
2. Carefully insert the needle into the injection port
3. Cover with a swab and inject the cytotoxic drug
4. Wrap the swab around the needle when removing it to collect any droplets
5. Flush the IV catheter with copious amounts of saline before removing the catheter
139
How do you administer subcutaneous or intramuscular injections of cytotoxic drugs without a closed administration system?
1. Use a luer lock syringe to attach to the needle
2. After inserting the needle into the patient, place an alcohol soaked swab over the site before injecting the cytotoxic drug
3. Keep the swab over the area when removing the needle
140
What are the rules for administering oral cytotoxic drugs?
Always wear gloves
Never split the tablets
Never crush the tablets
Always give the tablets whole
141
How do you administer oral cytotoxic drugs?
Whilst wearing gloves, administer the tablets with a small amount of food to allow for easier administration, and ensure the patient has swallowed to drug by squirting water into their mouth with a syringe
142
What is important to include when dispensing oral cytotoxic drugs to clients?
It can be helpful to place 'warning tape' on the cytotoxic drug container as well as send the clients home with plenty of gloves
143
What are the possible routes of administration for cytotoxic drugs in horses?
Intravenous administration
Intralesional administration
Intralesional beads *(beads containing chemotherapy drugs implanted into the lesion)*
144
What is the procedure if there is a cytotoxic drug spillage?
1. A cytotoxic spill kit should be available in case of accidental spills
2. Alert members of staff
3. Wear PPE if not doing so already
4. Contain the spill using the spill kit
5. Put any contaminated items into polythene bags
6. Wash surfaces with copius water but make sure to wear a full respiratory mask in case of aerosols
145
Where should cytotoxic waste be disposed of?
Cytotoxic waste should be disposed in cytotoxic waste bins. The contents of these will be incinerated
146
Which organ metabolises chemotherapy drugs?
Liver
147
Where are chemotherapy drugs excreted?
Urine
Faeces
Saliva
148
How long should you barrier against patients undergoing chemotherapy to prevent exposure to cytotoxic drugs?
Recent research suggests that the excretion time is approximately 7 days so you should barrier against these patients for up to 7 days post chemotherapy administration to prevent exposure to cytotoxic drugs
149
Which aftercare precautions should be taken within the clinic to prevent exposure to cytotoxic drugs?
- Have properly trained staff
- Wear PPE when handling the patient
- Warning sign on the kennel door
- All excreta and kennel liners need to be disposed of as cytotoxic waste

150
Which aftercare precautions should be taken at home to prevent exposure of clients to cytotoxic drugs?
- Provide clients with an information sheet and discuss through it at discharge
- Minimise contact between the pet and young children, pregnant women, immunosuppressed individuals
- Discourage pets from sleeping in the owners beds and wash pet bedding regularly
- Good hygiene
