ASSESSMENT OF RESPONSE
As indicated clinically. Patients should undergo formal objective response
assessment no later than every three cycles.
REVIEW BY CLINICIAN
Patients are to be reviewed by their clinician or their deputy at least once every six
weeks.
NURSE / PHARMACIST LED REVIEW
Prior to each Dose.
ADMINISTRATION NOTES
Patients must be made aware of the risk of delayed diarrhoea occurring 24 hours after
the administration of Irinotecan and at any time before the next cycle. This means
supplying information sheets to the patient and if appropriate to their GP.
Early onset diarrhoea (within the first 24 hours) can be a result of acute
cholinergic syndrome and may occur in 9% of patients. Symptoms are short
lasting and respond within minutes to administration of atropine (0.25-1mg
subcutaneously).
Delayed diarrhoea must be treated immediately with high dose Loperamide (4mg after
first loose stool and 2mgs every 2 hours, to a maximum of 16 (2mg) tablets in 24
hours. Hospitalise if condition not resolved in 48 hours.
For diarrhoea lasting greater than 24 hours add ciprofloxacin 250mg BD. Note
many units give patient a supply of loperamide and ciprofloxacin at the start of
treatment.
Due to the greater frequency of decreased biological functions, in particular
hepatic function, in elderly patients, dose selection with irinotecan should be
cautious in this population. Refer to oncologist for age >70 and performance
status >=2.
