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.
