Check full blood count before starting treatment, once weekly for the first four weeks, then at least every 3 months throughout treatment. Check:

• Haemoglobin
• Total white cell count
• Neutrophil count
• Platelet count
• also check liver function tests

Patients should immediately have a full blood count if they develop any symptoms suggestive of marrow depression.
