You notice the patient’s liver function tests are deranged:
Bilirubin 7 µmol/L
Alanine aminotransferase (ALT) 73 U/L
Alkaline phosphatase (ALP) 400 U/L
Albumin 30 g/L
You are concerned the patient may now have disease in his liver. You decide to proceed with chemotherapy. Five days into treatment, he becomes confused and agitated, requiring sedation.
What would you do next?
