Diarrhoea in adult cancer patients: ESMO Clinical Practice Guidelines

Diarrhoea is defined as the frequent passage of loose stools with urgency (or more frequent passage than is normal for the individual). Objectively defined, it is the passage of more than three unformed stools in 24 hours [1]. Often the patient's definition of diarrhoea varies and needs to be clarified by medical staff, through an adequate assessment.
