Late sequelae to cancer treatment of the pelvic organs are common. Gastrointestinal symptoms including chronic diarrhoea, faecal urgency, and faecal incontinence are some of the most disabling with a negative impact on quality of life. By investigating and treating the gastrointestinal symptoms in specialised late adverse effects clinics more than half of the patients can be helped. The treatment is individually tailored depending on the patients' main symptoms and underlying pathophysiology performed in collaboration between gastroenterologists, surgeons, oncologists, dieticians, and specialised nurses, as argued in this review.
