Rationale

Nausea and vomiting (N/V) are among the worst symptoms in patients with advanced cancer. The risk of N/V depends on several factors and is in the literature described to vary between 6-68 % in these patients. Despite continuing progress in the treatment of chemotherapy-induced nausea and vomiting during the last 30 years, the incidence and severity of N/V are roughly unchanged in patients with advanced cancer receiving palliative care. Evidence regarding the effect of antiemetic treatment for cancer patients in palliative care is sparse. The most recently published reviews conclude that no guidelines can be established based on the present level of evidence, and that new research is urgently needed.

In summary, the burden of N/V is very significant and N/V can, if untreated, lead to rapid deterioration in this old and fragile group of patients. The evidence base for treatment is minimal. Research in the treatment of N/V in palliative care therefore seems highly warranted, and these studies will have the potential to create important new knowledge.
