An integrative literature review was undertaken to explore existential concerns among patients with cancer with respect to components, related concepts and targets of interventions. ⋯ Interventions targeted and evaluated concepts related to existential concerns found in the descriptive studies. Gaps in research on existential concerns in patients with cancer include the need to clarify the concept; how patients' existential well-being may best be supported by health-care professionals in everyday practice; effects of existential interventions on physical symptoms; and stability of results of interventions.
