Several studies have highlighted the need for the provision of extra support for parenting and for the children of families with parental cancer, with particular emphasis on the need to protect the psychosocial wellbeing of these children. However despite this, child-centred work still rarely forms part of clinical practice in adult health-care settings. The aims of the present work were: 1) to calculate a population-based estimate for the number of Finnish children affected by parental cancer, 2) to investigate whether these children had used specialised psychiatric services to a greater extent than their peers, 3) to conduct a systematic review of the scientific literature regarding the current state of structured interventions directly targeted at children with parental cancer, 4) to outline the clinicians' experiences of the use of structured child centred interventions in long-term clinical practice, and 5) to assess whether the "Let's Talk about Children" (LT) and "Family Talk Intervention" (FTI) approaches have any impact on the psychiatric symptom profile of seriously somatically ill parents and their spouses. It was found that every 15th child (6.6% of the children) had a mother or father who was treated for cancer during the years 1987 to 2008. Cases of parental cancer increased these children's use of specialised psychiatric services significantly by comparison with their peers. A systematic review revealed that the existing number of structured child-centred interventions was small and their methodological content was highly heterogeneous. Clinicians' long-term experiences of the use of structured child-centred interventions in everyday clinical practice highlighted: the flexible choice of interventions, the importance of taking the children's needs into account, inter-team collaboration and the need to regard death as an essential topic when working with families with parental cancer. A significant improvement in the parent's psychological symptoms was observed four months after the completion of the structured intervention. It can be concluded that children affected by parental cancer comprise a substantial part of the general population. Both the increased use of specialised psychiatric services by the children and the positive effect of interventions on the parents justify the pursuance of research-based child-centred work.
