RÉSUMÉ

This review describes the family interpersonal dynamics due to the onset, the course and the outcome of cancer as well as a psychological treatment program for the family caregivers. The literature concerning the family environment of cancer patients highlights two issues: the first concerns the change in relationship patterns in the family as well as in the context of care, the second refers to the psychological and/or psychopathological consequences for the caregivers. These clinical features consist of adjustment disorders and post-traumatic syndromes often observed in the caregiver and in the patient's children. The structure itself of family relationships is negatively affected by the disease. Role conflicts, increasing communication deviances, social isolation, disorganized or enmeshed relationships are described. The knowledge of these processes suggests to schedule tailored psychological support programs for the patient's partner and the families. These interventions are aimed at improving the active collaboration between family, patient and medical team as well as at supporting the family during the critical phases of the disease and of cancer treatments. A treatment program, including a counselling module, called "Family Psychoncological Counseling" and a psychotherapeutic module, called "Phasic Family Therapy," is described.
