A qualitative study Abstract:Background: In the last year of life, persons with advanced cancer and their significant others are affected by several transitions. They perform psychological adjustment processes during transformation. This requires strategies for patients and their significant others. Research in German about this theme is missing. Aim: We explored the experiences with illness management during transitions in the last year of life of patients with advanced cancer and their significant others. Method: In this qualitative study, we conducted structured interviews with five dyads, consisting of persons with Karnofsky Index ≥ 60 % and life expectancy of six to twelve months as well as their significant others. To interpret the interviews, we used qualitative content analysis according to Mayring. Results: The main theme "Don't let the world become too small" expresses that limitations diminished the lifeworld and the participants struggled against this process. This is revealed in three categories: "Being shocked by diagnosis -realigning again", "Bearing limitations and loss -finding new ways in daily life", "Living in uncertainty -holding out together".
