Seven-year distress trajectories in uveal melanoma survivors.

OBJECTIVE

Severe or persistent distress is associated with poorer quality of life in cancer survivors. Distress follows distinct trajectories within different population subgroups. Identifying characteristics and causes of trajectories can assist intervention development and targeting. In a 7-year study of uveal melanoma survivors, we aimed to characterize anxiety, depression, and fear of cancer recurrence (FCR) trajectories, and identify whether concerns about symptoms and functional problems over the first 3 years of survivorship predict memberships of high distress trajectories.

METHOD

In a closed cohort study, we used growth mixture modeling (GMM) to identify statistically optimal trajectories over 6-, 12-, 24-, 36-, 48-, 60-, 72-, and 84-month time point posttreatment in 475 patients. We then regressed trajectory memberships onto a 3-year series of measures of concerns about symptoms and functional problems, controlling demographic, clinical, and 6-month anxiety, depression, or FCR indicators.

RESULTS

Anxiety, depression, and FCR were represented by two-class linear GMMs. The majority scored consistently low, but 17.5% showed consistently elevated anxiety, 10.9% consistently elevated depression, and 19.4% consistently elevated FCR. Higher anxiety trajectory membership was predicted by greater concerns about symptoms at 6 and 24 months, higher depression trajectory membership by symptoms at 24 months, and higher FCR trajectory membership by symptoms at 6 and 24 months and functional problems at 12 months.

CONCLUSIONS

Much of the burden of persistent distress in cancer patients falls on a small proportion of survivors. Concerns about symptoms and functional problems are potential risk factors for distress. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
