Predictors and trajectories of fear of cancer recurrence in Chinese breast cancer patients.

Objective: Fear of cancer recurrence (FCR) is one of the most common and aversive psychological phenomena among cancer patients. This study explored the trajectories of FCR over the 18 months following discharge, and evaluated the associations between baseline demographic and clinical variables and FCR trajectories among Chinese women treated for breast cancer.

Methods: This is a longitudinal prospective study. All participants were asked to completed a battery of questionnaires (FCR-7, PHQ-9, GAD-7 and MPQ-VAS) at baseline, 6, 12, and 18 months after discharge. Generalized linear mixed model and group-based trajectory analyses were conducted.

Results: Three hundred women with breast cancer were recruited. Latent class growth modeling analysis showed that three-group trajectory solution was the best fitting (i.e., 'intermediate level-stable group' (63.3%), 'low level-increasing group' (18.3%), and 'high level-decreasing group' (18.3%). Patients reported significant higher FCR at baseline assessment compared to other time points. Significant positive associations were found between anxiety, depression and FCR. Patients who had no baseline depression (estimate = -2.14, 95% CI: -2.78-(-1.51), P < 0.001) or anxiety (estimate = -2.77, 95% CI: -3.44-(-2.10), P < 0.001) tended to report significant lower FCRs over time. Women with none/mild life stress exhibited significant lower FCRs than those with moderate/high life stress, and participants with a family history of cancer or pessimism reported higher FCRs.

Conclusion: >60% of the breast cancer women showed intermediate level-stable FCRs over the 18 months after discharge. Baseline anxiety, depression, life stress, family cancer history and pessimism predicts higher FCR levels. Clinical teams responsible for continuing patient care following treatment should develop clearer strategies for management of FCR.
