The evolution of fear of cancer recurrence during the cancer care trajectory and its relationship with cancer characteristics.

OBJECTIVE: This population-based longitudinal study assessed the prevalence, incidence and evolution of fear of cancer recurrence (FCR) and its relationship with some cancer characteristics in a large sample of patients with mixed cancer sites over an 18-month period.
METHODS: A total of 962 patients scheduled to undergo surgery for cancer completed the severity subscale of the Fear of Cancer Recurrence Inventory at the peri-operative period and 2, 6, 10, 14, and 18 months later.
RESULTS: Results indicated that FCR levels were highest at baseline, significantly decreased at the 2-month evaluation and then remained stable throughout the remainder of the study. Between 44.0% and 56.1% of the patients reported a clinical level of FCR during the study, with the highest proportion found at baseline. A relationship was obtained between greater FCR and some indices of poorer prognosis (i.e., diagnosis of head and neck cancer, more advanced cancer, cancer recurrence), as well as with the administration of adjuvant treatment, particularly chemotherapy. Patients with clinical FCR at baseline continued to display clinical levels at all subsequent time points. The incidence rate of clinical levels of FCR was 51.7% overall.
CONCLUSION: FCR is a highly prevalent and persistent condition. More efforts should be devoted to developing effective treatments for patients with clinical levels of FCR. Early interventions appear particularly relevant in order to prevent the problem from becoming chronic, although patients' acceptability and the efficacy of this approach remain to be demonstrated.
