TOPLINE:
About one third of adult survivors of childhood cancer experience a clinically significant or high fear that their primary cancer may recur or that they will develop a subsequent malignancy, according to a recent analysis. The study finds that several factors are associated with a higher risk of experiencing a clinically significant fear of recurrence, including being unemployed or having elevated anxiety or depression.
METHODOLOGY:
- Adult survivors of childhood cancer face a high risk of developing subsequent malignant neoplasms — about a sixfold greater risk than in the general population — and studies indicate that these cancer survivors also fear their cancer will recur. However, data on the prevalence of and risk factors associated with clinically significant fear of recurrence in this population remain limited.
- This cross-sectional study included 229 adult survivors of childhood cancer (mean age at study completion, 39.6 years), recruited from the Childhood Cancer Survivor Study, who completed online surveys between October 2018 and April 2019.
- Fear of cancer recurrence was assessed using the 9-item Fear of Cancer Recurrence Inventory–Short Form, which defines recurrence as the possibility that cancer might return to the same or a different part of the body.
- Chronic pain, symptoms of depression and anxiety, self-perceived health, and intolerance of uncertainty were also evaluated.
- Among the participants, 21 experienced a recurrence of their primary cancer and 17 were diagnosed with a subsequent malignant neoplasm.
TAKEAWAY:
- Overall, 38 (16.6%) adult survivors of childhood cancer reported clinically significant fear that their cancer would recur, and an additional 36 (15.7%) survivors experienced high levels of fear; the remaining 67.7% of participants reported minimal levels of fear.
- Survivors who were unemployed (prevalence ratio [PR], 2.5) were more likely to experience a clinically significant fear of recurrence, as were survivors who had undergone pelvic radiation (PR, 2.9) or limb-sparing or amputation surgery (PR, 2.4).
- Survivors who had elevated anxiety or depression (PR, 2.6) or both (PR, 3.2) were more likely to experience a clinically significant fear of recurrence, as were survivors who had a chronic neurologic health condition (PR, 3.3) or who perceived their health status to be poor or fair vs good to excellent (PR, 3.0).
- Among 94 participants with chronic pain, 25.5% reported clinically significant fear and 13.8% reported high levels of fear. But chronic pain (PR, 1.2; 95% CI, 0.6-2.4) was not significantly associated with a clinically significant fear of recurrence in a multivariable model.
IN PRACTICE:
“These findings underscore the substantial psychological and functional burden of FCR [fear of cancer recurrence] and suggest healthcare professionals should routinely assess FCR as a part of providing comprehensive care to long-term survivors,” the authors wrote.
