Fear of cancer recurrence inventory scores and their correlation with quality of life and stress levels in breast cancer survivors.

e24073 Background: For survivors of early stage breast cancer, the fear of cancer recurrence (FCR) can be distressing. A clinical challenge is recognizing which patients reporting FCR may need psychological intervention. Prior studies have suggested clinically significant FCR if the validated FCR Inventory (FCRI) scale score is > = 22 while others suggest as low as > = 13 may be an optimal threshold. Our goal was to understand the optimal thresholds for detection of clinically significant impairments in quality of life and high levels of stress. We thus examined FCRI thresholds that optimized detection with two standardized screening modalities of quality of life and perceived stress respectively: the Functional Assessment of Cancer Therapy-General (FACT-G) and the Perceived Stress Scale (PSS). Methods: A previously published cohort of breast cancer survivors at our institution consented to complete self-reported psychological measures and gave access to their medical records. The 2 measures being compared to the FCRI were PSS and FACT-G. FCRI, is a 9-item self-report measure, that evaluates worry about health status and illness returning, triggers that influence worry, uncertainty, and the concerns of significant others. FACT-G, a 28-item self-report measure, assesses quality of life in cancer patients, including physical well-being, social/family well-being, emotional well-being, and functional well-being; we examined the binary threshold score for reduced health related quality of life ( < = 62) vs not reduced health related quality of life (> 62). PSS, assesses the degree to which situations in one’s life are appraised as stressful; we examined the threshold score for low stress (0-13) vs moderate or high stress ( > 13). Sensitivity (Sen) and specificity (Spe) were calculated for each cutoff value for the FCRI score between 16 and 22 (two proposed cutoffs) when compared to the FACT-G and the PSS binary cut points. Results: A total of 177 breast cancer survivors participated in the study. The mean age of participants was 57.6 (SD 13.1) years. Mean scores were 18.6 (SD 7.5) for the FCRI (n = 170), 13.92 (SD 7.0) for the PSS (n = 176) and 80.6 (SD 14.9) for the FACT-G (n = 155). FCRI > = 20 appeared to optimize sensitivity and specificity both on the FACT-G (Sen: 82.4, Spe: 56.1) and PSS (Sen: 63.2 Spe: 69.1) in our patient population. Conclusions: Our results suggest that a FCRI cutoff of 20 may optimize inclusion of patients likely to have poorer quality of life and higher levels of stress. This may allow for more patients in this vulnerable population to be identified for possible intervention, without losing specificity to those with significant distress.[Table: see text]
