Fear of cancer recurrence in long-term colorectal cancer survivors: a nationwide cross-sectional study.

PURPOSE

Knowledge about fear of cancer recurrence (FCR) among recurrence-free long-term colorectal cancer survivors (CRCS) is limited. This national cross-sectional study aimed to (1) assess the prevalence and correlates of FCR among CRCS; (2) investigate associations between colorectal cancer-specific symptoms and FCR; and (3) identify predictors of interest in engaging in FCR treatment.

METHODS

We identified 9638 living Danish CRCS, age above 18 years, diagnosed between 2014 and 2018 through the Danish Clinical Registries. Electronic surveys were distributed between May 2023 and May 2024. FCR was measured on the Fear of Cancer Recurrence Inventory - Short Form (FCRI-SF). Associations with colorectal cancer-specific physical symptoms and psychological symptoms were analyzed using logistic regression models.

RESULTS

Of 5480 respondents (56.9%; mean age: 73, range (30-99; 42% female), 5.3% of survivors reported clinical FCR (cFCR). In multivariate analyses, having severe abdominal pain (OR 8.7 (95% CI 4.8-15.8)), abdominal bloating, tension, or heaviness (OR 10.0 (95% CI (6.1-16.3)) and tiredness (OR 7.1 (95% CI (4.1-12.1)) were associated with increased odds of cFCR, as were psychological symptoms (health anxiety; OR 19.7 (95% CI (13.5-28.6)), anxiety; OR 11.2 (95% CI (6.4-19.6)), depression; OR 5.5 (95% CI (2.6-11.9)) compared to no FCR. Among those with cFCR, 75% were interested in treatment, with higher interest among males and chemotherapy recipients.

CONCLUSION

FCR severity is strongly associated with specific colorectal symptoms, tiredness, and psychological symptoms.

IMPLICATIONS FOR CANCER SURVIVORS

Addressing cancer-specific physical symptoms may be a promising strategy for reducing FCR.
