Objective: An increasing number of hematologic cancer patients outlive 10 years past diagnosis. Nevertheless, few studies investigated psychological strain in this patient group beyond 5 years after diagnosis. We conducted a registry-based investigation of risk for depression and anxiety among long-term hematologic cancer survivors up to 26 years after diagnosis compared to the general population.
Methods: In this cross-sectional postal survey, cancer survivors were recruited through 2 regional cancer registries in Germany. Depression (Patient Health Questionnaire-9) and anxiety (Generalized Anxiety Disorder-7) were assessed. Survivor data were compared to age- and gender-matched comparison groups (CG) randomly drawn from large representative samples (N > 5,000).
Results: Out of 2,001 eligible patients, 46% participated (n = 922). Survivors were significantly more likely than the CG to report elevated depressive (relative risk [RR] = 3.1; 95% confidence interval [CI]: 2.2-4.3) and anxious symptomatology (RR = 1.7; 95% CI: 1.2-2.3). Depression scores remained high even in the survivor Group 12-26 years after diagnosis. RR for anxiety decreased to values comparable to the CG. Younger and middle-aged survivors (≤65 years) were at highest relative and absolute risk to be psychologically impaired.
Conclusion: This study shows that depression rather than anxiety is a prominent problem in long-term survivors of hematologic cancer. The results stress the importance of monitoring patients even years after diagnosing and supplying psychosocial support to patients in need.
