Factors associated with depression in disease-free stomach cancer survivors

Abstract

Context: Depression in cancer survivors affects the rest of their lives in many ways.

Objectives: To estimate the prevalence of depression and identify associated factors in disease-free stomach cancer survivors.

Methods: We enrolled 391 stomach cancer survivors who had been disease-free for at least one year after surgery from the cancer registries of two hospitals in Korea. Stomach cancer survivors were mailed a survey that included the Beck Depression Inventory, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, and the associated stomach module, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Stomach Cancer Module 22.

Results: Forty-four percent of survivors suffered from depression, and more women (49%) than men (42%) had high depression scores (Beck Depression Inventory >13). In multiple logistic regression analysis, lower income (odds ratio [OR] 2.49; 95% CI 1.64-3.78), problems with care before treatment (OR 1.92; 95% CI 1.23-2.98), body image change (OR 2.23; 95% CI 1.41-3.53), and symptoms of fatigue (OR 3.11; 95% CI 1.49-6.52), dyspnea (OR 2.57; 95% CI 1.48-4.45), or insomnia (OR 4.51; 95% CI 1.88-10.83) were associated with depression.

Conclusion: The prevalence of depression was high in stomach cancer survivors even after the completion of treatment, especially among those with problems amenable to treatment, and we identified the associated factors. We suggest that stomach cancer survivors should be screened for depression after the end of treatment.
