Prevalence of and factors associated with anxiety and depression in Korean patients with newly diagnosed advanced gastrointestinal cancer

BACKGROUND/AIMS: The purpose of the present study was to assess the prevalence of and factors associated with anxiety and depression in Korean patients with advanced gastrointestinal cancer. METHODS: One hundred and twenty consecutive patients with newly diagnosed, advanced gastrointestinal cancer who were scheduled to receive palliative chemotherapy between July 2012 and June 2014 were enrolled in this observational prospective study. Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS) and Patient Health Questionnaire-9 (PHQ-9). RESULTS: Thirty-seven patients (30.8%) had anxiety or depression with clinical significance according to HADS or PHQ-9. Multivariate analysis identified lower performance status (odds ratio [OR], 4.19; 95% confidence interval [CI], 1.22 to 14.35; p = 0.023), gastric cancer (OR, 5.39; 95% CI, 0.37 to 78.23; p = 0.018), and knowledge of advanced cancer (OR, 15.07; 95% CI, 1.80 to 125.90; p = 0.012) as significantly associated with anxiety or depression. Twenty-one patients with anxiety or depression visited the psycho-oncologic clinic. In these patients, PHQ-9 score (p = 0.008), global health status (p = 0.023), fatigue (p = 0.047), and appetite loss (p = 0.006) improved from baseline to 3 months after study enrollment. CONCLUSIONS: Approximately 30% of Korean patients with advanced gastrointestinal cancer had anxiety or depression. The prevalence of anxiety or depression was higher in patients with poor performance status, gastric cancer, or knowledge of advanced cancer. Psychiatric interventions may be effective in reducing depression and improving quality of life in cancer patients with anxiety or depression.

Anxiety and Depression as Predictive Factors for Quality of Life in Patients with Advanced Gastrointestinal Cancer

PURPOSE: The purpose of the present study was to assess factors associated with quality of life (QOL) and to determine whether anxiety and depression are predictive of QOL in patients with advanced gastrointestinal cancer at initial diagnosis and during the treatment process. METHODS: One hundred and twenty patients with gastrointestinal cancer requiring palliative chemotherapy were enrolled. RESULTS: At baseline, depression, performance status, and anxiety accounted for 55.0% (p<.001) of the variance in global health status score, depression accounted for 22.0% (p<.001) of the variance in functional scales score, and anxiety accounted for 19.0% (p<.001) of the variance in symptom scales score. At 3 months, depression, pain, and performance status accounted for 72.0% (p<.001) of the variance in global health status score, 76.0% (p<.001) of the variance in functional scales score, and 74.0% (p<.001) of the variance in symptom scales score. CONCLUSION: Anxiety and depression were significant predictive factors of QOL in patients with advanced gastrointestinal cancer. Depression and performance status were significant predictive factors of QOL at both baseline and 3 months, and anxiety and pain were significant predictive factors of QOL at baseline and 3 months, respectively.
