Effect of progressive resistance training on health-related quality of life in the first year after breast cancer surgery - results from a randomized controlled trial.

Aims: To examine the effect of progressive resistance training (PRT) on health related quality of life and a predefined symptom cluster of pain-sleep-fatigue. Methods: This study was a planned secondary analysis of a randomized controlled trial examining the effect of PRT on prevention of arm lymphedema in a population of women between 18 and 75 years undergoing breast cancer surgery with axillary lymph node dissection. Participants were allocated by computer randomization to usual care control or a PRT intervention in a 1:1 ratio. The intervention, initiated in the third post-operative week, consisted of three times PRT per week, supervised in groups in the first 20 weeks, and self-administered in the following 30 weeks. Questionnaire assessments were made at baseline, 20 weeks and 12 months, with the European Organization for Research and Treatment in Cancer Core questionnaire (EORTC QLQ C30) and the Functional Assessment of Chronic Illness Therapy-(FACIT) fatigue questionnaire. The symptom cluster of pain-sleep-fatigue was measured with a constructed score adding EORTC C30 subscales of insomnia, pain, and fatigue. Data were treated as repeated measurements and analyzed with mixed models. Results: Among 158 recruited participants, we found a clinically relevant increased emotional functioning with nine points at both follow-ups (p = .02), and 16 and 11 points at 20 weeks and 12 months respectively (p = .04) in social functioning. Furthermore, in the subgroup of women with the symptom cluster pain-sleep-fatigue present at baseline, a significant effect was found for global health status (p = .01) and social functioning (p = .02). Conclusion: To our knowledge, this is the first study to report clinically relevant effects of PRT on social and emotional functioning in the first postoperative year after breast cancer surgery. Furthermore, a subgroup of women with the pain-sleep-fatigue symptom cluster had particular benefit from PRT on global health status and social functioning.

Educational level and the risk of depression after prostate cancer.

Background: The risk of depression is inversely associated with socioeconomic position in the general population; however, studies on the association in cancer populations are limited. The aim was to investigate if shorter education was associated with a higher risk of depression following prostate cancer diagnosis. Material and methods: This is a cohort study among participants in the Danish prospective Diet, Cancer and Health (DCH) study including 2337 men diagnosed with prostate cancer between 1997 and 2014. Primary outcome was indication of moderate to severe depression, defined as either a first hospital contact for depression or first use of antidepressants. The main indicator of socioeconomic position was education categorized into short (<9 years of education), medium (9-12 years) and long (>12 years). We retrieved information on education, depression and cohabitation status from Danish National Registries. Information on stage, primary treatment, lifestyle and anthropometry was obtained from medical records and questionnaires. Data were analyzed using Cox proportional hazards models adjusted for possible confounders and mediators. Results: The hazard of first depression was 1.86-fold higher (95% CI, 1.36-2.54) in prostate cancer patients with short education compared to those with long education. Adjustment for stage and primary treatment did not change the HRs, while adding comorbidity and lifestyle factors resulted in an HR of 1.65 (95% CI, 1.19-2.29). Men with medium education had a non-statistically significant 1.23-fold higher hazard of depression (95% CI, 0.95-1.59) than men with long education in the fully adjusted model. Educational differences were present in the cumulative incidence of first depression among cancer-free DCH study participants, but the level of first depression was substantially lower in this population than in prostate cancer patients. Conclusions: We found indication of social inequality in depression following prostate cancer. Patients and particularly men with short education might benefit from psychosocial intervention and support.

Antidepressant prescriptions and associated factors in men with prostate cancer and their female partners.

PURPOSE: To estimate the risk of first-time antidepressant prescriptions as a proxy for depression or anxiety and associated risk factors in patients with prostate cancer and their female partners. METHODS: We followed all men (n = 25,126) and their female cohabiting partners (n = 8785) without a history of cancer or antidepressants from the Danish Diet, Cancer and Health cohort from 1997 to 2014 or 2010, respectively. We estimated the cumulative incidence of first-time antidepressant prescriptions in men with prostate cancer compared with cancer-free men and their respective female partners, using the Danish National Prescription Registry. Sociodemographic, lifestyle-related, and clinical risk factors were assessed using Cox regression models. RESULTS: A total of 1828 men were diagnosed with prostate cancer of whom 15% received antidepressants. The unadjusted hazard ratio of antidepressant prescription was 2.18 (95%CI, 1.92, 2.48) for men with prostate cancer and 1.27 (95%CI, 0.87, 1.85) for their partners, compared with cancer-free men and their partners, respectively. After adjusting for sociodemographic, lifestyle-related, and comorbidity factors, this risk was 2-fold to 4-fold increased among patients, but not significantly increased among partners. Significant risk factors among patients were curative and palliative treatment (vs. active surveillance and watchful waiting), nonlocalized disease, and short education. CONCLUSIONS: Men with prostate cancer have a higher risk of receiving antidepressant medication than cancer-free men. Clinical characteristics can help clinicians in identifying patients at a high risk of depression or anxiety. IMPLICATIONS FOR CANCER SURVIVORS: Men with prostate cancer who experience symptoms of depression or anxiety should seek professional help early on. Patient education could aid in raising awareness and reducing the stigma associated with mental disorders.
