RESUMEN
BACKGROUND: Prior studies of suicide risk among prostate cancer patients are conflicting. We compared the risk of suicide in prostate cancer patients to cancer-free men including adjustment for clinical stage, socioeconomic position, somatic comorbidity, and previous depression. MATERIALS AND METHODS: A cohort of 37,527 men diagnosed with prostate cancer in Denmark during 1998-2011 was identified in the Danish Prostate Cancer Registry (DaPCaR) and compared with 357,384 cancer-free men matched by age at the time of diagnosis. The primary outcome was death from suicide. Data were analyzed using cumulative incidence functions and multivariable Cox regression models. RESULTS: Among prostate cancer patients, 3813 had a previous depression, defined as filed antidepressant prescription within three years before diagnosis. In the study period, 108 prostate cancer patients were registered with suicide as the cause of death, hereof 26 with previous depression. There was no difference in the cumulative incidence of suicide between prostate cancer patients and cancer-free men. There was no effect modification of previous depression on the risk of suicide (p = .12). The hazard ratio (HR) for suicide varied with time since diagnosis. A sensitivity analysis showed that the risk of suicide was highest within the first year of diagnosis where prostate cancer patients had a 1.70-fold increased hazard compared with cancer-free men (95% CI, 1.11-2.59). Men with prostate cancer and previous depression had a three-fold increased hazard for suicide compared with prostate cancer patients without a history of depression (HR 2.84, 95% CI, 1.82-4.45). CONCLUSION: The absolute risk of suicide is low following a prostate cancer diagnosis. Time since diagnosis and a history of depression was associated with the highest risk of suicide. Healthcare professionals should be aware of an increased risk of suicide among men with previous depression, especially in the immediate aftermath of the diagnosis.

OBJECTIVE: To compare the risk of depression after diagnostic workup for prostate cancer (PCa), regardless of the histopathologic outcome, with that of a cancer-free population. METHODS: A nationwide cohort of Danish men who had a prostatic biopsy sample in 1998-2011 was identified from the Danish Prostate Cancer Registry and compared to an age-matched cohort from the background population. Men with other cancers, major psychiatric disorder, or prior use of antidepressants were excluded. The risk of depression defined as hospital contact for depression or prescription for antidepressants was determined from cumulative incidence functions and multivariate Cox regression models. RESULTS: Of 54,766 men who underwent diagnostic workup for PCa, benign results were found for 21,418 and PCa was diagnosed in 33,347. During up to 18 years of follow-up, the adjusted hazard of depression was higher in men with PCa than in the background population, with the highest risk in the two years after diagnosis (hazard ratio (HR) 2.77, 95% CI 2.66-2.87). Comorbidity and lowest or highest income were significant risk factors for depression and the cumulative incidence was substantially higher in men with metastatic or high-risk disease. In men with benign histopathology the HR for depression was 1.22 (95% CI 1.14-1.31) in the first two years but no different from the background population after that. CONCLUSIONS: Diagnostic workup for PCa is associated with an increased risk of depression, mainly among men with a diagnosis of PCa. Clinicians should be aware of depressive symptoms in prostate cancer patients.

BACKGROUND: The extent to which positive surgical margins (PSM) affect the risk of subsequent salvage radiation therapy (sRT) or androgen depletion therapy (ADT) following radical prostatectomy (RP) is not well described. Initiation of additional therapies after RP depend on patient preference, individual factors, local guidelines, and life expectancy. The aim of this study was to analyze differences between margin status in risk of subsequent treatment for PCa following RP in a retrospective population-based cohort from Denmark. METHODS: Patients who underwent RP were identified in The Danish Prostate Cancer Registry (DaPCaR). Subsequent sRT and ADT were assessed in uni- and multivariate settings and validated with receiver operating characteristic (ROC). RESULTS: PSM was associated with an increased risk of sRT (HR = 1.85, p < .001) and receiving ADT (HR:1.39, p = .007). Margin status only had a minor impact on the predictive ability for sRT (area under the curve (AUC): p < .001) and no significant impact for subsequent ADT (AUC: p = 1). Significant inter-institutional difference in the association between PSM with sRT or ADT was observed. CONCLUSION: PSM is associated with the risk of sRT and initiation of ADT, however this association is weak. Our results underline that factors beyond tumor characteristics play a major role for initiation of sRT and ADT.

PURPOSE: The Danish follow-up program for breast cancer (BC) patients has recently been changed. Today most patients are offered open access to an outpatient clinic, whereas the scheduled visits are phased out. This strategy has been studied in regards to psychological and health-related quality of life outcomes, but not in regards to detection of recurrence and survival. The aim of this study was to quantify the recurrences detected at scheduled outpatient visits in Denmark before the implementation of revised follow-up guidelines. METHODS: We conducted a cross-sectional study among 310 patients with recurrent BC. Information was retrieved on tumor characteristics, type of visit when recurrence was detected, recurrence localization, symptoms reported, and duration of symptoms from the Danish Breast Cancer Group database and medical records. RESULTS: The recurrences were locoregional (26%), locoregional and distant (15%), or distant (59%). Among patients still in outpatient follow-up (n = 199), recurrence was detected at a patient-requested extra outpatient visit (15%), by the general practitioner or other specialist (47%), at a scheduled outpatient visit (21%), or on a scheduled mammogram (11%). Among patients with recurrences detected at scheduled outpatient visits, the majority (88%) reported symptoms related to the recurrence. Most frequent symptoms were pain (37%), dyspnoea (15%), and fatigue (12%). CONCLUSIONS: One-fifth of BC recurrences among patients attending outpatient follow-up were detected at scheduled outpatient visits. Very few of these were asymptomatic. Whether there will be a delay in detection of the symptomatic recurrences when the number of visits is reduced is unknown.

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.

Background: High socioeconomic position is associated with better prognosis in prostate cancer patients but it is unknown if part of this association may be explained by socioeconomic differences in severe late effects. We investigated the association between education as an indicator for socioeconomic position and cardiovascular events after prostate cancer and if such associations were mediated by differences in lifestyle, cardiovascular risk factors and prostate cancer treatment. Material and methods: We identified 1980 men diagnosed with prostate cancer from 1993 to 2014 among participants in the Danish Diet, Cancer and Health study. Individual level information on education, lifestyle, cardiovascular risk factors and prostate cancer clinical information were obtained from questionnaires, registries and medical records. The Cox proportional hazards models were used to evaluate the risk of incident acute myocardial infarction, ischemic stroke and heart failure during up to 18 years of follow-up for men with short (<9 years) or medium (9-12 years) compared with long education (>12 years). Results: Compared to men with long education, we found an increased risk of acute myocardial infarction in men with medium and short education (HR 3.14, 95% CI 1.53-6.47 and HR 2.14, 95% CI 0.82-5.58, respectively). Adjusting for stage, first-line treatment, lifestyle and cardiovascular risk factors did not change the HRs substantially (adjusted HRs 3.04, 95% CI 1.47-6.31 and 2.07, 95% CI 0.78-5.53, respectively). There were no educational differences in risk for ischemic stroke or heart failure. Conclusions: The risk of acute myocardial infarction was increased in prostate cancer patients with short or medium education compared with long education. Although the educational inequality did not seem to be explained by differences in treatment, lifestyle or cardiovascular risk factors, monitoring of cardiovascular health and health promotion should involve all prostate cancer patients regardless of social position to ensure best prognosis for all.

BACKGROUND: Most cancer survivors receive follow-up care after completion of treatment with the primary aim of detecting recurrence. Traditional follow-up consisting of fixed visits to a cancer specialist for examinations and tests are expensive and may be burdensome for the patient. Follow-up strategies involving non-specialist care providers, different intensity of procedures, or addition of survivorship care packages have been developed and tested, however their effectiveness remains unclear. OBJECTIVES: The objective of this review is to compare the effect of different follow-up strategies in adult cancer survivors, following completion of primary cancer treatment, on the primary outcomes of overall survival and time to detection of recurrence. Secondary outcomes are health-related quality of life, anxiety (including fear of recurrence), depression and cost. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, four other databases and two trials registries on 11 December 2018 together with reference checking, citation searching and contact with study authors to identify additional studies. SELECTION CRITERIA: We included all randomised trials comparing different follow-up strategies for adult cancer survivors following completion of curatively-intended primary cancer treatment, which included at least one of the outcomes listed above. We compared the effectiveness of: 1) non-specialist-led follow-up (i.e. general practitioner (GP)-led, nurse-led, patient-initiated or shared care) versus specialist-led follow-up; 2) less intensive versus more intensive follow-up (based on clinical visits, examinations and diagnostic procedures) and 3) follow-up integrating additional care components relevant for detection of recurrence (e.g. patient symptom education or monitoring, or survivorship care plans) versus usual care. DATA COLLECTION AND ANALYSIS: We used the standard methodological guidelines by Cochrane and Cochrane Effective Practice and Organisation of Care (EPOC). We assessed the certainty of the evidence using the GRADE approach. For each comparison, we present synthesised findings for overall survival and time to detection of recurrence as hazard ratios (HR) and for health-related quality of life, anxiety and depression as mean differences (MD), with 95% confidence intervals (CI). When meta-analysis was not possible, we reported the results from individual studies. For survival and recurrence, we used meta-regression analysis where possible to investigate whether the effects varied with regards to cancer site, publication year and study quality. MAIN RESULTS: We included 53 trials involving 20,832 participants across 12 cancer sites and 15 countries, mainly in Europe, North America and Australia. All the studies were carried out in either a hospital or general practice setting. Seventeen studies compared non-specialist-led follow-up with specialist-led follow-up, 24 studies compared intensity of follow-up and 12 studies compared patient symptom education or monitoring, or survivorship care plans with usual care. Risk of bias was generally low or unclear in most of the studies, with a higher risk of bias in the smaller trials. Non-specialist-led follow-up compared with specialist-led follow-up It is uncertain how this strategy affects overall survival (HR 1.21, 95% CI 0.68 to 2.15; 2 studies; 603 participants), time to detection of recurrence (4 studies, 1691 participants) or cost (8 studies, 1756 participants) because the certainty of the evidence is very low. Non-specialist- versus specialist-led follow up may make little or no difference to health-related quality of life at 12 months (MD 1.06, 95% CI -1.83 to 3.95; 4 studies; 605 participants; low-certainty evidence); and probably makes little or no difference to anxiety at 12 months (MD -0.03, 95% CI -0.73 to 0.67; 5 studies; 1266 participants; moderate-certainty evidence). We are more certain that it has little or no effect on depression at 12 months (MD 0.03, 95% CI -0.35 to 0.42; 5 studies; 1266 participants; high-certainty evidence). Less intensive follow-up compared with more intensive follow-up Less intensive versus more intensive follow-up may make little or no difference to overall survival (HR 1.05, 95% CI 0.96 to 1.14; 13 studies; 10,726 participants; low-certainty evidence) and probably increases time to detection of recurrence (HR 0.85, 95% CI 0.79 to 0.92; 12 studies; 11,276 participants; moderate-certainty evidence). Meta-regression analysis showed little or no difference in the intervention effects by cancer site, publication year or study quality. It is uncertain whether this strategy has an effect on health-related quality of life (3 studies, 2742 participants), anxiety (1 study, 180 participants) or cost (6 studies, 1412 participants) because the certainty of evidence is very low. None of the studies reported on depression. Follow-up strategies integrating additional patient symptom education or monitoring, or survivorship care plans compared with usual care: None of the studies reported on overall survival or time to detection of recurrence. It is uncertain whether this strategy makes a difference to health-related quality of life (12 studies, 2846 participants), anxiety (1 study, 470 participants), depression (8 studies, 2351 participants) or cost (1 studies, 408 participants), as the certainty of evidence is very low. AUTHORS' CONCLUSIONS: Evidence regarding the effectiveness of the different follow-up strategies varies substantially. Less intensive follow-up may make little or no difference to overall survival but probably delays detection of recurrence. However, as we did not analyse the two outcomes together, we cannot make direct conclusions about the effect of interventions on survival after detection of recurrence. The effects of non-specialist-led follow-up on survival and detection of recurrence, and how intensity of follow-up affects health-related quality of life, anxiety and depression, are uncertain. There was little evidence for the effects of follow-up integrating additional patient symptom education/monitoring and survivorship care plans.

BACKGROUND: Development of depression in prostate cancer patients depends on multiple disease- and patient-related factors. OBJECTIVE: To investigate the risk of depression following radical prostatectomy focussing on the impact of surgery and subsequent treatment with salvage radiation or androgen deprivation therapy. DESIGN, SETTING, AND PARTICIPANTS: A population-based cohort study of 5570 men who underwent radical prostatectomy in Denmark from 1998 to 2011 was identified in the Danish Prostate Cancer Registry. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Data on covariates and primary outcome defined as a hospital contact for depression or a redeemed antidepressant prescription were obtained from nationwide Danish registries. The risk of depression was evaluated using cumulative incidence functions and Cox models with time since surgery as an underlying time scale. Exposure to salvage procedures was included as time-varying covariates, and analyses were adjusted for confounders. RESULTS AND LIMITATIONS: The cumulative incidence of depression was increased in men who had undergone surgery compared with cancer-free men throughout follow-up of up to 18yr, particularly among men on androgen deprivation therapy. Compared with no subsequent treatment, the risk of depression was increased with subsequent androgen deprivation therapy (hazard ratio [HR] 1.8, 95% confidence interval [CI] 1.4-2.3), salvage radiation (HR 1.3, 95% CI 1.0-1.6), and the treatments combined (HR 2.2, 95% CI 1.8-2.8) after adjustments for age, year of surgery, income, and cohabitation status. Further adjustment for comorbidity hardly changed the estimates. CONCLUSIONS: Radical prostatectomy and subsequent salvage procedures increase the risk of depression, and men with subsequent androgen deprivation therapy are mainly at risk. Clinicians should thus be aware of depressive symptoms in patients receiving treatment for postsurgical relapse. PATIENT SUMMARY: In a population-based study, we found that radical prostatectomy and subsequent treatments with either radiation or endocrine manipulation significantly increased the risk of developing clinical depression.

PURPOSE: To investigate whether health literacy (HL) among informal caregivers of breast cancer (BC) survivors is associated with patient psychological outcomes. METHODS: We used data (n = 340 pairs) from baseline questionnaires administered in the MyHealth trial investigating nurse-led BC follow-up. All BC survivors and their invited caregivers were included immediately after completion of primary treatment. We performed multivariate regression analyses to examine the association between caregiver HL (nine dimensions as measured by the Health Literacy Questionnaire) as exposure and patient depression, anxiety, and health-related quality of life (HQoL) as outcomes. We further examined whether any association differed according to type of caregiver, patient HL, and patient activation (skill in managing one's health). RESULTS: Three dimensions, "ability to engage with providers" (ß = - 0.2), "navigating the system" (ß = - 0.2), and "understand health information" (ß = - 0.2), were significantly associated with lower patient depression (p < 0.05), while four dimensions, "having sufficient information" (ß = 0.3), "navigating the system" (ß = 0.2), "find health information" (ß = 0.2), and "understand health information" (ß = 0.2), were significantly associated with better patient HQoL (p < 0.05). No significant associations were found for anxiety. Patient HL and activation did not significantly modify the associations, while certain associations for depression were stronger in patients with non-partner caregivers. CONCLUSIONS: The HL of informal caregivers may play an important role in optimizing psychological outcomes in cancer survivors. IMPLICATIONS FOR CANCER SURVIVORS: Involving informal caregivers, who can provide support related to health information and services, may be beneficial for the psychological well-being of cancer survivors.
