Depression Negatively Impacts Survival of Patients with Metastatic Prostate Cancer

Mortality Risks Associated with Depression in Men with Prostate Cancer

BACKGROUND

Men diagnosed with prostate cancer (PC) have an increased risk of depression; however, it is unclear to what extent depression affects long-term survival. A better understanding of such effects is needed to improve long-term care and outcomes for men with PC.

OBJECTIVE

To determine the associations between major depression and mortality in a national cohort of men with PC.

DESIGN, SETTING, AND PARTICIPANTS

A national cohort study was conducted of all 180 189 men diagnosed with PC in Sweden during 1998-2017. Subsequent diagnoses of major depression were ascertained from nationwide outpatient and inpatient records through 2018.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Deaths were identified from nationwide records through 2018. Cox regression was used to compute hazard ratios (HRs) for all-cause mortality associated with major depression, adjusting for sociodemographic factors and comorbidities. Subanalyses assessed differences by PC treatment during 2005-2017. PC-specific mortality was examined using competing risks models.

RESULTS AND LIMITATIONS

In 1.3 million person-years of follow-up, 16 134 (9%) men with PC were diagnosed with major depression and 65 643 (36%) men died. After adjusting for sociodemographic factors and comorbidities, major depression was associated with significantly higher all-cause mortality in men with high-risk PC (HR, 1.50; 95% confidence interval [CI], 1.44-1.55) or low- or intermediate-risk PC (1.64; 1.56-1.71). These risks were elevated regardless of PC treatment or age at PC diagnosis, except for youngest men (<55 yr) in whom the risks were nonsignificant. Major depression was also associated with increased PC-specific mortality in men with either high-risk PC (HR, 1.35; 95% CI, 1.28-1.43) or low- or intermediate-risk PC (1.42; 1.27-1.59). This study was limited to Sweden and will need replication in other countries when feasible.

CONCLUSIONS

In this national cohort of men with PC, major depression was associated with ∼50% higher all-cause mortality. Men with PC need timely detection and treatment of depression to support their long-term outcomes and survival.

PATIENT SUMMARY

In this report, we examined the effects of depression on survival in men with prostate cancer. We found that among all men with prostate cancer, those who developed depression had a 50% higher risk of dying than those without depression. Men with prostate cancer need close monitoring for the detection and treatment of depression to improve their long-term health outcomes.

Racial Disparities in Diagnosis and Treatment of Depression Associated with Androgen Deprivation Therapy for Prostate Cancer

OBJECTIVE

To analyze potential racial disparities in the diagnosis and management of depression associated with androgen deprivation therapy.

METHODS

TriNetX health record network was queried for prostate cancer patients treated with androgen deprivation therapy from 2003-2023. Differences in rates of depression diagnosis and treatment were compared between White and Black patients. Means, odds ratios, and t tests were calculated in univariate analysis with 95% confidence intervals (CI).

RESULTS

Data were queried from 93 health care organizations to yield 78,313 prostate cancer patients treated with androgen deprivation therapy. Patients on androgen deprivation therapy had 60% greater odds of developing depression vs other patients [9% vs 6%; odds ratio (OR) 1.6; 95% CI (1.5-1.7); P <.0001]. Of those with depression secondary to androgen deprivation therapy, only 35% were treated with antidepressants. After starting androgen deprivation therapy, White patients had 30% greater odds of being diagnosed with depression, compared to Black patients [10% vs 8%; OR 1.3; 95% CI (1.2-1.4); P <.001]. White patients also had higher odds of being treated with a first line antidepressant than Black patients [56% vs 48%; OR 1.4, 95% CI (1.2-1.6), P <.001].

CONCLUSION

This analysis confirms a significant association between androgen deprivation therapy and the development of clinical depression, and highlights its medical undertreatment. Importantly, our findings also indicate significant racial disparities in the identification and treatment of depression. Routine screening initiatives that account for social determinants of health may alleviate this disparity. Limitations of this study include retrospective design and lack of data describing severity of depression, which might correlate with need for medication.

Psychological Distress, Emergency Room Utilization, and Mortality Risk Among US Adults With History of Prostate Cancer

PURPOSE

Adults with a history of prostate cancer experience several physical and mental stressors. However, limited information is available about the prevalence of psychological distress in this population and its association with clinical outcomes in a nationally representative sample.

METHODS

We identified adults with history of prostate cancer from a nationally representative cohort (2000-2018 US National Health Interview Survey) and its linked mortality files through December 31, 2019. The six-item Kessler Psychological Distress Scale (K6) was used to assess psychological distress. The associations between psychological distress severity, emergency room (ER) usage, and mortality risk were estimated using multivariable logistic and Cox proportional hazards models, which were both adjusted for age, survey year, race/ethnicity, region, education, health insurance, comorbidities, functional limitations, and time since cancer diagnosis.

RESULTS

Among the 3,451 adults with history of prostate cancer surveyed, 96 (2.4%), 434 (11.3%), and 2,921 (86.3%) reported severe, moderate, or low/no mental distress, respectively. During the 12 months preceding the survey, 812 (22.8%) adults with history of prostate cancer visited the ER. After a median follow-up of 81 months, 937 (25.5%) deaths occurred. Compared with participants with low/no mental distress, those with severe mental distress reported the highest utilization of the ER (adjusted odds ratio [aOR], 2.57 [95% CI, 1.51 to 4.37]) and exhibited the highest all-cause mortality (adjusted hazard ratio [aHR], 1.83 [95% CI, 1.29 to 2.60]), followed by those with moderate mental distress (ER use aOR, 1.76 [95% CI, 1.29 to 2.42]; all-cause mortality aHR, 1.22 [95% CI, 0.92 to 1.62]).

CONCLUSION

Among US adults with history of prostate cancer, psychological distress was associated with increased ER use and mortality risk. Notably, severe psychological distress was correlated with the highest rates of ER visits and mortality risk. However, given the retrospective nature of this study, uncontrolled confounding variables need to be considered when interpreting the findings.

Racial/Ethnic Disparity in the Relationship of Mental and Physical Health With Colorectal Cancer Screening Utilization Among Breast and Prostate Cancer Survivors

PURPOSE

We examined colorectal cancer (CRC) screening utilization among non-Hispanic White, non-Hispanic Black (NHB), non-Hispanic other (NHO)/Hispanic cancer survivors. We also determined whether experiencing poor physical and/or mental health affects CRC screening utilization in breast and prostate cancers across different racial/ethnic groups.

METHODS

Data from years 2016, 2018, and 2020 of the Behavioral Risk Factor Surveillance System on 3,023 eligible treatment-utilizing cancer survivors with complete treatment were used. We performed descriptive statistics and multivariable logistic regression to examine the mentioned association.

RESULTS

Among 3,023 eligible survivors, 67.7% of NHO/Hispanic survivors demonstrated lower CRC screening use compared with non-Hispanic White (82%) and NHB (89%) survivors (P < .001). In multivariable analysis, having frequent (14-30 days) poor mental health was associated with lower odds of receiving CRC screening among NHB (odds ratio [OR], 0.32; 95% CI, 0.11 to 0.95) and NHO/Hispanic (OR, 0.39; 95% CI, 0.18 to 0.81) survivors. Similar results in physical health were also found in NHB (OR, 0.34; 95% CI, 0.13 to 0.91) and NHO/Hispanic (OR, 0.22; 95% CI, 0.05 to 0.91) groups. Among those experienced both frequent poor mental and physical health, NHB/NHO/Hispanic were less likely to be screened for CRC (OR, 0.05; 95% CI, 0.02 to 0.10).

CONCLUSION

NHO/Hispanic survivors demonstrated lower CRC screening use. Frequent poor mental and/or physical health was strongly associated with lower CRC screening use among NHB and NHO/Hispanic survivors. Our study suggests that cancer survivorship care considering mental and physical health status may improve adherence to CRC screening recommendation (for secondary cancer prevention) for NHB, NHO, and Hispanic survivors.

What Proportion of Patients With Musculoskeletal Sarcomas Demostrate Symptoms of Depression or Anxiety?

BACKGROUND

It is estimated that the 12-month prevalence of depression in the United States is 8.6%, and for anxiety it is 2.9%. Although prior studies have evaluated depression and anxiety in patients with carcinoma, few have specifically evaluated patients with sarcoma, who often have unique treatment considerations such as mobility changes after surgery.

QUESTIONS/PURPOSES

We evaluated patients with sarcoma seen in our orthopaedic oncology clinic to determine (1) the proportion of patients with depression symptoms, symptom severity, how many patients triggered a referral to mental health professionals based upon our prespecified cutoff scores on the nine-item Patient Health Questionnaire (PHQ-9), and if their symptoms varied by disease state; (2) the proportion of patients with anxiety symptoms, symptom severity, how many patients triggered a referral to mental health professionals based upon our prespecified cutoff scores on the seven-item Generalized Anxiety Disorder Scale (GAD-7), and if they symptoms varied by disease state; (3) whether other factors were associated with the proportion and severity of symptoms of anxiety or depression, such as tumor location in the body (axial skeleton, upper extremity, or lower extremity), general type of tumor (bone or soft tissue), specific diagnosis, use of chemotherapy, length of follow-up (less than 1 year or greater than 1 year), and gender; and (4) what proportion of patients accepted referrals to mental health professionals, when offered.

METHODS

This study was a cross-sectional survey study performed at a single urban National Cancer Institute-designated Comprehensive Cancer Center from April 2021 until July 2021. All patients seen in the orthopaedic clinic 18 years of age and older with a diagnosis/presumed diagnosis of sarcoma were provided the PHQ-9 as well as the GAD-7 in our clinic. We did not track those who elected not to complete the surveys. Surveys were scored per survey protocol (each question was scored from 0 to 3 and summed). Specifically, PHQ-9 scores the symptoms of depression as 5 to 9 (mild), 10 to 14 (moderate), 15 to 19 (moderately severe), and 20 to 27 (severe). The GAD-7 scores symptoms of anxiety as 5 to 9 (mild), 10 to 14 (moderate), and 15 to 21 (severe). Patients with PHQ-9 or GAD-7 scores of 10 to 14 were referred to social work and those with scores 15 or higher were referred to psychiatry. Patients with thoughts of self-harm were referred regardless of score. Patients were divided based on disease state: patients during their initial management; patients with active, locally recurrent disease; patients with active metastatic disease; patients with prior recurrence or metastatic lesions who were subsequently treated and now have no evidence of disease (considered to be patients with discontinuous no evidence of disease); patients with no evidence of disease; and patients with an active, noncancerous complication but otherwise no evidence of disease. We additionally looked at the association of gender, chemotherapy administration, and tumor location on survey responses. Data are summarized using descriptive statistics. Differences across categories of disease state were tested for statistical significance using Kruskal-Wallis tests for continuous variables and Fisher exact tests for categorical variables as well as pairwise Wilcoxon rank sum tests.

RESULTS

Overall, symptoms of depression were seen in 35% (67 of 190) of patients, at varying levels of severity: 19% (37 of 190) had mild symptoms, 9% (17 of 190) had moderate symptoms, 6% (12 of 190) had moderately severe symptoms, and 1% (1 of 190) had severe symptoms. Depresssion symptoms severe enough to trigger a referral were seen in 17% (32 of 190) of patients overall. Patients scored higher on the PHQ-9 during their initial treatment or when they had recurrent or metastatic disease, and they were more likely to trigger a referral during those timepoints as well. The mean PHQ-9 was 5.7 ± 5.8 during initial treatment, 6.1 ± 4.9 with metastatic disease, and 7.4 ± 5.2 with recurrent disease as compared with 3.2 ± 4.2 if there was no evidence of disease (p = 0.001). Anxiety symptoms were seen in 33% (61 of 185) of patients: 17% (32 of 185) had mild symptoms, 8% (14 of 185) had moderate symptoms, and 8% (15 of 185) had severe symptoms. Anxiety symptoms severe enough to trigger a referral were seen in 16% (29 of 185) of patients overall. Patients scored higher on the GAD-7 during initial treatment and when they had recurrent disease or an active noncancerous complication. The mean GAD-7 was 6.3 ± 3.2 in patients with active noncancerous complications, 6.8 ± 5.8 in patients during initial treatment, and 8.4 ± 8.3 in patients with recurrent disease as compared with 3.1 ± 4.2 in patients with no evidence of disease (p = 0.002). Patients were more likely to trigger a referral during initial treatment (32% [9 of 28]) and with recurrent disease (43% [6 of 14]) compared with those with no evidence of disease (9% [9 of 97]) and those with discontinuous no evidence of disease (6% [1 of 16]; p = 0.004). There was an increase in both PHQ-9 and GAD-7 scores among patients who had chemotherapy. Other factors that were associated with higher PHQ-9 scores were location of tumor (upper extremity versus lower extremity or axial skeleton) and gender. Another factor that was associated with higher GAD-7 scores included general category of diagnosis (bone versus soft tissue sarcoma). Specific diagnosis and length of follow-up had no association with symptoms of depression or anxiety. Overall, 22% (41 of 190) of patients were offered referrals to mental health professionals; 73% (30 of 41) accepted the referral.

CONCLUSION

When treating patients with sarcoma, consideration should be given to potential concomitant psychiatric symptoms. Screening, especially at the highest-risk timepoints such as at the initial diagnosis and the time of recurrence, should be considered. Further work should be done to determine the effect of early psychiatric referral on patient-related outcomes and healthcare costs.

Cell marathon: long-distance cell migration and metastasis-associated gene analysis using a folding paper system

A high mortality rate was found in cancer patients with distant metastasis. Development of targeted drugs for effectively inhibiting cancer metastasis is the key for increasing therapeutic success. In the current study, a folding paper system was developed to mimic a tumor-vascular interface for the study of long-distance cell migration. Correlation between the cell migration distance and metastasis-associated gene was successfully analyzed by disassembling the stacked paper construct. The result revealed that the migration distance and number of migrated cells were highly correlated to cell characteristics. Moreover, immunocytochemistry was directly conducted on the paper layer to study the signaling pathway. Kelch-like and protein tyrosine phosphatase families were examined and the PTPN13 gene was shown to regulate long-distance cell migration. By analyzing the phosphorylated mTOR, the PTPN13 gene was further confirmed to be a tumor suppressor gene that inhibits long-distance cell migration. The folding paper system provides an alternative approach for long-distance cell migration. Metastasis-associated gene expression can be analyzed to potentially develop targeted drugs for cancer metastasis inhibition.

Antidepressant medication use and prostate cancer recurrence in men with depressive disorders

Purpose

Whether treating prostate cancer survivors with a depressive disorder with antidepressants can affect their cancer outcomes is unknown. We evaluated the association between antidepressant use and prostate cancer recurrence, in survivors with comorbid depressive disorders.

Methods

We conducted a longitudinal cohort study of 10,017 men with prostate cancer (stages I–II) diagnosed who also had a comorbid depressive disorder followed a maximum of 22 years, and examined rates of biochemical recurrence by antidepressant medication use. We conducted multivariable Cox models based on time-dependent antidepressant drug use status, and examined the risk of biochemical recurrence by cumulative duration of antidepressant use.

Results

Of these 10,017 survivors, 1842 (18%) experienced biochemical recurrence over 69,500 person-years of follow-up. The prostate cancer biochemical recurrence rate was greater with antidepressant non-use (31.3/1000 person-years) compared to antidepressant use (23.5/1000 person-years). In Cox proportional hazards multivariable adjusted models, non-use of antidepressants was associated with a 34% increased risk of biochemical recurrence compared to antidepressant use (HR = 1.34, 95% CI: 1.24–1.44). Longer use of antidepressants was associated with a lower biochemical recurrence risk (P trend test < 0.001).

Conclusion

Untreated depressive disorders in prostate cancer patients may be associated with an increased risk of biochemical recurrence.

Social Support Mediates the Relationship between Body Image Distress and Depressive Symptoms in Prostate Cancer Patients

Treatments for prostate cancer (PCa), the second most common cancer in men, may affect the body image (BI) of patients, increasing the risk of negative mental health outcomes. However, an enabling social support network may be a protective factor against the effects of BI distress on health. Therefore, the present study examined the mediating role of social support in the relationship between BI distress and depressive symptoms. Data were retrospectively collected from 197 PCa patients aged from 48 to 79 years (M = 67.19; SD = 6.83). The statistical package for the social sciences with PROCESS Macro was used to assess the direct and mediating effects with bias-corrected bootstrapping (10,000 samples). Results showed that BI distress was positively associated with depressive symptoms and that social support partially mediated this relationship. Moreover, among the different sources of social support, only friend support significantly mediated the association between BI distress and depressive symptoms. This study sheds light on the crucial role of social support as a dimension that can promote health in PCa patients.

Depression, Anxiety, and Patterns of Mental Health Care Among Men With Prostate Cancer Receiving Androgen Deprivation Therapy

BACKGROUND

Androgen deprivation therapy (ADT) use is associated with an increased risk of developing depression and anxiety. Little is known about how the mental health of these men is treated.

MATERIALS AND METHODS

We identified men with prostate cancer who received ADT between 2001 and 2015 using Optum's de-identified Clinformatics Data Mart Database. We determined the incidence of depression or anxiety diagnoses, mental health treatments, and the specialty of providers initiating psychotropic medications, after the start of ADT. Outcomes were compared with those of men with prostate cancer not receiving ADT and men without prostate cancer.

RESULTS

Of 37 388 men with prostate cancer treated with ADT, 3964 (10.6%) received a new diagnosis of depression or anxiety. Of those 3964 men, 1892 (47.7%) did not receive a documented treatment, 10 (0.3%) received psychotherapy, 1321 (33.3%) a selective serotonin reuptake inhibitor, and 744 (18.8%) a benzodiazepine. The median time from initiation of ADT to a depression or anxiety diagnosis was 9.3 months. Primary care physicians were the most common prescribers of psychotropic medications (72.2%). The proportion of men not receiving mental health treatments of interest (47.7%) was similar compared to men without prostate cancer (49.1%), but statistically significantly lower compared to men with prostate cancer not receiving ADT (52.7%).

CONCLUSIONS

In men with prostate cancer receiving ADT with a new diagnosis of depression or anxiety, nearly half are not receiving mental health care while one in five is introduced to a benzodiazepine. Further investigation toward improving the mental health care for men on ADT is needed.

Dietary Fat and Prostate Cancer Relationship Using Trimmed Regression Under Uncertainty

In this paper, a new trimmed regression model under the neutrosophic environment is introduced. The mathematical model of the new regression model along with its neutrosophic form is given. The methods to find the error sum of square and trended values are also given. The trimmed neutrosophic correlation is also introduced in the paper. The proposed trimmed regression is applied to prostate cancer. From the analysis, it is concluded that the proposed model provides the minimum error sum of square as compared to the existing regression model under neutrosophic statistics. It is found that the proposed model is quite effective to forecast prostate cancer patients under an indeterminacy setting.

Psychological intervention to treat distress: An emerging frontier in cancer prevention and therapy

Psychological distress, such as chronic depression and anxiety, is a topical problem. In the context of cancer patients, prevalence rates of psychological distress are four-times higher than in the general population and often confer worse outcomes. In addition to evidence from epidemiological studies confirming the links between psychological distress and cancer progression, a growing body of cellular and molecular studies have also revealed the complex signaling networks which are modulated by psychological distress-derived chronic stress during cancer progression. In this review, aiming to uncover the intertwined networks of chronic stress-driven oncogenesis and progression, we summarize physiological stress response pathways, like the HPA, SNS, and MGB axes, that modulate the release of stress hormones with potential carcinogenic properties. Furthermore, we discuss in detail the mechanisms behind these chronic stimulations contributing to the initiation and progression of cancer through direct regulation of cancer hallmarks-related signaling or indirect promotion of cancer risk factors (including obesity, disordered circadian rhythms, and premature senescence), suggesting a novel research direction into cancer prevention and therapy on the basis of psychological interventions.

Self-reported lack of energy or feeling depressed 12 months after treatment in men diagnosed with prostate cancer within a population-based registry

OBJECTIVE

Feeling depressed and lethargic are common side effects of prostate cancer (PCa) and its treatments. We examined the incidence and severity of feeling depressed and lack of energy in patients in a population based PCa registry.

METHODS

We included men diagnosed with PCa between 2015 and 2019 in Victoria, Australia, and enrolled in the Prostate Cancer Outcomes Registry. The primary outcome measures were responses to two questions on the Expanded Prostate Cancer Index Composite (EPIC-26) patient reported instrument: problems with feeling depressed and problems with lack of energy 12 months following treatment. We evaluated associations between these and age, cancer risk category, treatment type, and urinary, bowel, and sexual function.

RESULTS

Both outcome questions were answered by 9712 out of 12,628 (77%) men. 981 patients (10%) reported at least moderate problems with feeling depressed; 1563 (16%) had at least moderate problems with lack of energy and 586 (6.0%) with both. Younger men reported feeling depressed more frequently than older men. Lack of energy was more common for treatments that included androgen deprivation therapy than not (moderate/big problems: 31% vs. 13%), irrespective of disease risk category. Both outcomes were associated with poorer urinary, bowel, and sexual functional domain scores.

CONCLUSIONS

Self-reported depressive feelings and lack of energy were frequent in this population-based registry. Problems with feeling depressed were more common in younger men and lack of energy more common in men having hormonal treatment. Clinicians should be aware of the incidence of these symptoms in these at-risk groups and be able to screen for them.

Association between Traditional Chinese medicine and a lower risk of dementia in patients with major depression: A case-control study

ETHNOPHARMACOLOGICAL RELEVANCE

Major depression is an important risk factor for dementia. Traditional Chinese medicine (TCM) can alleviate the symptoms of major depression. However, it is unclear whether TCM decreases the risk of dementia in patients with major depression. Therefore, in this nationwide case-control study, we aimed to evaluate the association between TCM and the risk of dementia.

MATERIALS AND METHODS

We included 31,981 major depression patients with dementia from the National Dementia Database as the case group, and 4391 major depression patients without dementia from a one-million random sample database as the control group. We matched age (plus or minus two years), sex, and year of depression diagnosis based on a 1:4 ratio.

RESULT

There were 11,724 and 2931 patients in the case and control groups, respectively. Based on a conditional logistic regression analysis, the TCM groups exhibited significantly lower odds ratios with a 95% confidence interval of 0.83 (0.74-0.91). TCM treatment for more than 90 days, dispersing Qi, and activating blood circulation resulted in lower dementia risk with the following odds ratios and 95% confidence intervals: 0.60 (0.56-0.68), 0.87 (0.74-1.08), and 0.66 (0.49-0.81).

CONCLUSION

The results suggest that TCM is associated with lower dementia risk in major depression patients.

Psychosocial Stress and Age Influence Depression and Anxiety-Related Behavior, Drive Tumor Inflammatory Cytokines and Accelerate Prostate Cancer Growth in Mice

Prostate cancer (PCa) prevalence is higher in older men and poorer coping with psychosocial stressors effect prognosis. Yet, interactions between age, stress and PCa progression are underexplored. Therefore, we characterized the effects of age and isolation combined with restraint (2 h/day) for 14 days post-tumor inoculation on behavior, tumor growth and host defense in the immunocompetent, orthotopic RM-9 murine PCa model. All mice were tumor inoculated. Isolation/restraint increased sympathetic and hypothalamic-pituitary-adrenal cortical activation, based on elevated serum 3-methoxy-4-hydroxyphenylglycol/norepinephrine ratios and corticosterone levels, respectively. Elevated zero maze testing revealed age-related differences in naïve C57Bl/6 mice, and increased anxiety-like behavior in tumor-bearing mice. In open field testing, old stressed mice were less active throughout the 30-min test than young non-stressed and stressed, and old non-stressed mice, suggesting greater anxiety in old stressed mice. Old (18 month) mice demonstrated more depression-like behavior than young mice with tail suspension testing, without effects of isolation/restraint stress. Old mice developed larger tumors, despite similar tumor expression of tumor vascular endothelial growth factor or transforming growth factor-beta1 across age. Tumor chemokine/cytokine expression, commonly prognostic for poorer outcomes, were uniquely age- and stress-dependent, underscoring the need for PCa research in old animals. Macrophages predominated in RM-9 tumors. Macrophages, and CD4⁺ and CD4⁺FoxP3⁺ T-cell tumor infiltration were greater in young mice than in old mice. Stress increased macrophage infiltration in old mice. Conversely, stress reduced intratumoral CD4⁺ and CD4⁺FoxP3⁺ T-cell numbers in young mice. CD8⁺ T-cell infiltration was similar across treatment groups. Our findings support that age- and psychological stress interacts to affect PCa outcomes by interfering with neural-immune mechanisms and affecting behavioral responses.

The prognostic impact of depression or depressive symptoms on patients with head and neck cancer: A systematic review and meta-analysis

BACKGROUND

This systematic review and meta-analysis sought to assess the extent to which pretreatment depression or depressive symptoms are related to prognosis in patients with head and neck cancer (HNC).

METHODS

Medline, EMbase, Scopus, and The Cochrane Library databases were searched. A meta-analysis was done to generate a forest plot and pooled hazard ratio (HR) with 95% CI for overall survival (OS). RevMan 5.3 and Meta Essentials were used for statistical analysis.

RESULTS

Based on seven studies involving 1743 patients, the results showed that HNC patients with pretreatment depression or depressive symptoms had worse OS than patients without depression or depressive symptoms, with an HR of 1.33, 95% CI 1.16-1.52, p = <0.0001. There is heterogeneity in the pooled summary effect (I²  = 80%, p < 0.0001).

CONCLUSIONS

Pretreatment depression or depressive symptoms may indicate worse OS in patients with HNC. The pooled analysis demonstrated a statistically significant effect. These results were limited by mild heterogeneity.

Anxiety, depression and urological cancer outcomes: A systematic review

PURPOSE

The interplay between physical and mental aspects of a cancer diagnosis are well recognised. However, little consensus exists on the impact of depression and anxiety on urological cancer outcomes. Therefore, this systematic review aimed to investigate the relationship between these conditions and functional or oncological outcomes in urological malignancy.

MATERIALS AND METHODS

A systematic search was conducted using PubMed, Embase, PsycINFO and Global Health databases up to June 2020. Studies evaluating the relationship of anxiety and depression disorders or symptoms on functional and mortality outcomes were included. Outcome measures included validated urinary, sexual, body image questionnaire scores and all-cause or disease-specific mortality.

RESULTS

Of 3,966 studies screened, 25 studies with a total of 175,047 urological cancer patients were included. Significant anxiety and depressive symptoms and disorders were found to impact functional outcomes in several cancer types. A consistent negative association existed for sexual function in prostate, testicular and penile cancer patients. Additionally, poorer urinary function scores were seen in prostate cancer, with increased body image issues in testicular and prostate cancer. Importantly, both overall and disease-specific mortality outcomes were poorer in bladder and prostate cancer patients.

CONCLUSIONS

Co-existing depression and anxiety appears to be negatively associated with functional and mortality outcomes in urological cancers. This appears especially evident in male cancers, including prostate and testicular cancer. Although not proving causation, these findings highlight the importance of considering mental wellbeing during follow-up for early recognition and treatment. However, current evidence remains heterogenous, with further studies required exploring patients at risk.

Post-Treatment Adverse Health Correlates among Prostate Cancer Survivors in a Sample of Men Residing in Atlantic Canada

BACKGROUND

Recent large population-based studies have shed light on an association between prostate cancer (PCa) survivorship and mental health, which emerged when the comparison group was either men without a history of cancer or those with any other type of cancer except prostate. Here we examine the role of surgery alone, compared to other types of treatment modalities in this association in a population-based sample of men with prostate or other types of cancer.

METHODS

A cross-sectional analysis was conducted on a subsample of 632 male participants aged 36-69 from the 2009-2015 survey cycle of the Atlantic PATH cohort study. The primary outcomes were the presence of mild, moderate or severe depression or anxiety indicators and were assessed using the seven-item generalized anxiety disorder (GAD-7) scale and the nine-item Patient Health Questionnaire (PHQ-9), respectively. The presence of a lifetime history of PCa or other form of cancer (except PCa) was the main predictor variable and was assessed in cancer treatment modality (surgery or other types of treatment modalities) stratified analyses. Covariates included age, marital status, household income, comorbidity, and survivorship time.

RESULTS

The presence of depression in this sample was prevalent among 17.7% of men, and of anxiety among 9.3% of men. Survivors who were treated with surgery for their PCa diagnosis had 7.55 statistically significantly higher odds of screening positive for current depression symptoms compared with those of other forms of cancer in controlled analyses. These differences were not observed for anxiety.

CONCLUSIONS

These findings emphasize the need for multidisciplinary survivorship care plans among PCa patients, especially those who undergo surgery. Targeted programming aimed at prioritizing and delivering comprehensive mental health support to PCa survivors early in the survivorship journey is justified.

Mood disorder and cancer onset: evidence from a population-based sample of Australian women

OBJECTIVE

The role of mood disorders in cancer onset is unclear. The aim of this study was to investigate the association between mood disorder and incident cancer in a population-based sample of women.

METHODS

Data were derived from women aged 28-94 years participating in the Geelong Osteoporosis Study. Mood disorder was identified via Clinical Interview (SCID-I/NP). Cancer data was obtained following linkage with the Victorian Cancer Registry. Demographic and lifestyle factors were self-reported. Nested case-control and retrospective study designs were utilized.

RESULTS

In the case-control study (n=807), mood disorder was documented for 18 of the 75 (9.3%) cancer cases and among 288 controls (24.0% vs. 39.3%, p = 0.009). Prior exposure to mood disorder was associated with reduced cancer incidence (OR 0.49, 95%CI 0.28-0.84); this was sustained following adjustment for confounders (ORadj 0.52, 95%CI 0.30-0.90). In the retrospective cohort study (n=655), among 154 women with a history of mood disorder at baseline, 13 (8.5%) developed incident cancer during follow-up, whereas among 501 women with no history of mood disorder, 54 (10.8%) developed incident cancer. Exposure to mood disorder was not associated with incident cancer over the follow-up period (HR 0.58, 95%CI 0.31-1.08, p = 0.09).

CONCLUSION

Mood disorder was associated with reduced odds of cancer onset. However, this finding was not supported in the retrospective cohort study. Larger studies able to investigate specific cancers and mood disorders as well as underlying mechanisms in both men and women are warranted.

Long-term depression incidence and associated mortality among African American and White prostate cancer survivors

BACKGROUND

Depression is common after a diagnosis of prostate cancer and may contribute to poor outcomes, particularly among African Americans. The authors assessed the incidence and management of depression and its impact on overall mortality among African American and White veterans with localized prostate cancer.

METHODS

The authors used the Veterans Health Administration Corporate Data Warehouse to identify 40,412 African American and non-Hispanic White men diagnosed with localized prostate cancer from 2001 to 2013. Patients were followed through 2019. Multivariable logistic regression was used to measure associations between race and incident depression, which were ascertained from administrative and depression screening data. Cox proportional hazards models were used to measure associations between incident depression and all-cause mortality, with race-by-depression interactions used to assess disparities.

RESULTS

Overall, 10,013 veterans (24.5%) were diagnosed with depression after a diagnosis of prostate cancer. Incident depression was associated with higher all-cause mortality (adjusted hazard ratio [aHR], 1.27; 95% confidence interval [CI], 1.23-1.32). African American veterans were more likely than White veterans to be diagnosed with depression (29.3% vs 23.2%; adjusted odds ratio [aOR], 1.15; 95% CI, 1.09-1.21). Among those with depression, African Americans were less likely to be prescribed an antidepressant (30.4% vs 31.7%; aOR, 0.85; 95% CI, 0.77-0.93). The hazard of all-cause mortality associated with depression was greater for African American veterans than White veterans (aHR, 1.32 [95% CI, 1.26-1.38] vs 1.15 [95% CI, 1.07-1.24]; race-by-depression interaction P < .001).

CONCLUSIONS

Incident depression is common among prostate cancer survivors and is associated with higher mortality, particularly among African American men. Patient-centered strategies to manage incident depression may be critical to reducing disparities in prostate cancer outcomes.

Breaking the patientification process - through co-creation of care, using old arctic survival knowledge

Purpose: Cancer research and connected innovation processes often lack a major component; patient participation. We revisit three studies (a-c) in order to explore how Momentary contentment theory may be used to improve patient participation and psychosocial health.

Method: We revisited data from the initial (a) classic grounded theory study on Momentary contentment, based on four years of observation and 14 interviews. It explains a way of dealing with life close to death and morbidity. In the imminence of danger the studied culture resembles the context of cancer patients. The two following studies used focus group interviews with (b) 19 cancer patients and (c) 17 relatives of cancer patients in southern Sweden.

Results: We suggest a process where cancer patients are taught to be submissive and that the support they receive from health providers may be counterproductive to contentment; a patientification process. We present alternative ways for people to handle issues such as hope, waiting, knowledge gaps and healthcare navigation while living with cancer. We introduce an alternative to patientification and passive patients where active patients create their own safety and truly participates in their care.Conclusions: We propose clinical studies to introduce such a shift from patentification to co-creation of care.

Novel Combinatorial Approaches to Tackle the Immunosuppressive Microenvironment of Prostate Cancer

Prostate cancer (PCa) is the second-most common cancer in men worldwide and treatment options for patients with advanced or aggressive prostate cancer or recurrent disease continue to be of limited success and are rarely curative. Despite immune checkpoint blockade (ICB) efficacy in some melanoma, lung, kidney and breast cancers, immunotherapy efforts have been remarkably unsuccessful in PCa. One hypothesis behind this lack of efficacy is the generation of a distinctly immunosuppressive prostate tumor microenvironment (TME) by regulatory T cells, MDSCs, and type 2 macrophages which have been implicated in a variety of pathological conditions including solid cancers. In PCa, Tregs and MDSCs are attracted to TME by low-grade chronic inflammatory signals, while tissue-resident type 2 macrophages are induced by cytokines such as IL4, IL10, IL13, transforming growth factor beta (TGFβ) or prostaglandin E2 (PGE2) produced by Th2 cells. These then drive tumor progression, therapy resistance and the generation of castration resistance, ultimately conferring a poor prognosis. The biology of MDSC and Treg is highly complex and the development, proliferation, maturation or function can each be pharmacologically mediated to counteract the immunosuppressive effects of these cells. Herein, we present a critical review of Treg, MDSC and M2 involvement in PCa progression but also investigate a newly recognized type of immune suppression induced by the chronic stimulation of the sympathetic adrenergic signaling pathway and propose targeted strategies to be used in a combinatorial modality with immunotherapy interventions such as ICB, Sipuleucel-T or antitumor vaccines for an enhanced anti-PCa tumor immune response. We conclude that a strategic sequence of therapeutic interventions in combination with additional holistic measures will be necessary to achieve maximum benefit for PCa patients.

Comorbid depression in surgical cancer patients associated with non-routine discharge and readmission

OBJECTIVE

To characterize the rates of depression across primary cancer sites, and determine the effects of comorbid depression among surgical cancer patients on established quality of care indicators, non-routine discharge and readmission.

METHODS

Patients undergoing surgical resection for cancer were selected from the Nationwide Readmissions Database (2010-2014). Multivariable analysis adjusted for patient and hospital level characteristics to ascertain the effect of depression on post-operative outcomes and 30-day readmission rates. Non-routine discharge encompasses discharge to skilled nursing, inpatient rehabilitation, and intermediate care facilities, as well as discharge home with home health services.

RESULTS

Among 851,606 surgically treated cancer patients, 8.1% had a comorbid diagnosis of depression at index admission (n = 69,174). Prevalence of depression was highest among patients with cancer of the brain (10.9%), female genital organs (10.9%), and lung (10.5%), and lowest among those with prostate cancer (4.9%). Depression prevalence among women (10.9%) was almost twice that of men (5.7%). Depression was associated with non-routine discharge after surgery (OR 1.20, CI:1.18-1.23, p < 0.0001*) and hospital readmission within 30 days (OR 1.12, CI:1.09-1.15, p < 0.001*).

CONCLUSION

Rates of depression vary amongst surgically treated cancer patients by primary tumor site. Comorbid depression in these patients is associated with increased likelihood of non-routine discharge and readmission.

Unlocking the Mystery of the Therapeutic Effects of Chinese Medicine on Cancer

Over the past decade, the rise of cancer immunotherapy has coincided with a remarkable breakthrough in cancer therapy, which attracted increased interests in public. The scientific community clearly showed that the emergence of immunotherapy is an inevitable outcome of a holistic approach for cancer treatment. It is well established that traditional Chinese medicine (TCM) utilizes the principle of homeostasis and balance to adjust the healthy status of body. TCM treatment toward cancer has a long history, and the diagnosis and treatment of tumors were discussed in the ancient and classical literatures of Chinese medicine, such as the Yellow Emperor’s Inner Canon. Precious heritage has laid the foundation for the innovation and development of cancer treatment with TCM. The modern study indicated that TCM facilitates the treatment of cancer and enhances the survival rate and life expectancy of patients. However, the pharmacological mechanisms underlying these effects are not yet completely understood. In addition, physicians cannot always explain why the TCM treatment is effective and the mechanism of action cannot be explained in scientific terms. Here, we attempted to provide insights into the development of TCM in the treatment and interpret how TCM practitioners treat cancer through six general principles of TCM by using modern scientific language and terms based on newly discovered evidence.

Mental distress and need for psychosocial support in prostate cancer patients: An observational cross-sectional study

OBJECTIVE

Prostate cancer is the most common cancer in German men and associated with various physical and psychosocial problems. This study investigated the association between mental distress and the subjective need for psychosocial support comparing subgroups of patients with different treatments and disease stages.

METHOD

We performed an observational, cross-sectional study including patients with four medical conditions: Active Surveillance, radical prostatectomy, biochemical relapse, metastasized disease. Mental distress (NCCN Distress-Thermometer), symptoms of depression and anxiety (PHQ-9, GAD-7), psychosocial needs and coping resources (self-designed questionnaire) were assessed.

RESULTS

N = 130 patients were included. 33.3% showed distress, 16.5% symptoms of moderate depression and 13% symptoms of moderate anxiety. We found no significant differences between the four groups. An association was present between distress and wish for psychosocial support (χ² = 4.3; p < 0.05; ϕ = 0.19). Almost 90% lived with a partner, which represents a resource.

CONCLUSIONS

Prostate cancer patients showed low levels of mental distress, depression and anxiety with no difference in terms of disease stage and treatment modality. Therefore, careful psychosocial screening of all patients is essential to identify those in need for support. Distressed patients express a need for psychosocial support more often. Interpersonal relationships, most often wives and children, represent important coping resources.

Patient preferences for treatment of advanced melanoma: impact of comorbidities

BACKGROUND AND OBJECTIVES

Choice of treatment for advanced melanoma is crucially influenced by comorbidities and patient preferences. Our study aimed to investigate the impact of comorbidities on preferences.

PATIENTS AND METHODS

150 patients with melanoma stage IIC-IV completed a discrete choice experiment to determine preferences for outcome (overall response rate [ORR], 2-year survival, progression-free survival [PFS], time to response [TTR], kind of adverse events [AE], AE-related treatment discontinuation) and process attributes (frequency and route of administration [RoA], frequency of consultations) of systemic melanoma treatments. The impact of comorbidities was assessed by analysis of variance and multivariate regression.

RESULTS

Participants with hypertension and other cardiovascular diseases attached significantly greater importance to TTR and RoA than others. Respondents with arthropathy cared more about TTR (β = 0.179, P = 0.047) and RoA, but less about ORR (β = -0.209, P =  0.021). Individuals with diabetes considered AE (β = 0.185, P = 0.039) and frequency of consultations more essential, but ORR less relevant. Those with other malignancies were particularly worried about treatment discontinuation (β = 0.219, P =  0.008), but less about ORR (β = -0.202, P =  0.015). Participants with depression focused more on PFS (β = 0.201, P =  0.025) and less on TTR (β = -0.201, P =  0.023) and RoA (β = -0.167, P =  0.050).

CONCLUSIONS

Treatment preferences of melanoma patients vary significantly dependent on comorbidities.

Retrospective Analyses of Psychological Distress and Defense Style Among Cancer Patients

OBJECTIVE

Psychological distress is common in cancer patients during the diagnostic phase. Research demonstrated that anxiety, depression and defense mechanisms may influence physical and psychological well-being in patients with malignant tumors. The present retrospective study investigated the associations between clinical and psychological characteristics of cancer patients waiting for the diagnosis, focusing on metastatic cancer (MC) and breast cancer (BC).

METHOD

Patients with a new diagnosis of cancer referring to a Clinical Oncology Unit in Central Italy were interviewed during the 2017 for psychological assessment. Double-blind information about anxiety, depression, sleep disorders, defense style, and cancer diagnosis were available for the 567 patients included in this study. T-test, chi-squared and regression analyses were performed to detect associations between psychological variables and the presence of metastasis (MC) in the whole sample and in the subgroup of breast cancer (BC) patients.

RESULTS

Female gender and younger age were associated with anxiety, depression, and maladaptive defense style. A significant positive relationship was found between presence of metastasis and symptoms of anxiety. Depression resulted significantly more frequent in BC, while there was a trend close to statistical significance in MC. Immature defense style was widely used by BC women, with a score close to statistical significance.

CONCLUSIONS

This retrospective study provided empirical evidence of the relationship between psychological functioning and clinical characteristics of cancer. In line with previous research, our findings confirmed the peculiar psychological functioning of BC patients. Further investigations are needed to understand how the diagnosis of cancer may influence the individual psychological functioning and vice versa.

Application of Neutrosophic Logic to Evaluate Correlation between Prostate Cancer Mortality and Dietary Fat Assumption

This paper presents an epidemiological study on the dietary fat that causes prostate cancer in an uncertainty environment. To study this relationship under the indeterminate environment, data from 30 countries are selected for the prostate cancer death rate and dietary fat level in the food. The neutrosophic correlation and regression line are fitted on the data. We note from the neutrosophic analysis that the prostate cancer death rate increases as the dietary fat level in the people increases. The neutrosophic regression coefficient also confirms this claim. From this study, we conclude that neutrosophic regression is a more effective model under uncertainty than the regression model under classical statistics. We also found a statistical correlation between dietary fat and prostate cancer risk.

Spirit-Quieting Traditional Chinese Medicine may Improve Survival in Prostate Cancer Patients with Depression

Depression is associated with higher mortality in prostate cancer. However, whether traditional Chinese medicine (TCM) for depression improves outcomes in patients with prostate cancer is unclear. This retrospective cohort study evaluated the association between TCM for depression and mortality in patients with prostate cancer. During the period 1998⁻2012, a total of 248 prostate cancer patients in Taiwan with depression were enrolled and divided into three groups: TCM for depression (n = 81, 32.7%), TCM for other purposes (n = 53, 21.3%), and no TCM (n = 114, 46.0%). During a median follow-up of 6.2 years, 12 (14.8%), 13 (24.5%), and 36 (31.6%) deaths occurred in the TCM for depression, TCM for other purposes, and no TCM groups, respectively. After adjusting age at diagnosis, urbanization, insured amount, comorbidity disease, and prostate cancer type, TCM for depression was associated with a significantly lower risk of overall mortality based on a multivariate-adjusted Cox proportional-hazards model (hazard ratio 0.42, 95% confidence interval: 0.21⁻0.85, p = 0.02) and Kaplan⁻Meier survival curve (log-rank test, p = 0.0055) compared to no TCM. In conclusion, TCM for depression may have a positive association with the survival of prostate cancer patients with depression.
