Dispositional optimism predicts survival status 1 year after diagnosis in head and neck cancer patients

The interplay of coping styles and optimism/pessimism in shaping mental health in long-term survivors of malignant melanoma: a register-based cohort study

BACKGROUND

Optimism and pessimism are stable, overarching dispositions that influence mental health, especially in stressful life situations, such as cancer survival. They have been associated with more specific coping strategies. This study sought to investigate a theoretically-based model of their interplay in shaping depressive and anxiety symptoms to inform prevention and intervention efforts.

METHODS

The registry-based study included 689 survivors of malignant melanoma. We assessed sociodemographic and disease-related variables, optimism/pessimism (LOT-R), coping strategies (BC), depressive (PHQ-9), and anxiety symptoms (GAD-7). A structural equation model was conducted to analyse the hypothesized associations, modelling coping strategies (denial/self-blame, seeking external support, active coping) as mediators of the relationship of optimism/pessimism with depressive and anxiety symptoms. As a sensitivity analysis, gender-stratified models were tested.

RESULTS

The proposed model fit the data well. In the full sample, optimism was directly related to depression and anxiety, and the effects of optimism and pessimism were mediated via denial/self-blame. This indirect effect accounted for 60.8% of the total effect of pessimism on depression, and for 79.55% on anxiety. Stratified analyses showed different patterns of associations by gender, in the sense that the mediation effect was more relevant among men.

CONCLUSION

This study shows the relevance and need of gender-sensitive psychosocial-care. Especially in men, psychosocial interventions should target maladaptive coping strategies. Within women, fostering optimism seems to be particularly important. As the model did not fit as well for women, more gender-sensitive research is needed to understand potentially different risk/protective factors and needs of support.

Mindfulness-based psychosocial interventions and psychological wellbeing in cancer survivorship: a meta-analysis

PURPOSE

Among cancer survivors, mindfulness-based interventions appear promising in decreasing distress for cancer patients, but little attention has been paid to the ultimate mindfulness goal of increasing psychological wellbeing. This meta-analysis aims to summarise and synthesise available evidence concerning the effectiveness of MBIs on positive psychological outcomes reflecting key aspects of psychological wellbeing in heterogeneous cancer patients.

METHODS

A literature search of mindfulness-based randomised clinical trials in cancer survivors was conducted across six electronic databases. Two reviewers independently screened studies and extracted data. Meta-analyses were conducted using R; standardised mean difference (SMD) was used to determine intervention effect. Moderators examined included therapeutic orientation, control group type, treatment modality, treatment target, heterogeneous vs. homogeneous cancer type, and facet of wellbeing.

RESULTS

Thirty-one studies were included (N = 2651). Those who received mindfulness-based interventions reported significantly higher eudaimonic, hedonic, and social wellbeing than respondents in control groups (SMD = 0.599). Interventions were equally effective across therapeutic orientation, control group type, treatment modality and treatment target. There were trend level differences favouring homogeneous cancer diagnosis groups over heterogeneous diagnosis groups.

CONCLUSION

MBIs provide an effective treatment for increasing psychological wellbeing in cancer survivors. This finding has important implications for clinical practice.

Research of correlation between personality traits and hormones with the nature of pulmonary nodules

Background

Rising rates of lung cancer screening have contributed to an increase in pulmonary nodule diagnosis rates. Studies have shown that psychosocial factors and hormones have an impact on the development of the oncological diseases. Therefore, we conducted this study to explore the potential relationship between pulmonary nodules pathology and patient personality traits and hormone levels.

Methods

This study enrolled 245 individuals who had first been diagnosed with pulmonary nodules in Tangdu Hospital and admitted for surgery. The personality profile of these patients was analyzed on admission using the C-Type Behavioral Scale and hormone levels were measured in preoperative serum samples. Associations between nodule pathology, personality scores, and hormone levels， were then assessed through Statistical methods analysis.

Results

Behavioral scale analyses revealed significant differences four items, including depression, anger outward, optimism, and social support (P< 0.05). Specifically, patients with higher depression scores were more likely to harbor malignant pulmonary nodules, as were patients with lower levels of anger outward, social support, and optimism. Univariate analyses indicated that nodule pathology was associated with significant differences in nodule imaging density, CT value, testosterone levels, and T4 levels(P< 0.05), and logistic regression analyses revealed pulmonary nodule imaging density and T4 levels to be significant differences of nodule pathology.

Conclusion

The results showed a significant association between nodules pathology and the personality characteristics of the patients (depression, anger outward, optimism, social support), the patients' T4 levels and the imaging density of the nodules.

Happy thus survivor? A systematic review and meta-analysis on the association between cancer survival and positive states, emotions, and traits

OBJECTIVES

Traditionally, the literature investigating patient-reported outcomes in relation to cancer survival focused on negative factors such as distress. Meta-analyses in this field have provided a clear identification of negative affect that reduce cancer survival (e.g., depression). Nevertheless, positive psychological factors and especially positive affect might be equally crucial for cancer survival but have been neglected so far. While studies in this domain have been conducted, they remain less numerous and have produced mixed results.

METHODS

A pre-registered systematic review and meta-analysis (https://osf.io/jtw7x) aimed at identifying the positive affect linked to mortality in cancers were conducted. Four databases (Pubmed, PsycINFO, Embase, and Cochrane Library) were searched to find longitudinal studies linking positive affect to survival in cancers. Two reviewers completed each stage of the study selection process, the data extraction, and the Quality in Prognosis Studies risk of bias assessments.

RESULTS

Twenty-four studies involving 822,789 patients were included based on the 2462 references identified. The meta-analysis reveals that positive affect is associated with longer survival (Hazard Ratio [HR] = 0.91; 95% CI [0.86, 0.96], z = -3.58, p < 0.001) and lower mortality (Odd Ratio [OR] = 0.59; 95% CI [0.45, 0.78], z = -3.70, p < 0.001). Sub-group analyses indicated that the main predictors of survival are emotional and physical well-being, optimism, and vitality.

CONCLUSION

This work emphasizes the need to consider the role of affective mechanisms in patients with cancer, including their levels of well-being or optimism to provide the most favorable conditions for survival. Therefore, stronger and continuous effort to improve patients' positive affect could be particularly beneficial for their life expectancy.

Implementing a cognitive behavioral intervention for patients with head and neck cancer

PURPOSE

Sequelae of and therapies for head and neck cancers (HNC) are associated with physical and functional impairment as well as increased levels of psychological distress post treatment. Given the impact of HNC and treatment on functioning (i.e., eating and talking), health-related quality of life (HRQOL) is a significant area of survivorship concern within this population. Although prior research indicates that the incidence of anxiety and depression ranges from 15 to 50%, to date, there is a paucity of research on specific psychosocial interventions related to HNC treatment and completed studies have been limited by infrequent use of a randomized design and provision of non-standardized psychosocial interventions. This study aimed to address these gaps and utilize a brief cognitive behavioral intervention (CBI) to improve (1) self-efficacy for coping with cancer, (2) depressive symptoms, (3) other psychological symptoms, and (4) HRQOL among patients with HNC.

METHODS

In an effort to conduct a randomized clinical trial of those undergoing treatment for HNC, eighty-eight patients were assigned to receive either a standardized CBI or usual psychological care (N = 47 and 41, respectively) with a 1-year follow-up. The means of all variables for both groups, adjusted for baseline, were visually compared at 3, 6, and 12 months post treatment.

RESULTS

As has been a challenge in other longitudinal HNC studies, a high degree of attrition occurred, with a loss of 35 patients from the CBI group and 29 from the usual care group. Despite the high attrition, analysis of existing data indicated that the effect of CBI was discernable among the patients who completed the course of the study. Of the 38 comparisons, 34 showed that the CBI group had the favorable outcome. Important considerations for implementation of a structured psychotherapy intervention during active cancer treatment with multiple barriers including communication challenges and practical limitations were realized.

CONCLUSIONS

The impact of HNC treatment can be particularly distressing as it often results in functional impairment and markedly changed activities of daily living among survivors. However, engaging in therapeutic methods to cope and manage distress during treatment can influence QOL and mood into the survivorship phase.

Environmental signals perceived by the brain abate pro-metastatic monocytes by dampening glucocorticoids receptor signaling

While positive social-behavioral factors predict longer survival in cancer patients, the underlying mechanisms are unknown. Since tumor metastasis are the major cancer mortality factor, we investigated how an enriched environment (EE) conductive to enhanced sensory, cognitive and motor stimulation impact metastatic progression in lungs following intravasation in the circulation. We find that mice housed in EE exhibited reduced number of lung metastatic foci compared to control mice housed in a standard environment (SE). Compared to SE mice, EE mice increased lung inflammation as early as 4 days after circulating tumor cells extravasation. The impact of environmental signals on lung metastasis is independent of adrenergic receptors signaling. By contrast, we find that serum corticosterone levels are lower in EE mice and that glucocorticoid receptor (GR) antagonist reduces the number of lung metastasis in SE mice. In addition, the difference of the number of lung metastasis between SE and EE mice is abolished when inflammatory monocytes are rendered deficient in GR signaling. This decreased GR signaling in inflammatory monocytes of SE mice results in an exacerbated inflammatory profile in the lung. Our study shows that not only EE reduces late stages of metastatic progression in lungs but disclose a novel anti-tumor mechanism whereby GR-dependent reprogramming of inflammatory monocytes can inhibit metastatic progression in lungs. Moreover, while inflammatory monocytes have been shown to promote cancer progression, they also have an anti-tumor effect, suggesting that their role is more complex than currently thought.

Posttraumatic Growth, Positive Psychology, Perceived Spousal Support, and Psychological Complications in Head and Neck Cancer: Evaluating Their Association in a Longitudinal Study

Despite head and neck cancer (HNC) association with various negative impacts, collective evidence is accumulating regarding the positive impacts of positive psychology on cancer survivors. However, data on how positive psychology is related to the psychological complications of HNC across time are lacking. This longitudinal study examined the trends of positive psychology (e.g., posttraumatic growth [PTG], hope, and optimism), perceived spousal support, and psychological complications (e.g., depression, anxiety, and posttraumatic stress symptoms) and determined the association between them, psychological complications, and PTG across two timelines among a cohort of HNC patients. A total of 175 HNC respondents exhibited an increasing trend of positive psychology and perceived spousal support while reporting a decreasing trend of psychological complications between baseline and follow-up assessments. A greater degree of hope and perceived spousal support contributed to a higher degree of PTG across time. Conversely, a higher severity of anxiety symptoms was associated with a lower degree of PTG over time. Female gender had a moderating effect on the association between severity of anxiety symptoms and PTG, but did not moderate the association between hope, perceived spousal support and PTG. This study indicates the pivotal role of incorporating psychosocial interventions into the treatment regimen to enhance the degree of hope and perceived spousal support and reduce the severity of anxiety symptoms, which, in turn, will facilitate the development of PTG in HNC patients.

The Correlation Between Quality of Life and Positive Psychological Resources in Cancer Patients: A Meta-Analysis

Purpose

This study aimed to assess the evidence of the association between positive psychological resources and quality of life in patients with cancer.

Methods

Electronic searching was performed to retrieve articles from PubMed, Web of Science, Embase, CNKI, and CBM (from inception to 7 April 2022). Summary correlation coefficient (r) values were extracted from each study, and 95% CIs were calculated by the random-effect model. Subgroup and sensitivity analyses were performed to investigate potential heterogeneity.

Results

In total, sixty-six articles were included in the present study. The pooled r for resilience was 0.71 (95%CI: 0.55, 0.87), hope 0.50 (95%CI: 0.43, 0.56), self-efficacy 0.53 (95%CI: 0.46, 0.61), self-esteem 0.46 (95%CI: 0.28, 0.63), and optimism 0.30 (95%CI: 0.19, 0.40). For subgroup analysis, no significant differences were found between minors and adults.

Conclusion

This study indicated that resilience, hope, optimism, self-esteem, and self-efficacy were positively correlated with quality of life in patients with cancers. Therefore, intervention programs should be focused on increasing state-like positive psychological resources to improve the quality of life in patients with cancer.

Acceptance and commitment therapy versus mindfulness-based stress reduction for newly diagnosed head and neck cancer patients: A randomized controlled trial assessing efficacy for positive psychology, depression, anxiety, and quality of life

Background and aim

Head and neck cancer patients are vulnerable to various psychological complications due to the effects of both cancer itself and cancer treatment on patients’ appearance and physical well-being. Nevertheless, few data have been obtained on effective psychosocial interventions that could protect this group of cancer patients’ psychological well-being. Therefore, this three-armed, parallel-group, double-blind, randomized control trial (RCT) aims to evaluate and compare the effects of acceptance and commitment therapy (ACT) and mindfulness-based stress reduction (MBSR) on positive psychology (such as posttraumatic growth [PTG], hope, and optimism), quality of life (QoL), and psychological complications (depression, anxiety, and experiential avoidance) among newly diagnosed head and neck cancer patients.

Methods and analysis

This RCT will target newly diagnosed head and neck cancer patients who have been treated only with surgery or who have not yet received any treatment. In total, 120 patients who meet all of the study’s inclusion criteria and none of its exclusion criteria will be randomly assigned into three groups—an ACT group, an MBSR group, and a treatment-as-usual control group—at a 1:1:1 allocation ratio. Participants in the two intervention groups (the ACT and MBSR groups) will undergo an eight-week group intervention program. During this program, each intervention will comprise eight modules based on ACT and MBSR, respectively. Outcome assessments will be performed across a three-point timeline, including before the intervention (t₀), immediately after the psychosocial intervention at eight weeks (t₁), and six months after the intervention (t₂). The primary outcome that will be assessed during this RCT is PTG. Meanwhile, the secondary outcomes that will be evaluated in this study are such as QoL, hope, optimism, depression, anxiety, and experiential avoidance.

The role of protective psychological factors, self-care behaviors, and HbA1c in young adults with type 1 diabetes

OBJECTIVE

To investigate whether protective psychological factors in young adults with type 1 diabetes are associated with more optimal self-care behaviors and HbA1c, and to explore possible mediators between protective psychological factors and HbA1c.

RESEARCH DESIGN AND METHODS

This cross-sectional study examined the associations between protective psychological factors (optimism, positive efficacy expectancies, and self-compassion), maladaptive psychological factors (depression, anxiety, and stress), self-care behaviors, and HbA1c in 113 young adults (17-25 years) with type 1 diabetes in Auckland, New Zealand. Pearson's correlations, multiple linear regressions, and multiple mediation analyses were used to examine associations and mediators.

RESULTS

Higher positive efficacy expectancies (beliefs about coping with difficulties) were associated with more optimal HbA1c (β = -0.26, 95% CI: -1.99 to -0.45) and more optimal self-care behaviors (β = 0.33, 95% CI: 0.28 to 0.92) in the adjusted models. Higher levels of self-compassion were associated with more optimal self-care behaviors (β = 0.27, 95% CI: 0.09 to 0.43). Depression was associated with less optimal self-care behaviors (β = -0.35, 95% CI: -1.33 to -0.43) and stress was associated with less optimal HbA1c (β = 0.26, 95% CI: 0.27 to 1.21). Mediation results suggested that self-care behaviors mediated the relationship between all three of the protective psychological factors and more optimal HbA1c, and that lower stress also mediated the relationship between higher self-compassion and more optimal HbA1c.

CONCLUSIONS

This study adds to the emerging literature that protective psychological factors may play an adaptive role in improving health outcomes in young adults with type 1 diabetes. Interventions targeting protective psychological factors present a promising approach to optimizing wellbeing and self-care in youth with type 1 diabetes.

The association of personality traits with poststroke fatigue in daily life: An exploratory experience sampling method and cross-sectional study

Fatigue is a frequently occurring and persistent symptom after stroke. Many biological, psychosocial, and behavioural factors are associated with poststroke fatigue, but research into associations with personality traits is relatively sparse. In this study, we explored whether personality traits were related to poststroke fatigue measured with conventional fatigue questionnaires as well as experience sampling methodology (ESM). Twenty-four individuals with stroke completed 10 daily questionnaires about momentary (here-and-now) fatigue for six consecutive days using the mHealth ESM application PsyMate^TM. Further, they completed questionnaires assessing personality (NEO-FFI and LOR-T) and fatigue (FSS). Results showed that higher extraversion (ß = -.44, SE = .12, p = .001; 95% CI = -.67-.19) and optimism (ß = -.18, SE = .06, p = .007; 95% CI = -.30-.05) were associated with lower momentary fatigue. No association was found between neuroticism and momentary fatigue, but higher neuroticism (r = 0.531, p = .008, 95% CI = .160-.759; r = .574, p = .003, 95% CI = .245-.767) was associated with higher scores on the retrospective FSS scales. We conclude that personality traits differentially influence poststroke fatigue, but this also depends on the way fatigue is measured (with retrospective or with momentary measures). When functional gains are not in line with expected progress during the rehabilitation treatment of fatigue, it may be appropriate to take into account how person characteristics are related to momentary fatigue.

Early Social Enrichment Modulates Tumor Progression and p53 Expression in Adult Mice

Epidemiological evidence indicates that stress and aversive psychological conditions can affect cancer progression, while well-being protects against it. Although a large set of studies have addressed the impact of stress on cancer, not much is known about the mechanisms that protect from cancer in healthy psychological conditions. C57BL/6J mouse pups were exposed to an environmental enrichment condition consisting of being raised until weaning by the biological lactating mother plus a non-lactating virgin female (LnL = Lactating and non-Lactating mothers). The Control group consisted of mice raised by a single lactating mother (L = Lactating). Four months after weaning, mice from LnL and L conditions were exposed to intramuscular injection of 3-methylcolantrene (3MCA), a potent tumorigenic drug, and onset and progression of 3MCA-induced fibrosarcomas were monitored over time. Pups from the LnL compared to the L group received more parental care and were more resilient to stressful events during the first week of life. In association, the onset of tumors in LnL adults was significantly delayed. At the molecular level, we observed increased levels of wild-type p53 protein in tumor samples of LnL compared to L adults and higher levels of its target p21 in healthy muscles of LnL mice compared to the L group, supporting the hypothesis of potential involvement of p53 in tumor development. Our study sustains the model that early life care protects against tumor susceptibility.

Dispositional optimism and all-cause mortality after esophageal cancer surgery: a nationwide population-based cohort study

PURPOSE

To examine the association between dispositional optimism and all-cause mortality after esophageal cancer surgery and whether pathological tumor stage and the COVID-19 pandemic modified this association.

METHODS

This nationwide, population-based prospective cohort study included 335 patients undergoing esophageal cancer surgery in Sweden between January 1, 2013, and December 31, 2019. Dispositional optimism was measured 1 year post-surgery using Life Orientation Test-Revised (LOT-R). A higher LOT-R sum score represents higher dispositional optimism. Mortality information was obtained from the Swedish Register of the Total Population. All patients were followed up until death or until December 31, 2020, whichever occurred first. Cox regression with adjustments for confounders was used.

RESULTS

The median follow-up was 20.8 months, during which 125 (37.3%) patients died. Among the included 335 patients, 219 (65.4%) patients had tumor pathologically staged Tis-II, and 300 (89.6%) patients entered the cohort before the COVID-19 pandemic. Both tumor stage and the COVID-19 pandemic were effect modifiers. For each unit increase in LOT-R sum score, the risk of all-cause mortality decreased by 11% (HR 0.89, 95% CI 0.81 to 0.98) among patients with tumor staged Tis-II before the COVID-19 pandemic. This association was non-significant in patients with tumor staged III-IV (HR 0.99, 95% CI 0.92 to 1.07) and during the COVID-19 pandemic (HR 1.08, 95% CI 0.94 to 1.25).

CONCLUSION

Assessing dispositional optimism may help predict postoperative survival, especially for patients with early and intermediate esophageal cancer. Increasing dispositional optimism might be a potential intervention target to improve survival after esophageal cancer surgery.

Cultural Determinants of Cancer Fatalism and Cancer Prevention Behaviors among Asians in Singapore

This research aims to better understand cultural disparities in cancer prevention behaviors. To do this, we investigate how four cultural beliefs - optimism, pessimism, naïve dialecticism, and superstition - associate with cancer fatalism, which has been recognized as a major barrier to cancer prevention behaviors. Based on an online survey of 1,021 Singapore residents, the results reveal that cancer fatalism is positively associated with pessimism, naïve dialecticism and superstitions, and associated negatively with optimism. Mediation analyses further reveal that cancer fatalism is a significant mediator between these four cultural beliefs and four cancer prevention behaviors including fruit and vegetable intake, regular exercise, avoidance of smoking, and sunscreen use. This study offers theoretical insights into the understanding of how people develop cancer fatalism and practical guidance on the promotion of cancer prevention behaviors, particularly among Asian populations.

Longitudinal changes in spiritual well-being and associations with emotional distress, pain, and optimism-pessimism: a prospective observational study of terminal cancer patients admitted to a palliative care unit

PURPOSE

Although spiritual well-being (SWB) is gaining increasing attention within the international palliative care (PC) guidelines, a lack of insight exists into the correlates and course of SWB among cancer patients. We therefore conducted a prospective observational study to capture trend of SWB and to identify their predictors in Chinese inpatients with terminal cancer receiving short-term PC.

METHODS

A prospective observational study was conducted of terminal cancer inpatients in the hospice ward, Shengjing Hospital of China Medical University. A total of 108 patients completed self-report questionnaires on Functional Assessment of Chronic Illness Therapy-Spiritual Well-being, Hospital Anxiety and Depression Scale, Numerical Rating Scales, and Life Orientation Scale-Revised anonymously at baseline; SWB, depression, anxiety, and pain were subsequently assessed at 1-week interval. Multilevel regression was used to analyze the temporal course and predictors of SWB.

RESULTS

Patients' existential well-being (B =  - 0.99, p = 0.008; 95%CI =  - 1.72 to - 0.26) and meaning dimension (B =  - 0.87, p < 0.001; 95% CI =  - 1.29 to - 0.43) significantly decreased after admission to the PC unit, but peace and faith did not change over time. Increases in depression and pain were related to lower existential well-being, particularly in the meaning dimension. Optimism-pessimism moderated the linear trend of existential well-being and meaning domain, such that those with higher optimism and lower pessimism paired with a decrease in outcomes.

CONCLUSIONS

Terminal cancer patients experienced worsening existential well-being, particularly in the meaning facet while hospitalized, indicating that PC should include content that targets the existential concerns of spirituality in China. These findings also supported the need for an integrated PC to address personality traits and emotional and physical distress in this population.

Systemic Regulation of Cancer Development by Neuro-Endocrine-Immune Signaling Network at Multiple Levels

The overarching view of current tumor therapies simplifies cancer to a cell-biology problem in which neoplasms are caused solely by malignant cells and the exploration of carcinogenesis and tumor progression largely focuses on somatic mutations and other genetic abnormalities of cancer cells. The limited therapeutic response indicates that cancer is driven not only by endogenous oncogenic factors and reciprocal interactions within the tumor microenvironment, but also by complex systemic processes. Homeostasis is the fundamental premise of health, and is maintained by systemic regulation of neuro-endocrine-immune axis. Cancer is also a systemic disease that manifested by dysfunction of the nervous, endocrine, and immune systems. Multiple axes of regulation exist in cancer, including central-, organ-, and microenvironment-level manipulation. At each specific regulatory level, the tridirectional communication among the nervous, endocrine, and immune factors transmit flexible signaling to induce proliferation, invasion, reprogrammed metabolism, therapeutic resistance, and other malignant phenotypes of cancer cells, resulting in the extremely poor prognosis of this lethal disease. Understanding this coordinated signaling network will enable the development of new approaches for cancer treatment via behavioral and pharmacological interventions.

Location as Destiny: Identifying Geospatial Disparities in Radiation Treatment Interruption by Neighborhood, Race, and Insurance

PURPOSE

Radiation therapy interruption (RTI) worsens cancer outcomes. Our purpose was to benchmark and map RTI across a region in the United States with known cancer outcome disparities.

METHODS AND MATERIALS

All radiation therapy (RT) treatments at our academic center were cataloged. Major RTI was defined as ≥5 unplanned RT appointment cancellations. Univariate and multivariable logistic and linear regression analyses identified associated factors. Major RTI was mapped by patient residence. A 2-sided P value <.0001 was considered statistically significant.

RESULTS

Between 2015 and 2017, a total of 3754 patients received RT, of whom 3744 were eligible for analysis: 962 patients (25.8%) had ≥2 RT interruptions and 337 patients (9%) had major RTI. Disparities in major RTI were seen across Medicaid versus commercial/Medicare insurance (22.5% vs 7.2%; P < .0001), low versus high predicted income (13.0% vs 5.9%; P < .0001), Black versus White race (12.0% vs 6.6%; P < .0001), and urban versus suburban treatment location (12.0% vs 6.3%; P < .0001). On multivariable analysis, increased odds of major RTI were seen for Medicaid patients (odds ratio [OR], 3.35; 95% confidence interval [CI], 2.25-5.00; P < .0001) versus those with commercial/Medicare insurance and for head and neck (OR, 3.74; 95% CI, 2.56-5.46; P < .0001), gynecologic (OR, 3.28; 95% CI, 2.09-5.15; P < .0001), and lung cancers (OR, 3.12; 95% CI, 1.96-4.97; P < .0001) compared with breast cancer. Major RTI was mapped to urban, majority Black, low-income neighborhoods and to rural, majority White, low-income regions.

CONCLUSIONS

Radiation treatment interruption disproportionately affects financially and socially vulnerable patient populations and maps to high-poverty neighborhoods. Geospatial mapping affords an opportunity to correlate RT access on a neighborhood level to inform potential intervention strategies.

Development of a Scale of Positive Temperament in Indian Context

BACKGROUND

Available tests of temperament measure the traits of different categories (like reward dependence, emotionality) with a large number of items. These tests do not deal specifically with traits of positive temperament (emotionality), and most scales measure negative emotionality as a counterpart of positive emotionality. The current study reports the development of a new scale of positive temperament, with fewer items and applicable in the Indian context.

METHODS

Items were developed with help from available scales of positive temperament, which led to the selection of 36 items from six different constructs. The data were collected in two stages for exploratory and confirmatory factor analysis of the scale. Stage one and two consisted of 278 and 338 participants, respectively, in the age group of 18-80 years, from both the genders and different professions. Data was collected online through the Qualtrics survey website. The participants responded on a 5-point Likert scale from 0-4 indicating how often they behave in a particular way as asked by the item. The test was reconducted on a subsample of 98 participants after 4 weeks to measure test-retest reliability. Convergent validity was also established using strengths and difficulties questionnaire and neuroticism scale, and divergent validity was found with age.

RESULTS

Exploratory factor analysis revealed four factors: optimism, perseverance, self-contentment, and adaptability. Confirmatory factor analysis later revealed that the 4-factor model fits best with the data, having comparative fit index (CFI) of 0.96 and root mean square error of approximation (RMSEA) of 0.063. The internal consistency estimates of the four factors ranged from 0.72 to 0.91, indicating a stable structure of scales. The final scale is of 28 items, with seven items in each factor. The test-retest reliability coefficients ranged from 0.79-0.96. Two second-order factors were also identified.

CONCLUSIONS

The positive temperament inventory is a four-factor, 28-item validated inventory with a stable set of items, having specific applicability in measuring positive temperament and fewer items for ease of use in different situations. This is the first scale of its kind in the Indian context and holds a promising future in the area of personality and clinical research.

Using Different Expectation Mechanisms to Optimize Treatment of Patients With Medical Conditions: A Systematic Review

OBJECTIVE

Patients' expectations have been shown to predict the course and treatment success of a variety of medical conditions. Therefore, expectation-focused psychological interventions (EFPIs) have been developed to use these expectation effects clinically. Importantly, EFPI differ with regard to the particular expectation mechanism being addressed, i.e., expectation optimization or expectation violation. The aims of this systematic review were to give an overview of the application of these expectation interventions and to evaluate their effectiveness.

METHODS

Several databases were searched to identify clinical trials or experimental studies that conducted EFPI among participants with various medical conditions. Risk of bias was evaluated using the Cochrane Risk of Bias tool.

RESULTS

Eleven studies (N = 944) investigating different medical conditions (coronary heart disease, cancer, chronic pain) were included. Qualitative synthesis revealed positive effects of EFPI on clinical outcome variables in all studies. Expectation optimization approaches yielded particularly promising results. Because of the large heterogeneity of outcome measures, quantitative synthesis was not possible.

CONCLUSION

This review highlights the potential of EFPI for optimizing treatment of patients with medical conditions. However, it seems that different expectation mechanisms might have different application possibilities. Therefore, we provide suggestions for further developing EFPI to tailor treatment and develop personalized psychological interventions. We argue that for this purpose, it is important to consider both disease-specific aspects and patients' personality traits. In addition, we discuss future challenges such as implementing EFPI into routine medical care.

The Mind-Body Study: study design and reproducibility and interrelationships of psychosocial factors in the Nurses' Health Study II

PURPOSE

Associations between psychosocial factors and biomarkers are increasingly investigated in studies of cancer incidence and mortality. Documenting optimal data/biospecimen collection protocols and scale properties are fundamental for elucidating the impact of psychosocial factors on biologic systems and ultimately cancer development/progression.

METHODS

Between 2013 and 2014, 233 Nurses' Health Study II women (mean age: 60.6) participated in the Mind-Body Study. Participants completed a detailed online psychosocial assessment and provided hair, toenail, timed saliva over 1 day, urine and fasting blood twice, 1 year apart. Additionally, two separate microbiome collections for stool and saliva were conducted between the psychosocial assessments. We assessed correlations between various psychosocial measures and evaluated their 1-year reproducibility using intraclass correlations (ICC).

RESULTS

Compliance with the protocols was high among participants. Psychosocial measures showed moderate-to-high reproducibility over 1 year (ICCs = 0.51-0.81). There was clear clustering of psychosocial factors according to whether they were querying positive (e.g., optimism, mastery, mindfulness) or negative (e.g., anxiety, depression, discrimination) emotion-related or social constructs.

CONCLUSION

Results suggest feasibility for self-administered collection of various biospecimens and moderate-to-high reproducibility of psychosocial factors. The Mind-Body Study provides a unique resource for assessing inter-relationships between psychosocial factors and biological processes linked with long-term health outcomes, including carcinogenesis.

Validation of the Korean Version of the McMaster Quality of Life Scale in Terminal Cancer Patients

The purpose of this study was to develop and validate a Korean version of McMaster Quality of Life Scale (K-MQLS) suitable for evaluating clinical hospice and palliative care. The McMaster Quality of Life Scale (MQLS) is a brief and comprehensive scale that is used to assess cancer patients receiving palliative care due to poor physical condition. To further develop the K-MQLS, we followed rigorous international translation steps and performed validity, reliability, and sensitivity analyses. The results of our study show that the K-MQLS is an efficient tool in terms of its validity, reliability, and sensitivity for the measurement of the health-related quality of life during the palliative phase. This developed tool could be used in research or clinical settings to assess health-related quality of life in Korean palliative care patients.

Resilience and Coping in Cancer Survivors: The Unique Effects of Optimism and Mastery

Optimism and mastery are two cognitive traits that involve positive expectations for the future and that have been demonstrated to be important predictors of reduced anxiety as well as superior coping and physical health in many populations, including cancer survivors. There is limited research, however, examining the unique effects of these traits when examined simultaneously. The present cross-sectional study used structural equation modeling to examine the unique effects of optimism and mastery on emotion, coping, and health in 603 adult cancer survivors, and whether results were consistent in men and women. Results indicated that both optimism and mastery were associated with improved emotion, coping, and health and together accounted for a small to moderate amount of variance. Although the effects of optimism were generally greater, mastery also uniquely predicted most dependent variables and there was some evidence that gender influenced these effects, with optimism predicting health control more so in women and mastery predicting health control more so in men. These results demonstrate that it is important to examine both generalized positive expectancies such as optimism and positive expectancies regarding mastery when investigating resilience and emotional well-being in cancer survivors.

Optimism and the conserved transcriptional response to adversity

Dispositional optimism, a personality trait predisposing individuals to positive expectations, has been suggested to promote better health. However, little is known about the biological mechanism of the salubrious health effects of optimism. We hypothesized that by diminishing a sense of threat to the self, optimism will be associated with a healthier profile of gene expression in immune cells. Specifically, the "conserved transcriptional response to adversity" (CTRA) is activated by fight-or-flight stress responses and results in increased transcription of genes involved in inflammation and decreased transcription of genes involved in antiviral defense. In a sample of 114 male Japanese workers, we found that optimism was inversely linked to CTRA after controlling for demographic variables, health-risk factors, and indices of well-being. These results are consistent with the hypothesis that reduced activity of threat-related gene expression programs may contribute to the health effects associated with optimism.

In Defense of "Denial": Difficulty Knowing When Beliefs Are Unrealistic and Whether Unrealistic Beliefs Are Bad

Bioethicists often draw sharp distinctions between hope and states like denial, self-deception, and unrealistic optimism. But what, exactly, is the difference between hope and its more suspect cousins? One common way of drawing the distinction focuses on accuracy of belief about the desired outcome: Hope, though perhaps sometimes misplaced, does not involve inaccuracy in the way that these other states do. Because inaccurate beliefs are thought to compromise informed decision making, bioethicists have considered these states to be ones where intervention is needed either to correct the person's mental state or to persuade the person to behave differently, or even to deny the person certain options (e.g., another round of chemotherapy). In this article, we argue that it is difficult to determine whether a patient is really in denial, self-deceived, or unrealistically optimistic. Moreover, even when we are confident that beliefs are unrealistic, they are not always as harmful as critics contend. As a result, we need to be more permissive in our approach to patients who we believe are unrealistically optimistic, in denial, or self-deceived-that is, unless patients significantly misunderstand their situation and thus make decisions that are clearly bad for them (especially in light of their own values and goals), we should not intervene by trying to change their mental states or persuade them to behave differently, or by paternalistically denying them certain options (e.g., a risky procedure).

Putting the life in lifestyle: Lifestyle choices after a diagnosis of cancer predicts overall survival

BACKGROUND

The aim of this study was to examine predictors of health behaviors over time and the link between health behaviors and survival after a diagnosis of advanced cancer.

METHODS

Patients with a diagnosis of advanced cancer were administered a battery of questionnaires measuring optimism, depressive symptoms, physical activity, intake of fruits and vegetables, and alcohol and tobacco use over an 18-month period. Analyses included generalized linear mixed models and Cox regression survival analyses.

RESULTS

Of the 334 patients enrolled in the study, the mean age at cancer diagnosis was 62 years; the majority were male (62.3%) and white (91%). Twenty percent of the patients reported using alcohol, 19% reported using tobacco, 19% reported eating fewer fruits and vegetables than recommended by the Centers for Disease Control and Prevention and 28% reported physical inactivity after the diagnosis of advanced cancer. Clinical levels of depressive symptoms were associated with lower intake of fruits and vegetables (t = 2.67, P = .007) and physical inactivity (t = 2.11, P = .035). Dispositional optimism was positively associated with physical activity (t = -2.16, P = .031) and a lower frequency of tobacco use (Z = -2.42, P = .015). Multivariate analyses revealed that after adjusting for demographic variables (age and sex), depressive symptoms, and disease-specific factors (diagnosis, tumor size, cirrhosis, vascular invasion, and number of lesions), alcohol use (χ²  = 4.1186, P = .042) and physical inactivity (χ²  = 5.6050, P = .018) were linked to an poorer survival.

CONCLUSIONS

Greater dissemination and implementation of effective interventions to reduce alcohol use and increase physical activity in cancer patients are recommended.

Big Five personality and health in adults with and without cancer

Personality is associated with health, but examinations in patients with illnesses are lacking. We aimed to determine whether personality-physical health associations differed between community and cancer samples. This cross-sectional study involved 168 participants without cancer, 212 men with prostate cancer, and 55 women with breast cancer. We examined whether the Big Five personality dimensions were associated with health behaviors and multiple health indicators. Higher conscientiousness and lower neuroticism were associated with better health behaviors and health (r_max = .31), with few differences between community and cancer samples. Findings call for research on the implications of personality in patients with serious illnesses.

The effects of pessimism on cell-mediated immunity in rats

We used a recently developed ambiguous-cue interpretation (ACI) paradigm to investigate whether 'optimism' and 'pessimism' as behavioural traits may be interrelated with immune functions in rodents. To this aim, in a series of ACI tests (cognitive bias screening, CBS), we identified rats that displayed 'pessimistic' and 'optimistic' traits. We found significant differences in immune biomarkers between 'optimistic' and 'pessimistic' animals. Moreover 'pessimism' was associated with significantly lower relative weight of the spleen and thymus, significantly decreased proliferative activity of splenocytes. Pessimism was associated with an increased production of interleukin-(IL)1β and IL-4, activin A, l-selectin, interferon (IFN)-γ and some chemokines and receptors for advanced glycation endproducts. The findings indicate an inflammatory profile in "pessimistic" animals.

Is spirituality related to survival in advanced cancer inpatients in Korea?

OBJECTIVE

Spirituality is what gives people meaning and purpose in life, and it has been recognized as a critical factor in patients' well-being, particularly at the ends of their lives. Studies have demonstrated relationships between spirituality and patient-reported outcomes such as quality of life and mental health. Although a number of studies have suggested that spiritual belief can be associated with mortality, the results are inconsistent. We aimed to determine whether spirituality was related to survival in advanced cancer inpatients in Korea.

METHOD

For this multicenter study, we recruited adult advanced cancer inpatients who had been admitted to seven palliative care units with estimated survival of &lt;3 months. We measured spirituality at admission using the Korean version of the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACIT-sp), which comprises two subscales: meaning/peace and faith. We calculated a Kaplan-Meier curve for spirituality, dichotomized at the predefined cutoffs and medians for the total scale and each of the two subscales, and performed univariate regression with a Cox proportional hazard model.ResultWe enrolled a total of 204 adults (mean age: 64.5 ± 13.0; 48.5% female) in the study. The most common primary cancer diagnoses were lung (21.6%), colorectal (18.6%), and liver/biliary tract (13.0%). Median survival was 19.5 days (95% confidence interval [CI95%]: 23.5, 30.6). Total FACIT-sp score was not related to survival time (hazard ratio [HR] = 0.981, CI95% = 0.957, 1.007), and neither were the scores for its two subscales, meaning/peace (HR = 0.969, CI95% = 0.932, 1.008) and faith (HR = 0.981, CI95% = 0.938, 1.026).Significance of resultsSpirituality was not related to survival in advanced cancer inpatients in Korea. Plausible mechanisms merit further investigation.

The impact of prostate cancer diagnosis and treatment decision-making on health-related quality of life before treatment onset

Objective

The objective of this study is to test if patients’ health-related quality of life (HRQoL) declines after prostate biopsy to detect Pca, and after subsequent treatment decision-making in case Pca is confirmed, and to test whether personality state and traits are associated with these potential changes in HRQoL.

Methods

Patients who were scheduled for prostate biopsy to detect Pca (N = 377) filled out a baseline questionnaire about HRQoL (EORTC QLQ-C30 and PR25), “big five” personality traits (BFI-10), optimism (LOT-r), and self-efficacy (Decision Self-efficacy Scale) (t0). Patients with confirmed Pca (N = 126) filled out a follow-up questionnaire on HRQoL within 2 weeks after treatment was chosen but had not yet started (t1).

Results

HRQoL declined between t0 and t1, reflected in impaired role and cognitive functioning, and elevated fatigue, constipation, and prostate-specific symptoms. Sexual activity and functioning improved. Baseline HRQoL scores were unrelated to the selection of a particular treatment, but for patients who chose a curative treatment, post-decision HRQoL showed a greater decline compared to patients who chose active surveillance. Optimism was associated with HRQoL at baseline; decisional self-efficacy was positively associated with HRQoL at follow-up. No associations between HRQoL and the “big five” personality traits were found.

Conclusion

Patients who have undergone prostate biopsy and treatment decision-making for Pca experience a decline in HRQoL. Choosing treatment with a curative intent was associated with greater decline in HRQoL. Interventions aimed at optimism and decision self-efficacy could be helpful to reduce HRQoL impairment around the time of prostate biopsy and treatment decision-making.

Family history of cancer and head and neck cancer survival

OBJECTIVE

Patients with a family history of cancer may be genetically predisposed to carcinogenesis. This could affect risk of recurrence, second primary tumors, and overall outcomes after treatment of a primary cancer. We evaluated the association between family history of cancer and disease-specific survival in a cohort of patients with primary head and neck squamous carcinoma (HNSCC).

STUDY DESIGN

Six hundred and forty-three incident HNSCC patients recruited through the University of Michigan Specialized Program of Research Excellence were followed for up to 5 years for survival. Participants were interviewed about personal and family cancer history, demographic information, and behavioral habits.

METHODS

Cox proportional hazards models were used to estimate the association between family history of cancer in a first-degree relative and disease-specific survival.

RESULTS

After multivariable adjustment, we found a nonsignificant inverse association between family history and HNSCC mortality (hazard ratio [HR] = 0.88, 95% confidence interval [CI] 0.57-1.35). This association was stronger and statistically significant among patients who currently both drank alcohol and smoked cigarettes at diagnosis (HR = 0.46, 95% CI = 0.22-0.97); no association was observed among participants who did not both drink and smoke at the time of diagnosis (HR = 1.14, 95% CI = 0.68-1.91; p-interaction = 0.046).

CONCLUSION

Results from this study suggest that having a family history of cancer may be associated with improved disease-specific survival in patients who use tobacco and alcohol. Additional large studies, particularly in populations including nonwhites and women, are needed to confirm or refute the association and to elucidate the genetic factors that may underlie this potential association.

Self-management strategies used by head and neck cancer survivors following completion of primary treatment: A directed content analysis

OBJECTIVE

Head and neck cancer (HNC) survivors encounter unique challenges following treatment. This study aimed to identify self-management strategies that HNC survivors use to overcome these posttreatment challenges.

METHODS

Twenty-seven individuals from 4 designated cancer centres in Ireland were interviewed about self-management strategies that helped them overcome challenges following HNC treatment. Interviews were audio-recorded, transcribed, and analysed using directed content analysis.

RESULTS

Twenty self-management strategy types (encompassing 77 specific strategies) were identified. The most frequently used self-management strategy types were self-sustaining (used by 26 survivors), self-motivating (n = 25), and proactive problem solving (n = 25). The most frequently used specific strategies were adaptive approaches to ongoing physical consequences of HNC and its treatment (n = 24), customising dietary practices (n = 24), and maintaining a positive outlook (n = 22).

CONCLUSIONS

The study identified strategies that helped HNC survivors to self-manage posttreatment challenges. This information could inform the design/development of self-management interventions tailored towards HNC survivors.

Oesophageal Adenocarcinoma: A Patient and Physician's Perspective

This article is co-authored by a patient with oesophageal adenocarcinoma and his physician, who performed oesophagectomy. The patient relates his pre-operative preparation and post-operative experience. The physician comments on the alarming increase in the incidence of this cancer, risk factors, and treatment. As illustrated by the patient's report, the physician also discusses the importance of maintaining adequate nutrition, cardiorespiratory fitness, and a positive psychological attitude.

Interruptions of Head and Neck Radiotherapy Across Insured and Indigent Patient Populations

Purpose:

Radiotherapy for head and neck cancer is a cornerstone of care, requiring 30 to 35 days of treatment over 6 to 7 weeks. Diligent patient compliance is crucial, and unplanned treatment interruptions reduce cure rates. We studied interruption rates in private carrier–insured and Medicare-insured populations versus indigent populations served by a single academic health system.

Materials and Methods:

A retrospective cohort study of electronic medical and billing records was performed analyzing treatment interruptions between January 2011 and December 2014. The study included 564 patients with head and neck cancer prescribed radiotherapy and referred from clinics run by University of Texas Southwestern Medical Center (UTSW) and the Parkland Health and Hospital System (PHHS), which provides indigent care to Dallas County, Texas.

Results:

Three-hundred sixteen patients (56%) had a treatment break; 114 patients missed a single session, and 202 patients missed multiple treatments. Seventy percent of PHHS patients had treatment delays compared with 47% of UTSW patients ( P < .001). The number of interrupted days in the PHHS population was nearly twice that observed in UTSW patients. PHHS patients most commonly missed treatment for nonmedical or logistical reasons. Delay was predictive for local recurrence ( P < .001) and overall survival ( P < .001). In compliant patients, there was no significant difference in local recurrence ( P = .43) or overall survival ( P = .27) across referral sites. However, among noncompliant patients, there was a higher likelihood for local recurrence in the PHHS cohort ( P = .016). Multivariable modeling suggested treatment interruption to be a key driver of outcome differences across referral sites.

Conclusion:

Survival outcomes in our at-risk population were inferior to those in patients insured by commercial carriers or Medicare. Treatment interruption predicted for poor outcome across all patients but was disproportionately experienced by at-risk patients. These results highlight cancer control needs specific to disadvantaged communities at risk for poor treatment compliance.

Motivation and mortality in older women with early stage breast cancer: A longitudinal study with ten years of follow-up

OBJECTIVES

The Getting Out of Bed Scale (GOB) was validated as a health-related quality of life (HRQoL) variable in older women with early stage breast cancer, suggesting its potential as a concise yet powerful measure of motivation. The aim of our project was to assess the association between GOB and mortality over 10years of follow-up.

MATERIALS AND METHODS

We studied 660 women ≥65-years old diagnosed with stage I-IIIA primary breast cancer. Data were collected over 10years of follow-up from interviews, medical records, and death indexes.

RESULTS

Compared to women with lower GOB scores, women with higher GOB had an unadjusted hazard ratio (HR) of all-cause mortality of 0.78 at 5years, 95% confidence interval (CI) (0.52, 1.19) and 0.77 at 10years, 95%CI (0.59, 1.00). These associations diminished after adjusting for age and stage of breast cancer, and further after adjusting for other HRQoL variables including physical function, mental health, emotional health, psychosocial function, and social support. Unadjusted HRs of breast cancer-specific mortality were 0.92, 95%CI (0.49, 1.74), at 5years, and 0.82, 95%CI (0.52, 1.32), at 10years. These associations also decreased in adjusted models.

CONCLUSION

Women with higher GOB scores had a lower hazard of all-cause mortality in unadjusted analysis. This effect diminished after adjusting for confounding clinical and HRQoL variables. GOB is a measure of motivation that may not be independently associated with cancer mortality, but reflects other HRQoL variables making it a potential outcome to monitor in older patients with cancer.

Optimism and Hope in Chronic Disease: A Systematic Review

There is a growing recognition that positive psychological functioning (which includes constructs such as optimism and hope) influences health. However, the understanding of these underlying mechanisms in relation to health is limited. Therefore, this review sought to identify what the scientific literature says about the influence of optimism and hope on chronic disease treatment. A search was conducted in the PsycINFO, Scopus, Pubmed, and Web of Science databases using the indexing terms optimism, hope, chronic diseases, randomized controlled trial, and treatment between 1998 and 2015. In the articles, we identified the most studied diseases in context, the assessment instruments used, the participant characteristics investigated, the results found, and the publication dates. From our analysis of the articles that met our inclusion criteria, it appears that the study of these constructs is recent and there is evidence that individuals with greater optimism and hope seek to engage in healthier behaviors, regardless of their clinical status, and that this contributes to chronic disease treatment. More research is needed so that targeted interventions can be carried out effectively in chronic disease treatment.

The Impact of Hope and Resilience on Multiple Factors in Neurosurgical Patients

The purpose of the present article is to outline and review the impact of stable psychological characteristics on the emotional and functional outcomes of neurosurgical patients. Neurosurgical patients face adversity as inherent to their diagnoses and, consequently, experience emotional distress. Despite commonalities in diagnoses, diverse outcomes are seen post-neurosurgery, which are influenced by psychological factors. Therefore, an understanding of neurosurgical patients’ behavior, thoughts, and feelings surrounding their diagnoses, informed by psychological concepts, is important for both neuropsychology and neurosurgery.

Optimism and Mortality in Older Men and Women: The Rancho Bernardo Study

Purpose. To examine the associations of optimism and pessimism with all-cause, cardiovascular disease (CVD), coronary heart disease (CHD), and cancer mortality in a population-based sample of older men and women followed ≤12 years. Methods. 367 men and 509 women aged ≥50 from the Rancho Bernardo Study attended a 1999-2002 research clinic visit when demographic, behavioral, and medical history were obtained and completed a 1999 mailed survey including the Life Orientation Test-Revised (LOT-R). Mortality outcomes were followed through 2012. Results. Average age at baseline was 74.1 years; during follow-up (mean = 8.1 years), 198 participants died, 62 from CVD, 22 from CHD, and 49 from cancer. Total LOT-R, optimism and pessimism scores were calculated. Participants with the highest optimism were younger and reported less alcohol use and smoking and more exercise. Cox proportional hazard models showed that higher total LOT-R and optimism, but not pessimism scores, were associated with reduced odds of CHD mortality after adjusting for age, sex, alcohol, smoking, obesity, physical exercise, and medication (HR = 0.86, 95% CI = 0.75, 0.99; HR = 0.77, 95% CI = 0.61, 0.99, resp.). No associations were found for all-cause, CVD, or cancer mortality. Conclusions. Optimism was associated with reduced CHD mortality in older men and women. The association of positive attitudes with mortality merits further study.

The Influence of Serum Cortisol Level Onto Perceptive Experience of Optimism in Patients with Newly Diagnosed Cancer

THE AIM

The aim of this study is to investigate the correlation between the morning level of serum cortisol and perceptive experience of optimism in a selected group of 60 patients with newly diagnosed cancer who were treated at Mostar University Clinical Hospital during a one-month period.

PATIENTS AND METHODS

The morning level of serum cortisol was measured in all patients following the verification of oncological disease. The patients also filled out a questionnaire of socio-demographic data, as well as the scales for optimism/pessimism assessment.

RESULTS

The average morning serum cortisol level was within the reference values in the majority of patients, independently of their perceptive experience of optimism/pessimism. There was no significant difference in the morning level of serum cortisol among the subgroups of patients high and low on the scale of optimism, as well as the scale of pessimism. No correlation existed between the serum cortisol morning level and expressed optimism/pessimism, as well. The great majority of respondents had secondary and lower education, was retired or unemployed, and suffered lower socio-economic conditions of life. Therefore, their access to medical information and their knowledge of cancer modern treatment options and possibilities were restricted, what may also have an influence onto perceptive experience of optimism/pessimism.

CONCLUSION

The results concerned with the perceptive experience of optimism/pessimism assessment were not a consequence of stress reaction but they were more correlated to general personal characteristics, the level of education, and socio-economic status of patients. The results do not confirm the impact of morning serum cortisol level onto physiological reactions to stressful conditions and situations in selected group of patients with de novo carcinoma.

Depression and Oropharynx Cancer Outcome

BACKGROUND

Studies have shown a modest relationship between depression and mortality in patients with cancer. Our study addressed methodological weaknesses in the literature by restricting the sample to patients with one cancer type, adjusting for factors known to affect outcome, and following up patients for a sufficient period.

METHODS

We prospectively followed patients newly diagnosed with squamous cell oropharyngeal cancer from the start of radiation therapy until death or until date of last clinical visit. All patients were optimally treated with radiation and sometimes chemotherapy. After adjusting for tumor stage, treatment, comorbidities, smoking, excessive alcohol use, and demographic factors, we assessed the effects of baseline self-reported depression on overall survival and recurrence.

RESULTS

One hundred thirty participants were followed for a median of 5 years. The average age was 56 years, and 83% were male. Eighteen participants died during the study and 15 experienced disease recurrence. Self-reported depression was associated with decreased overall survival duration (hazard ratio = 3.6, 95% confidence interval = 1.2-10.8) and disease recurrence (hazard ratio = 3.8, 95% confidence interval = 1.2-12.2) in multivariate analysis. In addition, smoking was associated with disease recurrence.

CONCLUSIONS

Patients with oropharyngeal cancer may benefit from depression screening and evidence-based treatments, if appropriate. Future studies are needed to determine whether depression is an independent prognostic factor of outcome and to elucidate biobehavioral mechanisms involved in patients with oropharyngeal cancer.

Hope, optimism and survival in a randomised trial of chemotherapy for metastatic colorectal cancer

PURPOSE

Psychological responses to cancer are widely believed to affect survival. We investigated associations between hope, optimism, anxiety, depression, health utility and survival in patients starting first-line chemotherapy for metastatic colorectal cancer.

METHODS

Four hundred twenty-nine subjects with metastatic colorectal cancer in a randomised controlled trial of chemotherapy completed baseline questionnaires assessing the following: hopefulness, optimism, anxiety and depression and health utility. Hazard ratios (HRs) and P values were calculated with Cox models for overall survival (OS) and progression-free survival (PFS) in univariable and multivariable analyses.

RESULTS

Median follow-up was 31 months. Univariable analyses showed that OS was associated negatively with depression (HR 2.04, P < 0.001) and positively with health utility (HR 0.56, P < 0.001) and hopefulness (HR 0.75, P = 0.013). In multivariable analysis, OS was also associated negatively with depression (HR 1.72, P < 0.001) and positively with health utility (HR 0.73, P = 0.014), but not with optimism, anxiety or hopefulness. PFS was not associated with hope, optimism, anxiety or depression in any analyses.

CONCLUSIONS

Depression and health utility, but not optimism, hope or anxiety, were associated with survival after controlling for known prognostic factors in patients with advanced colorectal cancer. Further research is required to understand the nature of the relationship between depression and survival. If a causal mechanism is identified, this may lead to interventional possibilities.

Hope in Severe Disease: A Review of the Literature on the Construct and the Tools for Assessing Hope in the Psycho-oncologic Setting

Aims and background

Research on the topic of hope began a long time ago but, more recently, interest in this construct has focused mainly on the development of psychometric tools for its assessment. The 2 steps of the present article are defining the construct of hope by completing a preliminary review of the literature and analyzing the tools used to assess hope in the setting of oncologic medicine, conducting a systematic review of the existing scientific literature.

Methods and Study Design

Our study was conducted in 2 stages. The first stage involved a nonsystematic preliminary review of the literature, the second a systematic search in all the medical journals contained in the Medline database as of 2012. The literature identified at the first stage was divided according to several topical categories, i.e., theoretical, empirical, and clinical works on the construct of hope. In the second systematic search, we identified the main psychometric tools used to measure hope in the field of clinical oncology and assessed their validity.

Results

A total of 22 articles were identified. What emerged when we pooled the findings of our 2 lines of research was that, despite its broad theoretical definitions, the construct of hope can be broken down to a few constituent elements when hope is studied using currently available psychometric tools. In particular, these identified constituent elements were coping, spiritual well-being, quality of life, distress, and depression.

Conclusions

The factors contained in the construct of hope include temporality, future, expectancy, motivation, and interconnectedness. The review of the scientific literature does not reveal a clear definition of hope. Multidisciplinary studies are needed to communicate different perspectives (medical, psychological, spiritual, theological) among each other for better definition of the constituent elements of hope in order to support the hope with specific interventions.

Can’t We Make It Any Shorter?

Psychological constructs are becoming increasingly important in social surveys. Scales for the assessment of these constructs are usually developed primarily for individual assessment and decision-making. Hence, in order to guarantee high levels of reliability, measurement precision, and validity, these scales are in most cases much too long to be applied in surveys. Such settings call for extremely short measures validated for the population as a whole. However, despite the unquestionable demand, appropriate measures are still lacking. There are several reasons for this. In particular, short scales have often been criticized for their potential psychometric shortcomings with regard to reliability and validity. In this article, the authors discuss the advantages of short scales as alternative measures in large-scale surveys. Possible reasons for the assumed limited psychometric qualities of short scales will be highlighted. The authors show that commonly used reliability estimators are not always appropriate for judging the quality of scales with a minimal number of items, and they offer recommendations for alternative estimation methods and suggestions for the construction of a thorough short scale.

Psychosocial functioning and vascular endothelial growth factor in patients with head and neck cancer

BACKGROUND

Psychosocial functioning is associated with vascular endothelial growth factor (VEGF) in various patient populations. This study examined whether psychosocial functioning in patients with head and neck squamous cell carcinoma (HNSCC) is associated with tumor VEGF expression, a protein that stimulates angiogenesis and is associated with poor prognosis.

METHODS

Forty-two newly diagnosed patients completed assessments of psychosocial functioning (ie, depressive symptoms, perceived stress, anxiety, social support) before surgery. Tumor samples were obtained for VEGF analysis and human papillomavirus (HPV)-typing.

RESULTS

Poorer psychosocial functioning was associated with greater VEGF expression controlling for disease stage (odds ratio [OR], 4.55; 95% confidence interval [CI], 1.72-12.0; p < .01). When examined by HPV status, the association between psychosocial functioning and VEGF remained significant among patients who were HPV negative (OR, 5.50; 95% CI, 1.68-17.3; p < .01), but not among patients who were HPV positive.

CONCLUSION

These findings inform our understanding of the biobehavioral pathways that may contribute to poor outcomes in non-HPV-associated HNSCCs.
