Yin and Yang of Psychological Health in the Cancer Experience: Does Positive Psychology Have a Role?

A Positive Psychology Intervention for Caregivers of Hematopoietic Stem Cell Transplantation Survivors (PATH-C): Initial Testing and Single-Arm Pilot Trial

Caregivers of patients with hematologic malignancies undergoing allogeneic hematopoietic stem cell transplantation (HSCT) play a crucial role in supporting their loved ones through physical, emotional, and practical challenges. This role has been associated with high levels of psychological distress and low levels of positive psychological well-being (PPWB). Positive psychology interventions for caregivers in other disease groups (eg, breast cancer) have been associated with improved outcomes. However, positive psychology interventions that specifically address HSCT caregivers' psychological needs are currently lacking. The goal of this single-arm open-pilot trial was to determine the feasibility and acceptability of the Positive Affect in the Transplantation of Hematopoietic Stem Cells (PATH) intervention for HSCT Caregivers to identify caregiver preferences to tailor PATH for HSCT caregivers. Adult caregivers of HSCT recipients were eligible for PATH during the HSCT recipient's first 100 d post-transplant. We defined, a priori, feasibility as >60% of participants who start the intervention completing ≥6/9 intervention sessions and acceptability as weekly ratings of ease and utility of the PP exercises ≥7/10 on a 10-point Likert Scale (0 = very difficult/not helpful; 10 = very easy/very helpful). We conducted semistructured qualitative exit interviews (n = 15) to explore HSCT caregivers' perception of PATH's content, benefits of PATH, as well as facilitators and barriers to engaging with the intervention. Transcribed interviews were analyzed using framework-guided rapid analysis by 2 coders. The intervention was feasible with 83% (15/18) of caregivers who started the intervention completing ≥6/9 intervention sessions. Among caregivers who completed ≥6/9 intervention sessions, ratings of ease (mean = 8.1; 95% CI: 7.4, 8.7) and utility (mean = 8.3; 95% CI: 7.8, 8.9) also exceeded our a priori threshold of ≥7/10. Caregivers identified benefits of PATH, including identifying and responding to emotions, dedicating time to self-care, and cultivating important relationships. Sociodemographic factors (eg, being retired) and the manualized structure of PATH were cited as facilitators to intervention engagement. Barriers to PATH engagement included lack of time and competing caregiving responsibilities. Caregivers preferred remote intervention delivery within the first 100 d post HSCT. This is the first study to show a 9-wk, phone-delivered positive psychology intervention is feasible in caregivers of allogeneic HSCT recipients. Our findings also underscore the specific preferences of this population for positive psychology interventions. Larger studies are warranted to establish the efficacy of these interventions in addressing persistent unmet psychological needs for HSCT caregivers.

"Pathways": A hope-enhancing intervention for patients undergoing treatment for advanced lung cancer

OBJECTIVE

Observational data suggest hope is associated with the quality of life and survival of people with cancer. This trial examined the feasibility, acceptability, and preliminary outcomes of "Pathways," a hope intervention for people in treatment for advanced lung cancer.

METHODS

Between 2020 and 2022, we conducted a single-arm trial of Pathways among participants who were 3-12 weeks into systemic treatment. Pathways consisted of two individual sessions delivered during infusions and three phone calls in which participants discussed their values, goals, and goal strategies with a nurse or occupational therapist. Participants completed standardized measures of hope and goal interference pre- and post-intervention. Feasibility was defined as ≥60% of eligible patients enrolling, ≥70% of participants completing three or more sessions, ≥70% of participants completing post-assessments, and mean acceptability ratings ≥7 out of 10 on intervention relevance, helpfulness, and convenience. Linear regression fixed effects models with covariates modeled pre-post changes in complete case analysis and multiple imputation models.

RESULTS

Fifty two participants enrolled: female (59.6%), non-Hispanic White (84.6%), rural (75.0%), and with low educational attainment (51.9% high school degree or less). Except for enrollment (54%), feasibility and acceptability markers were surpassed (77% adherence, 77% retention, acceptability ratings ≥8/10). There was moderate improvement in hope and goal interference from pre-to post-intervention (d = 0.51, p < 0.05 for hope; d = -0.70, p < 0.005 for goal interference).

CONCLUSIONS

Strong feasibility, acceptability, and patient-reported outcome data suggest Pathways is a promising intervention to increase hope and reduce cancer-related goal interference during advanced lung cancer treatment.

Gratitude, optimism, and satisfaction with life and patient-reported outcomes in patients undergoing hematopoietic stem cell transplantation

OBJECTIVE

Associations between positive psychological well-being (PPWB) and patient-reported outcomes (PROs, e.g., quality of life [QOL]) have yet to be studied extensively in patients with hematologic malignancies who are allogeneic hematopoietic stem cell transplant (HSCT) survivors, despite substantial evidence that PPWB impacts PROs of other medical populations.

METHODS

We conducted a secondary analysis of cross-sectional data examining the association of PPWB and PROs at day 100 post-transplant among 158 allogeneic HSCT recipients. Optimism, gratitude, life satisfaction, and PROs (i.e., QOL, anxiety, depression, and PTSD symptoms) were assessed using the Life Orientation Test-Revised, Gratitude Questionnaire, Satisfaction with Life Scale, Functional Assessment of Cancer Therapy-Bone Marrow Transplant, Hospital Anxiety and Depression Scale, and Post-Traumatic Stress Disorder (PTSD) Checklist-Civilian Version, respectively. We used linear and multivariate regressions for all analyses and controlled for patient factors.

RESULTS

Optimism was associated with better QOL (β = 1.46; p < 0.001) and lower levels of anxiety (β = -0.28; p < 0.001), depression (β = -0.31; p < 0.001), and PTSD (β = -0.58; p < 0.001). Gratitude was associated with better QOL (β = 1.11; p < 0.001) and lower levels of anxiety (β = -0.21; p = 0.001), depression (β = -0.14; p = 0.021), and PTSD (β = -0.32; p = 0.032). Finally, satisfaction with life was associated with better QOL (β = 1.26; p < 0.001) and lower levels of anxiety (β = -0.18; p < 0.001), depression (β = -0.21; p < 0.001), and PTSD (β = -0.49; p < 0.001).

CONCLUSION

Optimism, gratitude, and satisfaction with life were all associated with better QOL and lower levels of psychological distress in allogeneic HSCT survivors. These data support studies to harness PPWB as a therapeutic intervention for this population throughout HSCT recovery.

Positive Psychological Well-Being in Early Palliative Care: A Narrative Review of the Roles of Hope, Gratitude, and Death Acceptance

In the advanced cancer setting, low psychological functioning is a common symptom and its deleterious impact on health outcomes is well established. Yet, the beneficial role of positive psychological well-being (PPWB) on several clinical conditions has been demonstrated. Early palliative care (EPC) is a recent value-based model consisting of the early integration of palliative care into standard care for solid tumors and hematologic malignancies. While the late palliative care primary offers short-term interventions, predominantly pharmacological in nature and limited to physical symptom reduction, EPC has the potential to act over a longer term, enabling specific interventions aimed at promoting PPWB. This narrative review examines nine English studies retrieved from MEDLINE/PubMed, published up to October 2023, focusing on EPC and three dimensions of PPWB: hope, gratitude, and death acceptance. These dimensions consistently emerge in our clinical experience within the EPC setting for advanced cancer patients and appear to contribute to its clinical efficacy. The choice of a narrative review reflects the novelty of the topic, the limited existing research, and the need to incorporate a variety of methodological approaches for a comprehensive exploration.

Environment factors, DNA methylation, and cancer

Today, the rapid development of science and technology and the rapid change in economy and society are changing the way of life of human beings and affecting the natural, living, working, and internal environment on which human beings depend. At the same time, the global incidence of cancer has increased significantly yearly, and cancer has become the number one killer that threatens human health. Studies have shown that diet, living habits, residential environment, mental and psychological factors, intestinal flora, genetics, social factors, and viral and non-viral infections are closely related to human cancer. However, the molecular mechanisms of the environment and cancer development remain to be further explored. In recent years, DNA methylation has become a key hub and bridge for environmental and cancer research. Some environmental factors can alter the hyper/hypomethylation of human cancer suppressor gene promoters, proto-oncogene promoters, and the whole genome, causing low/high expression or gene mutation of related genes, thereby exerting oncogenic or anticancer effects. It is expected to develop early warning markers of cancer environment based on DNA methylation, thereby providing new methods for early detection of cancers, diagnosis, and targeted therapy. This review systematically expounds on the internal mechanism of environmental factors affecting cancer by changing DNA methylation, aiming to help establish the concept of cancer prevention and improve people's health.

Positive Psychological Well-Being in Hematopoietic Stem Cell Transplantation Survivors

Positive thoughts and emotions contribute to overall psychological health in diverse medical populations, including patients undergoing HSCT. However, few studies have described positive psychological well-being (eg, optimism, gratitude, flourishing) in patients undergoing HSCT using well-established, validated patient-reported outcome measures. We conducted cross-sectional secondary analyses of baseline data in 156 patients at 100 days post-HSCT enrolled in a randomized controlled trial of a psychological intervention (ClinicalTrials.gov identifier NCT05147311) and a prospective study assessing medication adherence at a tertiary care academic cancer center from September 2021 to December 2022. We used descriptive statistics to outline participant reports of positive psychological well-being (PPWB) using validated measures for optimism, gratitude, positive affect, life satisfaction, and flourishing. The participants had a mean age of 57.4 ± 13.1 years, and 51% were male (n = 79). Many, but not all, participants reported high levels of PPWB (ie, optimism, gratitude, positive affect, life satisfaction, and flourishing), defined as agreement with items on a given PPWB measure. For example, for optimism, 29% of participants did not agree that "overall, I expect more good things to happen to me than bad." Aside from life satisfaction, mean PPWB scores were higher in the HSCT population than in other illness populations. Although many patients with hematologic malignancies undergoing HSCT report high levels of PPWB, a substantial minority of patients reported low PPWB (i.e., no agreement with items on a given PPWB measure). Because PPWB is associated with important clinical outcomes in medical populations, further research should determine whether an intervention to promote PPWB can improve quality of life in HSCT recipients.

Feasibility of a positive psychology intervention (PATH) in allogeneic hematopoietic stem cell transplantation survivors: Randomized pilot trial design and methods

BACKGROUND

Although patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) experience low levels of positive psychological well-being (PPWB), interventions that specifically boost PPWB in this population are lacking.

OBJECTIVE

To describe the methods of a randomized controlled trial (RCT) designed to assess the feasibility, acceptability, and preliminary efficacy of a positive psychology intervention (PATH) tailored to the unique needs of HSCT survivors and aimed to decrease anxiety and depression symptoms and boost quality of life (QOL).

METHODS

We will conduct a single-institution RCT of a novel nine-week phone-delivered manualized positive psychology intervention compared to usual transplant care in 70 HSCT survivors. Allogeneic HSCT survivors at 100 days post-HSCT are eligible for the study. The PATH intervention, tailored to the needs of HSCT survivors in the acute recovery phase, focuses on gratitude, strengths, and meaning. Our primary aims are to determine feasibility (e.g., session completion, rate of recruitment) and acceptability (e.g., weekly session ratings). Our secondary aim is to test the preliminary efficacy of the intervention on patient-reported outcomes (e.g., anxiety symptoms, QOL).

DISCUSSION

If the PATH intervention is feasible, a larger randomized, controlled efficacy trial will be indicated. Additionally, we anticipate that the results from this RCT will guide the development of other clinical trials and larger efficacy studies of positive psychology interventions in vulnerable oncological populations beyond HSCT.

Early palliative care for solid and blood cancer patients and caregivers: Quantitative and qualitative results of a long-term experience as a case of value-based medicine

Introduction

Cancer patients and their caregivers have substantial unmet needs, that negatively impact the clinical outcome and quality of life. However, interventions aimed to address such needs are still suboptimal, failing to answer the recent healthcare call for the adoption of value-based models of care. In the case of incurable oncologic and hematologic cancers, a value-based model of care should plan advanced care on patients' needs and include the quality of death as an outcome. The integration of early palliative care into standard oncologic care for patients with advanced cancers represents a recent innovative model of assistance whose benefits for patients and caregivers are now widely recognized. The key elements underlying the reasons behind these benefits are the multidisciplinary collaboration (teamwork), an honest and empathetic communication between the early palliative care team, the patient, and the caregiver (rapport building), and the ability to detect changes in the physical/psychosocial wellbeing of the patient, along the whole disease trajectory (constant monitoring).

Methods

This community case study documents the quantitative and qualitative results of a long term clinical and research experience in delivering early palliative care service to address both solid and blood cancer patients' and their primary caregivers' needs.

Results

Data showed decreased use of chemotherapy, blood transfusions and referral to intensive care units near the end of life; increased life expectancy; improved symptom burden and mood; increased frequency of goals-of-care and advanced care planning conversations. Hope perception among bereaved caregivers was associated with resilience and realistic expectations raising from honest communication with the early palliative care team and appreciation toward the model. Patients and caregivers perceived the possibility of a good death as realistic and not as an unlikely event as it was for patients and caregivers on standard oncologic care only. Gratitude expressions toward the model and the team were frequently identified in their reports and positively associated with communication and spirituality.

Conclusions

These findings are discussed in the context of an updated literature review regarding value-based care and suggest that early palliative care integrated into standard oncology care may be considered as an effective model of value-based care.

"More than conquerors": a qualitative analysis of war metaphors for patients with cancer

PURPOSE

Meaning-making is fundamental to the cancer experience and communication within cancer care is saturated with metaphors. The objective of this study was to better understand the impact and function of war metaphors among patients with cancer.

METHODS

Patients at the Duke Cancer Center were purposively sampled for inclusion based on type and stage of their cancer. Each patient underwent a semi-structured interview to explore their use of metaphors in their lived experience with cancer. Qualitative interviews broadly explored two key areas of interest: (1) frequency and use of metaphors to describe cancer diagnosis, treatment, or survivorship; (2) function and impact of the war metaphor on the patient experience of cancer.

RESULTS

Fifteen participants with either breast, lung, or colorectal cancer were interviewed. Most patients used metaphor themes of journey, war, and mystery to describe their cancer. All patients with non-metastatic disease used war metaphors and described how these metaphors facilitated meaning-making by promoting positivity and situating cancer within a larger life story. The few patients who did not use war metaphors had metastatic disease, and they explained that war metaphors were unhelpful due to feeling a lack of control over their metastatic disease and outcomes.

CONCLUSION

The war metaphor should remain an integral part of cancer care. Disregarding war metaphors robs patients of an important framework for meaning-making-one that may promote strength, continuity, and resilience in navigating cancer.

Gratitude among advanced cancer patients and their caregivers: The role of early palliative care

OBJECTIVE

A cancer diagnosis represents a unique trauma, given its life-threatening, multidimensional, and uncertain nature. Gratitude is a construct representing the emotional state that arises when individuals recognize that a benefit has been received as a result of someone else's action or a spiritual entity's intervention. Based on the positive psychological wellbeing, gratitude has been associated with improved health outcomes even in the disease setting. Thus, the models of care that foster gratitude should be adopted in the clinical context. This study aims to explore whether and how gratitude may originate in patients with advanced cancer and their caregivers undergoing early palliative care (EPC).

METHODS

We analyzed 251 reports from 133 patients and 118 caregivers describing their clinical experience in two EPC units. The sources of gratitude were identified and ranked based on their frequencies. Words expressing gratitude and words referring to communication and spirituality were collected by means of the Linguistic Inquiry and Word Count software and correlated.

RESULTS

In total, 123 (92.5%) of 133 patients' and 97 (82.2%) of 118 caregivers' reports, respectively, included explicit or implicit expressions of gratitude. Gratitude was associated specifically with successful physical symptom management, emotional support, improved attitude toward death, better information, humanity, and the familiar environment. The use of words of gratitude in patients' reports was positively correlated with the use of words referring to communication (r = .215, p = .026) and spirituality (r = .612, p <.001).

CONCLUSION

Our results suggest that interventions within the EPC model based on doctor-patient-caregiver communication may allow patients and caregivers to experience a feeling of gratitude, and this may represent a resource to be exploited to improve their physical and psychosocial wellbeing.

Development and Validation of a Predictive Model for Toxicity of Neoadjuvant Chemoradiotherapy in Rectal Cancer in the CAO/ARO/AIO-04 Phase III Trial

Background: There is a lack of predictive models to identify patients at risk of high neoadjuvant chemoradiotherapy (CRT)-related acute toxicity in rectal cancer. Patient and Methods: The CAO/ARO/AIO-04 trial was divided into a development (n = 831) and a validation (n = 405) cohort. Using a best subset selection approach, predictive models for grade 3−4 acute toxicity were calculated including clinicopathologic characteristics, pretreatment blood parameters, and baseline results of quality-of-life questionnaires and evaluated using the area under the ROC curve. The final model was internally and externally validated. Results: In the development cohort, 155 patients developed grade 3−4 toxicities due to CRT. In the final evaluation, 15 parameters were included in the logistic regression models using best-subset selection. BMI, gender, and emotional functioning remained significant for predicting toxicity, with a discrimination ability adjusted for overfitting of AUC 0.687. The odds of experiencing high-grade toxicity were 3.8 times higher in the intermediate and 6.4 times higher in the high-risk group (p < 0.001). Rates of toxicity (p = 0.001) and low treatment adherence (p = 0.007) remained significantly different in the validation cohort, whereas discrimination ability was not significantly worse (DeLong test 0.09). Conclusion: We developed and validated a predictive model for toxicity using gender, BMI, and emotional functioning. Such a model could help identify patients at risk for treatment-related high-grade toxicity to assist in treatment guidance and patient participation in shared decision making.
