A conceptual model of social networks and mechanisms of cancer mortality, and potential strategies to improve survival

A validation study for measuring Asian- and Hispanic-serving sociocultural institutions in neighborhoods using business listing data and potential implications for health

Ethnic enclaves influence the health of Asian American and Hispanic or Latinx/a/o populations, likely via neighborhood social, economic, and built environments. To facilitate studies aiming to disentangle these specific neighborhood mechanisms, we describe the creation and validation of two novel measures-Asian-serving and Hispanic-serving sociocultural institutions (SCIs)-to estimate the social, cultural, and economic character of ethnic enclaves in California. Business listing data were used to identify SCIs or businesses that promote cultural and social identity, including arts, civic, historical, religious, social service, and membership organizations. Keyword searches of business names were used to identify potential Asian- or Hispanic-serving SCIs. An online audit of 1,627 businesses within 12 cities confirmed the validity of using keyword searches to assess whether census tracts were high or low in Asian- or Hispanic-serving SCIs (sensitivity: 63%-100%, specificity: 86%-95%; positive predictive value: 63%-89%). In exploratory regression analyses, high presence of SCIs (compared to low presence) may be associated with neighborhood-level health indicators, including greater percentages of residents who had an annual checkup in majority Asian census tracts and lower percentages of residents who were current smokers in majority Asian and Hispanic census tracts. This approach advances methodology in measurement of neighborhood sociocultural environments.

Cancer Patients' Social Relationships During 3 Years After Diagnosis-Generic and Cancer-Specific Social Networks

BACKGROUND

Social relationships are important health resources and may be investigated as social networks. We measured cancer patients' social subnetworks divided into generic social networks (people known to the patients) and disease-specific social networks (the persons talked to about the cancer) during 3 years after diagnosis.

METHOD

Newly diagnosed patients with localized breast cancer (n = 222), lymphoma (n = 102), and prostate cancer (n = 141) completed a questionnaire on their social subnetworks at 2-5 months after diagnosis and 9, 18, and 36 months thereafter. Generic and cancer-specific numbers of persons of spouse/partner; other family; close relatives, in detail; and friends were recorded as well as cancer-specific numbers of persons in acquaintances; others with cancer; work community; healthcare professionals; and religious, hobby, and civic participation. The data was analyzed with regression models.

RESULTS

At study entry, most patients had a spouse/partner, all had close relatives (the younger, more often parents; and the older, more often adult children with families) and most also friends. The cancer was typically discussed with them, and often with acquaintances and other patients (74-86%). Only minor usually decreasing time trends were seen. However, the numbers of distant relatives and friends were found to strongly increase by the 9-month evaluation (P < 0.001).

CONCLUSION

Cancer patients have multiple social relationships and usually talk to them about their cancer soon after diagnosis. Most temporal changes are due to the natural course of life cycle. The cancer widened the patients' social networks by including other patients and healthcare professionals and by an increased number of relatives and friends.

Neighborhood Collective Efficacy: A Longitudinal Social Determinant of Access to Medical Care Among Recently Immigrated Latina Young Adults

The present longitudinal study examined changes in perceived access to health care among a recently immigrated cohort of Latina young adults who were assessed annually during their first 3 years in the United States. A parallel process growth model of perceived access to health care and neighborhood collective efficacy was examined, accounting for socioeconomic indicators and immigration status. Five hundred thirty Latina young adults (ages 18-23) participated at baseline assessment, and approximately 95% were retained over three annual assessment time points. Participants' mean level of perceived access to health care increased during their initial 3 years in the United States. Women who reported more of an increase in perceived access to health care tended to also indicate increased neighborhood collective efficacy relative to their peers during their first 3 years in the United States. Findings offer important information about the individual- and community-level factors that influence recently immigrated Latinas' health care access.

App-based interventions to improve cancer outcomes rely on informational support from professionals: a systematic review

The importance of social support for cancer patients is well-established, and mobile applications hold promise for implementation. This systematic review examines app-based interventions with social support components for cancer patients, investigating the use of different support functions from different sources and the impact on cancer-related symptoms and psychological outcomes. A systematic search across five databases (EMBASE, Scopus, PsycINFO, PubMed, Web of Science) yielded 449 records, of which 17 studies (12 controlled designs) were included. Two independent reviewers extracted data and assessed study quality, revealing a high risk of bias across studies. Social support was implemented through different app functions, including contact/chat functions (n = 9), automatic alerts based on app input (n = 6) and discussion forums (n = 5). Social support predominantly focused on informational support (n = 17), mostly from healthcare professionals. Emotional support was less common (n = 7). Results indicated some promising intervention effects for pain, fatigue, nausea/vomiting, insomnia, constipation and overall symptom distress, but heterogeneous effects for health-related quality of life. Overall, results were mixed, but indicate that mobile apps incorporating social support may hold promise for cancer patients. However, future studies should focus on measuring and reporting social support as an intervention mechanism to systematically investigate its specific impact and improve effectiveness.HighlightsApps for cancer patients predominantly include informational social supportEmotional social support is substantially less frequently includedApps focus on formal support sources like healthcare professionalsFirst results are somewhat promising for improving cancer-related symptoms.

Equipping Faith-Based Communities for Cancer Support Ministry: A Pilot Study of Cancer Support Training for Members of African-American Churches in the USA

Church-academic partnerships focused on cancer, generally target cancer screening and prevention, with few focusing explicitly on cancer survivors. With the population of cancer survivors steadily increasing, highlighting the value of faith-based cancer support ministry is paramount. However, many churches may not have the resources to integrate relevant cancer support ministry and may need to identify ways to reach cancer survivors. We piloted cancer support training to help church members to start a cancer support ministry with African-American churches in Milwaukee, WI. We sought to measure the feasibility of a two-day training workshop to build the capacity of churches through recruiting and training church members on how to foster social support and to disseminate cancer information and resources throughout their churches. Our study was guided by the social networks and social support framework, which we applied to cancer survivorship. Our study supports the feasibility of engaging churches in a virtual training to support the development of cancer support ministries to address the needs of African-American cancer survivors. Based on our recruitment success, workshop attendance, evaluation and retention, our results suggest that a two-day workshop was successful in facilitating the initiation of cancer support ministries within African-American churches.

Negotiating cancer alone: A qualitative study exploring care experiences of racially and ethnically diverse women diagnosed with breast cancer during COVID-19

COVID-19 has critically impacted cancer care services including reduced screenings, diagnoses, and surgeries; particularly among Black and Latina/x women who already suffer worse outcomes. This qualitative study explored the care experiences of a diverse sample of breast cancer survivors (N = 21; 7 Black, 4 Hispanic, 10 White) undergoing treatment during the pandemic via online semi-structured interviews. Grounded theory analysis yielded the core category "negotiating cancer alone," that included: (1) psychological distress, negotiating the cancer trajectory in isolation; (2) provider/healthcare system diagnostic and treatment delays; (3) heightened anxiety about treatment delays causing cancer progression; (4) supportive care limitations; and (5) disparate experiences of cancer care disruptions. Black and Latina/x women described greater delays in care, financial challenges, treatment complications, and insurance limitations than White women. The study identifies cancer patients' pandemic-related psychological, healthcare system, and health equity challenges and suggests recommendations to support their increased psychological needs during oncologic care disruptions.

Study Protocol for the Social Interventions for Support During Treatment for Endometrial Cancer and Recurrence (SISTER) study: a community engaged national randomized trial

Aim: Social isolation in cancer patients is correlated with prognosis and is a potential mediator of treatment completion. Black women with endometrial cancer (EC) are at increased risk for social isolation when compared with White patients. We developed the Social Interventions for Support during Treatment for Endometrial Cancer and Recurrence (SISTER) study to compare and evaluate interventions to address social isolation among Black women with high-risk EC in USA. The primary objective of the SISTER study is to determine whether virtual support interventions improve treatment completion compared with Enhanced Usual Care. Secondary objectives include comparing effectiveness virtual evidence-based interventions and evaluating barriers and facilitators to social support delivery. Patients & methods: This is a multi-site prospective, open-label, community-engaged randomized controlled trial, consisting of three intervention arms: enhanced usual care, facilitated support group and one-to-one peer support. Primary outcome will be measured using relative dose. Qualitative semi-structured interviews will be conducted with a subset of participants to contextualize the relative degree or lack thereof of social isolation, over time. Data analysis: Primary analysis will be based on an intent-to-treat analysis. Multivariable analysis will be performed to determine the effect of the intervention on the primary and secondary outcomes of interest, relative dose and social isolation score. Semi-structured interviews will be qualitatively analyzed using inductive and deductive approaches of content analysis. Discussion/conclusion: Endometrial cancer mortality disproportionately affects Black women, and social isolation contributes to this disparity. The SISTER study aims to identify whether and to what extent differing social support vehicles improve key outcomes for Black women in the United States with high-risk EC. Clinical Trial Registration: NCT04930159 (ClinicalTrials.gov).

Equity in Cancer and Chronic Disease Prevention through a Multi-Pronged Network Intervention: Works-in-Progress

The increasing rates of cancer incidence are disproportionately borne by populations that are ineligible for screening and historically marginalized populations. To address this need, our community-centered model seeks to catalyze the widespread diffusion of evidence-based information and resources (e.g., community-based organizations, federally qualified health centers) to reduce the risks of cancer, chronic disease, and other conditions. In this study, we tested whether improving personal health literacy (i.e., confidence in seeking information) and enabling successful information transfer (i.e., intention to share the specific information learned through the program) among community residents could contribute to greater diffusion intention (i.e., number of network members with whom residents plan to share information and resources). The current study used post-intervention surveys, which were administered to Chicago residents who were 18 years or older and had participated in the program. Among the 1499 diverse Chicago residents, improved personal health literacy was associated with greater diffusion intention (ORs = 2.00-2.68, 95% CI [1.27-4.39], p ≤ 0.003). Successful information transfer was associated with greater diffusion, especially for cancer and other chronic disease risk reductions (ORs = 3.43-3.73, 95% CI [1.95-6.68], p < 0.001). The findings highlight the potential gains for health equity through sustainable, scalable, multi-sectoral partnerships.

Personal Social Networks and Care-Seeking for Head and Neck Cancer: A Qualitative Study

OBJECTIVES

To investigate the role of patients' personal social networks (SNs) in accessing head and neck cancer (HNC) care through patients' and health care workers' (HCWs) perspectives.

STUDY DESIGN

Qualitative study.

SETTING

Tertiary HNC centers at 2 academic medical centers, including 1 safety net hospital.

METHODS

Patients with newly diagnosed HNC, and HCWs caring for HNC patients, aged ≥18 years were recruited between June 2022 and July 2023. Semistructured interviews were conducted with both patients and HCWs. Inductive and deductive thematic analysis was performed with 2 coders (κ = 0.82) to analyze the data.

RESULTS

The study included 72 participants: 42 patients (mean age 57 years, 64% female, 81% white), and 30 HCWs (mean age 42 years, 77% female, 83% white). Four themes emerged: (1) Patients' SNs facilitate care through various forms of support, (2) patients may hesitate to seek help from their networks, (3) obligations toward SNs may act as barriers to seeking care, and (4) the SN composition and dedication influence care-seeking.

CONCLUSION

Personal SNs play a vital role in prompting early care-seeking among HNC patients. SN-based interventions could enhance care and improve outcomes for HNC patients.

The Integration of Value Assessment and Social Network Methods for Breast Health Navigation Among African Americans

OBJECTIVES

A major strategy to reduce the impact of breast cancer (BC) among African Americans (AA) is patient navigation, defined here as individualized assistance for reducing barriers to healthcare use. The primary focus of this study was to estimate the added value of incorporating breast health promotion by navigated participants and the subsequent BC screenings that network members may obtain.

METHODS

In this study, we compared the cost-effectiveness of navigation across 2 scenarios. First, we examine the effect of navigation on AA participants (scenario 1). Second, we examine the effect of navigation on AA participants and their networks (scenario 2). We leverage data from multiple studies in South Chicago. Our primary outcome (BC screening) is intermediate, given limited available quantitative data on the long-term benefits of BC screening for AA populations.

RESULTS

When considering participant effects alone (scenario 1), the incremental cost-effectiveness ratio was $3845 per additional screening mammogram. When including participant and network effects (scenario 2), the incremental cost-effectiveness ratio was $1098 per additional screening mammogram.

CONCLUSION

Our findings suggest that inclusion of network effects can contribute to a more precise, comprehensive assessment of interventions for underserved communities.

Association of emotional support with quality of life, mental health, and survival in older adults with gastrointestinal malignancies-Results from the CARE registry

BACKGROUND

Emotional support (ES) is the most frequently reported support need among older adults with cancer. Yet, the association of ES with cancer outcomes is largely unknown. This study examined the association of ES with health-related quality of life (HRQoL), mental health, and survival among older adults with gastrointestinal (GI) malignancies.

METHODS

We included newly diagnosed older adults (≥60 years) with GI cancer undergoing self-reported geriatric assessment at their first clinic visit. ES was measured using an adaptation of the Medical Outcomes Study (dichotomized adequate ES vs. inadequate ES). Outcomes included physical and mental HRQoL, anxiety, depression, and survival. Multivariable linear regression evaluated the association between ES and HRQoL scores. Multivariable logistic regression evaluated the association of ES with anxiety and depression. All models were adjusted for age at geriatric assessments, race, sex, and cancer type/stage.

RESULTS

795 participants were included. Median patient age was 68 years (IQR: 64-74), 58% were male, and most cancers were either colorectal (37.9%) or pancreatic (30.8%). Most (77.6%) had adequate ES. Patients with inadequate ES were more likely to be Black (31.5 vs. 20.8%, p = 0.005), disabled (24.1 vs. 10.4%, p < 0.001), widowed/divorced (54.2 vs. 24.8%, p < 0.001) and had lower physical and mental HRQoL t-scores (Physical β: -3.35, 95% CI: -5.25, -1.46; Mental β: -2.46, 95% CI: -4.11, -0.81) and higher odds of depression (aOR: 2.22, CI: 1.34-3.69). This study found no difference between those with adequate ES versus inadequate ES in the proportion of deaths within 1 year of diagnosis (24.3% vs. 24.2%, p = 0.966), or within 2 years of diagnosis (32.4% vs. 33.2%, p = 0.126).

CONCLUSIONS

Older adults with inadequate ES have worse physical and mental HRQoL and higher odds of depression compared to those with adequate ES.

Third Places for Older Adults' Social Engagement: A Scoping Review and Research Agenda

BACKGROUND AND OBJECTIVES

Neighborhood places that facilitate older residents to meet and interact (third places) receive an increasing research interest as studies have consistently shown the benefits of social engagement for older adults' health. This scoping review synthesized the findings of studies examining the role of third places in older adults' social engagement.

RESEARCH DESIGN AND METHODS

Searching 5 databases (CINAHL, Medline, PsycInfo, Scopus, and Web of Science) in October 2021, this study identified quantitative and qualitative studies that examined the relationships between third places and social engagement (interaction and network) among older adults.

RESULTS

A total of 32 studies (12 quantitative and 20 qualitative studies) met the eligibility criteria. These studies examined 4 types of third place, namely, community facilities, local businesses, open/green spaces, and transition spaces. More than two thirds of the studies reviewed found that access to community facilities, local businesses, and open/green spaces were related to older adults' social interaction. For the relationships between third places and social networks, the importance of accessible local businesses and the quality of open/green spaces was supported by fewer studies.

DISCUSSION AND IMPLICATIONS

The findings of quantitative and qualitative studies suggest that local places that are convenient to visit and comfortable to stay in for older adults are likely to enhance their social interaction and network. However, more specific evidence is needed to inform the planning and design of third places. The review discusses future research topics that address the gaps identified in the current literature.

Investigating the Joint Effect of Allostatic Load among Lesbian, Gay, and Bisexual Adults with Risk of Cancer Mortality

Sexual minorities (SM) have higher chronic physiologic stress as indicated by allostatic load (AL), which may be explained in part by consistent experiences of discriminatory practices. This is one of the first studies to examine the joint effects of SM status and AL on the association with long-term risk for cancer death. Retrospective analyses were conducted on 12,470 participants using National Health and Nutrition Examination Survey (NHANES) from years 2001 through 2010 linked with the National Death Index through December 31, 2019. Cox proportional hazards models estimated adjusted hazard ratios (aHRs) of cancer deaths between groups of SM (those reporting as gay, lesbian, bisexual, or having same-sex sexual partners) status and AL. SM adults living with high AL (n = 326) had a 2-fold increased risk of cancer death (aHR: 2.55, 95% CI: 1.40-4.65) when compared to straight/heterosexual adults living with low AL (n = 6674). Among those living with high AL, SM (n = 326) had a 2-fold increased risk of cancer death (aHR: 2.26, 95% CI: 1.33-3.84) when compared to straight/heterosexual adults with high AL (n = 4957). SM with high AL have an increased risk of cancer mortality. These findings highlight important implications for promoting a focused agenda on cancer prevention with strategies that reduce chronic stress for SM adults.

How effective is peer-to-peer support in cancer patients and survivors? A systematic review

PURPOSE

Core components of peer-to-peer (PTP) support for cancer survivors include informational, emotional, and psychosocial aspects. Previous literature on peer support in cancer includes both professionally and peer-led support. Our objective was to summarize studies on the effects of non-professionally led PTP support in cancer.

METHODS

We performed a systematic research on studies in PTP support of adult cancer survivors with an interventional design, comparing outcomes of PTP support against any control. We included all studies with a precise definition of a PTP support, published from January 2000 up to March 2023 in peer-reviewed journals in English or German.

RESULTS

Out of N = 609 identified publications, we were are able to include n = 18 randomized-controlled trials (RCTs) fulfilling our inclusion criteria. Main settings were dyadic support via telephone, face-to-face (FTF), and web-based online support. Most common outcomes were distress, depressive symptoms, anxiety, and quality of life (QoL). Overall, we found only small effects of PTP support on depression/anxiety, coping, or sexual functioning. Beneficial effects associated with the PTP intervention were apparent in particular in BRCA, in FTF settings, and in assessments of cancer-specific QoL outcomes.

CONCLUSION

This review shows that there are a few RCT investigating the effect of PTP support with short-term effects. Overall, there is a need for more RCTs with high methodological standards to evaluate the effectiveness of PTP support.

Understanding social network support, composition, and structure among cancer caregivers

OBJECTIVE

We examined the social network support, composition, and structure of pediatric cancer caregivers.

METHODS

We used a self-report survey to collect egocentric social network data from 107 caregivers of pediatric cancer patients and calculated descriptive statistics to examine cancer-related support network composition, function, and structure. We then ran logistic regressions to examine the relationships between network characteristics and overall satisfaction with social support.

RESULTS

Family members were the most common source of emotional support and logistical support, and health care providers were the most common source of informational support. Participants perceived the "most helpful" forms of support as being: (1) emotional support from family and health care providers; (2) informational support from health care providers and other cancer caregivers; and (3) logistical support from family. Overall, caregivers wished that 9.8% of their network ties had provided more support, with family members being the most common alter type to disappoint caregivers and offer less support than needed/expected. Caregivers who reported higher network disappointment (having network members who offered less support than needed/expected) were significantly less satisfied with emotional support than those with lower network disappointment (Odds Ratio = 0.18, p = 0.02), and caregivers with higher network disappointment were significantly less satisfied with logistical support compared to those with lower network disappointment (Odds Ratio = 0.14, p = 0.01).

CONCLUSION

Our results show differences in the nature of social support provided by different types of network members. These findings have implications for tailoring social network interventions to improve caregiver and family outcomes.

Preventing metastatic recurrence in low-risk ER/PR + breast cancer patients-a retrospective clinical study exploring the evolving challenge of persistence with adjuvant endocrine therapy

PURPOSE

In the genomic era, more women with low-risk breast cancer will forego chemotherapy and rely on adjuvant endocrine therapy (AET) to prevent metastatic recurrence. However, some of these patients will unfortunately relapse. We sought to understand this outcome. Preliminary work suggested that early discontinuation of AET, also known as non-persistence, may play an important role. A retrospective analysis exploring factors related to our breast cancer patients' non-persistence with AET was performed.

METHODS

Women who underwent Oncotype-DX® testing between 2011 and 2014 with minimum 5 years follow-up were included. 'Low risk' was defined as Oncotype score < 26. Outcomes of recurrence and persistence were determined by chart review. Patient, tumor and treatment factors were collected, and persistent versus non-persistent groups compared using multivariable ANOVA and Fisher Chi square exact test.

RESULTS

We identified six cases of distant recurrence among low-risk patients with a median follow-up of 7.7 years. Among them, five of six patients (83%) were non-persistent with AET. The non-persistence rate in our cohort regardless of recurrence was 57/228 (25%). Non-persistent patients reported more severe side effects compared with persistent patients (p = 0.002) and were more likely to be offered a switch in endocrine therapy, rather than symptom-relief (p = 0.006). In contrast, persistent patients were 10.3 times more likely to have been offered symptom-alleviating medications compared with non-persistent patients (p < 0.001). A subset analysis revealed that patients who persisted with therapy had a higher Oncotype-DX® score than patients who discontinued early (p = 0.028).

CONCLUSION

Metastatic recurrence in low-risk breast cancer patients may be primarily due to non-persistence with endocrine therapy. Further work is needed to optimize care for patients who struggle with side effects. To our knowledge, these are the first published data suggesting that Oncotype-DX® score may influence persistence with AET.

Development and Preliminary Validation of the Questionnaire "Evaluation of the Constitution of Social Circles" in Patients Treated for Cancer of the Upper Aerodigestive Tract

PURPOSE

The constitution of social circles around patients treated for cancer of the upper aerodigestive tract (UADT) has a major influence on factors that affect quality of life (QOL) but is poorly assessed, mainly due to a lack of tools. The objective of this study is to develop a questionnaire that assesses the constitution of social circles in a population treated for UADT cancer and to analyze the construct (structural and clinical validity) and criterion validity.

METHODS

The Evaluation of the Constitution of Social Circles (ECSC) questionnaire was developed in French by a committee of experts. Structural validity was analyzed using inter-item correlations. The scores of a group of patients treated for UADT cancer were compared with those of a group of healthy subjects (clinical validity). For criterion validity, the ECSC scores were compared to those from various questionnaires that assess social functioning (QFS), psychological status (HAD), perceived speech impairment (PHI), and QOL (EORTC QLQ-H&N35) in patients.

RESULTS

Structural validity shows low to moderate inter-item correlations which is consistent with the construction of the questionnaire not assessing underlying concepts. Clinical validity was satisfactory regarding the frequency of contact (p = 0.01), satisfaction with the frequency of contact in the private circle (p = 0.03), and the size of the social circles of family and friends (p ≤ 0.01). Criterion validity was adequate with moderate correlations between the ECSC scores and the QFS sub-scores of interest (rs > 0.56, p < 0.05). Anxiety (HAD) had a low correlation (|rs| = 0.46, p < 0.05) with satisfaction with exchanges and the frequency of contact with family. Satisfaction with exchanges with the private circle was moderately correlated with the EORTC QLQ-H&N35 score (rs = 0.56, p = 0.01) and showed a negative trend on the PHI (rs < -0.39, p ≥ 0.05).

CONCLUSION

While the test-retest reliability is yet to be evaluated and the sample size should be increased, this preliminary study shows that the ECSC is a valid tool for assessing the constitution of social circles in patients treated for UADT cancer. It highlights the links between social circles and their functional impact on communication and QOL.

The role of social networks in the self-management support for young women recently diagnosed with breast cancer

It is widely acknowledged that social network support plays an important role in the quality of life and illness management of breast cancer survivors. However, the factors and processes that enable and sustain such support are less well understood. This paper reports baseline findings from a prospective UK national cohort of 1,202 women with breast cancer (aged <50 years at diagnosis), recruited before starting treatment, conducted in 2016-2019. Descriptive, univariate and multivariate regression analyses explored associations between the individual, and network member characteristics, and the type of support provided. Social network members provided a substantial level of illness-related, practical and emotional support. Highest contribution was provided by friends, followed by close family members. The social network members of women who did not have a partner provided a higher level of support than those in networks with a partner. Women without higher education were more reliant on close family members than those with higher education, and this was more so for women without a partner. Women with higher education without a partner were more reliant on friends and were overall best supported. Women without higher education who did not have a partner were overall least well supported. They had much smaller networks, were highly reliant on close family members, and on high level contributions from all network members. There is a need to develop network-based interventions to support people with a cancer diagnosis, prioritising support for the groups identified as most at risk. Interventions that support engagement with existing network members during treatment, and those that help extend such networks after treatment, are likely to be of benefit. A network perspective can help to develop tailored support and interventions by recognising the interactions between network and individual level processes.

Lack of a caregiver is associated with shorter survival in myeloma patients undergoing autologous stem cell transplantation

There is increasing evidence that social infrastructure and a healthy social network can improve cancer survival. Mayo Clinic has an outpatient stem cell transplantation program for myeloma. Safe outpatient transplantation requires a caregiver to be present. Patients lacking a caregiver are transplanted as an inpatient. We reviewed outcomes on over 2000 patients with multiple myeloma, 2103 transplanted as an outpatient compared with 41 hospitalized for transplantation. Although progression-free survival following transplantation was identical between the two groups, overall survival was shorter in those hospitalized. This suggests that the absence of a caregiver for transplantation is an important surrogate of the social infrastructure associated with poor outcomes in transplanted patients with multiple myeloma.

Patient Navigation Can Improve Breast Cancer Outcomes among African American Women in Chicago: Insights from a Modeling Study

African American (AA) women experience much greater mortality due to breast cancer (BC) than non-Latino Whites (NLW). Clinical patient navigation is an evidence-based strategy used by healthcare institutions to improve AA women's breast cancer outcomes. While empirical research has demonstrated the potential effect of navigation interventions for individuals, the population-level impact of navigation on screening, diagnostic completion, and stage at diagnosis has not been assessed. An agent-based model (ABM), representing 50-74-year-old AA women and parameterized with locally sourced data from Chicago, is developed to simulate screening mammography, diagnostic resolution, and stage at diagnosis of cancer. The ABM simulated three counterfactual scenarios: (1) a control setting without any navigation that represents the "standard of care"; (2) a clinical navigation scenario, where agents receive navigation from hospital-affiliated staff; and (3) a setting with network navigation, where agents receive clinical navigation and/or social network navigation (i.e., receiving support from clinically navigated agents for breast cancer care). In the control setting, the mean population-level screening mammography rate was 46.3% (95% CI: 46.2%, 46.4%), the diagnostic completion rate was 80.2% (95% CI: 79.9%, 80.5%), and the mean early cancer diagnosis rate was 65.9% (95% CI: 65.1%, 66.7%). Simulation results suggest that network navigation may lead up to a 13% increase in screening completion rate, 7.8% increase in diagnostic resolution rate, and a 4.9% increase in early-stage diagnoses at the population-level. Results suggest that systems science methods can be useful in the adoption of clinical and network navigation policies to reduce breast cancer disparities.

Social support and outcomes in older adults with lung cancer

BACKGROUND

Insufficient social support is associated with increased mortality among older adults. Lung cancer is primarily a disease of older adults and is the leading cause of all cancer deaths. We assessed the association of social support with outcomes among older adults with lung cancer.

MATERIALS AND METHODS

Adults age 65 and older with lung cancer with a completed geriatric assessment (GA) were assessed. Emotional social support (ES) and tangible (material, instrumental) support (TS) measures and patient characteristics were obtained from the GA. The electronic health record was used to extract clinical variables. Simple linear regression models evaluated the association between social support scales with patient and clinical factors.

RESULTS

79 adults were assessed. White race was positively associated with ES score (p=.04), while higher BMI (p=.03), depression (p=.03) and anxiety (p=.02) were associated with worse ES. Higher BMI was associated with higher/better TS score (p=.02) while living alone was associated with lower/worse TS score (p=.03). Completion of platinum-based doublet chemotherapy with immunotherapy as planned was associated with higher ES scores (p=.02) and higher TS scores (p=.02). Disease progression was associated with lower ES scores (p=.03).

CONCLUSION

Social support may influence clinical outcomes in older adults with lung cancer. As lung cancer often portends to poor prognosis, social support may be an important prognostic indicator.

Feasibility, usability, and acceptability of personalized web-based assessment of social network and daily social support interactions over time

Purpose

The purpose of this study was to test the feasibility, usability, and acceptability of implementing a web-based method for collecting social network and longitudinal daily interaction data from cancer survivors and their caregivers.

Methods

Young adult and sexual/gender minority cancer survivors and their informal caregivers were recruited as dyads. Feasibility data, including enrollment and retention, were captured. Individual social network data were collected at baseline and used to individualize daily electronically delivered surveys assessing characteristics of daily social support-related interactions with identified network members for 14 days. Follow-up questionnaires assessing usability and exit interviews assessing acceptability were completed at the end of the 2-week study period.

Results

Fourteen survivor-caregiver dyads (28 individual participants) were enrolled and completed all baseline and final measures. Participants completed 85.2% of daily diary reports and reported excellent usability ratings. Acceptability was also high. In qualitative interviews, participants reported enjoying the daily reflection on social support facilitated by our methods.

Conclusions

Our method has been shown to be highly feasible, usable, and acceptable.

Implications for Cancer Survivors

Developing better data collection tools can lead to better understanding of the social support cancer survivors and their caregivers receive, and how the social network structure facilitates or creates barriers to accessing this support.

The Dyadic Cancer Outcomes Framework: A general framework of the effects of cancer on patients and informal caregivers

It is widely acknowledged that cancer affects not only patients but also their friends and family members who provide informal, and typically unpaid, care. Given the dual impact that cancer often has on patients and their informal caregivers (i.e., family members, partners, or friends), an expanded dyadic framework that encompasses a range of health and psychosocial outcomes and includes primary caregivers with a range of relationships to the patients is critically needed. Moreover, an emphasis on the role of social and contextual factors may help the framework resonate with a broader range of patient-caregiver relationships and allow for the development of more effective dyadic interventions. This article describes the development of the Dyadic Cancer Outcomes Framework, which was created to guide future research and intervention development. Using an iterative process, we conducted a conceptual review of currently used dyadic and/or caregiving models and frameworks and developed our own novel dyadic framework. Our novel Dyadic Cancer Outcomes Framework highlights individual- and dyad-level predictors and outcomes, as well as incorporating the disease trajectory and the social context. This framework can be used in conjunction with statistical approaches including the Actor Partner Interdependence Model to evaluate outcomes for different kinds of partner-caregiver dyads. This flexible framework can be used to guide intervention development and evaluation for cancer patients and their primary caregivers, with the ultimate goal of improving health, psychosocial, and relationship outcomes for both patients and caregivers. Future research will provide valuable information about the framework's effectiveness for this purpose.

Understanding the relationship between positive and negative social support and the quality of life among African American breast cancer survivors

PURPOSE

Social support improves several quality of life (QOL) domains among African American breast cancer survivors. How different dimensions of social support are associated with QOL among African American breast cancer survivors may however differ from other populations. This study explores this hypothesis by examining associations of positive social support (supportive interactions that promote affection) and negative social support (non-supportive interactions wherein the provider of support may not have the best intended actions) with QOL among Chicago-based African American breast cancer survivors.

METHODS

Study participants were eligible if they (1) were identified as being an African American female, (2) were at least 18 years of age or older, and (3) were diagnosed with breast cancer during or after navigation was implemented at the study hospital. Participants completed validated questionnaires via telephone or in-person interviews.

RESULTS

Among our sample of 100 participants, positive support was associated with greater mental well-being in non-imputed (Std β=1.60, CI: 0.51, 2.69, p= 0.004) and imputed models (Std β= 1.67, CI: 0.68, 2.73, p=0.001). There was also a weaker inverse association with negative support and mental well-being when using non-imputed data (Std β=-0.82, CI:-1.65, 0.02, p= 0.05).

CONCLUSIONS

Our findings suggest that positive support, in particular, is highly influential for improving mental well-being among African American breast cancer survivors. Simultaneously, negative support appears to be an independent, albeit weaker, determinant of mental well-being.

The Prospective Association of Social Integration With Life Span and Exceptional Longevity in Women

OBJECTIVES

Although stronger social relationships have been associated with reduced mortality risk in prior research, their associations with favorable health outcomes are understudied. We evaluated whether higher social integration levels were associated with longer life span and greater likelihood of achieving exceptional longevity.

METHOD

Women from the Nurses' Health Study completed the Berkman-Syme Social Network Index in 1992 (N = 72,322; average age = 58.80 years), and were followed through 2014 with biennial questionnaires. Deaths were ascertained from participants' families, postal authorities, and death registries. Accelerated failure time models adjusting for relevant covariates estimated percent changes in life span associated with social integration levels; logistic regressions evaluated likelihood of surviving to age 85 years or older among women who could reach that age during follow-up (N = 16,818).

RESULTS

After controlling for baseline demographics and chronic diseases, socially integrated versus isolated women had 10% (95% confidence interval [CI] = 8.80-11.42) longer life span and 41% (95% CI = 1.28-1.54) higher odds of surviving to age 85 years. All findings remained statistically significant after further adjusting for health behaviors and depression.

DISCUSSION

Better social integration is related to longer life span and greater likelihood of achieving exceptional longevity among midlife women. Findings suggest social integration may be an important psychosocial asset to evaluate for promoting longer, healthier lives.

Social Relationships and Functional Impairment in Aging Cancer Survivors: A Longitudinal Social Network Study

BACKGROUND AND OBJECTIVES

The intersection of cancer, treatment, and aging accelerates functional decline. Social networks, through the provision of social support and resources, may slow the progression of functional deterioration. Socioemotional selectivity theory posits that aging and major life events, like cancer, cause an intentional social network pruning to procure and maintain emotionally fulfilling bonds, while shedding weaker, less supportive relationships. However, it is relatively unknown if such network changes impact functional impairment in cancer survivors. This study examined the relationships between changes in the egocentric social network and functional impairment in older adult cancer survivors and a similarly aged group without cancer (older adults).

RESEARCH DESIGN AND METHODS

Data were analyzed from 1,481 community dwelling older adults (n = 201 cancer survivors) aged 57-85 years, from Waves 1 and 2 (2005-2006 and 2010-2011) of the National Social Life, Health and Aging Project. Associations were analyzed with multiple logistic regression.

RESULTS

Cancer survivors and older adults reported similar levels of functional impairment and social network change. Adding 2 new relationships exhibited protective effects against functional impairment, irrespective of cancer status (odds ratio [OR]: 0.64, 95% confidence interval [CI]: 0.41-0.99). Declines in frequent contact were associated with higher odds of functional impairment among cancer survivors (OR: 1.92, 95% CI: 1.15-3.20). Social network components were not significantly associated with functional impairment in older adults.

DISCUSSION AND IMPLICATIONS

Adding new relationships may reduce disability in older adults and increasing network contact may help cancer survivors remain independent. Social network interventions may improve quality of life for older adults.

Occupational disparities in survival in Korean women with cancer: a nationwide registry linkage study

OBJECTIVES

We sought to examine occupational disparities in survival among Korean women diagnosed with cancer.

DESIGN

Population-based, registry-linkage study.

SETTING

South Korea.

PARTICIPANTS

Our study population comprised female workers registered in the Korean national employment insurance programme during 1995-2000 and diagnosed with cancer between 1995 and 2008. A total of 61 110 women with cancer diagnoses was included in analysis. The occupation was categorised into four groups: (1) managers, professionals and technical workers, (2) clerks, (3) service/sales workers and (4) blue-collar workers.

PRIMARY AND SECONDARY OUTCOME MEASURE

Study population were linked to the national death registry until 2009. HRs for mortality adjusting for age and year of diagnosis were calculated in the study sample and subgroups with 10 specific cancer sites including thyroid, breast, stomach, cervix, colon or lung cancer using managers, professionals and technical workers as the reference.

RESULTS

Women in service/sales (HR 1.25, 95% CI 1.15 to 1.35) and blue-collar occupations (HR 1.34, 95% CI 1.25 to 1.44) had poorer survival for all cancer sites combined, while blue-collar workers showed poorer survival for lung (HR 1.41, 95% CI 1.14 to 1.77), breast (HR 1.28, 95% CI 1.06 to 1.54), cervical cancer (HR 1.42, 95% CI 1.02 to 2.06) and non-Hodgkin's lymphoma (HR 1.69, 95% CI 1.09 to 2.77) compared with women in professional and managerial positions.

CONCLUSION

We found substantial and significant inequalities in overall survival by the occupational group among Korean women with cancer, even in the context of universal access to cancer screening and treatment.

Egocentric social networks, lifestyle behaviors, and body size in the Asian Community Health Initiative (CHI) cohort

BACKGROUND

Social networks have been shown to influence lifestyle behaviors in non-Latinx white (NLW) populations. We examined their influence in Asian American, Native Hawaiian and Pacific Islander (AANHPI) women.

METHODS

We included 477 AANHPI women from the Asian Community Health Initiative Study who provided egocentric (degree, density, composition) and epidemiologic (size, types of ties) social network data and data on alcohol intake, physical activity, smoking, diet, and body size. We used logistic regression to evaluate associations of social network measures and dichotomous outcomes, and linear regression for continuous outcomes.

RESULTS

In multivariable-adjusted analyses, higher degree and/or proportion of friends were significantly related to higher Western diet, higher odds of any alcohol consumption, and lower odds of physical inactivity and body mass index (BMI)≥23 kg/m2. Additionally, a higher proportion of NLW in women's networks was related to lower Asian diet but also lower waist size. Community participation was related to higher Western diet and lower Asian diet. By contrast, degree and/or proportion of relatives were positively related to BMI, waist size and to a higher odds of BMI≥23 kg/m2 and of ever smoking 100 cigarettes. Being married was related to fewer alcoholic drinks per week and higher Asian diet. A higher density of relationships with frequent contact was also associated with higher Asian diet.

CONCLUSIONS

AANHPI women with larger proportions of friends and NLWs in their networks had more Western health behaviors and smaller body size. Norms for health behaviors and body size may be influenced by the size, composition, and structure of social networks, relevant to chronic disease prevention.

Cancer-Related Debt and Mental-Health-Related Quality of Life among Rural Cancer Survivors: Do Family/Friend Informal Caregiver Networks Moderate the Relationship?

Social connectedness generally buffers the effects of stressors on quality of life. Is this the case for cancer-related debt among rural cancer survivors? Drawing on a sample of 135 rural cancer survivors, we leverage family/friend informal caregiver network data to determine if informal cancer caregivers buffer or exacerbate the effect of cancer-related debt on mental-health-related quality of life (MHQOL). Using data from the Illinois Rural Cancer Assessment, a survey of cancer survivors in rural Illinois, we estimate the association between cancer-related debt and MHQOL and whether informal caregiver network size and characteristics moderate this association. Over a quarter of survivors (27%) reported cancer-related debt, and those who did reported worse MHQOL. However, this association only held for survivors who had an informal caregiver network. These findings supplement what is already known about the role of social connectedness in cancer survivors' health outcomes. We offer possible explanations for these findings.

Prediagnosis social support, social integration, living status, and colorectal cancer mortality in postmenopausal women from the women's health initiative

BACKGROUND

We evaluated associations between perceived social support, social integration, living alone, and colorectal cancer (CRC) outcomes in postmenopausal women.

METHODS

The study included 1431 women from the Women's Health Initiative who were diagnosed from 1993 through 2017 with stage I through IV CRC and who responded to the Medical Outcomes Study Social Support survey before their CRC diagnosis. We used proportional hazards regression to evaluate associations of social support (tertiles) and types of support, assessed up to 6 years before diagnosis, with overall and CRC-specific mortality. We also assessed associations of social integration and living alone with outcomes also in a subset of 1141 women who had information available on social ties (marital/partner status, community and religious participation) and living situation.

RESULTS

In multivariable analyses, women with low (hazard ratio [HR], 1.52; 95% CI, 1.23-1.88) and moderate (HR, 1.21; 95% CI, 0.98-1.50) perceived social support had significantly higher overall mortality than those with high support (P [continuous] < .001). Similarly, women with low (HR, 1.42; 95% CI, 1.07-1.88) and moderate (HR, 1.28; 95% CI, 0.96-1.70) perceived social support had higher CRC mortality than those with high social support (P [continuous] = .007). Emotional, informational, and tangible support and positive interaction were all significantly associated with outcomes, whereas affection was not. In main-effects analyses, the level of social integration was related to overall mortality (P for trend = .02), but not CRC mortality (P for trend = .25), and living alone was not associated with mortality outcomes. However, both the level of social integration and living alone were related to outcomes in patients with rectal cancer.

CONCLUSIONS

Women with low perceived social support before diagnosis have higher overall and CRC-specific mortality.

Courses of Change in Good Emotional Preparedness for Death and Accurate Prognostic Awareness and Their Associations With Psychological Distress and Quality of Life in Terminally Ill Cancer Patients' Last Year of Life

CONTEXT

Emotional preparedness for death is a distinct but related concept to prognostic awareness (PA). Both allow patients to prepare psychologically and interpersonally for death, but they have primarily been examined in cross-sectional studies.

OBJECTIVES

To 1) explore the courses of change in good emotional preparedness for death and accurate PA and 2) evaluate their associations with severe anxiety symptoms, severe depressive symptoms, and quality of life in cancer patients' last year.

METHODS

For this prospective, longitudinal study, we consecutively recruited 277 terminally ill cancer patients. Aims 1 and 2 were examined by univariate and multivariate generalized estimating equation analyses, respectively.

RESULTS

The prevalence of good emotional preparedness for death was 54.43%-65.85% in the last year, with a significant decrease only 91-180 vs. 181-365 days before death (odds ratio [95% CI] = 0.67 [0.47, 0.97]). Good emotional preparedness for death was associated with a lower likelihood of severe anxiety symptoms (adjusted odds ratio [95% CI] = 0.47 [0.27, 0.79]) and severe depressive symptoms (0.61 [0.39, 0.95]), but not with quality of life (β [95% CI] = 0.49 [-2.13, 3.11]). However, accurate PA improved substantially (55.12%-70.73%) as death approached and accurate PA was positively associated with severe depressive symptoms (2.63 [1.63, 4.25]).

CONCLUSION

Good emotional preparedness for death and accurate PA remained largely stable and improved substantially, respectively, in cancer patients' last year. Both measures were significantly associated with psychological distress. Health care professionals should not only cultivate accurate PA but also promote cancer patients' emotional preparedness for death, which may improve their psychological well-being.

Social Integration, Marital Status, and Ovarian Cancer Risk: A 20-Year Prospective Cohort Study

OBJECTIVE

Low social integration and divorce/widowhood are chronic psychosocial stressors that may affect health. When assessed after cancer diagnosis, they have been associated with poorer survival, but their role in cancer development, particularly ovarian cancer (OvCA), is less understood. We investigated whether social integration and marital status were related to OvCA risk in a large population-based study.

METHODS

Women from the Nurses' Health Study completed the Berkman-Syme Social Network Index and reported their marital status every 4 years starting in 1992 (N = 72,206), and were followed up until 2012 (20-year follow-up period). Multivariate Cox regression models estimated hazard ratios (HRs) and 95% confidence intervals (CIs) of OvCA risk, considering relevant potential confounders, in lagged analyses whereby psychosocial indicators were assessed 4 to 8 years (n = 436 cases) and 8 to 12 years (n = 306 cases) before diagnosis to account for the effects of prediagnostic symptoms on social measures. Secondary analyses evaluated the stability of and cumulative exposure to these social factors on OvCA risk.

RESULTS

Being socially isolated versus integrated was related to an increased OvCA risk 8 to 12 years later (HR = 1.51, 95% CI = 1.07-2.13), but not 4 to 8 years later. Compared with married women, OvCA risk was significantly higher in widowed but not in separated/divorced individuals, with both time periods (e.g., 8-12 years later: HRwidowed = 1.57 [95% CI = 1.15-2.14] versus HRseparated/divorced = 1.13 [95% CI = 0.74-1.72]). Estimates were comparable or stronger when investigating stability in and cumulative effects of social indicators.

CONCLUSIONS

Results suggest higher OvCA risk among socially isolated and widowed women, particularly when such psychosocial stressors were experienced a decade before diagnosis or were sustained over time.

An exerciSe program to improve depression And sleep Disorders in oncology patients: The SAD study

PURPOSE

The purpose of this study was to determine if a structured supervised outpatient exercise program specifically for cancer patients would be associated with improvements in insomnia and depression after attending for 10-weeks.

DESIGN

Descriptive observational study.

SAMPLE AND SETTING

75 adult subjects attended an outpatient hospital based exercise program specifically for cancer patients and coordinated by an exercise physiologist and a physical therapist.

METHOD

Two validated instruments were administered to measure insomnia (Athens Insomnia Instrument) and depression (Zung Self-Rating Depression Scale) at baseline (prior to the start of the program) and repeated after 10-weeks of exercise.

RESULTS

Forty (53.3%) completed the full 10 week program. Of the 40 that completed the program, an improvement in insomnia scores was seen (p-value<0.01) as well as depression scores (p-value = 0.01). Baseline insomnia scores were not different between subjects that did not complete the program compared to those who did (p-value = 0.4401). However, baseline depression scores were higher in subjects who did not complete the program compared to subjects who did (p-value = 0.0462).

CONCLUSIONS

Exercise improved depression and insomnia in cancer patients. By improving these symptoms, mortality, morbidity, and costs may be improved in the oncology population. Exercise programs can provide not only the health benefits of exercise, but also give cancer populations support from their peers which may improve their overall quality of life.
