Tumor Microbiome Diversity and Composition Influence Pancreatic Cancer Outcomes.

Most patients diagnosed with resected pancreatic adenocarcinoma (PDAC) survive less than 5 years, but a minor subset survives longer. Here, we dissect the role of the tumor microbiota and the immune system in influencing long-term survival. Using 16S rRNA gene sequencing, we analyzed the tumor microbiome composition in PDAC patients with short-term survival (STS) and long-term survival (LTS). We found higher alpha-diversity in the tumor microbiome of LTS patients and identified an intra-tumoral microbiome signature (Pseudoxanthomonas-Streptomyces-Saccharopolyspora-Bacillus clausii) highly predictive of long-term survivorship in both discovery and validation cohorts. Through human-into-mice fecal microbiota transplantation (FMT) experiments from STS, LTS, or control donors, we were able to differentially modulate the tumor microbiome and affect tumor growth as well as tumor immune infiltration. Our study demonstrates that PDAC microbiome composition, which cross-talks to the gut microbiome, influences the host immune response and natural history of the disease.

American Cancer Society nutrition and physical activity guideline for cancer survivors.

The overall 5-year relative survival rate for all cancers combined is now 68%, and there are over 16.9 million survivors in the United States. Evidence from laboratory and observational studies suggests that factors such as diet, physical activity, and obesity may affect risk for recurrence and overall survival after a cancer diagnosis. The purpose of this American Cancer Society guideline is to provide evidence-based, cancer-specific recommendations for anthropometric parameters, physical activity, diet, and alcohol intake for reducing recurrence and cancer-specific and overall mortality. The audiences for this guideline are health care providers caring for cancer survivors as well as cancer survivors and their families. The guideline is intended to serve as a resource for informing American Cancer Society programs, health policy, and the media. Sources of evidence that form the basis of this guideline are systematic literature reviews, meta-analyses, pooled analyses of cohort studies, and large randomized clinical trials published since 2012. Recommendations for nutrition and physical activity during cancer treatment, informed by current practice, large cancer care organizations, and reviews of other expert bodies, are also presented. To provide additional context for the guidelines, the authors also include information on the relationship between health-related behaviors and comorbidities, long-term sequelae and patient-reported outcomes, and health disparities, with attention to enabling survivors' ability to adhere to recommendations. Approaches to meet survivors' needs are addressed as well as clinical care coordination and resources for nutrition and physical activity counseling after a cancer diagnosis.

Equitably improving outcomes for cancer survivors and supporting caregivers: A blueprint for care delivery, research, education, and policy.

Cancer care delivery is being shaped by growing numbers of cancer survivors coupled with provider shortages, rising costs of primary treatment and follow-up care, significant survivorship health disparities, increased reliance on informal caregivers, and the transition to value-based care. These factors create a compelling need to provide coordinated, comprehensive, personalized care for cancer survivors in ways that meet survivors' and caregivers' unique needs while minimizing the impact of provider shortages and controlling costs for health care systems, survivors, and families. The authors reviewed research identifying and addressing the needs of cancer survivors and caregivers and used this synthesis to create a set of critical priorities for care delivery, research, education, and policy to equitably improve survivor outcomes and support caregivers. Efforts are needed in 3 priority areas: 1) implementing routine assessment of survivors' needs and functioning and caregivers' needs; 2) facilitating personalized, tailored, information and referrals from diagnosis onward for both survivors and caregivers, shifting services from point of care to point of need wherever possible; and 3) disseminating and supporting the implementation of new care methods and interventions.

Implementing personalized pathways for cancer follow-up care in the United States: Proceedings from an American Cancer Society-American Society of Clinical Oncology summit.

A new approach to cancer follow-up care is necessary to meet the needs of cancer survivors while dealing with increasing volume and provider shortages, knowledge gaps, and costs to both health care systems and patients. An approach that triages patients to personalized follow-up care pathways, depending on the type(s) and level(s) of resources needed for patients' long-term care, is in use in the United Kingdom and other countries and has been shown to meet patients' needs, more efficiently use the health care system, and reduce costs. Recognizing that testing and implementing a similar personalized approach to cancer follow-up care in the United States will require a multipronged strategy, the American Cancer Society and the American Society of Clinical Oncology convened a summit in January 2018 to identify the needed steps to move this work from concept to implementation. The summit identified 4 key strategies going forward: 1) developing a candidate model (or models) of care delivery; 2) building the case for implementation by conducting studies modeling the effects of personalized pathways of follow-up care on patient outcomes, workforce and health care resources, and utilization and costs; 3) creating consensus-based guidelines to guide the delivery of personalized care pathways; and 4) identifying and filling research gaps to develop and implement needed care changes. While these national strategies are pursued, oncology and primary care providers can lay the groundwork for implementation by assessing their patients' risk of recurrence and the chronic and late effects of cancer as well as other health care needs and resources available for care and by considering triaging patients accordingly, referring patients to appropriate specialized survivorship clinics as these are developed, helping to support patients who are capable of self-managing their health, setting expectations with patients from diagnosis onward for the need for follow-up in primary care and/or a survivorship clinic, and improving coordination of care between oncology and primary care.

Correlates of health-related quality of life in African Americans diagnosed with cancer: a review of survivorship studies and the Detroit research on cancer survivors cohort.

Advances in cancer screening and treatment have improved survival after a diagnosis of cancer. As the number of cancer survivors as well as their overall life-expectancy increases, investigations of health-related quality of life (HRQOL) are critical in understanding the factors that promote the optimal experience over the course of survivorship. However, there is a dearth of information on determinants of HRQOL for African American cancer survivors as the vast majority of cohorts have been conducted predominantly among non-Hispanic Whites. In this review, we provide a review of the literature related to HRQOL in cancer survivors including those in African Americans. We then present a summary of published work from the Detroit Research on Cancer Survivors (ROCS) cohort, a population-based cohort of more than 5000 African American cancer survivors. Overall, Detroit ROCS has markedly advanced our understanding of the unique factors contributing to poorer HRQOL among African Americans with cancer. This work and future studies will help inform potential interventions to improve the long-term health of this patient population.

Healthy lifestyle and cancer survival: A multinational cohort study.

Lifestyle factors after a cancer diagnosis could influence the survival of cancer 60 survivors. To examine the independent and joint associations of healthy lifestyle factors with mortality outcomes among cancer survivors, four prospective cohorts (National Health and Nutrition Examination Survey [NHANES], National Health Interview Survey [NHIS], UK Biobank [UKB] and Kailuan study) across three countries. A healthy lifestyle score (HLS) was defined based on five common lifestyle factors (smoking, alcohol drinking, diet, physical activity and body mass index) that related to cancer survival. We used Cox proportional hazards regression to estimate the hazard ratios (HRs) for the associations of individual lifestyle factors and HLS with all-cause and cancer mortality among cancer survivors. During the follow-up period of 37,095 cancer survivors, 8927 all-cause mortality events were accrued in four cohorts and 4449 cancer death events were documented in the UK and US cohorts. Never smoking (adjusted HR = 0.77, 95% CI: 0.69-0.86), light alcohol consumption (adjusted HR = 0.86, 95% CI: 0.82-0.90), adequate physical activity (adjusted HR = 0.90, 95% CI: 0.85-0.94), a healthy diet (adjusted HR = 0.69, 95% CI: 0.61-0.78) and optimal BMI (adjusted HR = 0.89, 95% CI: 0.85-0.93) were significantly associated with a lower risk of all-cause mortality. In the joint analyses of HLS, the HR of all-cause and cancer mortality for cancer survivors with a favorable HLS (4 and 5 healthy lifestyle factors) were 0.55 (95% CI 0.42-0.64) and 0.57 (95% CI 0.44-0.72), respectively. This multicohort study of cancer survivors from the United States, the United Kingdom and China found that greater adherence to a healthy lifestyle might be beneficial in improving cancer prognosis.

Prevalence of neoplasia at colonoscopy among testicular cancer survivors treated with platinum-based chemotherapy.

Testicular cancer survivors (TCS) treated with platinum-based chemotherapy have an increased risk of colorectal cancer (CRC). We determined the yield of colonoscopy in TCS to assess its potential in reducing CRC incidence and mortality. We conducted a colonoscopy screening study among TCS in four Dutch hospitals to assess the yield of colorectal neoplasia. Neoplasia was defined as adenomas, serrated polyps (SPs), advanced adenomas (AAs: ≥10 mm diameter, high-grade dysplasia or ≥25% villous component), advanced serrated polyps (ASPs: ≥10 mm diameter or dysplasia) or CRC. Advanced neoplasia (AN) was defined as AA, ASP or CRC. Colonoscopy yield was compared to average-risk American males who underwent screening colonoscopy (n = 24,193) using a propensity score matched analysis, adjusted for age, smoking status, alcohol consumption and body mass index. A total of 137 TCS underwent colonoscopy. Median age was 50 years among TCS (IQR 43-57) vs 55 years (IQR 51-62) among American controls. A total of 126 TCS were matched to 602 controls. The prevalence of AN was higher in TCS than in controls (8.7% vs 1.7%; P = .0002). Nonadvanced adenomas and SPs were detected in 45.2% of TCS vs 5.5% of controls (P < .0001). No lesions were detected in 46.0% of TCS vs 92.9% of controls (P < .0001). TCS treated with platinum-based chemotherapy have a higher prevalence of neoplasia and AN than matched controls. These results support our hypothesis that platinum-based chemotherapy increases the risk of colorectal neoplasia in TCS. Cost-effectiveness studies are warranted to ascertain the threshold of AN prevalence that justifies the recommendation of colonoscopy for TCS.

Reproductive late effects and testosterone replacement therapy in male childhood cancer survivors: A population-based study (the Fex-Can study).

Childhood cancer survivors are at risk of various endocrine late effects affecting their quality of life. The aim of this study was to assess the prevalence and predictors of endocrine and reproductive outcomes in young adult survivors. A secondary aim was to assess possible associations between testosterone replacement therapy (TRT) and other endocrine, cardiovascular and psychosocial late effects. This nationwide study comprised 1212 male childhood cancer survivors aged 19-40 years, identified through the National Quality Registry for Childhood Cancer in Sweden. Median age at diagnosis during 1981-2017 was 7 (range 0-17) and at study 29 (19-40) years. The study combined self-report survey data with cancer treatment data from the national registry. Hormone-induced puberty was self-reported by 3.8% of the survivors and ongoing TRT by 6.0%. In separate logistic regression analyses, these treatments were associated with hematopoietic stem cell transplantation and cranial radiotherapy. Hormone-induced puberty was additionally associated with younger age at diagnosis. Men with TRT had a higher prevalence of other endocrine deficiencies, cholesterol medication, depressive symptoms and fatigue as well as a lower probability of living with a partner, having a biological child or current occupation. In the total male cohort, 28.2% reported having a biological child. Reassuring reproductive outcomes after less intensive therapies and low frequency of TRT were observed in young adult male childhood cancer survivors treated in the most recent treatment era. However, men with TRT suffered from several other endocrine, cardiovascular and psychosocial late effects, indicating a need for long-term monitoring of this high-risk group.

A randomized prospective trial of an ostomy telehealth intervention for cancer survivors.

BACKGROUND: Cancer survivors with ostomies face complex challenges. This study compared the Ostomy Self-Management Telehealth program (OSMT) versus attention control usual care (UC). METHODS: Three academic centers randomized participants. OSMT group sessions were led by ostomy nurses and peer ostomates (three for ostomates-only, one for support persons, and one review session for both). Surveys at baseline, OSMT completion, and 6 months were primary outcome patient activation (PAM), self-efficacy (SE), City of Hope quality of life-Ostomy (COH-O), and Hospital Anxiety and Depression Scale (HADS). Surveys were scored per guidelines for those completing at least two surveys. Linear mixed effects models were used to select potential covariates for the final model and to test the impact of OSMT within each timeframe. RESULTS: A total of 90 OSMT and 101 UC fulfilled analysis criteria. Arms were well-matched but types of tumors were unevenly distributed (p = .023). The OSMT arm had a nonsignificant improvement in PAM (confidence interval [CI], -3.65 to 5.3]; 4.0 vs. 2.9) at 6 months. There were no significant differences in other surveys. There was a significant OSMT benefit for urinary tumors (four SE domains). Higher OSMT session attendance was associated with post-session improvements in five SE domains (p < .05), two COH-O domains (p < .05), and HADS anxiety (p = .01). At 6 months, there remained improvements in one SE domain (p < .05), one COH-O domain (p < .05), and HADS anxiety (p < .01). CONCLUSIONS: No clear benefit was seen for the OSMT intervention, although there may be an advantage based on type of tumor. Benefit with greater session attendance was also encouraging. PLAIN LANGUAGE SUMMARY: Cancer patients with ostomies have many challenges. We tested a telehealth curriculum compared to usual care. There are indications of benefit for the program for those that attend more sessions and those with urostomies.

Long-term multimorbidity trajectories in older adults: The role of cancer, demographics, and health behaviors.

BACKGROUND: Multimorbidity is associated with premature mortality and excess health care costs. The burden of multimorbidity is highest among patients with cancer, yet trends and determinants of multimorbidity over time are poorly understood. METHODS: Via Medicare claims linked to Cancer Prevention Study II data, group-based trajectory modeling was used to compare National Cancer Institute comorbidity index score trends for cancer survivors and older adults without a cancer history. Among cancer survivors, multinomial logistic regression analyses evaluated associations between demographics, health behaviors, and comorbidity trajectories. RESULTS: In 82,754 participants (mean age, 71.6 years [SD, 5.1 years]; 56.9% female), cancer survivors (n = 11,265) were more likely than older adults without a cancer history to experience the riskiest comorbidity trajectories: (1) steady, high comorbidity scores (remain high; odds ratio [OR], 1.36; 95% CI, 1.29-1.45), and (2) high scores that increased over time (start high and increase; OR, 1.51; 95% CI, 1.38-1.65). Cancer survivors who were physically active postdiagnosis were less likely to fall into these two trajectories (OR, 0.73; 95% CI, 0.64-0.84, remain high; OR, 0.42; 95% CI, 0.33-0.53, start high and increase) compared to inactive survivors. Cancer survivors with obesity were more likely to have a trajectory that started high and increased (OR, 2.83; 95% CI, 2.32-3.45 vs. normal weight), although being physically active offset some obesity-related risk. Cancer survivors who smoked postdiagnosis were also six times more likely to have trajectories that started high and increased (OR, 6.86; 95% CI, 4.41-10.66 vs. never smokers). CONCLUSIONS: Older cancer survivors are more likely to have multiple comorbidities accumulated at a faster pace than older adults without a history of cancer. Weight management, physical activity, and smoking avoidance postdiagnosis may attenuate that trend.

Employment and workdays lost among spouses of cancer survivors: Intersection with gender across cancer treatment status.

BACKGROUND: Cancer patients and survivors have high care needs, often provided by a spouse or partner. The purpose of this study was to elucidate how employment and work loss patterns differed across cancer history/treatment status and gender. METHODS: Using nationally representative data from the Medical Expenditure Panel Survey (2011, 2016, and 2017), the authors linked data across married participants and categorized them by spouses' cancer treatment status (no cancer history, on treatment for cancer, off treatment for cancer). Multivariable logistic and zero-inflated negative binomial regressions were used to assess the associations among cancer history/treatment status, gender, and employment outcomes (employment status and workdays lost to care for self or others). RESULTS: For men, employment did not differ significantly by cancer history/treatment status (on treatment: odds ratio [OR], 0.58; 95% confidence interval [CI], 0.33-1.02, off treatment: OR, 0.84; 95% CI, 0.62-1.14 vs. no cancer history). For women, employment was not significantly different when the spouse was on treatment for cancer compared to no cancer history (OR, 0.78; 95% CI, 0.33-1.86]) but was significantly increased for women whose spouse was off treatment (OR, 1.39; 95% CI, 1.05-1.84). Among employed participants, women whose spouse was on cancer treatment were nine times more likely to take days off work to provide care (OR, 9.52; 95% CI, 3.94-23.03) and took more than three times as many days off to care for others (OR, 3.21; 95% CI, 2.07-4.97) as men whose spouse had no cancer history. CONCLUSIONS: Wives of cancer survivors are at increased risk of work loss, with implications for their financial and psychological well-being. Employers, policymakers, and clinicians have opportunities to support working caregivers.

Diabetes mellitus in long-term survivors with colorectal, breast, or prostate cancer: Prevalence and prognosis. A population-based study.

BACKGROUND: Patients with cancer are at increased risk of diabetes mellitus (DM). Previous studies on the prevalence and prognostic impact of DM in cancer survivors were limited by small sample sizes or short follow-up times. We aimed to compare the patient-reported prevalence of DM in long-term cancer survivors (LTCS), who survived 5 years or more after cancer diagnosis, with that in cancer-free controls, and to estimate the mortality risk among LTCS according to DM status. METHODS: Our population-based cohort comprised 6952 LTCS diagnosed with breast, colorectal, or prostate cancer between 1994 and 2004, recruited in 2008-2011 (baseline), and followed until 2019. A total of 1828 cancer-free individuals served as controls. Multivariable logistic regression was used to compare the prevalence of DM in LTCS and controls, and according to covariates at baseline. Mortality among LTCS according to DM was assessed by Cox proportional hazards regression. RESULTS: A total of 962 (13.8%) LTCS at baseline reported DM. Prevalence of DM in LTCS was not higher than in cancer-free controls, both at baseline (odds ratio, 0.80; 95% CI, 0.66-0.97) and at follow-up (odds ratio, 0.83; 95% CI, 0.67-1.04). Prevalence of DM in LTCS was associated with cancer site, older age, lower education, higher socioeconomic deprivation, higher body mass index, physical inactivity, other comorbidities, and poorer prognosis (adjusted hazard ratio [all-cause mortality] = 1.29; 95% CI, 1.15-1.44). CONCLUSION: DM in LTCS is prevalent, but not higher than in cancer-free population controls. Cancer survivors with concurrent DM are at a potentially higher risk of death. PLAIN LANGUAGE SUMMARY: Cancer and diabetes mellitus (DM) are two serious threats to global health. In our study, prevalence of DM in long-term cancer survivors who survived 5 years or more after cancer diagnosis was not higher than in cancer-free controls. This should not be interpreted as an indication of a lower risk of DM in cancer survivors. Rather, it highlights the potentially poor prognosis in diabetic cancer survivors. Therefore, keeping a continuous satisfactory DM and hyperglycemia management is essential during long-term cancer survivorship.

It takes more than rainbows: Supporting sexual and gender minority patients with trauma-informed cancer care.

BACKGROUND/PURPOSE: The American Society of Clinical Oncology has called for an increased priority to improve cancer care for sexual and gender minority (SGM) populations because of heightened risk of receiving disparate treatment and having suboptimal experiences, including perceived discrimination. We demonstrate how integrating trauma-informed care (TIC) principles across the cancer continuum is a key strategy to improving care delivery and outcomes among SGM populations. METHOD: This empirically informed perspective expands on the concepts generated through the American Society of Clinical Oncology position statement and uses the Substance Abuse and Mental Health Services Association's "Four Rs" Toward Trauma Informed Care: Realize, Recognize, Response, and Resist Traumatization. RESULTS: Recommendations for each component of TIC include: (1) Realize: Implement SGM cultural humility training, including modules on SGM-specific trauma, discrimination, harassment, and violence; (2) Recognize: Routinely screen for emotional distress using methods to ensure privacy, and/or normalize mental health screenings to cancer patients; (3) Respond: Create and widely disseminate policies and patients' rights that prohibit discrimination and ensure access to gender-neutral clinical environments; and (4) Resist Traumatization: Establish and respond to quality metrics (e.g., standardized patients, patient satisfaction surveys) that are informed by a community advisory board with the purpose of ensuring and maintaining quality care. CONCLUSIONS AND IMPLICATIONS: Integrating TIC principles into cancer care for SGM populations is crucial to address disparities in treatment and clinical outcomes. Our recommendations offer practical approaches for oncology teams to implement TIC care and ensure equitable and inclusive cancer care for patients and their families.

Understanding racial differences in financial hardship among older adults surviving cancer.

BACKGROUND: Despite Medicare coverage, financial hardship is a prevalent issue among those diagnosed with cancer at age 65 years and older, particularly among those belonging to a racial or ethnic minority group. Sociodemographic, clinical, and area-level factors may mediate this relationship; however, no studies have assessed the extent to which these factors contribute to the racial/ethnic disparities in financial hardship. METHODS: Surveys assessing financial hardship were completed by 721 White (84%) or Black (16%) patients (aged 65 years and older) who were diagnosed with breast (34%), prostate (27%), lung (17%), or colorectal (14%) cancer or lymphoma (9%) at the University of Alabama at Birmingham between 2000 and 2019. Financial hardship included material, psychological, and behavioral domains. Nonlinear Blinder-Oaxaca effect decomposition methods were used to evaluate the extent to which individual and area-level factors contribute to racial disparities in financial hardship. RESULTS: Black patients reported lower income (65% vs. 34% earning <$50,000) and greater scores on the Area Deprivation Index (median, 93.0 vs. 55.0). Black patients reported significantly higher rates of overall (39% vs. 18%), material (29% vs. 11%), and psychological (27% vs. 11%) hardship compared with White patients. Overall, the observed characteristics explained 51% of racial differences in financial hardship among cancer survivors, primarily because of differences in income (23%) and area deprivation (11%). CONCLUSIONS: The current results identify primary contributors to racial disparities in financial hardship among older cancer survivors, which can be used to develop targeted interventions and allocate resources to those at greatest risk for financial hardship.

Risk of chronic health conditions in lesbian, gay, and bisexual survivors of adolescent and young adult cancers.

BACKGROUND: In the general population, individuals with minoritized sexual orientation and gender identity have a higher burden of chronic health conditions than heterosexual individuals. However, the extent to which sexual orientation is associated with excess burden of chronic conditions in adolescent and young adult cancer survivors (AYACS) is unknown. METHODS: Lesbian, gay, and bisexual (LGB) AYACSs, LGB individuals without a history of cancer, and heterosexual AYACSs were identified by self-reported data from the cross-sectional National Health Interview Survey (2013-2020). Socioeconomic factors and the prevalence of chronic health conditions were compared between groups using χ2 tests. Logistic regression methods were used to determine the odds of chronic conditions by socioeconomic factors within and between survivor and comparison groups. RESULTS: One hundred seventy LGB cancer survivors, 1700 LGB individuals without a history of cancer, and 1700 heterosexual cancer survivors were included. Compared with heterosexual survivors, LGB survivors were less likely to be married (p = .001) and more likely to have never been married (p < .001). LGB survivors were more likely to have incomes between 100% and 200% of the federal poverty level than LGB individuals without a history of cancer (p = .012) and heterosexual survivors (p = .021) and were less likely to report incomes >200% the federal poverty level. LGB survivors had higher odds of chronic health conditions than LGB individuals without a history of cancer (odds ratio, 2.45; p < .001) and heterosexual survivors (odds ratio, 2.16; p = .003). CONCLUSIONS: LGB AYACSs are at increased risk of having chronic health conditions compared with both LGB individuals without a history of cancer and heterosexual AYACSs.

Reproductive outcomes and reproductive health care utilization among male survivors of childhood cancer: A DCCSS-LATER study.

BACKGROUND: Treatment-related gonadal dysfunction leading to fertility problems is a frequently encountered late effect in childhood cancer survivors (CCSs). This study evaluated reproductive outcomes and reproductive health care utilization among male CCSs compared with male siblings. METHODS: A nationwide cohort study was conducted as part of the Dutch Childhood Cancer Survivor LATER study part 1, a questionnaire and linkage study. A questionnaire addressing reproductive outcomes and reproductive health care was completed by 1317 male CCSs and 407 male siblings. A total of 491 CCSs and 185 siblings had a previous or current desire for children and were included in this study. RESULTS: Fewer CCSs had biological children compared with siblings (65% vs. 88%; p < .001). The type of conception by men who fathered a child was comparable between CCSs and siblings (spontaneous conception of 90% of both groups; p = .86). The percentage of men who had consulted a reproductive specialist because of not siring a pregnancy was higher in CCSs compared with siblings (34% vs. 12%; p < .001). Following consultation, fewer CCSs underwent assisted reproductive techniques (ART) compared with siblings (41% vs. 77%; p = .001). After ART, fewer CCSs fathered a child compared with siblings (49% vs. 94%; p = .001). CONCLUSIONS: More male survivors consult a reproductive specialist, but fewer survivors undergo ART and father a child after ART compared with siblings. This insight is important for understanding potential problems faced by survivors regarding family planning and emphasizes the importance of collaboration between oncologists and reproductive specialists.

Social isolation, depression, and anxiety among young adult cancer survivors: The mediating role of social connectedness.

BACKGROUND: Social isolation and social connectedness are health determinants and aspects of social well-being with strong associations with psychological distress. This study evaluated relationships among social isolation, social connectedness, and psychological distress (i.e., depression, anxiety) over 1 year in young adult (YA) cancer survivors 18-39 years old. METHODS: Participants were YAs in a large cohort study that completed questionnaires every 2 months for 1 year. Social isolation, aspects of social connectedness (i.e., companionship, emotional support, instrumental support, and informational support), depression, and anxiety were assessed with Patient-Reported Outcomes Measurement Information System short form measures. Mixed-effect models were used to evaluate changes over time. Confirmatory factor analysis and multilevel structural equation modeling were used to define social connectedness as a latent construct and determine whether relationships between social isolation and psychological distress were mediated by social connectedness. RESULTS: Participants (N = 304) were mean (M) = 33.5 years old (SD = 4.7) and M = 4.5 years (SD = 3.5) post-initial cancer diagnosis. Most participants were female (67.4%) and non-Hispanic White (68.4%). Average scores for social well-being and psychological distress were within normative ranges and did not change (p values >.05). However, large proportions of participants reported at least mild social isolation (27%-30%), depressive symptoms (36%-37%), and symptoms of anxiety (49%-51%) at each time point. Across participants, more social isolation was related to less social connectedness (p values <.001), more depressive symptoms (p < .001), and more symptoms of anxiety (p < .001). Social connectedness mediated the relationship between social isolation and depression (p = .004), but not anxiety (p > .05). CONCLUSIONS: Social isolation and connectedness could be intervention targets for reducing depression among YA cancer survivors.

Sexual health in adult survivors of childhood cancer: A Project REACH study.

BACKGROUND: Sexual dysfunction is a significant complication of treatment for many adult-onset cancers. However, comparatively less is known about sexual dysfunction in adult childhood cancer survivors (CCSs). Research has been limited by the exclusion of specific cancers (e.g., central nervous system [CNS] tumors) and the lack of validated measures, which makes it difficult to understand the nature and prevalence of sexual dysfunction in CCSs. METHODS: A total of 249 adult CCSs (aged 18-65 years) enrolled in Project REACH, a prospective cohort study, and completed measures of physical and mental health, including sexual dysfunction. Participants scoring ≤19 on the Female Sexual Function Index 6 or ≤21 on the International Index of Erectile Function 5 were classified as experiencing sexual dysfunction. Analyses examined the relationships between sexual dysfunction and demographic, disease, treatment, and health variables. RESULTS: A total of 78 participants (32%) experienced clinically significant sexual dysfunction. In univariate analysis, sexual dysfunction was significantly associated with CNS tumor diagnosis (odds ratio [OR], 2.56) and surgery (OR, 1.96) as well as with health variables such as fatigue (OR, 3.00), poor sleep (OR, 2.84), pain (OR, 2.04), depression (OR, 2.64), poor physical health (OR, 2.45), and poor mental health (OR, 2.21). Adjusted analyses found that CNS tumor diagnosis (p = .001) and health variables (p = .025) contribute significantly to sexual dysfunction in CCSs. CONCLUSIONS: Approximately one third of adult CCSs report clinically significant sexual dysfunction, which underscores a significant screening and treatment need. However, because available measures were developed for survivors of adult cancers, research to create a sexual health measure specifically for adult CCSs is necessary to better identify the sexual health concerns of this vulnerable population.

Role of primary care in opioid prescribing for older head and neck cancer survivors.

BACKGROUND: Older head and neck cancer (HNC) survivors have concerning rates of potentially unsafe opioid prescribing. Identifying the specialties of opioid prescribers for HNC survivors is critical for targeting the settings for opioid safety interventions. This study hypothesized that oncology and surgery providers are primarily responsible for opioid prescriptions in the year after treatment but that primary care providers (PCPs) are increasingly involved in prescribing over time. METHODS: Using linked Surveillance, Epidemiology, and End Results-Medicare data, a retrospective analysis was conducted of adults aged >65 years diagnosed between 2014 and 2017 with stage I-III HNC and who had ≥6 months of treatment-free follow-up through 2019. Starting at treatment completion, opioid fills were assigned to a prescriber specialty: oncology, surgery, primary care, pain management, or other. Prescriber patterns were summarized for each year of follow-up. Multinomial logistic regression models captured the likelihood of opioids being prescribed by each specialty. RESULTS: Among 5135 HNC survivors, 2547 (50%) had ≥1 opioid fill (median, 2.1-year follow-up). PCPs prescribed 47% of all fills (42%-55% each year). PCPs prescribed opioids to 45% of survivors with ≥1 opioid fill, which was a greater share than other specialties. PCPs prescribed longer supplies of opioids (median, 20 days/fill; median, 30 days/year) than oncologists or surgeons. The likelihood of an opioid being prescribed by an oncology provider was four times lower than that of it being prescribed by a PCP. CONCLUSIONS: PCP involvement in opioid prescribing remains high throughout HNC survivorship. Interventions to improve the safety of opioid prescribing should target primary care, as is typical for opioid reduction efforts in the noncancer population.

Psychological distress and mental health care utilization among Black survivors of adolescent and young adult cancer.

BACKGROUND: Survivors of adolescent and young adult (AYA) cancer experience significant psychological distress and encounter barriers to accessing mental health care. Few studies have investigated racial/ethnic disparities in psychological health outcomes among AYA survivors, and none have compared outcomes within a racially minoritized population. METHODS: National Health Interview Survey data (2010-2018) were analyzed that identified non-Hispanic Black (hereafter, Black) survivors of AYA cancer and age- and sex-matched Black noncancer controls. Sociodemographic factors, chronic health conditions, modifiable behaviors (smoking and alcohol use), and psychological outcomes were assessed with χ2 tests. Logistic regression models, adjusted for survey weights, were used to evaluate the odds of psychological distress by cancer status after adjusting for covariates. Interactions between variables and cancer status were investigated. RESULTS: The study included 334 Black survivors of AYA cancer and 3340 Black controls. Compared to controls, survivors were more likely to report moderate/severe distress (odds ratio [OR], 1.64; p < .001), use mental health care (OR, 1.53; p = .027), report an inability to afford mental health care (OR, 3.82; p < .001), and use medication for anxiety and/or depression (OR, 2.16; p = .001). Forty-one percent of survivors reported moderate/severe distress, and only 15% used mental health care. Among survivors, ages 18-39 years (vs. 40-64 years) and current smoking (vs. never smoking) were associated with the presence of moderate/severe distress. Among survivors with distress, high poverty status was associated with reduced utilization of mental health care. CONCLUSIONS: A cancer diagnosis for a Black AYA is associated with greater psychological distress within an already vulnerable population.
