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.

"I couldn't connect the wires in my brain." Young adult cancer survivors' experience with cognitive functioning.

OBJECTIVE: There is a dearth of literature describing young adult (YA) cancer survivors' experiences with cancer-related cognitive impairment (CRCI). We aimed to elucidate CRCI among YA cancer survivors and identify potentially modifiable risk factors. METHODS: We conducted individual qualitative interviews with YA cancer survivors aged 18-30 years at study enrollment and used applied thematic analysis to identify themes across three topics (i.e., affected cognitive abilities, risk and protective factors influencing the impact of CRCI, and strategies for coping with CRCI). RESULTS: YA cancer survivors (N = 20) were, on average, 23 years old at diagnosis and 26 years old when interviewed. Diverse cancer types and treatments were represented; most participants (85%) had completed cancer treatment. Participants described experiences across three qualitative topics: (1) affected cognitive abilities (i.e., concentration and attention, prospective memory, and long-term memory), (2) Risk factors (i.e., fatigue, sleep problems, mood, stress/distractions, and social isolation) and protective factors (i.e., social support), and (3) coping strategies, including practical strategies that helped build self-efficacy (e.g., writing things down, reducing distractions), beneficial emotion-focused coping strategies (e.g., focus on health, faith/religion), strategies with mixed effects (i.e., apps/games, medications/supplements, and yoga), and "powering through" strategies that exacerbated stress. CONCLUSIONS: YA cancer survivors experience enduring cognitive difficulties after treatment. Specific concerns highlight the importance of attention and executive functioning impairments, long-term memory recall, and sensitivity to distractions. Future work is needed to improve assessment and treatment of CRCI among YA cancer survivors.

Patient reported outcomes and patient experiences of immune checkpoint modulators for advanced or recurrent melanoma: a mixed methods study.

PURPOSE: Little is known about late and long-term patient-reported outcomes (PROs) of immune checkpoint modulators (ICMs) outside clinical trials. We conducted a cross-sectional, mixed-methods study to describe long-term PROs among advanced melanoma patients who began standard of care treatment with ICMs at least 1 year previously. METHODS: All participants completed the Functional Assessment of Cancer Therapy-Immune Checkpoint Modulator (FACT-ICM), assessing 46 immune-related side effects on a 5-point Likert scale, and a subset completed individual interviews. Descriptive statistics were computed for quantitative data and applied thematic analysis was used to examine qualitative data. RESULTS: Participants (N = 80) had a mean age of 67 years, and the majority were male (66%), non-Hispanic White (96%), and college graduates (61%). Single-agent nivolumab was the most common first (47%) and current/recent ICM (64%). On the FACT-ICM, 98% of participants reported at least one side effect, and 78% reported moderate or severe side effects. The most common moderate or severe side effects were aching joints (43%) and fatigue (38%). In interviews (n = 20), we identified five themes regarding patients' longer-term experiences after ICMs: lasting fatigue or decline in functioning, minimal side effects, manageable thyroid and pituitary dysfunction, skin conditions can be difficult to manage, and treating the cancer is worth the side effects. CONCLUSIONS: Nearly all patients reported side effects of ICMs at least 1 year after starting treatment. Our findings suggest that ICM side effect screening and management-especially for aching joints and fatigue-are indicated during long-term care of people living with advanced melanoma.

Plasma levels of interleukin-6 mediate neurocognitive performance in older breast cancer survivors: The Thinking and Living With Cancer study.

BACKGROUND: Immune activation/inflammation markers (immune markers) were tested to explain differences in neurocognition among older breast cancer survivors versus noncancer controls. METHODS: Women >60 years old with primary breast cancer (stages 0-III) (n = 400) were assessed before systemic therapy with frequency-matched controls (n = 329) and followed annually to 60 months; blood was collected during annual assessments from 2016 to 2020. Neurocognition was measured by tests of attention, processing speed, and executive function (APE). Plasma levels of interleukin-6 (IL-6), IL-8, IL-10, tumor necrosis factor α (TNF-α), and interferon γ were determined using multiplex testing. Mixed linear models were used to compare results of immune marker levels by survivor/control group by time and by controlling for age, racial/ethnic group, cognitive reserve, and study site. Covariate-adjusted multilevel mediation analyses tested whether survivor/control group effects on cognition were explained by immune markers; secondary analyses examined the impact of additional covariates (e.g., comorbidity and obesity) on mediation effects. RESULTS: Participants were aged 60-90 years (mean, 67.7 years). Most survivors had stage I (60.9%) estrogen receptor-positive tumors (87.6%). Survivors had significantly higher IL-6 levels than controls before systemic therapy and at 12, 24, and 60 months (p ≤ .001-.014) but there were no differences for other markers. Survivors had lower adjusted APE scores than controls (p < .05). Levels of IL-6, IL-10, and TNF-α were related to APE, with IL-6 explaining part of the relationship between survivor/control group and APE (p = .01). The magnitude of this mediation effect decreased but remained significant (p = .047) after the consideration of additional covariates. CONCLUSIONS: Older breast cancer survivors had worse long-term neurocognitive performance than controls, and this relationship was explained in part by elevated IL-6.

An Examination of the Longitudinal Relationship Between Cognitive Function and Physical Activity Among Older Breast Cancer Survivors in the Thinking and Living With Cancer Study.

BACKGROUND: Older cancer survivors are at risk for cognitive decline. Physical activity can improve cognition, and better cognitive function may facilitate greater physical activity. PURPOSE: We examined the potential bidirectional relationship between cognitive function and physical activity in older breast cancer survivors and controls. METHODS: The sample included women with newly diagnosed, nonmetastatic breast cancer (n = 395) and women without cancer (n = 374) ages 60-98. Participants were recruited as part of a larger multisite study, assessed prior to systemic therapy, and followed yearly for 36 months. Attention, processing speed, and executive function was measured using six neuropsychological tests, self-reported cognitive function using the Perceived Cognitive Impairments subscale of the Functional Assessment of Cancer Therapy-Cognitive Function , and physical activity using the International Physical Activity Questionnaire-Short Form. Separate random intercepts cross-lagged panel models were used to examine the between- and within-person effects for survivors and controls, controlling for age, education, and study site. RESULTS: Survivors reported significantly less physical activity than controls at baseline (1,284.92 vs. 2,085.98 MET min/week, p < .05). When survivors reported higher activity, they simultaneously had better objective cognition at 12 months (ß = 0.24, p = .04) and reported better perceived cognition at 12 and 24 months (ß = 0.25, p = .03), but this relationship was not seen in controls. Cognition did not predict subsequent physical activity or vice versa in either group. CONCLUSIONS: Cognition and physical activity are cross-sectionally associated in survivors, but the expected prospective relationships were not found.

Physical activity may improve cognitive function for older cancer survivors; however, cognitive function may also affect the ability to organize oneself to be physically active. We examined this potential bidirectional relationship in a sample of 395 women with newly diagnosed, nonmetastatic breast cancer, and 374 noncancer controls. These women completed cognitive tests and surveys yearly for 36 months. Surveys included their subjective cognitive function and physical activity. We examined the relationships between cognitive function (both objective and subjective) and physical activity over time (baseline, 12, 24, and 36 months). We found that when cancer survivors reported higher physical activity, they had better objective cognitive function at 12 months, and they reported better subjective cognitive function at 12 and 24 months. However, physical activity did not predict cognitive function at later time points, and cognitive function did not predict physical activity at later time points. In controls, better subjective cognitive function was related to higher physical activity overall, but there were not relationships over time or at specific time points. This was an observational study; therefore, future research should consider the potential impact of cognitive function when older cancer survivors are attempting to increase their physical activity.

Metagenomics and chemotherapy-induced nausea: A roadmap for future research.

Uncontrolled chemotherapy-induced nausea and vomiting can reduce patients' quality of life and may result in premature discontinuation of chemotherapy. Although nausea and vomiting are commonly grouped together, research has shown that antiemetics are clinically effective against chemotherapy-induced vomiting (CIV) but less so against chemotherapy-induced nausea (CIN). Nausea remains a problem for up to 68% of patients who are prescribed guideline-consistent antiemetics. Despite the high prevalence of CIN, relatively little is known regarding its etiology independent of CIV. This review summarizes a metagenomics approach to the study and treatment of CIN with the goal of encouraging future research. Metagenomics focuses on genetic risk factors and encompasses both human (ie, host) and gut microbial genetic variation. Little work to date has focused on metagenomics as a putative biological mechanism of CIN. Metagenomics has the potential to be a powerful tool in advancing scientific understanding of CIN by identifying new biological pathways and intervention targets. The investigation of metagenomics in the context of well-established demographic, clinical, and patient-reported risk factors may help to identify patients at risk and facilitate the prevention and management of CIN.

Development and initial testing of TOGETHER-YA: an eHealth-delivered and group-based psychosocial intervention for young adult cancer survivors.

PURPOSE: This study aimed to (1) develop TOGETHER-YA, an e-Health-delivered and group-based health-related quality of life (HRQOL) intervention for young adult (YA) cancer survivors aged 18-39 (Part 1), and (2) determine its initial feasibility and acceptability in a single-arm pilot trial (Part 2). METHODS: TOGETHER-YA is a manualized, 10-week intervention for YA survivors that includes elements of relaxation training, cognitive-behavioral therapy, and health education. In Part 1, content was adapted from existing evidence-based interventions with feedback from YAs (N = 22) in four iterative focus groups. In Part 2, YA survivors (N = 11) participated in a single-arm pilot trial of TOGETHER-YA. Intervention groups were led by a trained facilitator over videoconference. Primary outcomes were feasibility (i.e., recruitment, session attendance, retention) and acceptability (i.e., participant satisfaction). RESULTS: Focus groups reacted positively to TOGETHER-YA and provided actionable recommendations for enhancing its relevance and acceptability, which were implemented. In initial testing, all feasibility and acceptability benchmarks were met; 58% of eligible YAs were recruited, participants attended M = 6 intervention sessions (SD = 3), and 82% of participants were retained post-intervention. On average, participants "agreed" to "strongly agreed" with positive statements about the weekly sessions and the overall program. CONCLUSION: TOGETHER-YA was developed in collaboration with YA cancer survivors and found to be feasible and acceptable in initial testing. TOGETHER-YA is the first HRQOL intervention for a broad range of YA survivors that is eHealth-delivered for convenience and group-based for peer support. Future large-scale trials should test its efficacy for improving HRQOL. TRIAL REGISTRATION: NCT05048316, September 17, 2021; NCT05054569, September 23, 2021.

Symptom burden among older breast cancer survivors: The Thinking and Living With Cancer (TLC) study.

BACKGROUND: Little is known about longitudinal symptom burden, its consequences for well-being, and whether lifestyle moderates the burden in older survivors. METHODS: The authors report on 36-month data from survivors aged ≥60 years with newly diagnosed, nonmetastatic breast cancer and noncancer controls recruited from August 2010 through June 2016. Symptom burden was measured as the sum of self-reported symptoms/diseases as follows: pain (yes or no), fatigue (on the Functional Assessment of Cancer Therapy [FACT]-Fatigue scale), cognitive (on the FACT-Cognitive scale), sleep problems (yes or no), depression (on the Center for Epidemiologic Studies Depression scale), anxiety (on the State-Trait Anxiety Inventory), and cardiac problems and neuropathy (yes or no). Well-being was measured using the FACT-General scale, with scores from 0 to 100. Lifestyle included smoking, alcohol use, body mass index, physical activity, and leisure activities. Mixed models assessed relations between treatment group (chemotherapy with or without hormone therapy, hormone therapy only, and controls) and symptom burden, lifestyle, and covariates. Separate models tested the effects of fluctuations in symptom burden and lifestyle on function. RESULTS: All groups reported high baseline symptoms, and levels remained high over time; differences between survivors and controls were most notable for cognitive and sleep problems, anxiety, and neuropathy. The adjusted burden score was highest among chemotherapy-exposed survivors, followed by hormone therapy-exposed survivors versus controls (P < .001). The burden score was related to physical, emotional, and functional well-being (eg, survivors with lower vs higher burden scores had 12.4-point higher physical well-being scores). The composite lifestyle score was not related to symptom burden or well-being, but physical activity was significantly associated with each outcome (P < .005). CONCLUSIONS: Cancer and its treatments are associated with a higher level of actionable symptoms and greater loss of well-being over time in older breast cancer survivors than in comparable noncancer populations, suggesting the need for surveillance and opportunities for intervention.

Cognitive function prior to systemic therapy and subsequent well-being in older breast cancer survivors: Longitudinal findings from the Thinking and Living with Cancer Study.

OBJECTIVE: To investigate the relationships between self-reported and objectively measured cognitive function prior to systemic therapy and subsequent well-being outcomes over 24 months in older breast cancer survivors. METHODS: Data were from 397 women aged 60 to 98 diagnosed with non-metastatic breast cancer in the Thinking and Living with Cancer Study recruited from 2010-2016. Cognitive function was measured at baseline (following surgery, prior to systemic therapy) using neuropsychological assessments of attention, processing speed, and executive function (APE), learning and memory (LM), and the self-reported FACT-Cog scale. Well-being was measured using the FACT-G functional, physical, social, and emotional well-being domain scales at baseline and 12 and 24 months later, scaled from 0 (low) to 100 (high). Linear mixed-effects models assessed the relationships between each of baseline APE, LM, and FACT-Cog quartiles with well-being scores over 24 months, adjusted for confounding variables. RESULTS: At baseline, older survivors in the lowest APE, LM, and FACT-Cog score quartiles experienced poorer global well-being than those in the highest quartiles. At 24 months, older survivors tended to improve in well-being, and there were no differences according to baseline APE or LM scores. At 24 months, mean global well-being was 80.3 (95% CI: 76.2-84.3) among those in the lowest vs 86.6 (95% CI: 83.1-90.1) in the highest FACT-cog quartile, a clinically meaningful difference of 6.3 points (95% CI: 1.5-11.1). CONCLUSIONS: Among older breast cancer survivors, self-reported, but not objective cognitive impairments, were associated with lower global well-being over the first 2 years of survivorship.

Sleep disturbance and neurocognitive outcomes in older patients with breast cancer: Interaction with genotype.

BACKGROUND: Sleep disturbance and genetic profile are risks for cognitive decline in noncancer populations, yet their role in cancer-related cognitive problems remains understudied. This study examined whether sleep disturbance was associated with worse neurocognitive outcomes in breast cancer survivors and whether sleep effects on cognition varied by genotype. METHODS: Newly diagnosed female patients (n = 319) who were 60 years old or older and had stage 0 to III breast cancer were recruited from August 2010 to December 2015. Assessments were performed before systemic therapy and 12 and 24 months later. Neuropsychological testing measured attention, processing speed, executive function, learning, and memory; self-perceived cognitive functioning was also assessed. Sleep disturbance was defined by self-report of routine poor or restless sleep. Genotyping included APOE, BDNF, and COMT polymorphisms. Random effects fluctuation models tested associations of between-person and within-person differences in sleep, genotype, and sleep-genotype interactions and cognition and controlled for age, reading level, race, site, and treatment. RESULTS: One-third of the patients reported sleep disturbances at each time point. There was a sleep-APOE ε4 interaction (P = .001) in which patients with the APOE ε4 allele and sleep disturbances had significantly lower learning and memory scores than those who were APOE ε4-negative and without sleep disturbances. There was also a sleep disturbance-COMT genotype interaction (P = .02) in which COMT Val carriers with sleep disturbances had lower perceived cognition than noncarriers. CONCLUSIONS: Sleep disturbance was common and was associated with worse cognitive performance in older breast cancer survivors, especially those with a genetic risk for cognitive decline. Survivorship care should include sleep assessments and interventions to address sleep problems.

Metastatic breast cancer patients' expectations and priorities for symptom improvement.

PURPOSE: Little research has examined cancer patients' expectations, goals, and priorities for symptom improvement. Thus, we examined these outcomes in metastatic breast cancer patients to provide patients' perspectives on clinically meaningful symptom improvement and priorities for symptom management. METHODS: Eighty women with metastatic breast cancer participated in a survey with measures of comorbidity, functional status, engagement in roles and activities, distress, quality of life, and the modified Patient-Centered Outcomes Questionnaire that focused on 10 common symptoms in cancer patients. RESULTS: On average, patients reported low to moderate severity across the 10 symptoms and expected symptom treatment to be successful. Patients indicated that a 49% reduction in fatigue, 48% reduction in thinking problems, and 43% reduction in sleep problems would represent successful symptom treatment. Cluster analysis based on ratings of the importance of symptom improvement yielded three clusters of patients: (1) those who rated thinking problems, sleep problems, and fatigue as highly important, (2) those who rated pain as moderately important, and (3) those who rated all symptoms as highly important. The first patient cluster differed from other subgroups in severity of thinking problems and education. CONCLUSIONS: Metastatic breast cancer patients report differing symptom treatment priorities and criteria for treatment success across symptoms. Considering cancer patients' perspectives on clinically meaningful symptom improvement and priorities for symptom management will ensure that treatment is consistent with their values and goals.

Symptom experiences in metastatic breast cancer patients: relationships to activity engagement, value-based living, and psychological inflexibility.

OBJECTIVE: This study examined symptom-based subgroups of metastatic breast cancer (MBC) patients and the extent to which they differed across key constructs of acceptance and commitment therapy (ACT). METHODS: Eighty women with MBC completed self-report surveys assessing 10 common symptoms and several ACT variables (ie, activity engagement, psychological inflexibility, value obstruction, and value progress) during a single time point. RESULTS: A cluster analysis yielded 3 patient subgroups: low symptoms, low-moderate symptoms, and moderate-high symptoms. Relative to the subgroup with low symptoms, the other subgroups reported less activity engagement. In addition, compared with patients with low symptoms, the subgroup with moderate-high symptoms reported greater psychological inflexibility (ie, avoidance of unwanted internal experiences) and greater difficulty living consistently with their values. CONCLUSIONS: Women with MBC show heterogeneity in their symptom profiles, and those with higher symptom burden are more likely to disengage from valued activities and avoid unwanted experiences (eg, thoughts, feelings, and bodily sensations). Findings are largely consistent with the ACT model and provide strong justification for testing ACT to address symptom interference in MBC patients.

Effects of diet and exercise on weight-related outcomes for breast cancer survivors and their adult daughters: an analysis of the DAMES trial.

PURPOSE: Few trials have aimed to promote diet and exercise behaviors in both cancer survivors and their family members and examine their associations with weight-related outcomes. We conducted a secondary analysis to examine associations between change in diet and exercise behaviors and weight-related outcomes for overweight breast cancer survivors and their overweight adult daughters in the Daughters And MothErS Against Breast Cancer (DAMES) randomized trial. METHODS: The DAMES trial assessed the impact of two iteratively tailored, mailed print diet and exercise interventions against standard brochures over a 12-month period. This analysis examined change in diet and exercise behaviors and weight-related variables from baseline to post-intervention for the 50 breast cancer survivors and their adult daughters randomized to the intervention arms. To reduce the potential for type II error in this pilot, p values <0.10 were considered statistically significant. RESULTS: For mothers, change in diet quality was uniquely related to change in BMI (ß = -0.12, p = 0.082), weight (ß = -0.12, p = 0.060), and waist circumference (ß = -0.38, p = 0.001), whereas change in caloric intake was related to waist circumference (ß = 0.21, p = 0.002). For daughters, change in caloric intake was related to change in waist circumference (ß = 0.12, p = 0.055). However, change in diet quality was not associated with weight-related outcomes in daughters. Additionally, change in exercise was not associated with weight-related outcomes in mothers or daughters. CONCLUSIONS: Findings support mail-based and other tailored interventions for weight loss in this population, with an emphasis on diet quality for breast cancer survivors and caloric intake for their adult daughters.

The Modified Telephone Interview for Cognitive Status is More Predictive of Memory Abilities Than the Mini-Mental State Examination.

Although not as popular as the Mini-Mental State Examination (MMSE), the modified Telephone Interview for Cognitive Status (mTICS) has some distinct advantages when screening cognitive functioning in older adults. The current study compared these 2 cognitive screening measures in their ability to predict performance on a memory composite (ie, delayed recall of verbal and visual information) in a cohort of 121 community-dwelling older adults, both at baseline and after 1 year. Both the MMSE and the mTICS significantly correlated with the memory composite at baseline (r's of .41 and .62, respectively) and at 1 year (r's of .36 and .50, respectively). At baseline, stepwise linear regression indicated that the mTICS and gender best predicted the memory composite score (R (2) = .45, P < .001), and the MMSE and other demographic variables did not significantly improve the prediction. At 1 year, the results were very similar. Despite its lesser popularity, the mTICS may be a more attractive option when screening for cognitive abilities in this age range.

The Efficacy of Ketamine for Acute and Chronic Pain in Patients with Cancer: A Systematic Review of Randomized Controlled Trials.

Managing cancer-related pain poses significant challenges, prompting research into alternative approaches such as ketamine. This systematic review aims to analyze and summarize the impact of ketamine as an adjuvant to opioid therapy for cancer-related pain. We conducted a literature review in MEDLINE, EMBASE, and Scopus from 1 January 1982 to 20 October 2023. Abstracts were screened against inclusion criteria, and eligible studies underwent a full-text review. Data was extracted from the included studies, and a framework analysis approach summarized the evidence regarding ketamine's use in patients with cancer. A total of 21 randomized clinical trials were included, and the quality of all the included studies was good or fair. Significant improvements in pain scores and reduced morphine consumption were consistently observed with intravenous ketamine administration for postoperative pain control, particularly when combined with other analgesics such as morphine. Ketamine was less effective when used as an analgesic for chronic pain management, with several studies on neuropathic pain or chemotherapy-induced neuropathy finding minimal significant effect on reduction of pain scores or morphine requirements. The efficacy of ketamine in pain management appears to depend on factors such as dosage, route of administration, and patient population.

The efficacy and safety of ketamine for depression in patients with cancer: A systematic review.

Background: Management of depression in the oncology population includes supportive psychotherapeutic interventions with or without psychotropic medication, which take time to demonstrate effectiveness. Fast-acting interventions, like ketamine, can provide a rapid antidepressant effect; however, there has been limited research on effects of ketamine among cancer patients. The objective of this review is to provide an overview of research on the efficacy and safety of ketamine on depression in patients with cancer. Methods: We reviewed the published literature in MEDLINE® (via PubMed®), EMBASE, and Scopus from 1 January 1982 to 20 October 2022. We screened the retrieved abstracts against inclusion criteria and conducted a full-text review of eligible studies. Following extraction of data from included studies, we used a framework analysis approach to summarize the evidence on using ketamine in patients with cancer. Results: All 5 included studies were randomized clinical trials conducted in inpatient settings in China. In all included studies ketamine was administered intravenously. Three studies used only racemic ketamine, and two studies used both S-ketamine and racemic ketamine. All included studies reported ketamine a tolerable and effective drug to control depression symptoms. Conclusion: Included studies showed administration of sub-anesthesia ketamine significantly improves postoperative depression among patients with cancer.

Physical Activity and Cognition: Longitudinal findings from the Thinking and Living with Cancer Study.

BACKGROUND: Physical activity can improve cognition; however, little is known regarding the relationships between longitudinal objectively-measured physical activity, cognition, and inflammation in older breast cancer survivors. METHODS: Older (≥60 yrs) breast cancer survivors (n = 216) and frequency-matched non-cancer controls (n = 216) were assessed at baseline (pre-systemic therapy for survivors) and annually for up to five years. Assessments included hip-worn ActiGraphs worn for seven days, neuropsychological tests, the Functional Assessment of Cancer Therapy-Cognitive Function Perceived Cognitive Impairment (FACT-Cog PCI) subscale, and circulating levels of C-reactive protein (CRP) and interleukin-6 (IL-6). Data were analyzed using linear mixed-effect, random-effect contemporaneous fluctuation, and multi-level mediation models, considering covariates; p < .05 (two-sided) was considered significant. RESULTS: Survivors had fewer minutes of moderate-to-vigorous physical activity (MVPA) than controls at 36-, 48-, and 60-month time points (p < .03). Fewer survivors met Aerobic Physical Activity Guidelines at 36 months than controls (17.7% vs 33.0%, p = .030). When Guidelines were met (vs not), FACT-Cog PCI scores were 2.1 ± 1.0 (p = .034) points higher. Higher MVPA and meeting Aerobic Guidelines were not related to objective neuropsychological performance. MVPA was inversely associated with CRP and IL-6 (p < .001), but inflammation did not mediate physical activity effects on perceived cognition. CONCLUSIONS: Older breast cancer survivors were less physically active than older non-cancer controls, especially farther from baseline. Meeting Aerobic Guidelines was associated with better perceived cognition in survivors. Survivorship care should consider physical activity monitoring and referral to rehabilitation and supervised exercise programs to promote physical activity and improve recovery in older survivors.

Alzheimer disease-related biomarkers and cancer-related cognitive decline: the Thinking and Living with Cancer study.

PURPOSE: We evaluated whether plasma Alzheimer disease (AD)-related biomarkers were associated with cancer-related cognitive decline among older breast cancer survivors. METHODS: We included survivors aged 60-90 years with primary stage 0-III breast cancers (n = 236) and frequency-matched noncancer control paricipant (n = 154) who passed a cognitive screen and had banked plasma specimens. Participants were assessed at baseline (presystemic therapy) and annually for up to 60 months. Cognition was measured using tests of attention, processing speed, and executive function and learning and memory; perceived cognition was measured by the Functional Assessment of Cancer Therapy-Cognitive Function v3 Perceived Cognitive Impairments. Baseline plasma neurofilament light, glial fibrillary acidic protein, ß-amyloid 42 and 40 and phosphorylated tau 181 were assayed using single molecule arrays. Mixed models tested associations between cognition and baseline AD biomarkers, time, group (survivor vs control participant), and their 2- and 3-way interactions, controlling for age, race, Wide Range 4 Achievement Test Word Reading score, comorbidity, and body mass index; 2-sided P values of .05 were considered statistically significant. RESULTS: There were no group differences in baseline AD-related biomarkers except survivors had higher baseline neurofilament light levels than control participants (P = .013). Survivors had lower adjusted longitudinal attention, processing speed, and executive function than control participants starting from baseline and continuing over time (P ≤ .002). However, baseline AD-related biomarker levels were not independently associated with adjusted cognition over time, except control participants had lower attention, processing speed, and executive function scores with higher glial fibrillary acidic protein levels (P = .008). CONCLUSION: The results do not support a relationship between baseline AD-related biomarkers and cancer-related cognitive decline. Further investigation is warranted to confirm the findings, test effects of longitudinal changes in AD-related biomarkers, and examine other mechanisms and factors affecting cognition presystemic therapy.

Relationships among Inflammatory Biomarkers and Objectively Assessed Physical Activity and Sleep during and after Chemotherapy for Gynecologic Malignancies.

Little is known regarding associations between inflammatory biomarkers and objectively measured physical activity and sleep during and after chemotherapy for gynecologic cancer; thus, we conducted a longitudinal study to address this gap. Women with gynecologic cancer (patients) and non-cancer controls (controls) completed assessments before chemotherapy cycles 1, 3, and 6 (controls assessed contemporaneously), as well as at 6- and 12-month follow-ups. Physical activity and sleep were measured using wrist-worn actigraphs and sleep diaries, and blood was drawn to quantify circulating levels of inflammatory markers. Linear and quadratic random-effects mixed models and random-effects fluctuation mixed models were used to examine physical activity and sleep over time, as well as the associations with inflammatory biomarkers. On average, patients (n = 97) and controls (n = 104) were 62 and 58 years old, respectively. Compared to controls, patients were less active, more sedentary, had more time awake after sleep onset, and had lower sleep efficiency (p-values < 0.05). Across groups, higher levels of TNF-α were associated with more sedentary time and less efficient sleep (p-values ≤ 0.05). Higher levels of IL-1ß, TNF-α, and IL-6 were associated with lower levels of light physical activity (p-values < 0.05). Associations between inflammatory biomarkers, physical activity, and sleep did not differ between patients and controls. Given these results, we speculate that inflammation may contribute to less physical activity and more sleep problems that persist even 12 months after completing chemotherapy.

Oncology Providers' and Professionals' Experiences With Suicide Risk Screening Among Patients With Head and Neck Cancer: A Qualitative Study.

PURPOSE: There has been limited study of the implementation of suicide risk screening for patients with head and neck cancer (HNC) as a part of routine care. To address this gap, this study assessed oncology providers' and professionals' perspectives about barriers and facilitators of implementing a suicide risk screening among patients with HNC. MATERIALS AND METHODS: All patients with HNC with an in-person visit completed a suicide risk screening on an electronic tablet. Patients reporting passive death wish were then screened for active suicidal ideation and referred for appropriate intervention. Interviews were conducted with 25 oncology providers and professionals who played a key role in implementation including nurses, medical assistants, patient access representatives, advanced practice providers, physicians, social workers, and informatics staff. The interview guide was based on the Consolidated Framework for Implementation Research. Interviews were transcribed and analyzed for themes. RESULTS: Participants identified multilevel implementation barriers, such as intervention level (eg, patient difficulty with using a tablet), process level (eg, limited nursing engagement), organizational level (eg, limited clinic Wi-Fi connectivity), and individual level (eg, low clinician self-efficacy for interpreting and acting upon patient-reported outcome scores). Participants noted facilitators, such as effective care coordination across nursing and social work staff and the opportunity for patients to be screened multiple times. Participants recommended strengthening patient and clinician education and providing patients with other modalities for data entry (eg, desktop computer in the waiting room). CONCLUSION: Participants identified important intervention modifications that may be needed to optimize suicide risk screening in cancer care settings.
