Management of Fatigue in Adult Survivors of Cancer: ASCO-Society for Integrative Oncology Guideline Update.

PURPOSE: To update the ASCO guideline on the management of cancer-related fatigue (CRF) in adult survivors of cancer. METHODS: A multidisciplinary panel of medical oncology, geriatric oncology, internal medicine, psychology, psychiatry, exercise oncology, integrative medicine, behavioral oncology, nursing, and advocacy experts was convened. Guideline development involved a systematic literature review of randomized controlled trials (RCTs) published in 2013-2023. RESULTS: The evidence base consisted of 113 RCTs. Exercise, cognitive behavioral therapy (CBT), and mindfulness-based programs led to improvements in CRF both during and after the completion of cancer treatment. Tai chi, qigong, and American ginseng showed benefits during treatment, whereas yoga, acupressure, and moxibustion helped to manage CRF after completion of treatment. Use of other dietary supplements did not improve CRF during or after cancer treatment. In patients at the end of life, CBT and corticosteroids showed benefits. Certainty and quality of evidence were low to moderate for CRF management interventions. RECOMMENDATIONS: Clinicians should recommend exercise, CBT, mindfulness-based programs, and tai chi or qigong to reduce the severity of fatigue during cancer treatment. Psychoeducation and American ginseng may be recommended in adults undergoing cancer treatment. For survivors after completion of treatment, clinicians should recommend exercise, CBT, and mindfulness-based programs; in particular, CBT and mindfulness-based programs have shown efficacy for managing moderate to severe fatigue after treatment. Yoga, acupressure, and moxibustion may also be recommended. Patients at the end of life may be offered CBT and corticosteroids. Clinicians should not recommend L-carnitine, antidepressants, wakefulness agents, or routinely recommend psychostimulants to manage symptoms of CRF. There is insufficient evidence to make recommendations for or against other psychosocial, integrative, or pharmacological interventions for the management of fatigue.Additional information is available at www.asco.org/survivorship-guidelines.

Prevalence and Cancer-Specific Patterns of Functional Disability Among US Cancer Survivors, 2017-2022.

PURPOSE: To examine the prevalence and cancer-specific patterns of functional disabilities among US cancer survivors. METHODS: Data from 47,768 cancer survivors and 2,432,754 noncancer adults age 18 years and older from the 2017 to 2022 Behavioral Risk Factor Surveillance System were analyzed. Functional disabilities assessed included mobility disability (ie, serious difficulty walking or climbing stairs) and self-care disability (ie, self-reported difficulty dressing or bathing). Multivariable logistic regression models were used to assess the associations between functional disabilities and sociodemographic, lifestyle, and health-related factors. RESULTS: Cancer survivors tended to be older and non-Hispanic White than noncancer adults. The prevalence of mobility disability (27.9% v 13.4%) and self-care disability (7.4% v 3.8%) were higher among cancer survivors compared with noncancer adults. After multivariable adjustments, cancer survivors were more likely to report mobility (odds ratio [OR], 1.21 [95% CI, 1.16 to 1.26]) and self-care (OR, 1.19 [95% CI, 1.10 to 1.29]) disability than noncancer adults. The prevalence of mobility (34.9% v 26.3%) and self-care disability (9.8% v 6.7%) was higher in cancer survivors who were receiving active cancer treatment than in those who had completed cancer treatment. Higher prevalence of mobility and self-care disabilities was observed in cancer survivors who were racial/ethnic minorities and with higher BMI, low physical activity, lower levels of education and/or income, comorbidities, and those experiencing cancer/treatment-related pain. Patterns of mobility and self-care disabilities varied across cancer types. CONCLUSION: Over a quarter of US cancer survivors reported mobility disability, and nearly 10% reported self-care disability, with patterns varying across cancer types and treatment status. Racial/ethnic minorities, along with underserved groups and individuals with unhealthy lifestyles or comorbidities, were notably more affected by functional disabilities, underscoring the need for targeted disability prevention efforts.

Improving lifestyle behaviors during chemotherapy for breast cancer: The Lifestyle, Exercise, and Nutrition Early After Diagnosis (LEANer) Trial.

BACKGROUND: Little is known about improving physical activity (PA) and diet during and after chemotherapy for breast cancer. This secondary analysis examines changes in PA and diet quality during a yearlong intervention for patients with breast cancer undergoing chemotherapy and evaluates factors associated with these changes. METHODS: Newly diagnosed patients with breast cancer (N = 173) undergoing chemotherapy were randomized to a year-long nutrition and exercise intervention (n = 87) or usual care (UC, n = 86). Mixed models compared 1-year changes in PA and diet quality via the Healthy Eating Index (HEI)-2015 by study arm. Among the intervention group, baseline factors associated with change in PA and diet were assessed with multivariable linear and logistic regression. RESULTS: At 1 year, compared with UC, the intervention arm increased PA more (mean difference = 136.1 minutes/week; 95% CI, 90.2-182.0), participated in more strength training (56% vs. 15%; p < .001), and had suggestive improvements in HEI-2015 (mean difference = 2.5; 95% CI, -0.3 to 5.3; p = .08). In the intervention arm, lower fatigue was associated with improved PA (p = .04) and higher education was associated with improved HEI-2015 (p = .001) at 1 year. Higher HEI-2015 (p = .04) and married/living with someone (p = .05) were associated with higher odds of participating in strength training at 1 year. CONCLUSIONS: This year-long lifestyle intervention for patients with breast cancer undergoing chemotherapy resulted in increases in PA and suggestive improvements in diet quality. Behavior change was associated with baseline fatigue, diet quality, education, and married/living with someone. Addressing these factors in interventions may improve uptake of lifestyle behaviors in trials during and after chemotherapy.

Association of N-terminal pro-brain natriuretic peptide with survival among US cancer survivors.

BACKGROUND: N-terminal pro-brain natriuretic peptide (NT-proBNP) is a cardiac biomarker associated with the risk of heart failure and death in the general population, but it has not been explored in cancer survivors. METHODS: Using a US nationally representative sample of adults 20 years of age and older from the National Health and Nutrition Examination Survey from 1999 to 2004, this study compared NT-proBNP levels between adults without cancer (n = 12 574) and adult cancer survivors (n = 787). It examined the association of NT-proBNP with all-cause and cause-specific mortality among cancer survivors. RESULTS: Cancer survivors had higher NT-proBNP levels than adults without cancer (median [interquartile range] = 125.4 pg/mL [52.4-286.0] vs 43.2 pg/mL [20.3-95.0]). In particular, survivors of breast, prostate, and colorectal cancers had higher NT-proBNP levels than adults without cancer (multivariable-adjusted P < .05). In total, 471 survivors died (141 from cancer; 95 from cardiac disease) during a median follow-up period of 13.4 years (9393 person-years). Among cancer survivors, higher NT-proBNP levels were statistically associated with increased risks of all-cause death (hazard ratio [HR] = 1.31, 95% confidence interval [CI] = 1.18 to 1.46) and cardiac death (HR = 1.55, 95% CI = 1.21 to 2.00) but not with death from cancer (HR = 1.10, 95% CI = 0.92 to 1.32]). Higher NT-proBNP levels were associated with elevated overall mortality in survivors of prostate cancer (HR = 1.49, 95% CI = 1.22 to 1.81) and colorectal cancer (HR = 1.78, 95% CI = 1.00 to 3.16) (P = .169 for interaction). Nonlinear dose-response relationships were observed between NT-proBNP and mortality, with statistically significant relationships emerging above 125 pg/mL. CONCLUSIONS: Cancer survivors had higher NT-proBNP levels than adults without cancer, and elevated NT-proBNP levels were associated with higher risks of all-cause and cardiac mortality in cancer survivors.

Dietary and serum advanced glycation end-products and clinical outcomes in breast cancer.

One in five women with breast cancer will relapse despite ideal treatment. Body weight and physical activity are strongly associated with recurrence risk, thus lifestyle modification is an attractive strategy to improve prognosis. Trials of dietary modification in breast cancer are promising but the role of specific diets is unclear, as is whether high-quality diet without weight loss can impact prognosis. Advanced glycation end-products (AGEs) are compounds produced in the body during sugar metabolism. Exogenous AGEs, such as those found in food, combined with endogenous AGEs, make up the total body AGE load. AGEs deposit in tissues over time impacting cell signaling pathways and altering protein functions. AGEs can be measured or estimated in the diet and measured in blood through their metabolites. Studies demonstrate an association between AGEs and breast cancer risk and prognosis. Here, we review the clinical data on dietary and serum AGEs in breast cancer.

Exploring anxiety as an influencing factor of the impact of exercise and mind-body prehabilitation on cognitive functioning among women undergoing breast cancer surgery.

OBJECTIVE: The purpose of this secondary analysis was to describe the prevalence of anxiety, depression, and perceived stress among women newly diagnosed with breast cancer and the impact of baseline and changes in anxiety on cognitive functioning following exercise and mind-body prehabilitation interventions. METHODS: The sample consisted of 49 women with newly diagnosed breast cancer (stages I-III) who planned to undergo breast cancer surgery at two academic cancer centers. Participants were randomized to receive an exercise or mind-body prehabilitation intervention between the time of diagnosis and breast cancer surgery. Participants completed self-report measures of anxiety, depression (HADS), perceived stress, and cognitive functioning (EORTC-QLQ-C30) at study enrollment and prior to surgery (post-intervention). The relationships between change in cognitive functioning and change in anxiety among all participants were estimated using linear regression modeling. RESULTS: A significant proportion of women with newly diagnosed breast cancer had clinically significant anxiety (34.0%). Greater anxiety was moderately associated with worse cognitive functioning (r = -0.33) at baseline. Linear modeling found that changes in cognitive functioning and anxiety were inversely related: Each one-unit decrease in anxiety was associated with a two-unit improvement in cognitive function (p = .06). CONCLUSIONS: Anxiety was common in women with newly diagnosed breast cancer and was related to worse cognitive functioning. Assessment of anxiety at the time of diagnosis may allow for earlier anxiety management and subsequent improvement in cognitive functioning.

Fertility concerns and treatment decision-making among national sample of young women with breast cancer.

BACKGROUND: Diagnosis of breast cancer in young women has been shown to affect their decision-making with regard to fertility and family planning. Limited data are available from populations across the U.S. regarding this issue; thus, we sought to describe fertility concerns and efforts to preserve fertility in a national clinical trial population of young breast cancer patients. METHODS: The young and strong study was a cluster-randomized controlled trial testing an intervention program for young women with breast cancer. Patients were surveyed within 3 months after diagnosis and at 3, 6, and 12 months after. Surveys asked about sociodemographics, psychosocial domains, fertility concerns, and fertility preservation strategies. Univariable and multivariable models were used to investigate sociodemographic, clinical, and psychosocial predictors of fertility concerns. RESULTS: Of 467 women from 54 clinical sites across the U.S. (14 academic, 40 community), 419 were evaluable regarding fertility concerns. Median age was 40 years (range 22-45), 11% were Black, 6% Hispanic, and 75% had children. Tumor stage was I (35%), II (51%), or III (14%); 82% received chemotherapy. At time of the treatment decision, 133 (32%) participants had fertility concerns, among whom 47% indicated this affected their treatment decisions. Sixty percent of participants reported having discussed fertility with their physician. Twenty percent of those with fertility concerns used fertility preservation strategies. History of difficulty becoming pregnant and younger age were associated with higher odds of fertility concerns in multivariable modeling. CONCLUSION: Many young women with newly diagnosed breast cancer are concerned about fertility in a way that impacts their treatment decisions. Concerns were discussed, but few used fertility preservation strategies. These findings have implications for counseling young patients.

Well-Being Parameters and Intention to Leave Current Institution Among Academic Physicians.

Importance: Physician turnover interrupts care delivery and creates health care system financial burden. Objective: To describe the prevalence of burnout, professional fulfillment, and intention to leave (ITL) among physicians at academic-affiliated health care systems and identify institutional and individual factors associated with ITL. Design, Setting, and Participants: This cross-sectional study administered a survey to 37 511 attending-level medical specialists at 15 academic medical institutions participating in the Healthcare Professional Well-Being Academic Consortium. Data were collected from October 2019 to July 2021. Statistical analysis was performed from May 2022 to March 2023. Exposures: Hypothesized institutional and individual determinants of occupational well-being. Main Outcomes and Measures: The main outcome was ITL, defined as having at least a moderate intention (a score of 2 on a 0-4 scale) to leave one's institution within the next 2 years. Additional outcomes included burnout and professional fulfillment, defined using published Professional Fulfillment Index cut points. Results: Of 18 719 academic physician survey respondents (8381 [44.8%] male; 2388 [12.8%] Asian, 10 599 [56.6%] White, 1039 [5.6%] other race, 4693 [25.1%] unknown race; 294 [1.6%] Hispanic or Latina/Latino/Latinx), 6903 of 18 217 (37.9%) met criteria for burnout and 7301 of 18 571 (39.3%) for professional fulfillment; 5177 of 15 890 (32.6%) reported moderate or greater ITL. Burnout, professional fulfillment, and ITL varied across specialties. After adjusting for demographics, each 1-point increase (range 0-10) in burnout was directly associated with ITL (odds ratio [OR], 1.52 [95% CI, 1.49-1.55])c, and each 1-point increase in professional fulfillment was inversely associated with ITL (OR, 0.64 [95% CI, 0.63-0.65]). After adjusting for demographics, burnout, and professional fulfillment, each 1-point increase (range 0-10) in supportive leadership behaviors (OR, 0.83 [95% CI, 0.82-0.84]), peer support (OR, 0.93 [95% CI, 0.91-0.95]), personal-organizational values alignment (OR, 0.81 [95% CI, 0.80-0.82]), perceived gratitude (OR, 0.95 [95% CI, 0.92-0.97]), COVID-19 organizational support (OR, 0.88 [95% CI, 0.85-0.91]), and electronic health record helpfulness (OR, 0.95 [95% CI, 0.93-0.97]) were inversely associated with ITL, whereas each 1-point increase (range 0-10) in depression (OR, 1.08 [95% CI, 1.05-1.10]) and negative impact of work on personal relationships (OR, 1.09 [1.07-1.11]) were directly associated with ITL. Conclusions and Relevance: In this cross-sectional study of academic physicians, 32.6% indicated moderate or higher ITL within 2 years. Burnout, lack of professional fulfillment, and other well-being factors were associated with ITL, suggesting the need for a comprehensive approach to reduce physician turnover.

Randomized Trial of Exercise and Nutrition on Chemotherapy Completion and Pathologic Complete Response in Women With Breast Cancer: The Lifestyle, Exercise, and Nutrition Early After Diagnosis Study.

PURPOSE: Successful completion of chemotherapy is critical to improve breast cancer outcomes. Relative dose intensity (RDI), defined as the ratio of chemotherapy delivered to prescribed, is a measure of chemotherapy completion and is associated with cancer mortality. The effect of exercise and eating a healthy diet on RDI is unknown. We conducted a randomized trial of an exercise and nutrition intervention on RDI and pathologic complete response (pCR) in women diagnosed with breast cancer initiating chemotherapy. METHODS: One hundred seventy-three women with stage I-III breast cancer were randomly assigned to usual care (UC; n = 86) or a home-based exercise and nutrition intervention with counseling sessions delivered by oncology-certified registered dietitians (n = 87). Chemotherapy dose adjustments and delays and pCR were abstracted from electronic medical records. T-tests and chi-square tests were used to examine the effect of the intervention versus UC on RDI and pCR. RESULTS: Participants randomly assigned to intervention had greater improvements in exercise and diet quality compared with UC (P < .05). RDI was 92.9% ± 12.1% and 93.6% ± 11.1% for intervention and UC, respectively (P = .69); the proportion of patients in the intervention versus UC who achieved ≥85% RDI was 81% and 85%, respectively (P = .44). The proportion of patients who had at least one dose reduction and/or delay was 38% intervention and 36% UC (P = .80). Among 72 women who received neoadjuvant chemotherapy, women randomly assigned to intervention were more likely to have a pCR than those randomly assigned to UC (53% v 28%; P = .037). CONCLUSION: Although a diet and exercise intervention did not affect RDI, the intervention was associated with a higher pCR in patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative and triple-negative breast cancer undergoing neoadjuvant chemotherapy.

Effect of Metformin Versus Placebo on New Primary Cancers in Canadian Cancer Trials Group MA.32: A Secondary Analysis of a Phase III Randomized Double-Blind Trial in Early Breast Cancer.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned coprimary or secondary analyses are not yet available. Clinical trial updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.Metformin has been associated with lower cancer risk in epidemiologic and preclinical research. In the MA.32 randomized adjuvant breast cancer trial, metformin (v placebo) did not affect invasive disease-free or overall survival. Here, we report metformin effects on the risk of new cancer. Between 2010 and 2013, 3,649 patients with breast cancer younger than 75 years without diabetes with high-risk T1-3, N0-3 M0 breast cancer (any estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2) were randomly assigned to metformin 850 mg orally twice a day or placebo twice a day for 5 years. New primary invasive cancers (outside the ipsilateral breast) developing as a first event were identified. Time to events was described by the competing risks method; two-sided likelihood ratio tests adjusting for age, BMI, smoking, and alcohol intake were used to compare metformin versus placebo arms. A total of 184 patients developed new invasive cancers: 102 metformin and 82 placebo, hazard ratio (HR), 1.25; 95% CI, 0.94 to 1.68; P = .13. These included 48 contralateral invasive breast cancers (27 metformin v 21 placebo), HR, 1.29; 95% CI, 0.72 to 2.27; P = .40 and 136 new nonbreast primary cancers (75 metformin v 61 placebo), HR, 1.24; 95% CI, 0.88 to 1.74; P = .21. Metformin did not reduce the risk of new cancer development in these nondiabetic patients with breast cancer.

Effect of Exercise on Chemotherapy-Induced Peripheral Neuropathy Among Patients Treated for Ovarian Cancer: A Secondary Analysis of a Randomized Clinical Trial.

Importance: Chemotherapy-induced peripheral neuropathy (CIPN), one of the most common and severe adverse effects of chemotherapy, is associated with worse quality of life among survivors of ovarian cancer. Currently, there is no effective treatment for CIPN. Objective: To evaluate the effect of a 6-month aerobic exercise intervention vs attention-control on CIPN among women treated for ovarian cancer in the Women's Activity and Lifestyle Study in Connecticut (WALC) to provide evidence to inform the guidelines and recommendations for prevention or treatment of CIPN. Design, Setting, and Participants: This prespecified secondary analysis evaluated the Women's Activity and Lifestyle Study in Connecticut (WALC), a multicentered, open-label, population-based, phase 3 randomized clinical trial of an aerobic exercise intervention vs attention control for CIPN in patients who were diagnosed with ovarian cancer. Only WALC participants who received chemotherapy were included in this analysis. Participants were randomized 1:1 to either a 6-month aerobic exercise intervention or to attention control. All analyses were conducted between September 2022 and January 2023. Interventions: The exercise intervention consisted of home-based moderate-intensity aerobic exercise facilitated by weekly telephone counseling from an American College of Sports Medicine/American Cancer Society-certified cancer exercise trainer. Attention control involved weekly health education telephone calls from a WALC staff member. Main Outcomes and Measure: Change in CIPN was the primary outcome in this secondary analysis. This outcome was represented by CIPN severity, which was self-measured by participants at baseline and 6 months using the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity scale, with a score range of 0 to 44. A mixed-effects model was used to assess the 6-month change in CIPN between the exercise intervention and attention control arms. Results: Of the 134 participants (all females; mean [SD] age, 57.5 [8.3] years) included in the analysis, 69 were in the exercise intervention arm and 65 were in the attention control arm. The mean (SD) time since diagnosis was 1.7 (1.0) years. The mean (SD) baseline CIPN scores were 8.1 (5.6) in the exercise intervention arm and 8.8 (7.9) in the attention control arm (P = .56). At 6 months, the self-reported CIPN score was reduced by 1.3 (95% CI, -2.3 to -0.2) points in the exercise intervention arm compared with an increase of 0.4 (95% CI, -0.8 to 1.5) points in the attention control arm. The between-group difference was -1.6 (95% CI, -3.1 to -0.2) points. The point estimate was larger among the 127 patients with CIPN symptoms at enrollment (-2.0; 95% CI, -3.6 to -0.5 points). Conclusions and Relevance: Findings of this secondary analysis of the WALC trial indicate that a 6-month aerobic exercise intervention vs attention control significantly improved self-reported CIPN among patients who were treated for ovarian cancer. While replication of the findings in other studies is warranted, incorporating referrals to exercise programs into standard oncology care could reduce CIPN symptoms and increase quality of life in patients with ovarian cancer.

Randomized trial of exercise on cancer-related blood biomarkers and survival in women with ovarian cancer.

BACKGROUND: In randomized trials in women with breast cancer, exercise has been shown to have beneficial effects on cancer-related circulating biomarkers that may impact survival. Such studies are lacking for ovarian cancer. METHODS: This secondary analysis of a published randomized controlled trial examined the impact of a 6-month exercise intervention versus attention-control on change in prespecified circulating biomarkers (cancer antigen 125 (CA-125), C-reactive protein (CRP), insulin-like growth factor-1(IGF-1), insulin and leptin) in a subset of participants who provided a fasting blood draw (N = 104/144) at enrollment and at 6 months. Change in biomarkers between study arms was compared using a linear mixed effects model analysis. An exploratory analysis of the exercise intervention versus attention-control on all-cause mortality included all (N = 144) participants. All statistical tests were two-sided. RESULTS: Participants included in the biomarker analysis were 57.0 ± 8.8 (mean ± SD) years old and 1.6 ± 0.9 years post-diagnosis. Adherence to the exercise intervention was 176.4 ± 63.5 min/week. Post intervention IGF-1 (group difference in change: -14.2 (-26.1 to -2.3) ng/mL (least squared means (95% CI))) and leptin (-8.9 (-16.5 to -1.4) ng/mL) were significantly reduced in the exercise group (N = 53) compared to those in attention-control (N = 51). No group difference in change was seen for CA-125 (p = 0.54), CRP (p = 0.95), or insulin (p = 0.37). With median follow-up of 70 months [range 6.6-105.4 months], 50/144 (34.7%) (exercise group; 24/74 (32.4%) versus attention-control group; 26/70 (37.1%)) participants died with no between group difference in overall survival (p = 0.99). CONCLUSIONS: Further studies are needed to determine the clinical significance of exercise-induced changes in cancer-related circulating biomarkers in women with ovarian cancer.

Metformin, placebo, and endocrine therapy discontinuation among participants in a randomized double-blind trial of metformin vs placebo in hormone receptor-positive early-stage breast cancer (CCTG MA32).

BACKGROUND: The MA32 study investigated whether 5 years of metformin (versus placebo) improves invasive disease-free survival in early-stage breast cancer (BC). Non-adherence to endocrine therapy (ET) and medications for chronic conditions is common and increases with drug toxicity and polypharmacy. This secondary analysis evaluates rates and predictors of early discontinuation of metformin, placebo, and ET among participants with HR-positive BC. METHODS: Patients with high-risk non-metastatic BC were randomized to 60 months of metformin (850 mg BID) or placebo BID. Patients were administered bottles of metformin/placebo every 180 days. Metformin/placebo adherence was defined as a bottle dispensed at month 48 or later. The ET adherence analysis included patients with HR-positive BC who received ET with start and stop date reported, with adherence defined as > 48 months of use. Associations of covariates with study drug and ET adherence were examined using multivariable models. RESULTS: Among the 2521 HR-positive BC patients, 32.9% were non-adherent to study drug. Non-adherence was higher among patients on metformin vs placebo (37.1% vs 28.7%, p < 0.001). Reassuringly, ET discontinuation rates were similar between treatment arms (28.4% vs 28.0%, p = 0.86). Patients who were non-adherent to ET were more likely to discontinue study therapy (38.8% vs 30.1%, p < 0.0001). In a multivariable analysis, study drug non-adherence was increased with metformin vs placebo (OR: 1.50, 95% CI 1.25-1.80; p < 0.0001); non-adherence to ET (OR: 1.47, 95% CI 1.20-1.79, p < 0.0001); grade 1 or greater GI toxicity during the first 2 years; lower age; and higher body mass index. CONCLUSION: While non-adherence was higher among patients on metformin, it was still considerable among patients on placebo. Reassuringly, treatment arm allocation did not impact ET adherence. Attention to global medication adherence is needed to improve BC and non-oncological outcomes in cancer survivors. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01.

Effects of an educational physical activity intervention in young women with newly diagnosed breast cancer: Findings from the Young and Strong Study.

BACKGROUND: Obesity and inactivity are poor prognostic factors in breast cancer, but less is known regarding physical activity (PA) and weight patterns in young breast cancer survivors. METHODS: The Young and Strong Study was a cluster-randomized trial evaluating education and support interventions for young women (age <45 years) with newly diagnosed breast cancer. Sites were randomized 1:1 to a Young Women's Intervention (YWI) or a contact-time control physical activity intervention (PAI). Changes in PA and weight were compared between groups using general estimating equations to evaluate clustered binary and Gaussian data. RESULTS: A total of 467 patients enrolled between July 2012 and December 2013 across 54 sites. Median age at diagnosis was 40 years (range, 22-45). At baseline, median body mass index (BMI) was 25.4 kg/m2 (range, 16.1-61.1), and participants reported a median of 0 minutes (range, 0-2190) of moderate/vigorous PA/week. PA increased significantly over time in both groups (p < .001), with no difference between groups at any time point. BMI increased modestly but significantly (p < .001) over time in both groups. Provider attention to PA was observed in 74% of participants on PAI and 61% on YWI (p = .145) and correlated with PA at 12 months (median 100 min/week of PA in participants with provider attention to PA vs. 60 min/week in those without, p = .016). CONCLUSIONS: In a cohort of young women with breast cancer, rates of obesity and inactivity were high. PA and BMI increased over time and were not impacted by an educational PA intervention. Findings provide important information for developing lifestyle interventions for young breast cancer survivors.

Virtual acupressure for symptom management in cancer populations during COVID-19: a retrospective analysis.

OBJECTIVE: Following the outbreak of COVID-19, access to in-person oncology acupuncture service was temporarily disrupted at Dana-Farber Cancer Institute, a National Cancer Institute (NCI)-designated cancer center. During this period, a virtual acupuncturist-guided session of patient self-acupressure was implemented to provide continuity of supportive care for cancer patients. We provide preliminary findings on the feasibility and potential impact of remotely delivered acupressure on patient-reported symptom burden in cancer populations. METHODS: This is a retrospective chart review of cancer patients who received virtual acupressure service at a single academic cancer center from May 11 to December 31, 2020. Each telehealth session consisted of a one-on-one appointment between the patient and acupuncturist. A semi-standardized set of acupoints were used, including Yintang, ST36, GB20, PC6, and HT7 as well as Relaxation Point on the ear. At the start of each session, Edmonton Symptom Assessment System (ESAS) was used to collect patient-reported symptom burden. For patients with at least one follow-up within 14 days of the baseline visit, paired t-test was used to analyze changes in ESAS scores from baseline to first follow-up. RESULTS: A total of 102 virtual acupressure sessions were administered to 32 patients. Most patients were females (90.6%) and white (84.4%), and the mean age was 55.7 (range = 26-82; SD = 15.7). The most common cancer diagnosis was breast (53.1%), followed by pancreatic (12.5%) and lung (9.4%). Baseline ESAS Total, Physical, and Emotional scores were 21.5 (SD = 11.1), 12.4 (SD = 7.5), and 5.2 (SD = 3.8), respectively. Of 32 patients, 13 (41%) had a second acupressure session within 14 days. For these 13 patients, there was a statistically significant reduction in Total symptom burden (-4.9 ± 7.6; p = 0.04) and in Physical (-3.5 ± 5.4; p = 0.04) and Emotional (-1.2 ± 1.8; p = 0.03) subscales from baseline to follow-up. CONCLUSION: Virtual acupressure was associated with significant reduction in symptom burden among cancer patients from their baseline to follow-up visits. Larger scale randomized clinical studies are needed to confirm these findings and better understand the impact of virtual acupressure on symptom burden in cancer populations.

Wearable sensor-based performance status assessment in cancer: A pilot multicenter study from the Alliance for Clinical Trials in Oncology (A19_Pilot2).

Clinical performance status is designed to be a measure of overall health, reflecting a patient's physiological reserve and ability to tolerate various forms of therapy. Currently, it is measured by a combination of subjective clinician assessment and patient-reported exercise tolerance in the context of daily living activities. In this study, we assess the feasibility of combining objective data sources and patient-generated health data (PGHD) to improve the accuracy of performance status assessment during routine cancer care. Patients undergoing routine chemotherapy for solid tumors, routine chemotherapy for hematologic malignancies, or hematopoietic stem cell transplant (HCT) at one of four sites in a cancer clinical trials cooperative group were consented to a six-week prospective observational clinical trial (NCT02786628). Baseline data acquisition included cardiopulmonary exercise testing (CPET) and a six-minute walk test (6MWT). Weekly PGHD included patient-reported physical function and symptom burden. Continuous data capture included use of a Fitbit Charge HR (sensor). Baseline CPET and 6MWT could only be obtained in 68% of study patients, suggesting low feasibility during routine cancer treatment. In contrast, 84% of patients had usable fitness tracker data, 93% completed baseline patient-reported surveys, and overall, 73% of patients had overlapping sensor and survey data that could be used for modeling. A linear model with repeated measures was constructed to predict the patient-reported physical function. Sensor-derived daily activity, sensor-derived median heart rate, and patient-reported symptom burden emerged as strong predictors of physical function (marginal R2 0.429-0.433, conditional R2 0.816-0.822).

Obesity and metabolic dysfunction correlate with background parenchymal enhancement in premenopausal women.

OBJECTIVE: This study tested the hypothesis that obesity and metabolic abnormalities correlate with background parenchymal enhancement (BPE), the volume and intensity of enhancing fibroglandular breast tissue on dynamic contrast-enhanced magnetic resonance imaging. METHODS: Participants included 59 premenopausal women at high risk of breast cancer. Obesity was defined as BMI ≥ 30 kg/m2 . Metabolic parameters included dual-energy x-ray absorptiometry-quantified body composition, plasma biomarkers of insulin resistance, adipokines, inflammation, lipids, and urinary sex hormones. BPE was assessed using computerized algorithms on dynamic contrast-enhanced magnetic resonance imaging. RESULTS: BMI was positively correlated with BPE (r = 0.69; p < 0.001); participants with obesity had higher BPE than those without obesity (404.9 ± 189.6 vs. 261.8 ± 143.8 cm2 ; Δ: 143.1 cm2 [95% CI: 49.5-236.7]; p = 0.003). Total body fat mass (r = 0.68; p < 0.001), body fat percentage (r = 0.64; p < 0.001), visceral adipose tissue area (r = 0.65; p < 0.001), subcutaneous adipose tissue area (r = 0.60; p < 0.001), insulin (r = 0.59; p < 0.001), glucose (r = 0.35; p = 0.011), homeostatic model of insulin resistance (r = 0.62; p < 0.001), and leptin (r = 0.60; p < 0.001) were positively correlated with BPE. Adiponectin (r = -0.44; p < 0.001) was negatively correlated with BPE. Plasma biomarkers of inflammation and lipids and urinary sex hormones were not correlated with BPE. CONCLUSIONS: In premenopausal women at high risk of breast cancer, increased BPE is associated with obesity, insulin resistance, leptin, and adiponectin.

Exploring Clinicians' Perspectives of Barriers to Chemotherapy-Induced Peripheral Neuropathy Assessment and Management in Oncology Practice: A Qualitative Analysis of Semi-structured Interviews.

BACKGROUND: Quantitative reports suggest that the assessment and management of chemotherapy-induced peripheral neuropathy (CIPN) in practice is suboptimal. OBJECTIVE: The purpose of this qualitative analysis was to explore clinician-related perspectives of CIPN assessment, management, and the use of a CIPN decision support tool. METHODS: Clinicians from the breast oncology, gastrointestinal oncology, or multiple myeloma disease centers at Dana-Farber Cancer Institute who interacted with a CIPN clinician decision support algorithm were eligible to participate in the semi-structured interviews. The interview guide included questions about CIPN assessment, management, and clinician-decision support tool use. All interviews were audio-recorded, transcribed, and analyzed using inductive content analysis. RESULTS: Of the 39 eligible clinicians, 15 agreed to be interviewed. Interviewed clinicians were mainly physicians (73.3) and White, non-Hispanic (93.3%). Main themes from the interviews included (1) CIPN management practice patterns (eg, endorsement of non-recommended management strategies or lack of standardization for chemotherapy dose reduction) and barriers (eg, insurance prior authorizations required for duloxetine prescription), (2) CIPN assessment practice patterns (eg, use of subjective instead of objective CIPN assessment approaches) and barriers (eg, difficult to interpret patients' CIPN report between visits), and (3) utilization of the clinician decision support tool (eg, all assessment tasks lead to same management options). CONCLUSIONS: There are several barriers to clinicians' use of evidence-based CIPN assessment and management strategies. IMPLICATIONS FOR PRACTICE: Future work should be focused on addressing barriers to duloxetine prescription, developing evidence-based CIPN assessment and management strategies, improving symptom monitoring, and facilitating referrals to existing supportive care services.

Effect of exercise on body composition among women with ovarian cancer.

PURPOSE: Obesity is associated with a higher risk of mortality in women with ovarian cancer. Exercise has improved body composition among cancer survivors, yet no randomized controlled trial has explored the effect of exercise on body composition in women with ovarian cancer. In this analysis, we examined the effect of a six-month aerobic exercise intervention on body composition among ovarian cancer survivors in the Women's Activity and Lifestyle Study in Connecticut (WALC). METHODS: Women with ovarian cancer (N = 144) were randomized in a 1:1 ratio to 6 months of an aerobic exercise intervention or attention-control, and body composition was measured as a secondary outcome at baseline and 6 months via dual-energy X-ray absorptiometry (DEXA). Women with at least one DEXA scan were included in the analysis (N = 103). RESULTS: On average, participants were 57.1 (± 8.7) years old and 1.6 (± 0.9) years since diagnosis. Women randomized to exercise maintained weight during the trial (- 0.11 kg, P = 0.82), while women in attention-control gained weight (+ 1.40 kg, P = 0.03); however, the between-group difference did not reach statistical significance (P = 0.09). We found no statistically significant differences by study arm for changes in body fat percentage, bone mineral density, or lean body mass. CONCLUSIONS: Weight was maintained as a result of a 6-month aerobic exercise intervention among post-treatment ovarian cancer survivors. Future exercise and healthy eating interventions should consider additional measures (e.g., computer tomography scans, D3-creatinine) to more accurately assess changes in body composition. IMPLICATIONS FOR CANCER SURVIVORS: Moderate-intensity aerobic exercise may help ovarian cancer survivors maintain weight.
