Financial Hardship & Neighborhood Socioeconomic Disadvantage in Long-term Childhood Cancer Survivors.

BACKGROUND: Long-term survivors of childhood cancer face elevated risk for financial hardship. We evaluate whether childhood cancer survivors live in areas of greater deprivation and the association with self-reported financial hardships. METHODS: Cross-sectional analysis of data from the Childhood Cancer Survivor Study (CCSS) between 1970 and 1999, and self-reported financial information from 2017-2019. We measured neighborhood deprivation with the Area Deprivation Index (ADI) based on current zip code. Financial hardship was measured with validated surveys that captured behavioral, material/financial sacrifice, and psychological hardship. Bivariate analyses described neighborhood differences between survivors and siblings. Generalized linear models estimated effect sizes between ADI and financial hardship adjusting for clinical factors and personal socioeconomic status. RESULTS: Analysis was restricted to 3,475 long-term childhood cancer survivors and 923 sibling controls. Median ages at time of evaluation was 39 [IQR 33,46] and 47 [39,59] years, respectively. Survivors resided in areas with greater deprivation (ADI ≥ 50: 38.7% survivors vs 31.8% siblings, P < .001). One quintile increases in deprivation were associated with small increases in behavioral (2nd quintile P = .017) and psychological financial hardship (2nd quintile P = .009; 3rd quintile, P = .014). Lower psychological financial hardship was associated with individual factors including greater household income ($60,000+ income, P < .001) and being single (P = .048). CONCLUSIONS AND RELEVANCE: Childhood cancer survivors were more likely to live in areas with socioeconomic deprivation. Both neighborhood level disadvantage and personal socioeconomic circumstances should be evaluated when trying to assist childhood cancer survivors with financial hardships.

Patient-Reported Outcomes in OlympiA: A Phase III, Randomized, Placebo-Controlled Trial of Adjuvant Olaparib in gBRCA1/2 Mutations and High-Risk Human Epidermal Growth Factor Receptor 2-Negative Early Breast Cancer.

PURPOSE: The OlympiA randomized phase III trial compared 1 year of olaparib (OL) or placebo (PL) as adjuvant therapy in patients with germline BRCA1/2, high-risk human epidermal growth factor receptor 2-negative early breast cancer after completing (neo)adjuvant chemotherapy ([N]ACT), surgery, and radiotherapy. The patient-reported outcome primary hypothesis was that OL-treated patients may experience greater fatigue during treatment. METHODS: Data were collected before random assignment, and at 6, 12, 18, and 24 months. The primary end point was fatigue, measured with the Functional Assessment of Chronic Illness Therapy-Fatigue scale. Secondary end points, assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, Core 30 item, included nausea and vomiting (NV), diarrhea, and multiple functional domains. Scores were compared between treatment groups using mixed model for repeated measures. Two-sided P values <.05 were statistically significant for the primary end point. All secondary end points were descriptive. RESULTS: One thousand five hundred and thirty-eight patients (NACT: 746, ACT: 792) contributed to the analysis. Fatigue severity was statistically significantly greater for OL versus PL, but not clinically meaningfully different by prespecified criteria (≥3 points) at 6 months (diff OL v PL: NACT: -1.3 [95% CI, -2.4 to -0.2]; P = .022; ACT: -1.3 [95% CI, -2.3 to -0.2]; P = .017) and 12 months (NACT: -1.6 [95% CI, -2.8 to -0.3]; P = .017; ACT: -1.3 [95% CI, -2.4 to -0.2]; P = .025). There were no significant differences in fatigue severity between treatment groups at 18 and 24 months. NV severity was worse in patients treated with OL compared with PL at 6 months (NACT: 6.0 [95% CI, 4.1 to 8.0]; ACT: 5.3 [95% CI, 3.4 to 7.2]) and 12 months (NACT: 6.4 [95% CI, 4.4 to 8.3]; ACT: 4.5 [95% CI, 2.8 to 6.1]). During treatment, there were some clinically meaningful differences between groups for other symptoms but not for function subscales or global health status. CONCLUSION: Treatment-emergent symptoms from OL were limited, generally resolving after treatment ended. OL- and PL-treated patients had similar functional scores, slowly improving during the 24 months after (N)ACT and there was no clinically meaningful persistence of fatigue severity in OL-treated patients.

Type I interferons, inflammation, and fatigue in a longitudinal RNA study of women with breast cancer.

BACKGROUND: Fatigue is a common side effect of cancer and its treatment and is thought to be driven in part by activation of the proinflammatory cytokine network. However, the cellular and molecular underpinnings of cancer-related fatigue (CRF) have not been determined, nor have immune pathways beyond inflammation been carefully investigated. The goal of this study was to examine the association between CRF and activation of canonical proinflammatory gene regulation pathways and Type I interferon (IFN) signaling pathways in breast cancer patients during and after treatment. METHODS: Women diagnosed with early-stage breast cancer (n = 181) completed assessments before and after treatment with radiation and/or chemotherapy and at 6, 12, and 18-month post-treatment follow-ups. Assessments included self-reported fatigue (Multidimensional Fatigue Symptom Inventory - Short Form) and expression of pre-specified sets of Type I IFN and pro-inflammatory immune response genes determined from mRNA sequencing of PBMCs. Mixed effect linear models examined changes in fatigue and immune gene expression over time and tested the hypothesis that fatigue would be associated with increased expression of Type I IFN and inflammatory response genes. RESULTS: There were significant changes in fatigue and immune gene expression across the assessment period; all measures increased from pre- to post-treatment but showed diverging patterns over the follow-up, with declines in fatigue and persistent elevations in Type I IFN and proinflammatory gene expression. In mixed effect linear models, expression of Type I IFN response genes was elevated in association with fatigue across the assessment period, from pre-treatment to 18-month follow-up. In contrast, pro-inflammatory gene expression was associated with fatigue only at 6, 12, and 18-month follow-ups. Analyses controlling for changes in leukocyte subsets continued to show a significant association between fatigue and Type I IFN gene expression but reduced the time-dependent association with pro-inflammatory gene expression to non-significant. CONCLUSIONS: Results revealed unexpected complexity in the immune underpinnings of CRF and identify a novel role for IFN signaling as a robust contributor to this symptom before, during, and after treatment. Pro-inflammatory gene expression emerged as a predictor of fatigue later in the cancer trajectory, and that effect was primarily accounted for by a concurrent increase in monocyte prevalence.

History and current status of the survivorship care program at the University of California, Los Angeles Jonsson Comprehensive Cancer Center (UCLA JCCC).

As one of the first comprehensive cancer centers to receive a designation from the National Cancer Institute, the Jonsson Comprehensive Cancer Center at UCLA Health has served as a leader in survivorship research for three decades. A clinical survivorship program for childhood cancer survivors was established in the early 2000s as this became a standard of care in pediatric oncology. However, it was not until receipt of external funding and the establishment of a Survivorship Center of Excellence in 2006 that clinical services were expanded to include adult cancer survivors, as well as survivorship care delivery research in the community and at affiliated clinical sites. When this funding ended, there was limited institutional support for expansion of the program, and so the clinical programs did not develop further. Recently, there has been renewed interest in obtaining Commission on Cancer accreditation, and this has prompted an institutional assessment of survivorship care to inform future activities for system-wide program development. As oncology care expands throughout a large regional health system network, the future survivorship program will need to serve as a common resource for the entire health system by providing a repository of specialized services and resources as well as standard processes and pathways for a cohesive approach to care. IMPLICATIONS FOR CANCER SURVIVORS: There are many challenges to development and sustainment of cancer survivorship programs, even in NCI-designated comprehensive cancers. As the delivery of cancer care services expands and becomes more integrated in large health care systems, innovative strategies are needed to ensure delivery of tailored care to cancer survivors through acute treatment and beyond.

Work Productivity Among Younger Breast Cancer Survivors: The Impact of Behavioral Interventions for Depression.

OBJECTIVES: The Pathways to Wellness randomized controlled trial found that 2 behavioral interventions, mindfulness awareness practices and survivorship education, reduced depressive symptoms in younger breast cancer survivors (BCSs) compared with wait-list control. This secondary analysis examines whether the interventions led to reduced loss of work productivity among younger BCSs and whether such reductions were mediated by reductions in depressive symptoms. METHODS: The Work Productivity and Activity Impairment scale was used to measure work productivity loss at 4 assessment time points. Correlates of productivity loss at enrollment were examined using multivariable linear regression. Differences in change over time in productivity loss between each intervention group and control were assessed using linear mixed models. Reduced depressive symptoms were tested as a mediator of reduced productivity loss. RESULTS: Of 247 trial participants, 199 were employed and included in the analyses. At enrollment, higher productivity loss was associated with chemotherapy receipt (P = .003), younger age (P = .021), more severe cognitive problems (P = .002), higher musculoskeletal pain severity (P = .002), more depressive symptoms (P = .016), and higher fatigue severity (P = .033). The mindfulness intervention led to significantly less productivity loss compared with control at all 3 postintervention assessment points (all P < .05), with about 54% of the effect mediated by reduction in depressive symptoms. Survivorship education was not associated with reduced loss of productivity. CONCLUSIONS: These findings suggest that addressing depressive symptoms through behavioral interventions, such as mindfulness, may mitigate impacts on work productivity in younger BCSs.

Survivorship care in breast cancer: understanding implementation barriers through the lens of the Theoretical Domains Framework.

BACKGROUND: Breast cancer survivorship guidelines with specific recommendations on managing long-term effects are available, but uptake in clinical practice remains low. Using the lens of the Theoretical Domains Framework, we aimed to understand key factors in guideline-concordant management of long-term effects to inform future implementation efforts in clinical practice contexts. METHODS: As part of a broader survey of oncologists, a theory-guided questionnaire was developed. Oncologists were asked to report level of agreement with Theoretical Domains Framework-based statements, current usage and perceived value of survivorship resources, and frequency of managing long-term effects in routine care. Data analyses included psychometric assessment of the questionnaire, descriptive summaries of theoretical domains and survivorship resources, and multivariable logistic regression models. RESULTS: In total, 217 oncologists completed the Theoretical Domains Framework-based questionnaire; 54% of oncologists reported "always or almost always" evaluating physical effects at routine survivorship appointments, while 34% did so for psychosocial effects. In regression models, Environmental Context and Resources was the only theoretical domain found to be statistically significantly associated with "always or almost always" evaluating both physical (odds ratio = 0.29, 95% confidence interval = 0.09 to 0.80) and psychosocial (odds ratio = 0.09, 95% confidence interval = 0.02 to 0.35) effects. CONCLUSIONS: Findings support application of the Theoretical Domains Framework in understanding oncologists' behaviors and perceived barriers in managing long-term effects in breast cancer survivors. In future implementation efforts, this theory-informed approach can be used to target relevant domains and strategies focused on embedding guideline recommendations in the clinical context through structured resources and environmental supports.

Mental health and care utilization in survivors of adolescent and young adult cancer.

BACKGROUND: Adolescent and young adult cancer survivors experience mental health challenges, yet little is known about the evolution of these difficulties. This study explored mental health symptoms and utilization among long-term adolescent and young adult cancer survivors. METHODS: Using 30 432 respondents from the 2019 National Health Interview Survey, this study compared adults with a history of adolescent and young adult cancer (diagnosed when patients were between 15 and 39 years of age) to adults without adolescent and young adult cancer. Mental health symptom severity was measured using the Patient Health Questionnaire depression scale and 7-item Generalized Anxiety Disorder questionnaires. Care utilization constituted psychotherapy and mental health medication use. Inverse propensity score weights were used to balance demographics and combined with survey weights. Descriptive statistics, multivariable generalized linear models, and structural equation modeling with 2-sided tests were used for analysis. RESULTS: We compared 639 adolescent and young adult survivors with 29 793 controls. Survivors were, on average, 20.5 years (SE = 0.74) past their cancer diagnosis dates. After adjusting for survey and propensity score weights, adolescent and young adult survivors reported more severe depression (incidence rate ratio = 1.42, 95% confidence interval [CI] = 1.09 to 1.84, P < .01) and anxiety (incidence rate ratio = 1.85, 95% CI = 1.55 to 2.21, P < .001). They were more likely to use psychotherapy (odds ratio = 1.91, 95% CI = 1.16 to 3.17, P < .05) and mental health medications (odds ratio = 1.89, 95% CI = 1.15 to 3.11, P < .05). Time since diagnosis was negatively associated with symptoms and utilization. Structural equation modeling demonstrated mediation of utilization effect by symptom severity. CONCLUSIONS: Adolescent and young adult survivors experience worse mental health in late survivorship, despite small improvements over time. We highlight the importance of survivorship care that addresses the long-term mental health needs of these survivors.

Effects of a Cognitive Behavioral Digital Therapeutic on Anxiety and Depression Symptoms in Patients With Cancer: A Randomized Controlled Trial.

PURPOSE: Patients with cancer often experience elevated levels of distress. This double-blind, randomized controlled trial compared the impact of an app-based version of cognitive behavioral stress management (CBSM) versus a health education sham app on anxiety and depression symptoms. METHODS: Patients with nonmetastatic (stage I-III) cancer who were receiving or recently completed (≤6 months) systemic treatment were recruited nationwide. The primary outcome of change in anxiety symptoms (PROMIS-Anxiety) over 12 weeks and the top secondary outcome of change in depression symptoms (PROMIS-Depression) over 12 weeks were analyzed using mixed-effects modeling with repeated measures (weeks 0, 4, 8, 12). Patient global impressions of change in anxiety and depression were reported at weeks 4, 8, and 12. In addition, self-reported adverse events were collected throughout the study and adjudicated by the site principal investigator. RESULTS: Four hundred forty-nine patients were enrolled in the trial (age M [standard deviation] = 52.44 [11.46]; 81% female; 76% White; 53% breast cancer). Patients randomly assigned to digitized CBSM showed significantly greater reductions in anxiety (B = -0.03; P = .019) and depression (B = -0.02; P = .042) symptoms over 12 weeks. Patients who received digitized CBSM were also significantly more likely to perceive much or very much improvement (v no/minimal change or much/very much worse) in their symptoms of anxiety (χ2 = 31.76; P < .001) and depression (χ2 = 19.70; P < .001) compared with the control. CONCLUSION: The use of digitized CBSM led to significant improvements in anxiety and depression outcomes compared with the sham app.

Dynamic Risk Prediction of Treatment Discontinuation Using Patient-Reported Outcomes Data in the Phase III NSABP B-35 Trial.

Predicting an individual's risk of treatment discontinuation is critical for the implementation of precision chemoprevention. We developed partly conditional survival models to predict discontinuation of tamoxifen or anastrozole using patient-reported outcome (PRO) data from postmenopausal women with ductal carcinoma in situ enrolled in the NSABP B-35 clinical trial. In a secondary analysis of the NSABP B-35 clinical trial PRO data, we proposed two models for treatment discontinuation within each treatment arm (anastrozole or tamoxifen treated patients) using partly conditional Cox-type models with time-dependent covariates. A 70/30 split of the sample was used for the training and validation datasets. The predictive performance of the models was evaluated using calibration and discrimination measures based on the Brier score and AUC from time-dependent ROC curves. The predictive models stratified high-risk versus low-risk early discontinuation at a 6-month horizon. For anastrozole-treated patients, predictive factors included baseline body mass index (BMI) and longitudinal patient-reported symptoms such as insomnia, joint pain, hot flashes, headaches, gynecologic symptoms, and vaginal discharge, all collected up to 12 months [Brier score, 0.039; AUC, 0.76; 95% confidence interval (CI), 0.57-0.95]. As for tamoxifen-treated patients, predictive factors included baseline BMI, and time-dependent covariates: cognitive problems, feelings of happiness, calmness, weight problems, and pain (Brier score, 0.032; AUC, 0.78; 95% CI, 0.65-0.91). A real-time calculator based on these models was developed in Shiny to create a web-based application with a future goal to aid healthcare professionals in decision-making. PREVENTION RELEVANCE: The dynamic prediction provided by partly conditional models offers valuable insights into the treatment discontinuation risks using PRO data collected over time from clinical trial participants. This tool may benefit healthcare professionals in identifying patients at high risk of premature treatment discontinuation and support interventions to prevent potential discontinuation.

Validating the PROMIS cognitive function short form in cancer survivors.

PURPOSE: The Patient-Reported Outcome Measurement Information System Cognitive Function Short Form 8a  (PROMIS Cog) could provide a shorter, useful alternative to the often used Functional Assessment of Cancer Therapy - Cognition (FACT-Cog) in research and clinical care. This study aimed to determine the convergent validity and internal reliability of the PROMIS Cog in 3 separate samples of breast cancer survivors and to explore clinical cut points. METHODS: Data from three samples of breast cancer survivors were used for this secondary analysis. Convergent validity was determined by evaluating correlation strength among the derived PROMIS Cog and measures of depression, anxiety, stress, fatigue, sleep, loneliness, the FACT-Cog . Clinical cut-points for the PROMIS Cog were determined by plotting the receiver operating characteristic curves. RESULTS: 3 samples of breast cancer survivors (N = 471, N = 132, N = 90) were included. Absolute values of correlations demonstrating convergent validity ranged from 0.21 to 0.82, p's < 0.001, and were comparable to correlations with the full FACT-Cog 18 item perceived cognitive impairments (PCI) scale. ROC curve plots indicated a clinical cut off < 34 for the combined sample. CONCLUSION: The 8-item PROMIS Cog demonstrated good convergent validity and internal reliability in breast cancer survivors, comparable to the 18-item FACT-Cog PCI. The PROMIS Cog 8a is a brief self-report measure that can be easily incorporated into cancer-related cognitive impairment research designs or used in clinical settings.

Socioeconomic Factors and Adherence to Health Care Recommendations in Adolescent and Young Adult Cancer Survivors.

Purpose: The majority of adolescent and young adult (AYA) cancer survivors do not receive recommended health care surveillance after therapy. We used cross-sectional survey data to evaluate the impact of income, education, marital status, and insurance on health care adherence among AYA survivors. Methods: Eligible survivors were 18-39 years at diagnosis with invasive malignancy, 1-5 years from therapy completion. Online surveys assessed sociodemographic factors and self-report of completion of recommended health care services. Diagnosis and treatment data were abstracted from medical records. Multivariable logistic regression calculated odds ratios (ORs) and 95% confidence intervals (CIs) for adherence in relation to socioeconomic status and support. Results: Of 344 participants, 36% were adherent to at least 80% of recommendations. Adherence varied by cancer type: 34% for breast cancer, 52% for leukemia/lymphoma, 23% for other tumors. Adherence rates were similar among White, Asian, and Hispanic/Latinx patients. Lower adherence was associated with lower education (OR: 0.43; 95% CI: 0.23-0.80 for <4-year college degree) and lower annual income (OR: 0.51; 95% CI: 0.28-0.95 for $41,000-$80,000; OR: 0.40; 95% CI: 0.19-0.86 for ≤$40,000). Adherence decreased with decreasing income levels among those who were 1 to less than 3 years after diagnosis (OR: 0.25; 95% CI: 0.07-0.93 for $81,000-$120,000; OR: 0.24; 95% CI: 0.07-0.84 for $41,000-$80,000; OR: 0.13; 95% CI: 0.03-0.60 for ≤$40,000). Conclusion: Risk of nonadherence to health care guidelines was associated with lower income and lower education among AYA cancer survivors. Identification of these risks and related barriers to adherence in AYA survivors will inform interventions designed to meet needs of these high-risk groups, particularly during the first years after diagnosis. Trial Registration: NCT02192333.

Simulation study comparing analytical methods for single-item longitudinal patient-reported outcomes data.

PURPOSE: Efficient analytical methods are necessary to make reproducible inferences on single-item longitudinal ordinal patient-reported outcome (PRO) data. A thorough simulation study was performed to compare the performance of the semiparametric probabilistic index models (PIM) with a longitudinal analysis using parametric cumulative logit mixed models (CLMM). METHODS: In the setting of a control and intervention arm, we compared the power of the PIM and CLMM to detect differences in PRO adverse event (AE) between these groups using several existing and novel summary scores of PROs. For each scenario, PRO data were simulated using copula multinomial models. Comparisons were also exemplified using clinical trial data. RESULTS: On average, CLMM provided substantially greater power than the PIM to detect differences in PRO-AEs between the groups when the baseline-adjusted method was used, and a small advantage in power when using the baseline symptom as a covariate. CONCLUSION: Although the CLMM showed the best performance among analytical methods, it relies on assumptions difficult to verify and that might not be fulfilled in the real world, therefore our recommendation is the use of PIM models with baseline symptom as a covariate.

Inclusion of a core patient-reported outcomes battery in adolescent and young adult cancer clinical trials.

Disparities in care, treatment-related toxicity and health-related quality of life (HRQoL) for adolescents and young adults (AYAs, aged 15-39 years) with cancer are under-addressed partly because of limited collection of patient-reported outcomes (PROs) in cancer clinical trials (CCTs). The AYA years include key developmental milestones distinct from younger and older patients, and cancer interrupts attainment of critical life goals. Lack of consensus on a standardized approach to assess HRQoL and treatment-related toxicity in AYA CCTs has limited the ability to improve patient outcomes. The National Cancer Institute's Clinical Trials Network AYA PRO Task Force was assembled to reach consensus on a core set of PROs and foster its integration into AYA CCTs. Eight key considerations for selecting the core PRO AYA battery components were identified: relevance to AYAs; importance of constructs across the age continuum; prioritization of validated measures; availability of measures without licensing fees; availability in multiple languages; applicability to different cancer types and treatments; ability to measure different HRQoL domains and toxicities; and minimized burden on patients and sites. The Task Force used a modified Delphi approach to identify key components of the PRO battery. The Patient-Reported Outcomes Measurement Information System (PROMIS) and the PRO Common Terminology Criteria for Adverse Events Measurement System met all criteria and were selected to assess HRQoL and treatment toxicity, respectively. Investigators are rapidly incorporating the recommendations of the Task Force into AYA trials. Inclusion of a standardized assessment of HRQoL and treatment toxicities in AYA CCTs is a vital first step to develop interventions to improve health outcomes for AYAs diagnosed with cancer.

Current practice patterns and gaps in guideline-concordant breast cancer survivorship care.

PURPOSE: Breast cancer-specific survivorship care guidelines for the more than 3.8 million survivors in the U.S. are available, but implementation in clinical practice remains challenging. We examined current practice patterns and factors associated with guideline-concordant survivorship care among oncologists. METHODS: A national sample of medical oncologists, recruited using two databases, participated in a survey focused on practice patterns for breast cancer survivorship care. A "survivorship care composite score" was calculated for each respondent based on provision of services recommended in the survivorship guidelines. Descriptive statistics and multivariable linear regression analyses examined associations between physician and practice characteristics and composite scores. RESULTS: The survey was completed by 217 medical oncologists, with an overall response rate of 17.9% and eligibility rate of 56.9% for those who responded. Oncologists reported high engagement in evaluation of disease recurrence (78%). Performed less frequently were the provision of survivorship care plans (46%), assessment of psychosocial long-term and late effects (34%), and screening for subsequent cancers (34%). Lack of survivorship care training (p = 0.038) and not routinely informing patients about potential late effects (p = 0.003) were significantly associated with poorer survivorship care composite scores. CONCLUSIONS: Despite the availability of disease-specific survivorship care guidelines, adherence to their recommendations in clinical practice is suboptimal. Survey results identified key gaps in survivorship care for breast cancer survivors, particularly related to subsequent primary cancers and psychosocial long-term and late effects. IMPLICATIONS FOR CANCER SURVIVORS: Improving the delivery of comprehensive survivorship care for the growing population of breast cancer survivors is a high priority. Disease-specific clinical guidelines for cancer survivorship provide valuable recommendations, but innovative strategies are needed to integrate them into the care of long-term breast cancer survivors.

Improving biobehavioral health in younger breast cancer survivors: Pathways to Wellness trial secondary outcomes.

BACKGROUND: The Pathways to Wellness trial tested the efficacy of 2 interventions for younger breast cancer survivors: mindful awareness practices (MAPs) and survivorship education (SE). This planned secondary analysis examines intervention effects on stress, positive psychological outcomes, and inflammation (Clincaltrials.gov NCT03025139). METHODS: Women diagnosed with breast cancer at or before age 50 years who had completed treatment and had elevated depressive symptoms were randomly assigned to 6 weeks of MAPs, SE, or wait-list control (WLC). Assessments conducted at pre- and postintervention and at 3- and 6-month follow-up measured general stress perceptions, cancer-related intrusive thoughts and worry, positive affect, meaning and peace in life, altruism and empathy, and markers of inflammation. Analyses compared change in outcomes over time in each intervention group relative to WLC using linear mixed models. RESULTS: A total 247 women were randomly assigned to MAPs (n = 85), SE (n = 81), or WLC (n = 81). MAPs statistically significantly decreased intrusive thoughts and worry at postintervention and 3-month follow-up relative to WLC (P < .027) and statistically significantly increased positive affect and meaning and peace at postintervention, with positive affect persisting at 3-month follow-up (P < .027). SE statistically significantly decreased intrusive thoughts at 3-month follow-up and statistically significantly increased positive affect at 6-month follow-up relative to WLC (P < .01). Proinflammatory gene expression increased in WLC relative to MAPs (P = .016) but did not differ from SE. There were no intervention effects on other outcomes. CONCLUSION: MAPs had beneficial effects on psychological and immune outcomes in younger breast cancer survivors and is a promising approach for enhancing biobehavioral health.

Toxicity Index, patient-reported outcomes, and persistence of breast cancer chemotherapy-associated side effects in NRG Oncology/NSABP B-30.

Adjuvant chemotherapy improves breast cancer survival but is associated with bothersome short- and long-term toxicity. Factors associated with toxicity, especially subacute toxicity up to 2 years following chemotherapy, have not been fully elucidated. The NRG Oncology/NSABP B-30 clinical trial compared 3 different doxorubicin-, cyclophosphamide-, and docetaxel-based chemotherapy regimens given over 3-6 months. Patients with hormone receptor-positive breast cancer received subsequent adjuvant endocrine therapy. From baseline through 24 months, 2156 patients completed questionnaires serially. We used multivariable probabilistic index models to identify factors associated with acute (>0-12 months) and subacute (>12-24 months) difficulties with pain, cognition, vasomotor symptoms, and vaginal symptoms. For all symptom domains, presence of symptoms prior to chemotherapy initiation were associated with symptoms in the subacute period (all p < 0.001). In addition, different combinations of patient factors and breast cancer treatments were associated with increased likelihood of pain, vasomotor, and vaginal symptoms in the subacute period. Consideration of pre-treatment symptoms and patient factors, as well as treatments for breast cancer, can facilitate identification of groups of patients that may experience symptoms following completion of chemotherapy. This information may be important for treatment-decision-making when alternative regimens are equivalent in benefit.
