RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: The NSABP B-36 compared four cycles of doxorubicin and cyclophosphamide (AC) with six cycles of 5-fluorouracil, epirubicin, and cyclophosphamide (FEC-100) in node-negative early-stage breast cancer. A sub-study within B-36, focusing on symptoms, quality of life (QOL), menstrual history (MH), and cardiac function (CF) was conducted. PATIENTS AND METHODS: Patients completed the QOL questionnaire at baseline, during treatment, and every 6 months through 36 months. FACT-B Trial Outcome Index (TOI), symptom severity, and SF-36 Vitality and Physical Functioning (PF) scales scores were compared between the two groups using a mixed model for repeated measures analysis. MH was collected at baseline and subsequently assessed if menstrual bleeding occurred within 12 months prior to randomization. Post-chemotherapy amenorrhea outcome was examined at 18 months and was defined as lack of menses in the preceding year. Logistic regression was used to test for association of amenorrhea and treatment. CF assessment was done at baseline and 12 months. Correlation analysis was used to address associations between changes in baseline and 12-month PF and concurrent CF changes measured by LVEF. RESULTS: FEC-100 patients had statistically significantly lower TOI scores during chemotherapy (P = 0.02) and at 6 months (P < 0.001); lower Vitality score at 6 months (P < 0.01), and lower PF score during the first year than AC patients. There were no statistically significant QOL score differences between the two groups beyond 12 months. No significant differences in symptom severity between the two groups were observed. Rates of amenorrhea were significantly different between FEC-100 and AC (67.4% vs. 59.1%, P < 0.001). There was no association between changes in LVEF and PF (P = 0.38). CONCLUSIONS: Statistically significant QOL differences between the two groups favored AC; however, the magnitude was small and unlikely to be clinically meaningful. There was a clinical and statistically significant difference in risk for amenorrhea, favoring AC. TRIAL REGISTRY: NCT00087178; Date of registration: 07/08/2004.

RESUMO

PURPOSE: Younger women are at risk for depression and related symptoms following breast cancer. The Pathways to Wellness study, a randomized, multi-institution, three-arm trial, tested the efficacy of two behavioral interventions for younger breast cancer survivors with elevated depressive symptoms: mindful awareness practices (MAPs) and survivorship education (SE) (Clincaltrials.gov identifier: NCT03025139). METHODS: Women diagnosed with breast cancer at or before 50 years of age who had completed treatment and had elevated depressive symptoms were randomly assigned to 6 weeks of MAPs, SE, or wait-list control (WLC). Assessments were conducted preintervention and postintervention and at 3-month and 6-month postintervention follow-ups. Analyses compared each intervention to WLC using linear mixed models. The primary outcome was change in depressive symptoms from preintervention to postintervention on the Center for Epidemiologic Studies-Depression Scale; secondary outcomes included change in fatigue, insomnia, and vasomotor symptoms. RESULTS: Two hundred forty-seven women (median age = 46 years) were randomly assigned to MAPs (n = 85), SE (n = 81), or WLC (n = 81). MAPs and SE led to significant decreases in depressive symptoms from preintervention to postintervention relative to WLC (mean change relative to WLC [95% CI]: MAPs, -4.7 [-7.5 to -1.9]; SE, -4.0 [-6.9 to -1.1]), which persisted at 6-month follow-up for MAPs (mean change relative to WLC [95% CI]: MAPs, -3.7 [-6.6 to -0.8]; SE, -2.8 [-5.9 to 0.2]). MAPs, but not SE, also had beneficial effects on fatigue, insomnia, and vasomotor symptoms that persisted at 6-month follow-up (P < .05). CONCLUSION: Mindfulness meditation and SE reduced depressive symptoms in younger breast cancer survivors. These interventions can be widely disseminated over virtual platforms and have significant potential benefit for quality of life and overall survivorship in this vulnerable group.

RESUMO

OBJECTIVE: Mindfulness training has been shown to improve psychological well-being and physical health. One proposed pathway for the positive effects of mindfulness training is through the development of new emotion regulation strategies, such as the ability to experience emotions by observing and accepting them without judgment. Theoretically, this should facilitate recovery from negative emotional states; however, this has rarely been examined empirically. The goal of the current study was to determine whether mindfulness training is associated with more efficient emotional and cardiovascular recovery from induced negative affect. METHODS: The current study tested emotional and cardiovascular recovery from induced negative affect during a personal recall task in women randomly assigned to 6-weeks of mindfulness training (n=39) compared to women assigned to a wait-list control condition (n=32). During baseline, task, and post-task rest, blood pressure and heart rate were monitored at fixed intervals and heart rate variability (HRV) and pre-ejection period (PEP) were monitored continuously. This study was embedded within a randomized trial that evaluated the effects of mindfulness training in a sample of younger breast cancer survivors, a group in need of access to effective psychosocial intervention as they can experience high stress, anxiety, and physical symptoms for many years in to survivorship. RESULTS: In response to the personal recall task, women in both the intervention and control groups showed significant increases in sadness, anxiety, and anger, with the intervention group reaching higher levels of sadness and anger than controls. Further, the intervention group showed a significantly steeper decline in sadness and anger, as well as steeper initial decline in diastolic blood pressure compared to women in the wait list control condition. Groups did not differ in their self-reported feelings of anxiety, or in blood pressure, heart rate, or pre-ejection period (PEP) responses to the task. The control group demonstrated an increase in heart rate variability (HRV) during the task (indexed by the root mean square of successive differences in heart rate; RMSSD) while the intervention group remained flat throughout the task. CONCLUSION: Compared to the control group, women in the intervention group experienced greater negative emotions when recalling a difficult experience related to their breast cancer, and demonstrated an efficient emotional and blood pressure recovery from the experience. This suggests that mindfulness training may lead to an enhanced emotional experience coupled with the ability to recovery quickly from negative emotional states.

RESUMO

Purpose Cognitive behavioral therapy for insomnia (CBT-I) and Tai Chi Chih (TCC), a movement meditation, improve insomnia symptoms. Here, we evaluated whether TCC is noninferior to CBT-I for the treatment of insomnia in survivors of breast cancer. Patients and Methods This was a randomized, partially blinded, noninferiority trial that involved survivors of breast cancer with insomnia who were recruited from the Los Angeles community from April 2008 to July 2012. After a 2-month phase-in period with repeated baseline assessment, participants were randomly assigned to 3 months of CBT-I or TCC and evaluated at months 2, 3 (post-treatment), 6, and 15 (follow-up). Primary outcome was insomnia treatment response-that is, marked clinical improvement of symptoms by the Pittsburgh Sleep Quality Index-at 15 months. Secondary outcomes were clinician-assessed remission of insomnia; sleep quality; total sleep time, sleep onset latency, sleep efficiency, and awake after sleep onset, derived from sleep diaries; polysomnography; and symptoms of fatigue, sleepiness, and depression. Results Of 145 participants who were screened, 90 were randomly assigned (CBT-I: n = 45; TCC: n = 45). The proportion of participants who showed insomnia treatment response at 15 months was 43.7% and 46.7% in CBT-I and TCC, respectively. Tests of noninferiority showed that TCC was noninferior to CBT-I at 15 months ( P = .02) and at months 3 ( P = .02) and 6 ( P < .01). For secondary outcomes, insomnia remission was 46.2% and 37.9% in CBT-I and TCC, respectively. CBT-I and TCC groups showed robust improvements in sleep quality, sleep diary measures, and related symptoms (all P < .01), but not polysomnography, with similar improvements in both groups. Conclusion CBT-I and TCC produce clinically meaningful improvements in insomnia. TCC, a mindful movement meditation, was found to be statistically noninferior to CBT-I, the gold standard for behavioral treatment of insomnia.

RESUMO

OBJECTIVE: Mindfulness meditation reduces psychological distress among individuals with cancer. However, mechanisms for intervention effects have not been fully determined. This study tested emotion regulation strategies as mediators of intervention effects in a sample of younger women treated for breast cancer, a group at risk for psychological distress. We focused on two distinct strategies targeted by the intervention-rumination and self-kindness-and further examined the broader construct of mindfulness as a potential mediator. METHOD: Women (n = 71) with Stage 0-III breast cancer diagnosed at or before age 50 who had completed cancer treatment were randomly assigned to a 6-week mindfulness intervention or wait-list control group. Assessments occurred at study entry, postintervention, and a 3-month follow-up. RESULTS: In single mediator analyses, increases in self-kindness (CIB [-7.83, -1.93]), decreases in rumination (CIB [-5.05, -.31]), and increases in mindfulness (CIB [-6.58, -.82]) each mediated reductions in depressive symptoms from pre- to postintervention. Increases in self-kindness also mediated reductions in perceived stress (CIB [-5.37, -.62]) from pre- to postintervention, and increases in self-kindness (CIB [-5.67, -.22]) and in mindfulness (CIB [-5.51, -.16]) each mediated intervention effects on perceived stress from preintervention to 3-month follow-up. In multiple mediator analysis, only self-kindness mediated intervention effects on depressive symptoms from pre- to postintervention (CIB [-6.41, -.61]), and self-kindness and mindfulness together mediated intervention effects on perceived stress from preintervention to follow-up (CIB [-6.77, -.35]). CONCLUSIONS: Self-kindness played a consistent role in reducing distress in younger women with breast cancer. The efficacy of this understudied emotion regulation strategy should be evaluated in other clinical populations. (PsycINFO Database Record

RESUMO

PURPOSE: Survivorship care plans (SCPs) have been suggested to reduce fragmentation of care experienced by cancer survivors. Acceptance of SCPs is high, but trials in the United States are few. This pilot study used a quasiexperimental design to examine the outcomes achieved by breast cancer survivors receiving a standardized SCP visit at one of seven comprehensive cancer centers. MATERIALS AND METHODS: Outcomes were assessed before and again 3 months after delivery of an SCP and included survivors' use of and satisfaction with SCPs, perceived knowledge about survivorship, and assessment of the quality and coordination of survivorship care. RESULTS: One hundred thirty-nine survivors of breast cancer completed baseline and follow-up measures and received a standardized SCP visit. Participants most commonly used SCP materials to make decisions about exercise (64%), which tests to receive and when (62%), and dietary changes (62%). Only 21% shared the SCP with their primary care provider during that time. Satisfaction with the SCP was high, with 90% of participants reporting being at least satisfied with the SCP. Perceived knowledge about survivorship improved after SCP delivery, as did perceived care coordination and the provider's knowledge of the effects of cancer on survivors (all P < .001). Individuals closer to the time of diagnosis reported greater satisfaction with and use of SCPs. CONCLUSION: This study demonstrates improvements in perceived knowledge and quality of survivorship care after receipt of a comprehensive SCP. Survivors were satisfied with their SCP, and those closer to diagnosis reported greater satisfaction with and use of the materials.

RESUMO

Supportive care and palliative care are now recognised as critical components of global cancer control programmes. Many aspects of supportive and palliative care services are already available in some low-income and middle-income countries. Full integration of supportive and palliative care into breast cancer programmes requires a systematic, resource-stratified approach. The Breast Health Global Initiative convened three expert panels to develop resource allocation recommendations for supportive and palliative care programmes in low-income and middle-income countries. Each panel focused on a specific phase of breast cancer care: during treatment, after treatment with curative intent (survivorship), and after diagnosis with metastatic disease. The panel consensus statements were published in October, 2013. This Executive Summary combines the three panels' recommendations into a single comprehensive document covering breast cancer care from diagnosis through curative treatment into survivorship, and metastatic disease and end-of-life care. The recommendations cover physical symptom management, pain management, monitoring and documentation, psychosocial and spiritual aspects of care, health professional education, and patient, family, and caregiver education.

RESUMO

BACKGROUND: Premenopausal women diagnosed with breast cancer are at risk for psychological and behavioral disturbances after cancer treatment. Targeted interventions are needed to address the needs of this vulnerable group. METHODS: This randomized trial provided the first evaluation of a brief, mindfulness-based intervention for younger breast cancer survivors designed to reduce stress, depression, and inflammatory activity. Women diagnosed with early stage breast cancer at or before age 50 who had completed cancer treatment were randomly assigned to a 6-week Mindful Awareness Practices (MAPS) intervention group (n = 39) or to a wait-list control group (n = 32). Participants completed questionnaires before and after the intervention to assess stress and depressive symptoms (primary outcomes) as well as physical symptoms, cancer-related distress, and positive outcomes. Blood samples were collected to examine genomic and circulating markers of inflammation. Participants also completed questionnaires at a 3-month follow-up assessment. RESULTS: In linear mixed models, the MAPS intervention led to significant reductions in perceived stress (P = .004) and marginal reductions in depressive symptoms (P = .094), as well as significant reductions in proinflammatory gene expression (P = .009) and inflammatory signaling (P = .001) at postintervention. Improvements in secondary outcomes included reduced fatigue, sleep disturbance, and vasomotor symptoms and increased peace and meaning and positive affect (P < .05 for all). Intervention effects on psychological and behavioral measures were not maintained at the 3-month follow-up assessment, although reductions in cancer-related distress were observed at that assessment. CONCLUSIONS: A brief, mindfulness-based intervention demonstrated preliminary short-term efficacy in reducing stress, behavioral symptoms, and proinflammatory signaling in younger breast cancer survivors.

RESUMO

Cancer-related fatigue is a common and often long lasting symptom for many breast cancer survivors. Fatigued survivors show evidence of elevated inflammation, but the physiological mechanisms driving inflammatory activity have not been determined. Alterations in the autonomic nervous system, and particularly parasympathetic nervous system activity, are a plausible, yet understudied contributor to cancer-related fatigue. The goal of this study was to replicate one previous study showing an association between lower parasympathetic activity and higher fatigue in breast cancer survivors (Fagundes et al., 2011), and to examine whether inflammation mediates this association. Study participants were drawn from two samples and included 84 women originally diagnosed with early stage breast cancer prior to age 50. Participants completed questionnaires, provided blood samples for determination of interleukin (IL)-6 and C-reactive protein (CRP), and underwent electrocardiography (ECG) assessment for evaluation of resting heart rate variability (HRV), a measure of parasympathetic activity. Results showed that lower HRV was associated with higher fatigue (p<.05), as predicted. In bivariate analyses, HRV was also correlated with circulating concentrations of IL-6 and CRP. However, path analyses did not support inflammation as a mediator of the association between HRV and fatigue; instead, associations among these variables appeared to be driven by age and BMI. These findings identify HRV as a potential contributor to cancer-related fatigue, but suggest that inflammation does not mediate this association in younger, healthy breast cancer survivors who are several years post-treatment. The autonomic nervous system merits additional attention in research on the etiology of cancer-related fatigue.

RESUMO

PURPOSE: This guideline presents screening, assessment, and treatment approaches for the management of adult cancer survivors who are experiencing symptoms of fatigue after completion of primary treatment. METHODS: A systematic search of clinical practice guideline databases, guideline developer Web sites, and published health literature identified the pan-Canadian guideline on screening, assessment, and care of cancer-related fatigue in adults with cancer, the National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines In Oncology (NCCN Guidelines) for Cancer-Related Fatigue and the NCCN Guidelines for Survivorship. These three guidelines were appraised and selected for adaptation. RESULTS: It is recommended that all patients with cancer be evaluated for the presence of fatigue after completion of primary treatment and be offered specific information and strategies for fatigue management. For those who report moderate to severe fatigue, comprehensive assessment should be conducted, and medical and treatable contributing factors should be addressed. In terms of treatment strategies, evidence indicates that physical activity interventions, psychosocial interventions, and mind-body interventions may reduce cancer-related fatigue in post-treatment patients. There is limited evidence for use of psychostimulants in the management of fatigue in patients who are disease free after active treatment. CONCLUSION: Fatigue is prevalent in cancer survivors and often causes significant disruption in functioning and quality of life. Regular screening, assessment, and education and appropriate treatment of fatigue are important in managing this distressing symptom. Given the multiple factors contributing to post-treatment fatigue, interventions should be tailored to each patient's specific needs. In particular, a number of nonpharmacologic treatment approaches have demonstrated efficacy in cancer survivors.

RESUMO

BACKGROUND: Yoga is a popular mind-body therapy that has demonstrated beneficial effects on psychological, behavioral, and functional outcomes. However, few studies have investigated effects on inflammatory processes. This study tested the hypothesis that an Iyengar yoga intervention specifically designed for fatigued breast cancer survivors would lead to decreases in inflammation-related gene expression and circulating markers of proinflammatory cytokine activity. METHODS: Breast cancer survivors with persistent cancer-related fatigue were randomized to a 12-week Iyengar yoga intervention (n=16) or a 12-week health education control condition (n=15). Blood samples were collected at baseline, post-intervention, and at a 3-month follow-up for genome-wide transcriptional profiling and bioinformatic analyses. Plasma inflammatory markers and salivary cortisol were also assessed. RESULTS: In promoter-based bioinformatics analyses, the yoga group showed reduced activity of the pro-inflammatory transcription factor nuclear factor kappa B (NF-κB), increased activity of the anti-inflammatory glucocorticoid receptor, and reduced activity of cAMP response element-binding protein (CREB) family transcription factors relative to controls (all ps<.05). There was also a significant intervention effect on the soluble tumor necrosis factor receptor type II (sTNF-RII), a marker of TNF activity; plasma levels of sTNF-RII remained stable in the yoga group, whereas levels of this marker increased in the health education group (p=.028). A similar, non-significant trend was observed for the interleukin 1 receptor antagonist (p=.16). No significant changes in C reactive protein (CRP), interleukin 6 (IL-6), or diurnal cortisol measures were observed. CONCLUSIONS: A 12-week restorative Iyengar yoga intervention reduced inflammation-related gene expression in breast cancer survivors with persistent fatigue. These findings suggest that a targeted yoga program may have beneficial effects on inflammatory activity in this patient population, with potential relevance for behavioral and physical health.

RESUMO

BACKGROUND: Mind-body therapies such as Tai Chi are widely used by breast cancer survivors, yet effects on inflammation are not known. This study hypothesized that Tai Chi Chih (TCC) would reduce systemic, cellular, and genomic markers of inflammation as compared with cognitive behavioral therapy for insomnia (CBT-I). METHODS: In this randomized trial for the treatment of insomnia, 90 breast cancer survivors with insomnia were assigned to TCC or CBT-I for 2-hour sessions weekly for 3 months. At baseline and postintervention, blood samples were obtained for measurement of C-reactive protein and toll-like receptor-4-activated monocyte production of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF), with a random subsample (n = 48) analyzed by genome-wide transcriptional profiling. RESULTS: Levels of C-reactive protein did not change in the TCC and CBT-I groups. Levels of toll-like receptor-4-activated monocyte production of IL-6 and TNF combined showed an overall reduction in TCC versus CBT-I (P < .02), with similar effects for IL-6 (P = .07) and TNF (P < .05) alone. For genome-wide transcriptional profiling of circulating peripheral blood mononuclear cells, expression of genes encoding proinflammatory mediators showed an overall reduction in TCC versus CBT-I (P = .001). TELiS promoter-based bioinformatics analyses implicated a reduction of activity of the proinflammatory transcription factor, nuclear factor-κB, in structuring these differences. CONCLUSIONS: Among breast cancer survivors with insomnia, 3 months of TCC reduced cellular inflammatory responses, and reduced expression of genes encoding proinflammatory mediators. Given the link between inflammation and cancer, these findings provide an evidence-based molecular framework to understand the potential salutary effects of TCC on cancer survivorship.

RESUMO

Low serum vitamin D levels have been associated with poor outcomes in women diagnosed with early breast cancer. However, no randomized controlled trials (RCTs) have been performed to determine whether vitamin D supplementation might be an effective intervention in this population. We prospectively evaluated vitamin D adequacy and supplementation rates in a contemporary cross-sectional sample of breast cancer patients from 2 large urban centers and examined the feasibility of an RCT of vitamin D supplementation. Women with recently diagnosed early breast cancer were prospectively identified and recruited in Toronto and Los Angeles between March 2009 and January 2010. Anthropometric measurements, dietary, lifestyle, and medication histories were obtained by means of structured questionnaires and interviews. Tumor and treatment characteristics were abstracted from clinical records and blood samples were collected for analysis of 25-OH vitamin D. 173 eligible patients (median age 57) were enrolled. Clinical and treatment characteristics were similar between centres. 84.4 % of women reported use of vitamin D-containing supplements with median daily doses of 1,400 IU. Median 25-OH vitamin D levels were 85.5 and 98.5 nmol/L (P = 0.1), and levels of deficiency (<50 nmol/L), insufficiency (50-72 nmol/L), and adequacy (>72 nmol/L) were 3.8, 23.8, 72.5 % (Toronto) and 4.3, 20.7, 75 % (Los Angeles). 25-OH vitamin D levels were strongly correlated with vitamin D supplement use (r = 0.41, P < 0.0001). 68 % of women expressed willingness to participate in a vitamin D supplementation RCT; however, only 12.7 % of the study population met the pre-specified feasibility criteria (25-OH vitamin D <72 nmol/L, willing to participate, and taking ≤1,000 IU vitamin D supplement/day). Both vitamin D levels and supplementation rates are higher than in previous reports. While the majority of women would be willing to participate in an RCT of vitamin D supplementation, low levels of deficiency/insufficiency and high rates of supplement use would limit the feasibility of such a study.

RESUMO

BACKGROUND: Neurotoxicity from adjuvant treatment with oxaliplatin has been studied in patients with colorectal carcinoma in short-term studies, but, to the authors' knowledge, the current article is the first long-term assessment which reports the National Surgical Adjuvant Breast and Bowel Project (NSABP) investigation of whether excess neurotoxicity persists beyond 4 years. METHODS: As part of a colorectal cancer long-term survivor study (LTS-01), long-term neurotoxicity was assessed in 353 patients on NSABP Protocol C-07 (cross-sectional sample). Ninety-two of these patients from LTS-01 also had longitudinal data and were reassessed 5 to 8 years (median, 7 years) after random assignment (longitudinal sample). Contingency tables compared cohorts, a mixed model compared neurotoxicity between treatments over time, and a Wilcoxon rank-sum test compared neurotoxicity between treatments (cross-sectional sample). RESULTS: In the cross-sectional sample, the increase in mean total neurotoxicity scores of 1.8 with oxaliplatin was statistically significant (P = .005), but not clinically significant (a minimally important difference of 4 was reported at the long-term assessment). Patients who received oxaliplatin had increased odds of numbness and tingling in hands (odds ratio, 2.00; P = .015) and feet (odds ratio, 2.78; P < .001) versus patients who did not receive oxaliplatin. The magnitude of the oxaliplatin effect varied with time (P < .001) in the longitudinal sample, such that the oxaliplatin-treated group did not have significantly greater total neurotoxicity scores by 7 years. CONCLUSIONS: At the long-term endpoint, there was no clinically significant increase in total neurotoxicity scores for patients who received oxaliplatin, but the specific neurotoxicities of numbness and tingling of the hands and feet remained significantly elevated for oxaliplatin-treated patients.

RESUMO

BACKGROUND: Cancer-related fatigue afflicts up to 33% of breast cancer survivors, yet there are no empirically validated treatments for this symptom. METHODS: The authors conducted a 2-group randomized controlled trial to determine the feasibility and efficacy of an Iyengar yoga intervention for breast cancer survivors with persistent post-treatment fatigue. Participants were breast cancer survivors who had completed cancer treatments (other than endocrine therapy) at least 6 months before enrollment, reported significant cancer-related fatigue, and had no other medical conditions that would account for fatigue symptoms or interfere with yoga practice. Block randomization was used to assign participants to a 12-week, Iyengar-based yoga intervention or to 12 weeks of health education (control). The primary outcome was change in fatigue measured at baseline, immediately post-treatment, and 3 months after treatment completion. Additional outcomes included changes in vigor, depressive symptoms, sleep, perceived stress, and physical performance. Intent-to-treat analyses were conducted with all randomized participants using linear mixed models. RESULTS: Thirty-one women were randomly assigned to yoga (n = 16) or health education (n = 15). Fatigue severity declined significantly from baseline to post-treatment and over a 3-month follow-up in the yoga group relative to controls (P = .032). In addition, the yoga group had significant increases in vigor relative to controls (P = .011). Both groups had positive changes in depressive symptoms and perceived stress (P < .05). No significant changes in sleep or physical performance were observed. CONCLUSIONS: A targeted yoga intervention led to significant improvements in fatigue and vigor among breast cancer survivors with persistent fatigue symptoms.

RESUMO

INTRODUCTION: This study evaluates the concordance of treatment summaries (TSs) and survivorship care plans (SCPs) delivered to breast cancer survivors within the LIVESTRONG™ Network of Survivorship Centers of Excellence with Institute of Medicine (IOM) recommendations and describes additional structure/process variables. METHOD: Seven NCI-designated comprehensive cancer centers and six community-based centers participated. TS/SCPs for 65 patients were rated against IOM recommendations using a study-derived checklist, and surveys were administered to better understand the structure and process of delivering TSs/SCPs. RESULTS: On average, fewer than half of IOM content recommendations were met for TSs (M = 46%) and less than two thirds for SCPs (M = 59%). No sites achieved ≥75% overall concordance with IOM recommendations for TSs and only two of 13 met this criterion for SCPs. Content domain scores across sites varied widely, as did the number of sites addressing domain content with ≥75% concordance. Nonetheless, resources required for document preparation and delivery were substantial. DISCUSSION: Gaps in concordance with IOM recommendations exist even in dedicated survivorship centers. A substantial time burden was also noted. Further research is needed to determine which informational elements are essential, to develop and test strategies for improving efficiency and reach, and to determine if outcomes of survivorship care planning warrant the resources required in their preparation and delivery. IMPLICATIONS FOR SURVIVORS: TSs and SCPs have been recommended for all cancer survivors. Essential elements must be determined, approaches made more efficient, outcome improvements demonstrated, and cost-benefit analyses determined before survivors should expect widespread implementation of this recommendation for survivorship care.

RESUMO

BACKGROUND: The objectives of this study were to characterize survivorship models of care across eight LIVESTRONG Survivorship Center of Excellence (COE) Network sites and to identify barriers and facilitators influencing survivorship care. METHODS: Using the framework of the Chronic Care Model (CCM), quantitative and qualitative methods of inquiry were conducted with the COEs. Methods included document reviews, key informant telephone interviews with 39 participants, online Assessment of Chronic Illness Care (ACIC) surveys with 40 participants, and three site visits. RESULTS: Several overarching themes emerged in qualitative interviews and were substantiated by quantitative methods. Health system factors supporting survivorship care include organization and leadership commitment and program champions at various levels of the health care team. System barriers include reimbursement issues, lack of space, and the need for leadership commitment to support changes in clinical practices as well as having program "champions" among clinical staff. Multiple models of care include separate survivorship clinics and integrated models as well as consultative models. COEs' scores on the ACIC survey showed overall "reasonable support" for survivorship care; however, the clinical information system domain was least developed. Although the ACIC findings indicated "reasonable support" for self-management, the qualitative analysis revealed that self-management support was largely limited to health promotion provided in clinic-based education and counseling sessions, with few COEs providing patients with self-management tools and interventions. CONCLUSIONS: The CCM framework captured experiences and challenges of these COEs and provided insight into the current state of survivorship care in the context of National Cancer Institute-designated comprehensive cancer centers. Findings showed that cancer patients and providers could benefit from clinical information systems that would better identify candidates for survivorship care and provide timely information. In addition, a crucial area for development is self-management support outside of clinical care. IMPLICATIONS FOR CANCER SURVIVORS: Cancer survivors may benefit from learning about the experience and challenges faced by the eight LIVESTRONG Centers of Excellence in developing programs and models for cancer survivorship care, and these findings may inform patient and caregiver efforts to seek, evaluate, and advocate for quality survivorship programs designed to meet their needs.
