Psychological effects and mediators of a group multi-component program for breast cancer survivors

Beyond breast cancer: An exploration of the experiences of middle-aged female breast cancer survivors in Australia

OBJECTIVES

Middle-aged women (i.e., aged 40-65 years) who live with, through and beyond breast cancer (survivors) are an under-researched population, particularly within an Australian context. The unmet needs reported within this population include fatigue, psychological distress, body image concerns, early-onset menopause, and a lack of information on these issues. This study explores how the experiences of breast cancer survivorship impact the lives of Australian middle-aged women.

STUDY DESIGN

Qualitative analysis of written comments in an open text field of a survey completed by 644 women reporting breast cancer in the middle-aged cohort of the Australian Longitudinal Study of Women's Health gathered between 1996 and 2013. Data was collected from any participants who reported breast cancer in any survey. Researchers conducted a thematic analysis using consensus coding on data and identified key themes.

MAIN OUTCOME MEASURES

Any data where participants described their experiences of breast cancer survivorship.

RESULTS

This cohort reported a unique experience of breast cancer survivorship due to their age group. Analysis developed the following themes: the middle-aged context of breast cancer; care and support, body changes, overcoming fears and maintaining balance; and finding a 'new normal'.

CONCLUSIONS

Breast cancer survivorship is a diverse experience. For many it involves chronic limitations and challenges. Investigation and application of survivorship care plans in Australia could benefit breast cancer survivors by including multidisciplinary health professionals in their care. Unmet needs and psychological distress were described by participants rather than biomedical concerns. Further recommendations include development of online support groups providing access to rehabilitation professionals, especially for otherwise isolated rural women.

Types of Social Support Predicting Physical Activity and Quality of Life in Group Exercise Programs for Adults Living with Cancer

Social support (SS) and physical activity (PA) can improve quality of life (QoL) in cancer, meaning group PA programs are important for rehabilitation. However, there are many types of SS, and few studies have compared which SS concepts are more strongly associated with PA and QoL. This exploratory cross-sectional study examined the association between several types of SS provided by other people in group exercise oncology classes and PA and QoL among adults living with cancer. It was hypothesized all types of SS would be positively associated with PA and QoL. Participants (N = 72) completed a questionnaire assessing 11 SS predictors, five QoL outcomes, and one self-reported PA outcome, and wore a Fitbit to assess step count for 1 week. Hypotheses were tested using multiple regression. Reassurance of worth support predicted self-reported moderate-to-vigorous PA (R2 = .07, p = .03). Relatedness thwarting negatively predicted general (R2 = .07, p = .03) and social well-being (R2 = .10, p = .01). Social network predicted physical well-being (R2 = .07, F(1, 66) = 4.93, p = .03). There were no significant SS predictors of the other outcomes. Group exercise oncology programs should train instructors to promote reassurance of worth by recognizing or facilitating other participants to recognize participants' PA competence and skills, encourage developing social relationships by creating opportunities to connect over time, and minimize relatedness thwarting by promoting belonging and inclusion. Future research should compare different types of SS in larger samples and diverse populations of adults living with cancer.

Non-medical interventions to enhance return to work for people with cancer

BACKGROUND

People with cancer are 1.4 times more likely to be unemployed than people without a cancer diagnosis. Therefore, it is important to investigate whether programmes to enhance the return-to-work (RTW) process for people who have been diagnosed with cancer are effective. This is an update of a Cochrane review first published in 2011 and updated in 2015.

OBJECTIVES

To evaluate the effectiveness of non-medical interventions aimed at enhancing return to work (RTW) in people with cancer compared to alternative programmes including usual care or no intervention.

SEARCH METHODS

We searched CENTRAL (the Cochrane Library), MEDLINE, Embase, CINAHL, PsycINFO and three trial registers up to 18 August 2021. We also examined the reference lists of included studies and selected reviews, and contacted authors of relevant studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and cluster-RCTs on the effectiveness of psycho-educational, vocational, physical or multidisciplinary interventions enhancing RTW in people with cancer. The primary outcome was RTW measured as either RTW rate or sick leave duration measured at 12 months' follow-up. The secondary outcome was quality of life (QoL).

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed RCTs for inclusion, extracted data and rated certainty of the evidence using GRADE. We pooled study results judged to be clinically homogeneous in different comparisons reporting risk ratios (RRs) with 95% confidence intervals (CIs) for RTW and mean differences (MD) or standardised mean differences (SMD) with 95% CIs for QoL.

MAIN RESULTS

We included 15 RCTs involving 1477 people with cancer with 19 evaluations because of multiple treatment groups. In this update, we added eight new RCTs and excluded seven RCTs from the previous versions of this review that were aimed at medical interventions. All included RCTs were conducted in high-income countries, and most were aimed at people with breast cancer (nine RCTs) or prostate cancer (two RCTs). Risk of bias We judged nine RCTs at low risk of bias and six at high risk of bias. The most common type of bias was a lack of blinding (9/15 RCTs). Psycho-educational interventions We found four RCTs comparing psycho-educational interventions including patient education and patient counselling versus care as usual. Psycho-educational interventions probably result in little to no difference in RTW compared to care as usual (RR 1.09, 95% CI 0.96 to 1.24; 4 RCTs, 512 participants; moderate-certainty evidence). This means that in the intervention and control groups, approximately 625 per 1000 participants may have returned to work. The psycho-educational interventions may result in little to no difference in QoL compared to care as usual (MD 1.47, 95% CI -2.38 to 5.32; 1 RCT, 124 participants; low-certainty evidence). Vocational interventions We found one RCT comparing vocational intervention versus care as usual. The evidence was very uncertain about the effect of a vocational intervention on RTW compared to care as usual (RR 0.94, 95% CI 0.78 to 1.13; 1 RCT, 34 participants; very low-certainty evidence). The study did not report QoL. Physical interventions Four RCTs compared a physical intervention programme versus care as usual. These physical intervention programmes included walking, yoga or physical exercise. Physical interventions likely increase RTW compared to care as usual (RR 1.23, 95% CI 1.08 to 1.39; 4 RCTs, 434 participants; moderate-certainty evidence). This means that in the intervention group probably 677 to 871 per 1000 participants RTW compared to 627 per 1000 in the control group (thus, 50 to 244 participants more RTW). Physical interventions may result in little to no difference in QoL compared to care as usual (SMD -0.01, 95% CI -0.33 to 0.32; 1 RCT, 173 participants; low-certainty evidence). The SMD translates back to a 1.8-point difference (95% CI -7.54 to 3.97) on the European Organisation for Research and Treatment of Cancer Quality of life Questionnaire Core 30 (EORTC QLQ-C30). Multidisciplinary interventions Six RCTs compared multidisciplinary interventions (vocational counselling, patient education, patient counselling, physical exercises) to care as usual. Multidisciplinary interventions likely increase RTW compared to care as usual (RR 1.23, 95% CI 1.09 to 1.33; 6 RCTs, 497 participants; moderate-certainty evidence). This means that in the intervention group probably 694 to 844 per 1000 participants RTW compared to 625 per 1000 in the control group (thus, 69 to 217 participants more RTW). Multidisciplinary interventions may result in little to no difference in QoL compared to care as usual (SMD 0.07, 95% CI -0.14 to 0.28; 3 RCTs, 378 participants; low-certainty evidence). The SMD translates back to a 1.4-point difference (95% CI -2.58 to 5.36) on the EORTC QLQ-C30.

AUTHORS' CONCLUSIONS

Physical interventions (four RCTs) and multidisciplinary interventions (six RCTs) likely increase RTW of people with cancer. Psycho-educational interventions (four RCTs) probably result in little to no difference in RTW, while the evidence from vocational interventions (one RCT) is very uncertain. Psycho-educational, physical or multidisciplinary interventions may result in little to no difference in QoL. Future research on enhancing RTW in people with cancer involving multidisciplinary interventions encompassing a physical, psycho-educational and vocational component is needed, and be preferably tailored to the needs of the patient.

Effectiveness of Digital Health on the Quality of Life of Long-Term Breast Cancer Survivors: A Systematic Review

OBJECTIVES

To identify, critically appraise, and synthesize the available evidence on the effectiveness of digital health interventions to improve the quality of life or any of its four dimensions (physical, psychological, social, and spiritual) in women survivors of breast cancer who are in the extended or permanent survival stage.

DATA SOURCES

Systematic review-Four databases were searched: PubMed, CINAHL, PsycINFO, and Web of Science.

CONCLUSION

The clinical evidence shows a positive relationship or association between eHealth use and improved quality of life in breast cancer survivors at extended or permanent survival stage. However, the findings point to a deficit in the assessment of the social and spiritual domains that play a fundamental role in the quality of life of survivors.

IMPLICATION FOR NURSING PRACTICE

The findings found reflect implications of great value for nursing practice because these professionals are the main users of digital health tools to provide them to patients. Using these digital tools contributes to improving evidence-based practice and providing greater efficiency and effectiveness in the care of long-term cancer survivors.

Effect of Psychosocial, Behavioral, and Disease Characteristics on Health-Related Quality of Life (HRQoL) After Breast Cancer Surgery: A Cross-Sectional Study of a Regional Australian Population

BACKGROUND

 Increasing long-term breast cancer survivorship has highlighted the importance of patient-reported outcomes such as health-related quality of life (HRQoL) in addition to traditional outcomes that were used to define successful operative management. This study aimed to describe HRQoL in patients who underwent breast cancer resection in a regional Australian setting and identify the psychosocial, demographic, and operative characteristics associated with poor HRQoL.

METHODS

 Consecutive patients who underwent breast cancer resection between 2015 and 2022 were included. Patients were asked to complete a survey instrument that included validated measures of HRQoL, emotional distress, fear of cancer recurrence (FCR), and social support. Demographic, disease, and operative data were collected from the medical record of the respondents.

RESULTS

 Forty-six patients completed the survey (100% female, mean age = 62.68 years). Most HRQoL domains were significantly lower than an Australian reference population. HRQoL was more strongly associated with psychosocial factors (emotional distress, FCR, and social support) but was also associated with socioeconomic status, stage of cancer at presentation, and surgical complications. HRQoL was not related to breast conservation, management of the Axilla, or time since operation.

CONCLUSION

 Long-term changes in HRQoL should be considered during the management and surveillance of breast cancer patients in regional Australia.

Community-based interventions designed to optimize health behaviors among cancer survivors: an integrative systematic review

PURPOSE

The purpose of this review was to synthesize the evidence on community-based health behavior optimization interventions (physical activity, nutrition, weight management) with a focus on cancer survivors at risk for poor health outcomes.

METHODS

This integrative review followed the methods and protocol outlined by the Joanna Briggs Institute Methods Manual for systematic reviews and was reported using PRISMA-Scr. Four databases, namely, PubMed, CINAHL, Web of Science, SportDiscus, were searched in March 2021 to identify articles addressing health behaviors among cancer survivors.

RESULTS

The review included 43 articles describing unique interventions developed through community-based participatory research (CBPR). The majority of community-based interventions were designed to optimize exercise/physical activity (76.7%) exclusively or in combination with nutrition. Non-Hispanic White persons constituted most participants. Most interventions took place as a part of an established community program and recruited from existing community programs to evaluate intervention effects on specific health outcomes. Of the interventions, 88.3% improved at least one outcome measurement.

CONCLUSION

The current studies have built on the strengths and resources of the community using existing programs. There was a lack of diversity in socioeconomic status and racial/ethnic background among participants of most interventions and inputs from partners such as cancer survivors, community, and healthcare organizations. Multiple health behavior interventions with longitudinal studies are needed for racial/ethnic minoritized cancer survivors. Future research should focus on achieving mutual benefits through iterative processes to develop sustainable community/research partnerships, ensuring long-term commitment, and disseminating knowledge gained from CBPR to and by all involved partners to improve health behaviors.

Community-based exercise programs for cancer survivors: A scoping review of program characteristics using the Consolidated Framework for Implementation Research

OBJECTIVE

To describe the characteristics of exercise programs for cancer survivors conducted outside of a research laboratory (i.e., home-based, or community-based settings).

DATA SOURCES

A systematic search of published literature was conducted using Medline, Pubmed, CINAHL, PsychINFO, SPORTdiscus, and Embase from 1980 to January 2021. Where conference abstracts were identified, authors were contacted for other articles.

STUDY SELECTION

Two independent reviewers screened titles and abstracts, and full texts of potentially relevant studies with discrepancies resolved by discussion. Included studies were reports of exercise programs or interventions in which participants exercise at home, or in a community-based setting, and including individuals diagnosed with cancer either undergoing treatment or who had completed treatment.

DATA EXTRACTION

Data were extracted using the Oxford Implementation Index and coded under the five domains of the Consolidated Framework for Implementation Research (CFIR). Extraction and coding were completed by two independent reviewers, with discrepancies resolved through discussion. Data were synthesized narratively according to CFIR.

DATA SYNTHESIS

A total of 58 publications describing 34 individual programs from around the world were included. Of these, only 14 publications had the specific goal of reporting on program implementation and development. A variety of intervention characteristics and characteristics of individuals involved in the intervention were described. Reporting of factors related to the CFIR domains of inner setting, outer setting and implementation process were minimal.

CONCLUSIONS

This review summarizes the characteristics of existing programs that have been reported in the literature and finds that partnerships and collaboration in the inner and outer setting, and as part of the process of implementation. This review highlights key knowledge gaps to be answered in order to support the development of future community-based interventions.

Exercise interventions for people diagnosed with cancer: a systematic review of implementation outcomes

PURPOSE

Exercise is efficacious for people living after a cancer diagnosis. However, implementation of exercise interventions in real-world settings is challenging. Implementation outcomes are defined as 'the effects of deliberate and purposive actions to implement new treatments, practices, and services'. Measuring implementation outcomes is a practical way of evaluating implementation success. This systematic review explores the implementation outcomes of exercise interventions evaluated under real-world conditions for cancer care.

METHODS

Using PRISMA guidelines, an electronic database search of Medline, PsycInfo, CINAHL, Web of Science, SportsDiscus, Scopus and Cochrane Central Registry of Controlled Trials was conducted for studies published between January 2000 and February 2020. The Moving through Cancer registry was hand searched. The Implementation Outcomes Framework guided data extraction. Inclusion criteria were adult populations with a cancer diagnosis. Efficacy studies were excluded.

RESULTS

Thirty-seven articles that described 31 unique programs met the inclusion criteria. Implementation outcomes commonly evaluated were feasibility (unique programs n = 17, 54.8%) and adoption (unique programs n = 14, 45.2%). Interventions were typically delivered in the community (unique programs n = 17, 58.6%), in groups (unique programs n = 14, 48.3%) and supervised by a qualified health professional (unique programs n = 14, 48.3%). Implementation outcomes infrequently evaluated were penetration (unique programs n = 1, 3.2%) and sustainability (unique programs n = 1, 3.2%).

CONCLUSIONS

Exercise studies need to measure and evaluate implementation outcomes under real-world conditions. Robust measurement and reporting of implementation outcomes can help to identify what strategies are essential for successful implementation of exercise interventions.

IMPLICATIONS FOR CANCER SURVIVORS

Understanding how exercise interventions can be successful implemented is important so that people living after a cancer diagnosis can derive the benefits of exercise.

The Association of Social Support and Leisure Time Physical Activity With Mental Health Among Individuals With Cancer

PURPOSE

This study examined the relationship among social support, leisure time physical activity (LTPA), and mental health among people with cancer.

DESIGN

Cross-sectional study.

SETTING AND PARTICIPANTS

Using the 2017 Health Information National Trends Survey, we extracted data of 504 respondents who had been diagnosed with any of the 22 types of cancer listed in the survey questionnaire.

MEASURES

As independent variables, we assessed 3 different types of support: emotional, informational, and tangible support. As mediating and outcome variables, we measured LTPA and mental health, respectively.

ANALYSIS

Using AMOS version 22, a path analysis was conducted to measure model fit. A mediation test was then conducted using bootstrapping procedures.

RESULTS

The hypothesized model provided an acceptable fit to the data. Specifically, emotional support (b = .15, p = .005), informational support (b = .13, p = .008), tangible support (b = .12, p = .010), and LTPA (b = .14, p = .001) were significantly associated with mental health. We revealed a significant mediating effect of LPTA on the relationship between emotional support and mental health (Estimate = .037, 95% CI = .001-.098, p < .05).

CONCLUSION

Social support and LTPA played a significant role in promoting mental health among people with cancer. In particular, the results confirmed that individuals with cancer who reported receiving emotional support tended to engage in LTPA and thus reported better mental health.

Effectiveness of interventions to improve cancer treatment and follow-up care in socially disadvantaged groups

OBJECTIVE

To identify and characterize the interventions that aimed to improve cancer treatment and follow-up care in socially disadvantaged groups. To summarize the state of the art for clinicians and researchers.

METHODS

We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligible studies were randomized controlled trials and quasi-experimental studies with a control group (usual care or enhanced usual care) conducted in Organization for Economic Co-operation and Development (OECD) member countries and published until 2016.

RESULTS

Thirty-one interventions were identified, the majority of which were conducted in the United States in patients with breast cancer. Most interventions aimed to decrease social inequalities based on ethnicity/race and/or socioeconomic level, with fewer interventions targeting inequalities based on geographical area. The most frequently assessed outcomes were quality of life (n = 20) and psychosocial factors (n = 20), followed by treatment adherence or satisfaction (n = 12,), knowledge (n = 11), pain management (n = 10), and lifestyle habits (n = 3).

CONCLUSIONS

The impact of interventions designed to improve cancer treatment and follow-up care in socially disadvantages groups is multifactorial. Multicomponent-intervention approaches and cultural adaptations are common, and their effectiveness should be evaluated in the populations of interest. More interventions are needed from outside the Unite States and in patients with cancers other than breast cancer, targeting gender or geographical inequalities and addressing key outcomes such as treatment adherence or symptom management.

Physical activity for women with breast cancer after adjuvant therapy

BACKGROUND

Women with a diagnosis of breast cancer may experience short- and long-term disease and treatment-related adverse physiological and psychosocial outcomes. These outcomes can negatively impact prognosis, health-related quality of life (HRQoL), and psychosocial and physical function. Physical activity may help to improve prognosis and may alleviate the adverse effects of adjuvant therapy.

OBJECTIVES

To assess effects of physical activity interventions after adjuvant therapy for women with breast cancer.

SEARCH METHODS

We searched the Cochrane Breast Cancer Group (CBCG) Specialised Registry, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Physiotherapy Evidence Database (PEDro), SPORTDiscus, PsycINFO, ClinicalTrials.gov, and the World Health Organization (WHO) International Clinical Trials Registry Platform, on 18 September 2015. We also searched OpenGrey and Healthcare Management Information Consortium databases.

SELECTION CRITERIA

We searched for randomised and quasi-randomised trials comparing physical activity interventions versus control (e.g. usual or standard care, no physical activity, no exercise, attention control, placebo) after adjuvant therapy (i.e. after completion of chemotherapy and/or radiation therapy, but not hormone therapy) in women with breast cancer.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies, assessed risk of bias, and extracted data. We contacted trial authors to ask for additional information when needed. We calculated an overall effect size with 95% confidence intervals (CIs) for each outcome and used GRADE to assess the quality of evidence for the most important outcomes.

MAIN RESULTS

We included 63 trials that randomised 5761 women to a physical activity intervention (n = 3239) or to a control (n = 2524). The duration of interventions ranged from 4 to 24 months, with most lasting 8 or 12 weeks (37 studies). Twenty-eight studies included aerobic exercise only, 21 involved aerobic exercise and resistance training, and seven used resistance training only. Thirty studies described the comparison group as usual or standard care, no intervention, or control. One-fifth of studies reported at least 20% intervention attrition and the average physical activity adherence was approximately 77%.No data were available on effects of physical activity on breast cancer-related and all-cause mortality, or on breast cancer recurrence. Analysis of immediately postintervention follow-up values and change from baseline to end of intervention scores revealed that physical activity interventions resulted in significant small-to-moderate improvements in HRQoL (standardised mean difference (SMD) 0.39, 95% CI 0.21 to 0.57, 22 studies, 1996 women; SMD 0.78, 95% CI 0.39 to 1.17, 14 studies, 1459 women, respectively; low-quality evidence), emotional function (SMD 0.21, 95% CI 0.10 to 0.32, 26 studies, 2102 women, moderate-quality evidence; SMD 0.31, 95% CI 0.09 to 0.53, 15 studies, 1579 women, respectively; low-quality evidence), perceived physical function (SMD 0.33, 95% CI 0.18 to 0.49, 25 studies, 2129 women; SMD 0.60, 95% CI 0.23 to 0.97, 13 studies, 1433 women, respectively; moderate-quality evidence), anxiety (SMD -0.57, 95% CI -0.95 to -0.19, 7 studies, 326 women; SMD -0.37, 95% CI -0.63 to -0.12, 4 studies, 235 women, respectively; low-quality evidence), and cardiorespiratory fitness (SMD 0.44, 95% CI 0.30 to 0.58, 23 studies, 1265 women, moderate-quality evidence; SMD 0.83, 95% CI 0.40 to 1.27, 9 studies, 863 women, respectively; very low-quality evidence).Investigators reported few minor adverse events.Small improvements in physical activity interventions were sustained for three months or longer postintervention in fatigue (SMD -0.43, 95% CI -0.60 to -0.26; SMD -0.47, 95% CI -0.84 to -0.11, respectively), cardiorespiratory fitness (SMD 0.36, 95% CI 0.03 to 0.69; SMD 0.42, 95% CI 0.05 to 0.79, respectively), and self-reported physical activity (SMD 0.44, 95% CI 0.17 to 0.72; SMD 0.51, 95% CI 0.08 to 0.93, respectively) for both follow-up values and change from baseline scores.However, evidence of heterogeneity across trials was due to variation in intervention components (i.e. mode, frequency, intensity, duration of intervention and sessions) and measures used to assess outcomes. All trials reviewed were at high risk of performance bias, and most were also at high risk of detection, attrition, and selection bias. In light of the aforementioned issues, we determined that the evidence was of very low, low, or moderate quality.

AUTHORS' CONCLUSIONS

No conclusions regarding breast cancer-related and all-cause mortality or breast cancer recurrence were possible. However, physical activity interventions may have small-to-moderate beneficial effects on HRQoL, and on emotional or perceived physical and social function, anxiety, cardiorespiratory fitness, and self-reported and objectively measured physical activity. The positive results reported in the current review must be interpreted cautiously owing to very low-to-moderate quality of evidence, heterogeneity of interventions and outcome measures, imprecision of some estimates, and risk of bias in many trials. Future studies with low risk of bias are required to determine the optimal combination of physical activity modes, frequencies, intensities, and durations needed to improve specific outcomes among women who have undergone adjuvant therapy.

Why is Meaning-Centered Group Psychotherapy (MCGP) effective? Enhanced sense of meaning as the mechanism of change for advanced cancer patients

OBJECTIVES

Meaning-Centered Group Psychotherapy (MCGP) has been demonstrated to be an effective method for improving advanced cancer patients' quality of life and reducing their depression, hopelessness, and desire for hastened death. To further understand MCGP, this study examined the mechanisms of change in MCGP on these outcomes via advanced cancer patients' changes of sense of meaning and peace in life.

METHODS

The sample data were from 2 randomized control trials that compared MCGP (n = 124) to supportive group psychotherapy (n = 94). Mediation effects of treatment status on outcomes (2 months after completion of treatment) via patients' change in sense of meaning and peace (posttreatment minus pretreatment) were tested. The outcome variables used in these analyses were quality of life, depression, hopelessness, and desire for hastened death.

RESULTS

Significant mediation effects via change in sense of meaning and peace on these outcomes were found. Consistent results were found using intention-to-treated statuses. Weaker, but still significant, mediation effects via change in sense of faith on these outcomes were also found.

CONCLUSIONS

Results supported the hypotheses that improvement due to MCGP is mediated by advanced cancer patients' enhanced sense of meaning. These findings highlight the importance of interventions focused on enhancing sense of meaning, as this appears to be a viable route to improve quality of life and decrease psychological distress among patients with advanced cancer.

Home-based multidimensional survivorship programmes for breast cancer survivors

BACKGROUND

The prognosis and survival rate of women with breast cancer have significantly improved worldwide. Effective home-based multidimensional programmes for breast cancer survivors have gained an ever greater emphasis in survivorship care to maximise women's quality of life for their successful transition to rehabilitation and normal life. It is important to summarise the best available evidence to evaluate the effects of home-based multidimensional survivorship programmes on quality of life in women within 10 years of the completion of surgery or adjuvant cancer therapy for breast cancer, or both.

OBJECTIVES

To assess the effects of home-based, multidimensional survivorship (HBMS) programmes on maintaining or improving the quality of life in breast cancer survivors.

SEARCH METHODS

In April 2016 we searched the Cochrane Breast Cancer Specialised Register, CENTRAL, PubMed, Embase, CINAHL Plus, PsycINFO, Web of Science, and the World Health Organization's International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov. We also screened reference lists of all identified studies and contacted study authors.

SELECTION CRITERIA

Randomised controlled trials (RCTs) and quasi-RCTs assessing the effects of HBMS programmes in maintaining or improving quality of life in women with stages 0 to 3 breast cancer who completed primary cancer treatment (surgery or adjuvant cancer therapy, or both) up to 10 years earlier. We considered studies where the interventions included more than one of the following listed components: educational (such as information provision and self-management advice), physical (such as exercise training and resistance training) and psychological (such as counselling and cognitive therapies), to constitute a multidimensional programme. Interventions had to be allowed to be carried out at home.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed eligible studies for inclusion, and performed quality assessment and extracted relevant data of the included studies. Quality of life was the primary outcome of the review.

MAIN RESULTS

We included 22 RCTs and four quasi-RCTs on 2272 participants. We categorised the intervention components into four groups: educational and psychological; educational and physical; physical and psychological; and educational, physical and psychological. Most of the studies used usual care (routine medical follow-up services) as the comparator. A few studies used a lower level or different type of intervention (e.g. stress management or exercise) or attention control as the comparator.We used the Functional Assessment of Cancer Therapy-Breast (FACT B), European Organisation for Research and Treatment of Cancer Quality of Life C30 (EORTC C30), Quality of Life (QoL) Breast Cancer, and SF36 questionnaires to assess quality of life. HBMS programmes may increase breast cancer-specific quality of life and global quality of life immediately after the intervention, as measured by FACT-B and EORTC C30 (FACT-B: mean difference (MD) 4.55, 95% confidence interval (CI) 2.33 to 6.78, 7 studies, 764 participants; EORTC: MD 4.38, 95% CI 0.11 to 8.64, 6 studies; 299 participants; moderate-quality evidence). There was no evidence of a difference in quality of life as measured by QoL-Breast Cancer or SF-36 (QoL-Breast Cancer: MD 0.42, 95% CI -0.02 to 0.85, 2 studies, 111 participants, very low-quality evidence; physical composite score SF36: MD 0.55, 95% CI -3.52 to 4.63, 2 studies, 308 participants, low-quality evidence).We observed a similar pattern at one to three months after the intervention: FACT-B (MD 6.10, 95% CI 2.48 to 9.72, 2 studies, 426 participants), EORTC-C30 (MD 6.32, 95% CI 0.61 to 12.04, 2 studies; 172 participants) and QoL-Breast Cancer (MD 0.45, 95% CI -0.19 to 1.09, 1 study, 61 participants). At four to six months and 12 months, there was no evidence of a difference in quality of life between groups (four to six months: EORTC - MD 0.08, 95% CI -7.28 to 7.44, 2 studies; 117 participants; SF-36 - MD -1.05, 95% CI -5.60 to 3.51, 2 studies, 308 participants; 12 months: EORTC - MD 2.04, 95% CI -9.91 to 13.99, 1 study; 57 participants).Functional status was incorporated into the quality of life subscale findings. HBMS programmes may decrease anxiety (MD of Hospital Anxiety and Depression Scale (HADS) -1.01, 95% CI -1.94 to -0.08, 5 studies, 253 participants, low-quality evidence) compared to control immediately after the intervention but the effect did not persist at four to six months. There was no evidence of improvements in depression immediately after HBMS (MD of HADS -1.36, 95% CI -2.94 to 0.22, 4 studies, 213 participants, low-quality evidence) or at follow-up. HBMS programmes may also decrease fatigue (MD -1.11, 95% CI -1.78 to -0.45, 3 studies, 127 participants; low-quality evidence) and insomnia (MD -1.81, 95% CI -3.34 to -0.27, 3 studies, 185 participants, low-quality evidence).None of the included studies reported service needs and utilisation and cost of care, and therefore the effect of HBMS programmes on healthcare utilisation and cost is unknown. Due to the variations in assessment methods of adherence among the eight studies, we could not combine the results for meta-analysis. We synthesised the results narratively, with the reported adherence rates of 58% to 100%.

AUTHORS' CONCLUSIONS

The results of this systematic review and meta-analysis revealed that HBMS programmes in breast cancer survivors appear to have a short-term beneficial effect of improving breast cancer-specific quality of life and global quality of life as measured by FACT-B and EORTC-C30, respectively. In addition, HBMS programmes are associated with a reduction in anxiety, fatigue and insomnia immediately after the intervention. We assessed the quality of evidence across studies as moderate for some outcomes, meaning that we are fairly confident about the results, while we assessed other outcomes as being low-quality, meaning that we are uncertain about the result.

A mobile application of breast cancer e-support program versus routine Care in the treatment of Chinese women with breast cancer undergoing chemotherapy: study protocol for a randomized controlled trial

BACKGROUND

Women with breast cancer undergoing chemotherapy suffer from a number of symptoms and report receiving inadequate support from health care professionals. Innovative and easily accessible interventions are lacking. Breast Cancer e-Support is a mobile Application program (App) that provides patients with individually tailored information and a support group of peers and health care professionals. Breast Cancer e-Support aims to promote women's self-efficacy, social support and symptom management, thus improving their quality of life and psychological well-being.

METHODS

A single-blinded, multi-centre, randomised, 6-month, parallel-group superiority design will be used. Based on Bandura's self-efficacy theory and the social exchange theory, Breast Cancer e-Support has four modules: 1) a Learning forum; 2) a Discussion forum; 3) an Ask-the-Expert forum; and 4) a Personal Stories forum. Women with breast cancer (n = 108) who are commencing chemotherapy will be recruited from two university-affiliated hospitals in China. They will be randomly assigned to either control group that receives routine care or intervention group that receives routine care plus access to Breast Cancer e-Support program during their four cycles of chemotherapy. Self-efficacy, social support, symptom distress, quality of life, and anxiety and depression will be measured at baseline, then one week and 12 weeks post-intervention.

DISCUSSION

This is the first study of its kind in China to evaluate the use of a mobile application intervention with a rigorous research design and theoretical framework. This study will contribute to evidence regarding the effectiveness of a theory-based mobile application to support women with breast cancer undergoing chemotherapy. The results should provide a better understanding of the role of self-efficacy and social support in reducing symptom distress and of the credibility of using a theoretical framework to develop internet-based interventions. The results will provide evidence to support the implementation of an innovative and easily accessible intervention that enhances health outcomes.

Feasibility of an exercise intervention for fatigued breast cancer patients at a community-based cardiac rehabilitation program

Purpose

Exercise is beneficial to quality of life after cancer treatment, yet few cancer survivors meet exercise guidelines. Our study sought to determine the feasibility of an oncology rehabilitation exercise program embedded within a cardiac rehabilitation program.

Methods

Patients who rated their fatigue >4/10 after completion of adjuvant chemotherapy for breast cancer were screened for eligibility and the outcomes were assessed (Piper Fatigue Scale, Functional Assessment of Cancer Therapy-Breast [FACT-B], Edmonton Symptom Assessment System, body composition, stress test, and physical activity measurement [accelerometer]). Participants received individualized exercise prescription. Following the 16-week program, repeat assessment plus patient acceptance and satisfaction survey was completed. The primary end point was the composite of accrual rate >25%, program adherence >80%, and mean compliance with accelerometer use >80%.

Results

Twenty of 24 screened patients consented to the study and completed the baseline assessment. Adherence was 30.3%. Mean accelerometer use was 3.88/7 days (78%). Fatigue at baseline was rated at 4.82/10, and at 3.59 (p = 0.09) after the intervention. Overall well-being (FACT-B) score changed from 92.7 to 98.3 (p = 0.05). There were no significant changes in body composition (except for bone mineral content), aerobic exercise capacity, or activity patterns.

Conclusion

Although the primary outcome was not met, our study indicates that an oncology exercise rehabilitation program can be incorporated into an existing cardiac rehabilitation program. Based on feedback received, we propose that in order to achieve exercise goals, frequent, encouraging, and tailored feedback and group sessions to foster a sense of community may additionally be needed to strengthen adherence to a prescribed exercise program.

Interventions to enhance return-to-work for cancer patients

BACKGROUND

Cancer patients are 1.4 times more likely to be unemployed than healthy people. Therefore it is important to provide cancer patients with programmes to support the return-to-work (RTW) process. This is an update of a Cochrane review first published in 2011.

OBJECTIVES

To evaluate the effectiveness of interventions aimed at enhancing RTW in cancer patients compared to alternative programmes including usual care or no intervention.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL, in the Cochrane Library Issue 3, 2014), MEDLINE (January 1966 to March 2014), EMBASE (January 1947 to March 2014), CINAHL (January 1983 to March, 2014), OSH-ROM and OSH Update (January 1960 to March, 2014), PsycINFO (January 1806 to 25 March 2014), DARE (January 1995 to March, 2014), ClinicalTrials.gov, Trialregister.nl and Controlled-trials.com up to 25 March 2014. We also examined the reference lists of included studies and selected reviews, and contacted authors of relevant studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of the effectiveness of psycho-educational, vocational, physical, medical or multidisciplinary interventions enhancing RTW in cancer patients. The primary outcome was RTW measured as either RTW rate or sick leave duration measured at 12 months' follow-up. The secondary outcome was quality of life.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for inclusion, assessed the risk of bias and extracted data. We pooled study results we judged to be clinically homogeneous in different comparisons reporting risk ratios (RRs) with 95% confidence intervals (CIs). We assessed the overall quality of the evidence for each comparison using the GRADE approach.

MAIN RESULTS

Fifteen RCTs including 1835 cancer patients met the inclusion criteria and because of multiple arms studies we included 19 evaluations. We judged six studies to have a high risk of bias and nine to have a low risk of bias. All included studies were conducted in high income countries and most studies were aimed at breast cancer patients (seven trials) or prostate cancer patients (two trials).Two studies involved psycho-educational interventions including patient education and teaching self-care behaviours. Results indicated low quality evidence of similar RTW rates for psycho-educational interventions compared to care as usual (RR 1.09, 95% CI 0.88 to 1.35, n = 260 patients) and low quality evidence that there is no difference in the effect of psycho-educational interventions compared to care as usual on quality of life (standardised mean difference (SMD) 0.05, 95% CI -0.2 to 0.3, n = 260 patients). We did not find any studies on vocational interventions. In one study breast cancer patients were offered a physical training programme. Low quality evidence suggested that physical training was not more effective than care as usual in improving RTW (RR 1.20, 95% CI 0.32 to 4.54, n = 28 patients) or quality of life (SMD -0.37, 95% CI -0.99 to 0.25, n = 41 patients).Seven RCTs assessed the effects of a medical intervention on RTW. In all studies a less radical or functioning conserving medical intervention was compared with a more radical treatment. We found low quality evidence that less radical, functioning conserving approaches had similar RTW rates as more radical treatments (RR 1.04, 95% CI 0.96 to 1.09, n = 1097 patients) and moderate quality evidence of no differences in quality of life outcomes (SMD 0.10, 95% CI -0.04 to 0.23, n = 1028 patients).Five RCTs involved multidisciplinary interventions in which vocational counselling was combined with patient education, patient counselling, and biofeedback-assisted behavioral training or physical exercises. Moderate quality evidence showed that multidisciplinary interventions involving physical, psycho-educational and vocational components led to higher RTW rates than care as usual (RR 1.11, 95% CI 1.03 to 1.16, n = 450 patients). We found no differences in the effect of multidisciplinary interventions compared to care as usual on quality of life outcomes (SMD 0.03, 95% CI -0.20 to 0.25, n = 316 patients).

AUTHORS' CONCLUSIONS

We found moderate quality evidence that multidisciplinary interventions enhance the RTW of patients with cancer.

Exercise barriers in Korean colorectal cancer patients

BACKGROUND

To identify barriers to exercise in Korean colorectal cancer patients and survivors, and to analyze differences in exercise barriers by age, gender, treatment status, and physical activity level.

MATERIALS AND METHODS

A total of 427 colorectal cancer patients and survivors from different stages and medical status completed a self-administered questionnaire that surveyed their barriers to exercise and exercise participation.

RESULTS

The greatest perceived exercise barriers for the sampled population as a whole were fatigue, low level of physical fitness, and poor health. Those under 60-years old reported lack of time (p=0.008), whereas those over 60 reported low level of physical fitness (p=0.014) as greater exercise barriers than their counterparts. Women reported fatigue as a greater barrier than men (p<0.001). Those who were receiving treatment rated poor health (p=0.0005) and cancer-related factors as greater exercise barriers compared to those who were not receiving treatment. A multivariate model found that other demographic and medical status were not potential factors that may affect exercise participation. Further, for those who were not participating in physical activity, tendency to be physically inactive (p<0.001) and lack of exercise skill (p<0.001) were highly significant barriers, compared to those who were participating in physical activity. Also, for those who were not meeting ACSM guidelines, cancer-related exercise barriers were additionally reported (p<0.001), compared to those who were.

CONCLUSIONS

Our study suggests that fatigue, low level of physical fitness, and poor health are most reported exercise barriers for Korean colorectal cancer survivors and there are differences in exercise barriers by age, sex, treatment status, and physical activity level. Therefore, support for cancer patients should be provided considering these variables to increase exercise participation.

The effect, moderators, and mediators of resistance and aerobic exercise on health-related quality of life in older long-term survivors of prostate cancer

BACKGROUND

The current study examined effects, moderators (for whom), and mediators (working mechanisms) of 12 months of exercise on health-related quality of life (HRQoL) in older long-term survivors of prostate cancer.

METHODS

In total, 100 men aged 71.7 years (standard deviation, 6.4 years) were randomly assigned to 6 months of supervised aerobic and resistance exercise followed by 6 months of a home-based exercise maintenance program (EX group) or printed education material regarding physical activity for 12 months (PA group). Assessments took place at baseline and after 6 and 12 months. Generalized estimating equations were used to study the effects of EX versus PA on HRQoL at 6 and 12 months, adjusting for baseline HRQoL. The authors examined potential sociodemographic and clinical moderators by adding interaction terms, and potential physical and psychological mediators using the product-of-coefficients test.

RESULTS

At 6 months, significant beneficial effects were found for global QoL, physical function, and social function in the EX group compared with the PA group. For physical function, beneficial effects were sustained at 12 months. Moderation analyses demonstrated larger effects of EX versus PA for patients who were married, started exercising sooner after their diagnosis, and previously used bisphosphonates. Changes in lower body functional performance significantly mediated the effect of EX on global QoL, physical function, and social function. No mediating effects on HRQoL were found for aerobic fitness, physical activity, fatigue, distress, or falls self-efficacy.

CONCLUSIONS

Aerobic and resistance exercise appears to have beneficial effects on HRQoL among older, long-term survivors of prostate cancer. Effects were moderated by marital status, time since diagnosis, and use of bisphosphonates, and were mediated by lower body functional performance.

Rehabilitation model program for seriously ill patients

<b>Background</b><br /> Patients receiving cancer treatment start lifestyle changes mostly at the end of the treatment during the rehabilitation period. Most often, the first step is a dietary change and physical exercises built into the daily routine. Patients who do this in groups led by qualified therapists and based on professional counseling can build more effective and more permanent changes into their life.<br /> To develop a complex rehabilitation program which, in the short term, aims to familiarize patients with a lifestyle which harmonizes the physical, mental, spiritual and social spheres of life and, in the long term, to build it into their everyday life in order to ameliorate the physical and mental state and reduce the psychological symptoms and the isolation of patients. The physical component focuses on diet and exercise. The psycho-social-spiritual support focuses on discovering inner sources of strength, developing active coping mechanisms and helping to achieve more open communication.<br /> <br /> <b>Participants and procedure</b><br /> In February and March 2011, 8 patients treated for malignant tumors participated in the model program. The components of the model program were psychotherapy, physiotherapy, cancer consultation, nutrition counseling, creative activities and walking.<br /> <br /> <b>Results</b><br /> During the period of the model program the isolation of the patients decreased and their social support and ability of coping with the illness ameliorated. They reported an ease in anxiety and depression in their everyday activities. According to feedback, their communication with each other, with the staff and with their relatives became more open. Altogether this had advantageous effects on the functioning of the ward and the mood of the staff.<br /> <br /> <b>Conclusions</b><br /> The rehabilitation program confirmed that beside individual psycho-social support, beneficial and economic psycho-social support can be provided for the patients in group form along with the most effective assignment of the resources of the staff.

Models of Cancer Survivorship Care: Overview and Summary of Current Evidence

INTRODUCTION

This article, derived from a Technical Brief prepared for the Agency for Healthcare Research and Quality, presents an overview on current models of care for survivors of adult-onset cancer who have completed active treatment.

METHODS

This article integrates reviewed literature on background, context, research gaps, and future research directions for survivorship care models. We also conducted a systematic literature review of current evidence from studies of survivorship care models.

RESULTS

Our systematic review identified nine empirical studies of survivorship care models, covering multiple models types and illustrating the heterogeneity in this field. The literature review indicated considerable heterogeneity in models of survivorship care, components of models, survivor populations, and target outcomes. Models of survivorship care are highly individualized to the institution or setting where they are provided. "Usual care" is often uncoordinated and highly varied across cancer survivors and within cancer programs. Anticipated shortages in the oncology workforce may require the expanded use of nurse practitioners and physician assistants and shared care with primary care providers to deliver survivorship care to the growing number of survivors. Concerns associated with survivorship care models include payment considerations, adequacy of training, and the potential for lack of coordination and fragmented care.

CONCLUSION

There is substantial variation in survivorship care models. The optimal nature, timing, intensity, format, and outcomes of survivorship care models are uncertain and require further research. Specific research questions need to be addressed by the survivorship community to better understand the advantages and limitations of survivorship models.

The relationships of self-efficacy, physical activity, and paid work to health-related quality of life among patients with chronic obstructive pulmonary disease (COPD)

Purpose

Although chronic obstructive pulmonary disease (COPD) primarily affects the lungs, it is regarded as a systemic disorder associated with comorbidity and physical deterioration, which often results in reduced levels of health-related quality of life (HRQoL). Self-efficacy is an important concept in self-management, which is vital for improving HRQoL in patients with COPD. The purpose of this study was to examine how general self-efficacy, leisure time physical activity, and sociodemographic variables such as employment status are related to the physical and mental health components of HRQoL in patients with COPD.

Patients and methods

In this cross-sectional study, 97 COPD patients (54.6% male, mean age 64.6 years, standard deviation [SD] 9.5) beginning a pulmonary rehabilitation program completed three self-report questionnaires: the short form (SF)-12v2 Health Survey as a measure of HRQoL; the General Self-Efficacy Scale; and a standardized instrument measuring regular leisure time physical activity.

Results

The physical health component median score was 31.3 (interquartile range [IQR] 16.3) and the mental health component median score was 45.9 (IQR 21.5). Two sets of linear regression analyses were performed, one predicting physical health and the other predicting mental health. The first analysis showed that better physical health was directly related to being in paid work (P-value <0.001), but was not significantly related to age, sex, marital status, education, work status, physical activity, or self-efficacy. In the second analysis, better mental health was directly related to living with a partner, being physically active, and having higher self-efficacy (P-value <0.001).

Conclusion

The findings suggest that general self-efficacy has differential relationships to the two dimensions of HRQoL. Our results indicate that general self-efficacy, physical activity, and paid work might be important factors for improving HRQoL of persons with COPD, and should be taken into consideration in pulmonary rehabilitation.

Physical activity and quality of life of cancer survivors: a lack of focus for lifestyle redesign

BACKGROUND

Physical activity is a component of lifestyle activity and one that has been increasingly seen as 'the medicine' to cure chronic diseases, including certain types of cancer. Physical activity has potent impact on mortality but only if it is well incorporated as lifestyle activity may it allow a better outcome of the quality of life of cancer survivors. This paper presents a review on the evidence of physical activity being actively promoted as lifestyle activity amongst cancer survivors, for the last five years.

MATERIALS AND METHODS

Electronic databases were systematically searched for randomized controlled trials incorporated as lifestyle activity through MEDLINE with the associated terms "physical activity or exercise", "quality of life" and "cancer survivor or people with cancer", 'lifestyle' and 'randomised controlled trial'. The period of search was confined to publication within January 2008 till December 2012 and further limits were to full text, peer reviewed, abstract available and English language.

RESULTS

Based on inclusion criteria, 45 articles were retrieved. Of these, 41 were excluded after examining the full paper. Four final articles on randomized controlled trials were studied to determine the effectiveness of PA to improve the quality of life in post treatment cancer survivors and positive associations were found.

CONCLUSIONS

Physical activity is related to better quality of life of cancer survivors. Only one paper had characteristics of lifestyle incorporation for a lifestyle redesign, but none overtly or actively promoting exercise interventions as an essential lifestyle activity. With increasing survivorship, the benefits of physical activity must be aggressively and overtly promoted to optimize its positive impact.

Mediators of the resistance and aerobic exercise intervention effect on physical and general health in men undergoing androgen deprivation therapy for prostate cancer

BACKGROUND

The objective of the current study was to identify mediators of the effects of a combined resistance and aerobic exercise program on perceived physical and general health in men undergoing androgen deprivation therapy for prostate cancer.

METHODS

In total, 57 patients with prostate cancer undergoing androgen deprivation therapy were randomly assigned to 12 weeks of resistance and aerobic exercise or usual care. The outcome measures of physical and general health were assessed by standardized questionnaires. Linear regression analyses were conducted on the residual change scores of the variables. The mediating effects of fatigue, muscle strength, and functional performance on the intervention's effect on physical and general health were examined using the product of coefficients method. Bootstrapping was used to calculate the 95% confidence intervals (95% CIs).

RESULTS

The exercise intervention was found to significantly improve physical (beta, 5.03; 95% CI, 1.01-9.04) and general health (beta, 12.89; 95% CI, 2.24-23.54). Upper body muscle strength and walking speed significantly mediated the intervention effect on physical health (beta, 2.65; 95% CI, 0.64-5.54), accounting for 53% of the total effect. Walking speed and fatigue were found to be mediators in the intervention effect on general health (beta, 7.52; 95% CI, 2.16-16.92), accounting for 51% of the total effect.

CONCLUSIONS

The intervention effects on physical and general health were explained by different mediating mechanisms. Walking speed mediated the intervention effect on both physical and general health. The intervention effect on physical health was further mediated by upper body strength, whereas the effect on general health was mediated by fatigue.

Evidence-based physical activity guidelines for cancer survivors: current guidelines, knowledge gaps and future research directions

Physical activity during and after cancer treatment has beneficial effects on a number of physical and psychosocial outcomes. This paper aims to discuss the existing physical activity guidelines for cancer survivors and to describe future research directions to optimize prescriptions. Studies on physical activity during and after cancer treatment were searched in PubMed, Clinicaltrials.gov, Australian New Zealand Clinical Trials Registry, and Dutch Trial registry. Physical activity guidelines for cancer survivors suggest that physical activity should be an integral and continuous part of care for all cancer survivors. However, the development of these guidelines has been limited by the research conducted. To be able to develop more specific guidelines, future studies should focus on identifying clinical, personal, physical, psychosocial, and intervention moderators explaining 'for whom' or 'under what circumstances' interventions work. Further, more insight into the working mechanisms of exercise interventions on health outcomes in cancer survivors is needed to improve the efficacy and efficiency of interventions. Finally, existing programs should embrace interests and preferences of patients to facilitate optimal uptake of interventions. In conclusion, current physical activity guidelines for cancer survivors are generic, and research is needed to develop more personalized physical activity guidelines.

Social support and physical activity engagement by cancer survivors

Less than 20% of adult cancer survivors participate in physical activity and, as a result of such inactivity, cancer survivors are at increased risk for developing chronic diseases. Studies have linked social support as a predictor of physical activity participation in healthy adults. The primary goal of this systematic review is to examine the relationship between social support and physical activity engagement in adult cancer survivors and determine whether additional research is needed in this area. Several databases were searched and articles were systematically extracted according to the inclusion and exclusion criteria. That search yielded 69 articles, 22 of which were identified and included in this review. Fifty percent of the studies showed a significant relationship between social support and physical activity engagement; however, 59% of the participants were breast cancer survivors. The findings suggest that additional research is needed to develop social support strategies that will increase physical activity engagement in adult survivors of cancers other than breast cancer.

Effectiveness of multidimensional cancer survivor rehabilitation and cost-effectiveness of cancer rehabilitation in general: a systematic review

INTRODUCTION

Many cancer survivors suffer from a combination of disease- and treatment-related morbidities and complaints after primary treatment. There is a growing evidence base for the effectiveness of monodimensional rehabilitation interventions; in practice, however, patients often participate in multidimensional programs. This study systematically reviews evidence regarding effectiveness of multidimensional rehabilitation programs for cancer survivors and cost-effectiveness of cancer rehabilitation in general.

METHODS

The published literature was systematically reviewed. Data were extracted using standardized forms and were summarized narratively.

RESULTS

Sixteen effectiveness and six cost-effectiveness studies were included. Multidimensional rehabilitation programs were found to be effective, but not more effective than monodimensional interventions, and not on all outcome measures. Effect sizes for quality of life were in the range of -0.12 (95% confidence interval [CI], -0.45-0.20) to 0.98 (95% CI, 0.69-1.29). Incremental cost-effectiveness ratios ranged from -€16,976, indicating cost savings, to €11,057 per quality-adjusted life year.

CONCLUSIONS

The evidence for multidimensional interventions and the economic impact of rehabilitation studies is scarce and dominated by breast cancer studies. Studies published so far report statistically significant benefits for multidimensional interventions over usual care, most notably for the outcomes fatigue and physical functioning. An additional benefit of multidimensional over monodimensional rehabilitation was not found, but this was also sparsely reported on. Available economic evaluations assessed very different rehabilitation interventions. Yet, despite low comparability, all showed favorable cost-effectiveness ratios. Future studies should focus their designs on the comparative effectiveness and cost-effectiveness of multidimensional programs.

Psychosocial predictors of adherence to lymphedema risk minimization guidelines among women with breast cancer

BACKGROUND

The effective management of lymphedema risk following breast cancer surgery and treatment requires enactment of simple behavioural strategies, including regularly checking for early lymphedema symptoms. Adopting a broad self-regulatory perspective, our aim for this study was to identify psychological factors associated with adherence to these risk management strategies.

METHODS

Women (N = 98) recently diagnosed with breast cancer and scheduled for breast and lymph node surgery completed questionnaires prior to surgery and at 3 months post-surgery. Variables assessed included demographics, cognitive belief variables in relation to lymphedema and its management (perceived negative consequences, perceived lymphedema controllability, self-efficacy, perceived personal risk, perceived self-regulatory ability to manage risk-related distress), lymphedema knowledge, trait anxiety and adherence to lymphedema risk management recommendations.

RESULTS

Greater adherence was associated bivariately with greater beliefs in lymphedema controllability, self-efficacy, perceived consequences and perceived self-regulatory ability. Linear regression analyses revealed that only greater beliefs in the controllability of lymphedema and self-regulatory ability, as well as greater knowledge, were predictive of greater adherence to risk management strategies.

CONCLUSIONS

This study highlights the importance of underlying beliefs as determinants of whether a woman who is informed and knowledgeable about lymphedema risk and its management will undertake the recommended risk management actions. Along with raising awareness of lymphedema and its risk management, health professionals should promote positive beliefs among women regarding the controllability of lymphedema through early-detection/early-treatment approaches. In addition, educational approaches should aim to enhance a woman's beliefs in her ability to adhere to these risk management recommendations over time.

Providing Hope in Terminal Cancer: When is it Appropriate and When is it Not?

Hope is essential in the face of terminal cancer. Generally in Western societies, patients and their families prefer their doctor to engage them in transparent, realistic, authoritative, empathic and open communication about the diagnosis and prognosis of cancer but this topic is not well studied in the Asian context. With the exponential increase in information about cancer and the many permutations in cancer treatment, rational and otherwise, the doctor-patient relationship is even more critical in planning the best treatment strategy and also in rendering both particular and general hope in the patient’s war against cancer. Overall, the majority of drugs tested against cancer have failed to reach the market, and those that have, only provide modest benefits, several major therapeutic breakthroughs notwithstanding. Commoditised medicalisation of the dying process ingrained into the contemporary consciousness can potentially create unrealistic or false hope, therapeutic nihilism and a drain on the resources of both the patient and society. These factors can also detract from the dignity of dying as an acceptable natural process. Hope cannot be confined only to focusing merely on the existential dimension of improving survival through technological intervention. Psychosocial and, where appropriate, spiritual interventions and support also play major roles in relieving suffering and providing hope to the patient. Hope cannot be a victim of misinformation from self-interested external parties, nor be an obsession with just buying promises of extending survival time without sufficient regard for quality of life and achieving a good death. Key words: Communicating prognosis, Dying well, Therapeutic nihilism
