RESUMO

PURPOSE: People with advanced or metastatic cancer and their caregivers may have different care goals and face unique challenges compared to those with early-stage disease or those nearing the end-of-life. These MASCC-ASCO standards and practice recommendations seek to establish consistent provision of quality survivorship care for people affected by advanced or metastatic cancer. METHODS: An expert panel comprising MASCC and ASCO members was formed. Standards and recommendations relevant to the provision of quality survivorship care for people affected by advanced or metastatic cancer were developed through conducting: (1) a systematic review of unmet supportive care needs; (2) a scoping review of cancer survivorship, supportive care, and palliative care frameworks and guidelines; and (3) an international modified Delphi consensus process. RESULTS: A systematic review involving 81 studies and a scoping review of 17 guidelines and frameworks informed the initial standards and recommendations. Subsequently, 77 experts (including 8 people with lived experience) across 33 countries (33% were low-to-middle resource countries) participated in the Delphi study and achieved ≥ 94.8% agreement for seven standards (1. Person-Centred Care; 2. Coordinated and Integrated Care; 3. Evidence-Based and Comprehensive Care; 4. Evaluated and Communicated Care; 5. Accessible and Equitable Care; 6. Sustainable and Resourced Care; 7. Research and Data-Driven Care) and ≥ 84.2% agreement across 45 practice recommendations. CONCLUSION: Standards of survivorship care for people affected by advanced or metastatic cancer are provided. These MASCC-ASCO standards will support optimization of health outcomes and care experiences by providing guidance to stakeholders in cancer care (healthcare professionals, leaders, and administrators; governments and health ministries; policymakers; advocacy agencies; cancer survivors and caregivers. Practice recommendations may be used to facilitate future research, practice, policy, and advocacy efforts.

RESUMO

Briefly (10 min) exposing C2C12 myotubes to low amplitude (1.5 mT) pulsed electromagnetic fields (PEMFs) generated a conditioned media (pCM) that was capable of mitigating breast cancer cell growth, migration, and invasiveness in vitro, whereas the conditioned media harvested from unexposed myotubes, representing constitutively released secretome (cCM), was less effective. Administering pCM to breast cancer microtumors engrafted onto the chorioallantoic membrane of chicken eggs reduced tumor volume and vascularity. Blood serum collected from PEMF-exposed or exercised mice allayed breast cancer cell growth, migration, and invasiveness. A secretome preconditioning methodology is presented that accentuates the graded anticancer potencies of both the cCM and pCM harvested from myotubes, demonstrating an adaptive response to pCM administered during early myogenesis that emulated secretome-based exercise adaptations observed in vivo. HTRA1 was shown to be upregulated in pCM and was demonstrated to be necessary and sufficient for the anticancer potency of the pCM; recombinant HTRA1 added to basal media recapitulated the anticancer effects of pCM and antibody-based absorption of HTRA1 from pCM precluded its anticancer effects. Brief and non-invasive PEMF stimulation may represent a method to commandeer the secretome response of muscle, both in vitro and in vivo, for clinical exploitation in breast and other cancers.

RESUMO

People experiencing homelessness find it challenging to access the healthcare they so desperately need. To address this, we have developed the Homeless Health Access to Care Tool, which assesses health related vulnerability (burden of injury and/or illness and ability to access healthcare) and can be used to prioritize people for access to healthcare. Here, we report the initial psychometrics of the Homeless Health Access to Care Tool. To assess interrater reliability, clinician participants were invited to instinctually rate the health-related vulnerability of 18-fictional case studies and then apply the Homeless Health Access to Care Tool to these same case studies. To assess convergent validity, the Homeless Health Access to Care Tool and the tool it was adapted from, the Australian Vulnerability Index Service Prioritization Decision Assistance Tool were administered to people experiencing homelessness. Feedback was sought from the participants receiving these two tools and from those administering them. The Homeless Health Access to Care Tool demonstrated a high interrater reliability and internal consistency. Participants using and receiving the Homeless Health Access to Care Tool reported it as straightforward, unintrusive and clear. Median time of administration was 7 min 29 s (SD 118.03 s). Convergent validity was established for the Homeless Health Access to Care Tool with a moderate correlation (r = 0.567) with the total score of the Australian Vulnerability Index Service Prioritization Decision Assistance Tool. Findings suggest that the Homeless Health Access to Care Tool is feasible and reliable. Larger samples are required to report construct validity.

RESUMO

PURPOSE: Cancer-related fatigue (CRF) is a common and debilitating consequence of cancer and its treatment. Numerous supportive care interventions have been developed to alleviate CRF; however, the diversity of outcome measures used to assess CRF limits comparability of findings. We aimed to evaluate the content and psychometric properties of measures used to assess CRF in interventions targeting fatigue, to inform the selection of suitable measures in future research. METHODS: Included measures were identified from a systematic review of interventions targeting CRF. General characteristics of each measure were extracted, and item content was assessed against domains specified by the National Comprehensive Cancer Network (NCCN) definition of CRF. Psychometric properties were evaluated against COnsensus-based Standards for the selection of heath Measurement INstruments (COSMIN) criteria. RESULTS: Of 54 measures identified, 25 met inclusion criteria. Seventeen were fatigue-specific and eight a fatigue subscale or single item within a broader measure. Only 14 (56%) were specifically developed for cancer populations. Content coverage according to the NCCN CRF definition ranged from 0 to 75%. Evidence for fulfilment of COSMIN criteria in cancer populations ranged from 0 to 93%, with only five measures meeting > 70% of the COSMIN criteria. CONCLUSION: The Piper Fatigue Scale-Revised had good content coverage, but did not comprehensively address COSMIN criteria. The EORTC-FA12 and FACIT/FACT-F had excellent psychometric properties, with each capturing different aspects of fatigue. Ultimately, the choice of CRF measure should be guided by the research question and the CRF domains most relevant to the particular research context.

RESUMO

Examining and addressing unmet care needs is integral to improving the provision and quality of cancer services. This review explored the prevalence of unmet supportive care needs, and factors associated with unmet need, in adults with advanced cancers (solid and hematological malignancies) and their caregivers. Electronic databases (PubMed, CINAHL, EMBASE) were searched, producing 85 papers representing 81 included studies. People with advanced cancer reported the highest unmet needs in financial, health system and information, psychological, and physical and daily living domains, whereas caregivers reported the highest unmet needs in psychological, and patient care and support domains. Distress, depression, and anxiety were associated with higher unmet needs across all unmet need domains for people with advanced cancer and their caregivers. Substantial heterogeneity in study populations and methods was observed. Findings from this review can inform targeted strategies and interventions to address these unmet needs in people with advanced cancer.

RESUMO

PURPOSE: Tumour blood vessels are structurally and functionally abnormal, resulting in areas of hypoxia and heterogeneous blood supply. Aerobic exercise may modulate tumour blood flow and normalise the tumour microenvironment to improve chemotherapy delivery. This systematic review and meta-analysis aimed to evaluate the effect of the aerobic exercise mode on tumour hypoxia, vascularisation and blood flow. METHODS: Four online databases were searched. Preclinical and clinical randomised controlled trials examining the effects of aerobic exercise training on hypoxia, vascularisation or blood flow in solid tumours were included. The risk of bias was assessed and a meta-analysis performed. RESULTS: Seventeen preclinical studies and one clinical study met criteria. Eleven studies assessed hypoxia, 15 studies assessed vascularisation and seven evaluated blood flow. There was large variability in measurement methods, tumour types and exercise program designs. The overall risk of bias was unclear in clinical and preclinical studies, owing to poor reporting. There was no significant effect of aerobic exercise on hypoxia (SMD = -0.17; 95% CI = -0.62, 0.28; I2 = 60%), vascularisation (SMD = 0.07; 95% CI = -0.40, 0.55; I2 = 71%) or blood flow (SMD = 0.01; 95% CI = -0.59, 0.61; I2 = 63%). CONCLUSION: There is heterogeneity in methodology, resulting in evidence that is inconsistent and inconclusive for the effects of aerobic exercise on hypoxia, vascularisation and blood flow. Most evidence of aerobic exercise effects on tumour blood flow is in animal models, with very limited evidence in humans.

RESUMO

Virological failure occurs in a small proportion of people treated for hepatitis C virus (HCV) with direct-acting antiviral (DAA) therapies. This study assessed retreatment for virological failure in a large real-world cohort. REACH-C is an Australian observational study (n=10843) evaluating treatment outcomes of sequential DAA initiations across 33 health services between March 2016 to June 2019. Virological failure retreatment data were collected until October 2020. Of 408 people with virological failure (81% male; median age 53; 38% cirrhosis; 56% genotype 3), 213 (54%) were retreated once; 15 were retreated twice. A range of genotype specific and pangenotypic DAAs were used to retreat virological failure in primary (n=56) and tertiary (n=157) settings. Following sofosbuvir/velpatasvir/voxilaprevir availability in 2019, the proportion retreated in primary care increased from 21% to 40% and median time to retreatment initiation declined from 294 to 152 days. Per-protocol (PP) sustained virological response (SVR12) was similar for people retreated in primary and tertiary settings (80% vs 81%; p=1.000). In regression analysis, sofosbuvir/velpatasvir/voxilaprevir (vs. other regimens) significantly decreased likelihood of second virological failure (PP SVR12 88% vs. 77%; adjusted odds ratio [AOR] 0.29; 95%CI 0.11-0.81); cirrhosis increased likelihood (PP SVR12 69% vs. 91%; AOR 4.26; 95%CI 1.64-11.09). Indigenous Australians had lower likelihood of retreatment initiation (AOR 0.36; 95%CI 0.15-0.81). Treatment setting and prescriber type were not associated with retreatment initiation or outcome. Virological failure can be effectively retreated in primary care. Expanded access to simplified retreatment regimens through decentralised models may increase retreatment uptake and reduce HCV-related mortality.

RESUMO

OBJECTIVES: In this paper, we report the development of the Homeless Health Access to Care Tool. This tool aims to improve the gap in assessing health need and capacity to access healthcare of people experiencing homelessness. Tools exist that prioritise people experiencing homelessness for housing, but none specifically designed to prioritise for healthcare, or that are succinct enough to be easily implemented to emergency department or primary healthcare settings. DESIGN AND SETTING: The Homeless Health Access to Care Tool has been adapted from an existing tool, the Vulnerability Index Service Prioritisation Decision Assistance Tool through a five-step process: (1) domain identification, (2) literature review, (3) analysis of hospital admission data, (4) expert judges, and (5) Delphi study. PARTICIPANTS: The tool was adapted and developed by homeless health clinicians, academics and people with lived experience of homelessness. The Delphi study (n=9) comprised emergency department and homeless health clinicians. RESULTS: Consensus was gained on all but one item, five new items were added, and wording changes were made to six items based on expert feedback. Participants perceived the tool would take between 5 to 11 min to complete, the number of items were appropriate, and the majority agreed it would facilitate the assessment of health needs and capacity to access healthcare. CONCLUSION: Robust development of the Homeless Health Access to Care Tool through the Delphi is the first phase of its development. The Homeless Health Access to Care Tool offers an opportunity to assess both health need and capacity to access healthcare with the aim to improve access to healthcare for people experiencing homelessness. This tool will facilitate standardised data collection to inform service design and data linkage regarding access to healthcare of people experiencing homelessness. The next stages of testing include construct validity, feasibility, usability and inter-rater reliability, and pilot implementation.

RESUMO

Australia was one of the first countries with unrestricted access to government subsidized direct-acting antiviral (DAA) therapy for adults with chronic hepatitis C virus. This study assessed real-world DAA treatment outcomes across a diverse range of Australian clinical services and evaluated factors associated with successful treatment and loss to follow-up. Real-world Effectiveness of Antiviral therapy in Chronic Hepatitis C (REACH-C) consisted a national observational cohort of 96 clinical services including specialist clinics and less traditional settings such as general practice. Data were obtained on consecutive individuals who commenced DAAs from March 2016 to June 2019. Effectiveness was assessed by sustained virological response ≥12 weeks following treatment (SVR) using intention-to-treat (ITT) and per-protocol (PP) analyses. Within REACH-C, 10,843 individuals initiated DAAs (male 69%; ≥50 years 52%; cirrhosis 22%). SVR data were available in 85% (9,174 of 10,843). SVR was 81% (8,750 of 10,843) by ITT and 95% (8,750 of 9,174) by PP. High SVR (≥92%) was observed across all service types and participant characteristics. Male gender (adjusted odds ratio [aOR] 0.56, 95% confidence interval [CI] 0.43-0.72), cirrhosis (aOR 0.52, 95% CI 0.41-0.64), recent injecting drug use (IDU; aOR 0.64, 95% CI 0.46-0.91) and previous DAA treatment (aOR 0.50, 95% CI 0.28-0.90) decreased the likelihood of achieving SVR. Multiple factors modified the likelihood of loss to follow-up including IDU ± opioid agonist therapy (OAT; IDU only: aOR 1.75, 95% CI 1.44-2.11; IDU + OAT: aOR 1.39, 95% CI 1.11-1.74; OAT only, aOR 1.36; 95% CI 1.13-1.68) and age (aOR 0.97, 95% CI 0.97-0.98). Conclusion: Treatment response was high in a diverse population and through a broad range of services following universal access to DAA therapy. Loss to follow-up presents a real-world challenge. Younger people who inject drugs were more likely to disengage from care, requiring innovative strategies to retain them in follow-up.

RESUMO

PURPOSE: Physical activity is a well-established strategy to alleviate breast cancer-related adverse outcomes. To optimise health benefits, behaviour change theories provide frameworks to support women in improving their physical activity. This review aimed to evaluate (i) the effects of behaviour change theory-based physical activity interventions for women with breast cancer and (ii) the application of these theories. METHODS: Seven online databases were searched. Trials were included if randomised and controlled, involved physical activity interventions ≥ 12 weeks duration, used a behaviour change theory, and participants were < 3 years post-cancer treatment. Risk of bias and theory use were assessed. Data were synthesised narratively and meta-analysed. RESULTS: Forty articles describing 19 trials were included. Overall risk of bias was moderately high. Post-intervention pooled effect estimates were medium for self-reported (SMD = 0.57) and objectively measured physical activity (SMD = 0.52). Most trials cited the social cognitive theory (n = 10) and transtheoretical model (n = 9). Trials rarely applied theories in their entirety, expounded on behavioural mechanisms, or tailored interventions according to behavioural constructs. The most commonly used types of behavioural techniques were goals and planning (n = 18), shaping of knowledge (n = 18), feedback and monitoring (n = 17), and comparisons of outcomes (n = 17). CONCLUSIONS: The included trials were effective for increasing physical activity in women with breast cancer. Theories were applied using a wide range of approaches and levels of rigour, although shared the use of common behavioural techniques. IMPLICATIONS FOR CANCER SURVIVORS: Future research may benefit breast cancer survivors by more comprehensively applying behaviour change theories, emphasising individual patient needs and goals.

RESUMO

BACKGROUND: Direct acting antiviral (DAA) therapy is highly effective for hepatitis C virus (HCV) infection, but reinfection following treatment may compromise benefits of cure. This study assessed the real-world effectiveness of treatment for reinfection. METHODS: Real-world effectiveness of antiviral therapy in chronic hepatitis C (REACH-C) is an observational study evaluating treatment outcomes following sequential DAA initiations across 33 health services in Australia between March 2016-June 2019. Reinfection was defined by post-treatment genotype switch or HCV viraemia after sustained virologic response (SVR12). RESULTS: Of the 10,843 individuals initiating DAA therapy post-treatment viraemia was reported in 526 of whom 99 were reinfections. Treatment for reinfection occurred in 88 individuals. In those with available treatment outcomes, SVR12 was similar to initial treatment in the overall REACH-C cohort (95% vs 95%; p = 0.745) and comparable across primary, tertiary, and prison settings. Classifying unknown treatment outcomes as failures, SVR12 for treatment of reinfection was lower than initial treatment in REACH-C (67% vs 81%; p = 0.002), due to higher lost to follow-up. CONCLUSIONS: Treatment of reinfection is highly effective and can be delivered in non-specialist settings. Access to treatment for reinfection in high-risk populations is crucial to HCV elimination.

RESUMO

BACKGROUND: The objectives of this scoping review are to investigate the characteristics assessed by existing vulnerability indices and the health outcomes achieved by applying them to people experiencing homelessness. This review forms part of the development and implementation of a novel tool to prioritise people experiencing homelessness for healthcare based on their need and capacity to access healthcare. METHODS: Included papers were primary research, published in the English language, participants were experiencing homelessness and aged over 18 years at the time of the study, a vulnerability index was used in the study, sample size was greater than 30, and the study had a health focus. Databases searched were MEDLINE, Embase, CINAHL, Scopus, PubMed and Web of Science, between January-April 2020. The Joanna Briggs Appraisal criteria were used to quality appraise the included studies. Results were synthesised narratively. RESULTS: Six papers were included, a total of 27,509 participants. The reported use of the indices varied; they included screening and profiling homeless populations, comparing homeless populations, and two studies evaluated the predictive capacity, reliability and validity of the indices. One vulnerability index focused on screening for human immunodeficiency virus, one used a 50-item index and four used a nine-item index. No direct health outcomes were reported from applying the vulnerability indices. The studies identified limitations of using vulnerability indices, including the potential bias of relying on self-reported data and two studies highlighted the need for further psychometric testing to ensure validity and reliability of the indices. DISCUSSION: The sample of included studies was small. Vulnerability indices are reportedly a useful and easily accessible method of gaining valuable data on the health status and health needs of people experiencing homelessness. The variety of characteristics included in the vulnerability indices suggests the importance of tailoring vulnerability indices to the needs of the population to which it is to be applied. Conducting appropriate psychometric testing is critical so that an index can be used to accurately inform decision making and accurately prioritise people experiencing homelessness who are most at risk of mortality and morbidity. A specific tool that prioritises people experiencing homelessness for access to health care is not yet available. The review was funded by a St Vincent's Network Inclusive Health grant.

RESUMO

OBJECTIVE(S): To evaluate changes in injecting and sexual risk behaviours, and hepatitis C virus (HCV) reinfection incidence among people with HIV/HCV coinfection following unrestricted access to direct-acting antiviral therapy in Australia. DESIGN: Prospective observational cohort study (2014-2018). METHODS: Among people enrolled in the Control and Elimination of HCV from HIV-infected individuals within Australia study, changes in injecting and sexual behaviour were evaluated, including injecting drug use (IDU) in the last 6 months and last month, frequency of IDU and equipment sharing, condom-less anal intercourse with casual male partner(s), and group sex. HCV reinfection incidence was evaluated with follow-up through May 2018. RESULTS: Overall, 272 HIV/HCV antibody-positive participants [median age; 50 years, 96% male, 83% identified as gay and bisexual men (GBM)] had behavioural data at enrolment and follow-up (median 2.91 years) available for analysis. The proportion reporting IDU in the last 6 months remained stable from enrolment (35%) to follow-up (39%). Among GBM, the proportion reporting condom-less anal intercourse with casual partner(s) at enrolment (48%) and follow-up (46%) was also similar. Reinfection was detected in five individuals (all GBM) during total follow-up of 474 person-years for an overall incidence of 1.05 per 100 person-years (95% confidence interval, 0.44-2.53). CONCLUSION: No change was observed in levels of injecting or sexual risk behaviour for HCV infection following unrestricted access to direct-acting antiviral therapy in an Australian HIV/HCV cohort. Incidence of HCV reinfection was low potentially reflecting high levels of treatment coverage within this population. Continued screening and rapid retreatment of reinfection will be required to maintain progress towards elimination.

RESUMO

BACKGROUND: Microelimination of hepatitis C virus (HCV) among people living with human immunodeficiency virus (HIV) may be feasible in Australia, given unrestricted access to direct-acting antiviral (DAA) therapy from 2016. Our aim was to evaluate progress towards elimination goals within HIV/HCV-coinfected adults in Australia following universal DAA access. METHODS: The CEASE prospective cohort study enrolled adults with HIV/HCV, irrespective of viremic status, from 14 primary and tertiary clinics in Australia. Annual and cumulative HCV treatment uptake, outcome, and HCV RNA prevalence were evaluated, with follow-up through May 2018 (median follow-up, 2.63 years). Factors associated with DAA uptake were analyzed. RESULTS: Between July 2014 and March 2017, 402 participants who were HIV/HCV antibody positive were enrolled (95% male [80% gay and bisexual men,], 13% cirrhosis, 80% history of injecting drug use [39% currently injecting]). Following universal DAA access, annual HCV treatment uptake in those eligible increased from 7% and 11% per year in 2014 and 2015, respectively, to 80% in 2016. By 2018, cumulative HCV treatment uptake in those ever eligible for treatment was 91% (336/371). HCV viremic prevalence declined from 82% (95% CI, 78-86%) in 2014 to 8% (95% CI, 6-12%) in 2018. Reinfection was reported in only 5 participants for a reinfection incidence of 0.81 per 100 person-years (95% CI, 0.34-1.94). CONCLUSIONS: High uptake and effectiveness of unrestricted DAA therapy in Australia have permitted rapid treatment scale-up, with a dramatic reduction in HCV infection burden and low reinfection rate among people living with HIV, suggesting that microelimination is feasible.

RESUMO

CONTEXT: Physical activity for women with early-stage breast cancer is well recognized for managing cancer-related symptoms and improving quality of life. While typically excluded from interventions, women with metastatic breast cancer may also benefit from physical activity. OBJECTIVE: To 1) determine the safety and feasibility of a physical activity program for women with metastatic breast cancer and 2) explore the efficacy of the program. METHODS: Fourteen women with metastatic breast cancer were randomized to either a control group or an 8-week home-based physical activity intervention comprising twice weekly supervised resistance training and an unsupervized walking program. RESULTS: The recruitment rate was 93%. Adherence to the resistance and walking components of the program was 100% and 25%, respectively. No adverse events were reported. When mean change scores from baseline to postintervention were compared, trends in favor of the exercise group over the control group were observed for the Functional Assessment of Chronic Illness Therapy-Fatigue score (+5.6 ± 3.2 vs. -1.8 ± 3.9, respectively), VO2max (+1.6 ml/kg/minute ±1.8 mL/kg/minute vs. -0.2 mL/kg/minute ±0.1 mL/kg/minute, respectively) and six-minute walk test (+40 m ± 23 m vs. -46 m ± 56 m, respectively). CONCLUSION: A partially supervised home-based physical activity program for women with metastatic breast cancer is feasible and safe. The dose of the resistance training component was well tolerated and achievable in this population. In contrast, adherence and compliance to the walking program were poor. Preliminary data suggest a physical activity program, comprising predominantly resistance training, may lead to improvements in physical capacity and may help women to live well with their disease.

RESUMO

Metastatic breast cancer is a disease of changing status-once an imminent death sentence, now a chronic (albeit incurable) disease. Medical intervention advances mean women with metastatic breast cancer now have symptoms alleviated and, potentially, life extended. Living with this disease, however, requires more than a medical approach to symptoms. We were interested to know whether women manage, and if so, how, to "live well" with metastatic cancer. We conducted interviews with 18 women. Women differed in the approaches they used. Most common was the attempt to reestablish a sense of normality in their lives. However, a second group reevaluated and reprioritized their lives; and a third group was restricted in their capacity to live well because of symptoms. The findings provide the foundation for future research exploring normalization of experiences of metastatic cancer, and other chronic illnesses, where people are living with knowledge that they have contracted time.

RESUMO

OBJECTIVE: The purpose of this qualitative research was to identify the healthcare, information and support needs of women living with metastatic breast cancer. MATERIALS AND METHODS: Semi-structured qualitative interviews were conducted with 18 women. Women were asked about their experiences of living with metastatic breast cancer and their information and support needs. RESULTS: Women valued relationships with their healthcare professionals, particularly their oncologists. They wanted more attention paid to side-effects of ongoing treatments, which had a negative impact on their health. While oncologists were a primary source of information, women also drew on other sources. There were mixed findings about the value of support groups, with women preferring to seek alternative sources of social support. CONCLUSION: A diagnosis of metastatic breast cancer brings heightened reliance on healthcare professionals to respond to women's needs in a way that is different to that required with a diagnosis of early breast cancer.

RESUMO

PURPOSE: This study aimed to explore differences in physical activity and fitness between women with metastatic breast cancer compared to healthy controls and factors associated with their physical activity levels. METHODS: Seventy-one women with metastatic breast cancer, aged (mean (SD)) 57.7 (9.5) and 2.9 (3.1) years after the onset of metastatic disease, and 71 healthy controls aged 55.0 (9.4) years participated. Of those with metastatic disease, 27% had bone-only metastases, 35% visceral-only metastases and 38% bone and visceral metastases. Patient-reported outcomes and physical measures of muscle strength and aerobic fitness assessments were obtained. Participants wore a SenseWear® physical activity monitor over 7 days, and the average steps/day and the time spent in moderate-to-vigorous intensity physical activity were determined. RESULTS: Women with metastases were significantly (i) less aerobically fit than the control group (25.3 (5.4) vs. 31.9 (6.1) mL • kg(-1) • min(-1); P < 0.001); (ii) weaker (e.g. lower limb strength for the metastatic and control groups was 53.5 (23.7) vs. 76.0 (27.4) kg, respectively; P < 0.001); (iii) less active, with the metastatic group attaining only 56% of the mean daily step counts of the healthy women; and (iv) more symptomatic, reporting higher levels of fatigue and dyspnoea (P < 0.001). CONCLUSION: Women living in the community with metastatic breast cancer possessed lower aerobic fitness, reduced muscular strength and less daily physical activity compared to healthy counterparts. They also experienced poorer functioning and higher symptom burden. IMPLICATIONS FOR CANCER SURVIVORS: Women living with metastatic breast cancer may benefit from a physical activity programme to address their physical impairments.
