Physical activity participation and barriers for people with multiple myeloma

Physical activity and supportive care intervention preferences: a cross-sectional study of barriers in advanced cancer

PURPOSE

Physical activity may greatly benefit adults living with advanced cancer; however, barriers to physical activity and preferences for supportive care interventions are not well understood. This study investigates barriers to physical activity and differences in intervention preferences by demographic and clinical characteristics among adults with advanced cancer.

METHODS

Data came from a cross-sectional study of 247 adults with advanced cancer who visited the University of Wisconsin Carbone Cancer Centre from January 2021 to January 2023. The Godin-Shepard Leisure Score Index (insufficiently active, moderately active and active) was used to assess physical activity. Physical activity barriers were reported as mean scores (1-5: 'not at all' to 'a great deal'). Differences in intervention preferences were assessed using X2 tests.

RESULTS

Adults living with advanced cancer were insufficiently active (53%), moderately active (21%) or active (26%). Respondents identified several barriers to physical activity spanning tiredness (x̄=3.2), winter weather concerns (x̄=3.2) and lack of motivation (x̄=2.7). Respondents were most interested in a supportive care intervention designed to increase energy (88%) and improve physical health (86%) with physical therapy (73%), walking (72%) and resistance exercises (72%). Differences in preferences emerged by demographic characteristics and to a lesser extent by clinical characteristics.

CONCLUSIONS

Adults with advanced cancer reported several barriers to physical activity. Future interventions should emphasise increasing energy and physical health and include strategies to manage tiredness and winter weather concerns.

Decreased Physical Activity and Endurance Capacity in Patients Qualified for Haematopoietic Stem Cell Transplantation (HSCT)

Background: Haematological malignancies and their treatment regimens often lead to various complications that impair patients' physical functioning. This study aimed to assess the level of physical activity and exercise capacity in patients with haematological malignancies who were qualified for haematopoietic stem cell transplantation (HSCT). Methods: A prospective, single-centre study was conducted on patients with haematological malignancies qualified for HSCT (study group, n = 103) and a cohort of healthy volunteers (reference group, n = 100). The assessment protocol included the International Physical Activity Questionnaire (IPAQ) and the 6-Minute Walk Test (6MWT). Results: The median age was 57 years in the study group and 56 years in the reference group. In the IPAQ assessment, at least 50% of the study group reported no engagement in moderate or intense physical activity. In the 6MWT, the study group demonstrated a significantly shorter walking distance compared to the reference group (p < 0.0001). Factors such as group membership (study vs. reference group), age, gender, and body mass index (BMI) were found to have a significant impact on 6MWT performance. No significant differences were observed in IPAQ or 6MWT results among subgroups within the study group when categorized by diagnosis. Conclusions: Patients with haematological malignancies who qualified for HSCT often show physical activity levels below recommended standards, which can negatively impact their ability to endure physical exertion. Insufficient activity prior to transplantation may contribute to reduced exercise capacity. Therefore, prehabilitation programmes aimed at improving physical activity and structured exercise should be an integral part of their care.

Physical activity and exercise motivation of multiple myeloma patients: a prospective cross-sectional study

BACKGROUND

Multiple myeloma (MM) is the second most common hematological malignancy with its prevalence increasing. Patients with symptomatic MM can show numerous comorbidities, affecting their quality of life (QoL). Physical activity (PA) may improve QoL but is not a standardized intervention of comprehensive cancer centers (CCCs). Since data on the PA of patients with MM are scarce, we aimed to prospectively assess fitness levels and patients' motivation to join PA-interventions at our CCC.

METHODS

We generated an exercise questionnaire to interview consecutive patients MM. We prospectively collected data on (a) past and current PA, defined by the World Health Organization (WHO) recommendations, (b) knowledge on exercise effects, (c) exercise motivation, and (d) willingness to participate in PA-interventions. Demographics, comorbidities, response, progression-free survival (PFS), and overall survival (OS) were assessed in 211 symptomatic patients MM.

RESULTS

While our patients were elderly and most showed bone involvement, their PA was similar to healthy individuals. Aerobic PA (≥ 60 minutes/week) was performed by 65%, and 25% exercised ≥ 150 minutes/week. WHO PA recommendations were fulfilled by 17% of patients. No sport activities or complete physical inactivity were observed in 35% and 16%, respectively. Notably, 38% were motivated to join MM-specific sport interventions. Self-reported knowledge of PA-induced benefits for patients cancer was high (82%), but only 27% knew which exercises were safe to perform.

CONCLUSION

This study provides an overview of the PA of patients MM. Our results suggest that the PA of patients MM might not be much lower than in the age-matched general population.

Exercise Preferences, Barriers, and Facilitators of Individuals With Cancer Undergoing Chemotherapy Before Stem Cell Transplantation: A Mixed-Methods Study

BACKGROUND

Exercise can help mitigate side effects of hematopoietic stem cell transplantation (HSCT), particularly when initiated before HSCT. However, the exercise-related barriers, facilitators, and preferences of this population remain unclear.

OBJECTIVE

This study aimed to explore the patient experience to inform future implementation of a prehabilitation intervention.

INTERVENTIONS/METHODS

A 2-phase sequential explanatory mixed-methods study was conducted using (1) cross-sectional survey and (2) focus groups. Survey questions aligned with the Theoretical Domains Framework. Focus group data were analyzed using a directed content analysis approach, followed by inductive thematic analysis to generate themes that represented the exercise-related barriers, facilitators, and preferences of participants.

RESULTS

Twenty-six participants completed phase 1 (n = 22 with multiple myeloma). Fifty percent of participants (n = 13) were fairly/very confident in their ability to exercise pre-HSCT. Eleven participants completed phase 2. Exercise barriers included knowledge/skill limitations, inadequate healthcare provider support, and the emotional toll of treatment. Facilitators included social support and goals. Exercise preferences were related to 2 themes: (1) program structure (subthemes: prescription and scheduling, mode of delivery) and (2) support (subthemes: support from personnel, tailoring, and education).

CONCLUSION

Key exercise-related barriers included knowledge limitations, disease/treatment effects, and inadequate support. Prehabilitation should be tailored, flexible, and include education and a virtual or hybrid delivery model in this population.

IMPLICATIONS FOR PRACTICE

Nurses are well positioned to identify functional limitations and counsel and refer patients to exercise programming and/or physiotherapy services. Including an exercise professional in the pretransplant care team would provide key supportive care assistance for the nursing team.

A multidisciplinary group-based survivorship intervention for those living with multiple myeloma: a feasibility study

BACKGROUND

While multiple myeloma continues to be an incurable cancer, advances in its understanding and management have led to significantly improved survival rates. Survivorship interventions for those living with multiple myeloma remain scarce, despite mounting evidence for multiple unmet support needs among multiple myeloma survivors. The current study aimed to evaluate the feasibility and preliminary effectiveness of a novel multidisciplinary group-based multiple myeloma survivorship intervention.

METHODS

A mixed-method, repeated measures feasibility study was conducted within a routine cancer support service. Seven participants, aged over 18, who had a multiple myeloma diagnosis and were clinically assessed as suitable for the intervention by their haemato-oncologist, attended online for six weekly group sessions of physical exercise and self-management input, completing qualitative, physical and self-report measures at baseline, post-intervention and follow-up.

RESULTS

The intervention was deemed overall feasible, with relatively high uptake, participants describing it as largely acceptable and appropriate and providing recommendations for feasibility-enhancing intervention refinements. Findings regarding the preliminary effectiveness of the intervention were mixed. While qualitative analyses stressed the benefits of the intervention (e.g. peer support, connectedness, improved well-being) and large effect sizes were observed for most physical outcomes, no improvements in self-reported outcomes (i.e. quality of life, fatigue) were reported.

CONCLUSIONS

This study represents the first investigation of a promising novel survivorship intervention for those living with multiple myeloma, highlighting the importance of peer support in particular, on which future clinical trials, aiming to establish the intervention's effectiveness for routine care, will be able to build.

A precision-based exercise program for patients with multiple myeloma

OBJECTIVES

Aim of this study was to retrospectively evaluate an interdisciplinary consultation followed by a precision-based exercise program (PEP) for myeloma patients with stable and unstable bone lesions.

METHODS

Data of myeloma patients (n = 100) who received a PEP according to an orthopedic evaluation were analyzed. Bone stability was assessed by established scoring systems (Spinal Instability Neoplastic Score [SINS], Mirels' score). All patients with stable and unstable osteolyses received a PEP and n = 91 were contacted for a follow-up interview.

RESULTS

In 60% of patients at least one osteolysis of the spine was considered potentially unstable or unstable. Following consultation, the number of patients performing resistance training could be significantly increased (≥2 sessions/week, 55%). Musculoskeletal pain was reported frequently. At the follow-up interview, 75% of patients who performed PEP stated that painful symptoms could be effectively alleviated by exercise. Moreover, only patients who exercised regularly discontinued pain medication. No injuries were reported in association with PEP.

CONCLUSION

We were able to demonstrate that individualized resistance training is implementable and safe for myeloma patients. By means of a PEP, patients' self-efficacy in managing musculoskeletal pain was enhanced and pain medication could be reduced.

Physical activity-related health competence and symptom burden for exercise prescription in patients with multiple myeloma: a latent profile analysis

The purpose of this study is to ensure best possible supply of exercise therapy to patients with multiple myeloma (MM); it is helpful to identify patient groups with similar symptom burden and physical activity-related health competences (PAHCO). Latent profile analyses (LPA) of MM patients were used to identify profiles of patients with similar PAHCO and symptom burden. Analysis of variance was applied to investigate group differences in important covariates. N = 98 MM patients (57% male, age 64 ± 9 years) could be assigned to three distinct PAHCO profiles: 46% were patients with high PAHCO, 48% patients with moderate, and 5% were patients with low PAHCO. The mean probability to be assigned to a certain profile was over 99%. The first group showed significant higher physical activity (PA) and lower comorbidities. Regarding symptom burden, three different profiles exist, including group one (32% of patients) with very low symptom burden, profile two (40%) with medium symptom burden, and group three (15%) with very high symptom burden (mean probability ≥ 98%). Patients in profile one had a lower number of treatment lines compared to the other profiles. Patients who were assigned to the high PAHCO profile were more likely to display a milder symptoms profile. In this exploratory analysis, we identified different patient profiles for PAHCO and symptom burden that may be used to individualize exercise recommendations and supervision modalities in MM patients. PAHCO and symptom burden level may be used to stratify MM patients in order to provide more personalized and effective exercise counseling. The profiles require individualized exercise recommendations and different supervision modalities, including educational instructions tailored particularly to every patient's needs, according to their PAHCO and symptom profile. TRIAL REGISTRATION NUMBER: NCT04328038.

Exercise prehabilitation for people with myeloma undergoing autologous stem cell transplantation: results from PERCEPT pilot randomised controlled trial

BACKGROUND

Autologous stem cell transplant (ASCT) is first line treatment for newly diagnosed patients with myeloma but often results in functional deficits and reduced quality of life (QOL). Physically active myeloma patients have better QOL, less fatigue and reduced morbidity. This trial aimed to investigate the feasibility of a physiotherapist-led exercise intervention delivered across the continuum of the myeloma ASCT pathway at a UK centre. Initially designed and delivered as a face-to-face trial, the study protocol was adapted to virtual delivery in response to the COVID-19 pandemic.

MATERIAL AND METHODS

A pilot randomised controlled trial of a partly supervised exercise intervention with incorporated behaviour change techniques delivered before, during and for 3 months following ASCT compared to usual care. Face-to-face delivery of the pre-ASCT supervised intervention was adapted to virtually-supervised group classes via video conferencing. Primary outcomes related to feasibility; recruitment rate, attrition and adherence. Secondary outcomes included patient reported measures of QOL (EORTC C30, FACT-BMT, EQ5D), and fatigue (FACIT-F), measures of functional capacity (six-minute walk test (6MWT), timed sit-to-stand (TSTS), hand grip strength, self-reported and objective physical activity (PA).

RESULTS

Over 11 months 50 participants were enrolled and randomised. Overall, uptake to the study was 46%. The attrition rate was 34%, mainly related to failure to undergo ASCT. Loss of follow-up for other reasons was low. Secondary outcomes demonstrate potential for the benefit of exercise prior to, during and after ASCT with improvements in QOL, fatigue, functional capacity and PA evident on admission for ASCT and 3 months post-ASCT.

DISCUSSION

Results indicate acceptability and feasibility of delivering exercise prehabilitation, in person and virtually within the ASCT pathway in myeloma. The effects of prehabilitation and rehabilitation provision as a component of the ASCT pathway warrants further investigation.

Exploring participant perceptions of a virtually supported home exercise program for people with multiple myeloma using a novel eHealth application: a qualitative study

INTRODUCTION

Supervision, tailoring, and flexibility have been proposed as key program elements for delivering successful exercise programs for people with multiple myeloma (MM). However, no studies to date have evaluated the acceptability of an intervention employing these components. The aim of this study was to determine the acceptability of a virtually supported exercise program and eHealth application for people with MM.

METHODS

A qualitative description approach was used. One-on-one interviews were conducted with participants who completed the exercise program. Content analysis was used to analyze verbatim transcripts from interviews.

RESULTS

Twenty participants were interviewed (64.9 ± 6.7 years of age, n = 12 females). Participants had positive perceptions of the exercise program. Two themes emerged related to strengths/limitations: One Size Does Not Fit All (sub-themes: Supportive & Responsive Programming and Diverse Exercise Opportunities), and App Usability. Supportive and Responsive Programming was a main strength of the program, characterized as programming that was tailored, involved active support, and delivered by appropriate personnel. The inclusion of Diverse Exercise Opportunities was also regarded as a strength, as it accommodated the preferences of all participants. Related to App Usability, participants felt the app was simple and user friendly but had a few less intuitive components.

CONCLUSION

The virtually supported exercise program and eHealth application were acceptable for people with MM. Programs should employ tailoring, active support, and appropriate personnel to bolster acceptability and include both supervised and flexible exercise formats. eHealth apps should be simple to use so technology proficiency is not a barrier to participation.

Perceptions of Older Adults with Hematological Cancer on Diet and Exercise Behavior and Its Role in Navigating Daily Tasks

Diet and exercise are associated with the maintenance of physical function, independence and better health-related quality of life in cancer survivors. Adherence to healthy diet and exercise guidelines, however, remains low. The aim of this study was to explore the perceptions of hematological cancer survivors (HCS, ≥50 years) on the role of diet and exercise in navigating daily tasks using a qualitative descriptive research method. Eligible HCS completed an online survey gathering demographic information including physical functioning, exercise frequency, malnutrition and frailty risk. Following a semi-structured telephone interview, thematic analysis was used. Nine HCS (67 ± 2 years) were included in the final analysis, with 55.5% sufficiently active, three at risk of malnutrition and five of frailty. Three primary themes reflected the survivors' perceptions: (1) beliefs about the impact of diet and exercise on physical and mental wellbeing, (2) the ability to overcome barriers to adhere to healthy diet and exercise behavior, and (3) diet and exercise empowered and gave hope. Participants had a more nuanced understanding of the role of exercise in physical function but lacked insight into the role of a healthy diet. Knowledge, support and instruction were key enablers of diet and exercise behavior, with community connection a unique enabler identified in this group.

Feasibility of a tailored and virtually supported home exercise program for people with multiple myeloma using a novel eHealth application

Introduction

eHealth exercise interventions have the unique ability to leverage the benefits of in-person programming (tailoring and supervision) with the benefits of home programming (flexibility). There may be a role for eHealth-delivered exercise for people with multiple myeloma (MM), as exercise tailoring and supervision are critical for successful outcomes due to the significant impacts/risks of myeloma-related side effects. The purpose of this study was to determine the safety, feasibility, and preliminary efficacy of a 12-week virtually supported eHealth exercise program.

Methods

Participants with MM completed a 12-week virtually supported home exercise program involving virtually supervised group workouts, independent workouts, and aerobic exercise. Tailoring was facilitated by the functionality of HEAL-Me, a novel eHealth app. Participants completed virtual fitness assessments and questionnaires at baseline and week 12.

Results

Twenty-nine participants consented, 26 completed all follow-up testing (90%). Exercise adherence was 90% (group), 83% (independent), and 90% (aerobic). No serious adverse events (grade ≥3) occurred. Significant improvements were found for quality of life and physical fitness. There was a high level of program/app satisfaction: 96% of participants agreed or strongly agreed that the exercise program was beneficial, 93% found it enjoyable, 89% were satisfied or very satisfied with delivery through the HEAL-Me app, and 48% felt that the eHealth program helped them manage cancer-related symptoms and side-effects.

Conclusion

An eHealth intervention that is individually tailored and includes virtual supervision and active support from the healthcare team is feasible and acceptable to people with MM. The findings from this study warrant investigation using a large-scale randomized controlled trial.

Lifestyle considerations in multiple myeloma

As the prognosis for multiple myeloma (MM) has significantly improved and patients remain on therapy longer, there is a need for supportive care interventions to optimize patient quality of life (QOL) and functional status over the course of cancer treatment. MM is characterized by a significant symptom burden and a relatively lower QOL compared to other cancers. This review evaluates the role of healthy lifestyle behaviors in improving both the physical functioning and psychological well-being of the MM population. We (1) describe the current literature on physical activity, weight management, diet, sleep, and substance use in the context of MM, (2) present important considerations for incorporating lifestyle factors into clinical practice, and (3) identify directions for future research. Developing MM-specific guidelines for modifiable lifestyle changes that take into account both the length of treatment and the unique disease features (i.e. osteolytic lesions and anemia) may provide a promising path for improved patient QOL and functioning.

The effect of exercise-based interventions on health-related quality of life and physical function in older patients with cancer receiving medical antineoplastic treatments: a systematic review

Older patients with cancer are underrepresented in trials investigating the effect of exercise therapy. The aim of this systematic review was to investigate the effect of exercise therapy during medical antineoplastic treatment in older patients (≥ 65 years) with cancer. A systematic review following the Cochrane guidelines was performed. Randomized controlled trials were identified through a systematic literature search in MEDLINE, EMBASE, CENTRAL, and CINAHL up to December 2019. Study selection was performed independently by two reviewers. Four randomized controlled trials published between 2014 and 2019 were included comprising a total of 412 participants. Most participants were diagnosed with breast, prostate or colorectal cancer. The studies were characterized by large differences in design, interventions and outcomes, which prevented meta-analyses. The interventions ranged from 4 weeks to 12 months and involved both supervised and unsupervised exercise programs. Some evidence of beneficial effects from the interventions were documented on physical function, muscle strength, physical activity and cognitive function. No evidence of effects was found for health-related quality of life, aerobic capacity, body composition, cancer-related symptoms and side effects, or for any clinical outcomes. No adverse events were reported. Exercise therapy seems to be safe and feasible in older patients with cancer. However, due to a limited number of studies, small sample sizes and heterogeneity across study design, the effects of exercise in older patients with cancer receiving medical antineoplastic treatment are inconclusive.

Physical Activity in People with Multiple Myeloma: Associated Factors and Exercise Program Preferences

People with multiple myeloma (MM) often experience disease symptoms and treatment toxicities that can be alleviated through physical activity (PA). However, the majority of people with MM are insufficiently active. This study explored PA among people with MM, including differences by treatment stage, symptoms and demographics, and programming preferences. Overall, 126 people with MM (77% response rate) completed the survey. Pre-diagnosis, 25.4% were sufficiently active, with 12.0% remaining active after treatment. Respondents who were physically active pre-diagnosis were 46.7 times (95% confidence intervals CI: 2.03, 1072.1) more likely to meet PA guidelines following an MM diagnosis compared to people not meeting guidelines pre-diagnosis. Experiencing MM symptoms and receiving PA advice from healthcare professionals were not associated with meeting PA guidelines. People with MM were interested in exercise programs (55%) that are low-cost (77%), offered at flexible times (74%), and at locations close to home (69%), both during active treatment and remission (57%), and supervised by an exercise oncology specialist (48%). People with MM, particularly those insufficiently active prior to diagnosis, should be offered convenient, low-cost exercise programs supervised by an exercise oncology specialist to increase PA participation.

Barriers to physical activity in patients with pulmonary hypertension

Patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) have low levels of physical activity (PA). Increased PA has health benefits including improved quality of life. This study aimed to identify patient-perceived barriers to PA that correlate with objectively measured PA in this population. We performed a cross-sectional survey of 40 patients with PAH and CTEPH. Participants rated how often 15 barriers interfere with being physically active on a 5-point Likert Scale. The primary outcome measure was PA quantified using the Fitbit Zip activity tracker for two weeks. The primary independent variables were the 15 barriers and a summary score (total average barriers). Separate multivariable linear regressions were performed to assess the association between the 15 barriers and the summary score and PA adjusting for age, sex, and PAH etiology. Of the participants, 85% (34/40) had valid step counts and were included. Of these 34, 85% (n = 29) were female and 91% (n = 31) had PAH. The median (interquartile range [IQR]) number of daily steps was 3913 (2309-6313). The barriers endorsed most strongly were lack of self-discipline, lack of energy, and lack of interest. In the multivariable analysis, a 1-unit increase in perceived lack of interest, lack of enjoyment, and lack of skills was associated with a significant decrease in step counts of -1414 steps (95% confidence interval [CI] = (-2580 - -248), -1458 steps (-2404 - -511), and -1533 steps (-2910 - -156), respectively. Counseling and interventions aimed at increasing PA in patients with PAH should address interest, enjoyment, and skill development.

Effect of an Inpatient Rehabilitation Program for Recovery of Deconditioning in Hematologic Cancer Patients After Chemotherapy

OBJECTIVE

To investigate the effect of a rehabilitation program in terms of De Morton Mobility Index (DEMMI) score, in hematologic cancer patients after chemotherapy.

METHODS

Hematologic cancer patients admitted for chemotherapy were reviewed. They received a rehabilitation program during their hospital stay. DEMMI score measurement was performed, before and after rehabilitation. Demographics, diagnosis, chemotherapy information, rehabilitation program duration, mortality, body mass index (BMI), and laboratory test results were collected. For analysis, patients were classified according to diagnosis (multiple myeloma, leukemia, and others), mortality, and additional chemotherapy.

RESULTS

There was statistically significant improvement in DEMMI score of 10.1 points (95% confidence interval, 5.9-14.3) after rehabilitation. It was more evident in the multiple myeloma group, and they revealed less mortality. When patients were divided according to mortality, survivors received the program earlier, and in a shorter period than in mortality cases. Although survivors revealed higher initial DEMMI score, improvement after rehabilitation did not differ significantly.

CONCLUSION

In hematologic cancer patients, rehabilitation program was effective for recovery from deconditioning, revealing significant increase in DEMMI score. Multiple myeloma patients may be good candidates for rehabilitation. Rehabilitation could be sustained during chemotherapy and for high-risk patients.

Physical Activity as a Nonpharmacological Symptom Management Approach in Myeloproliferative Neoplasms: Recommendations for Future Research

PURPOSE

Essential thrombocythemia, polycythemia vera, and myelofibrosis are rare chronic hematological malignancies known as myeloproliferative neoplasms (MPNs) and are characterized by deregulated myeloid lineage cell production, splenomegaly, and heterogeneous symptom profiles. MPN patients suffer from a significant symptom burden (eg, fatigue, depressive symptoms, early satiety) and an impaired overall quality of life (QoL). Current treatments typically include pharmacological approaches, which may come with additional side effects and may be limited by treatment-associated toxicities (ie, cytopenias). Nonpharmacological approaches such as physical activity may be beneficial for reducing symptom burden and improving QoL. To date, no studies have examined physical activity as a nonpharmacological approach in MPN patients despite preliminary evidence supporting its benefit in other hematological cancers. The purpose of this article is to (1) review the literature related to physical activity and specific hematological cancer subtypes and to (2) make suggestions for future research involving physical activity in MPN patients as a symptom management strategy.

METHODS

A brief review of studies examining physical activity in leukemias, lymphomas, and myelomas (excluding stem-cell transplant patients) was conducted.

RESULTS

There is preliminary evidence to suggest that physical activity may be an effective approach to improve patient-reported outcomes (fatigue, depression, anxiety, sleep), physical fitness (cardiovascular fitness, balance, body composition), and overall QoL in other hematological cancers.

CONCLUSIONS

Based on encouraging findings in other hematological cancers, future research should examine the feasibility and effectiveness of physical activity in MPN patients.

Multiple myeloma and physical activity: a scoping review

OBJECTIVES

Multiple myeloma is the second most common haematological cancer. A growing body of literature is emerging that investigates the role physical activity plays in all stages of multiple myeloma (prevention and survivorship) and to date no attempt has been made to collate and understand this literature. Therefore, this scoping review aims to (1) outline what is already known about physical activity in all stages of multiple myeloma (2) map the literature on physical activity and multiple myeloma and (3) identify future directions for research.

DESIGN

Scoping Review.

DATA SOURCES

Searches were carried out in May 2015. Searchers were conducted in PubMed, Web of Science, SPORTdiscus and MEDLINE.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

To be included studies had to report original data, investigate physical activity per se or physical activity correlates and multiple myeloma or smouldering multiple myeloma.

RESULTS

A total of 19 papers received full screening, 5 of these papers were excluded. This review identified three journal articles relating to the role of physical activity in the prevention of multiple myeloma, nine papers were identified in the treatment of multiple myeloma and two on smouldering multiple myeloma.

CONCLUSIONS

The search identified that the literature surrounding multiple myeloma and physical activity is very limited. We encourage those designing new cohort studies to allow for future assessment of associations between physical activity and onset of multiple myeloma and smouldering multiple myeloma, as well as the potential role that physical activity plays in the progression from smouldering multiple myeloma to multiple myeloma. Second, we encourage the design and investigation of gender and treatment-specific physical activity interventions in patients with multiple myeloma. Finally, we highlight the need for more randomised controlled trials to evaluate the impact of different types, frequencies and intensities of physical activity on various health parameters in multiple myeloma survivors.

Why do patients choose (not) to participate in an exercise trial during adjuvant chemotherapy for breast cancer?

OBJECTIVE

Only between 25% and 50% of patients invited to participate in clinical trial-based physical exercise programs during cancer treatment agree to do so. The purpose of this study was to identify factors associated significantly with the decision (not) to participate in a randomized controlled trial of physical exercise during adjuvant chemotherapy for breast cancer.

METHODS

Based on questionnaire data, we compared trial participants and non-participants on a range of sociodemographic, clinical health-related, practical, behavioral, and attitudinal variables.

RESULTS

Two hundred thirty of 524 patients agreed to participate in the trial (44%). The 294 (56%) non-participants indicated that they wanted to exercise on their own or that they did not wish to exercise in the context of a trial. Those who preferred to exercise on their own were relatively similar to trial participants but were more likely to be in the maintenance exercise stage. Those non-participants who did not wish to exercise had a significantly lower level of education, were less likely to be working, reported more fatigue and lower health-related quality of life, had lower sense of self-efficacy, more negative attitudes towards exercise, less social support, and perceived fewer benefits and more barriers to exercising during treatment than trial participants.

CONCLUSION

Minimizing practical barriers to participation, providing educational materials on the potential benefits of exercise, and giving adequate professional and social network encouragement may increase the number of patients willing to exercise during treatment and to participate in such studies.

Perceived benefits and barriers to exercise for recently treated patients with multiple myeloma: a qualitative study

BACKGROUND

Understanding the physical activity experiences of patients with multiple myeloma (MM) is essential to inform the development of evidence-based interventions and to quantify the benefits of physical activity. The aim of this study was to gain an in-depth understanding of the physical activity experiences and perceived benefits and barriers to physical activity for patients with MM.

METHODS

This was a qualitative study that used a grounded theory approach. Semi-structured interviews were conducted in Victoria, Australia by telephone from December 2011-February 2012 with patients who had been treated for MM within the preceding 2-12 months. Interviews were transcribed and analysed using the constant comparison coding method to reduce the data to themes. Gender differences and differences between treatment groups were explored.

RESULTS

Twenty-four interviews were completed. The sample comprised 13 females (54%), with a mean age of 62 years (SD = 8.8). Sixteen (67%) participants had received an autologous stem cell transplant (ASCT). All participants currently engaged in a range of light to moderate intensity physical activity; walking and gardening were the most common activities. Recovery from the symptoms of MM and side effects of therapy, psychological benefits, social factors and enjoyment were important benefits of physical activity. Barriers to physical activity predominately related to the symptoms of MM and side effects of therapy, including pain, fatigue, and fear of infection. Low self- motivation was also a barrier. Women participated in a more diverse range of physical activities than men and there were gender differences in preferred type of physical activity. Women were more likely to report psychological and social benefits; whereas men reported physical activity as a way to keep busy and self-motivation was a barrier. Patients treated with an ASCT more often reported affective benefits of participation in physical activity and fatigue as a barrier. Patients treated with other therapies (e.g., chemotherapy, radiotherapy) were more likely to report pain as a barrier.

CONCLUSIONS

Patients with MM experience debilitating effects of their condition and therapy, which influences their level and intensity of physical activity participation. Physical activity programs should be individualised; take into consideration gender differences and the impact of different types of therapy on physical activity; and focus on meeting the psychological, coping and recovery needs of patients.
