Exercise in newly diagnosed patients with multiple myeloma: A randomized controlled trial of effects on physical function, physical activity, lean body mass, bone mineral density, pain, and quality of life

Reduced physical function caused by bone destruction, pain, anemia, infections, and weight loss is common in multiple myeloma (MM). Myeloma bone disease challenges physical exercise. Knowledge on the effects and safety of physical exercise in newly diagnosed patients with MM is limited. In a randomized, controlled trial, we studied the effect of a 10-week individualized physical exercise program on physical function, physical activity, lean body mass (LBM), bone mineral density (BMD), quality of life (QoL), and pain in patients newly diagnosed with MM. Lytic bone disease was assessed, and exercise was adjusted accordingly. Primary outcome: knee extension strength. Secondary outcomes: Six-Minute-Walk-Test, 30-s Sit-to-Stand-Test (SST), grip strength, level of physical activity, LBM, BMD, QoL, and pain. Measurements were conducted pre- and post-intervention, and after 6 and 12 months. We included 100 patients, 86 were evaluable; 44 in the intervention group (IG) and 42 in the control group (CG). No statistically significant differences between groups were observed. Knee extension strength declined in the IG (p = .02). SST, aerobic capacity, and global QoL improved in both groups. Pain decreased consistently in the IG regardless of pain outcome. No significant safety concerns of physical exercise in newly diagnosed patients with MM were observed.

Limited Evidence for the Benefits of Exercise in Older Adults with Hematological Malignancies: A Systematic Review and Meta-Analysis

Older patients receiving antineoplastic treatment face challenges such as frailty and reduced physical capacity and function. This systematic review and meta-analysis aimed to evaluate the effects of exercise interventions on physical function outcomes, health-related quality of life (QoL), and symptom burden in older patients above 65 years with hematological malignancies undergoing antineoplastic treatment. This review adheres to Cochrane guidelines, with the literature searches last updated on 27 March 2024, including studies with patients above 18 years. Screening of identified studies, data extraction, risk of bias, and GRADE assessments were performed independently by two authors. Meta-analyses evaluated the impact of exercise, considering advancing age. Forty-nine studies contributed data to the meta-analyses. Five studies included patients with a mean age above 60 years, and none included only patients above 60. Exercise interventions had moderate to small positive effects on QoL global (SMD 0.34, 95% CI [0.04-0.64]) and physical function (SMD 0.29, 95% CI [0.12-0.45]). Age did not explain the variability in exercise effects, except for physical function (slope 0.0401, 95% CI [0.0118-0.0683]) and pain (slope 0.0472, 95% CI [0.01-0.09]), which favored younger patients. Exercise interventions improve physical function and QoL and reduce symptoms in adults with hematological malignancies undergoing antineoplastic treatment; however, the influence of age remains inconclusive.

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.

Effects on the Physical Functioning of Two Exercise Interventions in Patients with Multiple Myeloma: A Pilot Feasibility Study

Because of the high prevalence of bone destruction in patients with multiple myeloma (MM), physical exercise is oftentimes discouraged by healthcare providers. The goal of this prospective trial was to investigate the feasibility of two six-month exercise interventions in patients with MM (N = 42): a remotely prompted home-based walking intervention or a supervised strength training intervention. Physical function and pain were assessed with the Activity Measure for Post-Acute Care (AM-PAC) Basic Mobility Short Form raw score, a six-minute walk test (6 MWT), a 30-second sit-to-stand test (30 SST), a timed up-and-go (TUG) test, a visual analog scale (VAS) for pain, handheld dynamometer tests, heart rate at rest, blood oxygen saturation at rest, and body mass index. No intervention-related serious adverse events were observed. Adverse events mostly affected the musculoskeletal system. In the resistance training group (n = 24), patients showed significant improvements in AM-PAC, TUG, 6 MWT, and 30 SST, with all effects but the 6 MWT sustained six months after the intervention. The walking group (n = 18) saw improvements in the AM-PAC, TUG, 6 MWT, and 30 SST, with a sustained change in the AM-PAC and TUG. This trial shows the feasibility of both exercise interventions with a sustained beneficial effect on the physical functioning of a six-month strength training intervention and, to a lesser extent, a six-month unsupervised walking intervention. A larger study building on these findings is currently underway.

Effect of non-pharmacological interventions on symptoms and quality of life in patients with hematological malignancies - A systematic review

BACKGROUND

Non-pharmacological interventions have the potential to enhance health-related quality of life (HRQoL) through symptom management. This systematic review aims to identify, collate, and assess randomized controlled trials investigating the effect of non-pharmacological interventions on symptoms and HRQoL within hematology.

METHODS

MEDLINE/PUBMED, EMBASE, CINAHL, PSYCINFO and COCHRANE were searched up to April 2021. Outcomes were changes in symptoms and HRQoL.

RESULTS

Sixty-five studies were categorized into five intervention types: Mind/body (n=9), Web-based (n=9), Music/art (n=6), Consultation-based (n=4), and Physical activity (n=37). We found significantly reduced fatigue (n=12 studies), anxiety (n=8) and depression (n=7), with 11 studies showing significant improvements in HRQoL.

CONCLUSIONS

The evidence for non-pharmacological interventions shows substantial variation in efficacy and methodological quality. While specific symptoms and HRQoL outcomes significantly favored the intervention, no particular intervention can be emphasized as more favorable, given the inability to conduct a meta-analysis.

Effects of resistance training on sleep quality and disorders among individuals diagnosed with cancer: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Sleep disorders are often complained by cancer patients and can last years after the end of therapies, leading to different negative consequences. Non-pharmacological strategies such as exercise interventions may be considered to counteract this phenomenon. The literature supports the beneficial effects of aerobic training (AT), while evidence on resistance training (RT) is scarce. Accordingly, our systematic review aims to investigate the potential novel effect of RT on sleep outcomes in cancer survivors.

METHODS

The literature search was conducted on MEDLINE (Pubmed), Web of Science, Scopus, and Cochrane Central Register of Controlled Trials databases, including only randomized controlled trials (RCTs). The screening procedure was conducted using the web-based software COVIDENCE. Sleep outcomes assessed through self-reported questionnaires or objective sleep measurements were extracted from RCTs recruiting cancer survivors of any age and gender, on or off treatment. The risk of bias (RoB) for each study was assessed using the Cochrane RoB 2 tool for RCTs. Meta-analytic syntheses were performed on sleep quality and insomnia.

RESULTS

A total of 21 studies were included in the review. Considering the mean percentage differences of all studies combined, promising positive results were found after combined aerobic and resistance exercise program (COMB) for sleep quality (-19%) and sleep disturbance (-17.3%). The meta-analysis results showed significant improvement for both sleep quality and insomnia (d = 0.28, SE: 0.11, Z = 2.51, p < 0.01, 95% CI: 0.07-0.49 and d = 0.43, SE: 0.20, Z = 2.18, p = 0.029, 95% CI: 0.07-0.49, respectively).

CONCLUSION

RT interventions of 60 minutes per session, performed 2-3 times a week for 12 weeks, with exercise intensity ranging from 60% to 80% of one-repetition maximum can be administered to cancer survivors, aiming to improve sleep outcomes.

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.

Effects of Exercise Rehabilitation on Physical Function in Adults With Hematological Cancer Receiving Active Treatment: A Systematic Review and Meta-Analysis

OBJECTIVE

Evaluate the efficacy of exercise rehabilitation at improving physical function during active treatment for adults diagnosed with a hematological malignancy.

DATA SOURCE

Systematic review with a multilevel meta-analysis of randomized trails was conducted. Four electronic databases, MEDLINE (EBSCOhost), CINAHL, Scopus, and CENTRAL, were searched using key words and medical subject headings. Articles were screened and assessed against the predetermined eligibility criteria. Data extracted were appraised using the Cochrane risk of bias tool for randomized trials and the GRADE guidelines. A meta-analysis examined four key clinical objectives.

CONCLUSION

Twelve studies representing a total of 812 participants were included. Analysis of 36 dependent effect sizes from nine studies revealed structured and prescribed exercise interventions improved physical function (SMD = 0.39; 95% CI 0.21-0.57) compared to usual care or an active control. Exercise interventions with a multimodal design consisting of both aerobic and resistance exercise had a statistically significant effect on physical function (P < .001). Exercise intensity also had a statistically significant effect on physical function when prescribed at a moderate (P = .003) and vigorous (P < .001) intensity during active treatment in patients with leukemia or lymphoma.

IMPLICATIONS FOR NURSING PRACTICE

This review suggests individuals diagnosed with leukemia or lymphoma can optimize physical function during and immediately post-treatment by attending exercise rehabilitation 3-5 times per weeks performing moderate-vigorous aerobic and resistance exercise. While further research is needed to identify optimal prescription guidelines throughout the treatment continuum, this review underscores the importance for hematology nurses to support patient referrals to exercise oncology professionals to gain positive improvements in physical function.

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.

The effects of physical exercise in the palliative care phase for people with advanced cancer: a systematic review with meta-analysis

PURPOSE

The purpose of this systematic review with meta-analysis was to evaluate the safety, feasibility and effectiveness of exercise in the palliative care phase for people with advanced cancer.

METHODS

Electronic databases were searched for exercise randomised controlled trials involving individuals with incurable cancer that were published prior to April 14, 2021. Meta-analyses were performed to evaluate the effects of exercise on health outcomes. Subgroup effects for exercise mode, supervision, intervention duration and cancer diagnosis were assessed.

RESULTS

Twenty-two trials involving interventions ranging between 2 weeks and 6 months were included. Interventions comprised of aerobic (n = 3), resistance (n = 4), mixed-mode (n = 14) and other exercise (n = 1) modalities. Cancer types consisted of lung (n = 6), breast (n = 3), prostate (n = 2), multiple myeloma (n = 1) and mixed cancer types (n = 10). Meta-analysis of 20 RCTs involving 1840 participants showed no difference in the risk of a grade 2-4 adverse event between exercise and usual care (n = 110 adverse events (exercise: n = 66 events; usual care: n = 44 events), RD =  - 0.01 (91% CI =  - 0.01, 0.02); p = 0.24). Overall median recruitment, retention and adherence rates were 56%, 80% and 69%, respectively. Meta-analysis of health outcomes showed effects in favour of exercise for quality of life, fatigue, aerobic fitness and lower-body strength (SMD range = 0.27-0.48, all p < 0.05).

CONCLUSIONS

Participants who engaged in exercise experienced an increase in quality of life, fitness and strength and a decrease in fatigue.

IMPLICATIONS FOR CANCER SURVIVORS

Physical activity programs were found to be safe and feasible for people with advanced cancer in the palliative care phase.

Safety, Feasibility, and Efficacy of Exercise Interventions for People With Multiple Myeloma: A Systematic Review

Bone lesions and other disease- and treatment-related side effects commonly experienced by people with multiple myeloma (MM) may impede their ability to exercise. This systematic review evaluated the safety, feasibility, and efficacy of exercise program participation on the physiological and/or psychological health of people with MM. Literature searches were conducted through five electronic databases and appraised using the Delphi list of criteria. Controlled trials that assessed the safety and feasibility of an exercise intervention and its effects on disease- or treatment-related symptoms in people with MM were included. Seven studies of varying quality involving 563 participants were included. All studies concluded that exercise was safe, reporting zero serious and 4 adverse events attributable to exercise testing or training. Attendance ranged from 58% to 96%, however no study reported adherence to the exercise prescription. Compared to a control group, exercise did not appear to affect fatigue, depression, anxiety, body composition, quality of life, or sleep. Isolated studies identified between-group differences favoring exercise in lower limb strength (+8.4 kg, 95% CI 0.5, 16.3, P= .04), peak oxygen uptake (+1.2 mL/kg/min, 95% CI 0.3, 3.7, P= .02), physical activity (+6.5MET-hs/wk, P< .001), stem cell collection attempts (1.1 ± 0.2 vs. 1.5 ± 0.9, P< .01), and red blood cell (1.8 ± 2.2 vs. 2.4 ± 2.6, P< .05) and platelet transfusions (2.3 ± 1.6 vs. 3.5 ± 3.4, P < .05) during transplantation. Exercise interventions appear safe and well attended by people with MM. The lack of improvements in disease- and treatment-related symptoms requires further exploration to determine whether exercise is a sufficient stimulus to elicit benefits in this unique population.

Fascia training in patients undergoing allogeneic hematopoietic cell transplantation-a pilot study

PURPOSE

Patients undergoing allogeneic hematopoietic cell transplantation (alloHCT) spend many weeks of treatment in an isolated environment with little room for exercise. Feasibility of a daily-performed, unassisted fascia-training program and its effects on back and foot pain, back flexibility, and quality of life were investigated.

METHODS

Eighteen patients receiving alloHCT were randomized to an intervention (IG: n = 9; 60.7 ± 9.2 years) or control group (CG: n = 9; 54.0 ± 15.5 years) and assessed from 1 week before to 3 weeks after transplantation (t0-t3). CG received standard care physical therapy, IG performed additionally fascia training for the back and feet twice daily. Back and foot pain, back flexibility, muscle tone, and quality of life were assessed for both IG and CG at baseline and three timepoints after alloHCT.

RESULTS

Fascia-training program was well accepted. No increase in hematoma formation was observed. IG reported a trend towards reduction in back pain from pre- to post-intervention (p = .074), whereas CG showed a slight increase in back pain at t3 (p = .257). IG also improved back flexibility (- 1.79 ± 5.5 cm; p = .397) while CG declined (+ 2.71 ± 5.6 cm; p = .167). No differences between groups were found for muscle tone and no significant improvements in quality of life were reported at t3.

CONCLUSION

Unassisted fascia training is feasible and safe for patients undergoing alloHCT. This pilot study suggests that fascia training has the potential to improve back flexibility and reduce back pain, and might be a valuable component for physical therapy in patients receiving alloHCT.

Effects of Exercise Programs on Psychoemotional and Quality-of-Life Factors in Adult Patients with Cancer and Hematopoietic Stem Cell Transplantation or Bone Marrow Transplantation: A Systematic Review

This review analyzed the effects of an exercise program on psychoemotional and quality-of-life (QoL) factors in adult patients with cancer and hematopoietic stem cell transplantation (HSCT) or bone marrow transplantation (BMT). Studies were identified from the PubMed and Web of Science databases (from inception to 24 August 2022), according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. The methodological quality of the included studies was assessed with the Physiotherapy Evidence Database (PEDro) scale, based in turn on the Delphi list. A total of 20 randomized controlled studies were included with 1219 participants. The main result of this systematic review is that exercise program interventions produce improvements on psychoemotional and QoL factors in adult patients with cancer and HSCT or BMT. Moreover, exercise programs may have a beneficial effect on health, maintaining or increasing the patient's QoL. Further, it has a positive effect on the prevention and control of transplant complications in combination with medical treatment.

Effect of a 6-Week Cycle of Nordic Walking Training on Vitamin 25(OH)D3, Calcium-Phosphate Metabolism and Muscle Damage in Multiple Myeloma Patients-Randomized Controlled Trial

Introduction: Multiple myeloma (MM) is a hematological malignancy affecting older adults. One of the most common myeloma-defining events is the development of symptomatic lytic bone disease. The serum concentrations of calcium (Ca), inorganic phosphorus (P), and vitamin 25(OH)D3 in the serum reflect bone metabolism. An enzyme lactate dehydrogenase (LDH) is a marker of muscle damage, but its serum activity also has an important prognostic value in MM. Myoglobin (Mb) is a small protein present in muscles; its serum level increases when myocytes are damaged. Objectives: In this study, the impact of a 6-week Nordic walking (NW) exercise program on blood parameters related to calcium-phosphate metabolism and damage of skeletal muscles was assessed. Patients and methods: A total of 33 patients with MM in the remission stage, without cytostatic treatment, were allocated and randomly assigned to one of two groups: 17 in the training group (NW) and 16 in the control group (CG). All patients were supplemented per os with vitamin D3 and calcium carbonate daily and received zoledronic acid every 4 weeks (intravenous). Nordic walking training sessions took place 3 times a week for 6 weeks, 1 h each. Blood samples were drawn before and after the 6 weeks of training sessions to assess the serum concentrations of vitamin 25(OH)D3, P, Ca, Mb, and LDH. Results: Patients from the NW group showed a statistically significant decrease in mean serum myoglobin concentration (p = 0.018) and an increase in 25(OH)D3 (p < 0.001) and total Ca (p = 0.001) concentrations. There were no statistically significant changes in the results obtained in CG. Between groups, after 6 weeks, Mb serum concentration was significantly lower in NW (p = 0.041), and 25(OH)D3 was higher (p < 0.001) compared to CG. There was a correlation between the changes in myoglobin, phosphorus, 25(OH)D3, and Ca concentrations after 6 weeks. Conclusions: NW training is a safe and beneficial form of physical exercise for patients with MM without inducing muscle damage. NW performed outside improves serum vitamin 25(OH)D3 concentration.

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.

Bewegungstherapie bei nicht-heilbaren, fortgeschrittenen Krebserkrankungen

Dank der Entwicklung neuer Chemotherapie-Protokolle und verbesserter zielgerichteter Therapiestrategien hat sich das Überleben von Patienten mit nicht-heilbaren, fortgeschrittenen Krebserkrankungen deutlich verlängert. Durch die krankheitsbedingten Symptome und die zusätzlichen therapiebedingten Nebenwirkungen wird die Lebensqualität dieser Patienten aber deutlich eingeschränkt. Übersichtsarbeiten zeigen, dass auch Patienten mit nicht-heilbaren, fortgeschrittenen Krebserkrankungen von angepasster Bewegungstherapie profitieren können. Es wurde eine Literaturrecherche mithilfe elektronischer Datenbanken (PubMed, MEDLINE, EMBASE, Cochrane Library) durchgeführt und eine Übersicht der randomisierten kontrollierten Studien (RCTs) zur Bewegungstherapie bei nicht-heilbaren, fortgeschrittenen Krebserkrankungen gegeben. Die dargestellten Studien zeigen, dass eine gezielte Bewegungstherapie bei Patienten mit nicht-heilbaren, fortgeschrittenen Krebserkrankungen sicher und durchführbar ist und positive Effekte auf die Lebensqualität, auf krankheits- und therapiebedingte Symptome wie Fatigue, Dyspnoe und auf den körperlichen Funktionsstatus erzielen kann. Der Artikel beinhaltet außerdem einen Diskurs mit einem Praxisbezug zum Thema Knochenmetastasen.

Myeloma patients’ experiences of a supervised physical activity programme: a qualitative study

Purpose

The Myeloma: Advancing Survival Cancer Outcomes Trial (MASCOT) tested the impact of a supervised exercise programme on fatigue, clinical, and patient-reported outcomes in multiple myeloma [MM] patients. The current study explored MM patients’ experiences of the programme to guide future interventions.

Methods

Purposive sampling was used to recruit stable MM patients participating in MASCOT. Semi-structured, face-to-face interviews were conducted, transcribed verbatim, and analysed using thematic analysis.

Results

Six themes were identified. Key drivers for participation in MASCOT were “Altruism and extended cancer care”; participants wanted to give something back and assist in improving post-treatment care for MM patients, especially as after treatment “Barriers to being physically active” were a fear of damage and lack of health professional guidance. “Influences fostering change within the intervention” included physiotherapy supervision and tailored exercises, which gave participants confidence to push themselves in a safe environment and broke down misconceptions about their body. “Social support”, from both family and peers in the programme, promoted motivation and adherence. Participants expressed concerns about “Maintaining things going forward” but had identified mechanisms to aid continuation. “Physical and mental benefits” of the programme were highlighted; participants were able to do things they couldn’t before and described feeling free from the constraints of MM.

Conclusions

A post-treatment exercise intervention for MM patients was a positive experience, which enhanced participants’ physical and psychological wellbeing. Tailored gym and home-based exercises, a specialist cancer physiotherapist, and sustained support were perceived to be important for success.

Implications for cancer survivors

Exercise support for MM patients, ideally with physiotherapist supervision, should be incorporated into survivorship care to qualitatively improve patients’ quality of life, self-efficacy, and mental wellbeing.

Effects of Luteinizing Hormone Releasing Hormone A2 on Gonad Development in Juvenile Amur Sturgeon, Acipenser schrenckii, Revealed by Transcriptome Profiling Analysis

Acipenser schrenckii is an economically important aquatic species whose gonads require particularly long times to reach sexual maturity. Luteinizing hormone plays important roles in gonad development, and luteinizing hormone releasing hormone A2 (LH-A2) is used as an oxytocin to promote ovulation in aquaculture of A. schrenckii. In this study, we aimed to determine the effects of LH-A2 on gonad development in juvenile A. schrenckii through transcriptome profiling analysis of the pituitary and gonads after LH-A2 treatment at a dose of 3 μg/kg. The 17β-estradiol (E2) levels gradually increased with LH-A2 treatment time, and significantly differed from those of the control group on days 5 and 7 (p < 0.01). However, the content of testosterone (Testo) gradually decreased with LH-A2 treatment time and showed significant differences on day 3 (p < 0.05), and on days 5 and 7 (p < 0.01), compared to those in the control group. Thus, LH-A2 promotes the secretion of E2 and inhibits the secretion of Testo. Transcriptome profiling analysis revealed a total of 2,883 and 8,476 differentially expressed genes (DEGs) in the pituitary and gonads, respectively, thus indicating that LH-A2 has more regulatory effects on the gonads than the pituitary in A. schrenckii. Signal transduction, global and overview maps, immune system, endocrine system and lipid metabolism were the main enriched metabolic pathways in both the pituitary and gonads. Sixteen important genes were selected from these metabolic pathways. Seven genes were co-DEGs enriched in both signal transduction and endocrine system metabolic pathways. The other co-DEGs were selected from the immune system and lipid metabolism metabolic pathways, and showed mRNA expression changes of >7.0. The expression of five DEGs throughout LH-A2 treatment was verified to show the same patterns of change as those observed with RNA-seq, indicating the accuracy of the RNA-seq in this study. Our findings provide valuable evidence of the regulation of gonad development of juvenile A. schrenckii by LH-A2 and may enable the establishment of artificial techniques to regulate gonad development in this species.

Feasibility of implementing an exercise intervention in older adults with hematologic malignancy

Older adults with Hematologic Malignancy (HM) are vulnerable to functional decline secondary to disease and treatment. Interventions for physical deconditioning, in concert with routine hematology care are limited. The feasibility of accrual, retention, and demand for an exercise intervention among a high-risk HM population was piloted.

METHODS

Older adults with HM, on active treatment, with functional impairment were recruited prospectively to participate in a 6-month Otago Exercise Programme (OEP). Measures of motivation, self-efficacy, patient identified barriers to exercise, barriers to clinical trial enrollment, study satisfaction, and serious adverse events were captured.

RESULTS

63 patients were approached, 18 declined trial enrollment, 45 consented, 30 patients enrolled in the exercise program. The main barrier for trial enrollment was transportation/travel concerns (n = 15). Of the 45 consented participants, 8 (12.7%) dropped out due to clinical deterioration, 5 (7.9%) withdrew, and 2 (3.2%) were ineligible prior to exercise-intervention intiation. The median age was 75.5 years (range 62-83) with plasma cell dyscrasia (63%), non-Hodgkin lymphoma (20%) and leukemia (17%). Retention of the physical therapist (PT) led-OEP was 76.6% of patients (n = 23/30), and end-of-study retention was 66.7% (n = 20/30). Of the evaluable patients, 23/29 completed the PE-led OEP yielding a completion rate of 79%. Participants were extremely motivated (72.4%) and strongly intended (89.7%) to engage in regular physical activity. Exercising when tired increased from a median score of 50 at Visit 1 to 70 at Visit 2, but dropped significantly to 45 at Visit 3 (p < 0.001). Participants reported significantly lower self-efficacy to exercise over the next 6 months from Visit 1 to Visit 3 (p = 0.001).

CONCLUSIONS

Older patients with HM had higher completion of in-person, PT-led exercise compared to at-home, independent exercise. Older adults were motivated and found the program acceptable, yet the ability to sustain a structured exercise program was challenging due to changes in health status.

An Individualized Exercise Intervention for People with Multiple Myeloma—Study Protocol of a Randomized Waitlist-Controlled Trial

People with multiple myeloma (MM) are second only to people with lung cancer for the poorest reported health-related quality of life (HRQoL) of all cancer types. Whether exercise can improve HRQoL in MM, where bone pain and lesions are common, requires investigation. This trial aims to evaluate the efficacy of an exercise intervention compared with control on HRQoL in people with MM. Following baseline testing, people with MM (n = 60) will be randomized to an exercise (EX) or waitlist control (WT) group. EX will complete 12-weeks of supervised (24 sessions) and unsupervised (12 sessions) individualized, modular multimodal exercise training. From weeks 12–52, EX continue unsupervised training thrice weekly, with one optional supervised group-based session weekly from weeks 12–24. The WT will be asked to maintain their current activity levels for the first 12-weeks, before completing the same protocol as EX for the following 52 weeks. Primary (patient-reported HRQoL) and secondary (bone health and pain, fatigue, cardiorespiratory fitness, muscle strength, body composition, disease response, and blood biomarkers) outcomes will be assessed at baseline, 12-, 24- and 52-weeks. Adverse events, attendance, and adherence will be recorded and cost-effectiveness analysis performed. The findings will inform whether exercise should be included as part of standard myeloma care to improve the health of this unique population.

Effects of Exercise Programs on Physical Factors and Safety in Adult Patients with Cancer and Haematopoietic Stem Cell Transplantation: A Systematic Review

This study looks at the effects of exercise programs on physical factors and safety in adult patients with cancer and hematopoietic stem cell transplantation (HSCT) or bone marrow transplantation (BMT). A systematic search was performed in the PubMed and Web of Science databases (from inception to 26 August 2021). A review was carried out following the Preferred Reporting Items for Systematic review and Meta-Analyses (PRISMA) checklist. The methodological quality of the included studies was assessed with the Physiotherapy Evidence Database (PEDro) scale, based, in turn, on the Delphi list. A total of 25 randomized controlled trials studies were included, comprising 1434 patients. The most significant result of this systematic review is that exercise program interventions are safe and produce positive changes in cardiorespiratory fitness, muscle strength, and the functional mobility-state in adult patients with cancer and HSCT or BMT. Only 3 patients from the 711 participants in the exercise interventions (i.e., 0.42%) reported adverse events related to exercise interventions. Moreover, exercise training programs may have a cardiological and muscular protective effect, as well as a healthy effect on the prevention and control of transplant complications, improving health outcomes.

Effect of Rehabilitation Nutrition Care Process on Physical Function in Lung Cancer Cachexia: A Case Report

OBJECTIVES

Patients with cancer cachexia have poor adherence to treatment, which affects their prognosis. Currently, there are many studies on the effects of rehabilitation on cancer cachexia, but there is a lack of evidence on the effects of nutrition therapy alone or in combination with rehabilitation and nutrition therapy. This article describes a case in which rehabilitation nutrition care process was effective in a patient with lung cancer who developed cancer cachexia.

METHODS

A 68-year-old woman was hospitalized for treatment of lung adenocarcinoma. The patient had moderate malnutrition, sarcopenia, and cachexia at the time of admission, so the authors intervened according to rehabilitation nutrition care process. The physiotherapist mainly prescribed resistance training and aerobic exercise, 40-60 minutes a day, 5-6 days a week. And the dietitian provided oral nutritional supplements (100 kcal, branched-chain amino acid: 3.0 g) in addition to hospital food and adjusted the patient's energy intake to 26.96-33.05 kcal/kg/day and protein intake to 1.07-1.14 g/kg/day.

OUTCOMES

Comparing the initial evaluation with the discharge, nutritional status, such as body mass index and skeletal muscle mass, and physical functions, such as maximum grip strength, gait speed, and functional independence measure (motor items), were improved.

CONCLUSIONS

Rehabilitation nutrition care process-based interventions may improve nutritional status and physical functions more than exercise therapy alone in patients with lung cancer cachexia.

Clinical exercise therapy program with multiple myeloma patients: Impacts on feasibility, adherence and efficacy

PURPOSE

Multiple myeloma (MM) is a severe hemato-oncological disease with high mortality and increasing incidence rate. Since evidence on exercise therapy in MM patients remains limited, this study examines feasibility, adherence, and efficacy based on real-life data from an oncologic care structure.

METHODS

A data evaluation of MM patients who participated in the oncologic exercise and movement therapy (OTT) at the Cologne University Hospital between 2012 and 2019 was conducted. The patient flow was incrementally reduced to four cohorts, intention-to-treat cohort (ITTC), safety cohort (SC), adherence cohort (AC), and efficacy cohort (EC). Cohorts were evaluated descriptively and by means of correlation analysis as well as group and time comparisons.

RESULTS

Thirty patients registered at the OTT between 2012 and 2019 (ITTC). The SC (N = 26) attended exercise therapy on average about one session per week over a period of 8 months. One-third dropped out within 3 months. In the AC (N = 15), BMI at baseline exhibited a strong and very significant negative correlation with exercise adherence. In the EC (N = 8), a significant improvement in physical functioning and a tendency towards significance in fatigue reduction between two measurement points was observed. No adverse events were documented.

CONCLUSIONS

The present observatory study reveals safety and feasibility while indicating adherence and efficacy of exercising MM patients under real-life therapy circumstances. Found obstacles to exercising as well as improvements in questionnaire scale scores need to be further examined in confirmatory study designs.

Reduced Cancer-Related Fatigue after Tablet-Based Exercise Education for Patients

AIM

Exercise can be an effective treatment for cancer-related fatigue, but exercise is not prescribed for many cancer patients. Our specific aim was to compare usual care and a tablet-based fatigue education and prescription program for effects on level of fatigue (primary outcome) and satisfaction with fatigue and amount of exercise (secondary outcomes).

METHODS

In a four-week pretest/posttest randomized study, 279 patients with cancer completed a touch screen fatigue assessment and daily paper-based activity logs. The experimental group also had access to FatigueUCope, a tablet-based multimedia education intervention focused on exercise as therapy for fatigue.

RESULTS

In total, 94% of intervention group accessed FatigueUCope. Controlling for baseline fatigue, compared to the usual-care group, the experimental group reported lower fatigue scores (P = .02). Neither satisfaction with fatigue nor exercise level was significantly different between groups, but not all activity logs were returned. None of the patients reported adverse effects.

CONCLUSION

Objective indicators of exercise are warranted in future studies to examine whether exercise is indeed the mechanism of the FatigueUCope effect and determine the clinical utility of this intervention. This brief, engaging tablet-based multimedia education and prescription program has promise to help patients recognize the benefits of exercise to manage cancer-related fatigue.

Attention to principles of exercise training: an updated systematic review of randomized controlled trials in cancers other than breast and prostate

BACKGROUND

The primary objective of this systematic review was to update our previous review on randomized controlled trials (RCTs) of exercise in cancers other than breast or prostate, evaluating: 1) the application of principles of exercise training within the exercise prescription; 2) reporting of the exercise prescription components (i.e., frequency, intensity, time, and type (FITT)); and 3) reporting of participant adherence to FITT. A secondary objective was to examine whether reporting of these interventions had improved over time.

METHODS

MEDLINE, EMBASE, CINAHL and SPORTDiscus databases were searched from 2012 to 2020. Eligible studies were RCTs of at least 4 weeks of aerobic and/or resistance exercise that reported on physiological outcomes relating to exercise (e.g., aerobic capacity, muscular strength) in people with cancer other than breast or prostate.

RESULTS

Eighty-six new studies were identified in the updated search, for a total of 107 studies included in this review. The principle of specificity was applied by 91%, progression by 32%, overload by 46%, initial values by 72%, reversibility by 7% and diminishing returns by 5%. A significant increase in the percentage of studies that appropriately reported initial values (46 to 80%, p < 0.001) and progression (15 to 37%, p = 0.039) was found for studies published after 2011 compared to older studies. All four FITT prescription components were fully reported in the methods in 58% of all studies, which was higher than the proportion that fully reported adherence to the FITT prescription components in the results (7% of studies). Reporting of the FITT exercise prescription components and FITT adherence did not improve in studies published after 2011 compared to older studies.

CONCLUSION

Full reporting of exercise prescription and adherence still needs improvement within exercise oncology RCTs. Some aspects of exercise intervention reporting have improved since 2011, including the reporting of the principles of progression and initial values. Enhancing the reporting of exercise prescriptions, particularly FITT adherence, may provide better context for interpreting study results and improve research to practice translation.

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.

Impact of an allied health prehabilitation service for haematologic patients receiving high-dose chemotherapy in a large cancer centre

Purpose

Evaluate the impact of a new multidisciplinary allied health prehabilitation service in haematologic cancer patients receiving high-dose chemotherapy with autologous stem cell transplant (AuSCT).

Methods

In a tertiary cancer centre, 12 months of prospectively collected data was retrospectively analysed. Patients were referred to an allied health service for individualised exercise prescription, nutrition intervention and, if indicated through screening, psychological intervention. Impact and operational success were investigated using the RE-AIM framework: patient uptake of the service and sample representativeness (reach); effectiveness in terms of changes in outcomes from initial to pre-transplant assessment; adoption of the service by key stakeholders; fidelity of the prescribed exercise program (implementation); and the extent to which the new service had become routine practice (maintenance).

Results

One hundred and eighty-three patients were referred to the AuSCT service over 12 months, of whom 133 (73%) were referred into the prehabilitation service, 128 (96%) were eligible and 116 (91%) participated. Patients were representative of Australian AuSCT patients. Eighty-nine patients reached pre-transplant assessment by data censoring; 6-min walk distance (n = 45/89, 51%) improved a mean (95% CI) of 39.9 m (18.8 to 61.0, p =  < 0.005) from baseline. Fidelity of exercise prescription was moderate with 72% of eligible patients receiving the intended exercise interventions. The referral trend over time (maintenance) was high after the initiation period.

Conclusion

The prehabilitation service was well adopted by clinicians. Clinically relevant improvements in outcomes were demonstrated. Recommendations, including development of well-integrated discipline-specific assessment intervention and measurement protocols, are highlighted for service improvement. Prehabilitation should be routinely considered to support patients undergoing AuSCT.

Feasibility and benefits of a structured prehabilitation programme prior to autologous stem cell transplantation (ASCT) in patients with myeloma; a prospective feasibility study

Evidence supports the benefits of exercise-based rehabilitation in promoting recovery in myeloma patients following autologous stem-cell transplantation (ASCT). However, ‘prehabilitation’ has never been evaluated prior to ASCT, despite evidence of effectiveness in other cancers. Utilising a mixed method approach the authors investigated the feasibility of a mixed strength and cardiovascular exercise intervention pre-ASCT. Quantitative data were collected to determine feasibility targets; rates of recruitment, adherence and adverse events, including 6 minute walking distance (6MWD) test and patient reported outcome measures (PROMs). Qualitative interviews were undertaken with a purposive sample of patients to capture their experiences of the study and the intervention. The authors recruited 23 patients who attended a mean percentage of 75% scheduled exercise sessions. However, retention rates were limited, with only 14/23 (62%) completing the programme. In these patients, the 6MWD increased from a mean of 346 to 451 m (i.e. by 105 m, 95% CI 62 to 148 m) with no serious adverse events. Whist participants found the exercise programme acceptable and reported improvement in their physical fitness and overall mental health and wellbeing prior to ASCT, the study identified challenges in hospital attendance for the prehabilitation schedule whilst receiving induction or re-induction chemotherapy. Evaluation of digitally-enhanced directed but remote prehabilitation models for this patient group is warranted.

People With Hematological Malignancies Treated With Bone Marrow Transplantation Have Improved Function, Quality of Life, and Fatigue Following Exercise Intervention: A Systematic Review and Meta-Analysis

OBJECTIVE

For people with hematological malignancies treated with bone marrow transplantation (BMT), this systematic review aimed to identify, evaluate, and synthesize the evidence examining the effect of exercise training on the outcomes of exercise capacity, health-related quality of life (HRQoL), and hospital length of stay (LOS) and to identify any difference in the effect on people treated with allogeneic versus autologous transplantation.

METHODS

Five electronic databases were systematically searched from inception to December 5, 2020. Prospective studies with a comparator group, with or without randomization, were included if they investigated the effects of an exercise intervention compared with usual care or another intervention in adults who had a hematological malignancy and were undergoing BMT. Primary outcomes of interest were functional exercise capacity and HRQoL; secondary outcomes included strength, fatigue, hospital LOS, and feasibility. Only randomized controlled trials were included in the meta-analyses. Risk of bias was evaluated using the Physiotherapy Evidence Database or Newcastle-Ottawa Scale; the quality of evidence for meta-analyses was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach.

RESULTS

Twenty-four randomized controlled trials and 3 prospective nonrandomized experimental trials were included (n = 2432). There was moderate-quality evidence that exercise improves functional exercise capacity (mean difference [MD] = 29 m; 95% CI = 12.59 to 45.4), global HRQoL (MD = 3.38 points; 95% CI = 0.37 to 6.39), and fatigue (MD = 2.52 points; 95% CI = 0.42 to 4.63) and low-quality evidence for reduced hospital LOS (MD = 2.07 days; 95% CI = 0.43 to 3.72). These effects were more pronounced in recipients of allogeneic transplantation. No serious adverse events were associated directly with exercise in the included studies.

CONCLUSION

Exercise is safe and improves outcomes, including functional exercise capacity, HRQoL, and hospital LOS in adults undergoing BMT.

IMPACT

The results of this systematic review support the implementation of exercise programs in adults undergoing BMT, particularly recipients of allogeneic transplantation.

Recent Advances in Chemical Biology of Mitochondria Targeting

Mitochondria are vital subcellular organelles that generate most cellular chemical energy, regulate cell metabolism and maintain cell function. Mitochondrial dysfunction is directly linked to numerous diseases including neurodegenerative disorders, diabetes, thyroid squamous disease, cancer and septicemia. Thus, the design of specific mitochondria-targeting molecules and the realization of real-time acquisition of mitochondrial activity are powerful tools in the study and treatment of mitochondria dysfunction in related diseases. Recent advances in mitochondria-targeting agents have led to several important mitochondria chemical probes that offer the opportunity for selective targeting molecules, novel biological applications and therapeutic strategies. This review details the structural and physiological functional characteristics of mitochondria, and comprehensively summarizes and classifies mitochondria-targeting agents. In addition, their pros and cons and their related chemical biological applications are discussed. Finally, the potential biomedical applications of these agents are briefly prospected.

Prevention of Bone Destruction by Mechanical Loading Is Not Enhanced by the Bruton's Tyrosine Kinase Inhibitor CC-292 in Myeloma Bone Disease

Limiting bone resorption and regenerating bone tissue are treatment goals in myeloma bone disease (MMBD). Physical stimuli such as mechanical loading prevent bone destruction and enhance bone mass in the MOPC315.BM.Luc model of MMBD. It is unknown whether treatment with the Bruton’s tyrosine kinase inhibitor CC-292 (spebrutinib), which regulates osteoclast differentiation and function, augments the anabolic effect of mechanical loading. CC-292 was administered alone and in combination with axial compressive tibial loading in the MOPC315.BM.Luc model for three weeks. However, neither CC-292 alone nor its use in combination with mechanical loading was more effective in reducing osteolytic bone disease or rescuing bone mass than mechanical stimuli alone, as evidenced by microcomputed tomography (microCT) and histomorphometric analysis. Further studies are needed to investigate novel anti-myeloma and anti-resorptive strategies in combination with physical stimuli to improve treatment of MMBD.

Role of Physical Activity and Cardiac Rehabilitation in Patients Undergoing Hematopoietic Stem Cell Transplantation

Hematopoietic stem cell transplantation (HSCT) is a standard treatment for several malignancies, and >50,000 HSCT are performed annually worldwide. As survival after HSCT improves, cardiovascular disease and associated risk factors have gained importance as a significant cause of morbidity and mortality in this cohort. In this article, we detail the risk factors for cardiovascular disease and their impact in patients undergoing HSCT. Additionally, we critically review the data on the impact of physical exercise in patients undergoing HSCT. Although limited by significant heterogeneity in methodologies, small sample sizes, attrition, and lack of long-term cardiovascular follow-up, most of these studies reinforce the beneficial effects of physical activity and exercise in this patient population. Cardiac rehabilitation (CR) is a structured exercise and lifestyle modification program that is typically instituted in patients who experience acute cardiovascular events. We review the data on CR in the oncologic and nononcologic populations with an aim of building a framework for use of CR in HSCT patients.

The Immunostimulative Effect and Mechanisms of a Novel Mouse Anti-Human PD-1 Monoclonal Antibody on Jurkat Lymphocytic Cells Cocultured with Hepatoma Cells

BACKGROUND

Monoclonal antibodies (mAbs) that target the programmed cell death-1 (PD-1)/programmed death-ligand 1 (PD-L1) immune checkpoint have demonstrated substantial clinical benefit for a variety of solid tumors. However, their applications in patients with hepatocellular carcinoma (HCC) are reported with unclear molecular mechanisms. Here, we report a novel mouse anti-human PD-1 mAb that can reverse the immunosuppressive effect of HePG2 cells on Jurkat cells.

MATERIALS AND METHODS

HepG2 liver cancer cells, which were induced to overexpress PD-L1 by IFN-γ, were co-cultured with PHA-activated Jurkat lymphocytic cells to investigate the immunostimulative effect and mechanisms of the 14 newly generated PD-1 mAbs. Multiple cellular and molecular biology experiments were performed in this study, such as CCK-8, ELISA, flow cytometry, immunofluorescence and Western blot.

RESULTS

We found that mAb B1C4 significantly enhanced the tumor-killing cytokine secretion level by Jurkat cells in the co-culture system and increased the killing ability of Jurkat cells on HepG2 cells. Co-culture with HePG2 cells led to Jurkat cell cycle delay in S phase, and B1C4 promoted cell cycle progression from S to G2/M. Co-culture with HePG2 cells also caused apoptosis in Jurkat cells, which was inhibited by B1C4. B1C4 reversed the immunosuppression of Jurkat cells resulted from co-cultured with HePG2 cells through inhibiting PTEN and activating PI3K/AKT/mTOR signaling pathways.

CONCLUSION

Our study demonstrated that anti-PD-1 mAb B1C4 could inhibit the apoptosis of Jurkat cells induced by HePG2 hepatoma cells and reverse the immunosuppressive effect of HePG2 cells on Jurkat cells. The study provides a vital basis for applying PD-1 monoclonal antibodies in the treatment of HCC and provides antibody selection for the development of novel PD-1 mAb with blocking activity.

Exercise training (ET) in adult and elderly patients receiving anti-lymphoma treatments is feasible and may improve the provision of care

Lymphoma treatments can produce adverse effects leading to a reduced quality-of-life (QoL). Besides, in patients ≥65years, it can promote an accelerated geriatric decay. We conducted a prospective study on supervised Exercise-Training (ET), in consecutive, patients aged 18-80years, during anti-lymphoma treatments.16/30 (53%), median-age = 65.5y, participated to the ET sessions, this was the Interventional Group (IG); 14/30 (47%), median-age = 63y, were the Reference Group (RG). Both groups participated to the fitness and the QoL assessments, at baseline (T0), 3-months (T1) and 6-months (T2) after the start of chemotherapy. The adherence to the ET program was 50% (95% CI:36-64%). The IG showed substantial improvements compared to the CG in cardiorespiratory fitness (Cooper test) at both T1 and T2 and in all the functional domain of the QoL questionnaire (QLQ-C30) at T2. This study showed ET, during chemotherapy, is feasible and safe, even in patients ≥65 years. Furthermore, it may improve the provision of care.

Physical activity is associated with less comorbidity, better treatment tolerance and improved response in patients with multiple myeloma undergoing stem cell transplantation

OBJECTIVES

Multiple myeloma (MM) is the second most common hematological malignancy. Progression free survival (PFS) and overall survival (OS) have substantially improved, nonetheless MM usually remains incurable. Patients with active disease may be affected by numerous comorbidities, including fatigue, depression and osteolytic lesions, which influence their quality of life (QoL). Albeit, it is known that exercising is beneficial for patients' QoL, few clinical trials are available in patients with MM. We therefore aimed to compare comorbidities and clinical outcome in physically active and inactive patients with MM.

MATERIAL AND METHODS

We defined physical activity according to WHO criteria (150 min of moderate activity and two sessions of resistance training/week). We matched 53 physically active patients with 53 controls (for age, gender, cytogenetics, disease stage, and therapy) and compared the cohorts for incidence of comorbidities/MM symptoms (osteolytic lesions, anemia, infections, fatigue, depression, Revised-Myeloma Comorbidity Index [R-MCI]) and clinical outcome (treatment tolerance, responses to therapy, PFS and OS) in a retrospective audit. All patients were newly diagnosed with MM and received autologous stem cell transplantations (ASCT) between 2001 and 2017.

RESULTS

Physically active patients showed superior outcomes in R-MCI (p = 0.0005), fatigue (p = 0.0063), treatment tolerance (p = 0.0258) and hospital stays (p = 0.0072). Furthermore, they showed better treatment responses (p = 0.0366), especially complete remission (CR; p = 0.0018) as well as better OS and PFS.

CONCLUSION

Physical activity in patients with MM undergoing ASCT seemed associated with better overall clinical outcome. Randomized clinical trials are required to understand the benefits and devise strategies for improving exercising among patients with MM.

Effectiveness of aerobic exercise and mind-body exercise in cancer patients with poor sleep quality: A systematic review and meta-analysis of randomized controlled trials

Exercise has promising effects on sleep disturbances and quality of life among cancer patients. Aerobic exercises (AE) and mind-body exercises (MBE) have different mechanisms for improving sleep, but whether they are effective remains unclear. This systematic review and meta-analysis is the first to examine the effectiveness of AE and MBE on sleep outcomes, specifically among cancer patients with sleep disturbances. A systematic search of several databases, from inception to January 2018, was conducted. The pooled effect sizes suggested that both AE (standardized mean difference (SMD) = 0.33, 95% confidence intervals (CI): 0.11, 0.54) and MBE (SMD = 0.18, 95% CI: 0.06, 0.30), improved sleep outcomes in cancer patients with poor sleep quality post-intervention. The effects remained significant after 3-6 months for AE, but not MBE. Due to the heterogeneity in AE, future studies should establish the optimal AE prescription. For MBE, future research should study essential components that make the intervention effect sustainable.

Mobilization and Exercise Intervention for Patients With Multiple Myeloma: Clinical Practice Guidelines Endorsed by the Canadian Physiotherapy Association

OBJECTIVE

Individuals with multiple myeloma (MM) often have reduced functional performance due to the cancer itself or as a direct side effect of cancer treatments. Physical therapy is a part of cancer rehabilitation; however, no guidelines are available to provide information and direction for physical therapists managing patients with MM. The goal of this guideline is to provide recommendations based on a systematic review and consensus process that physical therapists can use to manage patients with MM.

METHODS

A systematic review of the literature published until August 2018 was performed in 8 databases with 2 independent reviewers assessing quality. Seventeen articles were identified as relevant, and a draft guideline was developed in the form of action statements. A total of 10 physical therapists with hematology experience and 10 patients with MM were recruited for consensus process. A priori threshold of 80% agreement was used to establish a consensus for each statement. The draft guidelines were reviewed externally by 4 methodologists using the AGREE II tool and a stakeholder representing OH (Cancer Care Ontario) Program in Evidence Based Care, McMaster University. The final guideline was reviewed and officially endorsed by the Canadian Physiotherapy Association.

RESULTS

A total of 30 action statements were developed that achieved consensus, indicating physical therapy recommendations based on physiological markers (ie, hemoglobin, platelet count), complete patient presentation, and the stage of medical treatment.

CONCLUSION

These clinical practice guidelines were developed to aid physical therapists in implementing evidence-based and best-practice care for patients with MM to optimize rehabilitation outcomes.

IMPACT

These guidelines fill an important knowledge gap and are the first to provide information specifically for physical therapist management of patients with MM.

Clinical utility of miRNA-1, miRNA-29g and miRNA-133s plasma levels in prostate cancer patients with high-intensity training after androgen-deprivation therapy

The randomized trials showed that the addition of training resistance program to androgen-deprivation therapy (ADT) had many beneficial effects for prostate cancer (PC) patients (significant protective effect on the volume of muscle mass) and the studies have revealed a panel of miRNAs, which are deregulate in PC and may serve as promising biomarkers of PC risk. The primary aim of our present study was to investigate the effect of exercise training to changes in body composition (muscle strength) and the secondary endpoint was to investigate the impact of an exercise training program on plasma levels of selected myogenic microRNAs (miRNAs) (miRNA-1, miRNA-29b, and miRNA-133) in PC patients undergoing the ADT. Effect of ADT and exercise intervention showed significant increase (experimental group vs. control group) the changes in body composition, free testosterone levels, IL-6 and plasma levels of myogenic miRNAs and significant reduced insulin serum levels. In conclusion, resistance training with ADT in the treatment of PC significantly changed the physical and metabolic function and the plasma levels of specific myogenic miRNAs. Our data support with the other publicized results.

Physical function in patients newly diagnosed with multiple myeloma; a Danish cohort study

BACKGROUND

Multiple myeloma is a cancer in the bone marrow causing bone destruction. Patients experience various symptoms related to the disease and/or treatment, such as pain and fatigue, leading to poorer quality of life. The symptom burden might affect physical function and physical activity levels, posing a risk of physical deterioration. The aim was to investigate whether physical function in newly diagnosed patients with multiple myeloma differs from the reference values of the normal population and other cancer patients.

METHODS

The study is a cross sectional descriptive analysis of a prospective cohort of 100 patients newly diagnosed with multiple myeloma. Four physical function tests were carried out; Six-Minute-Walk-Test, Sit-to-Stand-Test, grip strength and knee extension strength. Age and gender specific results of physical function from the multiple myeloma population were compared to normative data and to data from other cancer populations.

RESULTS

Of the 100 patients included, 73% had bone disease and 55% received pain relieving medicine. Mean age was 67.7 years (SD 10.3). Patients with multiple myeloma had significantly poorer physical function compared to normative data, both regarding aerobic capacity and muscle strength, although not grip strength. No differences in physical function were found between patients with multiple myeloma and other cancer populations.

CONCLUSIONS

Physical function in newly diagnosed Danish patients with multiple myeloma is lower than in the normal population. Exercise intervention studies are warranted to explore the value of physical exercise on physical function.

PERCEPT myeloma: a protocol for a pilot randomised controlled trial of exercise prehabilitation before and during autologous stem cell transplantation in patients with multiple myeloma

INTRODUCTION

Myeloma, a blood cancer originating from plasma cells, is the most common indication for autologous stem cell transplantation (SCT). Patients with myeloma undergoing autologous SCT (ASCT) experience treatment-related morbidity and reduction in function and well-being for many months post-treatment. Interventions targeting physical functioning delivered prior to and during SCT have shown promising results in mixed haematological populations and may offer a non-pharmacological solution to physically optimising and preparing patients for SCT. The aim of this study is to investigate the feasibility of a physiotherapist-led exercise intervention as an integral part of the myeloma ASCT pathway at a UK tertiary centre.

METHODS AND ANALYSIS

PERCEPT is a single-site, pilot randomised controlled trial of an exercise intervention embedded within the myeloma ASCT pathway, compared with usual care. The primary study end points will be feasibility measures of study and intervention delivery including recruitment rates, acceptability of intervention, study completion rate and any adverse events. Secondary end points will evaluate differences between the exercise intervention group and the usual care control group in cancer-related fatigue, quality of life, functional capacity (6 min walk test; handheld dynamometry; a timed sit-to-stand test) and objective and self-reported physical activity. Outcomes will be assessed at four time points, approximately 6-8 weeks prior to SCT, on/around day of SCT, on discharge from SCT hospital admission and 12 weeks post-discharge. The exercise intervention comprises of partly supervised physiotherapist-led aerobic and resistance exercise including behaviour change techniques to promote change in exercise behaviour. The primary outcomes from the trial will be summarised as percentages or mean values with 95% CIs. Group differences for secondary outcomes at each time point will be analysed using appropriate statistical models.

ETHICS AND DISSEMINATION

This study has NHS REC approval (Camden and Kings Cross, 19/LO/0204). Results will be disseminated through publication and presentations at haematology and rehabilitation-related meetings.

Whole body vibration training during allogeneic hematopoietic cell transplantation-the effects on patients' physical capacity

Patients undergoing allogeneic hematopoietic cell transplantation (alloHCT) experience a considerable decline in physical and psycho-social capacity. Since whole body vibration (WBV) is known to efficiently stimulate the neuromuscular system and enhance cardiorespiratory fitness and muscle strength in frail individuals, we hypothesized that WBV would maintain various physical and psychological capacities in patients during alloHCT. Seventy-one patients were randomly allocated to either an intervention group (IG) doing WBV or an active control group (CG) doing mobilization exercises five times per week. We determined peak oxygen consumption (VO_2peak) and maximum power, maximum strength, functional performance, body composition, quality of life (QoL), and fatigue. Tests were carried out before conditioning therapy, at hospital discharge and at day ± 180 (follow-up). As 18 patients did not participate in post-intervention assessment and follow-up data from 9 patients was not collectible, per-protocol (PP) analysis of 44 patients is presented. During hospitalization, WBV maintained maximum strength, height, and power output during jumping, as well as reported QoL, physical functioning, and fatigue level compared with mobilization. At follow-up, relative VO_2peak (p = 0.035) and maximum power (p = 0.011), time and power performing chair-rising test (p = 0.022; p = 0.009), and reported physical functioning (p = 0.035) significantly increased in the IG, while fatigue decreased (p = 0.005). CG’s body cell mass and phase angle had significantly decreased at follow-up (p = 0.002; p = 0.004). Thus, WBV might maintain maximum strength, functional performance, QoL, and fatigue during alloHCT, while cardiorespiratory fitness might benefit from accelerated recovery afterwards.

Therapeutic Education and Physical Activity to Support Self-management of Cancer-related Fatigue in Hematologic Cancer Patients: Protocol of a Feasibility Randomized Controlled Trial

INTRODUCTION

Hematologic malignancies account for nearly 8% of new cancer diagnosis in Italy. Cancer-related fatigue (CRF) is one of the most distressing symptoms reported by patients with cancer. As CRF has a multifactorial etiology, physical activity and therapeutic education may be beneficial for managing CRF, both during and after cancer treatment. However, there is a lack of evidence specific to hematologic malignancies. This paper describes the protocol of a feasibility study on Therapeutic Education and Physical Activity (TEPA) intervention to support self-management of CRF in patients with hematologic malignancies.

METHODS

TEPA was addressed to newly diagnosed adult individuals with hematologic malignancy able to take part in a rehabilitation programme at the AUSL-IRCCS of Reggio Emilia. The protocol was developed in 2 phases. Phase I was an observational cohort study involving a convenience sample of 10 participants with the aim to evaluate the feasibility of the assessment schedule and to register longitudinal clinical data regarding CRF (FACIT-F), psychologic distress (NCCN Distress Thermometer), QoL (EORTC QLQ-C30), physical performance (TUG and 6MWT) and habitual level of physical activity during first months after diagnosis. Phase II (underway) is a feasibility randomized controlled trial (TEPA) involving a convenience sample of 40 participants and comparing 2 parallel active interventions (Therapeutic Education versus Therapeutic Education and Physical Activity) on top of usual care. The primary aim is to estimate the feasibility of TEPA, measured by the adherence rate to the intervention. Secondary aims are: to estimate the effect size of TEPA in terms of changes in CRF, psychological distress, QoL, physical performance and habitual level of physical activity (measured as in Phase I); to collect patient satisfaction, perception of usefulness of the TEPA intervention and data on long-term adherence to an active lifestyle. Data are collected in both phases at the time of diagnosis and then at 1-, 3- (completion of intervention) and 7-month follow-up.

DISCUSSION

Data on feasibility and effect size of TEPA will be analyzed upon completion of Phase II, allowing us to design a large, adequately powered RCT to verify the effectiveness of this intervention on CRF management in patients with hematologic cancer.

Relevant parameters for recommendations of physical activity in patients suffering from multiple myeloma : A pilot study

Purpose

This pilot study aimed to describe physical performance, self-reported physical activity, health-related quality of life, anxiety and depression in patients who were assigned from Austrian self-help groups for multiple myeloma patients. These parameters were then discussed in the context of clinical decision-making concerning the recommended type of regular physical activity and exercise.

Methods

Members of the self-help groups were invited to participate. Physical performance and physical activity were assessed with the 6 min walk test (6MWT), handgrip strength test, timed up and go test (TUG), Tinetti performance oriented mobility assessment (POMA), falls efficacy scale (FES), international physical activity questionnaire (IPAQ), health-related quality of life (EORTC QLQ-C30) and the hospital anxiety and depression scale (HADS).

Results

A total of 40 patients (female:male = 15:25, mean age: 63.8 ± 9.0 years, range 41–80 years) were identified. In total 20 (50%) reached the performance of healthy peers in the tests 6MWT, handgrip strength, TUG and POMA, while 50% showed at least 1 result below the reference value or cut-off-point for each test. Self-reported activity levels were high. Patients showed a tendency to overestimate the risk of falling but a case by case analysis revealed a tendency for underestimating the actual performance in the respective tests (TUG, POMA).

Conclusion

The performance of healthy peers was reached by a substantial number of the participants in tests of physical performance and they reported high levels of physical activity. Nevertheless, they tended to overestimate the specific risk of falling. Patients with notably impaired physical performance might be suitable to perform regular physical activity and exercise in an individual therapy, whereas those with good physical performance are suited for training in exercise groups; however, individual contraindications and clinical considerations should be noted in a multiprofessional and interdisciplinary setting.

Supervised and home-based physical exercise in patients newly diagnosed with multiple myeloma-a randomized controlled feasibility study

Background

The study evaluated the feasibility and safety of the exercise intervention and physical test procedures of our ongoing randomized controlled trial, examining the effect of physical exercise in newly diagnosed patients with multiple myeloma.

Methods

Patients are randomized 1:1 to a control group (usual care) or an intervention group (usual care and exercise) by block randomization with stratification of planned treatment, WHO performance status, and study site. The exercise intervention consists of eight supervised exercise sessions combined with home-based exercise over a 10-week period. Bone disease is systematically evaluated to determine limitations regarding physical testing and/or exercise. Feasibility outcome measures were study eligibility, acceptance, and attrition, and furthermore attendance, adherence, tolerability, and safety to the exercise intervention. Additionally, test completion, pain, and adverse events during the physical test procedures were evaluated. Outcome assessors were blinded to allocation.

Results

Of 49 patients screened, 30 were included. The median age was 69 years, range 38–90, 77% were males, and 67% had bone disease. Study eligibility was 82%, acceptance 75%, and attrition 20%. Attendance at supervised exercise sessions was 92%, and adherence to supervised exercise sessions and home-based exercise sessions was 99% and 89%, respectively. No serious adverse events attributed to exercise or physical tests were reported. All patients completed the physical tests, except for two patients, where physical test procedures were modified due to bone disease.

Discussion

The exercise intervention and physical test procedures were feasible and safe in patients with multiple myeloma, even in older patients with multiple myeloma and in patients with myeloma bone disease.

Physical activity and health-related quality of life in multiple myeloma survivors: the PROFILES registry

OBJECTIVES

To investigate whether physical activity (PA) is associated with health-related quality of life (HRQOL) outcomes in multiple myeloma (MM) survivors up to 11 years after diagnosis.

METHODS

We used data from the Patient Reported Outcomes Following Initial treatment and Long term Evaluation of Survivorship registry. We included 175 MM survivors diagnosed between 1999 and 2009 as registered by the Netherlands Cancer Registry. Sixty-four per cent (n=112/175) of patients who received the questionnaires, completed the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 and the EORTC QLQ-MY20. Patients were classified into two groups: physically active and not physically active patients. Univariable and multivariable linear regression models were used to evaluate associations between PA and HRQOL outcomes.

RESULTS

Physically active patients reported a statistically significant higher global health status/HRQOL (p=0.001), lower fatigue (p=0.002) and fewer side effects of treatments (p=0.001), than not physically active patients. PA was not associated with psychological symptoms (ie, anxiety and depressive symptoms) (anxiety: p=0.139; depressive symptoms: p=0.073). Exploratory analyses performed on the other scales of the EORTC QLQ-C30 indicated statistically significant better outcomes in several functional and symptom subscales for physically active patients.

CONCLUSIONS

These findings might contribute to a better understanding of the relationship between PA and disease specific HRQOL aspects in MM survivors. Prospective studies are warranted to further elucidate on the beneficial effects of PA on HRQOL outcomes of MM survivors.

Expression of genes that control core fucosylation in hepatocellular carcinoma: Systematic review

BACKGROUND

Changes in N-linked glycosylation have been observed in the circulation of individuals with hepatocellular carcinoma. In particular, an elevation in the level of core fucosylation has been observed. However, the mechanisms through which core fucose is increased are not well understood. We hypothesized that a review of the literature and related bioinformatic review regarding six genes known to be involved in the attachment of core fucosylation, the synthesis of the fucosylation substrate guanosine diphosphate (GDP)-fucose, or the transport of the substrate into the Golgi might offer mechanistic insight into the regulation of core fucose levels.

AIM

To survey the literature to capture the involvement of genes regulating core N-linked fucosylation in hepatocellular carcinoma

METHODS

The PubMed biomedical literature database was searched for the association of hepatocellular carcinoma and each of the core fucose-related genes and their protein products. We also queried The Cancer Genome Atlas Liver hepatocellular carcinoma (LIHC) dataset for genetic, epigenetic and gene expression changes for the set of six genes using the tools at cBioportal.

RESULTS

A total of 27 citations involving one or more of the core fucosylation-related genes (FPGT, FUK, FUT8, GMDS, SLC35C1, TSTA3) and hepatocellular carcinoma were identified. The same set of gene symbols was used to query the 371 patients with liver cancer in the LIHC dataset to identify the frequency of mRNA over or under expression, as well as non-synonymous mutations, copy number variation and methylation level. Although all six genes trended to more samples displaying over expression relative to under-expression, it was noted that a number of tumor samples had undergone amplification of the genes of the de novo synthesis pathway, GMDS (27 samples) and TSTA3 (78 samples). In contrast, the other four genes had undergone amplification in 2 or fewer samples.

CONCLUSION

Amplification of genes involved in the de novo pathway for generation of GDP-fucose, GMDS and TSTA3, likely contributes to the elevated core fucose observed in hepatocellular carcinoma.

Aerobic physical exercise for adult patients with haematological malignancies

BACKGROUND

Although people with haematological malignancies have to endure long phases of therapy and immobility, which is known to diminish their physical performance level, the advice to rest and avoid intensive exercises is still common practice. This recommendation is partly due to the severe anaemia and thrombocytopenia from which many patients suffer. The inability to perform activities of daily living restricts them, diminishes their quality of life and can influence medical therapy.

OBJECTIVES

In this update of the original review (published in 2014) our main objective was to re-evaluate the efficacy, safety and feasibility of aerobic physical exercise for adults suffering from haematological malignancies considering the current state of knowledge.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2018, Issue 7) and MEDLINE (1950 to July 2018) trials registries (ISRCTN, EU clinical trials register and clinicaltrials.gov) and conference proceedings. We did not apply any language restrictions. Two review authors independently screened search results, disagreements were solved by discussion.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) comparing an aerobic physical exercise intervention, intending to improve the oxygen system, in addition to standard care with standard care only for adults suffering from haematological malignancies. We also included studies that evaluated aerobic exercise in addition to strength training. We excluded studies that investigated the effect of training programmes that were composed of yoga, tai chi chuan, qigong or similar types of exercise. We also excluded studies exploring the influence of strength training without additive aerobic exercise as well as studies assessing outcomes without any clinical impact.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened search results, extracted data and assessed the quality of trials. We used risk ratios (RRs) for adverse events, mortality and 100-day survival, standardised mean differences (SMD) for quality of life (QoL), fatigue, and physical performance, and mean differences (MD) for anthropometric measurements.

MAIN RESULTS

In this update, nine trials could be added to the nine trials of the first version of the review, thus we included eighteen RCTs involving 1892 participants. Two of these studies (65 participants) did not provide data for our key outcomes (they analysed laboratory values only) and one study (40 patients) could not be included in the meta-analyses, as results were presented as changes scores only and not as endpoint scores. One trial (17 patients) did not report standard errors and could also not be included in meta-analyses. The overall potential risk of bias in the included trials is unclear, due to poor reporting.The majority of participants suffered from acute lymphoblastic leukaemia (ALL), acute myeloid leukaemia (AML), malignant lymphoma and multiple myeloma, and eight trials randomised people receiving stem cell transplantation. Mostly, the exercise intervention consisted of various walking intervention programmes with different duration and intensity levels.Our primary endpoint overall survival (OS) was only reported in one of these studies. The study authors found no evidence for a difference between both arms (RR = 0.67; P = 0.112). Six trials (one trial with four arms, analysed as two sub-studies) reported numbers of deceased participants during the course of the study or during the first 100 to 180 days. For the outcome mortality, there is no evidence for a difference between participants exercising and those in the control group (RR 1.10; 95% CI 0.79 to 1.52; P = 0.59; 1172 participants, low-certainty evidence).For the following outcomes, higher numbers indicate better outcomes, with 1 being the best result for the standardised mean differences. Eight studies analysed the influence of exercise intervention on QoL. It remains unclear, whether physical exercise improves QoL (SMD 0.11; 95% CI -0.03 to 0.24; 1259 participants, low-certainty evidence). There is also no evidence for a difference for the subscales physical functioning (SMD 0.15; 95% CI -0.01 to 0.32; 8 trials, 1329 participants, low-certainty evidence) and anxiety (SMD 0.03; 95% CI -0.30 to 0.36; 6 trials, 445 participants, very low-certainty evidence). Depression might slightly be improved by exercising (SMD 0.19; 95% CI 0.0 to 0.38; 6 trials, 445 participants, low-certainty evidence). There is moderate-certainty evidence that exercise probably improves fatigue (SMD 0.31; 95% CI 0.13 to 0.48; 9 trials, 826 patients).Six trials (435 participants) investigated serious adverse events. We are very uncertain, whether additional exercise leads to more serious adverse events (RR 1.39; 95% CI 0.94 to 2.06), based on very low-certainty evidence.In addition, we are aware of four ongoing trials. However, none of these trials stated, how many patients they will recruit and when the studies will be completed, thus, potential influence of these trials for the current analyses remains unclear.

AUTHORS' CONCLUSIONS

Eighteen, mostly small RCTs did not identify evidence for a difference in terms of mortality. Physical exercise added to standard care might improve fatigue and depression. Currently, there is inconclusive evidence regarding QoL, physical functioning, anxiety and SAEs .We need further trials with more participants and longer follow-up periods to evaluate the effects of exercise intervention for people suffering from haematological malignancies. To enhance comparability of study data, development and implementation of core sets of measuring devices would be helpful.

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.

Whole-Body Electromyostimulation Combined With Individualized Nutritional Support Improves Body Composition in Patients With Hematological Malignancies - A Pilot Study

Patients undergoing the complex treatment for hematological malignancies are exposed to a high physiological and psychological distress inducing fatigue and physical inactivity. In line with cancer-related metabolic changes patients are predisposed for skeletal muscle mass loss that leads to a functional decline, affects therapeutic success, and quality of life. Benefits of physical exercise and nutritional interventions on muscle maintenance are observed in solid cancer patients, but marginally investigated in patients with hematological cancer. We here studied the effects of a combined supportive exercise and nutrition intervention using whole-body electromyostimulation (WB-EMS) training and individualized nutritional support in patients actively treated for hematological malignancy. In a controlled pilot trial, 31 patients (67.7% male; 58.0 ± 16.7 years) with various hematological cancers were allocated to a control group (n = 9) receiving nutritional support of usual care regarding a high protein intake (>1.0 g/kg/d) or to a physical exercise group (n = 22) additionally performing WB-EMS training twice weekly for 12 weeks. Bodyweight and body composition assessed by bioelectrical impedance analysis were measured every 4 weeks. Physical function, blood parameters, quality of life and fatigue were assessed at baseline and after 12 weeks. No WB-EMS-related adverse effects occurred. Patients attending the exercise program presented a higher skeletal muscle mass than controls after 12-weeks (1.51 kg [0.41, 2.60]; p = 0.008). In contrast, patients of the control group showed a higher fat mass percentage than patients of the WB-EMS group (-4.46% [-7.15, -1.77]; p = 0.001) that was accompanied by an increase in serum triglycerides in contrast to a decrease in the WB-EMS group (change ± SD, control 36.3 ± 50.6 mg/dl; WB-EMS -31.8 ± 68.7 mg/dl; p = 0.064). No significant group differences for lower limb strength, quality of life, and fatigue were detected. However, compared to controls the WB-EMS group significantly improved in physical functioning indicated by a higher increase in the 6-min-walking distance (p = 0.046). A combined therapeutic intervention of WB-EMS and protein-rich nutritional support seems to be safe and effective in improving skeletal muscle mass and body composition in hematological cancer patients during active oncological treatment.
