Effects of an endurance and resistance exercise program on persistent cancer-related fatigue after treatment

Efficacy of ginseng-based Renshenguben oral solution for cancer-related fatigue among patients with advanced-stage hepatocellular carcinoma: A prospective multicenter cohort study

BACKGROUND

Cancer-related fatigue (CRF) is a common and debilitating symptom experienced by patients with advanced-stage cancer, especially those undergoing antitumor therapy. This study aimed to evaluate the efficacy and safety of Renshenguben (RSGB) oral solution, a ginseng-based traditional Chinese medicine, in alleviating CRF in patients with advanced hepatocellular carcinoma (HCC) receiving antitumor treatment.

METHODS

In this prospective, open-label, controlled, multicenter study, patients with advanced HCC at BCLC stage C and a brief fatigue inventory (BFI) score of ≥ 4 were enrolled. Participants were assigned to the RSGB group (RSGB, 10 mL twice daily) or the control group (with supportive care). Primary and secondary endpoints were the change in multidimensional fatigue inventory (MFI) score, and BFI and functional assessment of cancer therapy-hepatobiliary (FACT-Hep) scores at weeks 4 and 8 after enrollment. Adverse events (AEs) and toxicities were assessed.

RESULTS

A total of 409 participants were enrolled, with 206 assigned to the RSGB group. At week 4, there was a trend towards improvement, but the differences were not statistically significant. At week 8, the RSGB group exhibited a significantly lower MFI score (P < 0.05) compared to the control group, indicating improved fatigue levels. Additionally, the RSGB group showed significantly greater decrease in BFI and FACT-Hep scores at week 8 (P < 0.05). Subgroup analyses among patients receiving various antitumor treatments showed similar results. Multivariate linear regression analyses revealed that the RSGB group experienced a significantly substantial decrease in MFI, BFI, and FACT-Hep scores at week 8. No serious drug-related AEs or toxicities were observed.

CONCLUSIONS

RSGB oral solution effectively reduced CRF in patients with advanced HCC undergoing antitumor therapy over an eight-week period, with no discernible toxicities. These findings support the potential of RSGB oral solution as an adjunctive treatment for managing CRF in this patient population.

Effects of a self-managed return to work intervention for colorectal cancer survivors: A prospective randomized controlled trial

PURPOSE

The present study aims to assess the efficacy of stage-matched, self-managed Return to Work (RTW) interventions in enhancing RTW outcomes among colorectal cancer (CRC) survivors.

METHODS

This trial, conducted in South Korea, enrolled 58 unemployed survivors of colorectal cancer. Participants were randomly assigned to either an experimental or a control group. The experimental group received a self-managed return-to-work intervention based on the trans-theoretical model, while the control group received an educational booklet. Assessments were conducted at baseline and at 3, 6, and 12 months to measure changes in various factors including return-to-work status and HRQOL.

RESULTS

In the experimental group, 28 participants were randomly assigned, while 30 individuals were allocated to the control group. The experimental group exhibited a higher proportion of individuals achieving RTW (64.5% vs 39.3%, p = 0.013) and demonstrated greater improvements in work ability (p = 0.001), RTW self-efficacy (p = 0.035), readiness for RTW in the prepared-for-action (p < 00.0001), uncertain maintenance (p = 0.033), and proactive maintenance (p < 00.0001) stages, quality of working life (p = 0.003), HRQOL (p < 0.05), and illness perception (p < 0.05) compared to the control group at the 12-month follow-up.

CONCLUSIONS

Stage-matched self-managed RTW interventions incorporating TTM principles may effectively enhance RTW outcomes and work ability among CRC survivors.

Effectiveness of a dose-graded aerobic exercise regimen on cardiopulmonary fitness and physical performance in pediatric survivors of acute lymphoblastic leukemia: a randomized clinical trial

PURPOSE

To determine whether a 12-week supervised dose-graded aerobic exercise (D-GAE) training, when implemented in conjunction with traditional rehabilitation, could help pediatric survivors of acute lymphoblastic leukemia (ALL) enhance their cardiopulmonary capacity and improve their physical performance.

METHODS

Fifty-eight pediatric survivors of ALL (age 13.78 ± 2.47 years; boys 60.34%) were assigned at random to either undergo the D-GAE in addition to the traditional physical rehabilitation (D-GAE group; n = 29) or the traditional physical rehabilitation solely (control group; n = 29). The cardiopulmonary fitness (peak oxygen uptake (VO2peak), ventilatory equivalent (VEq/VO2), minute ventilation (VE, L/min), oxygen pulse (O2P), maximum heart rate (HRmax), 1-min heart rate recovery (HRR1), and respiratory exchange ratio (RER)) and physical performance (6-min walk test (6-MWT), timed up and down stairs (TUDS), and 4 × 10-m shuttle run test (4 × 10mSRT)) were assessed on the pre- and post-intervention occasions.

RESULTS

The mixed-model ANOVA revealed a meaningful increase of VO2peak (P = .002), VE (P = .026), O2P (P = .0009), HRmax (P = .004), and HRR1 (P = .011), and reduction of VEq/VO2 (P = .003) and RER (P = .003) in the D-GAE group compared with the control group. Besides, the analysis detected a favorable increase in the physical performance for the D-GAE group (6-MWT (P = .007), TUDS (P < .001), 4 × 10mSRT (P = .009)).

CONCLUSION

A 12-week D-GAE program in conjunction with traditional rehabilitation holds promise in enhancing cardiopulmonary fitness and improving the physical performance of pediatric survivors of ALL. Clinicians and physical rehabilitation professionals can, therefore, integrate the D-GAE into the traditional rehabilitation protocols for such a patient population to optimize their cardiopulmonary fitness and physical function, while also facilitating a gradual transition to practice and adaption.

IMPLICATIONS FOR CANCER SURVIVORS

The favorable outcomes of this study bolster the inclusion of D-GAE as a crucial element in the care and rehabilitation of pediatric survivors of ALL. By embracing these findings, healthcare professionals and oncologists can contribute to mitigating the long-term cardiopulmonary and physical complications associated with cancer treatments and fostering a state of enhanced well-being and increased physical activity among survivors.

Effectiveness of exergaming in reducing cancer-related fatigue among children with acute lymphoblastic leukemia: a randomized controlled trial

BACKGROUND

Little is known about the effectiveness of the newly emerging technology of exergaming in reducing Cancer Related Fatigue (CRF).

OBJECTIVES

The study's primary aim was to examine the effectiveness of exergaming in reducing CRF; the secondary aims were to improve functional capacity/endurance and promote physical activity (PA) among children with acute lymphoblastic leukemia (ALL).

METHODS

In this Randomized Controlled Trial (RCT), 45 children aged 6-14 years were randomly assigned into group-I, n = 22, and group II, n = 23. Group-I played exergaming of moderate intensity for 60 min, twice a week for three weeks. Group II was given an instructional session regarding the benefits of PA with advice to practice PA for 60 min twice a week. CRF, functional capacity/endurance, and PA were measured using the pediatric quality of life multidimensional fatigue scale (Ped-QLMFS), six-minute walk test (6-MWT), and Godin-Shepard Leisure Time Physical Activity Questionnaire (QSLTPAQ) respectively. All measurements were taken thrice; in the first, third, and fifth weeks of intervention.

RESULTS

Group-I demonstrated a significant reduction of CRF, and a significant increase of functional capacity/endurance compared to group-II over the five weeks study period. The effect of time × intervention interaction was significant. Based on Cohen's guidelines, CRF and functional capacity/endurance had large effect sizes (η² = 0.41, p = .00) and (η² = 0.27, p = .00) respectively.

CONCLUSION

The protocol of exergaming used in this RCT effectively reduces CRF and promotes functional capacity/endurance and PA in children with ALL undergoing chemotherapy. It may provide an alternative treatment modality to decrease the healthcare load.Key messagesCancer-related fatigue (CRF) is described as physical exhaustion, sleep disturbance, emotional distress, and cognitive dysfunction.Exergaming reduces CRF and promotes functional capacity/endurance and physical activity in children with acute lymphoblastic leukemia undergoing chemotherapy.Exergaming may provide an alternative treatment modality to decrease the healthcare load.

Effect of Exergaming on Quality of Life, Fatigue, and Strength and Endurance Muscle in Cancer Patients: A Randomized Crossover Trial

Objective: To analyze the influence of exergaming (EXE) quality of life, cancer-related fatigue (CRF), electromyography, and strength and endurance muscle in a randomized crossover trial. Methods: We conducted a single-blinded, randomized, and crossover trial, which included 38 cancer volunteers undergoing chemotherapy (Age = 60.07 ± 12.10 years; body mass index = 26.79 ± 5.33 kg/m2). All volunteers were randomized into two intervention moments: EXE and without intervention (WI) and after 1-month washout period of crossing of the evaluated moments. The intervention was performed on an EXE protocol using Xbox 360 Kinect®, with the game "Your Shape Fitness Evolved 2012" two to three times per week for 20 sessions. All volunteers were assessed the CRF and quality-of-life levels through the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire, the median frequency (MDF) by surface electromyography, maximal voluntary isometric contraction (MVIC), and the muscle endurance time at 80% MVIC of the dorsiflexors and plantar flexors using dynamometer. Results: In the comparison between EXE and WI moments, were observed increase in the scores for quality of life (P < 0.001), subscale fatigue (P < 0.001), in the MDF values of right lateral gastrocnemius muscles: P = 0.017, muscle endurance time (left dorsiflexion [LDF]: P < 0.001; right dorsiflexion [RDF]: P < 0.001; left plantar flexion [LPF]: P < 0.001; RPF: P = 0.039), and muscle strength (LDF: P < 0.001; RDF: P < 0.001; LPF: P = 0.002). Conclusion: The crossover study, the EXE protocol promoted improvement in cancer-related fatigue (CRF) and quality of life, increased MVIC, endurance time, and MDF values of the dorsiflexor and plantar flexor muscles of cancer volunteers undergoing chemotherapy.

Exercise interventions for adults with cancer receiving radiation therapy alone

BACKGROUND

Radiation therapy (RT) is given to about half of all people with cancer. RT alone is used to treat various cancers at different stages. Although it is a local treatment, systemic symptoms may occur. Cancer- or treatment-related side effects can lead to a reduction in physical activity, physical performance, and quality of life (QoL). The literature suggests that physical exercise can reduce the risk of various side effects of cancer and cancer treatments, cancer-specific mortality, recurrence of cancer, and all-cause mortality.

OBJECTIVES

To evaluate the benefits and harms of exercise plus standard care compared with standard care alone in adults with cancer receiving RT alone.

SEARCH METHODS

We searched CENTRAL, MEDLINE (Ovid), Embase (Ovid), CINAHL, conference proceedings and trial registries up to 26 October 2022.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that enrolled people who were receiving RT without adjuvant systemic treatment for any type or stage of cancer. We considered any type of exercise intervention, defined as a planned, structured, repetitive, objective-oriented physical activity programme in addition to standard care. We excluded exercise interventions that involved physiotherapy alone, relaxation programmes, and multimodal approaches that combined exercise with other non-standard interventions such as nutritional restriction.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodology and the GRADE approach for assessing the certainty of the evidence. Our primary outcome was fatigue and the secondary outcomes were QoL, physical performance, psychosocial effects, overall survival, return to work, anthropometric measurements, and adverse events.

MAIN RESULTS

Database searching identified 5875 records, of which 430 were duplicates. We excluded 5324 records and the remaining 121 references were assessed for eligibility. We included three two-arm RCTs with 130 participants. Cancer types were breast and prostate cancer. Both treatment groups received the same standard care, but the exercise groups also participated in supervised exercise programmes several times per week while undergoing RT. Exercise interventions included warm-up, treadmill walking (in addition to cycling and stretching and strengthening exercises in one study), and cool-down. In some analysed endpoints (fatigue, physical performance, QoL), there were baseline differences between exercise and control groups. We were unable to pool the results of the different studies owing to substantial clinical heterogeneity. All three studies measured fatigue. Our analyses, presented below, showed that exercise may reduce fatigue (positive SMD values signify less fatigue; low certainty). • Standardised mean difference (SMD) 0.96, 95% confidence interval (CI) 0.27 to 1.64; 37 participants (fatigue measured with Brief Fatigue Inventory (BFI)) • SMD 2.42, 95% CI 1.71 to 3.13; 54 participants (fatigue measured with BFI) • SMD 1.44, 95% CI 0.46 to 2.42; 21 participants (fatigue measured with revised Piper Fatigue Scale) All three studies measured QoL, although one provided insufficient data for analysis. Our analyses, presented below, showed that exercise may have little or no effect on QoL (positive SMD values signify better QoL; low certainty). • SMD 0.40, 95% CI -0.26 to 1.05; 37 participants (QoL measured with Functional Assessment of Cancer Therapy-Prostate) • SMD 0.47, 95% CI -0.40 to 1.34; 21 participants (QoL measured with World Health Organization QoL questionnaire (WHOQOL-BREF)) All three studies measured physical performance. Our analyses of two studies, presented below, showed that exercise may improve physical performance, but we are very unsure about the results (positive SMD values signify better physical performance; very low certainty) • SMD 1.25, 95% CI 0.54 to 1.97; 37 participants (shoulder mobility and pain measured on a visual analogue scale) • SMD⁠⁠⁠⁠⁠⁠ 3.13 (95% CI 2.32 to 3.95; 54 participants (physical performance measured with the six-minute walk test) Our analyses of data from the third study showed that exercise may have little or no effect on physical performance measured with the stand-and-sit test, but we are very unsure about the results (SMD 0.00, 95% CI -0.86 to 0.86, positive SMD values signify better physical performance; 21 participants; very low certainty). Two studies measured psychosocial effects. Our analyses (presented below) showed that exercise may have little or no effect on psychosocial effects, but we are very unsure about the results (positive SMD values signify better psychosocial well-being; very low certainty). • SMD 0.48, 95% CI -0.18 to 1.13; 37 participants (psychosocial effects measured on the WHOQOL-BREF social subscale) • SMD 0.29, 95% CI -0.57 to 1.15; 21 participants (psychosocial effects measured with the Beck Depression Inventory) Two studies recorded adverse events related to the exercise programmes and reported no events. We estimated the certainty of the evidence as very low. No studies reported adverse events unrelated to exercise. No studies reported the other outcomes we intended to analyse (overall survival, anthropometric measurements, return to work).

AUTHORS' CONCLUSIONS

There is little evidence on the effects of exercise interventions in people with cancer who are receiving RT alone. While all included studies reported benefits for the exercise intervention groups in all assessed outcomes, our analyses did not consistently support this evidence. There was low-certainty evidence that exercise improved fatigue in all three studies. Regarding physical performance, our analysis showed very low-certainty evidence of a difference favouring exercise in two studies, and very low-certainty evidence of no difference in one study. We found very low-certainty evidence of little or no difference between the effects of exercise and no exercise on quality of life or psychosocial effects. We downgraded the certainty of the evidence for possible outcome reporting bias, imprecision due to small sample sizes in a small number of studies, and indirectness of outcomes. In summary, exercise may have some beneficial outcomes in people with cancer who are receiving RT alone, but the evidence supporting this statement is of low certainty. There is a need for high-quality research on this topic.

Four-year follow-up on fatigue and sleep quality of a three-armed partly randomized controlled study in breast cancer survivors with cancer-related fatigue

Cancer-related fatigue (CRF) is a frequent long-term symptom in non-metastasized breast cancer patients (BC). This 4-year follow-up intended to compare the long-term effects of a 10-week multimodal therapy (MT: sleep education, psychoeducation, eurythmy- and painting therapy) and combination therapy [CT: MT plus aerobic training (AT)] to AT-control. BC-patients were randomized or allocated by preference to three arms in a comprehensive cohort study. Primary outcome was a composite score including Pittsburgh Sleep Quality Index (PSQI) and Cancer Fatigue Scale (CFS-D), captured at baseline, after 10 weeks of intervention (T1), 6 months later (T2), and after 4 years (T3). We exploratively tested for superiority of MT and CT versus AT after 4 years (T3) based on the statistical model of the main analysis. Of 126 (65 randomized) BC-patients included, 105 started treatments and 79 were re-assessed for long-term effects (T3). MT and CT were superior over AT after 4 years regarding PSQI/CFS-D and PSQI sum-score, respectively (all p < 0.05), but not for CFS-D. The multimodal and combination treatment for breast cancer patients with CRF indicates sustainable long-term superiority over aerobic training for the outcomes sleep quality and combined sleep quality/fatigue. A confirmative randomized controlled trial is warranted.

Systematic Review of Functional Outcomes in Cancer Rehabilitation

OBJECTIVE

To systematically review the evidence regarding rehabilitation interventions targeting optimal physical or cognitive function in adults with a history of cancer and describe the breadth of evidence as well as strengths and limitations across a range of functional domains.

DATA SOURCES

PubMed, Cumulative Index to Nursing and Allied Health Plus, Scopus, Web of Science, and Embase. The time scope was January 2008 to April 2019.

STUDY SELECTION

Prospective, controlled trials including single- and multiarm cohorts investigating rehabilitative interventions for cancer survivors at any point in the continuum of care were included, if studies included a primary functional outcome measure. Secondary data analyses and pilot/feasibility studies were excluded. Full-text review identified 362 studies for inclusion.

DATA EXTRACTION

Extraction was performed by coauthor teams and quality and bias assessed using the American Academy of Neurology (AAN) Classification of Evidence Scheme (class I-IV).

DATA SYNTHESIS

Studies for which the functional primary endpoint achieved significance were categorized into 9 functional areas foundational to cancer rehabilitation: (1) quality of life (109 studies), (2) activities of daily living (61 studies), (3) fatigue (59 studies), (4) functional mobility (55 studies), (5) exercise behavior (37 studies), (6) cognition (20 studies), (7) communication (10 studies), (8) sexual function (6 studies), and (9) return to work (5 studies). Most studies were categorized as class III in quality/bias. Averaging results found within each of the functional domains, 71% of studies reported statistically significant results after cancer rehabilitation intervention(s) for at least 1 functional outcome.

CONCLUSIONS

These findings provide evidence supporting the efficacy of rehabilitative interventions for individuals with a cancer history. The findings should be balanced with the understanding that many studies had moderate risk of bias and/or limitations in study quality by AAN criteria. These results may provide a foundation for future work to establish clinical practice guidelines for rehabilitative interventions across cancer disease types.

Effects of multimodal training program on muscle deoxygenation in women with breast cancer: A randomized controlled trial

Purpose

Chemotherapy and/or radiation are the most often delivered treatments to cancer patients. Usually during the adjuvant treatment, patients complain about fatigue. In addition, physical exercise during adjuvant treatment of cancer seems to have beneficial effects. The aim of this investigation was to assess the effects of multimodal aerobic and strength exercises programs on muscle deoxygenation of patients with breast cancer undergoing adjuvant chemotherapy treatment.

Methods

Thirty-two women with breast cancer (20 patients as the training group and 12 patients as the control group) undergoing adjuvant chemotherapy participated in the study. The training group took part in 6 weeks of supervised intermittent aerobic cycling, home-based walking, isometric and electrical muscle stimulation (EMS) exercise training programs. The Outcome measures were muscle deoxygenation (ΔHHb), Maximal Voluntary isometric Contraction (MViC) and Endurance Time (ET) before and after the training period.

Results

Compared to the control group, a significant increase in ΔHHb (P < 0.01) accompanied with an increase in ET (P < 0.01) and MViC (P < 0.01) of the quadriceps was obtained in the training group. However, no significant differences of MViC, ET and ΔHHb were observed in the control group.

Conclusion

Multimodal aerobic and strength exercise programs enhance muscle oxygen utilization, which may partly explain the improvement in muscular strength and endurance, and the reduction of muscle fatigue in patients with breast cancer during an adjuvant chemotherapy period.

Greek Traditional Dance as a Practice for Managing Stress and Anxiety in Cancer Patients

Stress and anxiety levels in cancer patients tend to decrease by performing bodily-kinesthetic and musical activities. The hypothesis of the present study is that attending lessons in Greek traditional dance is an effective method for managing anxiety and stress in patients diagnosed with cancer of any type both during and after treatment. The study was conducted on 300 cancer patients (150 experimental subjects, 150 controls) selected by Attica hospitals and nonprofit cancer patients' organizations. Each patient in the experimental group attended an 8-week Greek traditional dance lesson program. Lessons were held twice per week, lasting 60 min each. A similar group of cancer patients not participating in any organized physical activity during the same time period served as a control group. Data were collected using the Depression Anxiety Stress Scale 21 (Dass-21) questionnaire and subjected to reliability analysis (Cronbach's alpha) and deviation-dependent analysis (one-way repeated). Both stress and anxiety values decreased significantly in the experimental group (stress value: initial mean = 16.27, second mean = 2.58, final mean = 6.77, p < 0.001; anxiety value: initial mean = 15.59, second mean = 2.81, final mean = 5.35, p < 0.001). In contrast, no significant fluctuation was observed in the control group. Thus, there was a significant decrease in stress and anxiety values in cancer patients who attended Greek traditional dances lessons with important psychotherapeutic significance.

The Clinical Value of Pulmonary Rehabilitation in Reducing Postoperative Complications and Mortality of Lung Cancer Resection: A Systematic Review and Meta-Analysis

Background: Pulmonary rehabilitation is one meaningful way of improving exercise tolerance and pulmonary function. Thus, it may reduce the postoperative complications and mortality of pulmonary resection. Hence, we refreshed the data and conducted this systemic analysis.

Method: We searched Pubmed, Web of Science, and EMBASE using “lung OR pulmonary” AND “operation OR resection OR surgery” AND “rehabilitation or exercise.” The cut-off date was September 30, 2020. The publications were filtrated, and data were extracted from all selected studies by two reviewers. Review Manger 5.1 and the fixed or random regression model were used for calculating the pooled odds ratio (OR).

Result: Finally, 13 publications were enrolled in this study. Among them, five publications reported mortality, nine reported postoperative complications, and seven reported postoperative pulmonary complications. The pooled OR of mortality was 1.32 [95% confidence interval (CI): 0.54–3.23] for the pulmonary rehabilitation group, the pooled OR of postoperative complications was 0.62 (95% CI: 0.49–0.79) for the pulmonary rehabilitation group, and the pooled OR of postoperative pulmonary complications was 0.39 (95% CI: 0.27–0.56) for the pulmonary rehabilitation group. Subgroup analysis revealed the perioperative pulmonary rehabilitation was the most important part.

Conclusion: Pulmonary rehabilitation may not affect the mortality of pulmonary resection patients, however, it could decrease the number of postoperative complications, especially pulmonary complications. Perioperative pulmonary rehabilitation was the most important part of the program.

External application of liver compresses to reduce fatigue in patients with metastatic cancer undergoing radiation therapy, a randomized clinical trial

BACKGROUND

Liver compresses are frequently used in integrative medicine as supportive therapy during cancer treatment in order to reduce fatigue. We performed a pilot study to test whether the external application of yarrow liver compresses impacts fatigue in patients with metastatic cancer undergoing radiation therapy.

METHODS

A randomized prospective pilot trial was performed including patients with brain metastasis or bone metastasis of solid tumors. Patients underwent either palliative radiation therapy (RT) of the metastatic lesions (control group) over two weeks or the same RT with additional external application of yarrow liver compresses once daily during RT. The primary objective was improvement on the general fatigue subscale of the multidimensional fatigue inventory (MFI-20) at the end of treatment, where a mean difference of two points is considered clinically relevant. Secondary objectives included psychological distress, quality of life and qualitative analysis with self-established visual analogue scales (VAS). Mean differences in general fatigue at the end of treatment compared to baseline were analyzed using the ANCOVA test.

RESULTS

From 09/2017 to 08/2019 a total of 39 patients were randomized. Due to drop outs 24 patients (12 per group) were available for analysis. Patients in the intervention group received a mean number of 10.5 (range, 7-14) applications of yarrow liver compresses. The mean improvement at the end of therapy on the general fatigue subscale of the MFI-20 was 2 points in favor of the intervention group (p = 0.13), and all other MFI-20 subscales showed at least a trend towards improvement in favor of the intervention group. Likewise, psychological distress and VAS data was improved, the latter reaching statistical significance for the symptoms fatigue, tension and lack of drive. Major toxicities were not observed.

CONCLUSIONS

External application of liver compresses appears to reduce fatigue within a clinical relevant range in patients with metastatic cancer undergoing radiation therapy.

Multidirectional Walking in Hematopoietic Stem Cell Transplant Patients

BACKGROUND

The effect of a peritransplant multidirectional walking intervention to target losses in physical function and quality of life (QOL) has not been investigated.

PURPOSE

This study examined the effects of a novel multidirectional walking program on physical function and QOL in adults receiving a hematopoietic stem cell transplant (HSCT).

METHODS

Thirty-five adults receiving an autologous or allogeneic HSCT were randomized to a multidirectional walking (WALK) or usual care (CONT) group. The WALK group received supervised training during hospitalization; the CONT group received usual care. Patients were assessed at admission (t0), 3 to 5 d post-HSCT (t1), and 30 d post-HSCT (t2). Physical function measures included the 6-min walk test (6MWT), the Physical Performance Test, and the Timed Up and Go test. Health-related QOL was collected using the Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT) questionnaire.

RESULTS

There were no significant between-group changes for physical function or QOL. However, after the intervention (t1 to t2), the WALK group showed significant improvement in aerobic capacity (6MWT, P = 0.01), physical (P < 0.01) and functional well-being (P = 0.04), and overall QOL scores (P < 0.01). The CONT group saw no significant changes in physical function or QOL. Effect sizes showed the WALK group had a larger positive effect on physical function and QOL. Minimal clinically important differences in the 6MWT and FACT-BMT were exceeded in the WALK group.

CONCLUSION

A multidirectional walking program during the transplant period may be effective at increasing aerobic capacity and QOL for patients receiving HSCT compared with no structured exercise.

An Anecdotal Case Report of Chronic Lymphatic Leukemia with del(11q) Treated with Ibrutinib: Artificial Nourishment and Physical Activity Program

Chronic lymphatic leukemia (CLL) is the most frequent type of leukemia in western countries and when association with del(11q) is correlated with a worse prognosis. We reported the clinical case of an 80-year-old patient with CLL related to del(11q) and a BMI of 16.4 kg/m2, who presented a voluminous mass in abdominal cavity (23 × 14 × 4 cm) which occupied the whole of the mesentery and the retroperitoneal space, treated with ibrutinib, adequate nutrition, and a program of physical activity. He showed a great improvement under ibrutinib therapy and took to artificial nourishment and adequate muscle rehabilitation until he recovered his autonomy. In August 2018, a 5-days-a-week training program was started: Physical activity for at least 20 min consisting of a fast walk in the open air three times a week and a moderate physical activity in the remaining two days of at least 20 consecutive minutes (cycling at a regular pace, carrying light weights). The exercise program included also aerobic, upper and lower limb resistance training, chore stability and stretches. The physical condition further improved and remained excellent throughout the follow-up period. In December 2018, his clinical condition was quite normal; a CT showed a great decrease of all lymphoadenomegaly, and FISH test did not show del(11q). He continued to cultivate his land, while still being treated with ibrutinib. The combination of the right therapy, adequate nutrition, and muscle rehabilitation is the best solution to improve the clinical condition of old cachectic CLL del(11q) patient.

Aerobic capacity attainment and reasons for cardiopulmonary exercise test termination in people with cancer: a descriptive, retrospective analysis from a single laboratory

PURPOSE

Aerobic exercise prescriptions in clinical populations commonly involve target intensities based on cardiopulmonary exercise tests (CPET). CPETs are often discontinued prior to a patient achieving true maximum oxygen consumption (VO₂ max) which can adversely affect exercise dose and efficacy monitoring; however, reasons for early discontinuation are poorly reported. Accordingly, we explored the CPET termination reasons in persons with cancer participating in exercise intervention studies.

METHODS

This study comprised of an exploratory, descriptive analysis of retrospective CPET data (VO₂ and anaerobic threshold) and termination reasons in a convenience sample of people with cancer participating in exercise intervention studies in a single laboratory. CPETs were standardized using the modified Bruce treadmill protocol with expired gas collection and analysis using a metabolic cart. VO₂ max was considered "met" when participants demonstrated (a) oxygen consumption plateau or (b) two of the following criteria: rating of perceived exertion ≥ 9/10, respiratory exchange ratio ≥ 1.15, and/or heart rate of 95% of age-predicted maximum. The frequency and distribution of reasons for test termination relative to the number of CPET exposures for the participants were reported.

RESULTS

Forty-four participants engaged in exercise studies between February 2016 and March 2018 provided data for the analysis. Participants completed up to three CPETs during this period (total of 78 CPETs in the current analysis). Eighty-six percent of all CPETs were terminated prior to achieving VO₂ max verification criteria and no tests resulted in an oxygen consumption plateau. For those that did not demonstrate achievement of VO₂ max verification criteria, reasons for discontinuation were distributed as follows: equipment discomfort-49%, volitional peak-36%, and physical discomfort-14.9%. For those who met VO₂ max criteria, volitional peak was the most common reason for test termination (45.5%), followed by physical discomfort (36.4%), and equipment discomfort (18.2%).

CONCLUSIONS

In our sample of cancer survivors, VO₂ max criteria were infrequently met with equipment discomfort being a primary reason for participant-driven test termination. Protocol and equipment considerations are necessary for interpretation and application of CPET findings in clinical practice.

Effects of Physical Exercise Intervention on Psychological and Physical Fitness in Lymphoma Patients

Background and objectives: Lymphoma patients experience a psychological and physiological decline that could be reversed by exercise. However, little is known about the effects of the exercise on psychological and physical fitness variables. Therefore, the purpose of this longitudinal study was to assess self-efficacy, fatigue and physical fitness before and after an eight-week exercise intervention. Materials and Methods: Thirty-six participants (54.4 ± 19.1 years) performed a supervised exercise program (~60 min, 2d·wk^-1). Each session included a combined progressive training of cardiorespiratory, resistance, flexibility and postural education exercises. Self-efficacy and fatigue were measured with the Regulatory Emotional Self-Efficacy scale and 0-10 rating scale, respectively. Physical fitness was assessed with the body mass index, lower back flexibility, static balance, muscle strength and functional mobility. Results: Adherence to exercise was high (91.2% ± 4.8%) and no major health problems were noted in the patients over the intervention period. At baseline, significant differences were found between Hodgkin's lymphoma and non-Hodgkin's lymphoma patients by age and all dependent measures (p < 0.05). Fatigue significantly decreased and the perceived capability to regulate negative affect and to express positive emotions improved after exercise (p < 0.001). Significant improvements were found for body mass index, trunk lateral flexibility, monopodalic balance, isometric handgrip force and functional mobility (p < 0.001). Fatigue was significantly correlated with handgrip force (r = -0.56, p < 0.001) and functional mobility (r = -0.69, p < 0.001). Conclusions: The supervised exercise program improved psychological and physical fitness without causing adverse effects and health problems. Therefore, exercise to improve fitness levels and reduce perceived fatigue should be considered in the management of lymphoma patients.

Effects of combined supervised intermittent aerobic, muscle strength and home-based walking training programs on cardiorespiratory responses in women with breast cancer

BACKGROUND

The aim of this investigation was to study the effects of supervised combined intermittent aerobic, muscle strength and home-based walking training programs on cardiorespiratory fitness in women with breast cancer during adjuvant chemotherapy treatment.

METHODS

Thirty-two women with breast cancer undertaking adjuvant chemotherapy participated in the study (trained group n=20 and control group n=12). The trained group carried out 6weeks of supervised intermittent cycling aerobic, muscle strength and home-based walking training programs. The self-selected walking speed (WS), walking distance covered (WD), heart rate (rHR), blood lactate ([La]b) concentration and rating of perceived exertion (RPE) were assessed in the two groups during the 6-min walking test before and after the training period.

RESULTS

Compared to controls, a significant increase in the WS (P<0.01) and the WD (P<0.01) accompanied by a significant decrease in resting rHR (P<0.01), exercising HR6' (P<0.01), [La]b (P<0.05), HR6'/WS (P<0.01) and [La]b/WS ratios (P<0.01) was reported in the trained group. However, a significant decrease both in WD (P<0.01) and WS (P<0.01) has been observed in the controls. No significant difference was observed in resting HR, exercising HR6', [La]b, HR6'/WS, and [La]b/WS ratios were observed in the control group. A significant improvement was observed for RPE in training group (P<0.05). However, no difference was shown in controls.

CONCLUSION

Combined training based on intermittent aerobic exercise, muscle strength and walking improve cardiorespiratory responses and reduce the perception of fatigue in women with breast cancer.

Impact of thoracic radiotherapy on respiratory function and exercise capacity in patients with breast cancer

Objective:

To evaluate the impact of thoracic radiotherapy on respiratory function and exercise capacity in patients with breast cancer.

Methods:

Breast cancer patients in whom thoracic radiotherapy was indicated after surgical treatment and chemotherapy were submitted to HRCT, respiratory evaluation, and exercise capacity evaluation before radiotherapy and at three months after treatment completion. Respiratory muscle strength testing, measurement of chest wall mobility, and complete pulmonary function testing were performed for respiratory evaluation; cardiopulmonary exercise testing was performed to evaluate exercise capacity. The total radiotherapy dose was 50.4 Gy (1.8 Gy/fraction) to the breast or chest wall, including supraclavicular lymph nodes (SCLN) or not. Dose-volume histograms were calculated for each patient with special attention to the ipsilateral lung volume receiving 25 Gy (V₂₅), in absolute and relative values, and mean lung dose.

Results:

The study comprised 37 patients. After radiotherapy, significant decreases were observed in respiratory muscle strength, chest wall mobility, exercise capacity, and pulmonary function test results (p < 0.05). DLCO was unchanged. HRCT showed changes related to radiotherapy in 87% of the patients, which was more evident in the patients submitted to SCLN irradiation. V₂₅% significantly correlated with radiation pneumonitis.

Conclusions:

In our sample of patients with breast cancer, thoracic radiotherapy seemed to have caused significant losses in respiratory and exercise capacity, probably due to chest wall restriction; SCLN irradiation represented an additional risk factor for the development of radiation pneumonitis.

Endurance and resistance training in patients with acute leukemia undergoing induction chemotherapy-a randomized pilot study

PURPOSE

Acute leukemia (AL) and its initial treatment can impair physical functioning and capacity significantly. Exercise as a countermeasure has been investigated in few studies confirming its feasibility and safety during intensive induction chemotherapy, but the relative effects of diverse exercise programs have not been analyzed. Therefore, we aimed to investigate independent effects of endurance and resistance training on physical capacity and quality of life (QOL).

METHODS

Twenty-nine adult AL patients were randomly allocated to an endurance (EG), resistance (RG), or control (CG) group. The intervention took place during induction chemotherapy with three exercise sessions per week for 30-45 min each. Endurance capacity at individual anaerobic threshold, maximum knee extension and flexion strength, standardized phase angle (SPA), and QOL were measured at baseline prior to induction chemotherapy and before discharge.

RESULTS

Endurance capacity changed in neither the EG, RG, or CG (P = 0.104); descriptively, the EG (- 0.05 W/kg) and RG (- 0.04 W/kg) exhibited a smaller decrease than CG (- 0.22 W/kg). We noted a significant difference in knee extension strength (P = 0.002); RG improved their maximum strength (+ 0.14 Nm/kg), while the EG's (- 0.13 Nm/kg) and CG's (- 0.19 Nm/kg) was significantly reduced. QOL and SPA revealed no change after the intervention.

CONCLUSIONS

We conclude that resistance training is a key component when exercising during induction chemotherapy: it improved maximum strength, but also influenced endurance capacity even during intensive treatment. Considering the prognostic value of physical function, we strongly propose integrating exercise, especially resistance-based training, already during induction chemotherapy to preserve AL patients' physical capacity and functional status.

Influence of Exergaming on the Perception of Cancer-Related Fatigue

OBJECTIVE

Exercise is recommended for cancer patients to reduce fatigue and improve quality of life. This study's aim is to evaluate the influence of an exergaming protocol on cancer-related fatigue, muscle fatigue, and muscle strength in cancer patients.

MATERIALS AND METHODS

We conducted a quasi-experimental control study using exergaming in all groups through an Xbox360 Kinect™ console, two to three times per week, for 20 sessions. Three groups were created: cancer patients in chemotherapy and/or radiotherapy group (CRG; n:15), cancer patients after chemotherapy and/or radiotherapy (CAG; n:15), and a control group (CG; n:15). They were assessed for cancer-related fatigue using the fatigue subscale of the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire. To assess dorsiflexor and plantar flexor muscle functioning, we used median frequency (MDF) of the surface electromyography and muscle strength using a dynamometer. The assessments were performed preintervention (EV0), after 10 sessions (EV1), and after 20 sessions (EV2).

RESULTS

With an exergaming protocol, CRG and CAG showed a reduction in related fatigue compared with CG (P < 0.01). The CRG group saw an increase in maximal voluntary isometric contraction in right plantar flexor muscles and dorsiflexor muscles, as well as an increase in the MDF of both medial gastrocnemius muscles and the left tibialis anterior muscle of the CAG. For other analyses done, the differences were observed during exergaming.

CONCLUSIONS

Exergaming demonstrated efficacy in reducing cancer patients' fatigue, including muscle fatigue, and increasing muscle strength in patients' legs.

Physical activity for women with breast cancer after adjuvant therapy

BACKGROUND

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

OBJECTIVES

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

SEARCH METHODS

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

SELECTION CRITERIA

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

DATA COLLECTION AND ANALYSIS

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

MAIN RESULTS

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

AUTHORS' CONCLUSIONS

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

Subjective cognitive impairment and brain structural networks in Chinese gynaecological cancer survivors compared with age-matched controls: a cross-sectional study

Background

Subjective cognitive impairment can be a significant and prevalent problem for gynaecological cancer survivors. The aims of this study were to assess subjective cognitive functioning in gynaecological cancer survivors after primary cancer treatment, and to investigate the impact of cancer treatment on brain structural networks and its association with subjective cognitive impairment.

Methods

This was a cross-sectional survey using a self-reported questionnaire by the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) to assess subjective cognitive functioning, and applying DTI (diffusion tensor imaging) and graph theoretical analyses to investigate brain structural networks after primary cancer treatment.

Results

A total of 158 patients with gynaecological cancer (mean age, 45.86 years) and 130 age-matched non-cancer controls (mean age, 44.55 years) were assessed. Patients reported significantly greater subjective cognitive functioning on the FACT-Cog total score and two subscales of perceived cognitive impairment and perceived cognitive ability (all p values <0.001). Compared with patients who had received surgery only and non-cancer controls, patients treated with chemotherapy indicated the most altered global brain structural networks, especially in one of properties of small-worldness (p = 0.004). Reduced small-worldness was significantly associated with a lower FACT-Cog total score (r = 0.412, p = 0.024). Increased characteristic path length was also significantly associated with more subjective cognitive impairment (r = −0.388, p = 0.034).

Conclusion

When compared with non-cancer controls, a considerable proportion of gynaecological cancer survivors may exhibit subjective cognitive impairment. This study provides the first evidence of brain structural network alteration in gynaecological cancer patients at post-treatment, and offers novel insights regarding the possible neurobiological mechanism of cancer-related cognitive impairment (CRCI) in gynaecological cancer patients. As primary cancer treatment can result in a more random organisation of structural brain networks, this may reduce brain functional specificity and segregation, and have implications for cognitive impairment. Future prospective and longitudinal studies are needed to build upon the study findings in order to assess potentially relevant clinical and psychosocial variables and brain network measures, so as to more accurately understand the specific risk factors related to subjective cognitive impairment in the gynaecological cancer population. Such knowledge could inform the development of appropriate treatment and rehabilitation efforts to ameliorate cognitive impairment in gynaecological cancer survivors.

Cancer-Related Fatigue in Cancer Survivorship

Cancer-related fatigue (CRF) significantly interferes with usual functioning because of the distressing sense of physical, emotional, and cognitive exhaustion. Assessment of CRF is important and should be performed during the initial cancer diagnosis, throughout cancer treatment, and after treatment using a fatigue scoring scale (mild-severe). The general approach to CRF management applies to cancer survivors at all fatigue levels and includes education, counseling, and other strategies. Nonpharmacologic interventions include psychosocial interventions, exercise, yoga, physically based therapy, dietary management, and sleep therapy. Pharmacologic interventions include psychostimulants. Antidepressants may also benefit when CRF is accompanied by depression.

Muscle wasting as main evidence of energy impairment in cancer cachexia: future therapeutic approaches

The present review aimed at discussing the impact, pathogenesis and therapeutic approaches of muscle wasting, which is a major clinical feature of cancer-related cachexia syndrome. The pathogenesis of muscle wasting in cancer cachexia lies in a discrepancy between anabolic and catabolic pathways mediated by chronic inflammation. Effective interventions specifically aimed at hampering muscle loss and enhancing muscle function are still lacking. Promising agents include anti-inflammatory, orexigenic and anabolic drugs, alongside with nutritional supplements that influence the STAT3 and PI3K/Akt/mTOR pathways involved in muscle wasting. Personalized physical activity combined with pharmacological and nutritional support hold promise. A greater understanding of the pathogenetic processes of cancer cachexia-related muscle wasting will enable the development of an early and effective targeted mechanism-based multimodal approach.

Physical function and quality of life in patients with chronic GvHD: a summary of preclinical and clinical studies and a call for exercise intervention trials in patients

Allogeneic hematopoietic stem cell transplant, to reconstitute the hematopoietic and immune status of patients undergoing myeloablative therapy for hematologic disorders, has been of great benefit in minimizing or eradicating disease and extending survival. Patients who undergo allogeneic hematopoietic stem cell transplant (allo-HSCT) are subject to many comorbidities among which the most significant, affecting quality of life (QoL) and survival, are acute GvHD (aGvHD) and chronic GvHD (cGvHD), resulting from donor lymphocytes reacting to and damaging host tissues. Physical activity and exercise have clearly been shown, in both children and adults, to enhance fitness, improve symptomatology and QoL, reduce disease progression and extend survival for many diseases including malignancies. In some cases, vigorous exercise has been shown to be equal to or more effective than pharmacologic therapy. This review addresses how cGvHD affects patients' physical function and physical domain of QoL, and the potential benefits of exercise interventions along with recommendations for relevant research and evaluation targeted at incorporating this strategy as soon as possible after allo-HSCT and ideally, as soon as possible upon diagnosis of the condition leading to allo-HSCT.

Ongoing Screening and Treatment to Potentially Reduce Tyrosine Kinase Inhibitor-Related Fatigue in Renal Cell Carcinoma

CONTEXT

Renal cell carcinoma (RCC) represents 1% to 4% of adult malignancies, and approximately 33% of patients with RCC present with metastatic disease and have a poor prognosis. Better understanding of RCC tumor biology has led to the development of several molecularly targeted agents, such as tyrosine kinase inhibitors (TKIs), to manage advanced disease. Although evolving data suggest these drugs may be beneficial in RCC, they are associated with significant toxicities. Cancer-related fatigue (CRF) is one of the most common toxicities associated with the TKIs used in RCC.

OBJECTIVES

To review the incidence, pathophysiology, and management of CRF in patients with RCC who are undergoing targeted therapy with TKIs.

METHODS

A comprehensive database search was performed using PubMed, Ovid, Embase, and MEDLINE. References of all cited articles also were reviewed. Data from articles published between 1975 and June 2014 were considered. A narrative review regarding the incidence, pathophysiology, and management of CRF in patients with RCC undergoing targeted therapy with TKIs was performed.

RESULTS

CRF is one of the most common TKI toxicities in patients with metastatic RCC and often is the dose-limiting toxicity. Management of TKI-related CRF can be difficult and may necessitate various nonpharmacologic and pharmacologic interventions.

CONCLUSION

TKI-related CRF in patients with RCC is a highly distressing complication of cancer therapy. CRF can substantially influence drug compliance, the ability to maximally treat, and quality of life. It is important to recognize this common, yet frequently underdiagnosed complication and initiate appropriate management strategies, to increase the likelihood for optimal outcomes.

Clinical characteristics of patients with cancer referred for outpatient physical therapy

BACKGROUND

Cancer rehabilitation is a developing area, with an increasing number of survivors of cancer in the United States. The increase in survivorship occurs alongside impairments arising directly from cancer or from treatment-related side effects.

OBJECTIVE

This study described clinical characteristics of patients with cancer referred for outpatient physical therapy and explored patterns in frequency of impairments between type of cancer and mode of cancer treatment.

DESIGN

This was a retrospective chart review of patients with cancer referred to a tertiary care physical therapy clinic over a 2-year period.

METHODS

Characteristics such as age, sex, cancer type, mode of treatment, and neuromusculoskeletal impairments were identified. Impairment frequencies were computed based on cancer type and mode of treatment.

RESULTS

Data from 418 patients (mean age=57.9 years, SD=14.3; 41.1% female) were examined. Genitourinary cancer (n=169) and breast cancer (n=90) were the most prevalent types of cancer reported in this sample. Impairments in strength (83.6%) and soft tissue (71.3%) were the most common examination findings. Lymphedema was most common in patients with breast cancer, and incontinence was most common in patients with genitourinary cancer.

LIMITATIONS

The types of cancer identified in this study may be reflective of this tertiary center and may not generalize to other facilities. Impairment identification during the initial physical therapist evaluation was not performed systematically.

CONCLUSION

These data reinforce that physical therapists should screen for lymphedema in patients with breast cancer and incontinence in urogenital cancers. Strength and soft tissue integrity should be evaluated in most patients with cancer. Assessing pain and fatigue levels is recommended for patients who have had radiation therapy.

Exercise compliance among patients with multiple myeloma undergoing chemotherapy: a retrospective study

PURPOSE

Multiple myeloma (MM) is often associated with osteolytic bone disease and anemia, resulting in skeletal fragility and persistent fatigue, pain, and reduced quality of life. Exercise is considered safe and beneficial for this population. Our objectives were to evaluate the extent to which MM patients undergoing chemotherapy complied with exercise recommendations and to identify factors associated with noncompliance.

METHODS

This retrospective study included 41 MM patients referred to a hospital-based rehabilitation program while undergoing chemotherapy. Variables collected at baseline (T1) and follow-up (T2) included: (a) demographics and medical history, (b) exercise levels (MET-hours/week), preferences and barriers, and (c) fatigue severity scores (0-10). Statistical analyses included logistic regression to identify factors associated with exercise noncompliance and t-tests and chi-squared tests to compare outcomes between the groups according to compliance.

RESULTS

The mean age of the participants was 61 years; 73 % were male and 81 % had bone lesions. Overall exercise compliance at T2 was 71 %, with an observed increase in exercise levels (mean group difference: 6.5 MET-hours/week; p < 0.001) and decrease in fatigue severity scores (mean group difference -1.2; p = 0.003). Factors associated with exercise noncompliance included history of pathological fracture (odds ratio [OR] 4.7; p = 0.049), spinal cord compression (SCC) (OR 14.1; p = 0.023), and radiation (OR 28.0; p < 0.001).

CONCLUSIONS

In this sample of MM patients, high compliance with exercise and associated improvements in fatigue were observed. However, participants with a history of pathological fracture, SCC, or radiation are at increased risk of noncompliance and may require additional supervision to improve exercise compliance.

Do we have predictors of therapy responsiveness for a multimodal therapy concept and aerobic training in breast cancer survivors with chronic cancer-related fatigue?

Cancer-related fatigue (CRF) is a burdensome symptom for breast cancer (BC) patients. In this pilot study, we tested several questionnaires as predictors for treatment responsiveness, along with the implementation of a multimodal therapy concept consisting of sleep, psycho-education, eurythmy, painting therapy and standard aerobic training. At the Community Hospital Havelhöhe and the Hannover Medical School, 31 BC patients suffering from CRF could be evaluated in a 10-week intervention study. CRF was assessed by the Cancer Fatigue Scale (CFS-D). Further questionnaires were the Pittsburgh Sleep Quality Index, the autonomic regulation scale, Self-Regulation Scale (SRS), the Internal Coherence Scale (ICS) and the European Organization of Research and Treatment Health-Related Quality of Life Core Questionnaire scale. We estimated the regression coefficients of all scales on CFS-D by simple and multiple linear regression analyses and compared regression slopes and variances between the different questionnaires on CFS-D at the end of treatment. We found a significant impact of SRS and ICS at baseline on CFS-D at the end of the intervention [absolute standardised multiple regression coefficient values ranging from 0.319 (SRS) to 0.269 (ICS)] but not for the other questionnaires. In conclusion, this study supports the hypothesis that the SRS or ICS measuring adaptive capacities could be more appropriate as outcome predictors than classical questionnaire measures in complex interventions studies.

Cancer Type Does Not Affect Exercise-Mediated Improvements in Cardiorespiratory Function and Fatigue

Purpose. Despite mounting evidence indicating that exercise training has a positive effect on cancer recovery, the influence of cancer type on the response to exercise training remains uncharacterized. Therefore, the adaptations to exercise training were compared between groups composed of 7 different forms of cancer. Methods. A total of 319 cancer survivors completed fatigue inventories and participated in assessments of cardiorespiratory function, which encompassed aerobic capacity (VO2peak), pulmonary function (forced vital capacity [FVC] and forced expiratory volume in 1 second [FEV1]), and resting blood pressure and heart rate. Participants were divided into 7 groups based on cancer type, including breast cancer (BC, n = 170), prostate cancer and other male urogenital neoplasia (PC, n = 38), hematological malignancies (HM, n = 34), colorectal cancer (CC, n = 25), gynecological cancers (GC, n = 20), glandular and epithelial neoplasms (GEN, n = 20), and lung cancer (LC, n = 12). All participants completed an individualized, multimodal exercise intervention consisting of cardiorespiratory, flexibility, balance, and muscular strength training 3 days per week for 3 months. Following the intervention, all subjects were reassessed. Generalized Estimating Equations with exchangeable working correlation structure was used to model each response; the group by time interaction effect represented the effect of cancer type on exercise-associated improvements. Results. No significant ( P > .05) group by time interaction effects were observed between different types of cancer for any parameter. Pre- to postexercise contrasts revealed significant improvements in VO2peak in BC, PC, HM, and GEN at the Bonferroni adjusted significance level (.00714). Heart rate was significantly lowered in the BC and CC groups. Mean fatigue indices decreased by at least 17% in all groups, but these changes were only significant in the BC, HM, CC, and GC groups. Systolic blood pressure decreased significantly in BC and GC, and diastolic blood pressure decreased significantly only in the BC group while pulmonary function remained unchanged in all cancer types. Conclusion. Although trends toward improved cardiorespiratory and fatigue parameters only reached significance in some groups, there were no significant differences between cancer types. This suggests that cardiorespiratory and fatigue improvements following rehabilitative exercise are not dependent on cancer type. Further research investigating alternative physiological parameters are needed to confirm the relationship between cancer type and exercise-mediated rehabilitation.

Pulmonary rehabilitation for respiratory disorders other than chronic obstructive pulmonary disease

Pulmonary rehabilitation (PR) is an important therapeutic intervention that should no longer be considered suitable only for patients with chronic obstructive pulmonary disease (COPD). A strong rationale exists for providing PR to persons with a broad range of respiratory disorders other than COPD. Evidence shows that PR for these patients is feasible, safe and effective. A disease-relevant approach should be undertaken, based on individual patients' needs. Further research is needed to better understand the optimal program content, duration and outcomes measures, to enable diverse patients to achieve maximal benefits of PR.

Quality of life and fatigue of patients with spinal bone metastases under combined treatment with resistance training and radiation therapy- a randomized pilot trial

BACKGROUND

The aim of this trial was to compare the effects of resistance training versus passive physical therapy on quality of life (QoL), fatigue, and emotional distress outcomes during radiation therapy in patients with spinal bone metastases under radiotherapy (RT).

METHODS

In this randomized trial, 60 patients were treated from September 2011 until March 2013 into one of the two groups: isometric resistance training or physical therapy with thirty patients in each group during RT. EORTC QLQ-BM22, EORTC QLQ-FA13, and FBK-R10 were assessed at baseline, three months, and six months after RT.

RESULTS

Psychosocial aspects in resistance training group (Arm A) were significantly improved after three (p = 0.001) and six months (p = 0.010). Other rated items of the QLQ-BM22 painful site, and pain characteristics were without significant differences. Functional interference showed a positive trend after six months (p = 0.081). After six months, physical fatigue (p = 0.013), and interference with daily life (p = 0.006) according to the QLQ-FA13 assessment improved in Arm A significantly. Emotional distress was in Arm A lower after six months (p = 0.016). The Cohen's effect size confirmed the clinically significant improvement of these findings.

CONCLUSIONS

In this group of patients we were able to show that guided isometric resistance training of the paravertebral muscles can improve functional capacity, reduce fatigue and thereby enhance QoL over a 6-months period in patients with stable spinal metastases. The results offer a rationale for future large controlled investigations to confirm these findings.

Fatigue after liver transplantation: effects of a rehabilitation program including exercise training and physical activity counseling

BACKGROUND

It is hypothesized that increasing physical fitness and daily physical activity can lead to a reduction in fatigue. However, standard medical care following liver transplantation seldom includes rehabilitation that focuses on physical fitness and physical activity.

OBJECTIVE

The aim of this study was to explore whether a rehabilitation program can reduce fatigue in recipients of liver transplants. Furthermore, effects on physical fitness, physical activity, and cardiovascular risk were studied, and adherence, satisfaction, and adverse events were assessed.

DESIGN

This was an uncontrolled intervention study.

SETTING

The study took place in an outpatient rehabilitation clinic.

PATIENTS

Eighteen recipients of a liver transplant who were fatigued participated in a 12-week rehabilitation program including physical exercise training and counseling on physical activity. The primary outcome measure was fatigue. Other outcome measures were: aerobic capacity, muscle strength, body fat, daily physical activity, lipid profile, and glycemic control. All measurements were performed before and after the rehabilitation program. Adherence, satisfaction, and adverse events were registered.

RESULTS

After the program, participants were significantly less fatigued, and the percentage of individuals with severe fatigue was 22% to 53% lower than before the program. In addition, aerobic capacity and knee flexion strength were significantly higher, and body fat was significantly lower after the program. Participants were able to perform physical exercise at the target training intensity, no adverse events were registered, and attendance (93%) and mean patient satisfaction (8.5 out of 10, range=7-10) were high.

LIMITATIONS

No control group was used in the study.

CONCLUSIONS

A rehabilitation program consisting of exercise training and physical activity counseling is well tolerated and seems promising in reducing fatigue and improving fitness among recipients of liver transplants.

Pulmonary rehabilitation. Sociedad Española de Neumología y Cirugía Torácica (SEPAR)

Pulmonary rehabilitation (PR) has been shown to improve dyspnea, exercise capacity and health-related quality of life in patients with chronic obstructive pulmonary disease (COPD). PR has also shown benefits in diseases other than COPD but the level of evidence is lower. The fundamental components of PR programs are muscle training, education and chest physiotherapy. Occupational therapy, psychosocial support and nutritional intervention should also be considered. Home programs have been shown to be as effective as hospital therapy. The duration of rehabilitation programs should not be less than 8 weeks or 20 sessions. Early initiation of PR, even during exacerbations, has proven safe and effective. The use of oxygen or noninvasive ventilation during training is controversial and dependent on the patient's situation. At present, the best strategy for maintaining the benefits of PR in the long term is unknown. Longer PR programs or telemedicine could play a key role in extending the results obtained.

Effect of dance on cancer-related fatigue and quality of life

PURPOSE

Cancer-related fatigue is a multidimensional symptom with an underestimated prevalence and severity in cancer patients. The aim of the study was to evaluate the effect of dance as a holistic sportive activity in cancer patients under active anticancer treatment with fatigue as endpoint.

PATIENTS AND METHODS

Forty patients under active anticancer treatment (adjuvant (25), palliative (11) or neoadjuvant (4)) with moderate or severe fatigue (≥ 4 on the visual analogue scale) were investigated in two groups for severity of fatigue (visual analogue scale, Functional Assessment of Chronic Illness Therapy: Fatigue questionnaire), quality of life (European Organization for Research and Treatment of Cancer, Quality of Life Questionnaire) and physical performance (6-minute walk test) before and after the study period--group A (n = 20): intervention (10 dance classes in 5 weeks in addition to counselling) and group B (n = 20): control (no dance, standard of care, counselling).

RESULTS

We found significant improvements for cancer-related fatigue in the intervention group (baseline mean ± SD 5.95 ± 1.701, end-of-study mean 3.8 ± 1.542, p = 0.001, reduction of 36 %) compared to the control group (baseline mean 4.95 ± 0.999, end-of-study mean unchanged at 5.0 ± 1.556, p = 0.887); as well as for emotional and social functioning scales and physical performance (p < 0.05).

CONCLUSION

Dance might be an appropriate, effective approach for treatment of cancer-related fatigue.

Can a multimodal mind-body program enhance the treatment effects of physical activity in breast cancer survivors with chronic tumor-associated fatigue? A randomized controlled trial

Background. Chronic fatigue is one of the most restricting symptoms following primary breast cancer treatment, but clinical studies on symptom management are rare. The objective was to evaluate the impact of a multimodal mind-body program (MMMT), including moderate physical activity as compared with a walking intervention alone, on chronic fatigue symptoms of women with stage I to IIIA breast cancer.

PATIENTS AND METHODS

Sixty-four women (mean age = 56.7 years) suffering from chronic fatigue after active tumor treatment were randomly assigned to either an experimental or a control (n = 32 each) intervention (10 weeks). Fatigue, quality of life (QoL), functional well-being, anxiety, and depression were measured with standard questionnaires at baseline, after 10 weeks, and after 3 months.

RESULTS

Compared with baseline, both groups had reduced fatigue scores after treatment without any significant difference between groups (posttreatment, Δ = -0.3, confidence interval = -1.6 to 1.0, P = .678; follow-up, Δ = -0.4, confidence interval = -1.8 to 0.9, P = .510). All patients also improved regarding QoL and general functional well-being.

CONCLUSION

Since both interventions reduced fatigue symptoms and enhanced QoL to a similar extent, we observed no verifiable add-on effect of the MMMT regarding fatigue symptoms. Considering the higher costs with additional expenditure related to MMMT, home-based walking intervention is recommended.

Impact of autonomic and self-regulation on cancer-related fatigue and distress in breast cancer patients--a prospective observational study

PURPOSE

Cancer-related fatigue (CRF) has a major impact on the quality of life in breast cancer patients (BC). So far, only a few prospective studies have investigated the effect of adaptive salutogenic mechanisms on CRF. The aim of our study was to evaluate the possible prospective influence of autonomic Regulation (aR) and self-regulation (SR) on CRF and distress in long-term survivors.

METHODS

95 BC and 80 healthy female controls (C) had been included in the observational study between 2000 and 2001 and completed the questionnaires on aR, SR and Hospital Anxiety and Depression Scale (HADS). Of these, 62 BC, and 58 C participated in the re-evaluation 6.6 years later: 16 participants were deceased (14 BC and 2 C). During follow-up, participants were requested to answer questions involving (Cancer Fatigue Scales) CFS-D, aR, SR and HADS. Multiple regression analysis was used to evaluate the influence of aR, SR, age, Charlson co-morbidity-index and diagnosis on CFS-D and HADS, and to select further potentially relevant factors.

RESULTS

High aR values showed significant effects, namely inverse relationships with CFS-D, cognitive fatigue, anxiety and depression. SR showed a reduced influence on anxiety and depression (all p < 0.05).

CONCLUSIONS

Autonomic regulation might have an independent, reductive influence on global fatigue, cognitive fatigue and--together with self-regulation--it seems to have a protective influence on anxiety and depression. The connection between these parameters is still unclear and awaits further evaluation.

IMPLICATION FOR CANCER SURVIVORS

AR seems to be a prognostic factor in breast cancer survivors, capable of reducing cancer-related fatigue and self-regulation distress as well. Further research is necessary in order to show how aR can be improved by therapeutic interventions.

Effects of exercise on angiogenesis and apoptosis-related molecules, quality of life, fatigue and depression in breast cancer patients

The aim of this study was to explore the effects of exercise on angiogenesis and apoptosis-related molecules, quality of life, fatigue and depression in patients who completed breast cancer treatment. Sixty breast cancer patients were randomised into three groups, as supervised exercise group, home exercise group and education group. Angiogenesis and apoptosis-related cytokine levels and quality of life (EORTC QOL-C30: European Organisation for Research and Treatment of Cancer Quality of Life C30), fatigue (Brief Fatigue Inventory) and depression (BDI: Beck Depression Inventory) scores were compared before and after a 12-week exercise programme. After the exercise programme, statistically significant decreases were found in interleukin-8 and neutrophil activating protein-78 levels in the home exercise group (P < 0.05). The education group showed a statistically significant increase in monocyte chemoattractant protein-1 level (P < 0.05). Functional score and global health score of EORTC QOL-C30 in the supervised exercise group and functional score of EORTC QOL-C30 in the home exercise group increased significantly after exercise programme (P < 0.05). BDI score was significantly lower in the supervised exercise group after the exercise programme (P < 0.05). Changes in angiogenesis and apoptosis-related molecules in the study groups suggest a possible effect of exercise on these parameters. Exercise programmes are safe and effective on quality of life and depression in breast cancer patients whose treatments are complete.

Exercise for fatigue management in hematopoietic stem cell transplantation recipients

Fatigue is a commonly reported symptom of patients who have undergone hematopoietic stem cell transplantation (HSCT). Fatigue in the HSCT recipient has multiple possible causes, including deconditioning, anemia, and medications. Regardless of the cause, fatigue impacts patients' well-being, ability to reintegrate into their normal lifestyle, physical recovery from transplantation, and overall symptom management. The authors discuss the current evidence regarding exercise for the management of fatigue in this population and lay the groundwork for developing an evidence-based intervention.

The role and efficacy of exercise in persons with cancer

Improvements in cancer screening, diagnosis, and treatment have resulted in an increasing population of cancer survivors with impairments in physical function, cancer-related symptoms, and reduced quality of life. Exercise and physical activity have therapeutic value at multiple points along the cancer disease continuum, spanning disease prevention, treatment, survivorship, prognostic outcomes, and end-of-life issues. Molecular mechanisms for the influence of exercise in persons with cancer include altering tumor initiation pathways and affecting hormonal, inflammatory, immune, and insulin pathways. Physical activity has been found to play a role in the prevention of certain malignancies, including breast, colon, and other cancers. An increasing amount of evidence indicates that physical activity may affect prognostic outcomes in certain cancer diagnoses, especially breast cancer. Structured exercise and physical activity interventions can be helpful in addressing specific survivorship issues, including overall quality of life, cardiorespiratory impairment, cancer-related fatigue, and lymphedema. Exercise also may be helpful during the palliative care phase to alleviate symptoms and increase physical well-being. This article will familiarize physiatrists with the current state of evidence regarding the role and efficacy of exercise in persons with cancer.

A pilot study of an exercise & cognitive behavioral therapy intervention for epithelial ovarian cancer patients

BACKGROUND

Ovarian cancer has the highest mortality rate of all gynaecologic cancers. Faced with poor prognoses, stressful treatment effects and a high likelihood of recurrence, survivors must confront significant physical and psychological morbidities that negatively impact health-related quality of life. Frequently reported side effects include cancer-related fatigue, peripheral neuropathy, and psychological distress. Exercise and cognitive behavioral therapy interventions have counteracted such adverse effects in other cancer populations.

OBJECTIVE

To investigate the feasibility and benefits of a 24-week home-based exercise intervention, coordinated with 12 weeks of cognitive behavioral therapy (two sessions per month), developed for two types of patients diagnosed with epithelial ovarian cancer: 1) those undergoing primary treatment with adjuvant chemotherapy after primary surgery; 2) those on surveillance after completing treatment within the last 2 years.

METHODS

Participants were recruited from the Gynaecologic Oncology Clinic. Eligible participants completed baseline assessments and were provided with home-based exercise equipment. Cognitive behavioral therapy was provided every other week for patients via telephone. Assessments were completed at baseline (T1), 3 months (T2) and 6 months (T3).

RESULTS

19 of the 46 eligible patients approached were enrolled, with 7 patients in the treatment group and 12 in the surveillance group. There was a significant within group increase in peak VO2 from baseline to 6 months: F(2,16) = 5.531, p = 0.015, partial η2 = 0.409.

CONCLUSION

The combined 6-month exercise-cognitive behavioral therapy intervention was associated with significant increases in aerobic fitness in epithelial ovarian cancer patients assessed. These improvements were similar regardless of whether the patient was receiving chemotherapy or under surveillance.

Effects of exercise on fatigue, sleep, and performance: a randomized trial

PURPOSE/OBJECTIVES

To compare usual care with a home-based individualized exercise program (HBIEP) in patients receiving intensive treatment for multiple myeloma (MM)and epoetin alfa therapy.

DESIGN

Randomized trial with repeated measures of two groups (one experimental and one control) and an approximate 15-week experimental period.

SETTING

Outpatient setting of the Myeloma Institute for Research and Therapy at the Rockfellow Cancer Center at the University of Arkansas for Medical Sciences.

SAMPLE

187 patients with newly diagnosed MM enrolled in a separate study evaluating effectiveness of the Total Therapy regimen, with or without thalidomide.

METHODS

Measurements included the Profile of Mood States fatigue scale, Functional Assessment of Cancer Therapy-Fatigue, ActiGraph® recordings, 6-Minute Walk Test, and hemoglobin levels at baseline and before and after stem cell collection. Descriptive statistics were used to compare demographics and treatment effects, and repeated measures analysis of variance was used to determine effects of HBIEP.

MAIN RESEARCH VARIABLES

Fatigue, nighttime sleep, performance (aerobic capacity) as dependent or outcome measures, and HBIEP combining strength building and aerobic exercise as the independent variable.

FINDINGS

Both groups were equivalent for age, gender, race, receipt of thalidomide, hemoglobin levels, and type of treatment regimen for MM. No statistically significant differences existed among the experimental and control groups for fatigue, sleep, or performance (aerobic capacity). Statistically significant differences (p < 0.05) were found in each of the study outcomes for all patients as treatment progressed and patients experienced more fatigue and poorer nighttime sleep and performance (aerobic capacity).

CONCLUSIONS

The effect of exercise seemed to be minimal on decreasing fatigue, improving sleep, and improving performance (aerobic capacity).

IMPLICATIONS FOR NURSING

Exercise is safe and has physiologic benefits for patients undergoing MM treatment; exercise combined with epoetin alfa helped alleviate anemia.
