Short-Term Changes in Quality of Life in Patients with Advanced Lung Cancer during In-Hospital Exercise Training and Chemotherapy Treatment: A Randomized Controlled Trial

Comparative effects of different types of exercise on health-related quality of life during and after active cancer treatment: A systematic review and network meta-analysis

BACKGROUND

The positive influence of most types of exercise has been reported repeatedly, but what the most effective exercise approaches are for improving health-related quality of life (HRQoL) in people with cancer remains unknown. The aim of this systematic review and network meta-analysis was to synthesize the evidence from intervention studies to assess the effects of different types of exercise on HRQoL during and after cancer treatment.

METHODS

MEDLINE, SPORTDiscus, the Cochrane Library, Web of Science, and Scopus were searched for randomized controlled trials aimed at testing the effects of exercise interventions meant to improve HRQoL in people with cancer. Separate analyses were conducted for HRQoL as measured by general and cancer-specific questionnaires. We also evaluated whether the effects of exercise were different during and after cancer treatment in both the physical and mental HRQoL domains.

RESULTS

In total, 93 studies involving 7435 people with cancer were included. Network effect size estimates comparing exercise intervention vs. usual care were significant for combined exercise (0.35, 95% confidence interval (95%CI): 0.14-0.56) for HRQoL as measured by general questionnaires, and for combined (0.31, 95%CI: 0.13-0.48), mind-body exercise (0.54, 95%CI: 0.18-0.89), and walking (0.39, 95%CI: 0.04-0.74) for HRQoL as measured by cancer-specific questionnaires.

CONCLUSION

Exercise programs combining aerobic and resistance training can be recommended to improve HRQoL during and after cancer treatment. The scarcity and heterogeneity of these studies prevents us from making recommendations about other exercise modalities due to insufficient evidence.

The Effect of Exercise on Pain in People with Cancer: A Systematic Review with Meta-analysis

INTRODUCTION

Cancer-related pain is common and undertreated. Exercise is known to have a pain-relieving effect in non-cancer pain.

OBJECTIVES

This systematic review aimed to evaluate (1) the effect of exercise on cancer-related pain in all cancers, and (2) whether the effect of exercise differed according to exercise mode, degree of supervision, intervention duration and timing (during or after cancer treatment), pain types, measurement tool and cancer type.

METHODS

Electronic searches were undertaken in six databases to identify exercise studies evaluating pain in people with cancer, published prior to 11 January 2023. All stages of screening and data extraction were conducted independently by two authors. The Cochrane risk of bias tool for randomised trials (RoB 2) was used and overall strength of evidence was assessed using the GRADE approach. Meta-analyses were performed overall and by study design, exercise intervention and pain characteristics.

RESULTS

In total, 71 studies reported in 74 papers were eligible for inclusion. The overall meta-analysis included 5877 participants and showed reductions in pain favouring exercise (standardised mean difference - 0.45; 95% confidence interval - 0.62, - 0.28). For most (> 82%) of the subgroup analyses, the direction of effect favoured exercise compared with usual care, with effect sizes ranging from small to large (median effect size - 0.35; range - 0.03 to - 1.17). The overall strength of evidence for the effect of exercise on cancer-related pain was very low.

CONCLUSION

The findings provide support that exercise participation does not worsen cancer-related pain and that it may be beneficial. Better pain categorisation and inclusion of more diverse cancer populations in future research would improve understanding of the extent of benefit and to whom.

Effect of Exercise Training on Quality of Life, Symptoms, and Functional Status in Advanced-Stage Lung Cancer Patients: A Systematic Review

Advanced-stage lung cancer (LC) causes significant morbidity and impacts patients' quality of life (QoL). Exercise has been proven to be safe, feasible, and beneficial for symptom reduction and QoL improvement in many types of cancers, but research is limited in advanced-stage LC patients. This systematic review evaluates the effect of exercise interventions on the symptoms and QoL in patients with advanced-stage LC. Twelve prospective studies (744 participants) were included, evaluating different combinations of exercises and training such as aerobics, tai chi, strength, inspiratory muscle training, and relaxation. Studies found outcomes including but not limited to improved QoL, symptom burden, psychosocial health, functional status, and physical function. The results of this review support that exercise is safe and feasible with evidence supporting improved QoL and symptom mitigation. Integration of exercise should be considered in the individualized management of advanced-stage LC patients under the guidance of their healthcare providers.

[Physical activity and lung cancer: A synthesis of the literature]

INTRODUCTION

Physical activity (PA) has its place in the continuum of care, the objective being to limit alterations associated with cancer and its treatments. This review of the literature collates the evidence and current data relating to PA carried out at different periods of treatment for lung cancer.

STATE OF THE ART

PA is safe and feasible in patients with lung cancer throughout their oncologic treatment. The efficacy of multimodal programs is demonstrated regarding symptoms, exercise capacity, functional capacity, postoperative complications, length of hospital stay and quality of life. Nevertheless, this result remains to be confirmed with more robust upcoming trial, notably in the long term.

PERSPECTIVES

Utilization of activity and energy expenditure sensors or PA questionnaires could help to increase the PA level of lung cancer patients during their continuum of care. For those not at ease with conventional training modalities, it may be judicious to offer intermittent high-intensity training or respiratory muscle strength training. Telerehabilitation could also be implemented. The targeting of populations at high risk should be investigated.

CONCLUSION

Teams caring for patients with lung cancer during or after their oncologic treatment should develop innovative strategies designed to overcome difficulties of access or adherence to exercise programs, so that the PA be an integral part of the care of these patients. Physical therapists play an important role in supporting these patients during their assessment or treatment.

Adaptation and multicentre validation of a patient-centred outcome scale for people severely ill with COVID (IPOS-COV)

BACKGROUND

Patient-centred measures to capture symptoms and concerns have rarely been reported in severe COVID. We adapted and tested the measurement properties of the proxy version of the Integrated Palliative care Outcome Scale-IPOS-COV for severe COVID using psychometric approach.

METHODS

We consulted experts and followed consensus-based standards for the selection of health status measurement instruments and United States Food and Drug Administration guidance for adaptation and analysis. Exploratory Factor Analysis and clinical perspective informed subscales. We tested the internal consistency reliability, calculated item total correlations, examined re-test reliability in stable patients, and also evaluated inter-rater reproducibility. We examined convergent and divergent validity of IPOS-COV with the Australia-modified Karnofsky Performance Scale and evaluated known-groups validity. Ability to detect change was examined.

RESULTS

In the adaptation phase, 6 new items were added, 7 items were removed from the original measure. The recall period was revised to be the last 12-24 h to capture fast deterioration in COVID. General format and response options of the original Integrated Palliative care Outcome Scale were preserved. Data from 572 patients with COVID from across England and Wales seen by palliative care services were included. Four subscales were supported by the 4-factor solution explaining 53.5% of total variance. Breathlessness-Agitation and Gastro-intestinal subscales demonstrated good reliability with high to moderate (a = 0.70 and a = 0.67) internal consistency, and item-total correlations (0.62-0.21). All except the Flu subscale discriminated well between patients with differing disease severity. Inter-rater reliability was fair with ICC of 0.40 (0.3-0.5, 95% CI, n = 324). Correlations between the subscales and AKPS as predicted were weak (r = 0.13-0.26) but significant (p < 0.01). Breathlessness-Agitation and Drowsiness-Delirium subscales demonstrated good divergent validity. Patients with low oxygen saturation had higher mean Breathlessness-Agitation scores (M = 5.3) than those with normal levels (M = 3.4), t = 6.4 (186), p < 0.001. Change in Drowsiness-Delirium subscale correctly classified patients who died.

CONCLUSIONS

IPOS-COV is the first patient-centred measure adapted for severe COVID to support timely management. Future studies could further evaluate its responsiveness and clinical utility with clinimetric approaches.

Effect of exercise interventions in adults with cancer receiving palliative care: a systematic review and meta-analysis

PURPOSE

Previous publications showed the effectiveness of exercise in adults with cancer receiving palliative care, but evidence for palliative care research on exercise is lacking. The purpose is to examine the effects of an exercise intervention on exercise capacity, physical function, and patient-reported outcome measures in adults with cancer receiving palliative care.

METHODS

We searched databases including EMBASE, PubMed, and Web of Science from inception until 2021. We used the Cochrane criteria to assess the risk of bias within studies. Using RevMan, mean difference (MD) and 95% confidence intervals or standardized mean difference (SMD) and 95% confidence intervals were calculated.

RESULTS

A total of 14 studies and 1034 adults with cancer receiving palliative care are included in this systematic review and meta-analysis. Half of the studies were deemed to have high risk of bias. All of the interventions used aerobic and/or resistance exercises. The results indicated that exercise interventions significantly improved exercise capacity (mean difference: 46.89; 95% confidence interval: 4.51 to 89.26; Z = 2.17; P = 0.03), pain (standardized mean difference: - 0.29; 95% confidence interval: - 0.54 to - 0.03; Z = 2.18; P = 0.03), fatigue (standardized mean difference: - 0.48; 95% confidence interval: - 0.83 to - 0.12; Z = 2.66; P = 0.008), and quality of life (standardized mean difference: 0.23; 95% confidence interval: 0.02 to 0.43; Z = 2.12; P = 0.03).

CONCLUSION

Exercise training, with aerobic exercise, resistance exercise, or combined aerobic and resistance exercise, helps to maintain or improve exercise capacity, pain, fatigue, and quality of life in adults with cancer receiving palliative care.

Virtual reality in chemotherapy support for the treatment of physical functions, fear, and quality of life in pediatric cancer patients: A systematic review and meta-analysis

Background

Appropriately selected complementary therapies, such as virtual reality (VR) and active video games (AVG), provide support to young patients during the process of cancer treatment. Therefore, this systematic review with meta-analysis aimed to analyze the effects of VR and AVG on fear, physical functions, and quality of life.

Methods

A systematic search was performed independently in Scopus, PubMed, Embase, Web of Science and Cochrane Library electronic databases for relevant randomized controlled and crossover studies. From a total of 5,963 records, 11 met the inclusion criteria. After full-text screening two publications were excluded, yet six studies were included in the quantitative analysis because three studies had a large discrepancy in their measured outcomes. For methodological quality assessments, the RoB2 software program was used, while RevMan 5.4.1 was used for statistical analysis and meta-analysis. Standard Mean Difference (SMD) outcome measures were used for the analysis. Statistical heterogeneity was assessed using the I2 statistic with a cut-off value of 50% considering intervention and outcome measures.

Results

Our systematic review includes six randomized controlled studies and three randomized crossover studies. The participants represented both sexes and were children and adolescents (<18 years old) with a diagnosis of cancer. The analysis of the results allows for a careful conclusion that VR has the potential to become an accessory tool in rehabilitation and oncologic treatment. All of the included studies noted a significant advantage of this intervention.

Conclusion

VR has the potential to be an effective and important tool in the oncologic treatment of children. VR immerses the patient, and as a result, produces a distraction that effectively reduces pain associated with standard oncologic care procedures in children. However, this systematic review and meta-analysis highlights the need for more research into the use of VR as support for pediatric oncologic care.

Virtual reality as a chemotherapy support in treatment of anxiety and fatigue in patients with cancer: A systematic review and meta-analysis and future research directions

OBJECTIVE

The aim of this systematic review was to analyse the effectiveness of virtual reality intervention as an aid for treatment-related anxiety and fatigue in cancer patients undergoing chemotherapy. The term chemotherapy was assumed without distinction regarding type.

METHODS

The inclusion criteria were (1) randomised controlled trials or crossover studies, (2) adult cancer patients undergoing chemotherapy, (3) treatment with VR scenarios providing distraction during chemotherapy, and (4) with pain, anxiety, fatigue, fear, or symptom distress as the measured outcomes. Articles in English, Polish, and Italian were sought. For the methodological quality assessment of risk of bias, likewise statistical analysis and meta-analysis the RevMan version 5.4 software and the Cochrane Risk of Bias Tool were used. Two authors independently analysed the following databases for relevant research articles: PubMed, Scopus, Cochrane Library, Web of Science, and Embase.

RESULTS

From a total of 2543 records, 6 studies met the inclusion criteria for qualitative analysis. At the end of the process, 3 studies remained for quantitative analysis. The systematic review includes three randomised, controlled studies and three crossover studies with an overall sample size of 453 patients. The analysis of the primary outcomes chosen for each study revealed no significant differences between the control and experimental conditions. Moreover, an important factor influencing the results of the review and meta-analysis was the poor quality of the publications available on the topic of distraction during chemotherapy.

CONCLUSION

Due to the low research standards, the results do not provide an unambiguous answer to the research question. The most important limitations result from the small number of trials, the generally small sample sizes, and the differences in study design.
