Functional and postoperative outcomes after preoperative exercise training in patients with lung cancer: a systematic review and meta-analysis

The Physical Activity and Cancer Control (PACC) framework: update on the evidence, guidelines, and future research priorities

BACKGROUND

We proposed the Physical Activity and Cancer Control (PACC) framework in 2007 to help organise, focus, and stimulate research on physical activity in eight cancer control categories: prevention, detection, treatment preparation/coping, treatment coping/effectiveness, recovery/rehabilitation, disease prevention/health promotion, palliation, and survival.

METHODS

This perspective paper provides a high-level overview of the scientific advances in physical activity research across cancer control categories, summarises current guidelines, updates the PACC framework, identifies remaining and emerging knowledge gaps, and provides future research directions.

RESULTS

Many scientific advances have been made that are reflected in updated physical activity guidelines for six of the cancer control categories apart from detection and palliation. Nevertheless, the minimal and optimal type, dose, and timing of physical activity across cancer control categories remain unknown, especially for the understudied population subgroups defined by cancer type, age, race/ethnicity, and resource level of regions/countries.

CONCLUSION

To achieve the full benefit of physical activity in cancer control, future research should use innovative study designs that include diverse at-risk populations and understudied cancer sites. Additionally, effective behaviour change strategies are needed to increase physical activity levels across populations that use implementation science to accelerate the translation from evidence generation into practical, real-world interventions.

Relationship between prehabilitation responsiveness and postoperative physical functional recovery in cardiovascular surgery

BACKGROUND

The purpose of this study was to examine the relationship between responsiveness to prehabilitation and postoperative recovery of physical function in cardiac surgery patients.

METHODS

Ninety-three cardiac surgery patients (mean age: 76.4 years) were included in this retrospective cohort study. Preoperative physical function was measured using the Short Physical Performance Battery (SPPB), and a prehabilitation exercise program was implemented for the SPPB domains with low scores. Among the patients, those whose SPPB score was over 11 from the start of prehabilitation and remained over 11 on the day before surgery were defined as the high-functioning group, and those whose SPPB score improved by 2 points or more from the start of prehabilitation and exceeded 11 points were defined as the responder group. Those whose SPPB score did not exceed 11 immediately before surgery were classified as non-responders. The characteristics of each group and postoperative recovery of physical function were investigated.

RESULTS

There were no serious adverse events during prehabilitation. Mean days of prehabilitation was 5.4 days. The responder group showed faster improvement in postoperative physical function and shorter time to ambulatory independence than the non-responder group. The non-responder group had lower preoperative skeletal muscle index, more severe preoperative New York Heart Association classification, and a history of musculoskeletal disease or stroke.

CONCLUSION

There were responders and non-responders to prehabilitation among cardiac surgery patients. Cardiac surgery patients who respond to prehabilitation had faster recovery of physical function. Further research is needed to determine what type of prehabilitation is more effective in postoperative recovery of physical function in cardiac surgery patients.

Relevance of Cardiovascular Exercise in Cancer and Cancer Therapy-Related Cardiac Dysfunction

PURPOSE OF THE REVIEW

Cancer therapy-related cardiac dysfunction (CTRCD) has been identified as a threat to overall and cancer-related survival. Although aerobic exercise training (AET) has been shown to improve cardiorespiratory fitness (CRF), the relationship between specific exercise regimens and cancer survival, heart failure development, and reduction of CTRCD is unclear. In this review, we discuss the impact of AET on molecular pathways and the current literature of sports in the field of cardio-oncology.

RECENT FINDINGS

Cardio-oncological exercise trials have focused on variations of AET intensity by using moderate continuous and high intensity interval training, which are applicable, safe, and effective approaches to improve CRF. AET increases CRF, reduces cardiovascular morbidity and heart failure hospitalization and should thus be implemented as an adjunct to standard cancer therapy, although its long-term effect on CTRCD remains unknown. Despite modulating diverse molecular pathways, it remains unknown which exercise regimen, including variations of AET duration and frequency, is most suited to facilitate peripheral and central adaptations to exercise and improve survival in cancer patients.

Early Ambulation Following Lung Resection Surgery: Impact on Short-term Outcomes in Patients with Lung Cancer

OBJECTIVES

Previous studies indicated that early ambulation following lung resection can prevent postoperative pulmonary complications (PPCs). However, some patients fail to achieve early ambulation owing to factors such as postoperative nausea, vomiting, or pain, particularly on postoperative day 1. This study aimed to address the critical clinical question: Is ambulation for ≥10 m during initial pulmonary rehabilitation necessary after lung resection surgery?

METHODS

This retrospective observational cohort study included 407 patients who underwent lung resection surgery for lung cancer between January 2021 and December 2022. Twelve patients with a performance status of ≥2 and 21 patients lacking pulmonary rehabilitation prescriptions were excluded. Patients were categorized into the "early ambulation" group, which included individuals ambulating ≥10 m during rehabilitation on the first postoperative day, and the "delayed ambulation" group. The primary outcome was PPC incidence, with secondary outcomes encompassing pleural drain duration, hospital length of stay, and Δ6-minute walk distance (Δ6MWD: postoperative 6MWD minus preoperative 6MWD).

RESULTS

The early and delayed ambulation groups comprised 315 and 59 patients, respectively. Significant disparities were noted in the length of hospital stay (7 [6-9] days vs. 8 [6-11] days, P = 0.01), pleural drainage duration (4 [3-5] days vs. 4 [3-6] days, P = 0.02), and Δ6MWD (-70 m vs. -100 m, P = 0.04). However, no significant difference was observed in PPC incidence (20.6% vs. 32.2%, P = 0.06).

CONCLUSIONS

Ambulation for ≥10 m during initial pulmonary rehabilitation after lung resection surgery may yield short-term benefits as evidenced by improvements in various outcomes. However, it may not significantly affect the PPC incidence.

Physical activity for cancer prehabilitation: A scoping review

This scoping review aims to synthesize the current landscape of physical activity in cancer prehabilitation and identify knowledge gaps. We searched MEDLINE, EMBASE, SCOPUS and WEB OF SCIENCE for exercise interventions and observational studies that measured exercise or physical activity before cancer treatment from inception to January 20, 2023. Fifty-one articles from 44 unique studies were reviewed, including 32 intervention and 12 observational studies. Surgery is the only treatment modality that has been investigated. Included studies used heterogeneous exercise interventions and measures for physical activity. Colorectal and other gastrointestinal, lung, and urologic cancers are the most studied cancer types. Exercise intervention in cancer prehabilitation is highly feasible. The evidence for improved fitness, functional, psychosocial, and clinical outcomes is promising yet limited. Although research has increased recently, prehabilitation exercise remains a relatively under-investigated area in oncology. We have provided research directions towards an ideal cancer prehabilitation design in the real-world setting.

Exercise, cancer, and the cardiovascular system: clinical effects and mechanistic insights

Cardiovascular diseases and cancer are the leading causes of death in the Western world and share common risk factors. Reduced cardiorespiratory fitness (CRF) is a major determinant of cardiovascular morbidity and cancer survival. In this review we discuss cancer- induced disturbances of parenchymal, cellular, and mitochondrial function, which limit CRF and may be antagonized and attenuated through exercise training. We show the impact of CRF on cancer survival and its attenuating effects on cardiotoxicity of cancer-related treatment. Tailored exercise programs are not yet available for each tumor entity as several trials were performed in heterogeneous populations without adequate cardiopulmonary exercise testing (CPET) prior to exercise prescription and with a wide variation of exercise modalities. There is emerging evidence that exercise may be a crucial pillar in cancer treatment and a tool to mitigate cardiotoxic treatment effects. We discuss modalities of aerobic exercise and resistance training and their potential to improve CRF in cancer patients and provide an example of a periodization model for exercise training in cancer.

Chinese Herbal Medicine Combined With Liuzijue Exercise in Physiological Rehabilitation After Video-assisted Lung Lobectomy for Cancer: A Prospective Propensity Score Matching Study

OBJECTIVE

To observe the clinical efficacy of Chinese herbal medicine combined with Liuzijue exercise on the physiological symptoms and quality of life (QoL) in postoperative patients with early-stage lung cancer.

METHODS

One hundred and eighty-three lung cancer patients who underwent video-assisted thoracoscopic surgery (VATS) were categorize into either a traditional Chinese medicine treatment group (CM) or a control group (non-traditional Chinese medicine treatment, NC), among whom 73 underwent Chinese herbal medicine and Liuzijue therapy, while 110 underwent no comprehensive treatment with traditional Chinese medicine. The propensity score matching (PSM) method with a 1:2 ratio was used to balance the baseline characteristics and evaluate the efficacy of CM in improving postoperative symptoms and QoL.

RESULTS

Cough, dyspnea, chest pain, and fatigue were the most common clinical symptoms after VATS. Except for chest pain, they were all correlated with the scope of operation (P < .05). After PSM, 165 patients were identified in the matched cohort, and the covariates of gender, age, operative site, and scope of operation were balanced between the 2 groups (P > .05). In the domain of global health status, the improvement in QoL in CM was greater than that in NC (6.06 ± 15.83 vs -1.06 ± 14.68, P = .005). In terms of symptoms, improvements in cough (1.69 ± 3.15 vs 0.38 ± 2.63, P = .006), dyspnea during climbing stairs (-10.30 ± 16.82 vs -1.82 ± 17.97, P = .004), and pain (-0.76 ± 1.32 vs -0.08 ± 1.31, P = .002) in CM were better than in NC.

CONCLUSION

Comprehensive treatment with traditional Chinese medicine (TCM) can provide therapeutic benefits in physiological rehabilitation after VATS for cancer.

Epigenetic and inflammatory markers in older adults with cancer: A Young International Society of Geriatric Oncology narrative review

The number of adults aged ≥ 65 years with cancer is rapidly increasing. Older adults with cancer are susceptible to treatment-related acute and chronic adverse events, resulting in loss of independence, reduction in physical function, and decreased quality of life. Nevertheless, evidence-based interventions to prevent or treat acute and chronic adverse events in older adults with cancer are limited. Several promising blood-based biomarkers related to inflammation and epigenetic modifications are available to identify older adults with cancer who are at increased risk of accelerated aging and physical, functional, and cognitive impairments caused by the cancer and its treatment. Inflammatory changes and epigenetic modifications can be reversible and targeted by lifestyle changes and interventions. Here we discuss ways in which changes in inflammatory and epigenetic pathways influence the aging process and how these pathways can be targeted by interventions aimed at reducing inflammation and aging-associated biological markers. As the number of older adults with cancer entering survivorship continues to increase, it is becoming progressively more important to understand ways in which the benefit from treatment can be enhanced while reducing the effects of accelerated aging.

Prehabilitation programs for individuals with cancer: a systematic review of randomized-controlled trials

BACKGROUND

Prehabilitation programs focusing on exercise training as the main component are known as a promising alternative for improving patients' outcomes before cancer surgery. This systematic review determined the benefits and harms of prehabilitation programs compared with usual care for individuals with cancer.

METHODS

We searched CENTRAL, MEDLINE, and EMBASE from inception to June 2022, and hand searched clinical trial registries. We included randomized-controlled trials (RCTs) in adults, survivors of any type of cancer, that compared prehabilitation programs that had exercise training as the major component with usual care or other active interventions. Outcome measures were health-related quality of life (HRQL), muscular strength, postoperative complications, average length of stay (ALOS), handgrip strength, and physical activity levels. Two reviewers independently screened the studies, extracted data, and assessed the risk of bias and the certainty of the evidence.

RESULTS

Twenty-five RCTs (2682 participants) published between 2010 and 2022 met our inclusion criteria. Colorectal and lung cancers were the most common diagnoses. The studies had methodological concerns regarding outcome measurement, selective reporting, and attrition. Five prehabilitation programs were compared to usual care (rehabilitation): combined training, aerobic training, respiratory muscle training plus aerobic training, respiratory muscle training plus resistance training, and pelvic floor training. The studies provided no clear evidence of an effect between groups. We assessed the overall certainty of the evidence as very low, downgraded due to serious study limitations and imprecision.

CONCLUSION

Prehabilitation programs focusing on exercise training may have an effect on adults with cancer, but the evidence is very uncertain. We have very little confidence in the results and the true effect is likely to be substantially different from these. Further research is needed before we can draw a more certain conclusion.

A qualitative stakeholder analysis of beliefs, facilitators, and barriers for a feasible prehabilitation program before lung cancer surgery

BACKGROUND

In order to develop a feasible prehabilitation program before surgery of NSCLC, this study aimed to gain insight into beliefs, facilitators, and barriers of (1) healthcare professionals to refer patients to a prehabilitation program, (2) patients to participate in and adhere to a prehabilitation program, and (3) informal caregivers to support their loved ones.

METHODS

Semi-structured interviews were conducted with healthcare professionals, patients who underwent surgery for NSCLC, and their informal caregivers. The capability, opportunity, and motivation for behavior-model (COM-B) guided the development of the interview questions. Results were analyzed thematically.

RESULTS

The interviews were conducted with twelve healthcare professionals, seventeen patients, and sixteen informal caregivers. Four main themes were identified: (1) content of prehabilitation and referral, (2) organizational factors, (3) personal factors for participation, and (4) environmental factors. Healthcare professionals mentioned that multiple professionals should facilitate the referral of patients to prehabilitation within primary and secondary healthcare involved in prehabilitation, considering the short preoperative period. Patients did not know that a better preoperative physical fitness and nutritional status would make a difference in the risk of postoperative complications. Patients indicated that they want to receive information about the aim and possibilities of prehabilitation. Most patients preferred a group-based physical exercise training program organized in their living context in primary care. Informal caregivers could support their loved one when prehabilitation takes place by doing exercises together.

CONCLUSION

A prehabilitation program should be started as soon as possible after the diagnosis of lung cancer. Receiving information about the purpose and effects of prehabilitation in a consult with a physician seems crucial to patients and informal caregivers to be involved in prehabilitation. Support of loved ones in the patient's own living context is essential for adherence to a prehabilitation program.

The Use of Fissios App© as a Complement to a Face-to-Face Respiratory Physiotherapy Program versus an Attendance-Only Face-to-Face Physiotherapy Program in Patients Scheduled for Thoracic Surgical Procedures Reduces the Risk of Developing Postoperative Pulmonary Complications-A Quasi-Experimental Study

Postoperative pulmonary complications (PPCs) increase the hospital length of stay (LOS) and the cost of healthcare associated with surgical procedures. Strategies to reduce PPCs begin before surgery and continue in the postoperative period. Fissios App© is a smartphone application that contains perioperative medical advice and a structured respiratory physiotherapy program. The objective was to implement the use of this app in a group of patients scheduled for a thoracic surgical procedure and determine its efficacy in reducing PPCs. This was a quasi-experimental study in which all patients attended a face-to-face respiratory physiotherapy program, and the intervention group used Fissios App© as a complement. We prospectively recorded the postoperative evolution of both groups, analyzed the categorical differences and quantitative variables, and created a binary logistic regression model. We recruited 393 patients (131 intervention and 262 control). The intervention group had a lower incidence of PPCs (12.2% versus 24% in the control group, p = 0.006), a shorter LOS (a median of 3 days (IQR = 2-5) versus 4 days (IQR = 3-6, p = 0.001) in the control group), and a reduction in the risk of developing PPCs by 63.5% (OR: 0.365, 95% CI: 0.17-0.78). The use of Fissios App© improved the clinical outcomes after surgery and reduced the probability of developing PPCs.

Incorporating Exercise Training into Cardio-Oncology Care: Current Evidence and Opportunities: JACC: CardioOncology State-of-the-Art Review

Cancer treatment-induced cardiotoxicities are an ongoing concern throughout the cancer care continuum from treatment initiation to survivorship. Several "standard-of-care" primary, secondary, and tertiary prevention strategies are available to prevent the development or further progression of cancer treatment-induced cardiotoxicities and their risk factors. Despite exercise's established benefits on the cardiovascular system, it has not been widely adopted as a nonpharmacologic cardioprotective strategy within cardio-oncology care. In this state-of-the-art review, the authors discuss cancer treatment-induced cardiotoxicities, review the existing evidence supporting the role of exercise in preventing and managing these sequelae in at-risk and affected individuals living after cancer diagnoses, and propose considerations for implementing exercise-based services in cardio-oncology practice.

Effects of exercise prehabilitation and/or rehabilitation on health-related quality of life and fatigue in patients with non-small cell lung cancer undergoing surgery: A systematic review

BACKGROUND

This systematic review aimed to appraise the current available evidence regarding the effects of exercise prehabilitation and rehabilitation on perceived health-related quality of life (HRQoL) and fatigue in patients undergoing surgery for non-small cell lung cancer (NSCLC).

METHODS

Studies were selected according to Cochrane guidelines and assessed for methodological quality and therapeutic quality (the international CONsensus on Therapeutic Exercise aNd Training (i-CONTENT)). Eligible studies included patients with NSCLC performing exercise prehabilitation and/or rehabilitation and postoperative HRQoL and fatigue up to 90-days postoperatively.

RESULTS

Thirteen studies were included. Exercise prehabilitation and rehabilitation significantly improved postoperative HRQoL in almost half of the studies (47%), although none of the studies demonstrated a decrease in fatigue. Methodological quality and therapeutic quality were poor in respectively 62% and 69% of the studies.

CONCLUSION

There was an inconsistent effect of exercise prehabilitation and exercise rehabilitation on improving HRQoL in patients with NSCLC undergoing surgery, with no effect on fatigue. Due to the low methodological and therapeutic quality of included studies, it was not possible to identify the most effective training program content to improve HRQoL and reduce fatigue. It is recommended to investigate the impact of a high therapeutic qualified exercise prehabilitation and exercise rehabilitation on HRQoL and fatigue in larger studies.

Prehabilitation in Patients With Breast Cancer Receiving Neoadjuvant Therapy to Minimize Musculoskeletal Postoperative Complications and Enhance Recovery (PREOPtimize): A Protocol for a Randomized Controlled Trial

OBJECTIVE

The aim of this study is to assess the effects of a prehabilitation program (PREOPtimize), consisting of Nordic Walking and resistance training exercises plus health education among patients with breast cancer, who are receiving neoadjuvant therapy to enhance postoperative functionality of the affected arm. A secondary aim will be to compare the short-term effects of the intervention on other patient-reported outcome measures.

METHODS

This will be an assessor-blind, randomized controlled trial with a parallel group design conducted at a tertiary hospital. A sample of 64 patients with breast cancer scheduled for surgery and undergoing neoadjuvant chemotherapy will be recruited for the trial and randomly allocated to either (1) a prehabilitation program consisting of 2 weekly sessions of 75 minutes of Nordic Walking, muscle strengthening exercises, and health education sessions conducted between the fourth month of treatment and surgery or (2) usual care. Patients in both groups will be assessed at baseline, before surgery, and at 1 and 3 months after surgery. Assessed outcomes include functionality of the affected arm (QuickDash), arm volume, range of motion, handgrip strength, pain, fatigue, functional capacity, physical activity levels, and health-related quality of life. Adherence to the intervention in the prehabilitation group and adverse events will also be recorded.

IMPACT

Prehabilitation for patients affected by breast cancer is rarely implemented in clinical practice. The results obtained with the PREOPtimize trial could show that prehabilitation is a feasible intervention for patients with breast cancer receiving neoadjuvant therapy that might enhance postoperative recovery of upper arm function as well as improve overall physical performance and health-related quality of life.

Implementing a virtual mind-body prehabilitation program for patients undergoing thoracic surgery: A quality improvement project

Background

Prehabilitation before thoracic surgery has been found to improve outcomes in patients with cancer; however, COVID-19 presented challenges to access on-site programs. We describe the development, implementation, and evaluation of a synchronous, virtual mind-body prehabilitation program developed in response to COVID-19.

Methods

Eligible participants were patients seen at a thoracic oncology surgical department of an academic cancer center, aged 18 years or older with a diagnosis of thoracic cancer and referred at least 1 week before surgery. The program offered 2 45-minute preoperative mind-body fitness classes each week delivered via Zoom (Zoom Video Communications, Inc). We collected data for referrals, enrollment, participation, and evaluated patient-reported satisfaction and experience. We conducted brief semistructured interviews about participants' experience.

Results

Among 278 patients referred, 260 were approached, and of those 197 (76%) patients agreed to participate. Among participants, 140 (71%) attended at least 1 class, with an average of 11 attendees per class. The majority of participants reported being extremely satisfied (97.8%), extremely likely to recommend the classes to others (91.2%), and indicated that classes were very much helpful in preparing for surgery (90.8%). Patients also reported that the classes helped reduce anxiety/stress (94.2%), fatigue (88.5%), pain (80.7%), and shortness of breath (86.5%). Qualitative data further suggest that the program made participants feel stronger, more connected to their peers, and better prepared for surgery.

Conclusions

This virtual mind-body prehabilitation program was well received with high satisfaction and benefits and is highly feasible to implement. This approach may help overcome some of the challenges to in-person participation.

Association of Preoperative High-Intensity Interval Training With Cardiorespiratory Fitness and Postoperative Outcomes Among Adults Undergoing Major Surgery: A Systematic Review and Meta-Analysis

Importance

Preoperative high-intensity interval training (HIIT) is associated with improved cardiorespiratory fitness (CRF) and may improve surgical outcomes.

Objective

To summarize data from studies comparing the association of preoperative HIIT vs standard hospital care with preoperative CRF and postoperative outcomes.

Data Sources

Data sources included Medline, Embase, Cochrane Central Register of Controlled Trials Library, and Scopus databases with no language constraints, including abstracts and articles published before May 2023.

Study Selection

The databases were searched for randomized clinical trials and prospective cohort studies with HIIT protocols in adult patients undergoing major surgery. Thirty-four of 589 screened studies met initial selection criteria.

Data Extraction and Synthesis

A meta-analysis was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Data were extracted by multiple independent observers and pooled in a random-effects model.

Main Outcomes and Measures

The primary outcome was change in CRF, as measured by either peak oxygen consumption (V̇o2 peak) or 6-Minute Walk Test (6MWT) distance. Secondary outcomes included postoperative complications; hospital length of stay (LOS); and changes in quality of life, anaerobic threshold, and peak power output.

Results

Twelve eligible studies including 832 patients were identified. Pooled results indicated several positive associations for HIIT when compared with standard care either on CRF (V̇o2 peak, 6MWT, anaerobic threshold, or peak power output) or postoperative outcomes (complications, LOS, quality of life), although there was significant heterogeneity in study results. In 8 studies including 627 patients, there was moderate-quality evidence of significant improvement in V̇o2 peak (cumulative mean difference, 2.59 mL/kg/min; 95% CI, 1.52-3.65 mL/kg/min; P < .001). In 8 studies including 770 patients, there was moderate-quality evidence of a significant reduction in complications (odds ratio, 0.44; 95% CI, 0.32-0.60; P < .001). There was no evidence that HIIT differed from standard care in hospital LOS (cumulative mean difference, -3.06 days; 95% CI, -6.41 to 0.29 days; P = .07). The analysis showed a high degree of heterogeneity in study outcomes and an overall low risk of bias.

Conclusions and Relevance

The results of this meta-analysis suggest that preoperative HIIT may be beneficial for surgical populations through the improvement of exercise capacity and reduced postoperative complications. These findings support including HIIT in prehabilitation programs before major surgery. The high degree of heterogeneity in both exercise protocols and study results supports the need for further prospective, well-designed studies.

Implementation of a perioperative care App in elective thoracic surgery

INTRODUCTION

The design and implementation inconsistency of perioperative care programs limits their universalization, and it is where e-Health can standardize these processes. The objective of the study is to create a Smartphone App with a perioperative care program, implement it in a group of patients scheduled for a thoracic surgical procedure, and evaluates its use.

METHODS

A prospective and descriptive study. We created a Smartphone app (Fissios App) which contains 40 perioperative recommendations and 10 chest physical exercises. Patients were recommended to use it before and after surgery; to measure its use, we created and applied a questionnaire. A descriptive analysis of patient variables and questionnaire responses was performed and their association evaluated.

RESULTS

One hundred four patients were included, 60.3% were men with a median age of 62 years (51-71), and 26.72% had completed high school. The 89.3% of patients highlighted the ease of downloading and setting up the app. More than 90% of patients positively assessed clarity in explaining chest physical exercises and perioperative recommendations. One hundred four (79.4%) patients highlighted the contribution of the use of the app during the preoperative period to face the postoperative period.

CONCLUSIONS

We created a Smartphone app (Fissios App) with a perioperative care program and it was successfully implemented regardless of the age or educational level of patients. The tool clearly explains the information contained and the patients reported that its use before surgery helped them to face the postoperative period, with an appropriate level of physical demand and time of use.

Prehabilitation before elective coronary artery bypass grafting surgery: a scoping review

OBJECTIVE

The objective of this scoping review was to identify and map existing preoperative interventions, referred to as prehabilitation, in adult patients at home awaiting elective coronary artery bypass grafting surgery. This review also sought to report feasibility and patient experiences to shape clinical practice and underpin a future systematic review.

INTRODUCTION

As patients age, comorbidities become more common. Strategies to improve postoperative outcomes and to accelerate recovery are required in patients undergoing coronary artery bypass grafting. Prehabilitation refers to a proactive process of increasing functional capacity before surgery to improve the patient's ability to withstand upcoming physiologic stress and, thus, avoid postoperative complications.

INCLUSION CRITERIA

Studies that included adult patients awaiting coronary artery bypass grafting surgery at home and that described interventions optimizing preoperative physical and psychological health in any setting were included.

METHODS

The JBI methodology for conducting scoping reviews was used to identify relevant studies in MEDLINE, CINAHL, Cochrane Library, Embase, Scopus, SweMed+, PsycINFO, and PEDro. Gray literature was identified searching Google Scholar, ProQuest Dissertations and Theses, MedNar, OpenGrey, NICE Evidence search, and SIGN. Studies in Danish, English, German, Norwegian, and Swedish were considered for inclusion, with no geographical or cultural limitations, or date restrictions. Two independent reviewers screened titles and abstracts, and studies meeting the inclusion criteria were imported into Covidence. Sixty-seven studies from November 1987 to September 2022 were included. The data extraction tool used for the included papers was developed in accordance with the review questions and tested for adequacy and comprehensiveness with the first 5 studies by the same 2 independent reviewers. The tool was then edited to best reflect the review questions. Extracted findings are described and supported by figures and tables.

RESULTS

Sixty-seven studies were eligible for inclusion, representing 28,553 participants. Analyses of extracted data identified various preoperative interventions for optimizing postoperative and psychological outcomes for adult patients awaiting elective coronary artery bypass grafting surgery. Based on similarities, interventions were grouped into 5 categories. Eighteen studies reported on multimodal interventions, 17 reported on psychological interventions, 14 on physical training interventions, 13 on education interventions, and 5 on oral health interventions.

CONCLUSION

This scoping review provides a comprehensive summary of strategies that can be applied when developing a prehabilitation program for patients awaiting elective coronary artery bypass surgery. Although prehabilitation has been tested extensively and appears to be feasible, available evidence is mostly based on small studies. For patients undergoing elective coronary artery bypass grafting to derive benefit from prehabilitation, methodologically robust clinical trials and knowledge synthesis are required to identify optimal strategies for patient selection, intervention design, adherence, and intervention duration. Future research should also consider the cost-effectiveness of prehabilitation interventions before surgery. Finally, there is a need for more qualitative studies examining whether individual interventions are meaningful and appropriate to patients, which is an important factor if interventions are to be effective.

Prähabilitation bei elektiver Lungen-Teilresektion (PRELS)

Hintergrund Lungenkrebs weist die höchste krebsbedingte Sterblichkeitsrate auf. Die chirurgische Resektion bei nicht kleinzelligem Lungenkrebs im Frühstadium bildet den Grundstein der Behandlung. Thoraxchirurgische Eingriffe sind mit einer erhöhten Rate an postoperativen Komplikationen verbunden, insbesondere bei verminderter präoperativer Leistungsfähigkeit. Das Enhanced Recovery Protocol stellt einen evidenzbasierten Ansatz für die Versorgung von Patient*innen dar, wobei ein wachsendes Interesse am Wert der Prähabilitation besteht. Prähabilitationsprotokolle, die auf eine Verbesserung der postoperativen Genesung abzielen, wurden als eine Intervention zur Verringerung der post-chirurgischen Beschwerden vorgeschlagen. Bis heute gibt es in der Schweiz keine etablierten Protokolle für ein präoperatives, körperliches Training.

Ziel Untersuchung der Machbarkeit eines präoperativen Trainingsprogramms für Patient*innen mit geplanter Lungenteilresektion.

Methoden Im Rahmen einer multizentrischen Machbarkeitsstudie wurden an 4 Schweizer Kliniken je 1 Person in ein präoperatives Training aufgenommen. Die Intervention bestand aus einem ambulanten Übungsprogramm mit Krafttraining und High-Intensity Intervall-Ausdauertraining für mindestens 1 Woche vor dem chirurgischen Eingriff. Die Endpunkte der Studie waren die Durchführbarkeit der präoperativen Rehabilitation und der Assessments sowie eine erste Abschätzung der Effekte.

Ergebnisse 4 Patient*innen wurden eingeschlossen. In allen Kliniken begannen die Patient*innen 21,5 ± 3 Tage vor der Operation mit dem Training, es gab keine Trainingsunterbrechungen. Es wurden keine unerwünschten Ereignisse beobachtet, was darauf hinweist, dass das präoperative Bewegungstraining sicher ist. Das vorgesehene Studiendesign konnte eingehalten werden. Die ausgewählten funktionellen Assessments sind durchführbar, sicher und die Ergebnisse sind für die Studie geeignet. Die Rekrutierung erwies sich jedoch als große Herausforderung.

Diskussion Die Ergebnisse zeigen, dass ein präoperatives Training durchführbar ist. Um das Rekrutierungspotenzial voll auszuschöpfen, ist es notwendig, die Risikostratifizierung, die organisatorischen Abläufe der beteiligten Kliniken zu spezifizieren und eine hohe Kooperationsbereitschaft aller beteiligten Disziplinen sicherzustellen bzw. zu definieren.

Schlussfolgerung Ein präoperatives, intensives Training vor einer geplanten Lungenteilresektion in 4 großen Spitälern der Schweiz war machbar. Es zeigten sich positive Effekte bezüglich Kraft und Ausdauer, zudem fühlten sich die Patient*innen in dieser Phase gut betreut. Ängste und Bedenken konnten frühzeitig adressiert und besprochen werden. Die Machbarkeitsstudie lieferte wertvolle Erkenntnisse für das Protokoll einer nachfolgenden Effektivitätsstudie.

Functional and postoperative outcomes after high-intensity interval training in lung cancer patients: A systematic review and meta-analysis

Objective

The study evaluated the effects of high-intensity interval training (HIIT) on postoperative complications and lung function in patients with lung cancer compared to usual care.

Methods

We searched electronic databases in April 2022, including PubMed, Embase, the Cochrane Library, Web of Science, and the China National Knowledge Infrastructure (CNKI). Two authors independently applied the Cochrane Risk of Bias tool to assess the quality of RCTs. The postoperative complications, length of hospitalization, and cardiopulmonary functions from the studies were pooled for statistical analysis.

Results

A total of 12 randomized controlled trials were eligible for inclusion and were conducted in the meta-analysis. HIIT significantly increased VO_2peak (MD = 2.65; 95% CI = 1.70 to 3.60; I² = 40%; P <0.001) and FEV1 (MD = 0.12; 95% CI = 0.04 to 0.20; I² = 51%; P = 0.003) compared with usual care. A subgroup analysis of studies that applied HIIT perioperatively showed significant improvement of HIIT on FEV1 (MD = 0.14; 95% CI = 0.08 to 0.20; I² = 36%; P <0.0001). HIIT significantly reduced the incidence of postoperative atelectasis in lung cancer patients compared with usual care (RD = -0.16; 95% CI = -0.24 to -0.08; I² = 24%; P <0.0001). There was no statistically significant effect of HIIT on postoperative arrhythmias (RD = -0.05; 95% CI = -0.13 to 0.03; I² = 40%; P = 0.22), length of hospitalization (MD = -1.64; 95% CI = -3.29 to 0.01; P = 0.05), and the six-minute walk test (MD = 19.77; 95% CI = -15.25 to 54.80; P = 0.27) compared to usual care.

Conclusion

HIIT may enhance VO_2peak and FEV1 in lung cancer patients and reduce the incidence of postoperative atelectasis. However, HIIT may not reduce the incidence of postoperative arrhythmia, shorten the length of hospitalization, or improve the exercise performance of patients with lung cancer.

Preoperative respiratory therapy in patients undergoing surgery for lung cancer: A randomized controlled trial

BACKGROUND

A preoperative respiratory therapy treatment was performed to analyze the effectiveness, with respect to postoperative air leak and pain, in patients undergoing surgery for lung cancer.

OBJECTIVES

To analyze air leakage and postoperative pain.

MATERIAL AND METHODS

Seventy one patients were studied, with a mean age of 62.58 years. Descriptive variables of gender, carcinogenic pathology, type of surgical incision and lung resection, use of glue and endostapler, and presence of adhesions were analyzed. Likewise, analysis of the quantitative variables of age, body mass index and forced expiratory volume in 1 s Two homogeneous groups resulted. Differentiated, experimental group (EG) that performed preoperative respiratory therapy and control group (CG).

RESULTS

There were statistically significant differences in favor of the EG with respect to postoperative air leak on days 1-2 during the performance of physiotherapy techniques, the food and during the performance of the exercises autonomously. Furthermore, differences in air leakage were observed on days 2-4 during gait. The number of patients decreased to a greater extent in the EG. Regarding pain, there were statistically significant differences in the sample on days 1-4, with greater intensity of pain in the CG and after doing physiotherapy every day except the second.

CONCLUSIONS

Preoperative respiratory therapy in patients undergoing surgery for lung cancer was effective in reducing the number of patients who presented postoperative air leak and reducing pain in the EG.

[KINE PREOP pilot study: Prehabilitation in fast-track thoracic surgery protocol]

INTRODUCTION

Prehabilitation preceding oncological thoracic surgery according to a fast-track enhanced recovery after surgery (ERAS) protocol is in full expansion. Many recent studies have demonstrated the benefits of preoperative pulmonary rehabilitation as a means of reducing postoperative pulmonary complications. Unfortunately, it is rarely carried out by independent physiotherapists, and questions arise: is it feasible in private practice? Can it yield results similar to those achieved in institutional settings?

DESIGN

The study was non-interventional. The patients included had to be able to practice physical activities according to a standard ERAS approach. The endpoints were: postoperative pulmonary complications, physical condition (VO2max), and impact on the quality of life (SF-36 questionnaire). A statistical study was conducted to analyze the results with parametric and non-parametric tests.

RESULTS

Between June 2018 and January 2019, nine patients were included. From two to fifteen pulmonary rehabilitation sessions were carried out by six volunteering independent physiotherapists. Only two minor postoperative complications ensued. VO2max post rehabilitation increased on average by 2.4mL.kg -1.min-1. The SF-36 physical score increased significantly (+17.9%). The physical functioning (PF) (+28.9), physical restrictions (PR) (+11.1) and vitality (VT) (+16.7) sub-scores likewise improved.

CONCLUSION

Based on a literature review and on comparisons, our results seem promising. While further investigations are needed, it would seem that prehabilitation by independent physiotherapists leads to results similar to those achieved in inpatient prehabilitation.

Effectiveness of healthy lifestyle-based interventions in lung cancer survivors: a systematic review and meta-analysis

PURPOSE

To assess the effectiveness of healthy lifestyle-based interventions in lung cancer survivors.

METHODS

We performed a literature search using PubMed, Web of Science, and Science Direct (last search March 2022). Quality assessment and risk of bias were assessed using the Downs and Black scale and the Cochrane tool. A systematic review and meta-analysis of randomized controlled trials were performed. We included controlled trials testing the effect of healthy lifestyle-based interventions in lung cancer survivors versus a control intervention where lung cancer patients had no treatment, were receiving the usual care, or had not an active role in the intervention. The data were pooled and a meta-analysis was completed for quality of life, psychological distress, and cancer-related symptoms.

RESULTS

We selected 14 studies, which included 1519 patients with lung cancer. The treatment status of these patients was heterogeneous. Healthy lifestyle programs were applied isolated or in combination with usual care in most of the studies. The components of the healthy lifestyle programs were also heterogeneous. Results showed significant differences in favor of healthy lifestyle-based interventions in comparison to the control group for quality of life (p = 0.01), psychological distress (p = 0.05), and cancer-related symptoms (p = 0.03).

CONCLUSIONS

The findings indicated a beneficial effect of healthy lifestyle-based interventions for improving quality of life, psychological distress, and cancer-related symptoms in lung cancer patients. However, this review could not show any conclusion about the better treatment moment to apply healthy lifestyle-based interventions.

Timed up and go test and long-term survival in older adults after oncologic surgery

BACKGROUND

Physical performance tests are a reflection of health in older adults. The Timed Up and Go test is an easy-to-administer tool measuring physical performance. In older adults undergoing oncologic surgery, an impaired TUG has been associated with higher rates of postoperative complications and increased short term mortality. The objective of this study is to investigate the association between physical performance and long term outcomes.

METHODS

Patients aged ≥65 years undergoing surgery for solid tumors in three prospective cohort studies, 'PICNIC', 'PICNIC B-HAPPY' and 'PREOP', were included. The TUG was administered 2 weeks before surgery, a score of ≥12 seconds was considered to be impaired. Primary endpoint was 5-year survival, secondary endpoint was 30-day major complications. Survival proportions were estimated using Kaplan-Meier curves. Cox- and logistic regression analysis were used for survival and complications respectively. Hazard ratios (aHRs) and Odds ratios (aOR) were adjusted for literature-based and clinically relevant variables, and 95% confidence intervals (95% CIs) were estimated using multivariable models.

RESULTS

In total, 528 patients were included into analysis. Mean age was 75 years (SD 5.98), in 123 (23.3%) patients, the TUG was impaired. Five-year survival proportions were 0.56 and 0.49 for patients with normal TUG and impaired TUG respectively. An impaired TUG was an independent predictor of increased 5-year mortality (aHR 1.43, 95% CI 1.02-2.02). The TUG was not a significant predictor of 30-day major complications (aOR 1.46, 95% CI 0.70-3.06).

CONCLUSIONS

An impaired TUG is associated with increased 5-year mortality in older adults undergoing surgery for solid tumors. It requires further investigation whether an impaired TUG can be reversed and thus improve long-term outcomes.

Cancer Prehabilitation in Practice: the Current Evidence

PURPOSE OF REVIEW

This article serves to describe recent controversies in cancer prehabilitation including efficacy, dose, cost effectiveness, stakeholder input, and international implementation.

RECENT FINDINGS

Appropriate frequency, type, and timing have yet to be determined, but high intensity exercise is recommended. Costs are favorable when modeled and information on costs of real-world application are forthcoming. Patients are interested in and willing to attend cancer prehabilitation. Cancer prehabilitation research is spreading throughout the world. Cancer prehabilitation includes assessment of a newly diagnosed cancer patient's baseline fitness and targeted interventions to improve their health before surgery, chemotherapy, or radiation. Cancer prehabilitation improves fitness as measured preoperatively and improves outcomes postoperatively.

Preoperative exercise training for people with non-small cell lung cancer

BACKGROUND

Surgical resection for early-stage non-small cell lung cancer (NSCLC) offers the best chance of cure, but it is associated with a risk of postoperative pulmonary complications. It is unclear if preoperative exercise training, and the potential resultant improvement in exercise capacity, may improve postoperative outcomes. This review updates our initial 2017 systematic review.

OBJECTIVES

1. To evaluate the benefits and harm of preoperative exercise training on postoperative outcomes, such as the risk of developing a postoperative pulmonary complication and the postoperative duration of intercostal catheter, in adults scheduled to undergo lung resection for NSCLC. 2. To determine the effect on length of hospital stay (and costs associated with postoperative hospital stay), fatigue, dyspnoea, exercise capacity, lung function and postoperative mortality.

SEARCH METHODS

We used standard, extensive Cochrane search methods. The latest search date was from 28 November 2016 to 23 November 2021.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) in which study participants who were scheduled to undergo lung resection for NSCLC were allocated to receive either preoperative exercise training or no exercise training.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were 1. risk of developing a postoperative pulmonary complication; 2. postoperative duration of intercostal catheter and 3.

SAFETY

Our secondary outcomes were 1. postoperative length of hospital stay; 2. postintervention fatigue; 3. postintervention dyspnoea; 4. postintervention and postoperative exercise capacity; 5. postintervention lung function and 6. postoperative mortality. We used GRADE to assess the certainty of evidence for each outcome.

MAIN RESULTS

Along with the five RCTs included in the original version, we identified an additional five RCTs, resulting in 10 RCTs involving 636 participants. Preoperative exercise training results in a large reduction in the risk of developing a postoperative pulmonary complication compared to no preoperative exercise training (risk ratio (RR) 0.45, 95% CI 0.33 to 0.61; I2 = 0%; 9 studies, 573 participants; high-certainty evidence). The evidence is very uncertain about its effect on postoperative intercostal catheter duration (MD -2.07 days, 95% CI -4.64 to 0.49; I2 = 77%, 3 studies, 111 participants; very low-certainty evidence). Preoperative exercise training is likely safe as studies reported no adverse events. Preoperative exercise training likely results in a reduction in postoperative length of hospital stay (MD -2.24 days, 95% CI -3.64 to -0.85; I2 = 85%; 9 studies, 573 participants; moderate-certainty evidence). Preoperative exercise training likely increases postintervention exercise capacity measured by peak oxygen consumption (MD 3.36 mL/kg/minute, 95% CI 2.70 to 4.02; I2 = 0%; 2 studies, 191 participants; moderate-certainty evidence); but the evidence is very uncertain about its effect on postintervention exercise capacity measured by the 6-minute walk distance (MD 29.55 m, 95% CI 12.05 to 47.04; I2 = 90%; 6 studies, 474 participants; very low-certainty evidence). Preoperative exercise training may result in little to no effect on postintervention lung function (forced expiratory volume in one second: MD 5.87% predicted, 95% CI 4.46 to 7.28; I2 = 0%; 4 studies, 197 participants; low-certainty evidence).  AUTHORS' CONCLUSIONS: Preoperative exercise training results in a large reduction in the risk of developing a postoperative pulmonary complication compared to no preoperative exercise training for people with NSCLC. It may also reduce postoperative length of hospital stay, and improve exercise capacity and lung function in people undergoing lung resection for NSCLC. The findings of this review should be interpreted with caution due to risk of bias. Research investigating the cost-effectiveness and long-term outcomes associated with preoperative exercise training in NSCLC is warranted.

The Effects of Multimodal Prehabilitation Interventions in Men Affected by Prostate Cancer on Physical, Clinical and Patient Reported Outcome Measures: A Systematic Review

OBJECTIVES

To synthesize existing evidence on the effects of multimodal prehabilitation interventions in men affected by prostate cancer on physical, clinical, and patient-reported outcome measures.

DATA SOURCES

A systematic review was conducted according to the PRISMA 2020 Statement Guidelines. Electronic databases (ie, Medline, Embase, CINAHL and Cochrane CENTRAL, and clinicaltrials.gov) were searched using key search terms. Articles were assessed according to prespecified eligibility criteria. Data extraction and quality appraisal was conducted. The findings were integrated in a narrative synthesis.

CONCLUSION

Of the 5863 publications screened, 118 articles were assessed in full text and 17 studies met the prescreening eligibility criteria. There were a range of study designs that included randomized controlled clinical trials (n = 11), quasi experimental (n = 4), cohort (n = 1), and case series (n = 1), covering a total of 1739 participants. The prehabilitation interventions included physical activity, peer support, pelvic floor muscle training, diet, nurse-led prehabilitation, psychological, and prehabilitation administration of phosphodiesterase-5 inhibitors.

IMPLICATIONS FOR NURSING PRACTICE

Significant heterogeneity existed in the prehabilitation intervention programs for men affected by prostate cancer in terms of the composition, duration, method of administration, and the outcomes measured to quantify their impact. This systematic review has identified that multimodal prehabilitation interventions are an emerging area for practice and research among men affected by prostate cancer. Importantly, there has been a lack of focus on the inclusion of partners as critical companions during this distressing phase of the cancer care continuum. For the moment, all members of the multidisciplinary team caring for people affected by prostate cancer are encouraged to use the findings in this review to inform holistic models of care.

Recovery of respiratory muscle strength, physical function, and dyspnoea after lobectomy in lung cancer patients undergoing pulmonary rehabilitation: A retrospective study

OBJECTIVE

To characterise changes in respiratory muscle strength, physical function, and dyspnoea in patients who underwent pre- and post-operative exercise intervention following lobectomy for non-small-cell lung cancer (NSCLC).

METHODS

This retrospective study included NSCLC patients who underwent lobectomy via video-assisted thoracoscopic surgery (VATS) or posterolateral thoracotomy (PLT) and pre- and post-operative exercise intervention consisting of breathing, flexibility, resistance, aerobic exercises, coughing/huffing techniques, and early mobilisation. Maximum mouth inspiratory (Pimax) and expiratory pressures (Pemax), 6-min walk distance (6MWD), quadriceps force (QF), and modified Medical Research Council (mMRC) dyspnoea scale were evaluated preoperatively, at hospital discharge, and post-lobectomy 1 and 3 months.

RESULTS

Data from 41 patients were analysed. At hospital discharge, the Pimax, Pemax, 6MWD, and mMRC dyspnoea scores were lower than pre-operatively; QF remained unchanged; Pimax and 6MWD recovered to pre-operative values at post-lobectomy 1 month; and Pemax and mMRC dyspnoea scores recovered at 3 months. During sub-analysis, Pimax and mMRC dyspnoea scores in the VATS (n = 24) and PLT groups (n = 17) recovered to pre-operative values at post-lobectomy 1 and 3 months.

CONCLUSION

After lobectomy, respiratory muscle strength, physical function, and dyspnoea in patients who underwent exercise intervention returned to pre-operative values at post-lobectomy 3 months.

Effectiveness of Preoperative Chest Physiotherapy in Patients Undergoing Elective Cardiac Surgery, a Systematic Review and Meta-Analysis

Background and Objectives: Patients undergoing cardiac surgery are particularly vulnerable for developing postoperative pulmonary complications (PPCs). This systematic review and meta-analysis aimed to evaluate the role of preoperative chest physiotherapy in such patients. Materials and Methods: All original articles that assessed patients undergoing elective cardiac surgery, with preoperative chest physiotherapy, and compared them to patients undergoing elective cardiac surgery, without preoperative chest physiotherapy, were included. Animal studies, studies conducted prior to the year 2000, commentaries, or general discussion papers whose authors did not present original data were excluded. Studies assessing physiotherapy regimens other than chest physiotherapy were also excluded. The search was performed using the following electronic resources: the Cochrane Central Register of Controlled Trials, the PubMed central database, and Embase. The included studies were assessed for potential bias using the Cochrane Collaboration’s tool for assessing the risk of bias. Each article was read carefully, and any relevant data were extracted. The extracted data were registered, tabulated, and analyzed using Review Manager software. Results: A total of 10 articles investigating 1458 patients were included in the study. The studies were published from 2006 to 2019. The populations were patients scheduled for elective CABG/cardiac surgery, and they were classified into two groups: the interventional (I) group, involving 651 patients, and the control (C) group, involving 807 patients. The meta-analysis demonstrated no significant differences between the interventional and control groups in surgery time and ICU duration, but a significant difference was found in the time of mechanical ventilation and the length of hospital stay, favoring the interventional group. A significant difference was shown in the forced expiratory volume in 1s (FEV1% _predicted), forced vital capacity (FVC% _predicted), and maximum inspiratory pressure (Pi-max), favoring the interventional group. Conclusions: This study is limited by the fact that one of the included ten studies was not an RCT. Moreover, due to lack of the assessment of certain variables in some studies, the highest number of studies included in a meta-analysis was the hospital stay length (eight studies), and the other variables were analyzed in a fewer number of studies. The data obtained can be considered as initial results until more inclusive RCTs are conducted involving a larger meta-analysis. However, in the present study, the intervention was proved to be protective against the occurrence of PPCs. The current work concluded that preoperative chest physiotherapy can yield better outcomes in patients undergoing elective cardiac surgery.

The influence of physical activity level on the length of stay in hospital in older men survivors of COVID-19

The purpose of this study was to verify the influence of physical activity level on the length of hospital stay in older men recovered from COVID-19. In total, 126 older men diagnosed with COVID-19 were admitted to the hospital between September and December 2020. Among them, 70 survived, of which 39 older men were included in the study. Within 30 days after discharge, patients answered the International Physical Activity Questionnaire to measure their physical activity level through phone contact, with questions corresponding to the week before symptom onset. Clinical and laboratorial data from admission, days between onset of symptoms and admission, length of stay, computed tomography abnormalities, and the need for the intensive care unit were collected. The groups (active × sedentary) were compared using the Student t test or Mann-Whitney test for quantitative data and chi-square test was used for categorical data. There is no difference between the groups in characteristics of admission (p > 0.05), except by potassium level. Active older men had a shorter length of stay (6.50 ± 3.46 vs 11.48 ± 7.63 days; p = 0.03), disease duration (15.71 ± 4.84 vs 21.09 ± 7.69 days; p = 0.02), and lower frequency of lung damage when compared to their sedentary counterparts. In conclusion, being physically active prior to infection can attenuate length of hospital stay in older men with COVID-19.

Telerehabilitation physical exercise for patients with lung cancer through the course of their disease: A systematic review

BACKGROUND AND OBJECTIVE

Evidence is shown for the benefits of physical activity, for patients with lung cancer, at different times through the course of the disease. Telerehabilitation can overcome some of barriers often met by patients to practice physical activity. The objective of this systematic review is to assess feasibility and safety of telerehabilitation for patients with lung cancer, its effects on physical capacity, quality of life, symptoms severity, depression and anxiety, survival, lung function, post-operative outcomes, dyspnoea and body composition. Secondary aim was to distinguish the telerehabilitation efficacy between the different phases of the disease.

DATA SOURCE AND SELECTION CRITERIA

Pubmed, PEDro, Scopus, ScienceDirect, randomized controlled trials and non-randomized controlled trials, written in French or English, of telerehabilitation among patients with lung cancer.

RESULTS

Eight studies were included. Telerehabilitation is safe but was characterized by a low recruitment and attendance rate (<70%). It enhances quality of life, muscle mass, depression and anxiety but it does not improve physical capacity (except in preoperative period), symptoms severity, survival, lung function or dyspnoea. After surgery, it ameliorates quality of life, depression and anxiety. During systemic treatments of lung cancer, it improves quality of life, symptoms severity and muscle mass.

CONCLUSION

Telerehabilitation could be proposed in patients with lung cancer as a complementary intervention of hospital-based programme to increase physical activity volume, compliance and self-efficacy. In case the classic programmes are not possible, it could also be an alternative approach for patients unable to participate to a hospital or community-based training programme.

Spontaneous Ventilation Video-Assisted Thoracoscopic Surgery for Non-small-cell Lung Cancer Patients With Poor Lung Function: Short- and Long-Term Outcomes

Objective

The goal of this study was to explore the feasibility and safety of spontaneous ventilation video-assisted thoracoscopic surgery (SV-VATS) for non-small-cell lung cancer (NSCLC) patients with poor lung function.

Methods

NSCLC patients with poor lung function who underwent SV-VATS or mechanical ventilation VATS (MV-VATS) from 2011 to 2018 were analyzed. 1:2 Propensity score matching (PSM) was applied, and the short- and long-term outcomes between the SV-VATS group and the MV-VATS group were compared.

Results

Anesthesia time (226.18 ± 64.89 min vs. 248.27 ± 76.07 min; P = 0.03), operative time (140.85 ± 76.07 min vs. 163.12 ± 69.37 min; P = 0.01), days of postoperative hospitalization (7.29 ± 3.35 days vs. 8.40 ± 7.89 days; P = 0.04), and days of chest tube use (4.15 ± 2.89 days vs. 5.15 ± 3.54 days; P = 0.01), the number of N1 station lymph node dissection (2.94 ± 3.24 vs. 4.34 ± 4.15; P = 0.005) and systemic immune-inflammation index (3855.43 ± 3618.61 vs. 2908.11 ± 2933.89; P = 0.04) were lower in SV-VATS group. Overall survival and disease-free survival were not significantly different between the two groups (OS: HR 0.66, 95% CI: 0.41–1.07, P = 0.09; DFS: HR 0.78, 95% CI: 0.42–1.45, P = 0.43).

Conclusions

Comparable short-term and long-term outcomes indicated that SV-VATS is a feasible and safe method and might be an alternative to MV-VATS when managing NSCLC patients with poor lung function.

Psychological Interventions Prior to Cancer Surgery: a Review of Reviews

Purpose of Review

Patients with cancer who have high levels of psychological distress have poor treatment compliance and worse outcomes. This “review of reviews” provides a narrative synthesis of the impact of psychological prehabilitation interventions on individuals awaiting cancer surgery.

Recent Findings

Twenty reviews of prehabilitation with psychological interventions were identified. There is a trend towards improved psychological outcomes following intervention, particularly when psychologist-led. However, there was considerable heterogeneity within interventions, outcome measures, and timing of assessment precluding numeric synthesis. Methodological limitations including non-blinding, absence of stratification, and underpowered studies were also pervasive.

Summary

Providing psychological support early in the cancer pathway and prior to surgery has the potential to improve psychological health and outcomes. The application of existing knowledge in psycho-oncology, including distress screening, is needed in the prehabilitation setting. Consistent outcome assessments, accurate reporting of intervention components and delivery methods, and a consideration of effective systems and economical implementation strategies would facilitate advancements in this field.

[Correlation Analysis of the Lung Volume Reduction and the Lung Function Loss after the Thoracoscopic Lobectomy]

BACKGROUND

To investigate the correlation between the reduction of lung volume and the degree of lung function damage after lobectomy.

METHODS

A total of 131 patients (72 males and 59 females) who underwent thoracoscopic lobectomy in the First Affiliated Hospital of Suzhou University from January 2019 to July 2020 (including thoracoscopic resection of left upper lobe, left lower lobe, right upper lobe, right middle lobe and right lower lobe). In order to compare the difference between postoperative pulmonary function and preoperative pulmonary function, the pulmonary function measurements were recorded at 7 days before operation, and 3 months, 6 months and 1 year after operation. Forced expiratory volume in 1 second (FEV1) was used as the main evaluation parameter of pulmonary function. The original lung volume and the remaining lung volume at each stage were calculated by Mimics Research 19.0 software. The correlation between lung volume and lung function was analyzed.

RESULTS

FEV1 in postoperative patients was lower than that before operation, and the degree of decline was positively correlated with the resection volume of lung lobes (the maximum value was shown in the left lower lobe group). Significantly, there was no significant difference in the degree of pulmonary function reduction between 3 months, 6 months and 1 year after operation.

CONCLUSIONS

The decrease of lung tissue volume after lobectomy is the main reason for the decrease of lung function, especially in the left lower lobe. And 3 months after lobectomy can be selected as the evaluation node of residual lung function.

Mapping a decade of interventions to address the supportive care needs of individuals living with or beyond cancer: a scoping review of reviews

PURPOSE

Individuals diagnosed with cancer have a range of supportive care needs that are often unmet despite substantial evidence supporting interventions to address them. Addressing this knowledge-translation gap represents a significant opportunity to improve health outcomes. A scoping review of reviews was conducted to map the breadth of evidence for interventions, highlighting those with an existing evidence base, as well as those requiring further research.

METHODS

Systematic or meta-analytic reviews that examined interventions targeting supportive care needs of adults and children with cancer published between 2009 and 2019 were identified via searches in Medline, PsycINFO, CINAHL, Scopus and Cochrane.

RESULTS

Five hundred fifty-one systematic reviews, including 250 meta-analyses, of interventions addressing supportive care needs, were included. Most reviews focused on interventions to address the physical and psychosocial needs of individuals with few reviews identified to address practical needs. Interventions using mental health therapies and physical activity were most commonly used to address all supportive care needs, followed by the use of pharmaceutical and medical devices, complementary and alternative therapies, information and education resources, dietary information and specific spirituality and return-to-work interventions.

CONCLUSION

This scoping review of reviews presents the first broad overview of the literature addressing the supportive care needs of people living with or beyond cancer. It provides a database that health service providers can search to identify appropriate interventions. Results highlight specific research gaps, particularly for practical needs, where reviews are needed. It highlights where a substantial evidence base exists that researchers and policy-makers can consider when implementing interventions.

Do Cancer and Cancer Treatments Accelerate Aging?

PURPOSE OF REVIEW

This review focuses on describing the mechanisms and clinical manifestations that underlie accelerated aging associated with cancer and its treatment.

RECENT FINDINGS

The direct and indirect effects of cancer and its treatment are associated with late occurrence of comorbidities that happen earlier or more frequently in cancer survivors compared to cancer-free individuals, otherwise known as accelerated aging. Use of senolytics and dietary and exercise interventions including prehabilitation, caloric restriction, and rehabilitation are currently under investigation to reverse or decelerate the aging process and will be covered in this review. Further research on how to decelerate or reverse aging changes associated with cancer and its treatment will be of paramount importance as the number of cancer survivors continues to grow.

Effect of physical manipulation pulmonary rehabilitation on lung cancer patients after thoracoscopic lobectomy

Background

To introduce a new postoperative pulmonary rehabilitation program named physical manipulation pulmonary rehabilitation (PMPR) and to explore the effect of perioperative management, including PMPR, on patients with non‐small cell lung cancer (NSCLC) after thoracoscopic lobectomy.

Methods

A randomized controlled trial was conducted between April and June 2021 at the Department of Thoracic Surgery, Beijing Hospital. Adult patients with NSCLC who had undergone thoracoscopic lobectomy were allocated to the treatment and control groups using a random number table. The treatment group received both conventional pulmonary rehabilitation (CVPR) and 14 days of PMPR after surgery; the control group patients received CVPR only. PMPR included relaxing and exercising the intercostal muscles, thoracic costal joint and abdominal breathing muscles. Pulmonary function tests and the 6‐min walk test were conducted preoperatively and 7, 14, 21 and 28 days postoperatively. The postoperative length of hospital stay, chest tube retention time and postoperative pulmonary complications were recorded. The baseline data, pulmonary function parameters and prognosis were compared with t‐ and chi‐square tests between the two groups.

Results

A total of 86 patients were enrolled, and 44 patients were allocated to the treatment group. There were no significant differences in the baseline data for age, sex, body mass index, basic disease, surgical plan or preoperative pulmonary function between the two groups (all p > 0.05). The peak expiratory flow of patients in the treatment group was higher than that of those in the control group 21 days after surgery (316 ± 95 vs. 272 ± 103 l/min, respectively, p = 0.043), and forced expiratory volume in the first second on day 28 after surgery was greater than that in the control group (2.1 ± 0.2 vs. 1.9 ± 0.3 L, respectively, p < 0.001). There were no significant differences in forced vital capacity or 6‐min walk test scores (both p > 0.05). There were no significant differences in the incidences of pneumonia and atelectasis between the two groups (both p > 0.05). The postoperative length of hospital stay (3.3 ± 1.3 vs. 3.9 ± 1.5 days, p = 0.043) and chest tube retention time (66 ± 30 vs. 81 ± 35 h, p = 0.036) in the treatment group were shorter than those in the control group.

Conclusions

We determined that PMPR could improve early lung function in patients with NSCLC after thoracoscopic lobectomy, and that chest tube retention time and length of hospital stay were shortened.

Correlation between physical status measures and frailty score in patients undergoing pancreatic resection

BACKGROUND

This study aimed to assess the correlation between validated measures of physical status in a prehabilitation regimen with an established frailty score and analyze changes in these measures after completion of a directed prehabilitation program among patients undergoing elective pancreatic resection.

METHODS

Adult patients undergoing pancreatic resection from 2019-2021 were enrolled in a pilot prehabilitation program. Three validated measures of physical status were used: the 6-minute walk test, grip strength, and chair-stand test. The prehabilitation program comprised 7,500 steps, 30 grip strength exercises, and 100 chair-stand exercises daily. Patients' frailty score was calculated using the Modified Johns Hopkins Frailty score. Changes in physical status measures after prehabilitation and postoperative outcomes were compared.

RESULTS

Thirty-two patients with a median age of 69.0 years (interquartile range = 59.5-76.3 years) were included. Patients' median duration of participation was 21.5 days (interquartile range = 16-29 days). There was a negative correlation between increasing frailty score and baseline the 6-minute walk test (R² = 0.17) and chair-stand test (R² = 0.18). Patients' mean the 6-minute walk test decreased at the end of the prehabilitation program, while grip strength and chair-stand test were unchanged. When stratified by low or intermediate and high frailty scores, the differences in the 6-minute walk test and chair-stand test were unchanged. Hospital duration of stay, complications, and 90-day readmission rates were not different between frailty groups (P > .05).

CONCLUSION

Correlation of physical status measures with frailty score suggests only one of these measures is sufficient to estimate patients' preoperative physical status. A longer, more comprehensive prehabilitation program or an expedited operation are likely the best strategies to improve patient outcomes.

Effects of Prehabilitation on Functional Capacity in Aged Patients Undergoing Cardiothoracic Surgeries: A Systematic Review

Background: an increasing number of advanced age patients are considered for cardiothoracic surgeries. Prehabilitation optimizes the patients’ functional capacity and physiological reserve. However, the effectiveness of prehabilitation on physical functioning and postoperative recovery in the scope of cardiothoracic surgery is still uncertain. Objective: to assess the effectiveness of prehabilitation on pre- and/or postoperative functional capacity and physiological reserve in aged patients that are considered for cardiothoracic surgeries. Methods: this systematic review was registered in PROSPERO (CRD42021247117). The searches were conducted in PubMed, Web of Science, Scopus, and Cochrane CENTRAL until 18 April 2021. Randomized clinical trials that compared different prehabilitation strategies with usual care on the pre- and-postoperative results in aged patients undergoing cardiothoracic surgeries were included. Methodological quality was assessed by means of the Jadad scale, and the effectiveness of the interventions according to the Consensus on Therapeutic Exercise Training. Results: nine studies with 876 participants aged from 64 to 71.5 years old were included. Risk of bias was moderate due to the absence of double-blinding. The content of the interventions (multimodal prehabilitation n = 3; based on physical exercises n = 6) and the result measures presented wide variation, which hindered comparison across the studies. In general, the trials with better therapeutic quality (n = 6) reported more significant improvements in physical functioning, cardiorespiratory capacity, and in the postoperative results in the participants under-going prehabilitation. Conclusions: prehabilitation seems to improve functional capacity and postoperative recovery in aged patients undergoing cardiothoracic surgeries. However, due to the significant heterogeneity and questionable quality of the trials, both the effectiveness of prehabilitation and the optimum content are still to be determined.

Perioperative exercise intervention in patients with lung cancer: A systematic literature review of randomized controlled trials

Objectives:

During perioperative, lung cancer (LC) patients are often left to experience debilitating disease-related symptoms, impaired physical activity and health-related quality of life (HRQoL), and social difficulties, despite the progress achieved in terms of treatment efficacy. Nonpharmacological intervention, such as exercise, has been identified as an effective strategy in LC patients before and after lung resection. Therefore, we aimed to assess evidence of the effect of perioperative exercise among patients with LC.

Materials and Methods:

Seven databases were searched from January 1998 to September 2020. All randomized controlled trials (RCTs) that evaluated the effect of exercise on the physical and psychological status of patients with LC during the perioperative period were reviewed. Two reviewers independently assessed the quality of all studies included here using the revised Cochrane risk of bias tool for RCTs.

Results:

Seventeen RCTs (1199 participants) published between 2011 and 2019 met for this literature review. The outcome measures that emerged from these studies included subjective outcomes, such as HRQoL, pain score, fatigue, and objective effects, such as cardiorespiratory fitness, pulmonary function, physical activity, and biological markers. Overall, these studies suggest that exercise should be an optimal option for LC; however, its efficacy and effectiveness regarding HRQoL should be investigated further.

Conclusion:

Perioperative exercise could be included in the rehabilitation program of patients with LC. More extensive, high-quality RCTs evidence is needed on the ideal exercise type, duration, intensity, and timing across the LC perioperative care.

Prehabilitation as an important stage before cardiac surgery

The review discusses the preparation of patients for surgery on the heart and other organs. We considered the importance of introducing a new stage of medical and cardiology rehabilitation — prehabilitation. The results of randomized clinical trials, systematic reviews and metaanalyzes evaluating the effectiveness of respiratory techniques and physical training during the prehabilitation are presented. Particular attention is paid to the involvement of patients in prehabilitation programs before the elective coronary artery bypass grafting. Methodological problems arising in the development of prehabilitation programs are discussed.

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.

Effect of Exercise Training on Quality of Life after Colorectal and Lung Cancer Surgery: A Meta-Analysis

Surgical treatment affects health-related quality of life (HRQoL) and increases fatigue symptoms in patients with lung cancer (LC) and colorectal cancer (CRC). We aimed to systematically review the effect of exercise training on HRQoL and fatigue after LC and CRC surgery. Randomized controlled trials published before 21 March 2021, were searched in PubMed, Scopus, Web of Science, SPORTDiscus and PEDro. Eligible trials compared the effect of exercise interventions initiated preoperatively or in the first 3 months after surgery versus usual care on postoperative HRQoL and fatigue. Standardized mean differences (SMD) were pooled using random-effects models. Twelve studies with a total of 777 patients were included. In LC patients (10 studies, n = 651), exercise training in general led to a moderate improvement in the physical domain of HRQoL (0.68: 95% CI: [0.47; 0.89]) and a small reduction in fatigue levels after surgery (SMD = 0.28: 95% CI: [0.02; 0.53]), while no effects were found in other HRQoL domains. In CRC (two studies, n = 126), exercise training showed no effects on HRQoL and fatigue after surgery. Exercise training is an effective intervention to improve physical function and fatigue after LC surgery. Further studies are necessary to clarify the effects of exercise on HRQoL and fatigue after CRC surgery.

The effectiveness of pre- and post-operative rehabilitation for lung cancer: A systematic review and meta-analysis on postoperative pulmonary complications and length of hospital stay

OBJECTIVE

To investigate the effects of rehabilitation either before or after operation for lung cancer on postoperative pulmonary complications and the length of hospital stay.

DATA SOURCES

MEDLINE, Cochrane Central Register of Controlled Trials, Web of Science, CINAHL Plus, SPORTDiscus, PsycInfo and Embase were searched from inception until June 2021.

REVIEW METHODS

Inclusion criteria were patients scheduled to undergo or had undergone operation for lung cancer, randomised controlled trials comparing rehabilitative interventions initiated before hospital discharge to usual care control. Two reviewers independently assessed eligibility, extracted data and risks of bias. Pooled odds ratios (ORs) or standardised mean differences (SMDs) with 95% Confidence Intervals (CI) were estimated using random-effects meta-analyses.

RESULTS

Twenty-three studies were included (12 preoperative, 10 postoperative and 1 perioperative), with 2068 participants. The pooled postoperative pulmonary complication risk and length of hospital stay were reduced after preoperative interventions (OR = 0.32; 95% CI = 0.22, 0.47; I² = 0.0% and SMD = -1.68 days, 95% CI = -2.23, -1.13; I² = 77.8%, respectively). Interventions delivered during the immediate postoperative period did not have any significant effects on either postoperative pulmonary complication or length of hospital stay (OR = 0.85; 95% CI = 0.56, 1.29; I² = 0.0% and SMD = -0.23 days, 95% CI = -1.08, 0.63; I² = 64.6%, respectively). Meta-regression showed an association between a higher number of supervised sessions and shorter hospital length of stay in preoperative studies (β = -0.17, 95% CI = -0.29, -0.05).

CONCLUSION

Preoperative rehabilitation is effective in reducing postoperative pulmonary complications and length of hospital stay associated with lung cancer surgery. Short-term postoperative rehabilitation in inpatient settings is probably ineffective.
