Effectiveness of prehabilitation during neoadjuvant therapy for patients with esophageal or gastroesophageal junction cancer: a systematic review

Progression of the physical weakness during neoadjuvant therapy (NAT) in patients with esophageal or gastroesophageal junction cancer is a serious problem; however, prehabilitation during NAT has the potential to overcome the unmet need. Nevertheless, systematic reviews on this topic have not been summarized. Therefore, this systematic review aimed to determine prehabilitation's effectiveness, acceptability, and safety during NAT for patients with esophageal or gastroesophageal junction cancer. An electronic search was performed in the MEDLINE, Web of Science, CENTRAL, CINAHL, and PEDro databases. A meta-analysis was conducted to assess the effectiveness of prehabilitation during NAT, along with a descriptive analysis of acceptance and safety. This study analyzed data from three randomized controlled trials (RCTs) and nine non-RCTs involving 664 patients. The meta-analysis of two RCTs demonstrated that prehabilitation during NAT may be more effective than usual care in enhancing tolerance to NAT and grip strength; moreover, one RCT and three non-RCTs revealed that prehabilitation may reduce the risk of postoperative complications. The adherence rates for exercise programs in two RCTs and seven non-RCTs were 55-76%. Additionally, two studies reported a 76% adherence rate for multimodal prehabilitation programs, including exercise, dietary, and psychological care. Six studies reported no serious prehabilitation-related adverse events during NAT. Prehabilitation during NAT may be a safe and beneficial intervention strategy for patients with esophageal or gastroesophageal junction cancer. However, the investigation of strategies to enhance adherence is essential. Furthermore, additional high-quality RCTs are needed to examine the effect of prehabilitation during NAT.

Effectiveness of Prehabilitation Modalities on Postoperative Outcomes Following Colorectal Cancer Surgery: A Systematic Review of Randomised Controlled Trials

BACKGROUND

Postoperative morbidity in patients undergoing curative colorectal cancer surgery is high. Prehabilitation has been suggested to reduce postoperative morbidity, however its effectiveness is still lacking.

OBJECTIVE

The aim of this study was to investigate the effectiveness of prehabilitation in reducing postoperative morbidity and length of hospital stay in patients undergoing colorectal cancer surgery.

METHODS

A comprehensive electronic search was conducted in the CINAHL, Cochrane Library, Medline, PsychINFO, AMED, and Embase databases from inception to April 2023. Randomised controlled trials testing the effectiveness of prehabilitation, including exercise, nutrition, and/or psychological interventions, compared with usual care in patients undergoing colorectal cancer surgery were included. Two independent review authors extracted relevant information and assessed the risk of bias. Random-effect meta-analyses were used to pool outcomes, and the quality of evidence was assessed using Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) guidelines.

RESULTS

A total of 23 trials were identified (N = 2475 patients), including multimodal (3 trials), exercise (3 trials), nutrition (16 trials), and psychological (1 trial) prehabilitation. There was moderate-quality evidence that preoperative nutrition significantly reduced postoperative infectious complications (relative risk 0.65, 95% confidence interval [CI] 0.45-0.94) and low-quality evidence on reducing the length of hospital stay (mean difference 0.87, 95% CI 0.17-1.58) compared with control. A single trial demonstrated an effect of multimodal prehabilitation on postoperative complication.

CONCLUSION

Nutrition prehabilitation was effective in reducing infectious complications and length of hospital stay. Whether other multimodal, exercise, and psychological prehabilitation modalities improve postoperative outcomes after colorectal cancer surgery is uncertain as the current quality of evidence is low.

An Immersive Virtual Reality Intervention for Preoperative Anxiety and Distress Among Adults Undergoing Oncological Surgery: Protocol for a 3-Phase Development and Feasibility Trial

BACKGROUND

Preoperative state anxiety (PSA) is distress and anxiety directly associated with perioperative events. PSA is associated with negative postoperative outcomes such as longer hospital length of stay, increased pain and opioid use, and higher rates of rehospitalization. Psychological prehabilitation, such as education, exposure to hospital environments, and relaxation strategies, has been shown to mitigate PSA; however, there are limited skilled personnel to deliver such interventions in clinical practice. Immersive virtual reality (VR) has the potential for greater accessibility and enhanced integration into an immersive and interactive experience. VR is rarely used in the preoperative setting, but similar forms of stress inoculation training involving exposure to stressful events have improved psychological preparation in contexts such as military deployment.

OBJECTIVE

This study seeks to develop and investigate a targeted PSA intervention in patients undergoing oncological surgery using a single preoperative VR exposure. The primary objectives are to (1) develop a novel VR program for patients undergoing oncological surgery with general anesthesia; (2) assess the feasibility, including acceptability, of a single exposure to this intervention; (3) assess the feasibility, including acceptability, of outcome measures of PSA; and (4) use these results to refine the VR content and outcome measures for a larger trial. A secondary objective is to preliminarily assess the clinical utility of the intervention for PSA.

METHODS

This study comprises 3 phases. Phase 1 (completed) involved the development of a VR prototype targeting PSA, using multidisciplinary iterative input. Phase 2 (data collection completed) involves examining the feasibility aspects of the VR intervention. This randomized feasibility trial involves assessing the novel VR preoperative intervention compared to a VR control (ie, nature trek) condition and a treatment-as-usual group among patients undergoing breast cancer surgery. Phase 3 will involve refining the prototype based on feasibility findings and input from people with lived experience for a future clinical trial, using focus groups with participants from phase 2.

RESULTS

This study was funded in March 2019. Phase 1 was completed in April 2020. Phase 2 data collection was completed in January 2024 and data analysis is ongoing. Focus groups were completed in February 2024. Both the feasibility study and focus groups will contribute to further refinement of the initial VR prototype (phase 3), with the final simulation to be completed by mid-2024.

CONCLUSIONS

The findings from this work will contribute to the limited body of research examining feasible and broadly accessible interventions for PSA. Knowledge gained from this research will contribute to the final development of a novel VR intervention to be tested in a large population of patients with cancer before surgery in a randomized clinical trial.

Prehabilitation in Adults Undergoing Cancer Surgery: A Comprehensive Review on Rationale, Methodology, and Measures of Effectiveness

Cancer surgery places a significant burden on a patients' functional status and quality of life. In addition, cancer surgery is fraught with postoperative complications, themselves influenced by a patient's functional status. Prehabilitation is a unimodal or multimodal strategy that aims to increase a patient's functional capacity to reduce postoperative complications and improve postoperative recovery and quality of life. In most cases, it involves exercise, nutrition, and anxiety-reducing interventions. The impact of prehabilitation has been explored in several types of cancer surgery, most commonly colorectal and thoracic. Overall, the existing evidence suggests prehabilitation improves physiological outcomes (e.g., lean body mass, maximal oxygen consumption) as well as clinical outcomes (e.g., postoperative complications, quality of life). Notably, the benefit of prehabilitation is additional to that of enhanced recovery after surgery (ERAS) programs. While safe, prehabilitation programs require multidisciplinary coordination preoperatively. Despite the existence of numerous systematic reviews and meta-analyses, the certainty of evidence demonstrating the efficacy and safety of prehabilitation is low to moderate, principally due to significant methodological heterogeneity and small sample sizes. There is a need for more large-scale multicenter randomized controlled trials to draw strong clinical recommendations.

Perioperative mental health intervention for depression and anxiety symptoms in older adults study protocol: design and methods for three linked randomised controlled trials

INTRODUCTION

Preoperative anxiety and depression symptoms among older surgical patients are associated with poor postoperative outcomes, yet evidence-based interventions for anxiety and depression have not been applied within this setting. We present a protocol for randomised controlled trials (RCTs) in three surgical cohorts: cardiac, oncological and orthopaedic, investigating whether a perioperative mental health intervention, with psychological and pharmacological components, reduces perioperative symptoms of depression and anxiety in older surgical patients.

METHODS AND ANALYSIS

Adults ≥60 years undergoing cardiac, orthopaedic or oncological surgery will be enrolled in one of three-linked type 1 hybrid effectiveness/implementation RCTs that will be conducted in tandem with similar methods. In each trial, 100 participants will be randomised to a remotely delivered perioperative behavioural treatment incorporating principles of behavioural activation, compassion and care coordination, and medication optimisation, or enhanced usual care with mental health-related resources for this population. The primary outcome is change in depression and anxiety symptoms assessed with the Patient Health Questionnaire-Anxiety Depression Scale from baseline to 3 months post surgery. Other outcomes include quality of life, delirium, length of stay, falls, rehospitalisation, pain and implementation outcomes, including study and intervention reach, acceptability, feasibility and appropriateness, and patient experience with the intervention.

ETHICS AND DISSEMINATION

The trials have received ethics approval from the Washington University School of Medicine Institutional Review Board. Informed consent is required for participation in the trials. The results will be submitted for publication in peer-reviewed journals, presented at clinical research conferences and disseminated via the Center for Perioperative Mental Health website.

Outcome Heterogeneity in Prehabilitation Trials-Are We Comparing Apples and Oranges?

INTRODUCTION

Over the last decade, the number of prehabilitation randomised controlled trials (RCTs) has increased significantly. Therefore, this review aimed to describe the outcomes reported in prehabilitation RCTs in patients undergoing cancer surgery.

METHODS

A search was conducted in Embase, Allied and Complementary Medicine Database, The Cochrane Library, PsycINFO, MEDLINE, and Cumulated Index to Nursing and Allied Health Literature from inception to July 2021. We included RCTs evaluating the effectiveness of preoperative exercise, nutrition, and psychological interventions on postoperative complications and length of hospital stay in adult oncology patients who underwent thoracic and gastrointestinal cancer surgery. The verbatim outcomes reported in each article were extracted, and each outcome was assessed to determine whether it was defined and measured using a validated tool. Verbatim outcomes were grouped into standardized outcomes and categorized into domains. The quality of outcome reporting in each identified article was assessed using the Harman tool (score range 0-6, where 0 indicated the poorest quality).

RESULTS

A total of 74 RCTs were included, from which 601 verbatim outcomes were extracted. Only 110 (18.3%) of the verbatim outcomes were defined and 270 (44.9%) were labeled as either "primary" or "secondary" outcomes. Verbatim outcomes were categorized into 119 standardized outcomes and assigned into one of five domains (patient-reported outcomes, surgical outcomes, physical/functional outcomes, disease activity, and intervention delivery). Surgical outcomes were the most common outcomes reported (n = 71 trials, 95.9%). The overall quality of the reported outcomes was poor across trials (median score: 2.0 [IQR = 0.00-3.75]).

CONCLUSIONS

Prehabilitation RCTs display considerable heterogeneity in outcome reporting, and low outcome reporting quality. The development of standardized core outcome sets may help improve article quality and enhance the clinical utility of prehabilitation following cancer surgery.

Perioperative Care in Cardiac Surgery: A Joint Consensus Statement by the Enhanced Recovery After Surgery (ERAS) Cardiac Society, ERAS International Society, and The Society of Thoracic Surgeons (STS)

Enhanced Recovery After Surgery (ERAS) programs have been shown to lessen surgical insult, promote recovery, and improve postoperative clinical outcomes across a number of specialty operations. A core tenet of ERAS involves the provision of protocolized evidence-based perioperative interventions. Given both the growing enthusiasm for applying ERAS principles to cardiac surgery and the broad scope of relevant interventions, an international, multidisciplinary expert panel was assembled to derive a list of potential program elements, review the literature, and provide a statement regarding clinical practice for each topic area. This article summarizes those consensus statements and their accompanying evidence. These results provide the foundation for best practice for the management of the adult patient undergoing cardiac surgery.

Feasibility study of a multimodal prehabilitation programme in women receiving neoadjuvant therapy for breast cancer in a major cancer hospital: a protocol

INTRODUCTION

Neoadjuvant therapy has become a standard treatment for patients with stage II/III HER2 positive and triple negative breast cancer, and in well-selected patients with locally advanced and borderline resectable high risk, luminal B breast cancer. Side effects of neoadjuvant therapy, such as fatigue, cardiotoxicity, neurotoxicity, anxiety, insomnia, vasomotor symptoms, gastrointestinal disturbance as well as a raft of immune-related adverse events, may impact treatment tolerance, long-term outcomes, and quality of life. Providing early supportive care prior to surgery (typically termed 'prehabilitation') may mitigate these side effects and improve quality of life.During our codesign of the intervention, consumers and healthcare professionals expressed desire for a programme that 'packaged' care, was easy to access, and was embedded in their care pathway. We hypothesise that a multimodal supportive care programme including exercise and complementary therapies, underpinned by behavioural change theory will improve self-efficacy, quality of life, readiness for surgery and any additional treatment for women with breast cancer. We seek to explore cardiometabolic, residual cancer burden and surgical outcomes, along with chemotherapy completion (relative dose intensity). This article describes the protocol for a feasibility study of a multimodal prehabilitation programme.

METHODS AND ANALYSIS

This is a prospective, mixed-method, feasibility study of a multi-modal programme in a hospital setting for 20-30 women with breast cancer receiving neoadjuvant therapy. Primary outcomes are recruitment rate, retention rate, adherence and acceptability. Secondary outcomes include patient reported outcome measures (PROMs), surgical outcomes, length of stay, satisfaction with surgery, chemotherapy completion rates, changes in metabolic markers and adverse events. Interviews and focus groups to understand the experience with prehabilitation and different factors that may affect feasibility of the intervention . The output of this study will be a codesigned, evidence-informed intervention assessed for feasibility and acceptability by women with breast cancer and the healthcare professionals that care for them.

ETHICS AND DISSEMINATION

The study received ethics approval from the St Vincents Hospital HREC (HREC/2021/ETH12198). Trial results will be communicated to participants, healthcare professionals, and the public via publication and conferences.

Psychological Distress After Inpatient Noncardiac Surgery: A Secondary Analysis of the Measurement of Exercise Tolerance Before Surgery Prospective Cohort Study

OBJECTIVE

To describe the incidence and natural progression of psychological distress after major surgery.

BACKGROUND

The recovery process after surgery imposes physical and mental burdens that put patients at risk of psychological distress. Understanding the natural course of psychological distress after surgery is critical to supporting the timely and tailored management of high-risk individuals.

METHODS

We conducted a secondary analysis of the "Measurement of Exercise Tolerance before Surgery" multicentre cohort study (Canada, Australia, New Zealand, and the UK). Measurement of Exercise Tolerance before Surgery recruited adult participants (≥40 years) undergoing elective inpatient noncardiac surgery and followed them for 1 year. The primary outcome was the severity of psychological distress measured using the anxiety-depression item of EQ-5D-3L. We used cumulative link mixed models to characterize the time trajectory of psychological distress among relevant patient subgroups. We also explored potential predictors of severe and/or worsened psychological distress at 1 year using multivariable logistic regression models.

RESULTS

Of 1546 participants, moderate-to-severe psychological distress was reported by 32.6% of participants before surgery, 27.3% at 30 days after surgery, and 26.2% at 1 year after surgery. Psychological distress appeared to improve over time among females [odds ratio (OR): 0.80, 95% CI: 0.65-0.95] and patients undergoing orthopedic procedures (OR: 0.73, 95% CI: 0.55-0.91), but not among males (OR: 0.87, 95% CI: 0.87-1.07) or patients undergoing nonorthopedic procedures (OR: 0.95, 95% CI: 0.87-1.04). Among the average middle-aged adult, there were no time-related changes (OR: 0.94, 97% CI: 0.75-1.13), whereas the young-old (OR: 0.89, 95% CI: 0.79-0.99) and middle-old (OR: 0.87, 95% CI: 0.73-1.01) had small improvements. Predictors of severe and/or worsened psychological distress at 1 year were younger age, poor self-reported functional capacity, smoking history, and undergoing open surgery.

CONCLUSIONS

One-third of adults experience moderate to severe psychological distress before major elective noncardiac surgery. This distress tends to persist or worsen over time among select patient subgroups.

The effectiveness of prehabilitation interventions on biopsychosocial and service outcomes pre and post upper gastrointestinal surgery: a systematic review

PURPOSE

This review synthesised the evidence for the effect of prehabilitation interventions on biopsychosocial and service outcomes.

MATERIALS AND METHODS

A systematic review was conducted. 10 databases were searched to December 2023. Prospective experimental studies exploring prehabilitation interventions in adults undergoing upper gastrointestinal surgery were included. Prehabilitation was any preoperative intervention to improve physical or psychological outcomes. Included studies required a comparator group or alternative preoperative intervention as well as baseline, presurgical and postoperative assessment points. Study quality was assessed using the Cochrane risk of bias tool (v.2). Data synthesis was narrative (SWiM guidance).

RESULTS

6028 studies were screened, with 25 studies included. Prehabilitation interventions were: inspiratory muscle training (five studies n = 450); exercise (nine studies n = 683); psychological (one study n = 400); and nutritional (ten studies n = 487). High quality studies showed preoperative improvements in impairments directly targeted by the interventions. Generally, these did not translate into functional or postoperative improvements, but multimodal interventions were more promising.

CONCLUSION

Current evidence supports prehabilitation as safe to preserve or improve preoperative function. Heterogeneity in outcomes and variable study quality means definitive conclusions regarding interventions are not yet possible, limiting implementation. Agreement of clinical outcomes and cost effectiveness evaluation is required.

Multimodal prerehabilitation for elderly patients with sarcopenia in colorectal surgery

Sarcopenia, which is characterized by progressive and generalized loss of skeletal muscle mass and strength, has been well described to be associated with numerous poor postoperative outcomes, such as increased perioperative mortality, postoperative sepsis, prolonged length of stay, increased cost of care, decreased functional outcome, and poorer oncological outcomes in cancer surgery. Multimodal prehabilitation, as a concept that involves boosting and optimizing the preoperative condition of a patient prior to the upcoming stressors of a surgical procedure, has the purported benefits of reversing the effects of sarcopenia, shortening hospitalization, improving the rate of return to bowel activity, reducing the costs of hospitalization, and improving quality of life. This review aims to present the current literature surrounding the concept of sarcopenia, its implications pertaining to colorectal cancer and surgery, a summary of studied multimodal prehabilitation interventions, and potential future advances in the management of sarcopenia.

The Prehabilitation Radiotherapy Exercise, smoking Habit cessation and Balanced diet Study (PREHABS) protocol to explore the feasibility of embedding behavioural modifications into the clinical pathway for patients undergoing radical radiotherapy for lung cancer

Patients with curable non-surgical lung cancer are often current smokers, have co-existing medical comorbidities and are treated with curative radiotherapy. To maximise the benefits of modern radiotherapy, there is an urgent need to optimise the patient's health to improve survival and quality of life.

METHODS AND ANALYSIS

The Yorkshire Cancer Research-funded Prehabilitation Radiotherapy Exercise, smoking Habit cessation and Balanced diet Study (PREHABS) (L426) is a single-centre prospective feasibility study to assess embedding behavioural changes into the radical radiotherapy pathway of patients with lung cancer. Feasibility will be assessed by measuring acceptability, demand and implementation. The duration of the study is 24 months. PREHABS has two workstreams: the intervention study and the theory of change (ToC) study.Intervention study: PREHABS will commence at the R-IDEAL phase 2 trial (exploratory) based on existing evidence and includes support for smoking cessation, increasing activity and dietary well-being. Patients undergoing radical radiotherapy for lung cancer will be recruited from the oncology department at Leeds Teaching Hospitals NHS Trust (LTHT). ToC study: to maximise the acceptability and adherence to the PREHABS, we will use a ToC approach to qualitatively explore the key barriers and enablers of implementing a tailored programme of 'prehabilitation'. The PREHABS ToC study participants will be recruited from patients with lung cancer undergoing radical radiotherapy and staff from the LTHT oncology department.

ANALYSIS

The primary endpoint analysis will report the number of participants and adherence to the study interventions. Secondary endpoints include continued engagement with study interventions post-treatment. The analysis will focus on descriptive statistics. Thematic analysis of the qualitative data from the ToC study will identify consensus on intervention optimisation and delivery.

ETHICS AND DISSEMINATION

On 12 May 2021, the Cambridge East Ethics Committee granted ethical approval (21/EE/0048). The study is registered in the National Institute for Health and Care Research (NIHR) portfolio. The results will be disseminated through publication in peer-reviewed scientific journals and presented at conferences.

Preparing for and Not Waiting for Surgery

Cancer surgery is an essential treatment strategy but can disrupt patients' physical and psychological health. With worldwide demand for surgery expected to increase, this review aims to raise awareness of this global public health concern, present a stepwise framework for preoperative risk evaluation, and propose the adoption of personalised prehabilitation to mitigate risk. Perioperative medicine is a growing speciality that aims to improve clinical outcome by preparing patients for the stress associated with surgery. Preparation should begin at contemplation of surgery, with universal screening for established risk factors, physical fitness, nutritional status, psychological health, and, where applicable, frailty and cognitive function. Patients at risk should undergo a formal assessment with a qualified healthcare professional which informs meaningful shared decision-making discussion and personalised prehabilitation prescription incorporating, where indicated, exercise, nutrition, psychological support, 'surgery schools', and referral to existing local services. The foundational principles of prehabilitation can be adapted to local context, culture, and population. Clinical services should be co-designed with all stakeholders, including patient representatives, and require careful mapping of patient pathways and use of multi-disciplinary professional input. Future research should optimise prehabilitation interventions, adopting standardised outcome measures and robust health economic evaluation.

Preoperative Virtual Reality to Expose Patients With Breast Cancer to the Operating Room Environment: Feasibility and Pilot Case Series Study

BACKGROUND

Clinically elevated preoperative distress and anxiety are common among patients undergoing cancer surgery. Preoperative interventions have been developed to mitigate this distress and anxiety but are inconsistent in efficacy and feasibility for broad implementation.

OBJECTIVE

This preliminary pilot study aims to assess the feasibility and utility of a newly developed virtual reality (VR) intervention to expose patients awaiting breast cancer surgery to the operating room environment and a simulation of anesthetic induction.

METHODS

Patients undergoing breast cancer surgery (N=7) were assigned to the VR intervention or control (treatment as usual) group and completed self-report measures of distress and anxiety before surgery, on the day of surgery, and after surgery (5 and 30 d postoperatively). Those in the intervention group trialed the VR simulation 1 to 2 weeks preoperatively and provided qualitative and quantitative feedback. We assessed the feasibility of recruitment capability and study design and evaluated participants' impressions of the intervention using self-report rating scales and open-ended questions. We also descriptively examined distress and anxiety levels throughout the duration of the study.

RESULTS

Recruitment occurred between December 2021 and December 2022 and progressed slowly (rate: 1 participant/7 wk on average; some hesitancy because of stress and being overwhelmed). All participants who consented to participate completed the entire study. All participants were female and aged 56 (SD 10.56) years on average. In total, 57% (4/7) of the participants were assigned to the intervention group. On average, intervention participants spent 12 minutes engaged in the VR simulation. In general, the intervention was rated favorably (eg, clear information, enjoyable, and attractive presentation; mean% agreement 95.00-96.25, SD 4.79-10.00) and as helpful (mean% agreement 87.50, SD 25.00). Participants described the intervention as realistic (eg, "It was realistic to my past surgical experiences"), impacting their degree of preparedness and expectations for surgery (eg, "The sounds and sights and procedures give you a test run; they prepare you for the actual day"), and having a calming or relaxing effect (eg, "You feel more relaxed for the surgery").

CONCLUSIONS

This preoperative VR intervention demonstrated preliminary feasibility among a sample of patients undergoing breast cancer surgery. Results and participant feedback will inform modifications to the VR intervention and the study design of a large-scale randomized controlled trial to examine the efficacy of this intervention.

Neo-train: study protocol and feasibility results for a two-arm randomized controlled trial investigating the effect of supervised exercise during neoadjuvant chemotherapy on tumour response in patients with breast cancer

BACKGROUND

Prehabilitation with exercise interventions during neoadjuvant chemotherapy (NACT) is effective in reducing physical and psychosocial chemotherapy-related adverse events in patients with cancer. In preclinical studies, data also support a growth inhibitory effect of aerobic exercise on the tumour microenvironment with possible improved chemotherapy delivery but evidence in human patients is limited. The aim of the study here described is to investigate if supervised exercise with high-intensity aerobic and resistance training during NACT can improve tumour reduction in patients with breast cancer.

METHODS

This parallel two-armed randomized controlled trial is planned to include 120 women aged ≥ 18 years with newly diagnosed breast cancer starting standard NACT at a university hospital in Denmark (a total of 90 participants needed according to the power calculation and allowing 25% (n = 30) dropout). The participants will be randomized to usual care or supervised exercise consisting of high-intensity interval training on a stationary exercise bike and machine-based progressive resistance training offered three times a week for 24 weeks during NACT, and screening-based advice to seek counselling in case of moderate-severe psychological distress (Neo-Train program). The primary outcome is tumour size change (maximum diameter of the largest lesion in millimetre) measured by magnetic resonance imaging prior to surgery. Secondary outcomes include clinical/pathological, physical and patient-reported measures such as relative dose intensity of NACT, hospital admissions, body composition, physical fitness, muscle strength, health-related quality of life, general anxiety, depression, and biological measures such as intratumoural vascularity, tumour infiltrating lymphocytes, circulating tumour DNA and blood chemistry. Outcomes will be measured at baseline (one week before to 1-2 weeks after starting NACT), during NACT (approximately week 7, 13 and 19), pre-surgery (approximately week 21-29), at surgery (approximately week 21-30) and 3 months post-surgery (approximately 33-42 weeks from baseline).

DISCUSSION

This study will provide novel and important data on the potential benefits of supervised aerobic and resistance exercise concomitant to NACT on tumour response and the tumour microenvironment in patients with breast cancer, with potential importance for survival and risk of recurrence. If effective, our study may help increase focus of exercise as an active part of the neoadjuvant treatment strategy.

The effect of preoperative behaviour change interventions on pre- and post-surgery health behaviours, health outcomes, and health inequalities in adults: A systematic review and meta-analyses

BACKGROUND

Prehabilitation interventions are being delivered across surgical specialities to improve health risk behaviours leading to better surgical outcomes and potentially reduce length of hospital stay. Most previous research has focused on specific surgery specialities and has not considered the impact of interventions on health inequalities, nor whether prehabilitation improves health behaviour risk profiles beyond surgery. The aim of this review was to examine behavioural Prehabilitation interventions across surgeries to inform policy makers and commissioners of the best available evidence.

METHODS AND FINDINGS

A systematic review and meta-analysis of randomised controlled trials (RCTs) was conducted to determine the effect of behavioural prehabilitation interventions targeting at least one of: smoking behaviour, alcohol use, physical activity, dietary intake (including weight loss interventions) on pre- and post-surgery health behaviours, health outcomes, and health inequalities. The comparator was usual care or no treatment. MEDLINE, PubMed, PsychINFO, CINAHL, Web of Science, Google Scholar, Clinical trials and Embase databases were searched from inception to May 2021, and the MEDLINE search was updated twice, most recently in March 2023. Two reviewers independently identified eligible studies, extracted data, and assessed risk of bias using the Cochrane risk of bias tool. Outcomes were length of stay, six-minute walk test, behaviours (smoking, diet, physical activity, weight change, and alcohol), and quality of life. Sixty-seven trials were included; 49 interventions targeted a single behaviour and 18 targeted multiple behaviours. No trials examined effects by equality measures. Length of stay in the intervention group was 1.5 days shorter than the comparator (n = 9 trials, 95% CI -2.6 to -0.4, p = 0.01, I2 83%), although in sensitivity analysis prehabilitation had the most impact in lung cancer patients (-3.5 days). Pre-surgery, there was a mean difference of 31.8 m in the six-minute walk test favouring the prehabilitation group (n = 19 trials, 95% CI 21.2 to 42.4m, I2 55%, P <0.001) and this was sustained to 4-weeks post-surgery (n = 9 trials, mean difference = 34.4m (95%CI 12.8 to 56.0, I2 72%, P = 0.002)). Smoking cessation was greater in the prehabilitation group before surgery (RR 2.9, 95% CI 1.7 to 4.8, I2 84%), and this was sustained at 12 months post-surgery (RR 1.74 (95% CI 1.20 to 2.55, I2 43%, Tau2 0.09, p = 0.004)There was no difference in pre-surgery quality of life (n = 12 trials) or BMI (n = 4 trials).

CONCLUSIONS

Behavioural prehabilitation interventions reduced length of stay by 1.5 days, although in sensitivity analysis the difference was only found for Prehabilitation interventions for lung cancer. Prehabilitation can improve functional capacity and smoking outcomes just before surgery. That improvements in smoking outcomes were sustained at 12-months post-surgery suggests that the surgical encounter holds promise as a teachable moment for longer-term behavioural change. Given the paucity of data on the effects on other behavioural risk factors, more research grounded in behavioural science and with longer-term follow-up is needed to further investigate this potential.

Group psychological intervention for emotional distress in haematopoietic stem cell transplantation: A feasibility randomised clinical trial

PURPOSE

Haematopoietic stem cell transplantation (HSCT) is an intensive procedure associated with elevated psychological distress, particularly during the initial stages. Based on self-regulatory theory, a prophylactic group intervention was developed to mitigate this distress by targeting perceptions of HSCT and coping. This study evaluated the feasibility of delivering the intervention and of conducting a randomised clinical trial to assess efficacy.

METHODS

Adults from consecutive referrals at two transplant centres were randomised to the intervention or to treatment as usual at each site. Psychological distress (primary outcome), HSCT perceptions, and coping were assessed at baseline, on transplant day, and two and four weeks after transplantation.

RESULTS

Of 99 eligible patients, 45 consented. Main barriers to consent were insufficient time prior to transplantation, competing priorities, being unwell, and travel distance. Of 21 participants randomised to the intervention, five attended. Main barriers to attendance included insufficient time prior to transplantation and having competing priorities. Groups could not be held sufficiently frequently to enable attendance prior to transplantation, as randomising participants to the control group limited accrual. Anxiety peaked two weeks following transplantation. Depression increased throughout the acute phase. Clinical levels of distress were observed in 42% of patients during HSCT. Intervention effects were small but sample sizes for a full trial appeared feasible.

CONCLUSIONS

Multimodal prehabilitation is required but there are specific barriers to delivering a group-based intervention and conducting a trial. Group prehabilitation requires customisation and better integration with routine care, such as patient screening, personalisation, and options for remote delivery.

Benefits of Prehabilitation before Complex Aortic Surgery

The purpose of this narrative review was to detail and discuss the underlying principles and benefits of preoperative interventions addressing risk factors for perioperative adverse events in open aortic surgery (OAS). The term "complex aortic disease" encompasses juxta/pararenal aortic and thoraco-abdominal aneurysms, chronic aortic dissection and occlusive aorto-iliac pathology. Although endovascular surgery has been increasingly favored, OAS remains a durable option, but by necessity involves extensive surgical approaches and aortic cross-clamping and requires a trained multidisciplinary team. The physiological stress of OAS in a fragile and comorbid patient group mandates thoughtful preoperative risk assessment and the implementation of measures dedicated to improving outcomes. Cardiac and pulmonary complications are one of the most frequent adverse events following major OAS and their incidences are correlated to the patient's functional status and previous comorbidities. Prehabilitation should be considered in patients with risk factors for pulmonary complications including advanced age, previous chronic obstructive pulmonary disease, and congestive heart failure with the aid of pulmonary function tests. It should also be combined with other measures to improve postoperative course and be included in the more general concept of enhanced recovery after surgery (ERAS). Although the current level of evidence regarding the effectiveness of ERAS in the setting of OAS remains low, an increasing body of literature has promoted its implementation in other specialties. Consequently, vascular teams should commit to improving the current evidence through studies to make ERAS the standard of care for OAS.

Postoperative effect of sufentanil preemptive analgesia combined with psychological intervention on breast cancer patients

OBJECTIVES

To explore the postoperative effects of sufentanil preemptive analgesia combined with psychological intervention on breast cancer patients undergoing radical surgery.

METHODS

112 female breast cancer patients aged 18-80 years old who underwent radical surgery by the same surgeon were randomly divided into 4 groups, and there were 28 patients in each group. Patients in group A were given 10 µg sufentanil preemptive analgesia combined with perioperative psychological support therapy (PPST), group B had only 10 µg sufentanil preemptive analgesia, group C had only PPST, and group D were under general anesthesia with conventional intubation. Visual analogue scoring (VAS) was used for analgesic evaluation at 2, 12 and 24 h after surgery and compared among the four groups by ANOVA method.

RESULTS

The awakening time of patients in group A or B was significantly shorter than that in group C or D, and the awakening time in group C was significantly shorter than that in group D. Moreover, patients in group A had the shortest extubation time, while the group D had the longest extubation time. The VAS scores at different time points showed significant difference, and the VAS scores at 12 and 24 h were significantly lower than those at 2 h (P < 0.05). The VAS scores and the changing trend of VAS scores were varied among the four groups (P < 0.05). In addition, we also found that patients in group A had the longest time to use the first pain medication after surgery, while patients in group D had the shortest time. But the adverse reactions among the four groups showed no difference.

CONCLUSIONS

Sufentanil preemptive analgesia combined with psychological intervention can effectively relieve the postoperative pain of breast cancer patients.

Prehabilitation versus no prehabilitation to improve functional capacity, reduce postoperative complications and improve quality of life in colorectal cancer surgery

BACKGROUND

Surgery is the cornerstone in curative treatment of colorectal cancer. Unfortunately, surgery itself can adversely affect patient health. 'Enhanced Recovery After Surgery' programmes, which include multimodal interventions, have improved patient outcomes substantially. However, these are mainly applied peri- and postoperatively. Multimodal prehabilitation includes multiple preoperative interventions to prepare patients for surgery with the aim of increasing resilience, thereby improving postoperative outcomes.

OBJECTIVES

To determine the effects of multimodal prehabilitation programmes on functional capacity, postoperative complications, and quality of life in adult patients undergoing surgery for colorectal cancer.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase and PsycINFO in January 2021. We also searched trial registries up to March 2021.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) in adult patients with non-metastatic colorectal cancer, scheduled for surgery, comparing multimodal prehabilitation programmes (defined as comprising at least two preoperative interventions) with no prehabilitation. We focused on the following outcomes: functional capacity (i.e. 6-minute walk test, VO2peak, handgrip strength), postoperative outcomes (i.e. complications, mortality, length of hospital stay, emergency department visits, re-admissions), health-related quality of life, compliance, safety of prehabilitation, and return to normal activities.

DATA COLLECTION AND ANALYSIS

Two authors independently selected studies, extracted data, assessed risk of bias and used GRADE to assess the certainty of the evidence. Any disagreements were solved with discussion and consensus. We pooled data to perform meta-analyses, where possible.

MAIN RESULTS

We included three RCTs that enrolled 250 participants with non-metastatic colorectal cancer, scheduled for elective (mainly laparoscopic) surgery. Included trials were conducted in tertiary care centres and recruited patients during periods ranging from 17 months to 45 months. A total of 130 participants enrolled in a preoperative four-week trimodal prehabilitation programme consisting of exercise, nutritional intervention, and anxiety reduction techniques. Outcomes of these participants were compared to those of 120 participants who started an identical but postoperative programme. Postoperatively, prehabilitation may improve functional capacity, determined with the 6-minute walk test at four and eight weeks (mean difference (MD) 26.02, 95% confidence interval (CI) -13.81 to 65.85; 2 studies; n = 131; and MD 26.58, 95% CI -8.88 to 62.04; 2 studies; n = 140); however, the certainty of evidence is low and very low, respectively, due to serious risk of bias, imprecision, and inconsistency. After prehabilitation, the functional capacity before surgery improved, with a clinically relevant mean difference of 24.91 metres (95% CI 11.24 to 38.57; 3 studies; n = 225). The certainty of evidence was moderate due to downgrading for serious risk of bias. The effects of prehabilitation on the number of complications (RR 0.95, 95% CI 0.70 to 1.29; 3 studies; n = 250), emergency department visits (RR 0.72, 95% CI 0.39 to 1.32; 3 studies; n = 250) and re-admissions (RR 1.20, 95% CI 0.54 to 2.65; 3 studies; n = 250) were small or even trivial. The certainty of evidence was low due to downgrading for serious risk of bias and imprecision. The effects on VO2peak, handgrip strength, length of hospital stay, mortality rate, health-related quality of life, return to normal activities, safety of the programme, and compliance rate could not be analysed quantitatively due to missing or insufficient data. The included studies did not report a difference between groups for health-related quality of life and length of hospital stay. Data on remaining outcomes were not reported or were reported inadequately in the included studies.

AUTHORS' CONCLUSIONS

Prehabilitation may result in an improved functional capacity, determined with the 6-minute walk test both preoperatively and postoperatively. A solid effect on the number of omplications, postoperative emergency department visits and re-admissions could not be established. The certainty of evidence ranges from moderate to very low, due to downgrading for serious risk of bias, imprecision and inconsistency. In addition, only three heterogeneous studies were included in this review. Therefore, the findings of this review should be interpreted with caution. Numerous relevant RCTs are ongoing and will be included in a future update of this review.

Systematic review with meta-analysis: Current and emerging models of preoperative psychological preparation for individuals undergoing stoma surgery

OBJECTIVE

Stoma surgery is a profoundly life changing event that can result in a range of negative psychological and mental health outcomes, often requiring significant postoperative adaption. While postoperative avenues of support to address these outcomes exist, there remains a lack of preoperative psychological preparation for surgical candidates in standard models of care. The present systematic review and meta-analysis aims to examine the current and emerging models of psychological preparation available to stoma surgery candidates during the preoperative period.

METHODS

A systematic search of PubMed, Embase, Emcare, PsycINFO, CINAHL, and SCOPUS was conducted. All studies examining the effects of preoperative psychological interventions targeting postoperative psychological adjustment and/or mental health outcomes for individuals planning to undergo or who had undergone stoma surgery were included.

RESULTS

Overall, 15 publications meeting inclusion criteria were identified, encompassing 1565 total participants. Intervention types ranged from psychoeducational, counselling, and practical based skills, examining the postoperative outcomes of anxiety, depression, quality of life, adjustment, self-efficacy, and systematic improvements to standard models of care. Five studies examining postoperative anxiety were included for meta-analysis, demonstrating an overall significant effect (SMD = -1.13, 95% CI -1.96 to -0.30, p = .008). Due to the high level of heterogeneity between remaining studies, articles examining postoperative outcomes other than anxiety were synthesised in narrative form.

CONCLUSION

Despite some promising advancements in the field, there remains insufficient evidence to judge the overall effectiveness of current and emerging models of preoperative psychological preparation on postoperative psychological outcomes for individuals facing stoma surgery.

Effect of short-term prehabilitation of older patients with colorectal cancer: A propensity score-matched analysis

Objective

The aim of this study was to assess the impact of short-term, hospital-based, supervised multimodal prehabilitation on elderly patients with colorectal cancer.

Methods

A single-center, retrospective study was conducted from October 2020 to December 2021, which included a total of 587 CRC patients who were scheduled to undergo radical resection. A propensity score-matching analysis was performed to reduce selection bias. All patients were treated within a standardized enhanced recovery pathway, and patients in the prehabilitation group received an additional supervised, short-term multimodal preoperative prehabilitation intervention. Short-term outcomes were compared between the two groups.

Results

Among the participants, 62 patients were excluded; 95 participants were included in the prehabilitation group and 430 in the non-prehabilitation group. After PSM analysis, 95 pairs of well-matched patients were included in the comparative study. Participants in the prehabilitation group had better preoperative functional capacity (402.78 m vs. 390.09 m, P<0.001), preoperative anxiety status (9% vs. 28%, P<0.001), time to first ambulation[25.0(8.0) hours vs. 28.0(12.4) hours, P=0.008], time to first flatus [39.0(22.0) hours vs. 47.7(34.0) hours, P=0.006], duration of the postoperative length of hospital stay [8.0(3.0) days vs. 10.0(5.0) days, P=0.007), and quality of life in terms of psychological dimensions at 1 month postoperatively [53.0(8.0) vs. 49.0(5.0), P<0.001].

Conclusion

The short-term, hospital-based, supervised multimodal prehabilitation is feasible with a high degree of compliance in older CRC patients, which improves their short-term clinical outcomes.

The impact of prehabilitation interventions on affective and functional outcomes for young to midlife adult cancer patients: A systematic review

OBJECTIVE

Cancer remains one of the most enduring health crises of the modern world. Prehabilitation is a relatively new intervention aimed at preparing individuals for the stresses associated with treatment from diagnosis. Prehabilitation can include exercise, psychological and nutrition-based interventions. The present systematic review aimed to assess the efficacy of prehabilitation on affective and functional outcomes for young to midlife adult cancer patients (18-55 years). Outcomes of interest included prehabilitation programme composition, duration, mode of delivery and measures used to determine impact on affective and functional outcomes.

METHODS

The following databases were searched with controlled and free text vocabulary; Psychological Information database (PsychINFO), Culmunated Index to Nursing and Allied Health Literature (CINAHL), Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica Database (EMBASE) and Public MEDLINE (PubMed). Abstract and full-text screening was conducted with a secondary reviewer and final texts were subject to risk of bias analysis.

RESULTS

Thirteen texts were included at full-text. These included data of 797 prehabilitation participants (mean age 53 years) and a large representation of female participants (71% average). Evidence was found for the efficacy of psychological prehabilitation for anxiety reduction. Prehabilitation did not significantly affect health related quality of life. Findings moderately supported the therapeutic validity of exercise prehabilitation for functional outcomes, both in terms of clinical and experimental improvement with respect to the quality of evidence. Variation between all prehabilitation types was observed. There was insufficient evidence to support the efficacy of psychological prehabilitation on stress, distress or depression.

CONCLUSION

Implications for future research are highlighted and then discussed with respect to this young to midlife age group.

The effect of the preoperational psychoeducation program for Taiwanese breast cancer patients: A three-month follow-up study

Objective

Studies suggest that psychosocial interventions might be more effective during highly stressful periods, such as before surgery. This study aimed to explore the effectiveness of the Preoperational Health Psychology Education program among Taiwanese breast cancer patients.

Methods

A total of 137 adult women (1) diagnosed with breast cancer; and (2) admitted to the ward for surgery were recruited to join the program one day before surgery. Emotional distress, worries, and cancer self-efficacy were evaluated at admission, post-program, and 3-month post-surgery. Patients were grouped into high/low distress groups, and mixed-design ANOVA was used to examine the program's effectiveness.

Results

The results showed significant interactions of Group × Time in emotional distress (F = 16.15, p = .000) and worry (F = 5.81, p = .005), but not in self-efficacy (F = 2.97, p = .068). The post-hoc tests revealed significant decreases in emotional distress and worry in the high distress group.

Conclusion

The program was found helpful in reducing emotional distress and worries. The effect lasting for three-month for those with higher preoperational emotional distresses.

Innovation

This psycho-education program with a relatively rare one-session design, targeted at a less-studied pre-surgery period, is helpful to a less-studied population, Asian cancer patients.

Perspectives on the Direction of Cancer Prehabilitation in the Pandemic and Beyond

Growing attention has been placed on cancer prehabilitation in the recent years as the number of publications increase. The real-world application of prehabilitation remains heterogeneous and its implementation has been challenging during the COVID-19 pandemic. However, the pandemic has also provided impetus for change-leveraging technology and digitalization. This paper will discuss the pre-existing models of care, adaptations that had taken place in the pandemic, the model of care in the author's institution, and the future direction of cancer prehabilitation.

Patient Perspectives on Medical Trauma Related to Inflammatory Bowel Disease

Post-traumatic stress symptoms (PTSS) in response to medical trauma are understudied in inflammatory bowel disease (IBD). Two studies identify surgery, hospitalizations, and disease severity as risk factors. We aimed to document IBD-related patient experiences and how these relate to PTSS via a qualitative study. Adult patients with confirmed IBD recruited from two gastroenterology clinics underwent a semi-structured interview with a psychologist and completed the Post Traumatic Stress Disorder Symptom Scale for DSM5 (PSSI-5). Interviews were analyzed using an interpretive phenomenological approach. Themes and subthemes with representative quotations were documented based on thematic saturation. 16 participants, five met PSSI-5 criteria for PTSD. Five themes emerged: disease uncertainty, information exchange/quality, medical procedures, surgery, and coping. Patients with IBD may experience medical PTSS from several sources. Information, communication, and trust in clinicians is vital but may be sub-optimal. Both adaptive and maladaptive coping strategies are used to mitigate PTSS.

Coping Skills for Oncology Patients: A Practical Guide

OBJECTIVE

To present a practical how-to guide on implementing a coping skills intervention for patients with cancer facing surgery.

DATA SOURCES

A review of the literature on coping and coping skills and on assessing the impact on patients' emotional status.

CONCLUSION

Developing and presenting a brief coping skills program is possible within the confines of perioperative preparation for oncology patients. Such coping skills help develop a sense of self-efficacy, personal control, and resilience. Patients are responsive to the program and seem to practice their home assignments in a satisfactory manner.

IMPLICATIONS FOR NURSING PRACTICE

Oncology nurses can implement some of or all of the program with their patients. The coping skills fall under the mandate of a variety of health care professionals and are readily available to present to patients. The preoperative period is a suitable time to engage patients to learn coping skills.

Prehabilitation in high-risk patients scheduled for major abdominal cancer surgery: a feasibility study

Background

Patients presenting for major surgery with low cardiorespiratory fitness (deconditioning) and other modifiable risk factors are at increased risk of postoperative complications. This study investigated the feasibility of delivering prehabilitation in high-risk patients scheduled for major abdominal cancer surgery.

Methods

Eligible patients in this single-center cohort study included patients with poor fitness (objectively assessed by cardiopulmonary exercise testing, CPET) scheduled for elective major abdominal cancer surgery. Patients were recruited to participate in a prehabilitation program that spanned up to 6 weeks pre-operatively and comprised aerobic and resistance exercise training, breathing exercise, and nutritional support. The primary outcome assessed pre-specified feasibility targets: recruitment >70%, retention >85%, and intervention adherence >70%. Secondary outcomes were assessed for improved pre-operative functional status and health-related quality of life and for postoperative complications.

Results

Eighty-two (34%) out of 238 patients screened between April 2018 and December 2019 were eligible for recruitment. Fifty (61%) patients (52% males) with a median age of 71 (IQR, 63–77) years participated in the study. Baseline oxygen consumption the at anaerobic threshold and at peak exercise (mean±SD: 9.8±1.8 and 14.0±2.9 mL/kg/min, respectively) confirmed the deconditioned state of the study cohort. The retention rate within the prehabilitation program was 84%, with 42 participants returning for repeat CPET testing. While >60% of participants preferred to do home-based prehabilitation, adherence to the intervention was low—with only 12 (28%) and 15 (35%) of patients having self-reported compliance >70% with their exercise prescriptions.

Conclusion

Our prehabilitation program in high-risk cancer surgery patients did not achieve pre-specified targets for recruitment, retention, and self-reported program adherence. These findings underpin the importance of implementation research and strategies for the prehabilitation programs in major surgery.

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.

Prehabilitation. An Interdisciplinary Patient-Centric Conceptual Framework

OBJECTIVES

To review the recent literature around patient-centric prehabilitation in oncology patients and propose a conceptual framework to inform development of interdisciplinary prehabilitation services leading to focused, individualized prehabilitation interventions.

DATA SOURCES

A review of recent peer-reviewed literature, national guidance, and government strategy on prehabilitation in oncology patients.

CONCLUSION

Patient- centric prehabilitation is key to improving patient's experiences of cancer throughout the cancer journey while improving population health and reducing financial costs. Successful personalized prehabilitation interventions are comprised of an interplay between individual interdisciplinary roles, as illustrated in the conceptual framework. The role of the nurse underpins this whole process in patient screening, assessment, implementation of the intervention, and patient reassessment, ensuring care is dynamic and tailored to patient need.

IMPLICATIONS FOR NURSING PRACTICE

The review has discussed the key role that nurses play in the process but warrants more research in the area. The conceptual framework provides a basis to develop interdisciplinary prehabilitation services underpinned by the nurse's role. The review advocates the use of educational interventions to equip all health professionals with prehabilitation knowledge to enable interdisciplinary prehabilitation services to be developed.

The Wessex Fit-4-Cancer Surgery Trial (WesFit): a protocol for a factorial-design, pragmatic randomised-controlled trial investigating the effects of a multi-modal prehabilitation programme in patients undergoing elective major intra–cavity cancer surgery

Background: Surgical resection remains the primary curative treatment for intra-cavity cancer. Low physical fitness and psychological factors such as depression are predictive of post–operative morbidity, mortality and length of hospital stay. Prolonged post-operative morbidity is associated with persistently elevated risk of premature death. We aim to investigate whether a structured, responsive exercise training programme, a psychological support programme or combined exercise and psychological support, delivered between treatment decision and major intra-cavity surgery for cancer, can reduce length of hospital stay, compared with standard care.

Methods: WesFit is a pragmatic , 2x2 factorial-design, multi-centre, randomised-controlled trial, with planned recruitment of N=1560. Participants will be randomised to one of four groups. Group 1 (control) will receive usual pre-operative care, Group 2 (exercise) patients will undergo 2/3 aerobic, high-intensity interval training sessions per week supervised by personal trainers. Group 3 (psychological support) patients are offered 1 session per week at a local cancer support centre. Group 4 will receive both exercise and psychological support. All patients undergo baseline and pre-operative cardiopulmonary exercise testing, complete self-report questionnaires and will be followed up at 30 days, 12 weeks and 12 months post-operatively. Primary outcome is post-operative length-of-stay. Secondary outcomes include disability-adjusted survival at 1-year postoperatively, post-operative morbidity, and health-related quality of life. Exploratory investigations include objectively measured changes in physical fitness assessed by cardiopulmonary exercise test, disease-free and overall mortality at 1-year postoperatively, longer-term physical activity behaviour change, pre-operative radiological tumour regression, pathological tumour regression, pre and post-operative body composition analysis, health economics analysis and nutritional characterisation and its relationship to post-operative outcome.

Conclusions: The WesFit trial will be a randomised controlled study investigating whether a high-intensity exercise training programme +/- psychological intervention results in improvements in clinical and patient reported outcomes in patients undergoing major inter-cavity resection of cancer.

A randomised pilot trial of virtual reality-based relaxation for enhancement of perioperative well-being, mood and quality of life

A cancer diagnosis and subsequent treatment can trigger distress, negatively impact coping resources, and affect well-being as well as quality of life. The aim of this pilot study was to investigate feasibility and clinical effects of a VR intervention on quality of life, well-being and mood in cancer patients undergoing surgery compared to a non-VR intervention and a control group. 54 patients with colorectal cancer or liver metastases from colorectal cancer undergoing elective curatively intended surgery were recruited and randomised to one of two intervention groups or a control group receiving standard treatment. Participants assigned to one of the intervention groups either received a VR-based intervention twice daily or listened to music twice daily. Adherence to the intervention was 64.6% in the music group and 81.6% in the VR group. The VR intervention significantly reduced heart rate (- 1.2 bpm; 95% CI - 2.24 to - 0.22; p = 0.02) and respiratory rate (- 0.7 brpm; 95% CI - 1.08 to - 0.25; p = 0.01). Self-reported overall mood improved in both groups (VR: + 0.79 pts; 95% CI 0.37-1.21; p = 0.001; music: + 0.59 pts; 95% CI 0.22-0.97; p = 0.004). There was no difference in quality of life between the three groups. Both interventions groups reported changes in feelings. Adherence rates favoured the VR intervention over the music group. Observed clinical outcomes showed stronger intragroup effects on mood, feelings, and vital signs in the VR group. The study demonstrated feasibility of a VR intervention in cancer patients undergoing surgery and should encourage further research investigating the potential of VR interventions to positively influence well-being and mood in cancer patients.

Impact of Mental Health on General Surgery Patients and Strategies to Improve Outcomes

Mental Health Disorders (MHD) are a growing concern nationwide. The significant impact MHD have on surgical outcomes has only recently started to be understood. This literature review investigated how mental health impacts the outcomes of general surgery patients and what can be done to make improvements. Patients with schizophrenia had the poorest surgical outcomes. Mental health disorders increased post-surgical pain, hospital length of stay, complications, readmissions, and mortality. Mental health disorders decreased wound healing and quality of care. Optimizing outcomes will be best accomplished through integrating more effective perioperative screening tools and interventions. Screenings tools can incorporate artificial intelligence, MHD data, resilience and its biomarkers, and patient mental health questionnaires. Interventions include cognitive behavioral therapy, virtual reality, spirituality, pharmacology, and resilience training.

Clinical covariates that improve surgical risk prediction and guide targeted prehabilitation: an exploratory, retrospective cohort study of major colorectal cancer surgery patients evaluated with preoperative cardiopulmonary exercise testing

BACKGROUND

Preoperative risk stratification is used to derive an optimal treatment plan for patients requiring cancer surgery. Patients with reversible risk factors are candidates for prehabilitation programmes. This pilot study explores the impact of preoperative covariates of comorbid disease (Charlson Co-morbidity Index), preoperative serum biomarkers, and traditional cardiopulmonary exercise testing (CPET)-derived parameters of functional capacity on postoperative outcomes after major colorectal cancer surgery.

METHODS

Consecutive patients who underwent CPET prior to colorectal cancer surgery over a 2-year period were identified and a minimum of 2-year postoperative follow-up was performed. Postoperative assessment included: Clavien-Dindo complication score, Comprehensive Complication Index, Days at Home within 90 days (DAH-90) after surgery, and overall survival.

RESULTS

The Charlson Co-morbidity Index did not discriminate postoperative complications, or overall survival. In contrast, low preoperative haemoglobin, low albumin, or high neutrophil count were associated with postoperative complications and reduced overall survival. CPET-derived parameters predictive of postoperative complications, DAH-90, and reduced overall survival included measures of VCO₂ kinetics at anaerobic threshold (AT), peakVO₂ (corrected to body surface area), and VO₂ kinetics during the post-exercise recovery phase. Inflammatory parameters and CO₂ kinetics added significant predictive value to peakVO₂ within bi-variable models for postoperative complications and overall survival (P < 0.0001).

CONCLUSION

Consideration of modifiable 'triple low' preoperative risk (anaemia, malnutrition, deconditioning) factors and inflammation will improve surgical risk prediction and guide prehabilitation. Gas exchange parameters that focus on VCO₂ kinetics at AT and correcting peakVO₂ to body surface area (rather than absolute weight) may improve CPET-derived preoperative risk assessment.

Perioperative Risk Stratification and Modification

This article discusses the important topic of perioperative risk stratification and the interventions that can be used in the perioperative period for risk modification. It begins with a brief overview of the commonly used scoring systems, risk-prediction models, and assessments of functional capacity and discusses some of the evidence behind each. It then moves on to examine how perioperative risk can be modified through the use of shared decision making, management of multimorbidity, and prehabilitation programs, before considering what the future of risk stratification and modification may hold.

Prehabilitation versus no prehabilitation to improve functional capacity, reduce postoperative complications and improve quality of life in colorectal cancer surgery

BACKGROUND

Surgery is the cornerstone in curative treatment of colorectal cancer. Unfortunately, surgery itself can adversely affect patient health. 'Enhanced Recovery After Surgery' programmes, which include multimodal interventions, have improved patient outcomes substantially. However, these are mainly applied peri- and postoperatively. Multimodal prehabilitation includes multiple preoperative interventions to prepare patients for surgery with the aim of increasing resilience, thereby improving postoperative outcomes.

OBJECTIVES

To determine the effects of multimodal prehabilitation programmes on functional capacity, postoperative complications, and quality of life in adult patients undergoing surgery for colorectal cancer.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase and PsycINFO in January 2021. We also searched trial registries up to March 2021.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) in adult patients with non-metastatic colorectal cancer, scheduled for surgery, comparing multimodal prehabilitation programmes (defined as comprising at least two preoperative interventions) with no prehabilitation. We focused on the following outcomes: functional capacity (i.e. 6-minute walk test, VO2peak, handgrip strength), postoperative outcomes (i.e. complications, mortality, length of hospital stay, emergency department visits, re-admissions), health-related quality of life, compliance, safety of prehabilitation, and return to normal activities.

DATA COLLECTION AND ANALYSIS

Two authors independently selected studies, extracted data, assessed risk of bias and used GRADE to assess the certainty of the evidence. Any disagreements were solved with discussion and consensus. We pooled data to perform meta-analyses, where possible.

MAIN RESULTS

We included three RCTs that enrolled 250 participants with non-metastatic colorectal cancer, scheduled for elective (mainly laparoscopic) surgery. Included trials were conducted in tertiary care centres and recruited patients during periods ranging from 17 months to 45 months. A total of 130 participants enrolled in a preoperative four-week trimodal prehabilitation programme consisting of exercise, nutritional intervention, and anxiety reduction techniques. Outcomes of these participants were compared to those of 120 participants who started an identical but postoperative programme. Postoperatively, prehabilitation may improve functional capacity, determined with the 6-minute walk test at four and eight weeks (mean difference (MD) 26.02, 95% confidence interval (CI) -13.81 to 65.85; 2 studies; n = 131; and MD 26.58, 95% CI -8.88 to 62.04; 2 studies; n = 140); however, the certainty of evidence is low and very low, respectively, due to serious risk of bias, imprecision, and inconsistency. After prehabilitation, the functional capacity before surgery improved, with a clinically relevant mean difference of 24.91 metres (95% CI 11.24 to 38.57; 3 studies; n = 225). The certainty of evidence was moderate due to downgrading for serious risk of bias. Prehabilitation may also result in fewer complications (RR 0.95, 95% CI 0.70 to 1.29; 3 studies; n = 250) and fewer emergency department visits (RR 0.72, 95% CI 0.39 to 1.32; 3 studies; n = 250). The certainty of evidence was low due to downgrading for serious risk of bias and imprecision. On the other hand, prehabilitation may also result in a higher re-admission rate (RR 1.20, 95% CI 0.54 to 2.65; 3 studies; n = 250). The certainty of evidence was again low due to downgrading for risk of bias and imprecision. The effect on VO2peak, handgrip strength, length of hospital stay, mortality rate, health-related quality of life, return to normal activities, safety of the programme, and compliance rate could not be analysed quantitatively due to missing or insufficient data. The included studies did not report a difference between groups for health-related quality of life and length of hospital stay. Data on remaining outcomes were not reported or were reported inadequately in the included studies.

AUTHORS' CONCLUSIONS

Prehabilitation may result in an improved functional capacity, determined with the 6-minute walk test both preoperatively and postoperatively. Complication rates and the number of emergency department visits postoperatively may also diminish due to a prehabilitation programme, while the number of re-admissions may be higher in the prehabilitation group. The certainty of evidence ranges from moderate to very low, due to downgrading for serious risk of bias, imprecision and inconsistency. In addition, only three heterogeneous studies were included in this review. Therefore, the findings of this review should be interpreted with caution. Numerous relevant RCTs are ongoing and will be included in a future update of this review.

Surgery as an Emotional Strain: An Observational Study in Patients Undergoing Elective Colorectal Surgery

Recent research suggests an impact of psychological distress on postoperative outcomes in orthopedic and neurosurgery. It is widely unknown whether patients' mood might affect the postoperative outcome and complication rate in colorectal surgery. Over a period of 22 months, a monocentric, observational study among patients undergoing elective colorectal surgery without the creation of an ostomy was conducted. Patients were asked to fill in a standardized multi-dimensional mood questionnaire (MDMQ) preoperatively as well as on the third, sixth, and ninth postoperative days to assess mood, wakefulness, and arousal. The results of 80 patients (51% male, mean age 59 years) were analyzed. Almost half of the patients (58%) developed postoperative complications according to the Clavien-Dindo classification (Grade I 14%, Grade II 30%, Grade III 9%, Grade IV 3%). Patients' mood increased continually from the preoperative day to the ninth postoperative day. Patients' wakefulness decreased initially (pre- to third postoperative day) and increased again in the further course. Patients' arousal decreased pre- to postoperatively. Neither preoperative mood, nor arousal or wakefulness of patients showed a clear association with the development of postoperative complications. In conclusion, preoperative psychological distress measured by MDMQ did not affect the postoperative complication rate of patients undergoing elective colorectal surgery.

Strategies for optimal perioperative outcomes in gastric cancer

Cancer and surgery represent a major stress on the human body. Any condition that prevents patients from tolerating the physiological stress is a risk factor for poor outcome. There is a need to identify these impairments early in the process with a simple screening, followed by assessments that provide a holistic picture of the patient. The proposed path of multimodal prehabilitation acts synergistically with enhanced recovery after surgery care to achieve optimal patient outcomes.

The Role of Prehabilitation in Modern Esophagogastric Cancer Surgery: A Comprehensive Review

Simple Summary

Surgery is the only potentially curative treatment option for esophagogastric cancer. Although esophagectomy/gastrectomy remains associated with major surgical trauma and significant morbidity. Prehabilitation has emerged as a novel strategy to improve postoperative outcomes by preparing patients for a surgery-associated physiological challenge. We discuss current knowledge and the results of studies on the role of prehabilitation in esophagogastric cancer surgery.

Abstract

Esophagogastric cancer is among the most common malignancies worldwide. Surgery with or without neoadjuvant therapy is the only potentially curative treatment option. Although esophagogastric resections remain associated with major surgical trauma and significant postoperative morbidity. Prehabilitation has emerged as a novel strategy to improve clinical outcomes by optimizing physical and psychological status before major surgery through exercise and nutritional and psychological interventions. Current prehabilitation programs may be unimodal, including only one intervention, or multimodal, combining the benefits of different types of interventions. However, it still is an investigational treatment option mostly limited to clinical trials. In this comprehensive review, we summarize the current evidence for the role of prehabilitation in modern esophagogastric cancer surgery. The available studies are very heterogeneous in design, type of interventions, and measured outcomes. Yet, all of them confirm at least some positive effects of prehabilitation in terms of improved physical performance, nutritional status, quality of life, or even reduced postoperative morbidity. However, the optimal interventions for prehabilitation remain unclear; thus, they cannot be standardized and widely adopted. Future studies on multimodal prehabilitation are necessary to develop optimal programs for patients with esophagogastric cancer.

The Effect of Pre-operative Psychological Interventions on Psychological, Physiological, and Immunological Indices in Oncology Patients: A Scoping Review

Introduction

The stressful pre-operative period exerts a profound impact on psychological, physiological and immunological outcomes. Oncological surgeries, in particular, elicit significantly higher stress responses than most other surgeries. Managing these responses through psychological interventions may improve long-term outcomes. The purpose of the current research was to review studies that have explored pre-operative psychological interventions in cancer patients in order to map the types of current interventions and provide an initial assessment of whether these interventions improved psychological, physiological, and/or immunological indices as well as long-term cancer outcomes.

Methods

A systematic literature search for studies that included pre-operative psychological interventions in oncology patients was conducted, using the databases PubMed and Web of Science. Inclusion criteria included studies pertaining to oncological surgery in adults, study designs that included a clearly defined pre-operative psychological intervention and control group.

Results

We found 44 studies, each using one of the following interventions: psychoeducation, cognitive interventions, relaxation techniques, integrated approaches. All the studies reported improved immediate post-operative psychological, physiological, and/or immunological outcomes. Only a few studies addressed long-term cancer outcomes, and only one reported improved survival.

Conclusions

Research on pre-operative interventions with cancer patients is missing systematic methods. Studies provide varying results, which makes it difficult to compare them and reach reliable conclusions. There is considerable heterogeneity in the literature regarding the specific intervention used, the timing of intervention, the characteristics of the patients studied and the outcome measures. In order to improve research in this field, including the measurement of long-term outcomes, we suggest some steps that should be taken in further research.

Psychological distress among elderly surgical patients who had their surgery postponed during the COVID-19 pandemic

Background

Many institutions withheld elective lists and triaged surgeries during the peak of coronavirus disease 2019 (COVID-19) pandemic. As a result, older surgical patients have had to wait for rescheduled dates in a long waitlist. This study aimed to identify the psychological impact in these patients when they returned for surgery.

Methods

This was a cross-sectional study which included 153 patients aged ≥ 65 years undergoing elective surgery. Trained interviewers recruited and assessed psychological status pre-operatively with two validated questionnaires - Hospital Anxiety and Depression Scale (HADS) and 36-item Short Form Health Survey (SF-36). Specific questions were asked about their postponed surgeries, appetite and fear.

Results

A total of 36 out of 153 (23.5%) patients had their procedures deferred during the first wave of COVID-19 pandemic. Postponed cases were significantly based on the nature of surgery (p = 0.002), cancer diagnosis (p = 0.006) and surgical specialty (p = 0.023). Median HADS scores were higher for patients who were postponed (2.00 versus 4.00 for anxiety, p = 0.180 and 0.00 versus 1.00 for depression, p = 0.424) although no statistical significance was shown. In the whole study population, anxiety was a significant predictor for depression and vice versa (p < 0.001) with other predictive risk factors for anxiety that were age ≥ 85 years old (odds ratio [OR] 6.14, p = 0.018), female (OR 2.41, p = 0.024), cancer (OR 2.19, p = 0.039) and major surgery (OR 2.39, p = 0.023). Similarly, older patients ≥ 85 years old (OR 10.44, p = 0.003) and female (OR 6.07, p = 0.006) had higher risk for depression. Both anxiety and depression were significant risks for loss of appetite (p = 0.005 and 0.001). Lastly, the fear of disease progression due to rescheduling was more frequent in cancer patients (p = 0.035).

Conclusion

The mental health and disease burden of older surgical patients should be taken into careful consideration when cases need to be postponed in our healthcare system.

Finding value with prehabilitation in older persons receiving surgery

PURPOSE OF REVIEW

Patients presenting for surgery are increasingly older and frail. Prehabilitation offers the best hope of preemptive functional optimisation to improve postoperative outcomes. Systematic reviews and meta-analyses show signals of improved function and reduced complications and length of stay, but are hampered by small trials with heterogeneous nature of interventions.

RECENT FINDINGS

The value proposition for prehabilitation is strengthened by applying the following considerations to the evidence. Multimodal prehabilitation programmes incorporating elements of exercise, nutrition, and psychological preparation have a sound physiological basis and will help standardise care delivery and evidence gathering. Targeting prehabilitation resources at high-risk patients may yield higher returns. Effective prehabilitation programmes must be individualised and pragmatic to address known barriers to adherence. The evidence for functional improvement is clear and this aligns with the values of older patients. A comprehensive analysis of value incorporates functional, quality of life, and cost outcomes in addition to conventional morbidity and mortality measures.

SUMMARY

Multimodal prehabilitation delivered by a multidisciplinary team improves functional outcomes following surgery. Function is an integral part of multidimensional value assessment including clinical and experiential measures. Future value enhancements include addressing frailty and overcoming barriers through targeted programme design.

Preoperative Body Image Factors Are Associated with Complications after Breast Reconstruction

BACKGROUND

Psychological factors are broadly understood to contribute to overall health, but their contribution to wound healing is less well defined. Limited data exist on the association of preoperative psychological factors such as body image and postoperative complications. The present study analyzed the association between preoperative body image factors and postoperative complications following breast reconstruction.

METHODS

This was a prospective cohort study of 302 breast cancer patients undergoing breast reconstruction from 2011 to 2015. All patients completed the BREAST-Q; demographics, surgical details, and postoperative complications were recorded. The association of body image factors by means of the BREAST-Q and postoperative complications was analyzed.

RESULTS

On univariate analysis, patients who reported lower preoperative satisfaction with how they appeared in the mirror unclothed, or felt less self-confident or attractive, were significantly more likely to develop an infection postoperatively. Preoperative satisfaction scores were not associated with complications when analyzed in a multivariate fashion. On binomial logistic regression analysis, after controlling for age, body mass index, reconstruction technique, and use of radiotherapy, patients who reported less preoperative satisfaction with how comfortably bras fit or how they appeared in a mirror unclothed were at an increased risk for delayed wound healing.

CONCLUSIONS

Patients with lower preoperative body satisfaction were found to have an increased incidence of infections and delayed wound healing. Although postoperative outcomes are multifactorial, the data suggest that baseline psychological factors such as body image may play a role in postoperative outcomes. Broader use of prehabilitative therapies, targeted at psychosocial factors, may warrant further investigation to optimize postoperative outcomes.

Prehabilitation for Vascular Surgery Patients: Challenges and Opportunities

Global demand for major surgery is rising as a consequence of a growing, ageing population and clinically applicable approaches to perioperative risk reduction have never been needed more. Prehabilitation aims to optimise aerobic capacity and address modifiable risk factors prior to surgery to improve postoperative outcomes. Given the inherently high-risk nature of vascular surgery and the frequently high-acuity, frail, vascular surgical population, the potential to introduce an intervention into the surgical pathway that may reduce postoperative complications cannot be overlooked. The aim of this article is to examine the current evidence base for prehabilitation in patients awaiting vascular surgery, and to summarise the potential benefits, pitfalls, and practicalities of this emerging perioperative intervention. There is a paucity of high-quality research specifically aimed at prehabilitation for patients undergoing vascular surgery, both peripheral and aortic, making it difficult to draw definitive conclusions upon which to base a change in practice. Currently, evidence is taken from small, often single-centre heterogenous studies that vary significantly from each other, meaning that the optimal exercise regimen for patients awaiting vascular surgery has yet to be defined. Establishing the impact of prehabilitation on outcomes for vascular patients is important as the effectiveness of preoperative exercise training is likely to vary between surgical interventions and patient populations. However, extrapolation from other cohorts is possible and indeed forms the basis of many current prehabilitation programmes. Given the success of prehabilitation in other surgical groups, it has potential to become an important future research target for patients awaiting vascular surgery.

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.

Exercise-based dysphagia rehabilitation for adults with oesophageal cancer: a systematic review

BACKGROUND

Dysphagia is prevalent in oesophageal cancer with significant clinical and psychosocial complications. The purpose of this study was i) to examine the impact of exercise-based dysphagia rehabilitation on clinical and quality of life outcomes in this population and ii) to identify key rehabilitation components that may inform future research in this area.

METHODS

Randomised control trials (RCT), non-RCTs, cohort studies and case series were included. 10 databases (CINAHL Complete, MEDLINE, EMBASE, Web of Science, CENTRAL, and ProQuest Dissertations and Theses, OpenGrey, PROSPERO, RIAN and SpeechBITE), 3 clinical trial registries, and relevant conference abstracts were searched in November 2020. Two independent authors assessed articles for eligibility before completing data extraction, quality assessment using ROBINS-I and Downs and Black Checklist, followed by descriptive data analysis. The primary outcomes included oral intake, respiratory status and quality of life. All comparable outcomes were combined and discussed throughout the manuscript as primary and secondary outcomes.

RESULTS

Three single centre non-randomised control studies involving 311 participants were included. A meta-analysis could not be completed due to study heterogeneity. SLT-led post-operative dysphagia intervention led to significantly earlier start to oral intake and reduced length of post-operative hospital stay. No studies found a reduction in aspiration pneumonia rates, and no studies included patient reported or quality of life outcomes. Of the reported secondary outcomes, swallow prehabilitation resulted in significantly improved swallow efficiency following oesophageal surgery compared to the control group, and rehabilitation following surgery resulted in significantly reduced vallecular and pyriform sinus residue. The three studies were found to have 'serious' to 'critical' risk of bias.

CONCLUSIONS

This systematic review highlights a low-volume of low-quality evidence to support exercise-based dysphagia rehabilitation in adults undergoing surgery for oesophageal cancer. As dysphagia is a common symptom impacting quality of life throughout survivorship, findings will guide future research to determine if swallowing rehabilitation should be included in enhanced recovery after surgery (ERAS) programmes. This review is limited by the inclusion of non-randomised control trials and the reliance on Japanese interpretation which may have resulted in bias. The reviewed studies were all of weak design with limited data reported.

Prehabilitation, enhanced recovery after surgery, or both? A narrative review

This narrative review presents a biological rationale and evidence to describe how the preoperative condition of the patient contributes to postoperative morbidity. Any preoperative condition that prevents a patient from tolerating the physiological stress of surgery (e.g. poor cardiopulmonary reserve, sarcopaenia), impairs the stress response (e.g. malnutrition, frailty), and/or augments the catabolic response to stress (e.g. insulin resistance) is a risk factor for poor surgical outcomes. Prehabilitation interventions that include exercise, nutrition, and psychosocial components can be applied before surgery to strengthen physiological reserve and enhance functional capacity, which, in turn, supports recovery through attaining surgical resilience. Prehabilitation complements Enhanced Recovery After Surgery (ERAS) care to achieve optimal patient outcomes because recovery is not a passive process and it begins preoperatively.
