The effect of a pre- and post-operative exercise program versus standard care on physical activity and sedentary behavior of patients with esophageal and gastric cancer undergoing neoadjuvant treatment prior to surgery (the PERIOP-OG Trial): a randomized controlled trial†. Dis Esophagus 2024:doae044. [PMID: 38769843 DOI: 10.1093/dote/doae044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 04/18/2024] [Accepted: 04/28/2024] [Indexed: 05/22/2024]
Abstract
Neoadjuvant cancer treatment (NCT) reduces both physical fitness and physical activity (PA) levels, which can increase the risk of adverse outcomes in cancer patients. This study aims to determine the effect of exercise prehabilitation on PA and sedentary behavior (SB) in patients undergoing NCT and surgery for esophagogastric malignancies. This study is a randomized pragmatic controlled multi-center trial conducted across three Irish hospitals. Participants were aged ≥18 years scheduled for esophagectomy or gastrectomy and were planned for NCT and surgery. Participants were randomized to an exercise prehabilitation group (EX) that commenced following cancer diagnosis, continued to the point of surgery, and resumed following recovery from surgery for 6 weeks or to usual care (UC) who received routine treatment. The primary outcome measures were PA and SB. Between March 2019 and December 2020, 71 participants were recruited: EX (n = 36) or UC (n = 35). No significant differences were found between the EX group and UC group on levels of PA or SBs across all measured timepoints. Significant decreases in moderate-vigorous physical activity levels (MVPAs) were found between baseline and post-surgery (P = 0.028), pre-surgery and post-surgery (P = 0.001) and pre-surgery and 6-week follow-up (P = 0.022) for all participants. Step count also significantly decreased between pre-surgery and post-surgery (P < 0.001). Baseline aerobic fitness was positively associated to PA levels and negatively associated with SB. Esophagogastric cancer patients have lower than recommended levels of PA at the time of diagnosis and this decreased further following completion of NCT. An optional home- or group-based exercise intervention was not effective in improving PA levels or behaviors across the cancer treatment journey.

A two-arm non-randomised trial of MedEx IMPACT: a community-based, physical activity behaviour change intervention for survivors of cancer. Support Care Cancer 2024; 32:95. [PMID: 38198017 DOI: 10.1007/s00520-023-08263-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 12/16/2023] [Indexed: 01/11/2024]
Abstract
PURPOSE This two-arm non-randomised trial examined the short- and long-term effects of a usual care (UC) community-based exercise programme (MedEx Move On (MMO)), and UC combined with a physical activity (PA) behaviour change (BC) intervention (MedEx IMproved PA after Cancer Treatement (MedEx IMPACT)) on PA levels, cardiorespiratory fitness (CRF) and quality of life (QoL) among survivors of cancer. METHODS Cancer survivors referred to MMO were recruited (n = 191; mean age (± SD) 56 (± 10y), 73% female). Eighty-seven participants were assigned to UC, and 104 participants were assigned to the MedEx IMPACT intervention group (MI). UC and MI both received twice-weekly supervised exercise classes for 12-weeks. MI also received an independent PA programme, 4 PA information sessions and a 1:1 exercise consultation during the 12-week programme. Assessments of physical and psycho-social health, including 6-day accelerometry, the 6-min time trial and the Functional Assessment of Cancer Therapy-General QoL questionnaire, were conducted at baseline (T1), post-intervention (T2) and 3 months following programme completion (T3). RESULTS Linear mixed-model analyses of variance demonstrated significant main effects for time for both groups from T1 to T2 with increases in objectively measured daily steps (p < 0.05), CRF (p < .001) and QoL (p < .01), which were maintained for CRF (p < .001) at T3. MI participants also maintained increases achieved at T2, in steps and QoL, at T3 (p < 0.01). CONCLUSION Twelve weeks of twice-weekly supervised exercise was effective in increasing PA, CRF and QoL among survivors of cancer. MI resulted in the maintenance of all improvements achieved 3 months following programme completion.

The impact of prehabilitation interventions on affective and functional outcomes for young to midlife adult cancer patients: A systematic review. Psychooncology 2022; 31:2050-2062. [PMID: 36073575 PMCID: PMC10092088 DOI: 10.1002/pon.6029] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 08/25/2022] [Accepted: 08/29/2022] [Indexed: 12/14/2022]
Abstract
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.

Study protocol for the investigation of the clinical effectiveness of a physical activity behaviour change intervention for individuals living with and beyond cancer. Contemp Clin Trials Commun 2022; 26:100882. [PMID: 35265769 PMCID: PMC8898780 DOI: 10.1016/j.conctc.2021.100882] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Revised: 11/15/2021] [Accepted: 12/23/2021] [Indexed: 11/30/2022] Open
Abstract
Most individuals living with and beyond cancer are not sufficiently active to achieve the health benefits associated with regular physical activity (PA). The purpose of this study was to describe the study protocol for a two-arm non-randomised comparison trial conducted within a community-based setting, which aimed to investigate the clinical effectiveness of a cancer-specific PA behaviour change (BC) intervention, namely MedEx IMPACT (IMprove Physical Activity after Cancer Treatment), compared to a general exercise rehabilitation programme, among survivors of cancer. Individuals who had completed active-cancer treatment who were referred to a community-based exercise rehabilitation programme were invited to participate in the trial. Participants in the control group (CG) attended twice-weekly supervised exercise classes for 12 weeks. Classes were delivered as part of a chronic illness exercise rehabilitation programme. Participants in the MedEx IMPACT intervention group (IG) also attended the twice-weekly supervised exercise classes for 12 weeks and received cancer-specific materials, namely an independent PA programme, 4 PA information sessions and a 1:1 exercise consultation. The primary outcome was PA levels measured by 6-day accelerometry and self-report PA. Secondary outcomes included cardiorespiratory fitness (CRF), quality of life (QoL) and sedentary behaviour. Outcomes were measured at baseline and months 3, 6 and 12. Few effective PA BC interventions for individuals living with and beyond cancer have been identified. The results of this study will have implications for the planning and provision of community-based exercise oncology rehabilitation programmes for individuals living with and beyond cancer.

Abstract
Abstract
Background
Neoadjuvant cancer treatment (NCT) reduces physical fitness prior to surgery. Lower levels of fitness pre-operatively are associated with increased risk of post-operative morbidity and prolonged recovery. Exercise prehabilitation can optimise fitness for surgery. There is a paucity of evidence regarding the role of community-based exercise programmes during oncological treatment of oesophagogastric malignancies. The aim of the PERIOP-OG trial was to investigate the effect of a community-based exercise prehabilitation programme on physical fitness and other clinical outcomes in patients undergoing NCT and surgical resection for oesophagogastric malignancies.
Methods
Between March 2019 and December 2020, patients with oesophagogastric cancers requiring NCT and surgery were recruited to a multi-centre randomised controlled trial that compared an exercise prehabilitation group to a usual care control group. The exercise programme commenced following cancer diagnosis. All participants undertook assessments at baseline, end of NCT and pre-surgery. The primary endpoint was improvement in cardiorespiratory fitness, measured by the 6-min walk test (6MWT), from baseline and pre-surgery. Secondary endpoints included upper and lower body strength tests (grip strength and 10-sec sit to stand), EQ-5D-5L Health Questionnaire (EQ-5D-5L), Functional Assessment of Cancer Therapy (FACT-E) Questionnaire and Surgical Fear Questionnaire (SFQ).
Results
Seventy-one patients were randomised (exercise n = 36, control n = 35). Baseline characteristics between groups were comparable: mean age (p = 0.87) and sex (p = 0.24). The difference-in-difference (DID) for the exercise prehabilitation showed a significant improvement in 6MWT pre-surgery compared to the usual care group from baseline to pre-surgery: mean (standard deviation) 522 m (17.4) to 582 m (20.1) vs. 498 m (18.2) to 506 m (28.7), p = 0.050. There was no significant DID in grip strength p = 0.770, 10-sec sit to stand (p = 0.100), EQ-5D-5L (p = 0.311), FACT-E (p = 0.105) or SFQ (p = 0.350).
Conclusions
The PERIOP-OG trial demonstrates that a community-based exercise prehabilitation programme initiated at diagnosis, continued during NCT and up to the time of surgery, significantly improves cardiorespiratory fitness. This community exercise prehabilitation model is feasible and sustainable and may provide a standardised framework for the prescription of exercise in oesophagogastric cancer patients.

The effects of neoadjuvant chemoradiotherapy and an in-hospital exercise training programme on physical fitness and quality of life in locally advanced rectal cancer patients: a randomised controlled trial (The EMPOWER Trial). Perioper Med (Lond) 2021; 10:23. [PMID: 34154675 PMCID: PMC8216760 DOI: 10.1186/s13741-021-00190-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2020] [Accepted: 04/22/2021] [Indexed: 01/13/2023] Open
Abstract
BACKGROUND The EMPOWER trial aimed to assess the effects of a 9-week exercise prehabilitation programme on physical fitness compared with a usual care control group. Secondary aims were to investigate the effect of (1) the exercise prehabilitation programme on psychological health; and (2) neoadjuvant chemoradiotherapy (NCRT) on physical fitness and psychological health. METHODS Between October 2013 and December 2016, adults with locally advanced rectal cancer undergoing standardised NCRT and surgery were recruited to a multi-centre trial. Patients underwent cardiopulmonary exercise testing (CPET) and completed HRQoL questionnaires (EORTC-QLQ-C30 and EQ-5D-5L) pre-NCRT and post-NCRT (week 0/baseline). At week 0, patients were randomised to exercise prehabilitation or usual care (no intervention). CPET and HRQoL questionnaires were assessed at week 0, 3, 6 and 9, whilst semi-structured interviews were assessed at week 0 and week 9. Changes in oxygen uptake at anaerobic threshold (VO2 at AT (ml kg-1 min-1)) between groups were compared using linear mixed modelling. RESULTS Thirty-eight patients were recruited, mean age 64 (10.4) years. Of the 38 patients, 33 were randomised: 16 to usual care and 17 to exercise prehabilitation (26 males and 7 females). Exercise prehabilitation significantly improved VO2 at AT at week 9 compared to the usual care. The change from baseline to week 9, when adjusted for baseline, between the randomised groups was + 2.9 ml kg -1 min -1; (95% CI 0.8 to 5.1), p = 0.011. CONCLUSION A 9-week exercise prehabilitation programme significantly improved fitness following NCRT. These findings have informed the WesFit trial (NCT03509428) which is investigating the effects of community-based multimodal prehabilitation before cancer surgery.

Abstract
Background Neoadjuvant cancer treatment is associated with improved survival following major oesophagogastric cancer surgery. The impact of neoadjuvant chemo/chemoradiotherapy on physical fitness and operative outcomes is however unclear. This study aims to investigate the impact of neoadjuvant chemo/chemoradiotherapy on fitness and post-operative mortality. Methods Patients with oesophagogastric cancer scheduled for chemo/chemoradiotherapy and surgery were recruited to a prospective, blinded, multi-centre, observational cohort study. Primary outcomes were changes in fitness with chemo/chemoradiotherapy, measured using cardiopulmonary exercise testing and its association with mortality one-year after surgery. Patients were followed up for re-admission at 30-days, in-hospital morbidity and quality of life (exploratory outcomes). Results In total, 384 patients were screened, 217 met the inclusion criteria, 160 consented and 159 were included (72% male, mean age 65 years). A total of 132 patients (83%) underwent chemo/chemoradiotherapy, 109 (71%) underwent chemo/chemoradiotherapy and two exercise tests, 100 (63%) completed surgery and follow-up. A significant decline in oxygen uptake at anaerobic threshold and oxygen uptake peak was observed following chemo/chemoradiotherapy: -1.25ml.kg -1.min -1 (-1.80 to -0.69) and -3.02ml.kg -1.min -1 (-3.85 to -2.20); p<0.0001). Baseline chemo/chemoradiotherapy anaerobic threshold and peak were associated with one-year mortality (HR=0.72, 95%CI 0.59 to 0.88; p=0.001 and HR=0.85, 0.76 to 0.95; p=0.005). The change in physical fitness was not associated with one-year mortality. Conclusions Chemo/chemoradiotherapy prior to oesophagogastric cancer surgery reduced physical fitness. Lower baseline fitness was associated with reduced overall survival at one-year. Careful consideration of fitness prior to chemo/chemoradiotherapy and surgery is urgently needed.

Perceptions of wellbeing and quality of life following participation in a community-based pre-operative exercise programme in men with newly diagnosed prostate cancer: A qualitative pilot study. PLoS One 2021; 16:e0253018. [PMID: 34111218 PMCID: PMC8191992 DOI: 10.1371/journal.pone.0253018] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Accepted: 05/27/2021] [Indexed: 11/26/2022] Open
Abstract
Background Men with a newly diagnosed prostate cancer are often treated by surgery. The time window between cancer diagnosis and surgery causes high levels of uncertainty and stress, which negatively impact quality of life (QoL). We previously reported a larger intervention pilot study which demonstrated that participation in a community-based pre-operative exercise programme significantly improved physical fitness and health-related quality of life in men with prostate cancer prior to surgery. The aim of the current pilot study was to get an insight into men’s perceptions of wellbeing and QoL following completion of the pre-operative exercise programme. Methods From November 2017 to June 2018, men scheduled for prostate cancer surgery were recruited and took part in a prescribed community-based pre-operative exercise programme in the time available between referral and surgery. Following completion of the pre-operative exercise programme (within 1 week before surgery), participants took part in one semi-structured interview which explored four broad QoL domains: physical, psychological, social, and spiritual wellbeing. Data were analysed using thematic analysis (a bottom up/inductive analysis). Results Eleven men were recruited: mean standard deviation (SD) age was 60 ± 7 years. Data supported four main themes. Participation in the community-based pre-operative exercise training programme (over a mean (SD) of 4 ± 2 weeks) provided participants with: 1) a teachable moment; 2) a journey of preparation; 3) a sense of optimism; and 4) social connectedness prior to surgery. Conclusion This study provides an insight into how the exercise programme impacted wellbeing and QoL in men preparing for prostate cancer surgery. These findings highlight the important role that exercise prehabilitation plays for men preparing for prostate cancer surgery. Such exercise programmes can be easily implemented into standard cancer pathways by establishing relationships between hospital teams and community exercise programmes.

Abstract
Background Treatment for peritoneal malignancy (PM) can include cytoreductive surgery (CRS) and heated intrapertioneal chemotherapy (HIPEC) and is associated with morbidity and mortality. Physical, psychological and nutritional outcomes are important pre-operatively. The aim of this pilot study was to investigate these outcomes in patients with PM before and after CRS-HIPEC. Methods Between June 2018 and November 2019, participants were recruited to a single-centre study. Primary outcome was cardiopulmonary exercise testing (CPET) variables oxygen uptake (VO2) at anaerobic threshold (AT) and at peak. Secondary outcome measures were upper and lower body strength, health related quality of life (HRQoL) and the surgical fear questionnaire. Exploratory outcomes included body mass index, nutrient intake and post-operative outcome. All participants were asked to undertake assessments pre CRS-HIPEC and 12 weeks following the procedure. Results Thirty-nine patients were screened, 38 were eligible and 16 were recruited. Ten female and 6 male, median (IQR) age 53 (42–63) years. Of the 16 patients recruited, 14 proceeded with CRS-HIPEC and 10 competed the follow up assessment at week 12. Pre-operative VO2 at AT and peak was 16.8 (13.7–18) ml.kg-1.min-1 and 22.2 (19.3–25.3) ml.kg-1.min-1, upper body strength was 25.9 (20.3–41.5) kg, lower body strength was 14 (10.4–20.3) sec, HRQoL (overall health status) was 72.5 (46.3–80) % whilst overall surgical fear was 39 (30.5–51). The VO2 at AT decreased significantly (p = 0.05) and HRQoL improved (p = 0.04) between pre and post- CRS-HIPEC. There were no significant differences for any of the other outcome measures. Conclusion This pilot study showed a significant decrease in VO2 at AT and an improvement in overall HRQoL at the 12 week follow up. The findings will inform a larger study design to investigate a prehabilitation and rehabilitation cancer survivorship programme.

Abstract
Background Community-based exercise rehabilitation programmes for chronic disease are an effective alternative to traditional hospital-based programmes. MedEx Wellness is a novel community-based exercise rehabilitation programme that integrates a range of chronic diseases. The aim of this trial was to investigate the effect of participating in MedEx Wellness on physical, clinical and psychological health. Methods A prospective cohort study was conducted. Participants were recruited at induction to the MedEx Wellness programme following referral from healthcare professionals. Participants underwent a baseline assessment before commencing the exercise programme and repeat assessments at 3, 6 and 12 months. The primary outcome was cardiorespiratory fitness (6 minute- time trial) at 12 months. Secondary outcomes included health-related quality of life (EuroQoL-5D, Satisfaction with Life Scale, Warwick Edinburgh Mental Wellbeing Scale, Patient Health Questionnaire8, Functional Assessment of Cancer Therapy Questionnaire), free living activity behavior (accelerometer) and healthcare utilization (recall questionnaire). Tertiary outcomes included blood pressure (24 h), biomarkers (lipids, glucose and C-reactive protein), other components of physical fitness, including strength (handgrip test, sit-to-stand test), flexibility (sit-and-reach test), body composition (body mass index and waist-to-hip ratio), and falls risk (timed up and go test), and claudication time (incremental treadmill walking test), cognitive function, including attention (Attention Network Task), memory (Luck & Vogel Visual Working Memory Task) and cognitive reserve. Exploratory outcomes included psychosocial determinants of physical activity (self-efficacy, social support, intentions). Discussion This trial will evaluate whether participation in the MedEx Wellness programme has positive effects on physical, clinical and psychological health in individuals with a range of chronic diseases.

Trials 2020; 21:638. [PMID: 32660526 PMCID: PMC7359259 DOI: 10.1186/s13063-020-04311-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Accepted: 04/04/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Advances in peri-operative oncological treatment, surgery and peri-operative care have improved survival for patients with oesophagogastric cancers. Neoadjuvant cancer treatment (NCT) reduces physical fitness, which may reduce both compliance and tolerance of NCT as well as compromising post-operative outcomes. This is particularly detrimental in a patient group where malnutrition is common and surgery is demanding. The aim of this trial is to assess the effect on physical fitness and clinical outcomes of a comprehensive exercise training programme in patients undergoing NCT and surgical resection for oesophagogastric malignancies. METHODS The PERIOP-OG trial is a pragmatic, multi-centre, randomised controlled trial comparing a peri-operative exercise programme with standard care in patients with oesophagogastric cancers treated with NCT and surgery. The intervention group undergo a formal exercise training programme and the usual care group receive standard clinical care (no formal exercise advice). The training programme is initiated at cancer diagnosis, continued during NCT, between NCT and surgery, and resumes after surgery. All participants undergo assessments at baseline, post-NCT, pre-surgery and at 4 and 10 weeks after surgery. The primary endpoint is cardiorespiratory fitness measured by demonstration of a 15% difference in the 6-min walk test assessed at the pre-surgery timepoint. Secondary endpoints include measures of physical health (upper and lower body strength tests), body mass index, frailty, activity behaviour, psychological and health-related quality of life outcomes. Exploratory endpoints include a health economics analysis, assessment of clinical health by post-operative morbidity scores, hospital length of stay, nutritional status, immune and inflammatory markers, and response to NCT. Rates of NCT toxicity, tolerance and compliance will also be assessed. DISCUSSION The PERIOP-OG trial will determine whether, when compared to usual care, exercise training initiated at diagnosis and continued during NCT, between NCT and surgery and then during recovery, can maintain or improve cardiorespiratory fitness and other physical, psychological and clinical health outcomes. This trial will inform both the prescription of exercise regimes as well as the design of a larger prehabilitation and rehabilitation trial to investigate whether exercise in combination with nutritional and psychological interventions elicit greater benefits.

Abstract
BACKGROUND The majority of individuals living with and beyond cancer are not sufficiently active to achieve health benefits. OBJECTIVE The aim of this study was to explore individuals' experiences of physical activity (PA) behavior across the cancer journey and to ask individuals living with and beyond cancer to identify strategies to support habitual PA. DESIGN An exploratory, descriptive, qualitative design was used. METHODS Purposive sampling methods were used to recruit individuals living with and beyond cancer who had been referred to, and/or participated in, a community-based exercise program or were attending a cancer support center. The focus group discussions were audio recorded, transcribed verbatim, and analyzed using a thematic analysis approach. RESULTS Seven focus groups were conducted with 41 participants. Many individuals reported that regular PA provided a vehicle for recovery that created a sense of "self-power," defined as taking ownership and control of one's health to increase well-being. Barriers to PA participation included environmental-, patient-, and treatment-related challenges. Recommendations to support long-term adherence to PA included completion of fitness assessments at regular intervals and provision of a home exercise program. LIMITATIONS The benefits and barriers to PA participation for individuals diagnosed with cancers that were not represented may not have been identified. The strategies recommended to support habitual PA may be salient only to individuals whose cancer diagnoses were represented. CONCLUSIONS Exercise is seen as a vehicle for recovery from cancer but long-term adherence for individuals is complex. The findings from this study can inform the development of exercise oncology rehabilitation programs and could support a greater likelihood of program success, thereby optimizing the health, well-being, and quality of life of survivors of cancer.

Compliance, adherence and effectiveness of a community-based pre-operative exercise programme: a pilot study. Perioper Med (Lond) 2019; 8:17. [PMID: 31827773 PMCID: PMC6886214 DOI: 10.1186/s13741-019-0126-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2019] [Accepted: 10/09/2019] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Pre-operative exercise training improves HR components of fitness and HRQoL following hospital-based programmes. OBJECTIVE To assess compliance and adherence of a pragmatic community-based preoperative exercise programme and its effect on health-related (HR) components of fitness and health-related quality of life (HRQoL). METHODS Thirty-two surgical oncological participants (15 prostate cancer and 17 colorectal cancer (CRC)) were recruited and assessed to measure HR components of fitness (strength and functional exercise capacity) and HRQoL. An exercise programme was prescribed in the time available prior to surgery with repeat assessments pre-operatively. RESULTS Twenty-four participants (14 prostate cancer and 10 CRC) completed the full study (75% compliance). Exercise training was delivered over a median interquartile range (IQR) of 4 (3-4) weeks and 2 (1-3) weeks for the prostate cancer and CRC participants, with > 80% adherence. From baseline to post-exercise intervention, there were significant improvements in lower body strength in the prostate cancer group (p = 0.045), the CRC group (p = 0.001), and in both groups overall (p = .001). Additionally, there were statistically significant improvements in HRQoL: global health status for CRC group (p = 0.025) and for both groups overall (p = 0.023); emotional health subscale for the prostate cancer group (p = 0.048) and for both groups overall (p = 0.027); nausea/vomiting/pain subscale for the CRC group (p = 0.005) and for both groups overall (p = 0.030); and for health scale status for the prostate cancer group (p = 0.019) and for both groups overall (p = 0.006). CONCLUSION This community-based pre-operative exercise programme showed acceptable compliance and adherence rates, and significantly increased upper and lower body strength and HRQoL. Pre-operative exercise training should be considered as early as possible in the surgical-oncology pathway and respected within patient scheduling.

Perioperative prehabilitation and rehabilitation in esophagogastric malignancies: a systematic review. Dis Esophagus 2019; 32:5519688. [PMID: 31206582 DOI: 10.1093/dote/doz058] [Citation(s) in RCA: 39] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2018] [Revised: 04/30/2019] [Accepted: 05/15/2019] [Indexed: 12/11/2022]
Abstract
Cancers of the esophagus and stomach are challenging to treat. With the advent of neoadjuvant therapies, patients frequently have a preoperative window with potential to optimize their status before major resectional surgery. It is unclear as to whether a prehabilitation or optimization program can affect surgical outcomes. This systematic review appraises the current evidence for prehabilitation and rehabilitation in esophagogastric malignancy. A literature search was performed according to PRISMA guidelines using PubMed, EMBASE, Cochrane Library, Google Scholar, and Scopus. Studies including patients undergoing esophagectomy or gastrectomy were included. Studies reporting on at least one of aerobic capacity, muscle strength, quality of life, morbidity, and mortality were included. Twelve studies were identified for inclusion, comprising a total of 937 patients. There was significant heterogeneity between studies, with a variety of interventions, timelines, and outcome measures reported. Inspiratory muscle training (IMT) consistently showed improvements in functional status preoperatively, with three studies showing improvements in respiratory complications with IMT. Postoperative rehabilitation was associated with improved clinical outcomes. There may be a role for prehabilitation among patients undergoing major resectional surgery in esophagogastric malignancy. A large randomized controlled trial is warranted to investigate this further.

Total haemoglobin mass, but not haemoglobin concentration, is associated with preoperative cardiopulmonary exercise testing-derived oxygen-consumption variables. Br J Anaesth 2018; 118:747-754.

Abstract
Background Cardiopulmonary exercise testing (CPET) measures peak exertional oxygen consumption ( V˙O2peak ) and that at the anaerobic threshold ( V˙O2 at AT, i.e. the point at which anaerobic metabolism contributes substantially to overall metabolism). Lower values are associated with excess postoperative morbidity and mortality. A reduced haemoglobin concentration ([Hb]) results from a reduction in total haemoglobin mass (tHb-mass) or an increase in plasma volume. Thus, tHb-mass might be a more useful measure of oxygen-carrying capacity and might correlate better with CPET-derived fitness measures in preoperative patients than does circulating [Hb]. Methods Before major elective surgery, CPET was performed, and both tHb-mass (optimized carbon monoxide rebreathing method) and circulating [Hb] were determined. Results In 42 patients (83% male), [Hb] was unrelated to V˙O2 at AT and V˙O2peak ( r =0.02, P =0.89 and r =0.04, P =0.80, respectively) and explained none of the variance in either measure. In contrast, tHb-mass was related to both ( r =0.661, P <0.0001 and r =0.483, P =0.001 for V˙O2 at AT and V˙O2peak , respectively). The tHb-mass explained 44% of variance in V˙O2 at AT ( P <0.0001) and 23% in V˙O2peak ( P =0.001). Conclusions In contrast to [Hb], tHb-mass is an important determinant of physical fitness before major elective surgery. Further studies should determine whether low tHb-mass is predictive of poor outcome and whether targeted increases in tHb-mass might thus improve outcome.

Physical activity levels in locally advanced rectal cancer patients following neoadjuvant chemoradiotherapy and an exercise training programme before surgery: a pilot study. Perioper Med (Lond) 2017; 6:3. [PMID: 28228938 PMCID: PMC5311720 DOI: 10.1186/s13741-017-0058-3] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2016] [Accepted: 01/04/2017] [Indexed: 01/13/2023] Open
Abstract
Background The aim of this pilot study was to measure changes in physical activity level (PAL) variables, as well as sleep duration and efficiency in people with locally advanced rectal cancer (1) before and after neoadjuvant chemoradiotherapy (CRT) and (2) after participating in a pre-operative 6-week in-hospital exercise training programme, following neoadjuvant CRT prior to major surgery, compared to a usual care control group. Methods We prospectively studied 39 consecutive participants (27 males). All participants completed standardised neoadjuvant CRT: 23 undertook a 6-week in-hospital exercise training programme following neoadjuvant CRT. These were compared to 16 contemporaneous non-randomised participants (usual care control group). All participants underwent a continuous 72-h period of PA monitoring by SenseWear biaxial accelerometer at baseline, immediately following neoadjuvant CRT (week 0), and at week 6 (following the exercise training programme). Results Of 39 recruited participants, 23 out of 23 (exercise) and 10 out of 16 (usual care control) completed the study. In all participants (n = 33), there was a significant reduction from baseline (pre-CRT) to week 0 (post-CRT) in daily step count: median (IQR) 4966 (4435) vs. 3044 (3265); p < 0.0001, active energy expenditure (EE) (kcal): 264 (471) vs. 154 (164); p = 0.003, and metabolic equivalent (MET) (1.3 (0.6) vs. 1.2 (0.3); p = 0.010). There was a significant improvement in sleep efficiency (%) between week 0 and week 6 in the exercise group compared to the usual care control group (80 (13) vs. 78 (15) compared to (69 ((24) vs. 76 (20); p = 0.022), as well as in sleep duration and lying down time (p < 0.05) while those in active EE (kcal) (152 (154) vs. 434 (658) compared to (244 (198) vs. 392 (701) or in MET (1.3 (0.4) vs. 1.5 (0.5) compared to (1.1 (0.2) vs. 1.5 (0.5) were also of importance but did not reach statistical significance (p > 0.05). An apparent improvement in daily step count and overall PAL in the exercise group was not statistically significant. Conclusions PAL variables, daily step count, EE and MET significantly reduced following neoadjuvant CRT in all participants. A 6-week pre-operative in-hospital exercise training programme improved sleep efficiency, sleep duration and lying down time when compared to participants receiving usual care.

The effect of neoadjuvant chemotherapy and chemoradiotherapy on exercise capacity and outcome following upper gastrointestinal cancer surgery: an observational cohort study. BMC Cancer 2016; 16:710.

Abstract
Background In 2014 approximately 21,200 patients were diagnosed with oesophageal and gastric cancer in England and Wales, of whom 37 % underwent planned curative treatments. Potentially curative surgical resection is associated with significant morbidity and mortality. For operable locally advanced disease, neoadjuvant chemotherapy (NAC) improves survival over surgery alone. However, NAC carries the risk of toxicity and is associated with a decrease in physical fitness, which may in turn influence subsequent clinical outcome. Lower levels of physical fitness are associated with worse outcome following major surgery in general and Upper Gastrointestinal Surgery (UGI) surgery in particular. Cardiopulmonary exercise testing (CPET) provides an objective assessment of physical fitness. The aim of this study is to test the hypothesis that NAC prior to upper gastrointestinal cancer surgery is associated with a decrease in physical fitness and that the magnitude of the change in physical fitness will predict mortality 1 year following surgery. Methods This study is a multi-centre, prospective, blinded, observational cohort study of participants with oesophageal and gastric cancer scheduled for neoadjuvant cancer treatment (chemo- and chemoradiotherapy) and surgery. The primary endpoints are physical fitness (oxygen uptake at lactate threshold measured using CPET) and 1-year mortality following surgery; secondary endpoints include post-operative morbidity (Post-Operative Morbidity Survey (POMS)) 5 days after surgery and patient related quality of life (EQ-5D-5 L). Discussion The principal benefits of this study, if the underlying hypothesis is correct, will be to facilitate better selection of treatments (e.g. NAC, Surgery) in patients with oesophageal or gastric cancer. It may also be possible to develop new treatments to reduce the effects of neoadjuvant cancer treatment on physical fitness. These results will contribute to the design of a large, multi-centre trial to determine whether an in-hospital exercise-training programme that increases physical fitness leads to improved overall survival.

Timing of surgery following neoadjuvant chemoradiotherapy in locally advanced rectal cancer - A comparison of magnetic resonance imaging at two time points and histopathological responses. Eur J Surg Oncol 2016; 42:1350-8. [PMID: 27160356 DOI: 10.1016/j.ejso.2016.04.003] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2015] [Revised: 03/17/2016] [Accepted: 04/07/2016] [Indexed: 01/01/2023] Open
Abstract
PURPOSE There is wide inter-institutional variation in the interval between neoadjuvant chemoradiotherapy (NACRT) and surgery for locally advanced rectal cancer. We aimed to assess the association of magnetic resonance imaging (MRI) at 9 and 14 weeks post-NACRT; T-staging (ymrT) and post-NACRT tumour regression grading (ymrTRG) with histopathological outcomes; histopathological T-stage (ypT) and histopathological tumour regression grading (ypTRG) in order to inform decision-making about timing of surgery. PATIENTS AND METHODS We prospectively studied 35 consecutive patients (26 males) with MRI-defined resection margin threatened rectal cancer who had completed standardized NACRT. Patients underwent a MRI at Weeks 9 and 14 post-NACRT, and surgery at Week 15. Two readers independently assessed MRIs for ymrT, ymrTRG and volume change. ymrT and ymrTRG were analysed against histopathological ypT and ypTRG as predictors by logistic regression modelling and receiver operating characteristic (ROC) curve analyses. RESULTS Thirty-five patients were recruited. Inter-observer agreement was good for all MR variables (Kappa > 0.61). Considering ypT as an outcome variable, a stronger association of favourable ymrTRG and volume change at Week 14 compared to Week 9 was found (ymrTRG - p = 0.064 vs. p = 0.010; Volume change - p = 0.062 vs. p = 0.007). Similarly, considering ypTRG as an outcome variable, a greater association of favourable ymrTRG and volume change at Week 14 compared to Week 9 was found (ymrTRG - p = 0.005 vs. p = 0.042; Volume change - p = 0.004 vs. 0.055). CONCLUSION Following NACRT, greater tumour down-staging and volume reduction was observed at Week 14. Timing of surgery, in relation to NACRT, merits further investigation.

The effects of neoadjuvant chemoradiotherapy and an in-hospital exercise training programme on physical fitness and quality of life in locally advanced rectal cancer patients (The EMPOWER Trial): study protocol for a randomised controlled trial. Trials 2016; 17:24. [PMID: 26762365 PMCID: PMC4710998 DOI: 10.1186/s13063-015-1149-4] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2015] [Accepted: 12/29/2015] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND The standard treatment pathway for locally advanced rectal cancer is neoadjuvant chemoradiotherapy (CRT) followed by surgery. Neoadjuvant CRT has been shown to decrease physical fitness, and this decrease is associated with increased post-operative morbidity. Exercise training can stimulate skeletal muscle adaptations such as increased mitochondrial content and improved oxygen uptake capacity, both of which are contributors to physical fitness. The aims of the EMPOWER trial are to assess the effects of neoadjuvant CRT and an in-hospital exercise training programme on physical fitness, health-related quality of life (HRQoL), and physical activity levels, as well as post-operative morbidity and cancer staging. METHODS/DESIGN The EMPOWER Trial is a randomised controlled trial with a planned recruitment of 46 patients with locally advanced rectal cancer and who are undergoing neoadjuvant CRT and surgery. Following completion of the neoadjuvant CRT (week 0) prior to surgery, patients are randomised to an in-hospital exercise training programme (aerobic interval training for 6 to 9 weeks) or a usual care control group (usual care and no formal exercise training). The primary endpoint is oxygen uptake at lactate threshold ([Formula: see text] at [Formula: see text]) measured using cardiopulmonary exercise testing assessed over several time points throughout the study. Secondary endpoints include HRQoL, assessed using semi-structured interviews and questionnaires, and physical activity levels assessed using activity monitors. Exploratory endpoints include post-operative morbidity, assessed using the Post-Operative Morbidity Survey (POMS), and cancer staging, assessed by using magnetic resonance tumour regression grading. DISCUSSION The EMPOWER trial is the first randomised controlled trial comparing an in-hospital exercise training group with a usual care control group in patients with locally advanced rectal cancer. This trial will allow us to determine whether exercise training following neoadjuvant CRT can improve physical fitness and activity levels, as well as other important clinical outcome measures such as HRQoL and post-operative morbidity. These results will aid the design of a large, multi-centre trial to determine whether an increase in physical fitness improves clinically relevant post-operative outcomes.

Exercise intervention in people with cancer undergoing neoadjuvant cancer treatment and surgery: A systematic review. Eur J Surg Oncol 2015; 42:28-38.

Abstract
BACKGROUND Neoadjuvant cancer treatment decreases physical fitness. Low levels of physical fitness are associated with poor surgical outcome. Exercise training can stimulate skeletal muscle adaptations, such as increased mitochondrial content and improved oxygen uptake capacity that may contribute to improving physical fitness. This systematic review evaluates the evidence in support of exercise training in people with cancer undergoing the "dual hit" of neoadjuvant cancer treatment and surgery. METHODS We conducted a systematic database search of Embase Ovid, Ovid Medline without Revisions, SPORTDiscus, Web of Science, Cochrane Central Register of Controlled Trials Library and ClinicalTrials.gov to identify trials addressing the effect of exercise training in people scheduled for neoadjuvant cancer treatment and surgery. Data extraction and analysis were based on a pre-defined plan. RESULTS The database search yielded 6489 candidate abstracts. Ninety-four references included the required terms. Four studies were eligible for inclusion (breast cancer, locally advanced rectal cancer). All studies reported that exercise training was safe and feasible and that adherence rates were acceptable (66-96%). In-hospital exercise training improves physical fitness however the impact on HRQoL and other clinical important outcomes was uncertain. CONCLUSION This is the first systematic review of the effects of exercise training in people scheduled for "dual-hit" treatment. This evidence synthesis indicates that this approach is safe and feasible but that there are insufficient controlled trials in this area to draw reliable conclusions about the efficacy of such an intervention, the optimal characteristics of the intervention, or the impact on clinical or patient reported outcomes.

Abstract
BACKGROUND Remaining physically active during and after cancer treatment is known to improve associated adverse effects, improve overall survival and reduce the probability of relapse. This systematic review addresses the question: is an exercise training programme beneficial in people with cancer undergoing adjuvant cancer treatment following surgery. METHODS A systematic database search of Embase, Ovid, Medline without Revisions, SPORTDiscus, Web of Science, Cochrane Library and ClinicalTrials.gov for any randomised controlled trials (RCT) or non-RCT addressing the effect of an exercise training programme in those having adjuvant cancer treatment following surgery was conducted. RESULTS The database search yielded 6489 candidate abstracts of which 94 references included the required terms. A total of 17 articles were included in this review. Exercise training is safe and feasible in the adjuvant setting and furthermore may improve measures of physical fitness and health related quality of life (HRQoL). CONCLUSION This is the first systematic review on exercise training interventions in people with cancer undergoing adjuvant cancer treatment following surgery. Due to the lack of adequately powered RCTs in this area, it remains unclear whether exercise training in this context improves clinical outcomes other physical fitness and HRQoL. It remains unclear what is the optimal timing of initiation of an exercise programme and what are the best combinations of elements within an exercise training programme to optimise training efficacy. Furthermore, it is unclear if initiating such exercise programmes at cancer diagnosis may have a long-lasting effect on physically activity throughout the subsequent life course.

The Effect of beta-blockade on objectively measured physical fitness in patients with abdominal aortic aneurysms--A blinded interventional study. Br J Anaesth 2015; 114:878-85.

Abstract
BACKGROUND Perioperative beta-blockade is widely used, especially before vascular surgery; however, its impact on exercise performance assessed using cardiopulmonary exercise testing (CPET) in this group is unknown. We hypothesized that beta-blocker therapy would significantly improve CPET-derived physical fitness in this group. METHODS We recruited patients with abdominal aortic aneurysms (AAA) of <5.5 cm under surveillance. All patients underwent CPET on and off beta-blockers. Patients routinely prescribed beta-blockers underwent a first CPET on medication. Beta-blockers were stopped for one week before a second CPET. Patients not routinely taking beta-blockers underwent the first CPET off treatment, then performed a second CPET after commencement of bisoprolol for at least 48 h. Oxygen uptake (.VO2) at estimated lactate threshold and .VO2 at peak were primary outcome variables. A linear mixed-effects model was fitted to investigate any difference in adjusted CPET variables on and off beta-blockers. RESULTS Forty-eight patients completed the study. No difference was observed in .VO2 at estimated lactate threshold and .VO2 at peak; however, a significant decrease in .VE/.VCO2 at estimated lactate threshold and peak, an increase in workload at estimated lactate threshold., O2 pulse and heart rate both at estimated lactate threshold and peak was found with beta-blockers. Patients taking beta-blockers routinely (chronic group) had worse exercise performance (lower .VO2 ). CONCLUSIONS Beta blockade has a significant impact on CPET-derived exercise performance, albeit without changing .VO2 at estimated lactate threshold and.VO2 at peak. This supports performance of preoperative CPET on or off beta-blockers depending on local perioperative practice. CLINICAL TRIAL REGISTRATION NCT 02106286.

Abstract
Background In the United Kingdom, patients with locally advanced rectal cancer routinely receive neoadjuvant chemoradiotherapy. However, the effects of this on physical fitness are unclear. This pilot study is aimed to investigate the effect of neoadjuvant chemoradiotherapy on objectively measured in vivo muscle mitochondrial function and whole-body physical fitness. Methods We prospectively studied 12 patients with rectal cancer who completed standardized neoadjuvant chemoradiotherapy, recruited from a large tertiary cancer centre, between October 2012 and July 2013. All patients underwent a cardiopulmonary exercise test and a phosphorus magnetic resonance spectroscopy quadriceps muscle exercise-recovery study before and after neoadjuvant chemoradiotherapy. Data were analysed and reported blind to patient identity and clinical course. Primary variables of interest were the two physical fitness measures; oxygen uptake at estimated anaerobic threshold and oxygen uptake at Peak exercise (ml.kg−1.min−1), and the post-exercise phosphocreatine recovery rate constant (min−1), a measure of muscle mitochondrial capacity in vivo. Results Median age was 67 years (IQR 64–75). Differences (95%CI) in all three primary variables were significantly negative post-NACRT: Oxygen uptake at estimated anaerobic threshold −2.4 ml.kg−1.min−1 (−3.8, −0.9), p = 0.004; Oxygen uptake at Peak −4.0 ml.kg−1.min−1 (−6.8, −1.1), p = 0.011; and post-exercise phosphocreatine recovery rate constant −0.34 min−1 (−0.51, −0.17), p<0.001. Conclusion The significant decrease in both whole-body physical fitness and in vivo muscle mitochondrial function raises the possibility that muscle mitochondrial mechanisms, no doubt multifactorial, may be important in deterioration of physical fitness following neoadjuvant chemoradiotherapy. This may have implications for targeted interventions to improve physical fitness pre-surgery. Trial Registration Clinicaltrials.gov registration NCT01859442

Abstract
BACKGROUND Patients requiring surgery for locally advanced rectal cancer often additionally undergo neoadjuvant chemoradiotherapy (NACRT), of which the effects on physical fitness are unknown. The aim of this feasibility and pilot study was to investigate the effects of NACRT and a 6 week structured responsive exercise training programme (SRETP) on oxygen uptake [Formula: see text] at lactate threshold ([Formula: see text]) in such patients. METHODS We prospectively studied 39 consecutive subjects (27 males) with T3-4/N+ resection margin threatened rectal cancer who completed standardized NACRT. Subjects underwent cardiopulmonary exercise testing at baseline (pre-NACRT), at week 0 (post-NACRT), and week 6 (post-SRETP). Twenty-two subjects undertook a 6 week SRETP on a training bike (three sessions per week) between week 0 and week 6 (exercise group). These were compared with 17 contemporaneous non-randomized subjects (control group). Changes in [Formula: see text] at [Formula: see text] over time and between the groups were compared using a compound symmetry covariance linear mixed model. RESULTS Of 39 recruited subjects, 22 out of 22 (exercise) and 13 out of 17 (control) completed the study. There were differences between the exercise and control groups at baseline [age, ASA score physical status, World Health Organisation performance status, and Colorectal Physiologic and Operative Severity Score for the Enumeration of Mortality and Morbidity (CR-POSSUM) predicted mortality]. In all subjects, [Formula: see text] at [Formula: see text] significantly reduced between baseline and week 0 [-1.9 ml kg(-1) min(-1); 95% confidence interval (CI) -1.3, -2.6; P<0.0001]. In the exercise group, [Formula: see text] at [Formula: see text] significantly improved between week 0 and week 6 (+2.1 ml kg(-1) min(-1); 95% CI +1.3, +2.9; P<0.0001), whereas the control group values were unchanged (-0.7 ml kg(-1) min(-1); 95% CI -1.66, +0.37; P=0.204). CONCLUSIONS NACRT before rectal cancer surgery reduces physical fitness. A structured exercise intervention is feasible post-NACRT and returns fitness to baseline levels within 6 weeks.

Abstract
BACKGROUND Patients requiring surgery for locally advanced rectal cancer often additionally undergo neoadjuvant chemoradiotherapy (NACRT), of which the effects on physical fitness are unknown. The aim of this feasibility and pilot study was to investigate the effects of NACRT and a 6 week structured responsive exercise training programme (SRETP) on oxygen uptake [Formula: see text] at lactate threshold ([Formula: see text]) in such patients. METHODS We prospectively studied 39 consecutive subjects (27 males) with T3-4/N+ resection margin threatened rectal cancer who completed standardized NACRT. Subjects underwent cardiopulmonary exercise testing at baseline (pre-NACRT), at week 0 (post-NACRT), and week 6 (post-SRETP). Twenty-two subjects undertook a 6 week SRETP on a training bike (three sessions per week) between week 0 and week 6 (exercise group). These were compared with 17 contemporaneous non-randomized subjects (control group). Changes in [Formula: see text] at [Formula: see text] over time and between the groups were compared using a compound symmetry covariance linear mixed model. RESULTS Of 39 recruited subjects, 22 out of 22 (exercise) and 13 out of 17 (control) completed the study. There were differences between the exercise and control groups at baseline [age, ASA score physical status, World Health Organisation performance status, and Colorectal Physiologic and Operative Severity Score for the Enumeration of Mortality and Morbidity (CR-POSSUM) predicted mortality]. In all subjects, [Formula: see text] at [Formula: see text] significantly reduced between baseline and week 0 [-1.9 ml kg(-1) min(-1); 95% confidence interval (CI) -1.3, -2.6; P<0.0001].

The effects of neoadjuvant chemoradiotherapy on physical fitness and morbidity in rectal cancer surgery patients. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2014; 40:1421-8. [PMID: 24784775 DOI: 10.1016/j.ejso.2014.03.021] [Citation(s) in RCA: 77] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2014] [Revised: 03/15/2014] [Accepted: 03/22/2014] [Indexed: 11/26/2022]
Abstract
BACKGROUND Neoadjuvant chemoradiotherapy (NACRT) followed by surgery for resectable locally advanced rectal cancer improves outcome compared with surgery alone. Our primary hypothesis was that NACRT impairs objectively-measured physical fitness. We also wished to explore the relationship between fitness and postoperative outcome. METHOD In an observational study, we prospectively studied 27 consecutive patients, of whom 25 undertook cardiopulmonary exercise testing (CPET) 2 weeks before and 7 weeks after standardized NACRT, then underwent surgery. In-hospital post-operative morbidity and mortality were recorded. Patients were followed up to 1 year for mortality. Data was analysed blind to clinical details. Receiver-operating characteristic (ROC) analysis defined the predictive value of CPET for in-hospital morbidity at day 5. RESULTS Oxygen uptake ( [Formula: see text] in ml kg(-1) min(-1)) at estimated lactate threshold (θˆL) and at peak exercise ( [Formula: see text] at peak in ml kg(-1) min(-1)) both significantly decreased post-NACRT: [Formula: see text] at θˆL 12.1 (pre-NACRT) vs. 10.6 (post-NACRT), p < 0.001 (95%CI -1.7, -1.2); [Formula: see text] at peak 18.1 vs. 16.7, p < 0.001 (95%CI -3.1, -1.0). Optimal [Formula: see text] at θˆL and peak pre-NACRT for predicting postoperative morbidity were 12.0 and 18.1 ( [Formula: see text] at θˆL - AUC = 0.71, 77% sensitive and 75% specific; [Formula: see text] at peak - AUC = 0.75, 78% sensitive and 76% specific). Optimal [Formula: see text] at θˆL and peak post-NACRT for predicting postoperative morbidity were 10.7 and 16.7 ( [Formula: see text] at θˆL - AUC = 0.72, 77% sensitive and 83% specific; [Formula: see text] at peak - AUC = 0.80, 85% sensitive and 83% specific). CONCLUSION NACRT before major rectal cancer surgery significantly decreased physical fitness as assessed by CPET. TRIALS REGISTRY NUMBER NCT01334593.
