Purpose . Following surgical lung resection , patients frequently suffer functional decline and reduced activity levels . Despite this exercise interventions are not routinely provided . This study aim ed to establish the safety and feasibility of exercise administered following lung resection in an Australian setting . Method . Pilot r and omized controlled trial . Fifteen individuals ( 53 % male ) , mean ± st and ard deviation age 65.5 ± 16.1 years , undergoing surgery for suspected lung cancer . R and omization occurred postoperatively . Control arm received protocol ized inpatient respiratory physiotherapy . Intervention arm additionally received twice daily exercise until discharge home and twice weekly as outpatient for 8 weeks . Outcome measures ( safety , feasibility , functional capacity , functional mobility , and health-related quality of life [ HRQoL ] ) were assessed preoperatively and 2 and 12 weeks postoperatively . Results . Fifteen participants ( lung cancer n = 10 ) were assigned to control ( n = 8) and intervention ( n = 7 ) groups . Inpatient exercise was delivered on 71 % of occasions ( 35 out of 49 planned sessions ) . Four participants attended outpatient exercise sessions and these participants attended sessions on 81 % of occasions ( 52 out of 64 planned sessions ) . No adverse events occurred . There was a significant between group difference in 6-Minute Walk Test ( 6MWT ; P = .024 ) . In both groups the 6MWT declined from baseline to 2 weeks postoperative and then improved up to 12 weeks ; improvements were greater in the intervention group . Intervention was associated with positive trends of improvement in some HRQoL domains . Conclusions . Exercise intervention performed in the inpatient and outpatient setting s for individuals following lung resection  was safe and feasible . The uptake rate for outpatient exercise was 57 % , similar to previous trials ; however , adherence was excellent within the subgroup of participants who attended . Further research is required to investigate the best setting of exercise delivery and explore ways to improve the uptake rate OBJECTIVES Poor aerobic fitness is a potential modifiable risk factor for long-term survival and quality of life in patients with lung cancer . This r and omized trial evaluates the impact of adding rehabilitation ( Rehab ) with high-intensity interval training ( HIIT ) before lung cancer surgery to enhance cardiorespiratory fitness and improve long-term postoperative outcome . METHODS Patients with operable lung cancer were r and omly assigned to  usual care ( UC , n = 77 ) or to intervention group ( Rehab  , n = 74 ) that entailed HIIT that was implemented only preoperatively .  Cardiopulmonary exercise testing ( CPET ) and pulmonary functional tests ( PFTs ) including forced vital capacity ( FVC ) , forced expiratory volume ( FEV 1 ) and carbon monoxide transfer factor ( KCO ) were performed before and 1 year after surgery . RESULTS During the preoperative waiting time ( median 25 days ) , Rehab patients participated to a median of 8 HIIT sessions ( interquartile [ IQ ] 25 - 75 % , 7 - 10 ) . At 1 year follow-up , 91 % UC patients and 93 % Rehab patients were still alive ( P = 0.506 ) . Pulmonary functional changes were non-significant and comparable in both groups ( FEV 1 mean -7.5 % , 95 % CI , -3.6 to -12.9 and in KCO mean 5.8 % 95 % CI 0.8 - 11.8 ) Compared with preoperative CPET results , both groups demonstrated similar reduction in peak oxygen uptake ( mean -12.2 % 95 % CI -4.8 to -18.2 ) and in peak work rate ( mean -11.1 % 95 % CI -4.2 to -17.4 ) . CONCLUSIONS Short-term preoperative rehabilitation with HIIT does not improve pulmonary function and aerobic capacity measured at 1 year after lung cancer resection . TRIAL REGISTRY Clinical Trials.gov ; No. NCT01258478 ; www . clinical trials.gov OBJECTIVES The aim of the study was to develop a multistr and ed pragmatic rehabilitation programme for operable lung cancer patients , that looks into feasibility , process indicators , outcome measures , local adaptability , compliance and potential cost benefit . METHODS An outpatient-based complex intervention , rehabilitation for operated lung cancer ( ROC ) programme , was developed to optimize physical status , prepare for the inpatient journey and support through recovery after surgery . It includes exercise classes , smoking cessation , dietary advice and patient education and was tested in an enriched cohort study within a regional thoracic unit over 18 months . RESULTS A multistr and ed pragmatic rehabilitation programme pre- and post-surgery is feasible . Fifty-eight patients received the intervention and 305 received st and ard care . Both groups were matched for age , lung function comorbidity and type of surgery . Patients in the intervention group attended exercise classes twice a week until surgery , which was not delayed . Patients attended four sessions presurgery ( range 1 - 15 ) , result ing in an improvement of 20 m ( range -73 - 195 , P = 0.001 ) in a 6-min walk test and 0.66 l in forced expiratory volume in 1 s ( range -1.85 from 1.11 , P = 0.009 ) from baseline to presurgery . Fifty-four percentage of smokers in the intervention group stopped smoking . Sixteen percentage of patients were identified as being at risk of malnourishment and received nutritional intervention . There was a trend in patients in the intervention group towards experiencing fewer postoperative pulmonary complications than those in the non-intervention group ( 9 vs 16 % , respectively , P = 0.21 ) and fewer readmissions to hospital because of complications ( 5 vs 14 % respectively , P = 0.12 ) . CONCLUSION Chronic obstructive pulmonary disease-type pulmonary rehabilitation before and after lung cancer surgery is viable , and preliminary results suggest improvement in physical measures . A multicentre , r and omized controlled trial is warranted to confirm clinical efficacy . IS RCT N REGISTRATION NUMBER IS RCT N00061628 Complete surgical resection is the most effective curative treatment for lung cancer . However , many patients with lung cancer also have severe COPD which increases their risk of postoperative complications and their likelihood of being considered " inoperable . " Preoperative pulmonary rehabilitation ( PR ) has been proposed as an intervention to decrease surgical morbidity but there is no established protocol and no r and omized study has been published to date . We tested two preoperative PR interventions in patients undergoing lung cancer resection and with moderate-severe COPD in a r and omized single blinded design . Outcomes were length of hospital stay and postoperative complications . The first study tested 4 weeks of guideline -based PR vs. usual care : that study proved to be very difficult to recruit as patients and providers were reluctant to delay surgery . Nine patients were r and omized and no differences were found between arms . The second study tested ten preoperative PR sessions using a customized protocol with nonst and ard components ( exercise prescription based on self efficacy , inspiratory muscle training , and the practice of slow breathing ) ( n=10 ) vs. usual care ( n=9 ) . The PR arm had shorter length of hospital stay by 3 days ( p=0.058 ) , fewer prolonged chest tubes ( 11 % vs. 63 % , p=0.03 ) and fewer days needing a chest tube ( 8.8 vs. 4.3 days p=0.04 ) compared to the controlled arm . A ten-session preoperative PR intervention may improve post operative lung reexpansion evidence d by shorter chest tube times and decrease the length of hospital stay , a crude estimator of post operative morbidity and costs . Our results suggest the potential for short term preoperative pulmonary rehabilitation interventions in patients with moderate-severe COPD undergoing curative lung resection . 4 weeks of conventional preoperative PR seems non feasible Introduction . Surgical resection in patients with non – small cell lung cancer ( NSCLC ) may be associated with significant morbidity , functional limitations , and decreased quality of life . Objectives . The safety and feasibility of a preoperative and early postoperative rehabilitation program in patients operated for NSCLC was determined in a nonhospital setting , with focus on high-intensity interval exercise . Methods . Forty patients with biopsy-proven NSCLC stages I to IIIa referred for surgical resection at the Department of Cardiothoracic Surgery RT , Rigshospitalet , University of Copenhagen , were r and omly assigned to 1 of 4 groups ( 3 intervention groups and 1 control group ) . The preoperative intervention consisted of a home-based exercise program , while the postoperative exercise program comprised a supervised group exercise program involving resistance and high-intensity interval cardiorespiratory exercise 2 hours weekly for 12 weeks combined with individual counseling . The study endpoints were inclusion rate , adherence , and number of adverse events . Results . Forty patients ( of 124 screened ; 32 % ) were included and r and omized into the 4 groups . The postoperative exercise was completed by 73 % of the patients r and omized to this intervention . No adverse events were observed , indicating that the early postoperative exercise program is safe . The preoperative home-based exercise program was not feasible due to interfering diagnostic procedures and fast-track surgery that left only 1 to 2 weeks between diagnosis and surgery . Conclusion . The early postoperative exercise program for patients with NSCLC was safe and feasible , but in a fast-track set up , a preoperative home-based exercise program was not feasible for this population Objectives : To investigate the effects of a preoperative pulmonary rehabilitation programme in patients with lung cancer undergoing video-assisted thoracic surgery .  Design : R and omized , single-blind controlled trial . Setting : Teaching hospital . Subjects : Patients with suspected or confirmed lung cancer undergoing video-assisted thoracic surgery .  Intervention : Participants were r and omized  to either a prehabilitation group or a control group .  Participants in the prehabilitation group underwent a combination of moderate endurance and resistance training plus breathing exercises three to five times per week . Main measures : The primary outcome of the study was exercise capacity . Secondary outcomes were muscle strength ( Senior Fitness Test ) , health-related quality of life ( Short-Form 36 ) and the postoperative outcomes . Patients were evaluated at baseline ( before r and omization ) , presurgery ( only the prehabilitation group ) , after surgery and three months post-operatively . Results : A total of 40 patients were r and omized and 22 finished the study ( 10 in the prehabilitation group and 12 in the control group ) . Three patients were lost to follow-up at three months . After the training , there was a statistically significant improvement in exercise tolerance ( + 397 seconds , p = 0.0001 ) , the physical summary component of the SF-36 ( + 4.4 points , p = 0.008 ) and muscle strength ( p < 0.01 ) . There were no significant differences between groups after surgery . However , three months postoperatively , significant differences were found in the mean change of exercise capacity ( p = 0.005 ) , physical summary component ( p = 0.001 ) and upper and lower body strength ( p = 0.045 and p = 0.002 ) . Conclusions : A pulmonary rehabilitation programme before video-assisted thoracic surgery seems to improve patients ’ preoperative condition and may prevent functional decline after surgery . Clinical Registration Number : NCT01963923 ( Registration date 10/10/2013 BACKGROUND The impact of short-term preoperative pulmonary rehabilitation on exercise capacity of patients with chronic obstructive pulmonary disease undergoing lobectomy for non-small cell lung cancer is evaluated . METHODS A prospect i ve observational study was design ed . Inclusion criteria consisted of an indication to lung resection because of a clinical stage I or II non-small cell lung cancer and a chronic obstructive disease on preoperative pulmonary function test . In such conditions , maximal oxygen consumption by a cardio-pulmonary exercise test was evaluated ; when this result ed as being < or = 15 ml/kg/min a pulmonary rehabilitation programme lasting 4 weeks was considered . Twelve patients fulfilled inclusion criteria , completed the preoperative rehabilitation programme and underwent a new functional evaluation prior to surgery . The postoperative record of these patients was collected . RESULTS On completion of pulmonary rehabilitation , the resting pulmonary function test and diffuse lung capacity of patients was unchanged , whereas the exercise performance was found to have significantly improved ; the mean increase in maximal oxygen consumption proved to be at 2.8 ml/kg/min ( p<0.01 ) . Eleven patients underwent lobectomy ; no postoperative mortality was noted and mean hospital stay was 17 days . Postoperative pulmonary complication was recorded in 8 patients . CONCLUSIONS Short-term preoperative pulmonary rehabilitation could improve the exercise capacity of patients with chronic obstructive pulmonary disease who are c and i date s for lung resection for non-small cell lung cancer AIMS AND OBJECTIVES To examine the effects of an early postoperative walking exercise programme on postlobectomy lung cancer patients . BACKGROUND Few interventional studies on the postoperative health status of lung cancer patients have considered the efficacy of programmes design ed to improve critical health variables . DESIGN A two-group quasi-experimental , longitudinal approach repeated four times examined participant data collected 12 - 18 hours prior to surgery and again at one , three and six months after surgery . METHODS We assigned the first 33 enrolled participants to the intervention group and the second 33 to the control group . The intervention was a daily supervised walking exercise programme consisting of 12 weeks of brisk walking exercise that began on the day following transfer to the regular ward along with weekly telephone calls until 12 weeks after discharge . Health status was measured using a structured question naire ( World Health Organization Quality of Life , brief version ) and clinical tests ( pulmonary function test and 6-minute walk test ) . We analysed data using general estimating equations , with p < 0·05 considered significant . RESULTS Intervention group pulmonary and physical functions were increasingly better over time than those of the control group , with no significant difference in quality of life between the two groups . Compared to the control group , the intervention group earned significantly better values for FVC% at postoperative month 3 and for FEV1 % at postoperative months 3 and 6 . Intervention group 6MWT scores were significantly better than those of the control group at postoperative months 1 , 3 and 6 . CONCLUSION This study demonstrated the benefits of an early postoperative walking exercise intervention for pulmonary and physical function in postlobectomy lung cancer patients . RELEVANCE TO CLINICAL PRACTICE The results may guide the design of appropriate interventions in the future . Clinical trials in other population s are needed to confirm the results of this study OBJECTIVES The goal of this study was to assess the impact of a preoperative 1-week , systematic , high-intensity inpatient exercise regimen on patients with lung cancer who had risk factors for postoperative pulmonary complications ( PPCs ) . METHODS We conducted a r and omized controlled trial with 101 subjects of a preoperative , 7-day systematic , integrated , high-intensity pulmonary exercise regimen .  The control group received st and ard preoperative care . We analysed the occurrence of PPCs in both groups as the primary outcome ; other outcomes included changes in blood gas , quality of life , peak expiratory flow rate , the 6-min walk distance and others . RESULTS The 6-min walk distance showed an increase of 22.9 ± 25.9 m in the intervention group compared with 4.2 ± 9.2 m in the control group , giving a between-group difference of 18.7 m ( 95 % confidence interval : 8.8 - 28.6 ; P < 0.001 ) ; the peak expiratory flow increased by 25.2 ± 24.6 l/min , compared with 4.2 ± 7.7 l/min ( between-group difference : 21.0 m , 95 % confidence interval : 7.2 - 34.8 ; P = 0.003 ) . The intervention group had a shorter average total ( 15.6 ± 3.6 vs 17.7 ± 5.3 days , P = 0.023 ) and postoperative length of stay ( 6.1 ± 3.0 vs 8.7 ± 4.6 days , P = 0.001 ) than the control group ; the incidence of PPCs ( 9.8 % , 5/51 vs 28.0 % , 14/50 , P = 0.019 ) was significantly lower . A multivariable analysis of the risk of PPCs identified short-term rehabilitation intervention to be an independent risk factor ( odds ratio = 0.156 , 95 % confidence interval : 0.037 - 0.649 , P = 0.011 ) . CONCLUSIONS The study results suggested that a systematic , high-intensity pulmonary exercise programme was a practical strategy when performed preoperatively in patients with lung cancer with risk factors for PPCs . CLINICAL TRIAL REGISTRATION ChiCTR-IOR-16008109 STUDY OBJECTIVES Surgical resection remains the treatment of choice for anatomically resectable non-small cell lung cancer . However , the presence of associated comorbid conditions increases the risk of death and surgical complications . Several studies have evaluated the usefulness of preoperative exercise testing for predicting postoperative morbidity and mortality . The aim of this study was to establish whether exercise testing could predict poor surgical outcome in lung cancer surgery and whether the absolute value or percentage of predicted value is the better predictor of the surgical outcome . DESIGN The study was design ed as a prospect i ve study . PATIENTS AND SETTING One hundred thirty patients with potentially operable lung cancer at Papworth Hospital over 2 years were recruited ; of these , 101 underwent curative surgery .  INTERVENTIONS Spirometry and cardiopulmonary exercise tests were performed for every patient ( n = 99 ) , except for two patients with back problems . We also recorded the outcome of surgery , in particular , complications and mortality . MEASUREMENTS AND RESULTS Mean maximum oxygen transport at peak exercise ( Vo(2)peak ) was 18.3 mL/kg/min ( SD , 4.7 mL/kg/min ) , and mean percentage of predicted Vo(2)peak value was 84.4 % ( SD , 30 % ) . Poor surgical outcome was significantly related to Vo(2)peak percentage of predicted ( p < 0.01 ) but not to the actual oxygen uptake value . CONCLUSIONS The use of the percentage of predicted Vo(2)peak value would be a better indicator of surgical outcome , since it predicts the surgical outcome better , and corrects for normal physiologic ranges . The threshold of Vo(2)peak for surgical intervention could be set between 50 % and 60 % of predicted without excess surgical mortality Introduction : A stepwise approach to the functional assessment of lung resection c and i date s is widely accepted , and this approach incorporates the measurement of exercise peak Vo2 when spirometry and radionuclear studies suggest medical inoperability . A new functional operability ( FO ) algorithm incorporates peak exercise Vo2 earlier in the preoperative assessment to determine which patients require preoperative radionuclear studies . This algorithm has not been studied in a multicenter study . Methods : The CALGB ( Cancer and Leukemia Group B ) performed a prospect i ve multi-institutional study to investigate the use of primary exercise Vo2 measurement for the prediction of surgical risk . Patients with known or suspected resectable non-small cell lung cancer ( NSCLC ) were eligible .  Exercise testing including measurement of peak oxygen uptake ( Vo2 ) , spirometry , and single breath diffusion capacity ( DLCO ) was performed on each patient . Nuclear perfusion scans were obtained on selected high-risk patients . After surgery , morbidity and mortality data were collected and correlated with preoperative data . Mortality and morbidity were retrospectively compared by algorithm-based risk groups . Results : Three hundred forty-six patients with suspected lung cancer from nine institutions underwent thoracotomy with or without resection ; 57 study patients did not undergo thoracotomy .  Patients who underwent surgery had a median survival time of 30.9 months , whereas patients who did not undergo surgery had a median survival time of 15.6 months . Among the 346 patients who underwent thoracotomy , 15 patients died postoperatively ( 4 % ) , and 138 patients ( 39 % ) exhibited at least one cardiorespiratory complication postoperatively . We found that patients who had a peak exercise Vo2 of < 65 % of predicted ( or a peak Vo2/kg < 16 ml/min/kg ) were more likely to suffer complications ( p = 0.0001 ) and were also more likely to have a poor outcome ( respiratory failure or death ) if the peak Vo2 was < 15 ml/min/kg ( p = 0.0356 ) . We also found a subset of 58 patients who did not meet FO algorithm criteria for operability , but who still tolerated lung resection with a 2 % mortality rate . Conclusions : Our data provide multicenter validation for the use of exercise Vo2 for preoperative assessment of lung cancer patients , and we encourage an aggressive approach when evaluating these patients for surgery OBJECTIVE To evaluate the effect of 4 weeks of pulmonary rehabilitation ( PR ) versus chest physical therapy ( CPT ) on the preoperative functional capacity and postoperative respiratory morbidity of patients undergoing lung cancer resection . DESIGN R and omized single-blinded study . SETTING A teaching hospital . PARTICIPANTS Patients undergoing lung cancer resection ( N=24 ) . INTERVENTIONS Patients were r and omly assigned to receive PR ( strength and endurance training ) versus CPT ( breathing exercises for lung expansion ) . Both groups received educational classes . MAIN OUTCOME MEASURES Functional parameters assessed before and after 4 weeks of PR or CPT ( phase 1 ) , and pulmonary complications assessed after lung cancer resection ( phase 2 ) . RESULTS Twelve patients were r and omly assigned to the PR arm and 12 to the CPT arm . Three patients in the CPT arm were not su bmi tted to lung resection because of inoperable cancer . During phase 1 evaluation , most functional parameters in the PR group improved from baseline to 1 month : forced vital capacity ( FVC ) ( 1.47L [ 1.27 - 2.33L ] vs 1.71L [ 1.65 - 2.80L ] , respectively ; P=.02 ) ; percentage of predicted FVC ( FVC% ; 62.5 % [ 49%-71 % ] vs 76 % [ 65%-79.7 % ] , respectively ; P<.05 ) ; 6-minute walk test ( 425.5±85.3 m vs 475±86.5 m , respectively ; P<.05 ) ; maximal inspiratory pressure ( 90±45.9cmH(2)O vs 117.5±36.5cmH(2)O , respectively ; P<.05 ) ; and maximal expiratory pressure ( 79.7±17.1cmH(2)O vs 92.9±21.4cmH(2)O , respectively ; P<.05 ) . During phase 2 evaluation , the PR group had a lower incidence of postoperative respiratory morbidity ( P=.01 ) , a shorter length of postoperative stay ( 12.2±3.6d vs 7.8±4.8d , respectively ; P=.04 ) , and required a chest tube for fewer days ( 7.4±2.6d vs 4.5±2.9d , respectively ; P=.03 ) compared with the CPT arm . CONCLUSIONS These findings suggest that 4 weeks of PR before lung cancer resection improves preoperative functional capacity and decreases the postoperative respiratory morbidity Purpose A previous study investigated the effects of a well-documented COPD exercise protocol in lung cancer patients . The study showed improvements in physical fitness , but poor adherence to continued exercise after intervention . The aim of the present study was to investigate the effect of a modified exercise intervention on post-intervention adherence , and physical fitness in a broad group of lung cancer patients . Methods Fifty-nine patients enrolled in a 9-week exercise program . Eligibility criteria were limited to presence of motivation , and absence of comorbidities that could jeopardize safety . The intervention included three times 3 weeks of exercise ( 3 weeks supervised , 3 weeks home-based and 3 weeks supervised ) . The patient ’s activities were structured by logbooks during the 3 weeks at home . VO2 max was estimated at baseline and at the end of intervention . Self-reported quality of life was recorded before and after the exercise program . Post-intervention exercise activity was assessed by telephone interviews 4 weeks after intervention . Results Fifty-one patients initiated the exercise intervention and 29 patients successfully completed the exercise program .  Full data were available for 25 patients regarding estimated VO2 max . Twenty-six of the 29 were available for follow-up with respect to continuance of physical activity . Among the 26 who completed the 9-week training program , 18 ( 69 % ) continued to be physically active on a daily basis . No change in estimated VO2 max was observed . A trend towards increased quality of life and better symptom control was noted . Conclusions The present study showed an increased level of continuance of physical activity compared to the previous study . The present study could , however , not repeat the significant improvements in estimated VO2 max from the previous study BACKGROUND Post-thoracotomy non-small cell lung cancer ( NSCLC ) patients report cancer-related fatigue ( CRF ) as a severe symptom that may increase the occurrence and severity of other symptoms while decreasing functional status and quality of life ( QOL ) . The aim of this pilot study was to describe the effects of a home-based rehabilitative exercise intervention on CRF , other symptoms , functional status , and QOL for post-surgical NSCLC patients starting within days after hospital discharge . METHODS Seven post-thoracotomy NSCLC patients completed the  Brief Fatigue Inventory ( BFI ) measuring CRF severity , and the  M.D. And erson Symptom Inventory measuring symptom severity at pre- and post-surgery , and at the end of each week of the six-week intervention . Additionally , the Medical Outcomes Short-Form-36 measuring physical and mental functional status ; and the Quality of Life Index ( QLI ) measuring QOL were completed pre- and post-surgery , after week 3 , and at the end of the intervention ( week 6 ) . RESULTS Participants had a mean age of 65 years , a mean of 6 co-morbid conditions , and initiated the intervention within 4 days after hospital discharge . Participants ' CRF severity scores were reduced to mild levels while the mean number of symptoms decreased from 10.4 post-surgery to 7.0 at week 6 with lower levels of severity and interference . Likewise , participants ' post-intervention functional status and QOL improved to near or above pre-surgical levels . CONCLUSIONS The exercise intervention for post-surgical NSCLC patients showed promising preliminary efficacy in improving CRF , other symptom severity , functional status , and QOL . Further testing via a two-arm r and omized controlled trial is being conducted OBJECTIVES Peak VO2 , as measure of physical performance is central to a correct preoperative evaluation in patients with both non-small-cell lung cancer ( NSCLC ) and chronic obstructive pulmonary disease ( COPD ) because it is closely related both to operability criteria and the rate of postoperative complications . Strategies to improve peak VO2 , as a preoperative pulmonary rehabilitation programme ( PRP ) , should be considered favourably in these patients . In order to clarify the role of pulmonary rehabilitation , we have evaluated the effects of 3-week preoperative high-intensity training on physical performance and respiratory function in a group of patients with both NSCLC and COPD who underwent lobectomy . METHODS We studied 40 patients with both NSCLC and COPD , age < 75 years , TNM stages I-II , who underwent lobectomy . Patients were r and omly divided into two groups ( R and S ) : Group R underwent an intensive preoperative PRP , while Group S underwent only lobectomy . We evaluated peak VO2 in all patients at Time 0 ( T0 ) , after PRP/before surgery in Group R/S ( T1 ) and 60 days after surgery , respectively , in both groups ( T2 ) . RESULTS There was no difference between groups in peak VO2 at T0 , while a significant difference was observed both at T1 and T2 . In Group R , peak VO2 improves significantly from T0 to T1 : 14.9 ± 2.3 - 17.8 ± 2.1 ml/kg/min ± st and ard deviation ( SD ) , P < 0.001 ( 64.5 ± 16.5 - 76.1 ± 14.9 % predicted ± SD , P < 0.05 ) and deteriorates from T1 to T2 : 17.8 ± 2.1 - 15.1 ± 2.4 , P < 0.001 ( 76.1 ± 14.9 - 64.6 ± 15.5 , P < 0.05 ) , reverting to a similar value to that at T0 , while in Group S peak VO2 did not change from T0 to T1 and significantly deteriorates from T1 to T2 : 14.5 ± 1.2 - 11.4 ± 1.2 ml/kg/min ± SD , P < 0.00001 ( 60.6 ± 8.4 - 47.4 ± 6.9 % predicted ± SD , P < 0.00001 ) . CONCLUSIONS PRP was a valid preoperative strategy to improve physical performance in patients with  both NSCLC and COPD and this advantage was also maintained after surgery The aim of this study was to explore the effects of presurgical exercise training on quality of life ( QOL ) in patients with malignant lung lesions . Using a single-group prospect i ve design , patients were enrolled in supervised aerobic exercise training for the duration of surgical wait time ( mean 59.7 days ) . Participants completed assessment s of cardiorespiratory fitness ( peak oxygen consumption ) and QOL using the Functional Assessment of Cancer Therapy-Lung scales , including the trial outcome index ( TOI ) and the lung cancer subscale ( LCS ) at baseline , immediately presurgery , and postsurgery ( mean , 57 days ) . 9 participants provided complete data . Repeated- measures analysis indicated a significant effect for time on TOI ( P = .006 ) and LCS ( P = .009 ) . Paired analysis revealed that QOL was unchanged after exercise training ( ie , baseline to presurgery ) , but there were significant and clinical ly meaningful declines from presurgery to postsurgery in the LCS ( −3.6 , P = .021 ) and TOI ( −8.3 , P = .018 ) . Change in peak oxygen consumption from presurgery to postsurgery was significantly associated with change in the LCS ( r = 0.70 , P = .036 ) and TOI ( r = 0.70 , P = .035 ) . Exercise training did not improve QOL from baseline to presurgery . Significant declines in QOL after surgery seem to be related to declines in cardiorespiratory fitness . A r and omized controlled trial is needed to further investigate these relationships OBJECTIVE The purpose of this study was to investigate the impact of pulmonary rehabilitation on surgical morbidity and lung function in lung cancer patients with chronic obstructive pulmonary disease ( COPD ) . METHODS Prospect ively , 22 lung cancer patients with COPD who underwent lobectomy between 2000 and 2003 were enrolled for this study as a rehabilitation group (  Rehab . Group ) . The criteria of COPD were preoperative forced expiratory volume in 1 second (FEV1)/forced vital capacity ( FVC ) < or = 70 % and more than 50 % of low attenuation area in a computed tomography . Preoperatively patients performed aggressive pulmonary exercise for two weeks and received chest physiotherapy postoperatively .  As a historical control , 60 patients with lung cancer who fulfilled the same criteria but did not receive rehabilitation between 1995 and 1999 ( control group ) were entered in this study . RESULTS Patient background s were all equivalent between the two groups . However , FEV1 and FEV1/FVC were significantly lower in the Rehab . Group ( p < 0.05 ) . Prolonged oxygen supplement and tracheostomy tended to be more frequent in the control group . The ratio of actual postoperative to predicted postoperative FEV1 was significantly better in the Rehab . Group ( p = 0.047 ) . Furthermore , postoperative hospital stay was significantly longer in the control group ( p = 0.0003 ) . CONCLUSION Despite lower FEV1 and FEV1/FVC in the Rehab . Group , postoperative pulmonary complications and long hospital stay could be effectively prevented and FEV1 was well preserved by rehabilitation and physiotherapy
In conclusion , preoperative exercise-based training improves pulmonary function before surgery and reduces in-hospital length of stay and postoperative complications after lung resection surgery for lung cancer
Lung cancer is the leading cause of cancer-related death worldwide .
For early stages of the disease , lung resection surgery remains the best treatment with curative intent , but significant morbidity is associated , especially among patients with poor pulmonary function and cardiorespiratory fitness .
In those cases , the implementation of a preoperative exercise-based intervention could optimize patient 's functional status before surgery and improve postoperative outcomes and enhance recovery .
The aim of this systematic review is to provide the current body of knowledge regarding the effectiveness of a preoperative exercise-based intervention on postoperative and functional outcomes in patients with lung cancer su bmi tted to lung resection surgery .
