    Input: 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 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 Background The purpose of the PROLUCA study is to investigate the efficacy of preoperative and early postoperative rehabilitation in a non-hospital setting in patients with operable lung cancer with special focus on exercise . Methods Using a 2x2 factorial design with continuous effect endpoint ( Maximal Oxygen Uptake ( VO2peak ) ) , 380 patients with non-small cell lung cancer ( NSCLC ) stage I-IIIa referred for surgical resection will be r and omly assigned to one of four groups : ( 1 ) preoperative and early postoperative rehabilitation ( starting two weeks after surgery ) ; ( 2 ) preoperative and late postoperative rehabilitation ( starting six weeks after surgery ) ; ( 3 ) early postoperative rehabilitation alone ; ( 4 ) today ’s st and ard care which is postoperative rehabilitation initiated six weeks after surgery . The preoperative rehabilitation program consists of an individually design ed , 30-minute home-based exercise program performed daily . The postoperative rehabilitation program consists of a supervised group exercise program comprising cardiovascular and resistance training two-hour weekly for 12 weeks combined with individual counseling . The primary study endpoint is VO2peak and secondary endpoints include : Six-minute walk distance ( 6MWD ) , one-repetition-maximum ( 1RM ) , pulmonary function , patient-reported outcomes ( PROs ) on health-related quality of life ( HRQoL ) , symptoms and side effects of the cancer disease and the treatment of the disease , anxiety , depression , wellbeing , lifestyle , hospitalization time , sick leave , work status , postoperative complications ( up to 30 days after surgery ) and survival . Endpoints will be assessed at baseline , the day before surgery , pre-intervention , post-intervention , six months after surgery and one year after surgery . Discussion The results of the PROLUCA study may potentially contribute to the identification of the optimal perioperative rehabilitation for operable lung cancer patients focusing on exercise initiated immediately after diagnosis and rehabilitation shortly after surgery . Trial Registration 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 Background Patients with advanced stage non-small cell lung cancer ( NSCLC ) or small cell lung cancer ( SCLC ) often experience multidimensional impairments , affecting quality of life during their course of disease . In lung cancer patients with operable disease , several studies have shown that exercise has a positive impact on quality of life and physical functioning . There is limited evidence regarding efficacy for advanced lung cancer patients undergoing palliative treatment . Therefore , the POSITIVE study aims to evaluate the benefit of a 24-week exercise intervention during palliative treatment in a r and omized controlled setting . Methods / design The POSITIVE study is a r and omized , controlled trial investigating the effects of a 24-week exercise intervention during palliative treatment on quality of life , physical performance and immune function in advanced , non-operable lung cancer patients . 250 patients will be recruited in the Clinic for Thoracic Diseases in Heidelberg , enrolment begun in November 2013 . Main inclusion criterion is histologically confirmed NSCLC ( stage IIIa , IIIb , IV ) or SCLC ( Limited Disease-SCLC , Extensive Disease-SCLC ) not amenable to surgery . Patients are r and omized into two groups . Both groups receive weekly care management phone calls ( CMPCs ) with the goal to assess symptoms and side effects . Additionally , one group receives a combined resistance and endurance training ( 3x/week ) . Primary endpoints are quality of life assessed by the Functional Assessment of Cancer Therapy for patients with lung cancer ( FACT-L , subcategory Physical Well-Being ) and General Fatigue measured by the Multidimensional Fatigue Inventory ( MFI-20 ) . Secondary endpoints are physical performance ( maximal voluntary isometric contraction , 6-min walk distance ) , psychosocial ( depression and anxiety ) and immunological parameters and overall survival . Discussion The aim of the POSITIVE trial is the evaluation of effects of a 24-week structured and guided exercise intervention during palliative treatment stages . Analysis of various outcomes ( such as quality of life , physical performance , self-efficacy , psychosocial and immunological parameters ) will contribute to a better underst and ing of the potential of exercise in advanced lung cancer patients . In contrast to other studies with advanced oncological patients the POSITIVE trial provides weekly phone calls to support patients both in the intervention and control group and to segregate the impact of physical activity on quality of life . Trial registration Clinical Trials.gov NCT02055508 ( Date : December 12 , 2013 BACKGROUND A predicted postoperative forced expiratory volume in 1 second ( FEV1 ) of less than 800 ml or 40 % of predicted is a common criterion for exclusion of patients from lung resection for cancer . Usually , the predicted postoperative lung function is calculated according to a formula based on the number of lung segments that will be resected . Incentive spirometry and specific inspiratory muscle training are two maneuvers that have been used to enhance lung expansion and inspiratory muscle strength in patients with chronic obstructive pulmonary disease and after lung operation . METHODS Thirty-two patients with chronic obstructive pulmonary disease who were c and i date s for lung resection were r and omized into two groups : 17 patients received specific inspiratory muscle training and incentive spirometry , 1 hour per day , six times a week , for 2 weeks before and 3 months after lung resection ( group A ) and 15 patients were assigned to the control group and received no training ( group B ) . RESULTS Inspiratory muscle strength increased significantly in the training group , both before and 3 months after the operation . In group B , the predicted postoperative FEV1 value consistently underestimated the actual postoperative FEV1 by approximately 70 ml in the lobectomy subgroup and by 110 ml in the pneumonectomy subgroup . In group A , the actual postoperative FEV1 was higher than the predicted postoperative FEV1 by 570 ml in the lobectomy subgroup and by 680 ml in the pneumonectomy subgroup of patients . CONCLUSIONS In patients undergoing lung resection the simple calculation of predicted postoperative FEV1 underestimates the actual postoperative FEV1 by a small fraction . Lung functions can be increased significantly when incentive spirometry and specific inspiratory muscle training are used before and after operation Background Many patients with lung cancer are deconditioned with poor physical fitness . Lung resection reduces physical fitness further , impairing the patient 's ability to function in daily life . Methods We conducted a single-blind r and omised controlled trial of high-intensity endurance and strength training ( 60 min , three times a week , 20 weeks ) , starting 5–7 weeks after surgery . The control group received st and ard postoperative care . The primary outcome was the change in peak oxygen uptake measured directly during walking until exhaustion . Other outcomes included changes in pulmonary function , muscular strength by one-repetition maximum ( 1RM ) , total muscle mass measured by dual energy X-ray absorptiometry , daily physical functioning and quality of life ( QoL ) . Results The intention-to-treat analysis of the 61 r and omised patients showed that the exercise group had a greater increase in peak oxygen uptake ( 3.4 mL/kg/min between-group difference , p=0.002 ) , carbon monoxide transfer factor ( Tlco ) ( 5.2 % predicted , p=0.007 ) , 1RM leg press ( 29.5 kg , p<0.001 ) , chair st and ( 2.1 times p<0.001 ) , stair run ( 4.3 steps , p=0.002 ) and total muscle mass ( 1.36 kg , p=0.012 ) compared with the controls . The mean±SD QoL ( SF-36 ) physical component summary score was 51.8±5.5 and 43.3±11.3 ( p=0.006 ) , and the mental component summary score was 55.5±5.3 and 46.6±14.0 ( p=0.015 ) in the exercise and control groups , respectively . Conclusions In patients recently operated for lung cancer , high-intensity endurance and strength training was well tolerated and induced clinical ly significant improvements in peak oxygen uptake , Tlco , muscular strength , total muscle mass , functional fitness and QoL. This study may provide a basis for exercise therapy after lung cancer surgery .
