    Input: OBJECTIVES Physical activity has been infrequently measured objective ly in non-small cell lung cancer ( NSCLC ) . We aim ed to investigate levels of physical activity , functional and patient reported outcomes at diagnosis and over six months in participants with recently diagnosed NSCLC and compare results with both physical activity guidelines and outcomes of similar-aged healthy individuals . METHODS This prospect i ve observational study assessed 50 individuals from three Australian tertiary hospitals with stage I-IIIB NSCLC at diagnosis , then 10 weeks and six months later . Thirty five healthy individuals without cancer were assessed once . Outcome measures included  tri-axial accelerometery ( number of steps per day ) , six minute walk distance ( 6MWD ) , muscle strength and question naires including health-related quality of life ( HRQoL ) . RESULTS Individuals with NSCLC were engaged in significantly less physical activity than similar-aged healthy individuals , with 60 % not meeting physical activity guidelines . At diagnosis they had worse quadriceps strength , nutritional status and HRQoL. Over six months , participants with NSCLC experienced decline in self-reported physical activity , 6MWD and muscle strength , and worsening symptoms . CONCLUSION At diagnosis individuals with NSCLC engage in less physical activity , are weaker and more depressed than healthy individuals and their self-reported physical activity declines over six months . Future studies are required to investigate the efficacy of interventions to increase physical activity Background Postoperative pulmonary complications ( PPC ) are the most frequently observed complications following lung resection , of which pneumonia and atelectasis are the most common . PPCs have a significant clinical and economic impact associated with increased observed number of deaths , morbidity , length of stay and associated cost . The aim of this study was to assess the incidence and impact of PPCs and to identify potentially modifiable independent risk factors . Methods A prospect i ve observational study was carried out on all patients following lung resection via thoracotomy in a regional thoracic centre over 13 months .  PPC was assessed using a scoring system based on chest x-ray , raised white cell count , fever , microbiology , purulent sputum and oxygen saturations . Results Thirty-four of 234 subjects ( 14.5 % ) had clinical evidence of PPC . The PPC patient group had a significantly longer length of stay ( LOS ) in hospital , high dependency unit ( HDU ) LOS , higher frequency of intensive care unit ( ITU ) admission and a higher number of hospital deaths . Older patients , body mass index ( BMI ) ≥30 kg/m2 , preoperative activity < 400 m , American Society of Anesthesiologists ( ASA ) score ≥3 , smoking history , chronic obstructive pulmonary disease ( COPD ) , lower preoperative forced expiratory volume in 1 s ( FEV1 ) and predicted postoperative ( PPO ) FEV1 were all significantly ( p<0.05 ) associated with PPC on univariate analysis . Multivariate analysis confirmed that age > 75 years , BMI ≥30 kg/m2 , ASA ≥3 , smoking history and COPD were significant independent risk factors in the development of PPC ( p<0.05 ) . Conclusion The clinical impact of PPCs is marked . Significant independent preoperative risk factors have been identified in current clinical practice . Potentially modifiable risk factors include BMI , smoking status and COPD . The impact of targeted therapy requires further evaluation Background Systemic inflammation plays an important role in the initiation , promotion , and progression of lung carcinogenesis . In patients with non-small cell lung cancer ( NSCLC ) , fibrinogen levels correlate with neoplasia . Here we compared the effects of pulmonary rehabilitation ( PR ) with chest physical therapy ( CPT ) on fibrinogen and albumin levels in patients with LC and previous inflammatory lung disease awaiting lung resection . Methods We conducted a r and omized clinical trial with 24 patients who were r and omly assigned to Pulmonary Rehabilitation ( PR ) and Chest Physical Therapy ( CPT ) groups . Each group underwent training 5 days weekly for 4 weeks . All patients were assessed before and after four weeks of training through clinical assessment , measurement of fibrinogen and albumin levels , spirometry , 6-minute Walk Test ( 6MWT ) , quality of life survey , and anxiety and depression scale . PR involved strength and endurance training , and CPT involved lung expansion techniques . Both groups attended educational classes . Results A mixed between-within subjects analysis of variance ( ANOVA ) revealed a significant interaction between time ( before and after intervention ) and group ( PR vs. CPT ) on fibrinogen levels ( F(1 , 22 ) = 0.57 , p < 0.0001 ) and a significant main effect of time ( F(1 , 22 ) = 0.68 , p = 0.004 ) . Changes in albumin levels were not statistically significant relative to the interaction effect between time and group ( F(1 , 22 ) = 0.96 , p = 0.37 ) nor the main effects of time ( F(1 , 22 ) = 1.00 , p = 1.00 ) and group ( F(1 , 22 ) = 0.59 , p = 0.45 ) . A mixed between-within subjects ANOVA revealed significant interaction effects between time and group for the peak work rate of the unsupported upper limb exercise ( F(1 , 22 ) = 0.77 , p = 0.02 ) , endurance time ( F(1 , 22 ) = 0.60 , p = 0.001 ) , levels of anxiety ( F(1 , 22 ) = 0.60 , p = 0.002 ) and depression ( F(1 , 22 ) = 0.74 , p = 0.02 ) , and the SF-36 physical component summary ( F(1 , 22 ) = 0.83 , p = 0.07 ) . Conclusion PR reduced serum fibrinogen levels , improved functional parameters , and quality of life of patients with LC and inflammatory lung disease awaiting lung resection . Trial registration Current Controlled Trials RBR-3nm5bv 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 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 Introduction Postoperative pulmonary complications ( PPC ) such as atelectasis and pneumonia are common following lung resection . PPCs have a significant clinical impact on postoperative morbidity and mortality . We studied the long-term effects of PPCs and sought to identify independent risk factors . Methods A prospect i ve observational study involved all patients following lung resection in a regional thoracic centre over 4 years .  PPCs were assessed daily in hospital using the Melbourne group scale based on chest X-ray , white cell count , fever , purulent sputum , microbiology , oxygen saturations , physician diagnosis and intensive therapy unit (ITU)/high-dependency unit readmission . Follow-up included hospital length of stay ( LOS ) , 30-day readmissions , and mortality . Results 86 of 670 patients ( 13 % ) who had undergone a lung resection developed a PPC . Those patients had a significantly longer hospital LOS in days ( 13 , 95 % CI 10.5–14.9 vs 6.3 , 95 % CI 5.9 to 6.7 ; p<0.001 ) and higher rates of ITU admissions ( 28 % vs 1.9 % ; p<0.001 ) and 30-day hospital readmissions ( 20.7 % vs 11.9 % ; p<0.05 ) . Significant independent risk factors for development of PPCs were COPD and smoking ( p<0.05 ) , not age . Excluding early postoperative deaths , developing a PPC result ed in a significantly reduced overall survival in months ( 40 , 95 % CI 34 to 44 vs 46 , 95 % CI 44 to 47 ; p=0.006 ) . Those who developed a PPC had a higher rate of non-cancer-related deaths ( 11 % vs 5 % ; p=0.020 ) . PPC is a significant independent risk factor for late deaths in non-small cell lung cancer patients ( HR 2.0 , 95 % CI 1.9 to 3.2 ; p=0.006 ) . Conclusions Developing a PPC after thoracic surgery is common and is associated with a poorer long-term outcome OBJECTIVE This study investigates whether targeted postoperative respiratory physiotherapy decreased the incidence of postoperative pulmonary complications and length of stay for patients undergoing elective pulmonary resection via open thoracotomy . METHODS Seventy-six patients participated in a prospect i ve , single-blind , parallel-group , r and omised trial with concealed allocation , assessor blinding and intention-to-treat analysis . Treatment group participants received daily respiratory physiotherapy interventions until discharge . Control group participants received st and ard medical/nursing care involving a clinical pathway . The presence of postoperative pulmonary complications was assessed on a daily basis during hospitalisation using a st and ardised diagnostic tool . Length of stay was recorded . RESULTS Postoperative pulmonary complications developed in two participants ( 4.8 % ) in the treatment group and in one participant ( 2.9 % ) in the control group ; the difference ( treatment minus control ) was 1.8 % ( 95 % confidence interval ( CI ) -10.6 % to 13.1 % ) ( p=1.00 ) . No significant difference was found between groups for length of stay ( treatment group , median 6.0 days ; control group 6.0 days ) ( p=0.87 ) . A preoperative forced expiratory volume in 1s of 1.5l or less ( p=0.005 ) and a history of chronic obstructive pulmonary disease ( p=0.008 ) were associated with a greater number of criteria for a postoperative pulmonary complication being met . CONCLUSIONS In this patient population , given the low incidence of postoperative
