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 .
Preoperative pulmonary rehabilitation in patients with non-small cell lung cancer and chronic obstructive pulmonary disease
Introduction The aim of this study was to assess the effects of preoperative pulmonary rehabilitation ( PPR ) on preoperative clinical status changes in patients with chronic obstructive pulmonary disease ( COPD ) and non-small cell lung cancer ( NSCLC ) , and net effects of PPR and cancer resection on residual pulmonary function and functional capacity . Material and methods This prospect i ve single group study included 83 COPD patients ( 62 ±8 years , 85 % males , FEV1 = 1844 ±618 ml , Tiffeneau index = 54 ±9 % ) with NSCLC , on 2–4-week PPR , before resection . Pulmonary function , and functional and symptom status were evaluated by  spirometry , 6-minute walking distance ( 6MWD ) and Borg scale , on admission , after PPR and after surgery . Results Following PPR significant improvement was registered in the majority of spirometry parameters ( FEV1 by 374 ml , p < 0.001 ; VLC by 407 ml , p < 0.001 ; FEF50 by 3 % , p = 0.003 ) , 6MWD ( for 56 m , p < 0.001 ) and dyspnoeal symptoms ( by 1.0 Borg unit , p < 0.001 ) . A positive correlation was identified between preoperative increments of FEV1 and 6MWD ( r s = 0.503 , p = 0.001 ) . Negative correlations were found between basal FEV1 and its percentage increment ( r s = –0.479 , p = 0.001 ) and between basal 6MWD and its percentage change ( r s = –0.603 , p < 0.001 ) during PPR . Compared to basal values , after resection a significant reduction of most spirometry parameters and 6MWD were recorded , while Tiffeneau index , FEF25 and dyspnoea severity remained stable ( p = NS ) . Conclusions Preoperative pulmonary rehabilitation significantly enhances clinical status of COPD patients before NSCLC resection . Preoperative increase of exercise tolerance was the result of pulmonary function improvement during PPR . The beneficial effects of PPR were most emphasized in patients with initially the worst pulmonary function and the weakest functional capacity
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
