Postoperative rehabilitation Although surgery is the main curative therapy for lung cancer, the procedure can directly cause a reduction in pulmonary functional reserve and exercise capacity proportional to the extent of resection. The problems might be more severe in those undergoing multimodality treatments or who have co-morbidity. Across various studies, indices such as FEV1, FVC, TLC, DLCO and VO2 peak are negatively affected by thoracic surgery. Patients with lung cancer who underwent segmentectomy had better pulmonary function after surgery than those who underwent lobectomy at 3–12 months postoperatively. However, a marginally significant benefit was observed in segmentectomy group for further info threshold when compared to lobectomy. There was a positive and significant correlation between the number of resected segments versus loss of both FVC and FEV1 at six months. The loss of lung function also varied significantly with the location of the resection, comorbidity and methods of operation. For example, resection of an emphysematous portion of the lung will probably result a reduced loss of function. Patients with COPD typically experience smaller declines in FEV1 after lobectomy than those without COPD. Declines in DLCO and VO2 peak are more variable, with the reported decrease of 3–20% in those with COPD, and 0–21% in those without the disease. Such reduction persisted up to three years after surgery, while the values still remained lower than the preoperative values. When divided lobectomy into two groups: the upper lobectomy (UL) group and the lower lobectomy (LL) group, FVC of the LL group decreased more significantly from two weeks to six months after the operation compared with the UL group. There were no differences at 12 months after resection between the two groups nor in FEV1. A recent study showed that the actual percent-of-predicted FEV1 and DLCO one month after surgery were almost equal to the predicted postoperative value, and the number continued to increase significantly six to 12 months after training. However, no improvement was observed on the same actual pulmonary functional tests in subjects with COPD, or in those who underwent thoracotomy or received adjuvant chemotherapy after one year of training. In light of those factors that contribute to muscle deconditioning, and ultimately to physical inactivity, the training exercise should play a key role in preventing or at least mitigating the harmful effects of surgery. Rehabilitation following surgery aims to restore physical status and to maximize function, physical activity, psychological status and health-related quality of life. Nevertheless, only a few studies on Hydrophobic groups topic have been performed and are generally based on a small number of patients. In 2014, a systematic review aimed to synthesize all available evidence with regard to exercise intervention for patients who were surgically treated for NSCLC. The results illustrated only 20 studies across the spectrum being considered eligible for the review, and most selected studies were observational single group trials. Generally, rehabilitation programs are supervised, which range from 4 to 14 weeks in an outpatient setting, although inpatient and home-based programs have also been used. A majority of the studies included both aerobic (walking, treadmill and/or stationary cycle) and resistance training components. Other components such as breathing exercises, dyspnea management, balance exercises and limb stretches were used occasionally; however, the independent contribution of these training components to the resultant outcomes is unknown. The authors found that the outcomes measured in pulmonary function, including FEV1, DLCO and FVC, showed insignificant results for all pulmonary function measures in six of the ten studies except only four studies reported an improved pulmonary function. All but one of the studies that used the 6 MWT test reported a significant increase in distance measured from baseline to post intervention, which increased from 28 m to 377 m. Studies focusing on the cardiopulmonary exercise test reported a significant increase in exercise capacity in three of the five studies, with VO2 max improving from 2.8 to 6.3 mL/kg/min. One study showed that the highest percentage of improvement was twice as long in the duration of intervention (eight weeks compared to four weeks). Studies that recruited patients who had impaired exercise capacity at baseline (VO2 max < 15 mL/kg/min) showed the most improvement in post-exercise interventions.
