Abstract
BACKGROUND: This study aims to investigate the effects of shortterm intense pulmonary rehabilitation on respiratory function in patients with lung cancer who were defined as inoperable due to insufficient pulmonary reserve. METHODS: A total of 25 patients (24 males, 1 female; mean age 62 years; range, 50 to 72 years) who were histologically diagnosed as non-small cell lung carcinoma, considered functionally inoperable due to high risk of an estimated postoperative complication, and suitable for surgical resection according to tumor stage were included in the study. Patients received chest physiotherapy, self-walking and inspiratory muscle training for two weeks. The forced expiratory volume in one second, forced vital capacity, modified Medical Research Council dyspnea scale, six-minute walking distance, maximal inspiratory and expiratory pressures for respiratory muscle strength measurements, and predicted peak maximal oxygen consumption were examined. RESULTS: After pulmonary rehabilitation, there was statistically significant improvement in the six-minute walking distance (53 m, p<0.001), dyspnea perception (p<0.001), maximal inspiratory pressure (12 cm H2O, p<0.001), forced vital capacity (p<0.001), predicted forced expiratory volume in one second (%) (p=0.001), forced expiratory volume in one second (Δ forced expiratory volume in one second= 150 mL, p=0.001; Δ maximum value of forced expiratory volume in one second: 650 mL), and predicted maximal oxygen consumption (p<0.001). At the end of the rehabilitation, 60% of the patients (n=15) reevaluated by the surgeons could be operated. CONCLUSION: Short-term intensive pulmonary rehabilitation improves lung functions and exercise capacity while decreasing dyspnea perception. In our study, thanks to the gains derived from the exercise, approximately more than half of the patients could be operated. Therefore, it may be useful to refer patients to rehabilitation before establishing a decision of inoperability.
