Can functional inoperability in lung cancer patients be changed by pulmonary rehabilitation?

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. 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. After pulmonary rehabilitation, there was statistically significant improvement in the six-minute walking distance (53 m, p
