Effect of thoracotomy and lung resection on exercise capacity in patients with lung cancer

Abstract: Background-Resection is the treatment of choice for lung cancer, but may cause impaired cardiopulmonary function with an adverse eVect on quality of life. Few studies have considered the eVects of thoracotomy alone on lung function, and whether the operation itself can impair subsequent exercise capacity. Methods-Patients being considered for lung resection (n = 106) underwent full static and dynamic pulmonary function testing which was repeated 3-6 months after surgery (n = 53). Results-Thoracotomy alone (n =… Show more

“…The residual function (FEV1, DL,CO and VO 2 , peak) may reach values as high as 90-95% of preoperative values 3-6 months after operation. Conversely, after pneumonectomy, the loss in pulmonary function and exercise capacity is larger (20-30% at 6 months) and substantially stable over time [54,64,65,[192][193][194][195]. In general, exercise tolerance displays a more complete recovery compared to airflow and gas exchange capacities, presumably due to other compensatory mechanisms related to the cardiovascular system and the peripheral oxygen extraction capacity [54,64,194].…”

“…Postoperative cardiopulmonary function and exercise capacity have been examined following pulmonary resection and demonstrated to be persistently decreased only after pneumonectomy (11,12). The impairment of respiratory function after a pneumonectomy may be explained by overdistention and emphysematous changes of the contralateral lung (which may show evidence of histological hyperplasia and loss of elasticity), an increase in the airway resistance resulting in alveolar gas mixing, arterial desaturation or late pulmonary failure.…”

“…Patients who undergo surgical therapy for their lung cancer should not expect severe debilitation postoperatively. With appropriate preoperative evaluation and peri-and postoperative care, only patients who have undergone pneumonectomies can expect impaired exercise performance [9]. In a group of 77 patients who had surgical intervention for lung cancer, patients who had pneumonectomies had a decline in exercise capacity of 28% (maximal oxygen uptake declined 28%) [9].…”
