Criterion validity for three of these measures was established in NSCLC but not the reliability or responsiveness .
Background The measurement properties of instruments used to assess functional capacity , physical activity and muscle strength in participants with non-small cell lung cancer ( NSCLC ) have not been systematic ally review ed .
Method Objectives : To identify outcome measures used to assess these outcomes in participants with NSCLC ; and to evaluate , synthesis e and compare the measurement properties of the outcome measures identified .
Predictors of exercise oxygen desaturation following major lung resection.
OBJECTIVE To identify predictors of postoperative exercise oxygen desaturation ( EOD ) in patients su bmi tted to lobectomy or pneumonectomy for lung carcinoma . PATIENTS AND METHODS A consecutive series of 227 patients with non-small cell lung cancer su bmi tted to lobectomy or pneumonectomy from January 2000 through October 2002 were prospect ively analyzed . Maximal stair-climbing tests were performed preoperatively ( the day before the operation ) and postoperatively ( on average , 9.2 days after operation ) in room air for all patients . A fall in oxygen saturation during the exercise below 90 % was termed ' desaturation ' . Univariate and multivariate analyses were performed to identify predictors of postoperative EOD . RESULTS Thirty-five patients ( 15.4 % ) developed postoperative EOD . After multivariate analysis , the only independent predictor of postoperative EOD result ed a reduction in oxygen saturation during the preoperative exercise ( P=0.0004 ) . CONCLUSIONS Patients with a reduction in oxygen saturation during the preoperative exercise test are at increased risk to develop a postoperative EOD below 90 % . A postoperative exercise test should be performed in all these patients . Should EOD be confirmed , an intermittent home oxygen therapy is recommended in order to facilitate recovery from operation and improve the quality of life
