Low Thoracic Skeletal Muscle Area Predicts Morbidity After Pneumonectomy for Lung Cancer.

Background: Sarcopenia represented by low psoas muscle area is associated with increased hospital length of stay (LOS), postoperative complications, and mortality. We studied whether thoracic skeletal muscle area (TSMA) derived from computed tomography (CT) predicts morbidity after pneumonectomy for lung cancer.

Methods: Consecutive patients who underwent pneumonectomy for lung cancer from 2005 to 2017 were retrospectively analyzed.

Preoperative thoracic muscle area on computed tomography predicts long-term survival following pneumonectomy for lung cancer.

Objectives: To assess the prognostic role of thoracic muscle as quantified on preoperative computed tomography (CT) for the estimation of overall survival (OS) following pneumonectomy.

Methods: Muscle cross-sectional area (CSA) at the level of the fifth (T5) and eighth (T8) thoracic vertebra was measured on CT scans of consecutive patients with lung cancer prior to pneumonectomy. We stratified patients into high and low muscle groups using the gender-specific median of muscle CSA as separator and estimated associations of muscle CSA and OS using the Kaplan-Meier analysis.

Thoracic Skeletal Muscle Is Associated With Adverse Outcomes After Lobectomy for Lung Cancer.

Background: Assessment of risk associated with lung cancer resection is primarily based on evaluation of cardiopulmonary function and remains imprecise. We investigated the relationship between thoracic muscle and early outcomes after lobectomy.

Methods: Cross-sectional area of skeletal muscle was measured at the level of the fifth thoracic vertebra on computed tomography in 135 consecutive patients before lobectomy for lung cancer.
