The pectoralis major index: a novel computed tomography biomarker for low thoracic muscle mass and eastern cooperative oncology group performance status in lung cancer patients
T4-level muscle metrics showed good internal discrimination for lung cancer-related low thoracic muscle mass across sex and disease stage, with the pectoralis major index achieving the highest overall performance. Moreover, the pectoralis major index may be a potential imaging biomarker associated with ECOG performance status.
