Combining nutrition checks and muscle measurements to predict outcomes after lung cancer surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, single-center observational cohort of adults undergoing anatomical lung resection for primary non-small cell lung cancer. Nutritional status will be measured with serum biomarkers, inflammatory indices, and validated clinical nutrition scores, plus dietitian-led bioimpedance and functional testing. Sarcopenia will be measured from preoperative thoracic CT (muscle area and density) and ultrasound muscle thickness, with international consensus criteria applied. These multimodal measures will be related to postoperative complications, ICU need, length of stay, and short-term mortality.

Why it matters
