In this study, we analyzed body composition through bioelectrical impedance analysis (BIA) and biochemical parameters such as glycemic and lipidic profile, inflammation profile and adiponectin serum levels in 30 patients (19 male; 11 women) undergoing video‐assisted thoracoscopic surgery (VATS) lobectomy for lung cancer from September 2021 to May 2022 at the Thoracic Unit of Luigi Vanvitelli University of Naples. The gene discussed is ADIPOQ; the disease is lung cancer.
