Lai Y, et al. - In this prospective analysis of 725 patients who had lobectomy for non-small cell lung cancer (NSCLC), researchers investigated the association between peak expiratory flow (PEF) and postoperative pulmonary complications (PPCs). They analyzed patients’ basic characteristics and clinical data in the hospital. Findings demonstrated a significant correlation between a low PEF value and PPCs in this population. This implied that a low PEF could potentially be an independent risk factor for the PPC occurrence. A PPC-guided (PEF value ≤300 L/min) risk assessment could be valuable for perioperative management of lung cancer candidates waiting for surgery.
