{Abstract}: <B>OBJECTIVE: </B>Evaluation of the association of inflammatory cell ratios, especially neutrophil-to-lymphocyte ratio (NLR), based on preoperative complete blood counts, with postoperative complications in lobectomy surgery.<BR><B>METHODS: </B>This was a retrospective monocentric cohort study.<BR><B>METHODS: </B>The study was conducted at Foch University Hospital in Suresnes, France.<BR><B>METHODS: </B>Patients having undergone a scheduled lobectomy from January 2018 to September 2021.<BR><B>METHODS: </B>There were no interventions.<BR><B>RESULTS: </B>The authors studied 208 consecutive patients. Preoperative NLR, monocyte-to-lymphocyte ratio, platelet-to-lymphocyte ratio, systemic inflammation index, systemic inflammation response index, and aggregate inflammation systemic index were calculated. Median and (IQR) of NLR was 2.67 (1.92-3.69). No statistically significant association was observed between any index and the occurrence of at least one major postoperative complication, which occurred in 37% of the patients. Median postoperative length of stay was 7 (5-10) days. None of the ratios was associated with prolonged length of stay (LOS), defined as a LOS above the 75th percentile.<BR><B>CONCLUSIONS: </B>The results suggested that simple available inflammatory ratios are not useful for the preoperative identification of patients at risk of postoperative major complications in elective lobectomy surgery.
