However whether these inflammation-scores improves the prognostication per formed by well-established prognostic markers is unsettled. In a large register-based lung cancer patient cohort nine different inflammation-scores were compared and their ability to optimize the prognostication of OS was evaluated. Methods Lung cancer patients diagnosed from 2009 2018 in The Central Denmark Region were identified in the Danish Lung Cancer Registry. Pre-treatment inflammation markers were extracted from the clinical laboratory information system. Prognostication of OS was evaluated by Cox proportional hazard models. Comparison of the inflammation-scores and their added value to established prognostic markers were assessed by Akaike s information criteria and Harrel s C-index. Results In total 5 320 patients with non-small cell lung cancer NSCLC and 890 patients with small cell lung cancer SCLC were identified. In NSCLC the Aarhus composite biomarker score ACBS including albumin C-reactive protein neutrophil count lymphocyte count and haemoglobin and the neutrophil-lymphocyte-ratio NLR were superior. Furthermore they improved the prognostication of OS significantly p Winther Larsen et al. BMC Cancer 2022 22 63 Page 2 of 10 proven clinically relevant.
