The Significance of Controlling Nutritional Status (CONUT) Score as a Novel Prognostic Parameter in Small Cell Lung Cancer

Purpose The immuno-nutritional status is closely related to the prognosis in many cancers. Controlling nutritional status (CONUT) score is a new parameter that reflects the immuno-nutritional status and is prognostic in some cancers. However, the prognostic significance of the CONUT score in small cell lung cancer (SCLC) is unknown. We aimed to demonstrate the prognostic significance of the CONUT score in patients with SCLC. Methods Two hundred sixteen patients who were followed up with SCLC were included in the study retrospectively. According to the receiver operating characteristic (ROC) curve analysis, the optimal cutoff values were determined for the CONUT score, and the patients were divided into low (
