Article Abstract
Purpose: This study aimed to evaluate the prognostic significance of the preoperative Controlling Nutritional Status (CONUT) score in head and neck squamous cell carcinoma (HNSCC).
Methods: Patients with HNSCC who underwent radical surgery between 2008 and 2017 were retrospectively analyzed and randomly divided into training and validation cohorts by 3:1 ratio. The CONUT score, based on serum albumin, total cholesterol, and lymphocyte count measured within 1 week before surgery, was used. Univariate and multivariate Cox regression identified survival-related variables, forming the basis for predictive models developed in the training cohort and validated in the validation cohort.
Results: A total of 636 patients were enrolled in this study, including 477 patients in the training cohort and 159 patients in validation cohort. A CONUT cutoff value of 2 effectively stratified patients into two distinct prognostic groups with significant survival differences in both the training and validation cohorts. In the multivariate Cox model, a high CONUT score emerged as an independent negative prognosticator of overall survival (OS) and cancer specific survival (CSS) in both training and validation cohorts. The CONUT score-based nomograms accurately predicted OS (concordance index: 0.778 in training cohort and 0.709 in validation cohort) and CSS (concordance index: 0.830 in training cohort and 0.778 in validation cohort).
Conclusion: The preoperative CONUT score is a useful prognostic marker for surgically treated HNSCC, enhancing nomogram-based risk models to identify high-risk patients and guide treatment decisions effectively.

Background: The Naples Prognostic Score (NPS) is a composite index that combines serum albumin (ALB), total cholesterol (TC), neutrophil-to-lymphocyte ratio (NLR), and lymphocyte-to-monocyte ratio (LMR). It has proven prognostic value across various cancers. However, its use in oral squamous cell carcinoma (OSCC) has not been sufficiently recognized for disease-specific characteristics.

Objective: The controlling nutritional status (CONUT) score, calculated using serum albumin, total cholesterol, and lymphocyte count, is an effective predictor of post-operative complications (PC) following oncologic resections in gastrointestinal system cancers. This retrospective study aimed to investigate the impact of pre-operative CONUT scores on overall post-operative complications (OPC) in patients with stage I-III gastric cancer (GC) who underwent gastrectomy.
Material And Methods: Patients who underwent curative gastric resection for GC between January 2013 and December 2024 were retrospectively analyzed.

Malnutrition is a prevalent but underrecognized condition in cardiovascular disease (CVD) patients, associated with adverse outcomes including longer hospitalizations, higher readmission rates, and increased mortality. Traditional measures such as body mass index (BMI) often fail to detect malnutrition, especially in patients with fluid retention, sarcopenia, or obesity. : This review critically examines current tools used to assess nutritional status in CVD populations.

Background: Nutritional risk assessment indices impact disease prognosis, yet their prognostic roles in preoperative digestive system tumor (DST) patients remain unclear.
Methods: In this study, the Controlling Nutritional Status (CONUT) score, the Nutritional Risk Index (NRI) and the Prognostic Nutritional Index (PNI) before surgery were applied to 17, 338 patients with 10 kinds of newly diagnosed DSTs. The distribution of nutritional risk and its correlation with mortality were examined in this study through the utilization of three nutritional risk assessment indices.
