Abstract

Introduction: Sarcopenia negatively impacts surgical outcomes in gastrointestinal cancer patients, yet practical preoperative screening tools are lacking. The CRP/ALB ratio, a novel biomarker of systemic inflammation and nutritional status, may enhance sarcopenia prediction but remains underexplored in surgical oncology. This study aims to identify the predictors for preoperative sarcopenia prediction in gastric and colorectal cancer patients.

Methods: This retrospective study analyzed 145 patients undergoing curative surgery (2019-2021). Sarcopenia was defined by sex-specific CT-measured L3 skeletal muscle index (cutoffs, male ≤ 40.8 cm²/m²; female ≤ 34.9 cm²/m²). Multivariable logistic regression identified predictors, with model performance assessed via ROC analysis and Cohen's Kappa.

Results: The cohort (median age 64 years; 73.8% male) comprised 66 gastric (45.5%) and 79 colorectal (54.5%) cancer patients, with 29 (20%) diagnosed with sarcopenia. Sarcopenic patients exhibited a higher NRS 2002 score (P < 0.001), lower PNI score (P < 0.05), and higher CRP/ALB ratio (P < 0.05). Multivariate logistic regression analysis results showed that CRP/ALB ratio (OR = 3.084, 95% CI 1.071-8.882, P = 0.037), age (OR = 1.074, 95% CI 1.021-1.130, P = 0.006), and BMI (OR = 0.667, 95% CI 0.542-0.820, P = 0.000) were associated with the increased risk of sarcopenia. The combined model achieved superior discrimination (AUC = 0.854, 95% CI 0.770-0.937), yielding 75.86% sensitivity and 84.82% specificity at optimal cutoff value - 1.0340, and a Cohen's Kappa coefficient of 0.542 when compared to CT results.

Conclusion: The CRP/ALB ratio combined with BMI and age is utilized as a convenient and effective tool for preoperative sarcopenia screening. This model-driven approach provides robust strategies to facilitate preoperative interventions, optimize perioperative care, and enhance long-term oncological outcomes for patients undergoing gastric and colorectal cancer surgery.

期刊介绍： The Journal of Gastrointestinal Cancer is a multidisciplinary medium for the publication of novel research pertaining to cancers arising from the gastrointestinal tract.The journal is dedicated to the most rapid publication possible.The journal publishes papers in all relevant fields, emphasizing those studies that are helpful in understanding and treating cancers affecting the esophagus, stomach, liver, gallbladder and biliary tree, pancreas, small bowel, large bowel, rectum, and anus. In addition, the Journal of Gastrointestinal Cancer publishes basic and translational scientific information from studies providing insight into the etiology and progression of cancers affecting these organs. New insights are provided from diverse areas of research such as studies exploring pre-neoplastic states, risk factors, epidemiology, genetics, preclinical therapeutics, surgery, radiation therapy, novel medical therapeutics, clinical trials, and outcome studies.In addition to reports of original clinical and experimental studies, the journal also publishes: case reports, state-of-the-art reviews on topics of immediate interest or importance; invited articles analyzing particular areas of pancreatic research and knowledge; perspectives in which critical evaluation and conflicting opinions about current topics may be expressed; meeting highlights that summarize important points presented at recent meetings; abstracts of symposia and conferences; book reviews; hypotheses; Letters to the Editors; and other items of special interest, including:Complex Cases in GI Oncology: This is a new initiative to provide a forum to review and discuss the history and management of complex and involved gastrointestinal oncology cases. The format will be similar to a teaching case conference where a case vignette is presented and is followed by a series of questions and discussion points. A brief reference list supporting the points made in discussion would be expected.
