Abstract
Objective: Cachexia occurs in approximately half of hepatocellular carcinoma (HCC) patients as the disease progresses and is correlated with a poor prognosis. Therefore, early identification of HCC patients at risk of developing cachexia and their prognosis is crucial. This study investigated the functional liver imaging score (FLIS) derived from gadoxetic acid-enhanced magnetic resonance imaging (MRI) to identify cachexia in HCC patients and their prognosis.
Methods: Pretreatment clinical and MRI data from 339 HCC patients who underwent gadoxetic acid-enhanced MRI scans were retrospectively collected. Patient weights were recorded for 6 months following the MRI scan to diagnose cachexia. The FLIS was calculated as the sum of the enhancement quality score, the excretion quality score, and the portal vein sign quality score. A Cox proportional hazards model was used to determine the significant factors affecting overall survival (OS). Multivariable logistic regression was then conducted to identify variables predicting cachexia in HCC patients, which were subsequently used to predict OS.
Results: Cox regression analysis revealed a significant association between cachexia and worse OS. Both FLIS (0-4 vs. 5-6 points) (OR, 9.20; 95% CI: 4.68-18.10; P<0.001) and α-fetoprotein >100 ng/mL (OR, 4.08; 95% CI: 2.13-7.83; P<0.001) emerged as significant predictors of cachexia in patients with HCC. Furthermore, FLIS (0-4 vs. 5-6 points) (HR, 1.73; 95% CI: 1.19-2.51; P=0.004) was significantly associated with OS. Patients in the FLIS 0-4 points group had shorter OS than those in the FLIS 5-6 points group [20 months (95% CI, 14.7-25.3) vs. 43 months (95% CI, 27.7-58.3); P=0.001].
Conclusion: Cachexia was associated with worse OS. The functional liver imaging score emerged as a significant predictor of cachexia in HCC patients and their prognosis.
期刊介绍:
Current Medical Science provides a forum for peer-reviewed papers in the medical sciences, to promote academic exchange between Chinese researchers and doctors and their foreign counterparts. The journal covers the subjects of biomedicine such as physiology, biochemistry, molecular biology, pharmacology, pathology and pathophysiology, etc., and clinical research, such as surgery, internal medicine, obstetrics and gynecology, pediatrics and otorhinolaryngology etc. The articles appearing in Current Medical Science are mainly in English, with a very small number of its papers in German, to pay tribute to its German founder. This journal is the only medical periodical in Western languages sponsored by an educational institution located in the central part of China.
