Introduction: The aim of this study is selecting the hub genes associated with hepatocellular carcinoma (HCC) to construct a Cox regression model for predicting prognosis in HCC patients.
Methods: Using HCC patient data from the ICGC and TCGA databases, screened for 40 core genes highly correlated with histological grade of HCC. Univariate and multivariate Cox regression analyses were performed on the genes highly associated with HCC prognosis, and the model was established. The expression of those genes was measured by immunohistochemistry in 110 HCC patients who underwent the surgery in the First Affiliated Hospital of Wenzhou Medical University. The survival of HCC patients was analyzed by the Kaplan-Meier method.
Results: Eight genes (CDC45, CENPA, MCM10, MELK, CDC20, ASF1B, FANCD2, and NCAPH) were correlated with prognosis, and the same result was observed in 110 HCC patients. Using the regression model, the HCC patients in the training set were classified as high- and low-risk groups. The overall survival of patients in the high-risk group was shorter than that in the low-risk group, and the same results were obtained in the verification set.
Conclusion: This study found that the risk model according to these 8 genes can be used as a predictor of prognosis in HCC. These genes may become alternative biomarkers and therapeutic targets and provide new therapeutic strategies for HCC.
Introduction: Although the relationship between systemic inflammatory responses and prognosis has been known in various cancers, it remains unclear which scores are most valuable for determining the prognosis of extrahepatic cholangiocarcinoma. We aimed to verify the usefulness of various inflammation-based scores as prognostic factors in patients with resected extrahepatic cholangiocarcinoma.
Methods: We analyzed consecutive patients undergoing surgical resection for extrahepatic cholangiocarcinoma at our institution between January 2000 and December 2019. The usefulness of the following inflammation-based scores as prognostic factor was investigated: glasgow prognostic score (GPS), modified GPS, neutrophil-to-lymphocyte ratio, platelet to lymphocyte ratio, lymphocyte-to-monocyte ratio, prognostic nutrition index, C-reactive protein to albumin ratio (CAR), controlling nutritional status (CONUT), and prognostic index.
Results: A total of 169 patients were enrolled in this study. Of the nine scores, CAR and CONUT indicated prognostic value. Furthermore, multivariate analysis for overall survival revealed that high CAR (>0.23) was an independent prognostic factor (hazard ratio: 1.816, 95% confidence interval: 1.135-2.906, p = 0.0129), along with lymph node metastasis and curability. There was no difference in tumor staging and short-term outcomes between the low CAR (≤0.23) and high CAR groups.
Conclusions: CAR was the most valuable prognostic score in patients with resected extrahepatic cholangiocarcinoma.
