Objective:
The CT/MRI Liver Imaging Reporting and Data System (LI-RADS) demonstrates high specificity with relatively limited sensitivity for diagnosing hepatocellular carcinoma (HCC) in high-risk patients. This study aimed to explore the possibility of improving sensitivity by combining CT/MRI LI-RADS v2018 with second-line contrast-enhanced ultrasound (CEUS) LI-RADS v2017 using sulfur hexafluoride (SHF) or perfluorobutane (PFB).
Materials and Methods:
This retrospective analysis of prospectively collected multicenter data included high-risk patients with treatment-naive hepatic observations. The reference standard was pathological confirmation or a composite reference standard (only for benign lesions). Each participant underwent concurrent CT/MRI, SHF-enhanced US, and PFB-enhanced US examinations. The diagnostic performances for HCC of CT/MRI LI-RADS alone and three combination strategies (combining CT/ MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or a modified algorithm incorporating the Kupffer-phase findings for PFB [modified PFB]) were evaluated. For the three combination strategies, apart from the CT/MRI LR-5 criteria, HCC was diagnosed if CT/MRI LR-3 or LR-4 observations met the LR-5 criteria using LI-RADS SHF, LI-RADS PFB, or modified PFB.
Results:
In total, 281 participants (237 males; mean age, 55 ± 11 years) with 306 observations (227 HCCs, 40 non-HCC malignancies, and 39 benign lesions) were included. Using LI-RADS SHF, LI-RADS PFB, and modified PFB, 20, 23, and 31 CT/MRI LR-3/4 observations, respectively, were reclassified as LR-5, and all were pathologically confirmed as HCCs. Compared to CT/MRI LI-RADS alone (74%, 95% confidence interval [CI]: 68%–79%), the three combination strategies combining CT/MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or modified PFB increased sensitivity (83% [95% CI: 77%–87%], 84% [95% CI: 79%–89%], 88% [95% CI: 83%–92%], respectively; all P < 0.001), while maintaining the specificity at 92% (95% CI: 84%–97%).
Conclusion
The combination of CT/MRI LI-RADS with second-line CEUS using SHF or PFB improved the sensitivity of HCC diagnosis without compromising specificity.

BACKGROUND:A previous study by our group found that protein phosphatase 2Cm(PP2Cm)null mice developed significantly fewer symptoms of renal failure relative to wild-type mice,and thus it was speculated that PP2Cm may play an important protective role in the development of renal fibrosis,however,the molecular mechanisms remain undefined. OBJECTIVE:To investigate the effect of the PP2Cm gene on the transcriptome of human renal tubular epithelial cells. METHODS:Cultured human renal tubular epithelial cells were transfected with the PP2Cm gene into human renal tubular epithelial cells using plasmids.The expression of PP2Cm in the cells was detected by fluorescence quantitative PCR assay and western blot assay,and subsequently,cell RNA was separately extracted for transcriptome sequencing to look for differentially expressed genes between transfected and control groups.The resulting differential genes were further subjected to GO analysis and KEGG analysis using bioinformatics methods. RESULTS AND CONCLUSION:There were 796 differentially expressed genes,553 of which were downregulated genes and 243 upregulated genes,in human renal tubular epithelial cells transfected with the PP2Cm gene compared with untransfected blank cells by sequencing analysis.GO analysis results showed that the upregulated genes were significantly enriched in cellular biosynthetic processes,protein translation,intrinsic apoptotic signaling pathways,and so on.The downregulated expressed genes were significantly enriched in endothelial cell proliferation,cell adhesion and other signaling pathways.KEGG analysis results showed that the significantly up-regulated genes were enriched in metabolism-related signaling pathways such as amino acid metabolism and biosynthesis.The downregulated expressed genes were significantly enriched in signaling pathways such as pantothenate and coenzyme A biosynthesis.Our results show that PP2Cm overexpression can affect a number of signaling pathways related to a range of biological processes in renal tubular epithelial cells,which may be important in metabolism-related signaling pathways such as amino acid metabolism and biosynthesis.
