The role of ceus in characterization of superficial lymph nodes : a single center prospective study

Accurate lymph node characterization is important in a large number of clinical settings. We evaluated the usefulness of Contrast Enhanced Ultrasound (CEUS) in distinguishing between benign and malignant lymph nodes compared with conventional ultrasonography in the differential diagnosis of superficial lymphadenopathy.We present our experience for 111 patients enrolled in a single center.111 superficial lymph nodes were selected and only 1 lymph node per patient underwent CEUS. A definitive diagnosis for all lymph nodes was obtained by ultrasonographically guided biopsy and/or excision biopsy.The size of the lymph nodes, the site (neck, axilla, inguinal region) being easily accessible for biopsy, and the US and color Doppler US characteristics guided us in selecting the nodes to be evaluated by CEUS.In our study we identified different enhancement patterns in benign and malignant lymph nodes, with a high degree of diagnostic accuracy for superficial lymphadenopathy in comparison with conventional US

Sorafenib off-target effects predict outcomes in patients treated for hepatocellular carcinoma

Correlation Between the Hepatic Expression of Human MicroRNA hsa-miR-125a-5p and the Progression of Fibrosis in Patients With Overt and Occult HBV Infection

AimsTo evaluate the correlation between the hepatic expression pattern of hsa-miR-125a-5p and HBV-DNA and the progression of fibrosis in patients with overt or occult HBV infection.MethodsWe enrolled all the HBsAg-positive treatment naive patients (overt HBV group) and all the HBsAg-negative patients with hepatocellular carcinoma and with a positive HBV-DNA in their hepatic tissue (occult HBV group), who underwent a diagnostic liver biopsy between April 2007 and April 2015. Tissue concentrations of HBV-DNA and hsa-miR-125a-5p were then analyzed by real-time quantitative PCR. Necroinflammatory activity and fibrosis were evaluated according to the Ishak score.ResultsDuring the study period, we enrolled 64 patients with overt and 10 patients with occult HBV infection. In the overt HBV group, 35 of 64 (54.7%) showed a mild fibrosis (staging 0–2), 17 (26.6%) a moderate fibrosis (staging 3–4), while the remaining 12 (18.7%) had a cirrhosis. All patients in the occult HBV group were cirrhotic. Patients with more advanced fibrosis stage showed a higher mean age when compared with those with mild (p < 0.00001) or moderate fibrosis (p < 0.00001) and were more frequently male than patients with staging 0–2 (p = 0.04). Similarly, patients with occult B infection were older than HBsAg-positive patients. Liver concentrations of miR-125a-5p were significantly higher in patients with cirrhosis (9.75 ± 4.42 AU) when compared with patients with mild (1.39 ± 0.94, p = 0.0002) or moderate fibrosis (2.43 ± 2.18, p = 0.0006) and were moderately higher in occult than in overt HBV infection (p = 0.09). Moreover, we found an inverse correlation, although not statistically significant, between the tissue HBV-DNA levels and the staging of fibrosis.ConclusionThis study suggests a correlation between the tissue expression of hsa-miR-125a-5p and the progression of liver damage in a group of patients with occult or overt HBV infection. If confirmed, these data suggest the hsa-miR-125a-5p may be a novel biomarker of hepatic damage

Clinical Features of Patients with Home Isolation Sars-Cov-2 Infection: A Multicenter Retrospective Study in Southern Italy

To describe epidemiological and clinical features of patients confirmed as having SARS-CoV-2 infection and managed in isolation at home. We performed a multicenter retrospective study enrolling all SARS-CoV-2-positive adults evaluated from 28 February to 31 May 2020 at one of nine COVID-19 Units in southern Italy: we included patients receiving care at home and those admitted to hospital. We defined patients with not-severe disease if they were asymptomatic or experienced a mild infection that did not need oxygen (O2) therapy and those with a severe infection if hospitalized and required O2 therapy. We enrolled 415 patients with SARS-CoV-2 infection: 77 were managed in isolation at home, 338 required hospital management. The 77 patients in home isolation were less frequently male than hospitalized patients (55% vs. 64%; <0.01) and were younger (median age 45 years (IQR:19) vs. 62 (IQR 22); p < 0.01), had a lower Charlson comorbidity index (median 0 (IQR2) vs. 6 (IQR 3); p < 0.01), and included fewer subjects with an underlying chronic disease (36% vs. 59%; p < 0.01). According to a binomial logistic regression analysis, a younger age (OR: 0.96 (95% IC: 0.94–0.98), p < 0.01) and a low Charlson comorbidity index (OR: 0.66 (95% IC: 0.54–0.83); p < 0.01) were independent factors associated with at-home management. The identification of subjects with SARS-CoV-2 infection who could be managed in home isolation is useful in clinical practice. A younger age and no comorbidities were identified as factors independently associated with home management

Development of a risk score to predict portal vein tumor thrombosis in patients with hepatocellular carcinoma

Background: Portal vein tumor thrombosis (PVTT) is a common complication of hepatocellular carcinoma and is one of the most negative prognostic factors. The management of patients with PVTT is challenging. The aim of the study was to develop a score predictive of tumor thrombosis. Methods: Data from a large cohort of 2243 hepatocellular carcinoma patients (all stages) recorded in the Progetto Epatocarcinoma Campania (January 2013-April 2021) database were analyzed. To construct the score, univariate generalized estimated equation models, the bootstrap approach for internal validation, and a regression coefficient-based scoring system were used. Results: PVTT (any location) was found in 14.4% of cases and was related to shorter survival. Males, younger patients, and symptomatic cases were more prevalent among the PVTT group. At multivariate analysis, size ≥5 cm, massive or infiltrative hepatocellular carcinoma growth, and alpha-fetoprotein ≥400 ng/mL were significantly associated with PVTT. A risk prediction score of PVTT based on eight variables was developed. Using a continuous score, the risk was associated with an odds ratio (OR) of 1.30 (1.27-1.34; P  8 versus a score ≤8 the OR for PVTT was 11.33 (8.55-15.00; P  < 0.001). Conclusion: The risk score for PVTT might be useful for clinicians to optimize hepatocellular carcinoma management by picking out patients with more aggressive cancers and higher mortality rates. Prospective validation of the score is needed before its application in daily clinical practice

Multicenter prospective study of angiogenesis polymorphism validation in HCC patients treated with sorafenib. An Innovate study protocol

Although sorafenib is the upfront standard of care for advanced hepatocellular carcinoma (HCC), molecular predictors of efficacy have not been identified yet. In the ALICE-1 study, rs2010963 of VEGF-A and VEGF-C proved to be independent predictive factors for progression-free survival (PFS) and overall survival (OS) in multivariate analysis. The ALICE-1 study results were confirmed in the ALICE-2 study, in which VEGF and VEGFR SNPs were analyzed. In the ePHAS study we analyzed the SNPs of eNOS. In univariate analysis, patients homozygous for an eNOS haplotype (HT1: T-4b at eNOS-786/eNOS VNTR) had significantly shorter median PFS and OS than those with other haplotypes. These data were confirmed in the validation set
