AIM To compare features of hepatocellular carcinoma(HCC) in Hispanics to those of African Americans and *** Patients treated for HCC at an urban tertiary medical center from 2005 to 2011 were identified from a tumor registry. Data were collected retrospectively, including demographics, comorbidities, liver disease characteristics, tumor parameters, treatment, and survival(OS) outcomes. OS analyses were performed using Kaplan-Meier *** One hundred and ninety-five patients with HCC were identified: 80.5% were male, and 22% were age 65 or older. Mean age at HCC diagnosis was 59.7 ± 9.8 years. Sixty-one point five percent of patients had Medicare or Medicaid; 4.1% were uninsured. Compared to African American(31.2%) and White(46.2%) patients, Hispanic patients(22.6%) were more likely to have diabetes(P = 0.0019), hyperlipidemia(P = 0.0001), nonalcoholic steatohepatitis(NASH)(P = 0.0021), end stage renal disease(P = 0.0057), and less likely to have hepatitis C virus(P < 0.0001) or a smoking history(P < 0.0001). Compared to African Americans, Hispanics were more likely to meet criteria for metabolic syndrome(P = 0.0491), had higher median MELD scores(P = 0.0159), ascites(P = 0.008), and encephalopathy(P = 0.0087). Hispanic patients with HCC had shorter OS than the other racial groups(P = 0.020), despite similarities in HCC parameters and treatment. CONCLUSION In conclusion, Hispanic patients with HCC have higher incidence of modifiable metabolic risk factors including NASH, and shorter OS than African American and White patients.

Advanced computed tomography (CT) technology has allowed for faster and more robust imaging. However, it has been a technical challenge to correctly synchronize CT acquisition with adequate and uniform arterial enhancement in the entire peripheral arterial tree. In this summary, we introduce a method of injection/acquisition optimization strategy based on a velocity-compen-sated CT angiography technique for the peripheral artery system, which is currently used in the United States. We believe that this imaging technique will provide additional information for our daily CT services in China.

Current diagnostic approach to patients with adnexal masses: which tools are relevant in routine praxis?

Chinese Journal of Cancer Research 2013年第1期25卷 55-62页

Terzic Jelena Dotlic Ivana Likic Nebojsa Ladjevic Natasa Brndusic Nebojsa Arsenovic Sanja Maricic Tihomir Mihailovic Sasa Andrijasevic Clinic of Obstetrics and Gynecology Clinical Center of Serbia School of Medicine University of Belgrade Center for anesthesiology and resuscitation Clinical Center of Serbia Department of Cellular Pathology PathLinks Pathology Services Lincoln County Hospital Occupational Health Department General Health Center "Savski Venac" Department of radiology Ultramedica Clinic American Medical Academy

Objective： The aim of the study was to investigate which anamnestic, laboratory and ultrasound parameters used in routine practice could predict the nature of adnexal mass, thus enabling referral to relevant specialist. Methods： Study involved the women treated for adnexal tumors throughout a period of 2 years. On admission, detailed anamnestic and laboratory data were obtained, expert ultrasound scan was performed, and power Doppler index （PDI）, risk of malignancy index （RMI） and body mass index （BMI） were calculated for all patients. Obtained data were related to histopathological findings, and statistically analyzed. Results： The study included 689 women （112 malignant, 544 benignant, and 33 borderline tumors）. Malignant and borderline tumors were more frequent in postmenopausal women （P=0.000）. Women who had benignant tumors had the lowest BMI （P=0.000）. There were significant （P〈0.05） differences among tumor types regarding erythrocyte sedimentation rate, CA125 and carcinoembryonic antigen （CEA） levels. Among ultrasound findings, larger tumor diameter and ascites were more frequent in malignant tumors （P=0.000）. Women with malignant tumors had highest values of RMI and PDI （P=0.000）. Conclusions： Anamnestic data, ultrasound parameters and laboratory analyses were all found to be good discriminating factors among malignant, benignant and borderline tumors.
