The rise in incidence of hepatocellular carcinoma (HCC) in the United States has been well documented. The purpose of this analysis was to examine temporal trends in HCC incidence, mortality, and survival within the U.S. population. The Surveillance, Epidemiology, and End Results data were used to examine incidence and incidence-based (IB) mortality in HCC from 1973 to 2011. Secular trends in age-adjusted incidence and IB mortality by sex and cancer stage were characterized using the Joinpoint Regression program. In 1973, HCC incidence was 1.51 cases per 100,000, whereas in 2011, HCC incidence was 6.20 cases per 100,000. Although HCC incidence continues to increase, a slowing of the rate of increase occurs around 2006. In a sensitivity analysis, there was no significant increase in incidence and IB mortality from 2009 to 2011. There was a significant increase in overall median survival from the 1970s to 2000s (2 vs. 8 months; P < 0.001). On multivariable Cox's regression analysis, age, sex, race, tumor grade, stage at diagnosis, lymph/vascular invasion, number of primary tumors, tumor size, and liver transplant were independently associated with mortality. Conclusion Our results indicate a deceleration in the incidence of HCC around 2006. Since 2009 and for the first time in four decades, there is no increase in IB mortality and incidence rates for HCC in the U.S. population. The nonsignificant increase in incidence and IB mortality in recent years suggest that the peak of the HCC epidemic may be near. A significant survival improvement in HCC was also noted from 1973 to 2010, which seems to be driven by earlier detection of HCC at a curative stage and greater utilization of curative modalities (especially transplant).

Background Evaluation of indeterminate biliary strictures typically involves collection and analysis of tissue or cells. Brush cytology and intraductal biopsies that are routinely performed during ERCP to assess malignant-appearing biliary strictures are limited by relatively low sensitivity. Objective To study the comparative effectiveness of brushings for cytology and intraductal biopsies in the etiology of biliary strictures. Design Meta-analysis. Setting Referral center. Patients PUBMED and Embase databases were reviewed for studies published to April 2014 where diagnostic correlation of histology was available. Intervention Database and review of study findings. Main Outcome Measurements Sensitivity and specificity. Results The pooled sensitivity and specificity of brushings for the diagnosis of malignant biliary strictures was 45% (95% confidence interval [CI], 40%–50%) and 99% (95% CI, 98%–100%), respectively. The pooled diagnostic odds ratio to detect malignant biliary strictures was 33.43 (95% CI, 14.29–78.24). For intraductal biopsies, the pooled sensitivity and specificity were 48.1% (95% CI, 42.8%–53.4%) and 99.2% (95% CI, 97.6%–99.8%), respectively. The pooled diagnostic odds ratio to detect malignant biliary strictures was 43.18 (95% CI, 19.39–95.83). A combination of both modalities only modestly increased the sensitivity (59.4%; 95% CI, 53.7%–64.8%) with a specificity of 100% (95% CI, 98.8%–100.0%). The Begg-Mazumdar and Egger tests indicated a low potential for publication bias. Limitations Inclusion of low-quality studies. Conclusion Our study suggests that both brushings and biopsy are comparable and have limited sensitivity for the diagnosis of malignant biliary strictures. A combination of both only modestly increases the sensitivity.

Background The rise in incidence of esophageal cancer (EC) in the United States (U.S.) over the last four decades has been well documented; however, data on trends in long-term survival and impact on modern therapies associated with survival is lacking. Methods The Surveillance, Epidemiology, and End Results (SEER) database was queried to identify patients with confirmed EC. Cox proportional hazard regression was used to determine independent mortality factors. Results Of 93,167 patients diagnosed with EC between 1973 and 2009, 49% had a histologic diagnosis of esophageal adenocarcinoma (EAC). There was an increase (almost double) in the proportion of patients with adenocarcinoma from the 1970's to 2000's (n = 2,350; 35% to n = 32,212; 61%, p<0.001). Surgery was performed for localized disease in a majority of EC regardless of type (n = 46,683; 89%). Use of surgical treatment increased significantly over the study period (49% to 64%, p<0.001). There was also an increase in overall median survival (6 months versus 10 months, p<0.001) and 5-year survival rate (9% to 22%, p<0.001). Median survival increased consistently for EAC and squamous cell carcinoma (SCC) until the 1990's. After this period, median survival of EAC continued to increase more rapidly while SCC remained relatively stable. Conclusion A significant survival improvement in esophageal cancer was seen from 1973 to 2009, largely due to earlier detection at a curative stage and greater utilization of treatment modalities (especially surgery). Despite the rising prevalence, patients with EAC have better long-term survival outcomes than those SCC.

Background and Aims Evaluation of indeterminate biliary strictures by brush cytology and intraductal biopsies is limited by low sensitivity. The utility of SpyGlass peroral cholangioscopy for diagnosis of malignant biliary strictures and cholangiocarcinoma (CCA), in particular, remains unclear. Our aim was to study the utility of SpyGlass peroral cholangioscopy and targeted biopsy for diagnosis of malignant biliary strictures and CCA. Methods In this systematic review, PubMed and Embase databases were reviewed for studies published to October 2014. The main outcomes of interest were sensitivity, specificity, and diagnostic odds ratio (DOR) of SpyGlass cholangioscopy in the diagnosis of malignant biliary strictures. Results The search yielded 10 studies involving 456 patients. The pooled sensitivity and specificity of cholangioscopy-guided biopsies in the diagnosis of malignant biliary strictures was 60.1% (95% confidence interval [CI], 54.9%-65.2%) and 98.0% (95% CI, 96.0%-99.0%), respectively. The pooled DOR to detect malignant biliary strictures was 66.4 (95% CI, 32.1-137.5). Four studies included patients who had previous negative imaging and brushings and/or intraductal biopsies. Among these 4 studies, the pooled sensitivity and specificity for diagnosis of malignant biliary strictures was 74.7% (95% CI, 63.3%-84.0%) and 93.3% (95% CI, 85.1%-97.8%), respectively. The pooled DOR was 46.0 (95% CI, 15.4-138.1). Only 1 study directly compared the yield of SpyBite biopsies with standard brushings and biopsies. SpyBite biopsies had a sensitivity of 76.5% compared with brushings (5.8%) and biopsies (29.4%). Six studies specifically reported the role of cholangioscopy with targeted biopsies in the diagnosis of CCA. The pooled sensitivity and specificity to detect CCA was 66.2% (95% CI, 59.7%-72.3%) and 97.0% (95% CI, 94.0%-99.0%), respectively. The pooled DOR to detect CCA was 79.7 (95% CI, 32.7-194.7). Conclusions Our study suggests that SpyGlass cholangioscopy with SpyBite biopsies has moderate sensitivity for the diagnosis of malignant biliary strictures.

Clinical data were obtained from the Corporate Data Warehouse, a centralized VA administrative and clinical data repository that contains patient demographics, International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) or Tenth Revision (ICD-10) diagnosis codes, Current Procedural Terminology (CPT) codes, laboratory WHAT YOU NEED TO KNOW BACKGROUND AND CONTEXT Multiple studies suggest that statins reduce the risks of liver cancer, infections and death in patients with cirrhosis but have incompletely controlled for critical confounding. NEW FINDINGS Adjusting for hyperlipidemia and confounding factors predicting statin use, with comprehensive propensity matching using time-updated covariates, statins were associated with an 8.0-8.7% annual reduction of mortality in patients with cirrhosis. LIMITATIONS Unmeasured residual confounding cannot be excluded. The study included older, mostly male U.S. Veterans who may not completely represent the general U.S. population. IMPACT This study supports and refines understanding of the association of statin therapy with reduced risks of liver cancer, decompensation and death in patients with cirrhosis.
