05) and it was not significantly different from that of the CE images. The detection rate of pink or orange color in AF

images was significantly higher for protruded intestinal-type EGCs than gastric adenomas (P = 0.005), depressed intestinal-type EGCs (P < 0.001), and diffuse-type EGCs (P = 0.027). Conclusions:  Autofluorescence videoendoscopy using the SAFE-3000 system for gastric neoplasias might be useful for diagnosing depressed intestinal-type early gastric cancers. The detection of orange or pink color in AF images may be efficacious in discriminating protruded intestinal-type early gastric cancers from gastric adenomas. "
“Knowing the http://www.selleckchem.com/products/DAPT-GSI-IX.html spontaneous outcome of hepatocellular carcinoma (HCC) is

important for designing randomized controlled trials (RCTs) of new therapeutic approaches; however, survival of patients in the absence of treatment is highly variable, and prognostic factors influencing outcomes are incompletely defined. The aims of this meta-analysis were to estimate the 1-year and 2-year survival rates of untreated HCC patients enrolled in RCTs of palliative treatments, and to identify prognostic factors. RCTs evaluating therapies for HCC with placebo or no-treatment arms were identified on MEDLINE through April 2009. Data were combined in a random effect model. Primary outcomes were 1-year and 2-year survival. Thirty studies met the inclusion criteria. The pooled estimates of the survival rates were 17.5% at 1 year (95% confidence interval [95%CI], PLX3397 datasheet 11%-27%; range, 0%-75%) and 7.3% at 2 years (95%CI, 3.9%-13%; range, 0%-50%). Heterogeneity among studies was highly significant (P < 0.0001) both for 1-year and 2-year survival, and persisted when RCTs were stratified according to all patient

and study features. Through meta-regression, impaired performance status, Child-Pugh B-C class, and presence of portal vein thrombosis were GNAT2 all independently associated with shorter survival. Ascites was strongly linked to a worse outcome in intermediate/advanced Barcelona Clinic Liver Cancer stages. Conclusion: This meta-analysis confirms the heterogeneity of behavior of untreated HCC and provides a sound basis for stratifying patients with HCC according to expected survival in future trials of new anti-cancer agents. (HEPATOLOGY 2010.) The extensive application of surveillance programs for early detection of small (<5 cm) hepatocellular carcinoma (HCC) has increased the number of tumors detected within the Milan criteria1 at Barcelona Clinic Liver Cancer (BCLC) stages 0 or A (very early or early),2 and potentially responsive to curative treatments, such as liver transplantation and percutaneous or surgical ablation.3, 4 Nonetheless, most patients with HCC (approximately 70%) are diagnosed at BCLC B (intermediate) and C (advanced) stages (approximately 50%) or BCLC D (end stage, approximately 20%).
