Elevated ZC3H15 increases HCC growth and predicts poor survival after surgical resection.

ABSTRACT: Zinc finger CCCH-type containing 15 (ZC3H15), also known as DRG family regulatory protein 1 (DFRP1), is a highly conserved eukaryotic protein that associates with active translation machinery. The aim of our study was to explore the clinical relevance and intrinsic functions of ZC3H15 in hepatocellular carcinoma (HCC). We constructed a cohort with 261 tumor and matched normal tissues from HCC patients. ZC3H15 protein and mRNA levels were determined using immunohistochemistry, western blot analysis, and quantitative polymerase chain reaction. ZC3H15 was highly expressed in the majority of HCC cases, and high ZC3H15 levels were significantly associated with high serum a-fetoprotein (AFP) levels (>20 ng/mL) and vascular invasion. Kaplan-Meier and Cox regression data indicated that elevated ZC3H15 was an independent predictor for HCC-specific disease-free survival (hazards ratio [HR], 1.789; 95% confidence interval [95% CI], 1.298-2.466 [P=0.0004]) and overall survival (HR, 1.613; 95% CI, 1.120-2.322 [P=0.0101]). Interaction of ZC3H15 with TRAF2 increased activation of NF?B signaling. These results suggest ZC3H15 is an independent prognostic marker in HCC patients that is clinicopathologically associated with tumor invasion and serum AFP levels.

Project description:BackgroundReports indicate that black patients have lower survival after the diagnosis of a poor prognosis cancer, compared with white patients. We explored the extent to which this disparity is attributable to the underuse of surgery.Study designUsing the Surveillance, Epidemiology, and End Results program and Medicare database, we identified 57,364 patients, ages 65 years and older, with a new diagnosis of nonmetastatic liver, lung, pancreatic, and esophageal cancer, from 2000 to 2005. We evaluated racial differences in resection rates after adjustment for patient, tumor, and hospital characteristics using hierarchical logistic regression. Cox proportional hazards regression was used to assess racial differences in survival after adjusting for patient, tumor, and hospital characteristics, and receipt of surgery.ResultsCompared with white patients, black patients were less likely to undergo surgery for liver (adjusted odds ratio [aOR] = 0.49; 95% CI, 0.29-0.83), lung (aOR = 0.62; 95% CI, 0.56-0.69), pancreas (aOR = 0.53; 95% CI, 0.41-0.70), and esophagus cancers (aOR = 0.64; 95% CI, 0.42-0.99). Hospitals varied in their surgery rates among patients with potentially resectable disease. However, resection rates were consistently lower for black patients, regardless of the resection rate of the treating hospital. Although there were no racial differences in overall survival with liver and esophageal cancer, black patients experienced poorer survival for lung (adjusted hazard ratio = 1.05; 95% CI, 1.00-1.10) and pancreas cancer (adjusted hazard ratio = 1.15; 95% CI, 1.03-1.30). In both instances, there were no residual racial disparities in overall survival after adjusting for use of surgery.ConclusionsBlack patients are less likely to undergo surgery after diagnosis of a poor prognosis cancer. Our findings suggest that surgery is an important predictor of overall mortality, and that efforts to reduce racial disparities will require stakeholders to gain a better understanding of why elderly black patients are less likely to get to the operating room.
