Objective: To improve the diagnosis of primary gallbladder carcinoma (GBC) with/without hepatic metastases by analyzing our experience of different GBC treatment in our patients. Methods: A retrospective study was carried out to analyze the clinical data of the 139 patients with GBC who underwent hepatic resection in our unit from January 2003 to December 2007. Patients were divided into two groups according to whether they demonstrated hepatic invasion. Tumor presentation, surgical modes, and prognosis of each patient were retrospectively reviewed. Kaplan-Meier curves and log-rank tests were employed to compare the survival rates of those patients undergoing different surgical procedures. Results: Of the 139 patients, 46 were men and 93 were women with the male to female ratio of 1:2.0. Their ages were ranged from 35 to 86 years with a mean age of $62.8{\pm}10.4$ years. There were 73 patients complicated with hepatic invasion (group A), and no hepatic invasion occurred in the other 66 patients (group B). Compared with the group B, the patients with hepatic invasion suffered lower differentiation of tumor (p=0.000), more advanced Nevin staging (p=0.008) and poorer prognosis (p=0.013). Radical resection were more frequently performed in group B (75.76%) than in group A (45.20%) with better outcomes (p=0.000). Conclusion: GBC patients complicated with hepatic invasion had poorer prognosis than those without invasion in long-term follow-ups. Radical resection might result in a satisfied prognosis in patients without hepatic invasion, but appears less favorable than palliative resection in those who were complicated with hepatic invasion.

Novel CoFe2O4/MIL-100(Fe) (CFO/MIL-100(Fe)) core/shell nanofibers were prepared by successive ionic layeradsorption and reaction (SILAR) assembly of MIL-100(Fe) on electrospun CoFe2O4 nanofibers. The MIL-100(Fe) shellswere constructed on the dispersed CoFe2O4 fiber surface with high uniformity, homogeneous thickness and high stability. Due to the inherent porosity of MIL-100(Fe), a higher specific surface area of 225.77 m2/g is achieved for the CFO/MIL-100(Fe)-10 sample. The formed CFO/MIL-100(Fe) catalysts exhibit high catalytic activity towards degradation of rhodamineB (RhB) under visible light irradiation. The photocatalytic activity remains above 77 % within 60 min illumination after fourcycles. Due to the simple synthetic method, highly uniform structure, strong magnetic recoverable, as well as goodphotocatalytic performance, the obtained CFO/MIL-100(Fe) core/shell nanofibers could be promising photocatalysts forpractical application.

Background: The hepatocellular carcinoma is very common in China. Our aim in this report was to investigate clinical and pathological factors based on the current decade data that could influence prognosis of HCC patients after hepatectomy. Methods: Between 2002 and 2009, all patients undergoing hepatectomy for HCC were followed up and reviewed retrospectively. Prognostic factors were studied by univariate and multivariate analysis, with Kaplan-Meier and Cox multivariate survival analyses. Results: Complete clinicopathologic and follow-up data were available for 114 patients. The estimated cumulative survival rates at 1, 3, and 5 yr were 84.6%, 60.2% and 51.8%, respectively. On univariate analysis, key prognostic factors were AFP level, GGT level, tumor size, number of tumors, portal vein invasion, liver cirrhosis status and TNM stage. In the multivariate analysis, tumor size, GGT level, liver cirrhosis status and portal vein invasion were significantly associated with patients' prognosis. Conclusion: Through follow-up of a relatively large cohort of Chinese patients, tumor size, GGT level, liver cirrhosis status, portal vein invasion were revealed as important factors for long-term survival after hepatectomy. Early diagnosis for tumor and the improvement of liver function before surgery are important ways to improve the prognosis.

Serum alpha-fetoprotein (AFP) is a significant marker for clinical diagnosis and prognosis evaluation in hepatocellular carcinoma (HCC) patients. However, some proportion of liver cancer patients are AFP-negative (AFP ${\leq}$20ng/ml). In order to study the differences between clinicopathological factors and prognosis of alpha-fetoprotein negative and positive patients, a total of 114 cases (41 AFP-negative and 73 AFP-positive) were selected for our research. By systematically statistical analysis, the results demonstrated that compared with AFP-negative patients, AFP-positive examples were more likely to feature cirrhosis nodules, non-complete neoplasm capsules, and a poor Edmondson-steiner grade. Furthermore, AFP-negative patients demonstrated a favorable long-term prognosis. By univariate analysis and multivariate analysis with Cox's proportional hazards model, multiple tumors were found to be independent risk factors for worse survival of AFP negative patients; however, less tumor-free margins, multiple tumors and Edmondson-steiner grades III/IV, proved to be independent risk factors leading to a poor prognosis of AFP positive cases. Finally, we can infer that high levels of AFP signify a highly malignant tumor and unfavorable prognosis.
Gallbladder Cancer: a Subtype of Biliary Tract Cancer Which is a Current Challenge in China

Biliary tract cancers, broadly described as malignancies that arise from the biliary tract epithelia, are usually divided into two major clinical phenotypes: cholangiocarcinoma and gallbladder cancer, differing in etiopathogenesis, risk factors, and perhaps molecular and genetic signatures. Atypical symptoms and lack of tumor biomarkers make it difficult to diagnose in early stages. At the time of presentation, few patients are candidates for potentially curative surgical resection. We here assessed and compared features of a total of 150 cases divided into extra- and intrahepatic cholangiocarcinomas and gallbladder cancers (GBC). Althought there were no significant differences in serum tumour marker levels, GBC patients had the poorest prognosis. Furthermore, gallbladder cancer respond poorly to chemotherapy or radiation therapy and approximately half of untreated patients died within 10 months. Therefore, treatment for patients with gallbladder cancer is still in challenge. Outcomes and survival of these patients had improved little over the past three decades - a period in which new successful treatments have greatly contributed to the prolonged patient survival for many other cancers.

Background: There have been no large-scale population-based studies to estimate the subsequent risk of primary liver cancer (PLC) among patients with pyogenic liver abscess (PLA). This study aimed to provide relevant data. Materials and Methods: The Taiwan Longitudinal Health Insurance Database for the years 2000 and 2005 was used. The PLA group were adult inpatients who were newly diagnosed with PLA from 2000 to 2008. The control group was randomly selected and matched with the PLA group in terms of age, sex, and date in which medical treatment was sought other than for PLA. Results: There were 1,987 patients each in the PLA and control groups. In total, 56 had PLC, 48 (2.4%, 601.5 per 100,000 person-years) from the PLA group, and 8 from the control group. After adjusting for potential covariates, the hazard ratio of PLC for the PLA group was 3.4 times that of the control group (95% confidence interval = 1.6-7.3, p <0.001). The PLC risk for the PLA group was significantly higher within the first year after PLA diagnosis (hazard ratio: 35.4) as compared with the control group and became insignificant (hazard ratio: 2.0, 95% confidence interval = 0.8-4.9) more than one year after PLA diagnosis. Conclusions: Patients with PLA have a higher rate of PLC than matched controls, especially within the first year after the diagnosis of PLA, suggesting PLA is a warning sign for PLC.
Potential Therapeutic Targets for the Primary Gallbladder Carcinoma: Estrogen Receptors

Gallbladder carcinoma, the most frequent malignant neoplasm of the biliary tract system, has always been considered to feature late clinical presentation and diagnosis, limited treatment options and an extremely poor prognosis. In recent years, while the incidence of gallbladder cancer has appeared to be on the increase, the available treatment methods have not greatly improved survival of the affected patients. Thus, exploring new therapeutic targets for this devastating disease is an urgent matter at present. Epidemical studies have demonstrated that the incidence of gallbladder carcinoma exhibits a distinct gender bias, affecting females two to three times more than males, pointing to crucial roles of estrogen. It is well known that estrogen acts on target tissues by binding to estrogen receptors (ERs), which are mainly divided into three subtypes, $ER{\alpha}$, $ER{\beta}$ and $ER{\gamma}$. $ER{\alpha}$ and $ER{\beta}$ appear to have overlapping but also unique even opposite biological effects. As important pathogenic mediators, ERs have been considered to relate to several kinds of tumors. In gallbladder carcinoma tissue, ERs have been shown to be positively expressed, and ERs expression levels are associated with differentiation and prognosis of this cancer. Nevertheless, the exact mechanisms of estrogen inducing growth of gallbladder carcinoma remain poorly understood. On the base of the current investigations, we deduce that estrogen participates in promotion of gallbladder carcinoma by influencing the formation of gallstones, stimulating angiogenesis, and promoting abnormal proliferation. Since ERs mediate the carcinogenic actions of estrogen in gallbladder, and therapy targeting ERs may provide new directions for gallbladder carcinoma. Therefore, it should be stressed that ERs are potential therapeutic targets for gallbladder carcinoma.
