Abstract
Background and Objectives: Gallbladder cancer is a rare type of cancer, with aggressive clinical behavior. Limited treatment options provide poor survival prognosis. We aimed to investigate the incidence, mortality trends, and survival of gallbladder and extrahepatic bile duct cancer in Lithuania between 1998 and 2017. Materials and Methods: The study was based on the Lithuanian Cancer Registry database. The study included all cases of cancer of the gallbladder and extrahepatic bile ducts reported to the Registry in the period 1998–2017. Age-specific and age-standardized incidence rates were calculated. In addition, 95% confidence intervals for APC (Annual Percent Change) were calculated. Changes were considered statistically significant if p was <0.05. Relative survival estimates were calculated using period analysis according to the Ederer II method. Results: Age-standardized rates for gallbladder cancer and extrahepatic bile duct cancer among females decreased from 3.91 to 1.93 cases per 100.000 individuals between 1998 and 2017, and from 2.32 to 1.59 cases per 100.000 individuals between 1998 and 2017 among males. The highest incidence rates were found in the 85+ group with 27.5/100,000 individuals in females and 26.8/100,000 individuals in males. The 1-year as well as 5-year relative survival rates of both genders were 34.29% (95% CI 32.12–36.48) and 16.29% (95% CI 14.40–18.27), respectively. Conclusions: Incidence and mortality from gallbladder and extrahepatic bile duct cancer decreased in both sexes in Lithuania. Incidence and mortality rates were higher in females than in males. Relative 1-year and 5-year survival rates showed a steady increase during the study period among males and females.

OLFM4 depletion sensitizes gallbladder cancer cells to cisplatin through the ARL6IP1/caspase-3 axis. Transl Oncol 2022; 16:101331.

Abstract
OLFM4 is involved in development of gallbladder cancer. Depletion of OLFM4 sensitizes gallbladder cancer cells to cisplatin by regulating apoptosis. Low expression of OLFM4 in GBC patients indicates longer survival.
Background Gallbladder cancer (GBC) is a highly lethal malignancy that carries an extremely poor prognosis due to its chemoresistant nature. Cisplatin (CDDP) is a first-line chemotherapeutic for GBC; however, patients experienced no benefit when treated with CDDP alone. The underlying mechanisms of CDDP resistance in GBC remain largely unknown. Methods Agilent mRNA microarray analysis was performed between paired GBC and paracarcinoma to explore differentially expressed genes that might underlie drug resistance. Gene Set Enrichment Analysis (GSEA) was employed to identify key genes mediating CDDP resistance in GBC, and immunohistochemistry was performed to validate protein expression and test correlations with clinicopathological features. In vitro and in vivo functional assays were performed to investigate the proteins’ roles in CDDP resistance. Results Olfactomedin 4 (OLFM4) was differentially expressed between GBC and paracarcinoma and had the highest rank metric score in the GSEA. OLFM4 expression was increasingly upregulated from chronic cholecystitis to GBC in clinical tissue samples, and OLFM4 depletion decreased GBC cell proliferation and invasion. Interestingly, downregulation of OLFM4 reduced ARL6IP1 (antiapoptotic factor) expression and sensitized GBC cells to CDDP both in vitro and in vivo. The evidence indicated that CDDP could significantly increase Bax and Bad expression and activate caspase-3 cascade in OLFM4-depleted GBC cells through ARL6IP1. Clinically, lower OLFM4 expression was associated with good prognosis of GBC patients. Conclusions Our results suggest that OLFM4 is an essential gene that contributes to GBC chemoresistance and could serve as a prognostic biomarker for GBC. Importantly, OLFM4 could be a potential chemotherapeutic target.

Inbreeding, native American ancestry and child mortality: Linking human selection and paediatric medicine. Hum Mol Genet 2021; 31:975-984.

Abstract
The children of related parents show increased risk of early mortality. The Native American genome typically exhibits long stretches of homozygosity, and Latin Americans are highly heterogeneous regarding the individual burden of homozygosity, the proportion, and the type of Native American ancestry. We analysed nationwide mortality and genome-wide genotype data from admixed Chileans to investigate the relationship between common causes of child mortality, homozygosity and Native American ancestry. Results from two-stage linear-Poisson regression revealed a strong association between the sum length of runs of homozygosity (SROH) above 1.5 Megabases (Mb) in each genome and mortality due to intracranial non-traumatic haemorrhage of foetus and new-born (5% increased risk of death per Mb in SROH, P = 1 × 10-3) and disorders related to short gestation and low birth weight (P = 3 × 10-4). The major indigenous populations in Chile are Aymara-Quechua in the north of the country, and the Mapuche-Huilliche in the south. The individual proportion of Aymara-Quechua ancestry was associated with an increased risk of death due to anencephaly and similar malformations (P = 4 × 10-5), and the risk of death due to Edwards and Patau trisomy syndromes decreased 4% per 1% Aymara-Quechua ancestry proportion (P = 4 × 10-4) and 5% per 1% Mapuche-Huilliche ancestry proportion (P = 2 × 10-3). The present results suggest that short gestation, low birth weight and intracranial non-traumatic haemorrhage mediate the negative effect of inbreeding on human selection. Independent validation of the identified associations between common causes of child death, homozygosity and fine-scale ancestry proportions may inform paediatric medicine.

Abstract
PURPOSE There are only a few reports on the treatment-based survival of gallbladder cancer (GBC). The primary objective of this study was to examine the change in treatment modality and the related trends in the survival of GBC. METHODS This study includes all cases of primary GBC diagnosed in the province of Ontario, Canada, from January 2007 to December 2015 with known disease stage. Treatment modalities were classified as no treatment, radiation or chemotherapy, and surgical resection. We examined the association between surgical resection and demographics and tumor characteristics and estimated the trends in survival based on treatment modality. RESULTS In total, 564 patients with GBC were identified, of which 374 (66.3%) were female. Although there were no significant trends in treatment modalities over the study period (p = 0.276), survival rates improved for all treatment modalities over time. There was a 35% increase in 5-year survival for the surgical resection group from 2007 to 2015. For patients with stage I-II disease, the 5-year survival rate increased 40% over time. The highest 5-year survival was observed for the surgical resection group in patients with stage I-II disease (0.533 (95% CI, 0.514-0.552)) while the average 5-year survival rate for all patients over the study period was 0.247 (95% CI, 0.228-0.266). CONCLUSIONS Most cases of GBC continue to be diagnosed in the late stage. Five-year survival for the surgical resection group has markedly improved over time, specifically for patients with stage I-II disease which increased from 30% in 2007 to 70% in 2015.

Abstract
Background
Incidental gallbladder cancer is relatively rare, with an incidence ranging between 0.19 and 5.5% of all the cholecystectomies for benign disease, and carries a poor prognosis. Currently, in the literature, there appears to be some controversy about whether all gallbladder specimens should be sent for routine histopathology. The aim of this study was to investigate the need for either routine or selective histopathological evaluation of all gallbladder specimens following cholecystectomy in our institution.
Methods
The records of all patients who underwent a cholecystectomy (laparoscopic and open) for gallstone disease over a 5-year period (between January 2011 and January 2016) were reviewed retrospectively in a single university teaching hospital. Patients with radiological evidence of gallbladder cancer preoperatively were excluded. The notes of patients with incidental gallbladder cancer were reviewed and data were collected for clinical presentation and preoperative investigations including blood tests and radiological imaging.
Results
A total of 1,473 specimens were sent for histopathological evaluation, with two patients being diagnosed with an incidental gallbladder cancer (papillary adenocarcinoma in situ and moderately differentiated invasive adenocarcinoma [stage IIIa]). The incidence rate was 0.14%. All patients with incidental gallbladder cancer had macroscopically abnormal specimens.
Conclusion
Both patients in our study who were diagnosed with incidental gallbladder cancer had macroscopic abnormalities. A selective rather than routine approach to histological evaluation of gallbladder specimens especially in those with macroscopic abnormalities should be employed. This will reduce the burden on the pathology department with potential cost savings.

Abstract
PURPOSE To describe and interpret secular time trends in gallbladder cancer (GBC) incidence, mortality, and diagnostic approach using 37 years of cancer registry data in urban Shanghai. METHODS Data on registration of GBC in urban Shanghai during 1973 and 2009 were collected by the Shanghai Cancer Registry. To describe time trends and to identify specific time points when significant changes occurred, we used joinpoint regression analysis. RESULTS The age-standardized rates (ASRs) of incidence increased from 1.1/100,000 (1973-1975) to 2.9/100,000 (2006-2009) in men and from 1.7/100,000 (1973-1975) to 3.9/100,000 (2006-2009) in women. ASRs of incidence increased significantly with estimated annual percent changes (EAPCs) of 2.8% in men and 2.5% in women. The mortality trends increased significantly, with EAPCs of 2.8% in men and 2.5% in women. The increasing incidence and mortality rates were primarily observed in men ⩾60 years of age and in women ⩾70 years of age. Notable downward trends in incidence and mortality were identified among women age 60-69 years over the last decade. The percentage of GBC diagnosed by pathology increased steadily over the years while the percentage of GBC diagnosed by imaging, surgery, and biochemistry sharply increased from 1987 onwards. CONCLUSIONS Thirty-seven years of cancer registry data document a tremendous increase in incidence/mortality and a slight decline in incidence/mortality over the last decades for GBC, especially among women, in Shanghai. The development of diagnostic approaches and aging population may play important roles.

Abstract
Uncoupling protein 2 (UCP2) is a mitochondrial anion carrier which plays a key role in energy homeostasis. UCP2 is deregulated in several human cancers and has been suggested to regulate cancer metabolism. However, the role of UCP2 in gallbladder cancer has not been defined. Using clinical samples, we found highly expressed UCP2 in gallbladder cancer tissues, and higher expression levels of UCP2 correlated with worse clinical characteristics. To study whether UCP2 promotes gallbladder cancer growth, UCP2 stable knockdown cells were generated, and cell proliferation was suppressed in these knockdown cells. Further studies demonstrated that glycolysis was inhibited and IKKβ, as well as the downstream signaling molecules NF-κB/FAK/β-catenin, were downregulated in UCP2 knockdown cells. More importantly, gallbladder cancer cells became sensitive to gemcitabine treatments when UCP2 was inhibited. UCP2 knockdown suppressed the activation of the NF-κB/β-catenin axis and promoted the increases in mitochondrial ROS in gallbladder cancer cells exposed to gemcitabine treatments. The UCP2 inhibitor genipin suppressed xenograft tumor growth and sensitized grafted tumors to gemcitabine treatments. These results suggest targeting UCP2 as a novel therapeutic strategy for the treatment of gallbladder cancer.

Abstract
Glutathione-S-transferase T1 (GSTT1) and glutathione-S-transferase M1 (GSTM1) genes are associated with increase susceptibility to developing different types of cancers. The aim of present study was to investigate the role of genetic variants of GSTM1 and GSTT1 in gallbladder cancer (GBC) and cholelithiasis in Kashmir valley. Genotyping was done by multiplex polymerase chain reaction in 100 GBC, 100 cholelithiasis, and 150 controls adjusted by age and sex. We also performed a meta-analysis of published studies on GSTM1 and GSTT1 to evaluate the association between the GSTM1 and GSTT1 polymorphisms and GBC. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using random- or fixed-effects model. In the present study, no association was observed between GSTM1 null and GSTT1 null genotypes and GBC and cholelithiasis. Meta-analysis results showed that GSTM1 null genotype was associated with GBC risk (P = 0.042). Subgroup analysis by ethnicity showed that GSTM1 null (P = 0.024) and GSTT1 null genotype (P = 0.037) were significantly associated with risk of GBC in Asians. This is the first study to investigate the role of genetic variants of GSTM1 and GSTT1 in GBC in Kashmir valley and cholelithiasis in the world.

Abstract
BACKGROUND Equipoise exists regarding the benefit of adjuvant therapy (AT) in patients with gallbladder cancer (GBC). The aim of this study was to critically review the available evidence for the effectiveness of AT in patients with GBC following surgery with curative intent. METHODS A systematic review was performed. Relevant studies were identified from Trip Database, BIREME-BVS, SciELO, Cochrane Central Register, WoS, MEDLINE, EMBASE and SCOPUS. Adjuvant therapies considered included chemotherapy, chemoradiotherapy, and radiotherapy. The primary outcome was overall survival (OS). Subgorup analysis of patients with positive lymph node disease (PLND), positive surgical margin (PSM), or advanced stage (AS) were performed. RESULTS 748 related articles were identified; 27 met the selection criteria (3 systematic reviews and 24 observational studies). Evidence provided was moderate, poor and very poor for chemotherapy, chemoradiotherapy, and radiotherapy. Existing evidence is not robust, but suggests certain benefits with AT in improving OS, especially in patients with PLND, PSM and AS. CONCLUSION Results do not provide strong evidence that AT is effective in patients who undergo resection for GBC. Subgroups of PLND and PSM may have a survival advantage. Future studies with appropriate internal validity and adequate number of patients are required to better answer this question.

Abstract
INTRODUCTION Gallbladder cancer (GBC) is a rare tumor in developed countries. Chile has one of the highest incidences worldwide. For patients affected by resectable T1b or more advanced GBC, radical cholecystectomy (RC) is considered the standard therapy. Our aim is to describe the surgical technique and clinical-pathological results of patients undergoing totally laparoscopic radical resection of GBC. METHODS Patients undergo laparoscopic radical resection for primary and incidental GBC, between the years 2009 and 2016 in two centers from Chile. Patients in whom suspected bile duct invasion, frozen biopsy did not confirm cancer and para-aortic lymph node sampling was positive were excluded. RESULTS Eighteen patients were operated, 77.8% were female with median age of 60.5 year, and 16 patients had previous cholecystectomy with incidental cancer finding. The median operative time was 490 min (400-550). No conversion to open surgery occurred. All patients achieved a R0 resection. Postoperative complications occurred in 2 patients (11.1%), and there was not mortality. After a median follow-up of 59 months, the 5-year survival was 80.7%. CONCLUSION This study shows the technical feasibility of the totally laparoscopic approach for radical resection of GBC with the same principles of classical open surgery. It appears that long-term oncological findings would also be similar at least in less advanced lesions.

Abstract
Gallbladder cancer is a rare malignancy of the biliary tract with a poor prognosis, frequently presenting at an advanced stage. While rare in the United States overall, gallbladder cancer has an elevated incidence in geographically distinct locations of the globe including Chile, North India, Korea, Japan and the state of New Mexico in the United States. People with Native American ancestry have a much elevated incidence of gallbladder cancer compared to Hispanic and non-Hispanic white populations of New Mexico. Gallbladder cancer is also one of the few bi-gendered cancers with an elevated female incidence compared to men. Similar to other gastrointestinal cancers, gallbladder cancer etiology is likely multi-factorial involving a combination of genomic, immunological, and environmental factors. Understanding the interplay of these unique epidemiological factors is crucial in improving the prevention, early detection, and treatment of this lethal disease. Previous studies have failed to identify a distinct genomic mutational profile in gallbladder cancers, however, work to identify promising clinically actionable targets is this form of cancer is ongoing. Examples include, interest in the HER2/Neu signaling pathway and the recognition that chronic inflammation plays a crucial role in gallbladder cancer pathogenesis. In this review, we provide a comprehensive overview of gallbladder cancer epidemiology, risk factors, pathogenesis, and treatment with a specific focus on the rural and Native American populations of New Mexico. We conclude this review by discussing future research directions with the goal of improving clinical outcomes for patients of this lethal malignancy.

Subtypes of Native American ancestry and leading causes of death: Mapuche ancestry-specific associations with gallbladder cancer risk in Chile. PLoS Genet 2017; 13:e1006756.

Abstract
Latin Americans are highly heterogeneous regarding the type of Native American ancestry. Consideration of specific associations with common diseases may lead to substantial advances in unraveling of disease etiology and disease prevention. Here we investigate possible associations between the type of Native American ancestry and leading causes of death. After an aggregate-data study based on genome-wide genotype data from 1805 admixed Chileans and 639,789 deaths, we validate an identified association with gallbladder cancer relying on individual data from 64 gallbladder cancer patients, with and without a family history, and 170 healthy controls. Native American proportions were markedly underestimated when the two main types of Native American ancestry in Chile, originated from the Mapuche and Aymara indigenous peoples, were combined together. Consideration of the type of Native American ancestry was crucial to identify disease associations. Native American ancestry showed no association with gallbladder cancer mortality (P = 0.26). By contrast, each 1% increase in the Mapuche proportion represented a 3.7% increased mortality risk by gallbladder cancer (95%CI 3.1–4.3%, P = 6×10−27). Individual-data results and extensive sensitivity analyses confirmed the association between Mapuche ancestry and gallbladder cancer. Increasing Mapuche proportions were also associated with an increased mortality due to asthma and, interestingly, with a decreased mortality by diabetes. The mortality due to skin, bladder, larynx, bronchus and lung cancers increased with increasing Aymara proportions. Described methods should be considered in future studies on human population genetics and human health. Complementary individual-based studies are needed to apportion the genetic and non-genetic components of associations identified relying on aggregate-data. A lot of attention has been paid to Latino heterogeneity related to individual proportions of Native American, European and African ancestry. The importance of the type of Native American ancestry for health, however, has hardly been studied. Here we examined genetic data from 2,039 admixed Chileans to investigate possible associations between top causes of death and the two major types of Native American ancestry in Chile. Our findings demonstrate the necessity of suitable surrogates for ancestry estimation which mirror the actual composition of the study population, and the advantage of considering fine-scale Latino heterogeneity for unraveling of disease etiology and personalized healthcare.

Abstract
Cyclooxygenase-2 (COX-2) and extracellular signal-regulated kinase 1/2 (ERK1/2) may serve as potential targets in various types of cancer; however, the roles of these proteins in gallbladder carcinoma (GBC) have not been reported previously. In the present study, the expression levels of COX-2 and phospho (p)-ERK1/2 in GBC were examined and the biological activities of celecoxib and PD184161 (specific inhibitors of COX-2 and p-ERK1/2, respectively) on the proliferation, cell cycle and apoptosis of the GBC-SD and NOZ human GBC cell lines were evaluated by a series of in vitro and in vivo studies. COX-2 and p-ERK1/2 protein expression levels were found to be significantly elevated in GBC tissues as well as in GBC-SD and NOZ cells. Treatments with celecoxib and PD184161 significantly inhibited GBC-SD and NOZ cell growth in a concentration-dependent manner, and their combination produced a synergistic inhibitory effect. In addition, celecoxib and PD184161 significantly inhibited tumor growth in xenograft nude mice. Celecoxib treatment led to G1 arrest via the upregulation of p21 and p27 expression in GBC-SD and NOZ cells, whereas PD184161 did not affect cell cycle distribution. The combination of celecoxib and PD184161 was able to promote cell apoptosis by triggering a collapse of mitochondrial membrane potential and activating caspase-3-mediated apoptosis. In conclusion, COX-2 and p-ERK1/2 protein may serve as potential targets for GBC chemotherapy, and the combination of celecoxib and PD184161 could significantly inhibit GBC cell growth, induce cell G1 arrest and trigger cell apoptosis of GBC cells.

Abstract
Primary gallbladder cancer is an aggressive and uncommon cancer with poor outcomes. Our study examines epidemiology, trend, and survival of gallbladder cancer in the United States from 1973 to 2009. We utilized the Surveillance Epidemiology and End Results database (SEER). Frequency and rate analyses on demographics, stage, and survival were compared among non-Hispanic whites, Hispanics, African American, and Asian/Pacific Islanders. A total of 18,124 cases were reported in SEER from 1973 to 2009 comprising 1.4% of all reported gastrointestinal cancers. Gallbladder cancer was more common in females than males (71 vs. 29%, respectively). The age-adjusted incidence rate was 1.4 per 100,000, significantly higher in females than males (1.7 vs. 1.0). Trend analysis showed that the incidence rate has been decreasing over the last three decades for males. However, among females, the incidence rate had decreased from 1973 to mid-90s but has remained stable since then. Trend analysis for stage at diagnosis showed that the proportion of late-stage cases has been increasing significantly since 2001 after a decreasing pattern since 1973. Survival has improved considerably over time, and survival is better in females than males and in Asian/Pacific Islanders than other racial groups. The highest survival was in patients who received both surgery and radiation. Trend analysis revealed a recent increase of the incidence of late-stage gallbladder cancer. Highest survival was associated with receiving both surgery and radiation.

Abstract
Increasing evidence has revealed a correlation between chronic inflammation and gallbladder cancer (GBC). However, the underlying molecular mechanisms remain to be elucidated. In the present study, secretion of interleukin (IL)-1β was examined in tissues of GBC, chronic cholecystitis and normal gallbladder, as well as in the supernatant of GBC-SD, SGC996 and HIBEpiC cells. The effect of IL-1β on the proliferation and migration of GBC cell lines was also evaluated. In addition, the role of Twist in IL-1β-induced proliferation of GBC cells was also studied. It was observed that the level of IL-1β protein in normal gallbladder tissue was low, while it was significantly increased in GBC and chronic cholecystitis tissues. The level of IL-1β protein and mRNA in GBC-SD and SGC996 cells was markedly higher than those in HIBEpiC cells. Exogenous IL-1β promoted the proliferation of GBC-SD and SGC996 cells in vitro and in vivo, and also promoted migration in vitro. The level of Twist protein was significantly increased following treatment with exogenous IL-1β. In addition, gene silencing of Twist blocked IL-1β-induced proliferation and migration of GBC-SD and SGC996 cells. Taken together, these results indicate that IL-1β promotes proliferation and migration of GBC cells via Twist activation.

Abstract
BACKGROUND Telomeres play an important role in cancer progression. Recently it has been shown that subtelomeric methylation negatively regulates telomere length in various diseases, including cancers. Here, we evaluated the influence of subtelomeric methylation in telomere dysfunction in gallbladder cancer (GBC), and whether this dysfunction is affected by the presence of gallstones. METHODS Relative telomere length and subtelomeric methylation levels were assessed using monochrome multiplex quantitative polymerase chain reaction and bisulfite sequencing, respectively, in different gallbladder tissue types including different grades of GBC, gallstones and adjacent non-tumor. RESULTS We found telomere length to shorten significantly in overall GBC, but specifically in early grade cancer. We also found D4Z4 and DNF92 subtelomeric sequences to be hypermethylated and hypomethylated, respectively, in GBC; however, their methylation levels differed significantly, only in early grade cancer. We could not find any specific correlation between subtelomeric methylation and telomere length in GBC. Interestingly, telomere length and subtelomeric methylation differed significantly in GBC without gallstones but not in GBC with gallstones. CONCLUSIONS This study, thus, suggests that telomere dysfunction and changes in methylation levels may occur earlier in the progression of GBC, while the presence of gallstones may have no influence on telomere length as well as on methylation levels.

Int J Mol Sci 2015; 16:28038-49. [PMID: 26602921 PMCID: PMC4691025 DOI: 10.3390/ijms161226077] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2015] [Revised: 11/12/2015] [Accepted: 11/13/2015] [Indexed: 12/16/2022] Open
Abstract
Gallbladder cancer is the most common and a highly aggressive biliary tract malignancy with a dismal outcome. The pathogenesis of the disease is multifactorial, comprising the combined effect of multiple genetic variations of mild consequence along with numerous dietary and environmental risk factors. Previously, we demonstrated the association of several candidate gene variations with GBC risk. In this study, we aimed to identify the combination of gene variants and their possible interactions contributing towards genetic susceptibility of GBC. Here, we performed Multifactor-Dimensionality Reduction (MDR) and Classification and Regression Tree Analysis (CRT) to investigate the gene–gene interactions and the combined effect of 14 SNPs in nine genes (DR4 (rs20576, rs6557634); FAS (rs2234767); FASL (rs763110); DCC (rs2229080, rs4078288, rs7504990, rs714); PSCA (rs2294008, rs2978974); ADRA2A (rs1801253); ADRB1 (rs1800544); ADRB3 (rs4994); CYP17 (rs2486758)) involved in various signaling pathways. Genotyping was accomplished by PCR-RFLP or Taqman allelic discrimination assays. SPSS software version 16.0 and MDR software version 2.0 were used for all the statistical analysis. Single locus investigation demonstrated significant association of DR4 (rs20576, rs6557634), DCC (rs714, rs2229080, rs4078288) and ADRB3 (rs4994) polymorphisms with GBC risk. MDR analysis revealed ADRB3 (rs4994) to be crucial candidate in GBC susceptibility that may act either alone (p < 0.0001, CVC = 10/10) or in combination with DCC (rs714 and rs2229080, p < 0.0001, CVC = 9/10). Our CRT results are in agreement with the above findings. Further, in-silico results of studied SNPs advocated their role in splicing, transcriptional and/or protein coding regulation. Overall, our result suggested complex interactions amongst the studied SNPs and ADRB3 rs4994 as candidate influencing GBC susceptibility.

Abstract
Background PTEN is a tumor suppressor gene that regulates the PTEN/PI3k/AKT/mTOR pathway, which is frequently altered in human cancers including gallbladder cancer (GBC). To determine the frequency of PTEN expression in GBC and to establish its relation to clinical and morphological parameters and survival in GBC. Methods The immunohistochemical expression of PTEN was studied in 108 GBC. All the cases included areas of non-tumor mucosa adjacent to the tumor. Results The group was comprised of 108 patients, 91 women (84.3 %) and 17 men (15.7 %) with an average age of 65.2 years (SD ± 12.3 years). Thirty-five cases (33 %) were early carcinomas (EC) and the remaining 73 (67 %) were advanced cases (AC). All the internal controls were positive (moderate or intense in 96.3 %). Only in three AC (4.1 %) was there a complete absence of PTEN immunohistochemical expression. There were no significant differences in relation between PTEN expression and tumor infiltration or degree of differentiation. The three patients with PTEN inactivation died before 10 months; however, the other patients with AC had a survival of 53 % at 10 months. Discussion Loss of PTEN expression was observed in 4.1 % of the advanced GBC. All the patients with this alteration died before 10 months. PTEN inactivation could be a rare event, but with a poor prognosis in advanced GBC.

Abstract
PURPOSE OF REVIEW Gallbladder cancer (GBC) should be considered an orphan disease in oncology and represent a unique carcinogenetic model. This review will analyse some of the current aspects of GBC. RECENT FINDINGS Chile has the highest incidence and mortality of GBC in the world. Most patients are diagnosed in advanced stages with few treatment options. During the last two decades, little progress has been made in early diagnosis and treatment. At the molecular level, recent access to next-generation sequencing and other techniques for detecting the mutations of multiple genes have made advances in this area. SUMMARY The use of therapies targeted according to the detection of specific molecular alterations is in the early stages of evaluation and could represent a significant advance in the treatment of a large number of patients from developing countries.

Abstract
BACKGROUND The strong female predominance of biliary tract cancer (BTC) may be related to reproductive factors. We aimed to clarify whether parity or age at first birth influence the risk of BTC. METHODS This was a population-based, case-control study including Swedish female and male cases of cancer of the gallbladder (GBC), extra hepatic bile ducts (EHCC), or the ampulla of Vater (AVC) between 1960 and 2008. For each case, 10 age- and sex-matched controls were randomly selected. Conditional logistic regression was used to calculate odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for potential confounders. RESULTS In total, 1169 cases of GBC, 432 cases of EHCC and 295 cases of AVC were included. Multi- and nulliparous women and men had an increased risk of all tumor locations in the biliary tract compared to uniparous women and men, respectively. Whereas higher age at first birth was associated with a decreased risk of GBC in women, no such association was found in men. There were no clear differences in the risk of EHCC and AVC between women and men. CONCLUSION Sex hormones may play a role in the etiology of GBC. The associations between reproductive factors and EHCC and AVC are similar in women and men, which do not support the sex hormone hypothesis.

Abstract
BACKGROUND Interleukin 6 (IL-6)-mediated signal transducers and activators of transcription 3 (STAT-3) phosphorylation (activation) is aberrantly sustained in cholangiocarcinoma cells resulting in enhanced myeloid cell leukemia 1 (Mcl-1) expression and resistance to apoptosis. FTY720, a new immunosuppressant, derived from ISP-1, has been studied for its putative anti-cancer properties. This study aimed to elucidate the mechanism by which FTY720 mediates antitumor effects in cholangiocarcinoma (CC) cells. METHODS Three CC cell lines were examined, QBC939, TFK-1, and HuCCT1. The therapeutic effects of FTY720 were evaluated in vitro and in vivo. Cell proliferation, apoptosis, cell cycle, invasive potential, and epithelial- mesenchy-mal transition (EMT) were examined. RESULTS FTY720 greatly inhibited CC cells proliferation and EMT in vitro and in vivo, and this effect was associated with dephosphorylation of STAT3tyr705. FTY720 induced apoptosis and G1 phase arrest in CC cells, and inhibited invasion of CC cells. Western blot analysis showed that FTY720 induced cleavage of caspases 3, 8 and 9, and of PARP, in a dose-dependent manner, consistent with a substantial decrease in p-STAT3, Bcl-xL, Bcl-2, survivin, cyclin D1, cyclin E, N-cadherin, vimentin, VEGF and TWIST1. In vivo studies showed that tumor growth and metastasis were significantly suppressed after FTY720 treatment. CONCLUSIONS These results suggest that FTY720 induces a significant decrease in p-STAT3, which inhibits proliferation and EMT of CC cells, and then induces G1 phase arrest and apoptosis. We have characterized a novel immunosuppressant, which shows potential anti-tumor effects on CC via p-STAT3 inhibition. FTY720 merits further investigation and warrants clinical evaluation.

Abstract
Gallbladder cancer (GBC) shows a marked geographical variation in its incidence. Middle-aged and elderly women are more commonly affected. Risk factors for its development include the presence of gallstones, chronic infection and pancreaticobiliary maljunction. Controversy remains in regard to the theory of carcinogenesis from adenomyomatosis, porcelain gallbladder and adenoma of the gallbladder. The surgical strategy and prognosis after surgery for GBC differ strikingly according to T-stage. Discrimination of favorable cases, particularly T2 or T3 lesions, is useful for the selection of surgical strategies for individual patients. Although many candidate factors predicting disease progression, such as depth of subserosal invasion, horizontal tumor spread, tumor budding, dedifferentiation, Ki-67 labeling index, p53 nuclear expression, CD8+ tumor-infiltrating lymphocytes, mitotic counts, Laminin-5-gamma-2 chain, hypoxia-inducible factor-1a, cyclooxygenase-2 and the Hedgehog signaling pathway have been investigated, useful prognostic makers or factors have not been established. As GBC is often discovered incidentally after routine cholecystectomy and accurate preoperative diagnosis is difficult, close mutual cooperation between surgeons and pathologists is essential for developing a rational surgical strategy for GBC.

Abstract
AIM The aim of the study was to evaluate the use of global and gene-specific DNA methylation changes as potential biomarkers for gallbladder cancer (GBC) in a cohort from Chile. MATERIAL & METHODS DNA methylation was analyzed through an ELISA-based technique and quantitative methylation-specific PCR. RESULTS Global DNA Methylation Index (p = 0.02) and promoter methylation of SSBP2 (p = 0.01) and ESR1 (p = 0.05) were significantly different in GBC when compared with cholecystitis. Receiver curve operator analysis revealed promoter methylation of APC, CDKN2A, ESR1, PGP9.5 and SSBP2, together with the Global DNA Methylation Index, had 71% sensitivity, 95% specificity, a 0.97 area under the curve and a positive predictive value of 90%. CONCLUSION Global and gene-specific DNA methylation may be useful biomarkers for GBC clinical assessment.

Abstract
BACKGROUND AND OBJECTIVES Phospholipase C epsilon 1 (PLCE1) plays crucial roles in carcinogenesis and progression of esophageal and gastric cancers. In the present study, we investigated association of GWAS identified rs2274223 A>G and. rs7922612 T>C polymorphism of PLCE1 with susceptibility to gallbladder cancer (GBC). METHODS The study involved genotyping of selected PLCE1 variants in 416 GBC cases and 225 controls. Haplotype analysis was done by SNPStats. In silico analyses were performed using bioinformatic tools. RESULTS PLCE1 rs2274223 [AG] and rs7922612 [CC] genotypes were found to be significantly associated with an increased risk of GBC [OR = 1.9, p = 0.002; OR = 2.0, p = 0.04, respectively]. PLCE1 haplotype [Grs2274223-Crs7922612] also showed significant association with GBC [OR = 1.8, p = 0.04]. The association was significant in females and GBC patients with stones and female GBC patients with gallstones [OR = 2.6, p = 0.01; OR = 3.3, p = 0.007], respectively. However, no significant associations with other risk factors such as tobacco usage and age of onset were found. Functional prediction of rs2274223 A>G suggested change in protein coding and splicing regulation. CONCLUSION The present study found a significant association of PLCE1 rs2274223 and rs7922612 polymorphisms with susceptibility to GBC probably through gallstone-mediated inflammatory pathway.

Abstract
OBJECTIVES To explore gallbladder cancer (GBC), the second leading cause of cancer-related death in women in Chile. METHODS Analysis of macroscopic and microscopic variables, morphometry, and survival in 1,366 patients with GBC. RESULTS Patients comprised 1,138 women and 228 men; diagnoses included 213 (15.6%) cases of mucosal carcinoma, 132 (9.7%) cases of muscular carcinoma, 316 (23.1%) cases of subserosal carcinoma, 382 (28.0%) cases of serosal carcinoma, and 323 (23.6%) cases beyond the serosa. Women older than 55 years with a gallbladder length greater than 9.5 cm had a five-times-greater relative risk of cancer. Those with a gallbladder wall thickness less than 7 mm had a better 5-year survival rate than those with a gallbladder wall thickness greater than 10 mm (P = .0001). Patients who had cholesterolosis of the gallbladder had 9.2 times less probability of having cancer. The infiltration level of the gallbladder wall was the most important independent prognostic factor (P < .001), followed by differentiation and lymphatic involvement (P < .001 and P = .05, respectively). Vascular infiltration had a mortality rate of 100%. CONCLUSIONS Morphologic features are strongly associated with the prognosis of GBC and must be taken into consideration when supplementary treatment is recommended.

Abstract
BACKGROUND Residual disease (RD) at definitive resection of incidental gallbladder cancer (IGBCA) influences outcome, but its clinical relevance with respect to anatomic site is incompletely characterized. STUDY DESIGN Consecutive patients with IGBCA undergoing re-exploration from 1998 to 2009 were identified; those submitted to a complete resection were analyzed. Demographics and tumor- and treatment-related variables were correlated with RD and survival. Cancer-specific survival was stratified by site of RD (local [gallbladder bed]; regional [bile duct, lymph nodes]; distant [discontiguous liver, port site, peritoneal]). RESULTS Of the 135 patients submitted to re-exploration, RD was found in 82 (61%) overall and in 63 (54%) of 116 patients submitted to resection; the most common site was regional (n = 27, 43%). The T stage of the gallbladder specimen was the only independent predictor of RD (T1b = 35.7%, T2 = 48.3%, T3 = 70%, p = 0.015). The presence of RD at any site dramatically reduced median disease-free survival (DFS) (11.2 vs 93.4 months, p < 0.0001) and disease-specific survival (DSS) (25.2 months vs not reached, p < 0.0001) compared with no RD, respectively. Disease-specific survival did not differ according to RD location, with all anatomic sites being equally poor (p = 0.87). Residual disease at any site predicted DFS (hazard ratio [HR] 3.3, 95% CI 1.9 to 5.7, p = 0.0003) and DSS (HR 2.4, 95% CI 1.2 to 4.6, p = 0.01), independent of all other tumor-related variables. CONCLUSIONS Survival in patients with RD at local or regional sites was not significantly different than that seen in stage IV disease, with neither subgroup clearly benefiting from reoperation. Outcomes were poor in all patients with RD, regardless of location.

Abstract
More than half of patients in this study with findings concerning for gallbladder malignancy were found to have benign disease, suggesting that an initial laparoscopic approach may be appropriate in selected patients. Background and Objectives: We examined patients with clinical findings that are concerning for gallbladder malignancy to determine the incidence of pathology-confirmed malignancy and to discover factors that may be used to determine which patients may be initially treated with a laparoscopic approach. Methods: All patients referred to a surgical oncologist with preoperative findings that are concerning for gallbladder malignancy who had not undergone previous surgical resection from 2005 to 2011 were reviewed. Variables collected included demographics, imaging, operative findings, and final pathology. Patients were grouped into 3 categories based on preoperative findings: gallbladder mass, irregular wall thickening, and abnormal intraoperative findings on previous diagnostic laparoscopy. Results: Twenty-nine of 4474 patients evaluated for gallbladder pathology during the study period met the inclusion criteria. Preoperative imaging included computed tomography, ultrasonography, and magnetic resonance imaging. Twelve patients had multiple imaging studies. Eight patients were initially treated with a laparoscopic approach with 3 conversions to an open procedure. Forty-eight percent of patients had pathology-confirmed malignancy. Patients without a discrete mass on imaging were more likely to have benign disease (P = .04). Conclusions: Our results demonstrate that >50% of patients with suspicious preoperative findings had benign pathology, suggesting that the initial laparoscopic approach in selected patients may be appropriate.

Abstract
BACKGROUND Gallbladder cancer (GBC) is a rare malignancy, yet certain groups are at higher risk. Knowledge of predisposing factors may facilitate earlier diagnosis by enabling targeted investigations into otherwise non-specific presenting signs and symptoms. Detecting GBC in its initial stages offers patients their best chance of cure. METHODS PubMed was searched for recent articles (2008-2012) on the topic of risk factors for GBC. Of 1490 initial entries, 32 manuscripts reporting on risk factors for GBC were included in this review. RESULTS New molecular perspectives on cholesterol cycling, hormonal factors and bacterial infection provide fresh insights into the established risk factors of gallstones, female gender and geographic locality. The significance of polyps in predisposing to GBC is probably overstated given the known dysplasia-carcinoma and adenoma-carcinoma sequences active in this disease. Bacteria such as Salmonella species may contribute to regional variations in disease prevalence and might represent powerful targets of therapy to reduce incidences in high-risk areas. Traditional risk factors such as porcelain gallbladder, Mirizzi's syndrome and bile reflux remain important as predisposing factors. CONCLUSIONS Subcentimetre gallbladder polyps rarely become cancerous. Because gallbladder wall thickening is often the first sign of malignancy, all gallbladder imaging should be scrutinized carefully for this feature.

Abstract
PURPOSE To assess the value of FDG-PET/CT in the evaluation of gallbladder carcinomas (GBC). METHODS A prospective cohort of patients with suspicion of or confirmed GBC was studied with FDG-PET/CT. Diagnostic accuracy parameters were calculated in comparison with pathology and/or the clinical course of patients. Clinical impact of PET/CT imaging was estimated. RESULTS Forty-nine patients were enrolled (34 malignant tumors, 15 benign lesions; 37 staging, 12 restaging). Overall diagnostic accuracy was 95.9% for the diagnosis of the primary lesion, 85.7% for lymph node involvement and 95.9% for metastatic disease. Mean SUVmax in malignant gallbladder lesions was 7.92 ± 6.25 Analysis of ROC curves showed a SUVmax cut-off value of 3.62 for malignancy (S: 78.1%; Sp: 88.2%). Diagnostic accuracy in the restaging group reached 100%. FDG-PET/CT changed the management of 22.4% of the population. COMMENTS Diagnosis of malignancy or benignity of suspicious gallbladder lesions is accurately made with FDG PET/CT, allowing a precise staging of GBC due to its ability to identify unsuspected metastatic disease. SUVmax has a complementary role in addition to visual analysis.

Association between glutathione S-transferase M1 null genotype and risk of gallbladder cancer: a meta-analysis. Tumour Biol 2013; 35:501-5.

Abstract
Glutathione S-transferases (GSTs) are a family of enzymes which are involved in the detoxification of potential carcinogens. Glutathione S-transferase M1 (GSTM1) null genotype can impair the enzyme activity of GSTs and is suspected to increase the susceptibility to gallbladder cancer. Previous studies investigating the association between GSTM1 null genotype and risk of gallbladder cancer reported inconsistent findings. To quantify the association between GSTM1 null genotype and risk of gallbladder cancer, we performed a meta-analysis of published studies. We searched PubMed, Embase, and Wanfang databases for all possible studies. We estimated the pooled odds ratio (OR) with its 95% confidence interval (95% CI) to assess the association. Meta-analysis of total included studies showed that GSTM1 null genotype was not associated with gallbladder cancer risk (OR = 1.13, 95% CI 0.88-1.46, P = 0.332). Subgroup analysis by ethnicity showed that there was no association between GSTM1 null genotype and risk of gallbladder cancer in both Caucasians and Asians. However, meta-analysis of studies with adjusted estimations showed that GSTM1 null genotype was associated with increased risk of gallbladder cancer (OR = 1.46, 95% CI 1.02-2.09, P = 0.038). Thus, this meta-analysis shows that GSTM1 null genotype is likely to be associated with risk of gallbladder cancer. More studies with well design and large sample size are needed to further validate the association between GSTM1 null genotype and gallbladder cancer.

Abstract
BACKGROUND AND AIM PSCA is a tissue specific tumor suppressor or oncogene which has been found to be associated with several human tumors including gallbladder cancer. It is considered to be involved in the cell-proliferation inhibition and/or cell-death induction activity. Therefore, we aimed to investigate the role of PSCA gene polymorphisms in gallbladder cancer risk in North Indian population. METHODOLOGY A total of 405 gallbladder cancer patients and 247 healthy controls were included in the case-control study for risk prediction. We examined the association of two functional SNPs, rs2294008 and rs2978974 in PSCA gene by genotyping using Taqman allelic discrimination assays. Statistical analysis was done using SPSS software, version 17. Linkage disequilibrium and haplotype analysis was done with the help of SNPstats software. FDR test was used to correct for multiple comparisons. RESULTS No significant associations of rs2294008 and rs2978974 genetic variants of the PSCA gene were found with GBC risk at allele, genotype or haplotype levels. Stratifying the subjects on the basis of gallstone also did not show any significant result. However, on gender stratification, we found a significant association of Trs2294008-Grs2978974 haplotype with higher risk of GBC in females (FDR Pcorr=0.021, OR=1.6). In contrary, Trs2294008-A rs2978974 haplotype conferred significant lower risk in males (FDR Pcorr=0.013; OR=0.25). CONCLUSIONS These findings suggest that PSCA genetic variants may have a significant effect on GBC susceptibility in a gender specific manner.

Abstract
Gallbladder cancer (GBC) is the most common biliary tract malignancy with an extremely poor prognosis. Epidemiological data have demonstrated that chronic inflammation resulting from infection of gallbladder or gallstones predispose individuals to GBC. Recent studies have begun to elucidate molecular mechanisms underlying the development of GBC in the setting of chronic inflammation. It is possible that persistently local inflammatory reactions may contribute to the development and progression of GBC through inducing genetic alterations, and subsequent promoting survival and proliferation of mutated sells, inhibiting apoptosis, stimulating angiogenesis and metastasis. This article reviews the current understanding of the involvement of chronic inflammation in gallbladder tumorigenesis.

Abstract
BACKGROUND AND AIM GBC is a lethal and multifaceted disease. Deleted in colorectal carcinoma (DCC) is a well known tumor suppressor gene. Recently a small genome-wide association study (GWAS) identified DCC to be significantly associated with gallbladder cancer (GBC) susceptibility in a Japanese population sample. However, the study sample size was small and lacked independent replication. Therefore, the present study was carried out to replicate the association of two GWAS identified DCC SNPs (A>Grs4078288, C>Trs7504990) and two other SNPs (C>Grs2229080 and A>Grs714) previously associated with various cancers. METHODOLOGY The study was accomplished in 406 GBC cases and 260 healthy control samples from North India. Genotyping was carried out by PCR-RFLP and Taqman genotyping assays. Statistical analysis was performed by using SPSS ver16 and functional prediction of these variants was carried out using Bioinformatics tools (FAST-SNP, F-SNP). RESULT We did not observe association with GWAS-identified SNPs of DCC but other SNPs showed significant association. In addition, a DCC haplotype Grs2229080-Ars4078288-Crs7504990-Ars714 conferred high risk of GBC in India. The haplotype associated risk was independent of gallstone, sex or tobacco usages which are well-known modifiers of GBC risk. Further analysis suggested DCC A>Grs714 as a major risk conferring SNP in the Indian population. CONCLUSION This study re-affirms the role of plausible tumor suppressor DCC variants, in gallbladder carcinogenesis and the risk haplotype may be explored as a useful marker for GBC susceptibility.

Abstract
Schwannoma is a tumor derived from Schwann cells which usually arises in the upper extremities, trunk, head and neck, retroperitoneum, mediastinum, pelvis, and peritoneum. However, it can arise in the gastrointestinal tract, including biliary tract. We present a 24-year-old male patient with obstructive jaundice, whose investigation with computed tomography abdomen showed focal wall thickening in the common hepatic duct, difficult to differentiate with hilar adenocarcinoma. He was diagnosed intraoperatively schwannoma of common bile duct and treated with local resection. The patient recovered well without signs of recurrence of the lesion after 12 mo. We also reviewed the common bile duct schwannoma related in the literature and evaluated the difficulty in pre and intraoperative differential diagnosis with adenocarcinoma hilar. Resection is the treatment of choice for such cases and the tumor did not recur in any of the resected cases.

Abstract
BACKGROUND Carcinoma of gallbladder (GBC) is an aggressive malignancy. The higher incidence of gallbladder cancer in women has been partly attributed to hormonal factors. Therefore the present study was designed to explore the role of genetic variants in estrogen (ESR1, ESR2) and progesterone (PGR) receptors in conferring risk of gallbladder cancer. MATERIALS AND METHODS The present case-control study recruited total of 860 subjects, including 410 GBC patients, 230 gallstone patients and 220 controls. We examined the associations of 6 selected polymorphisms in three genes: ESR1 (rs2234693, rs9340799, rs1801132), ESR2 (rs1271572, rs1256049) and PGR (rs1042838) with GBC risk. Genotyping for all the polymorphisms was done using PCR-RFLP. Multifactor dimensionality reduction and classification and regression tree approaches were combined with logistic regression to discover high-order gene-gene interactions in hormonal pathway. RESULTS On comparing the genotype frequency distribution in gallstone and GBC patients with that of healthy subjects, the homozygous variant genotypes of ESR1-397TT (rs2234693) polymorphism showed significant risk for developing gallstone [odds ratio: OR = 2.9] and GBC [OR = 1.8] respectively. Detailed haplotypes analysis suggested that ESR1 T( rs2234693)G( rs9340799)C( rs1801132) have significant association in conferring risk for both gallstones [OR = 2.2] and GBC [OR = 3.0]. However, the variant-containing genotypes (DI+II) of PGR (rs1042838) showed low risk in both GBC [OR = 0.4] and gallstone patients [OR = 0.4].On performing the MDR analysis, ESR1 IVS1-397C>T, ESR1 IVS1-351A>G, and ESR2-789 A>C yielded the highest testing accuracy of 0.634. These results were further supported by the CART analysis which revealed that individuals with the combined genotypes of ESR1-397 CT or TT, ESR1-351 AG or GG and ESR2 -789 AA had the highest risk for GBC [OR = 3.9]. CONCLUSION Using multi-analytical approaches, our study showed important role of ESR1 IVS1-397C>T, ESR1 IVS1-351A>G, and ESR2-789 A>C variants in GBC susceptibility and the risk appears to be mediated through gallstone dependent pathway.

Abstract
There are compelling reasons to conduct studies of cancer in Hispanics, the fastest growing major demographic group in the United States (from 15% to 30% of the U.S. population by 2050). The genetically admixed Hispanic population coupled with secular trends in environmental exposures and lifestyle/behavioral practices that are associated with immigration and acculturation offer opportunities for elucidating the effects of genetics, environment, and lifestyle on cancer risk and identifying novel risk factors. For example, traditional breast cancer risk factors explain less of the breast cancer risk in Hispanics than in non-Hispanic whites (NHW), and there is a substantially greater proportion of never-smokers with lung cancer in Hispanics than in NHW. Hispanics have higher incidence rates for cancers of the cervix, stomach, liver, and gall bladder than NHW. With respect to these cancers, there are intriguing patterns that warrant study (e.g., depending on country of origin, the five-fold difference in gastric cancer rates for Hispanic men but not Hispanic women). Also, despite a substantially higher incidence rate and increasing secular trend for liver cancer in Hispanics, there have been no studies of Hispanics reported to date. We review the literature and discuss study design options and features that should be considered in future studies.

Abstract
INTRODUCTION After a cholecystectomy, the current and traditional practice is to send each resected gallbladder to the pathologist for analysis. Some reports have suggested the possibility of selecting only those gallbladders that need to be analysed. The purpose of this study was to show a simple method for selecting which gallbladders should be sent to the pathologist. METHODS A prospective comparative study was carried out. Two 'tests' were performed in 150 patients to detect or rule out gallbladder cancer. The first test included the patient's variables and a macroscopic gallbladder analysis performed by the surgeon (MGAS). The second test was the analysis performed by the pathologist. The results were compared. RESULTS Of the 150 patients, 132 were women and 18 men; 130 were under 60 years old. One patient had inflammatory bowel disease, seven had changes on ultrasonography and in four cases intra-operative disturbances were observed. During the MGAS, disturbances were found in 30 patients. Eighty-one cases (54%) had at least one or more risk factors for gallbladder cancer.

Abstract
Tissue factor pathway inhibitor-2 (TFPI-2) has been identified as a tumor suppressor gene in several types of cancers, but its role in gallbladder carcinoma (GBC) is yet to be determined. In the present study, TFPI-2 expression in GBC tissues was examined, and its inhibitory activities against GBC growth were evaluated in vitro and in vivo after adenovirus-mediated gene transfer of TFPI-2 (Ad5-TFPI-2) was constructed to restore the expression of TFPI-2 in GBC cell lines (GBC-SD, SGC-996, NOZ) and xenograft tumors. Immunohistochemical staining showed that TFPI-2 was significantly downregulated in GBC tissue specimens. Ad5-TFPI-2 could significantly inhibit GBC growth both in vitro and in vivo. Apoptosis analysis and western blotting assay demonstrated that Ad5-TFPI-2 could induce the apoptosis of both GBC cell lines and tissues by promoting the activities of cytochrome c, Bax, caspase-3 and -9 and suppressing Bcl-2 activity. These data indicated that TFPI-2 acts as a tumor suppressor in GBC, and may have a potential role in gene therapy for GBC.

Abstract
BACKGROUND Biliary tract carcinoma (BTC) is rare in the West, but not uncommon in Asia and is a highly fatal malignancy. VEGF expression is related with poor outcome in patients with BTC. Therefore, we conducted a phase II study to evaluate the efficacy and safety of sunitinib as second-line treatment. METHODS This was a prospective, single-arm, multicentre, multinational study. Patients with unresectable, metastatic BTC who progressed after first-line chemotherapy were eligible. Sunitinib was administered at 37.5mg once daily continuously with 4-week cycle. The primary end point was the time to progression (TTP). RESULTS Between May 2009 and October 2010, a total of 56 patients were enrolled from three countries. The median age was 55 years (range 38-75) and male to female ratio was 37:19. Median TTP was 1.7 months (95% confidence interval (CI) 1.0-2.4). The objective response rate was 8.9% (5 partial response) and disease control rate was 50.0%. (23 stable disease) Grade 3-4 toxicities were observed in 46.4% of the patients with neutropenia and thrombocytopenia being the most frequent (21.4%). CONCLUSIONS This phase II study suggests that sunitinib monotherapy demonstrated marginal efficacy in metastatic BTC patients although toxicity should be concerned in Asian population.
