Abstract
Triple gallbladder represents a rare congenital anatomical abnormality that can be a diagnostic challenge in reason to its rarity and consequential difficulties with diagnosis and identification. A systematic review of all published literature between 1958 and 2022 was performed. We identified 20 previous studies that provided 20 cases of triple gallbladder; our case was also included in the analysis, making a total of 21 patients. All patients underwent on diagnostic imaging examinations. After 1985, 9 patients underwent US examination which allowed prompt recognition of triple gallbladder in 2 patients only. CT was performed in 3 patients and allowed the correct diagnosis in a case. In 4 patients, was performed MRCP which allowed the correct diagnosis of triple gallbladder in all patients. Preoperative imaging allows the recognition of triple gallbladder in 9 of 21 patients (43%); in 12 patients (57%) the diagnosis was intraoperative. On patients considered, 16/21 underwent cholecystectomy. In 15 cases, the excised gallbladders were submitted for histopathological characterization with detection of metaplasia of the mucosa in 3 patients, while papillary adenocarcinoma was found in one. Imaging plays a key role in the identification of the anatomical variants of gallbladder, especially triple gallbladder, as modern imaging techniques allow a detailed assessment of the course of the biliary tract for a correct preoperative diagnosis. It is also crucial to be aware of the association between this condition and the metaplasia phenomena with the development of adenocarcinoma, as this may influence the patient's course of treatment.

Improved long-term outcomes after innovative preoperative evaluation and conception of precise surgery for gallbladder cancer. Cancer Med 2023; 12:18861-18871. [PMID: 37706628 PMCID: PMC10557873 DOI: 10.1002/cam4.6513] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Revised: 05/31/2023] [Accepted: 08/29/2023] [Indexed: 09/15/2023] Open
Abstract
BACKGROUND Three-dimensional visualization preoperative evaluation (3D-VPE) and enhanced recovery after surgery (ERAS) have been suggested to improve outcomes of cancer surgery in patients, yet little is known regarding their clinical benefit in patients with gallbladder cancer (GBC). We hypothesized that the combination of 3D-VPE and ERAS would improve the outcome of patients undergoing surgery for GBC. OBJECTIVE This study aimed to determine if 3D-VPE and ERAS can improve the outcomes and overall survival in patients with GBC, establishing a novel patient management strategy for GBC. METHODS A total of 227 patients with GBC were recruited and divided into two groups: those who received traditional treatment between January 2000 and December 2010 (n = 86; the control group) and those who underwent 3D-VPE and ERAS between January 2011 and December 2017 (n = 141). Univariate and multivariate analyses were employed to assess the relationship among disease stages, lymph node invasion, and cell differentiation between the two groups. Cox regression analysis was used to investigate patient survival in these groups. RESULTS Patients who underwent 3D-VPE and ERAS showed a significantly higher R0 resection rate (67.4% vs. 20.9%, p < 0.001) and dissected lymph node number (26.6 ± 12.6 vs. 16.3 ± 7.6 p < 0.001) compared to the control group. The median survival was 27.4 months, and the 1- and 3-year survival rates were 84.4% and 29.8%, respectively, in patients who received combined management; in the control cohort, the median survival was 12.7 months, and the 1- and 3-year survival rates were 53.5% and 15.1%, respectively. In addition, some postoperative complications and risk factors were diminished relative to the traditionally treated patients. CONCLUSION The implementation of 3D-VPE and ERAS can significantly improve the prognosis and outcomes of patients with GBC and should be considered for wide use in clinical practice.

Abstract
Gallbladder cancer (GBC) is the most common biliary tract cancer worldwide and its incidence has significant geographic variation. A unique combination of predisposing factors includes genetic predisposition, geographic distribution, female gender, chronic inflammation, and congenital developmental abnormalities. Today, incidental GBC is the most common presentation of resectable gallbladder cancer, and surgery (minimally invasive or open) remains the only curative treatment available. Encouragingly, there is an important emerging role for systemic treatment for patients who have R1 resection or present with stage III-IV. In this article, we describe the pathogenesis, surgical and systemic treatment, and prognosis.

Abstract
Gallbladder stones (cholecystolithiasis) are the main risk factor for gallbladder cancer (GBC), a lethal biliary malignancy with poor survival rates worldwide. Gallbladder stones are thought to damage the gallbladder epithelium and trigger chronic inflammation. Preneoplastic lesions that arise in such an inflammatory microenvironment can eventually develop into invasive carcinoma, through mechanisms that are not fully understood. Here, we developed a novel gallbladder preneoplasia mouse model through the administration of two lithogenic diets (a low‐ or a high‐cholesterol diet) in wild‐type C57BL/6 mice over a period of 9 months. Additionally, we evaluated the chemopreventive potentials of the anti‐inflammatory drug aspirin and the cholesterol absorption inhibitor ezetimibe. Both lithogenic diets induced early formation of gallbladder stones, together with extensive inflammatory changes and widespread induction of metaplasia, an epithelial adaptation to tissue injury. Dysplastic lesions were presented only in mice fed with high‐cholesterol diet (62.5%) in late stages (9th month), and no invasive carcinoma was observed at any stage. The cholesterol absorption inhibitor ezetimibe inhibited gallbladder stone formation and completely prevented the onset of metaplasia and dysplasia in both lithogenic diets, whereas aspirin partially reduced metaplasia development only in the low‐cholesterol diet setting. This model recapitulates several of the structural and inflammatory findings observed in human cholecystolithiasic gallbladders, making it relevant for the study of gallbladder carcinogenesis. In addition, our results suggest that the use of cholesterol absorption inhibitors and anti‐inflammatory drugs can be evaluated as chemopreventive strategies to reduce the burden of GBC among high‐risk populations.

Abstract
Background In the World Health Organization (WHO) classification, gallbladder (GB) intraepithelial lesions are grouped as flat or tumoral, according to their morphological features. The purpose of this study was to investigate the relationship between the morphologies and clinical features of GB cancer (GBC) and to examine the feasibility of using morphologic classification as a prognostic factor. Methods From January 2000 to December 2012, the available pathologic slide reviews of 381 patients were analyzed at the Seoul National University Hospital. All pathologic slides were evaluated by two pancreato-biliary tract pathology experts. GBCs were categorized into eight groups (Flat: F1-2, Borderline, Tumoral: Tu1-5), according to the thickness of the mucosal lesion, histologic patterns of the mucosa under microscopy, invasion extent, and patient history of premalignant lesions. According to the morphologic classification, clinical features were compared and survival analysis was performed. Results In three groups, flat lesions comprised 179 (46.9%) cases and borderline and tumoral comprised 97 (25.4%) and 105 (27.5%) cases, respectively. More favorable pathologic and clinical results were found within the tumoral group. The borderline group had an intermediate tendency between flat and intraluminal in clinicopathologic parameters. In the curative resected T2 stage group, the borderline group demonstrated an intermediate trend compared to that of the flat and tumoral groups, but this was statistically insignificant (P=0.08). Conclusions Flat type GBCs show worse prognosis than tumoral GBCs. The morphological classifications between flat and tumoral on the basis of 1 cm and by papillary feature is feasible. Tumor morphology can be used as a reference while deciding the treatment plan, especially in T2 GBC.

Abstract
Background: One of the most common gastrointestinal surgeries is cholecystectomy. Gallstones are the major causes of cholecystectomy and induce various histopathologic changes. Gallbladder carcinoma is rare with poor prognosis. Metaplasic changes in gallbladder epithelium are considered precancerous lesions. Objectives: This study aimed at revealing the spectrum of histopathological patterns of gallbladder diseases in cholecystectomy specimens. Methods: A total of 1004 gallbladder H & E stained slides of cholecystectomy specimens over one year were studied. Histopathological evaluation was done by 6 pathologists in terms of variables. Results: In our study, the male: female ratio was 1:2.1. The age of patients varied from 17 to 96 years with a mean age of 49.1 years. The mean age of patients with gallstones was 47.52 years and was more common in women. Cholesterol, pigmented, and mixed stones were reported in 58.36%, 39.03%, and 2.6% of gallstones, respectively. The most common histological morphology was chronic calculous cholecystitis (61.18%). The incidence of metaplasia and invasive carcinoma was 19.55% and 0.2%, respectively. Conclusions: In this study, histopathological analysis of gallbladder diseases in the cholecystectomy specimens revealed that chronic calculous cholecystitis was the most common histologic finding. Gallstones were found more commonly in women and cholesterol stone was the predominant type. Pyloric metaplasia was the most frequent type of metaplasia. The rate of invasive carcinoma is compatible with those reported in the literature. Routine histopathological analysis of the cholecystectomy specimens will help to detect incidental carcinoma and precursors of malignancy.

Abstract
AIMS Outcomes of colorectal cancer (CRC) treatment and survival have steadily improved during the past decades, accompanied by an increased risk of developing second primary tumours and metastatic tumours at unusual sites. Metastatic CRC can show mucosal colonisation, thereby mimicking a second primary tumour. This potential confusion could lead to incorrect diagnosis and consequently inadequate treatment of the patient. The aim of this study was to differentiate between metastatic CRC and a second primary (gallbladder cancer, GBC) using a combination of standard histopathology and molecular techniques. METHODS AND RESULTS Ten consecutive patients with both CRC and GBC were identified in our region using the Dutch National Pathology Archive (PALGA). Two patients served as negative controls. Histology of GBC was reviewed by nine pathologists. A combination of immunohistochemistry, microsatellite analysis, genomewide DNA copy number analysis and targeted somatic mutation analysis was used to aid in differential diagnosis. In two patients, CRC and GBC were clonally related, as confirmed by somatic mutation analysis. For one case, this was confirmed by genomewide DNA copy number analysis. However, in both cases, pathologists initially considered the GBC as a second primary tumour. CONCLUSIONS Metastatic CRC displaying mucosal colonisation is often misinterpreted as a second primary tumour. A combination of traditional histopathology and molecular techniques improves this interpretation, and lowers the risk of inadequate treatment.

HPB (Oxford) 2019; 21:636-642.

Abstract
BACKGROUND Gallbladder polyp (GBP) surveillance seeks to identify early neoplasms, but practice varies amongst surgical units. Recent European consensus guidelines have recommended an evidence-based GBP surveillance strategy. In a tertiary centre Hepato-Pancreato-Biliary unit we examine GBP surveillance, malignant yield, and assess cost-effectiveness of the new European consensus guidelines. METHODS Respective data were collected from all patients with ultrasonography-detected GBPs between January 2008 and January 2013. RESULTS 558 patients had GBPs detected on ultrasonography. Following initial ultrasonography, 304 (54.5%) had further ultrasonography surveillance of which 168 were in a formal GBP surveillance programme. Pre-malignant/malignant pathology yield was 1.97% with an annual detection rate of 12.0 cases per 1000 GBPs surveyed. Cost-effectiveness analysis of European consensus guidelines calculated annual savings of £209 163 per 1000 GBPs surveyed. Compliance with these guidelines would result in an additional 12.5% of patients under surveillance requiring cholecystectomy. CONCLUSION GBP surveillance uptake was suboptimal at 32.8%. The incidence of pre-malignant/malignant lesions in GBPs emphasises the importance of surveillance for early detection and management with a view to avoiding the poor outcomes associated with more advanced gallbladder cancer. Adherence to the new European consensus guidelines would be clinically cost-effective with significant potential savings demonstrated in this study.

Abstract
INTRODUCTION On occasional cholecystectomies, pathologists encounter incidental dysplasia in the gallbladder mucosa in the sections submitted per protocol for histologic examination. If dysplasia is identified, additional sections are taken and/or the gallbladder is entirely submitted to rule out underlying adenocarcinoma. The aim of our study was to assess the incidence of subsequent identification of invasive adenocarcinoma on additional sections, after an incidentally detected dysplasia was noted on a routine cholecystectomy section. We also aimed to study the significance of the incidental detection of dysplasia and adenocarcinoma, as well as showing the association of gallbladder dysplasia to synchronous or metachronous dysplasia/neoplasia in the biliary tract. MATERIAL AND METHODS Our study was approved by the Institutional Review Board. We retrospectively identified 41 consecutive cases of routine cholecystectomies from 1991 to 2017, which had no clinical suspicion of neoplasia, and did not have any identifiable mass lesion, but on histopathologic analysis, had neoplasia (adenocarcinoma in 4 cases, and dysplasia in 37 cases). The pathologies of all cases were reviewed, and the diagnosis and grade of dysplasia were confirmed. The clinical information was obtained from the electronic medical records. RESULTS Of the 37 cases with dysplasia, 10 (27%) had high-grade dysplasia (HGD) and the remaining showed low-grade dysplasia (LGD). All 4 cases of adenocarcinoma had some gross abnormalities (such as porcelain gallbladder, or ruptured, thickened, and roughened walls, or a granular mucosa). In contrast, none of the 37 cases with dysplasia had any gross abnormality. In 24 (of 37) cases of dysplasia, additional sections were submitted (median 8; ranging from 2 to 29), and in 11 cases, the gallbladder was entirely submitted. None of these cases showed any additional pathologic finding on the extra sections. Interestingly, 7 cases with dysplasia (18.9%; 6 LGD and 1 HGD) were associated with a concomitant pancreatobiliary malignancy. For the remaining 30 cases, follow-up information was available in 16 cases (53.3%) with a mean follow-up of 76.5 months (ranging from 12 to 204 months). None of these showed any subsequent development of pancreatobiliary neoplasms. CONCLUSION Incidentally detected gallbladder dysplasia in a cholecystectomy specimen, without any gross abnormality, has almost no risk of a hidden invasive carcinoma. Although cholecystectomy is sufficient treatment for gallbladder dysplasia, in our study cohort, 18.9% of cases with incidental dysplasia in gallbladder had an associated pancreatobiliary carcinoma, which supports the hypothesis of multifocal neoplastic potential in the pancreatobiliary tree (also known as field effect). Although follow-up on 16 cases shows no subsequent development of any other pancreatobiliary neoplasm, this number is probably not enough to rule out a serial imaging follow-up of patients who have reported dysplasia in their gallbladder, to assess for subsequent development of neoplasia elsewhere in the pancreaticobiliary tree.

Abstract
BACKGROUND The histopathological examination of cholecystectomy specimens has not been standardized with a debate concerning the routine and the selective approach. The aim of this study was to assess the information obtained from routine histopathological examination of cholecystectomy specimens. METHODS All histopathological reports of cholecystectomy specimens between January 2003 and December 2016 were analyzed, including a clinical diagnosis of benign gallstone disease or cholecystitis. RESULTS A total of 20,584 reports were examined. The mean age of patients was 54.2 years. Patients aged more than 60 years represent 37.6% of the study population. Of all patients, 15,973 (77.6%) were females. Incidental gallbladder cancers (GBC) were present in 155 cholecystectomies specimens (0.8%). 67.1% of GBC are at T2 and T3 stage. Granulomatous cholecystitis was diagnosed in only 19 cases (0.1%). GBC were more prevalent in older patients (P < 10-6) and cholesterolosis was more prevalent in young patients (P < 10-6). There was no gender predilection for GBC (P = 0.739). CONCLUSIONS The rate of incidental gallbladder carcinoma in our study is low, yet, we found a higher proportion of T2 and T3 carcinomas stage. Granulomatous cholecystitis may need further investigations and treatments. When a selective approch of histopathological examination of cholecystectomy specimens is used, it is important to take into account that clinical parameters are significantly associated with gallbladder cancer.

Abstract
INTRODUCTION Immunohistochemical (IHC) markers of mucin family are associated with various Gallbladder Lesions (GBLs). AIM To study the distribution of GBL with respect to age and sex as well as to analyse the IHC profile of MUC1 and MUC5AC in GBLs and attempt correlation with clinical and histopathological findings. MATERIALS AND METHODS The present study was conducted over a period of six years. A technique of manual tissue array was employed for cases subjected to IHC using MUC1 and MUC5AC. Results were statistically analysed using software program "The Primer of Biostatistics 5.0". RESULTS A total of 629 GBL were encountered. Out of 605 of non-neoplastic lesions, 32 (5.29%) expressed MUC1 while 515 (85.12%) cases expressed MUC5AC. Out of 24 cases of neoplastic GBL, 20 cases (83.33%) showed positivity for MUC1 and 9 cases (37.5%) were positive for MUC5AC. The rate of MUC1 expression was significantly higher in Gall Bladder Cancer (GBC) {18GB carcinoma (ca) +3 Carcinoma In Situ (CIS)} (85.71%) than chronic cholecystitis (4.71%). The positive rate of MUC5AC expression was significantly lower in GBC (28.57%) than chronic cholecystitis (87.19%). The percentage of cases showing MUC1 expression increased as the severity of disease progressed from hyperplasia to CIS. The percentage of cases showing MUC5AC expression decreased as the severity of disease progressed from hyperplasia to CIS. CONCLUSION In this study, 96.18% cases were non neoplastic GBL of which chronic cholecystitis (87.77%) was predominant. 3.81% of the GBL constituted for neoplastic lesions of which 75% were GBC. MUC1 showed higher rates of expression in neoplastic GBL. MUC5AC showed higher rates of expression in non neoplastic GBL. Expression of MUC1 and MUC5AC might be closely related to pathogenesis of neoplastic and non neoplastic GBL.

Abstract
BACKGROUND Neuroendocrine tumors (NETs) are rare especially in the gallbladder. They have not been elucidated in the pathogenesis, clinicopathological characteristics, and treatment options. CASE PRESENTATION We present a 76-year-old woman with a gallbladder tumor and hepatic hilar lymph node swelling. The lymph node biopsy demonstrated neuroendocrine carcinoma (NEC). We performed cholecystectomy, hepatic hilar lymphadenectomy, extrahepatic biliary duct resection, and hepaticojejunostomy prior to chemotherapy. Pathological examination revealed the gallbladder mass was an adenocarcinoma invading to the muscular layer without any NEC components, whereas the hepatic hilar lymph nodes were filled with high-grade NEC cells with negligible area of adenocarcinoma. The patient received general chemotherapy consisting of carboplatin and etoposide, but a recurrence in the para-aortic lymph nodes occurred 4 months after surgery. CONCLUSIONS We report a rare case of NEC of the hepatic hilar lymph nodes that were concomitant with an adenocarcinoma of the gallbladder. High-grade NEC generally has an aggressive behavior and an optimal treatment strategy should be chosen for each patient.

Abstract
Gallbladder cancer is a lethal disease with notable geographical variations worldwide and a predilection towards women. Its main risk factor is prolonged exposure to gallstones, although bacterial infections and other inflammatory conditions are also associated. The recurrent cycles of gallbladder epithelium damage and repair enable a chronic inflammatory environment that promotes progressive morphological impairment through a metaplasia-dysplasia-carcinoma, along with cumulative genome instability. Inactivation of TP53, which is mutated in over 50% of GBC cases, seems to be the earliest and one of the most important carcinogenic pathways involved. Increased cell turnover and oxidative stress promote early alteration of TP53, cell cycle deregulation, apoptosis and replicative senescence. In this review, we will discuss evidence for the role of inflammation in gallbladder carcinogenesis obtained through epidemiological studies, genome-wide association studies, experimental carcinogenesis, morphogenetic studies and comparative studies with other inflammation-driven malignancies. The evidence strongly supports chronic, unresolved inflammation as the main carcinogenic mechanism of gallbladder cancer, regardless of the initial etiologic trigger. Given this central role of inflammation, evaluation of the potential for GBC prevention removing causes of inflammation or using anti-inflammatory drugs in high-risk populations may be warranted.

Abstract
BACKGROUND The Japanese Society of Hepato-Biliary-Pancreatic Surgery launched the clinical practice guidelines for the management of biliary tract and ampullary carcinomas in 2008. Novel treatment modalities and handling of clinical issues have been proposed after the publication. New approaches for editing clinical guidelines, such as the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, also have been introduced for better and clearer grading of recommendations. METHODS Clinical questions (CQs) were proposed in seven topics. Recommendation, grade of recommendation and statement for each CQ were discussed and finalized by evidence-based approach. Recommendation was graded to grade 1 (strong) and 2 (weak) according to the concept of GRADE system. RESULTS The 29 CQs covered seven topics: (1) prophylactic treatment, (2) diagnosis, (3) biliary drainage, (4) surgical treatment, (5) chemotherapy, (6) radiation therapy, and (7) pathology. In 27 CQs, 19 recommendations were rated strong and 11 recommendations weak. Each CQ included the statement of how the recommendation was graded. CONCLUSIONS This guideline provides recommendation for important clinical aspects based on evidence. Future collaboration with cancer registry will be a key for assessment of the guidelines and establishment of new evidence.

Abstract
Background: The seeds of Macrotyloma uniflorum Lam. (Family Fabaceae) contain extractable total and tannins with reported hepatoprotective, hypocholesterolemic and antioxidant activity. In this study, dietary M. uniflorum seed, methanolic and acetone extracts (ME and AE) were examined for their bile-antilithogenic potential. Materials and Methods: Mice fed with 1% cholesterol and 0.5% cholic acid lithogenic (LG) diet for 8 weeks resulted in cholesterol super saturation in gallbladder bile, which promotes the formation of cholesterol gallstones (CGSs). Results: AE reduced the CGS incidence by 60.21%, and serum total cholesterol, triglyceride (TG), very low density lipoprotein (LDL) and LDL compared to control animals. Seed extracts at 300 mg/kg dose markedly reduced biliary cholesterol (BC) and decreased bile salt content. The ratio of BC to phospholipid which was 2.64 in the LG diet group was reduced to 1.57–1.35 in the M. uniflorum seed extracts treated groups. Liver cholesterol and TG were decreased significantly by feeding of ME and AE at 300 mg/kg dose. AE significantly reversed the changes in apolipoproteins A-I and C-II level disturbed by LG diet. Conclusions: M. uniflorum seed exerted antilithogenic influence by decreasing the cholesterol hyper-secretion into bile and increasing the bile acid output, thus decreasing the formation of LG bile in mice. The effect was maximum in the AE as it also reduced papillary proliferation of gallbladder and fatty degeneration of the liver. The potential antilithogenic effect of the AE of M. uniflorum may be due to antioxidant property of its rich total polyphenol and tannins content.

Abstract
BACKGROUND Causal association of gallbladder stones with gallbladder cancer (GBC) is not yet well established. OBJECTIVE To study the frequency of occurrence of preneoplastic histological lesions and loss of heterozygosity (LOH) of tumor suppressor genes in patients with gallstones. METHODS All consecutive patients with gallstones undergoing cholecystectomy from 2007-2011 were included prospectively. Histological examination of the gallbladder specimens was done for preneoplastic lesions. LOH at 8 loci, that is 3p12, 3p14.2, 5q21, 9p21, 9q, 13q, 17p13, and 18q for tumor suppressor genes (DUTT1, FHIT, APC, p16, FCMD, RB1, p53, and DCC genes) that are associated with GBC was tested from microdissected preneoplastic lesions using microsatellite markers. These LOH were also tested in 30 GBC specimens. RESULTS Of the 350 gallbladder specimens from gallstone patients, hyperplasia was found in 32%, metaplasia in 47.8%, dysplasia in 15.7%, and carcinoma in situ in 0.6%. Hyperplasia, metaplasia, and dysplasia alone were found in 11.7%, 24.6%, and 1.4% of patients, respectively. A combination of hyperplasia and dysplasia, metaplasia and dysplasia, and hyperplasia, metaplasia, and dysplasia was found in 3.4%, 6.3%, and 4.3% of patients, respectively. LOH was present in 2.1% to 47.8% of all the preneoplastic lesions at different loci. Fractional allelic loss was significantly higher in those with dysplasia compared with other preneoplastic lesions (0.31 vs 0.22; P = 0.042). No preneoplastic lesion or LOH was found in normal gallbladders. CONCLUSIONS Patients with gallstones had a high frequency of preneoplastic lesions and accumulation of LOH at various tumor suppressor genes, suggesting a possible causal association of gallstones with GBC.

Abstract
Gallbladder cancer, although regarded as the most common malignancy of the biliary tract, continues to be associated with a dismal overall survival even in the present day. While complete surgical removal of the tumour offers a good chance of cure, only a fraction of the patients are amenable to curative surgery owing to their delayed presentation. Moreover, the current contribution of adjuvant therapies towards prolonging survival is marginal, at best. Thus, understanding the biology of the disease will not only enable a better appreciation of the pathways of progression but also facilitate the development of an accurate genetic model for gallbladder carcinogenesis and dissemination. This review provides an updated, evidence-based model of the pathways of carcinogenesis in gallbladder cancer and its dissemination. The model proposed could serve as the scaffolding for elucidation of the molecular mechanisms involved in gallbladder carcinogenesis. A better understanding of the pathways involved in gallbladder tumorigenesis will serve to identify patients at risk for the cancer (and who thus could be offered prophylactic cholecystectomy) as well as aid oncologists in planning the most suitable treatment for a particular patient, thereby setting us on the vanguard of transforming the current treatment paradigm for gallbladder cancer.

[PMID: 24768494 DOI: 10.1016/j.anndiagpath.2014.03.004] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2014] [Revised: 03/25/2014] [Accepted: 03/25/2014] [Indexed: 01/27/2023]
Abstract
Gallbladder dysplasia and carcinoma (GBDC) vary greatly in incidence worldwide. We aimed to determine their prevalence in an Irish population, to assess the influence of tissue sampling protocols upon GBDC diagnosis, and to correlate various macroscopic and microscopic features with GBDC. We retrospectively reviewed histology reports of cholecystectomy specimens accessioned from 2000 to 2013. A total of 2522 cholecystectomy reports were reviewed, from 1860 female and 662 male patients. Male patients were significantly older (54.8 vs 46.8 years). There were 29 cases of dysplasia (1.15%) and 12 cases of carcinoma (0.48%), of which 10 were primary gallbladder cancers (0.4%). In 83.4% of cases, there was pathologic or radiologic evidence of cholelithiasis. Histologic findings included chronic (91.1%) or acute (15.4%) cholecystitis, cholesterosis (10.9%), adenomyomatous hyperplasia (2.1%), xanthogranulomatous inflammation (2.02%), and "porcelain" gallbladder (0.2%). Patients with GBDC were more likely to have a macroscopically identifiable lesion (29.4% vs 1.8%, positive predictive value, 18.18%, negative predictive value, 99.03%). Gallbladder dysplasia and carcinoma patients also had larger gallstones (median, 19 vs 12 mm) and were more likely to have adenomyomatous hyperplasia (8.8% vs 2.05%). When cases with a macroscopically identifiable lesion or clinical details suggestive of a gallbladder tumour were excluded (n = 2385), GBDC was significantly more frequently diagnosed if multiple tissue blocks had been sampled (2.91% vs 0.76%; relative risk (RR), 3.836). Rates of GBDC in Irish cholecystectomy specimens are low. The absence of a macroscopically identifiable lesion has a high (but not 100%) negative predictive value for GBDC. Sampling with more than 1 block significantly increases pickup rates of GBDC in these cases.

Predictive factors for incidental gallbladder dysplasia and carcinoma. J Surg Res 2014; 189:17-21. [PMID: 24589178 DOI: 10.1016/j.jss.2014.01.064] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2013] [Revised: 12/14/2013] [Accepted: 01/31/2014] [Indexed: 12/14/2022]
Abstract
BACKGROUND This study aims to analyze clinical characteristics and demographics of all patients admitted for cholecystectomy in a tertiary referral center to determine predictors of incidental gallbladder dysplasia (IGBD) and incidental gallbladder carcinoma (IGBC). METHODS A retrospective analyses of clinical, demographic, and histologic features of patients undergoing cholecystectomy in a single tertiary institution from 2005-2012 were performed using a logistic regression model to determine the predictors of IGBD and IGBC. RESULTS Some 771 (28 conversions to open surgery [3.6%]) and 93 patients (10.7%) underwent laparoscopic and open cholecystectomies for gallstone disease, respectively. At final pathology, IGBD (low-grade [n = 10], high-grade [n = 2], mixed-grade [n = 1], and adenoma-associated [n = 5] dysplasia) was found in 18 patients (2%; median age, 45 y; interquartile range, 42.5-63.5; male-to-female ratio, 1:2; six Caucasian; and 12 Asian). IGBC was found in seven patients (0.8%; median age, 69 y; interquartile range, 69-72; one Afro-Caribbean; four Caucasian; and two Asian). Logistic regression analysis revealed Asian patients to be at a higher risk of IGBD (odds ratio [OR], 2.9; 95% confidence interval [CI], 1.1-8.0; P = 0.02). Only age (OR, 1.12; 95% CI, 1.04-1.2; P < 0.01) and polypoid lesions (OR, 37.4; 95% CI, 2.97-470.6; P = 0.01) were significantly associated with IGBC. Receiver operating characteristic curve analysis demonstrated that age >68 y correlated positively to IGBC. CONCLUSIONS IGBD and IGBC are fairly common incidental histologic finding after cholecystectomy for gallstone disease. When considering cholecystectomy, patients' demographics, in particular age and race, should always be considered as this might help the surgeon and the pathologist to institute the appropriate treatment.

Abstract
Aberrations in telomere length and telomere maintenance contribute to cancer development. In this article, we review the basic principles of telomere length in normal and tumor tissue and the presence of the two main telomere maintenance pathways as they pertain to gastrointestinal tract cancer. Peripheral blood telomeres are shorter in patients with many types of gastrointestinal tract cancers. Telomere length in tumor DNA also appears to shorten early in cancer development. Tumor telomere shortening is often accompanied by telomerase activation to protect genetically damaged DNA from normal cell senescence or apoptosis, allowing immortalized but damaged DNA to persist. Alternative lengthening of telomeres is another mechanism used by cancer to maintain telomere length in cancer cells. Telomerase and alternative lengthening of telomeres activators and inhibitors may become important chemopreventive or chemotherapeutic agents as our understanding of telomere biology, specific telomere-related phenotypes and its relationship to carcinogenesis increases.

Abstract
BACKGROUND Gallbladder diseases present with cholelithiasis in a wide spectrum of adenomas and cancers. Two or three specimens are sampled in cholecystectomies in routine pathology practice. The aim of this study was to investigate the increase in frequency of histologic alterations in cholecystectomies, particularly precancerous lesions, by increasing the sample size to understand the carcinoma pathway. METHODS Cholecystectomies of 432 patients with pathology records and materials from two medical centers were collected, and two groups were created. Initial data with two or three samples were allocated to Group 1 and the new six samples with the initial ones were allocated to Group 2. Hematoxylin and eosin (HandE) sections were examined for histopathologic alterations, and periodic acid-Schiff (PAS) Alcian blue (pH 2.5) and high iron diamine (pH 2.5) stains were used to signify the mucin profile in case of metaplasias. For the comparison of findings, non-parametric tests, McNemar's tests, chi-squared tests and Fisher's exact test were performed. RESULTS Of the 432 patients, 308 (71.3%) patients were female and 124 (28.7%) patients were male. The mean age of patients was 47.9±14.6 years. Cholesterolosis was observed in 95 (22%) patients in Group 1 and 108 (25%) patients in Group 2. Gallstones were detected in 255 (59%) of the cholecystectomies. There was a significant difference between Group 1 and Group 2 by increasing the sample size when we compared cholesterolosis, metaplasia and polyps (P<0.05). Cholecystitis and dysplasia rates were the same in both of the groups. There was no cancer determined. CONCLUSION Increasing the sample size in cholecystectomies increased the diagnosis of some histologic alterations, but further studies with a larger number of samples over a longer period time might increase the ability to determine precancerous lesions and concomitants.

A comparative study of clinicopathological features between chronic cholecystitis patients with and without Helicobacter pylori infection in gallbladder mucosa. PLoS One 2013; 8:e70265.

Abstract
Background Helicobacter pylori has been isolated from 10%–20% of human chronic cholecystitis specimens but the characteristics of “Helicobacter pylori positive cholecystitis” remains unclear. This study aims to compare the clinicopathological features between chronic cholecystitis patients with and without Helicobacter pylori infection in gallbladder mucosa. Methods Three hundred and twenty-six chronic cholecystitis patients were divided into two groups according to whether Helicobacter pylori could be detected by culture, staining or PCR for Helicobacter 16s rRNA gene in gallbladder mucosa. Positive samples were sequenced for Helicobacter pylori-specific identification. Clinical parameters as well as pathological characteristics including some premalignant lesions and the expression levels of iNOS and ROS in gallbladder were compared between the two groups. Results Helicobacter pylori infection in gallbladder mucosa was detected in 20.55% of cholecystitis patients. These patients had a higher prevalence of acid regurgitation symptoms (p = 0.001), more histories of chronic gastritis (p = 0.005), gastric ulcer (p = 0.042), duodenal ulcer (p = 0.026) and higher presence of Helicobacter pylori in the stomach as compared to patients without Helicobacter pylori infection in the gallbladder mucosa. Helicobacter pylori 16s rRNA in gallbladder and gastric-duodenal mucosa from the same individual patient had identical sequences. Also, higher incidences of adenomyomatosis (p = 0.012), metaplasia (p = 0.022) and higher enhanced expressions of iNOS and ROS were detected in Helicobacter pylori infected gallbladder mucosa (p<0.05). Conclusions Helicobacter pylori infection in gallbladder mucosa is strongly associated with Helicobacter pylori existed in stomach. Helicobacter pylori is also correlated with gallbladder premalignant lesions including metaplasia and adenomyomatosis. The potential mechanism might be related with higher ROS/RNS production but needs further investigation.

Abstract
Background Selective approach for sending cholecystectomy specimens for histopathology results in missing discrete pathologies such as premalignant benign lesions such as porcelain gallbladder, carcinoma-in-situ, and early carcinomas. To avoid such blunders therefore, every cholecystectomy specimen should be routinely examined histologically. Unfortunately, the practice of discarding gallbladder specimen is standard in most tertiary care hospitals of Pakistan including the primary investigators’ own institution. This study was conducted to assess the feasibility or otherwise of performing histopathology in every specimen of gallbladder. Methods This cohort study included 220 patients with gallstones for cholecystectomy. All cases with known secondaries from gallbladder, local invasion from other viscera, traumatic rupture of gallbladder, gross malignancy of gallbladder found during surgery was excluded from the study. Laparoscopic cholecystectomy was performed in majority of cases except in those cases where anatomical distortion and dense adhesions prevented laparoscopy. All gallbladder specimens were sent for histopathology, irrespective of their gross appearance. Results Over a period of two years, 220 patients with symptomatic gallstones were admitted for cholecystectomy. Most of the patients were females (88%). Ninety two per cent patients presented with upper abdominal pain of varying duration. All specimens were sent for histopathology. Two hundred and three of the specimens showed evidence chronic cholecystitis, 7 acute cholecystitis with mucocele, 3 acute cholecystitis with empyema and one chronic cholecystitis associated with poly. Six gallbladders (2.8%) showed adenocarcinoma of varying differentiation along with cholelithiasis. Conclusion The histopathological spectrum of gallbladder is extremely variable. Incidental diagnosis of carcinoma gall bladder is not rare; if the protocol of routine histopathology of all gallbladder specimens is not followed, subclinical malignancies would fail to be identified with disastrous results. We strongly recommend routine histopathology of all cholecystectomy specimens.

Abstract
CONTEXT Advanced gallbladder carcinoma (GBC) is a highly fatal disease with poor prognosis and few therapeutic alternatives. The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that plays a central role in cell growth and homeostasis. Its regulation is frequently altered in various tumors and is an attractive target for cancer therapy; however, its status in GBC remains unclear. OBJECTIVE To characterize immunohistochemical expression and prognostic significance of phospho-mTOR in advanced gallbladder carcinoma. DESIGN Phospho-mTOR expression was examined by immunohistochemistry in tissue microarrays containing 128 advanced GBCs and 99 cases of chronic cholecystitis, which were divided into 2 groups according to the presence or absence of metaplasia. To evaluate the association of the level of phospho-mTOR expression with clinical variables and patient survival, the advanced GBCs were classified as having low or high expression. Statistical analysis was performed by using a significance level of P < .05, and Kaplan-Meier curves were constructed for survival analysis. RESULTS Immunostaining for phospho-mTOR was positive in 82 of 128 tumors (64.1%) and in 24% of chronic cholecystitis cases (16% nonmetaplasia and 32% with metaplasia) (P < .001). Survival analysis indicated that a high phospho-mTOR immunohistochemical expression was associated with poorer prognosis in patients with advanced GBC (P = .02). CONCLUSIONS Metaplasia is a common finding in chronic cholecystitis and is considered a precursor lesion of dysplasia. Our results suggest that the activation of mTOR occurs very early during the development of GBC, contributing to the carcinogenesis process. Phospho-mTOR expression is correlated with poor survival, supporting the potential of mTOR for targeted therapy.

Abstract
INTRODUCTION We report the frequency and age of metaplasia, dysplasia and carcinoma of the gallbladder, and seek to establish a sequence of progression of these, since several studies suggest that this is the carcinogenesis pathway. MATERIAL AND METHODS Descriptive retrospective cross-sectional study over a period of 4 years, with an analytical component of 1,514 patients with cholelithiasis, in whom cholecystectomy were performed. RESULTS The mean age of the sample was 46 years and 72% of patients were female. The prevalence (and mean age) of pyloric metaplasia, intestinal metaplasia, dysplasia and carcinoma was 22.6 (47), 2.1 (46), 0.2 (54) and 0.6% (63 years), respectively. There was a significant association between intestinal and pyloric metaplasia (P<.001, chi(2)) and between dysplasia and carcinoma (P<.005, Yates), but not between metaplasia and dysplasia. CONCLUSION Improved studies should be conducted for the correct interpretation of the pathogenesis of gallbladder cancer.

Abstract
The neoplasms of the biliary tree include the carcinomas of the intra- and extrahepatic bile ducts, the gallbladder and the ampulla. Two types of precancerous lesions precede these adenocarcinomas: the flat and non-tumour forming type that is called biliary intraepithelial neoplasia, and the papillary and tumour-forming type that has been named intraductal papillary neoplasm of the bile duct. Rarely also biliary mucinous cystic neoplasm can give rise to invasive biliary adenocarcinomas. This review discusses the pathological, molecular, epidemiological, clinical and prognostic features of the precancerous biliary lesions, separated according to their origin in the bile ducts, the ampulla and the gall bladder.

Abstract
Incidentally discovered gallbladder cancer (IGBC) is defined as the gallbladder cancer (GBC) diagnosed during or after the cholecystectomy done for unsuspected benign gallbladder disease. Laparoscopic cholecystectomy (LC) is the most common procedure performed for benign gallbladder disease worldwide. Majority of GBC patients have associated gallstones. With the advent of ultrasonography more patients are being diagnosed with gallstones and are being subjected to cholecytectomy. IGBC is found in 0.2-2.9 % of all cholecytectomies done for gallstone disease. It represents 27-41 % of all GBC. Patients with IGBC having Tis and T1a stage, with negative cystic duct margin can be treated by simple cholecystectomy alone. Patients with stage T1b and beyond should undergo restaging, and should be treated with radical re - resection (R0). Residual disease is found in 40-76 % patients on re-exploration. The survival rates of patients undergoing re resection for IGBC is similar to those undergoing primary radical surgery. LC is contraindicated in patients with GBC. Patients presenting post LC should undergo radical re- resection and additional port site excision, as they have a high incidence of port site metastasis. At cholecystectomy for benign gallbladder disease all gallbladder specimens should be opened before closing abdomen and if available all suspicious specimens should be sent for immediate frozen section. All gallbladder specimens should be subjected to histopathology examination to avoid missing GBC. The surgeon should have a high index of suspicion for GBC if encountering difficult cholecystectomy for a benign disease, and in patients with atypical clinical and ultrasound findings in high incidence areas.

Abstract
Gallbladder cancer (GBC) is the leading cause of cancer related mortality in certain geographic areas. Most of the patients with GBC have advanced disease at presentation, precluding curative resection resulting in a dismal prognosis. However, recent advances in the understanding of its epidemiology and pathogenesis coupled with development of newer diagnostic tools and therapeutic options, has resulted in enhanced optimism towards the management of the disease. The leading risk factors are gallstones, advancing age, female gender, anomalous pancreaticobiliary ductal junction, certain ethnic groups and geographic populations. Advances in radiological imaging and the advent of endoscopic ultrasound have facilitated early detection and accurate staging of the tumor. A high index of suspicion in high risk groups is necessary to pick up incidental and early GBC, as surgical resection is curative. In patients with suspected GBC, an open surgical resection that is appropriate for that stage is advocated. Adjuvant combination chemotherapy and molecular targeted therapy are emerging as effective therapeutic options in those with advanced GBC. Endoscopic palliation of biliary and gastric outlet obstruction with metallic stents has improved their quality of life. Prevention remains the hitherto less explored option to reduce GBC related mortality. Prophylactic cholecystectomy in high risk groups is a cost-effective option. A multi-disciplinary systematic global approach to initiate collaborative ventures to understand epidemiology, standardize management strategies, conduct multi-centric trials with newer therapeutic agents and initiate preventive measures, would pave way for the future conquest of the disease.

World J Gastroenterol 2012; 18:1208-15.

Abstract
AIM: To determine the expression of HER2 and bradykinin B1 receptors (B1R) in the two pathogenic models of gallbladder cancer: the metaplasia-dysplasia-carcinoma and the adenoma-carcinoma pathways.
METHODS: Receptor proteins were visualized by immunohistochemistry on 5-μm sections of paraffin-embedded tissue. Expression of both receptors was studied in biopsy samples from 92 patients (6 males and 86 females; age ranging from 28 to 86 years, mean 56 years). High HER2 expression in specimens was additionally investigated by fluorescence in situ hybridization. Cell proliferation in each sample was assessed by using the Ki-67 proliferation marker.
RESULTS: HER2 receptor protein was absent in adenomas and in normal gallbladder epithelium. On the contrary, there was intense staining for HER2 on the basolateral membrane of epithelial cells of intestinal metaplasia (22/24; 91.7%) and carcinoma in situ (9/10; 90%), the lesions that displayed a significantly high proliferation index. Protein up-regulation of HER2 in the epithelium with metaplasia or carcinoma in situ was not accompanied by HER2 gene amplification. A similar result was observed in invasive carcinomas (0/12). The B1R distribution pattern mirrored that of HER2 except that B1R was additionally observed in the adenomas. The B1R appeared either as cytoplasmic dots or labeling on the apical cell membrane of the cells composing the epithelia with intestinal metaplasia (24/24; 100%) and carcinoma in situ (10/10; 100%) and in the epithelial cells of adenomas. In contrast, both HER2 (4/12; 33%) and B1R (1/12; 8.3%) showed a low expression in invasive gallbladder carcinomas.
CONCLUSION: The up-regulation of HER2 and B1R in precursor lesions of gallbladder carcinoma suggests cross-talk between these two receptors that may be of importance in the modulation of cell proliferation in gallbladder carcinogenesis.

Abstract
Precursor lesions of pancreatobiliary cancer can be divided into cystic and flat lesions. Mucinous cystic neoplasm and intraductal papillary mucinous neoplasm (IPMN) comprise the cystic precursors in the pancreas, while intraductal papillary neoplasm (IPN) represents their counterpart in the bile duct system. There is an adenoma-carcinoma sequence in the cystic precursors arising from four different types of epithelia: pancreatobiliary, oncocytic, intestinal and gastric. These subtypes of IPMN/IPN are morphologically and immunohistochemically well characterised and show clinical and prognostic relevance: the gastric subtype is associated with the best prognosis, followed by the oncocytic and intestinal subtypes, while the pancreatobiliary subtype is characterized by adverse clinical behaviour. Pancreatic intraepithelial neoplasia (PanIN) and biliary intraepithelial neoplasia (BilIN) represent the flat precursors. PanIN are morphologically and biologically well defined. PanIN with lobulocentric atrophy has recently been described as a putative precursor of pancreatic cancer. Despite well defined morphological features in BilIN, the molecular alterations seen during early tumor progression in the biliary tract are poorly understood.

Abstract
A 48 year-old African American woman presented to her physician complaining of a rapidly evolving epigastric and right upper quadrant abdominal pain. A PET-CT of the abdomen and pelvis demonstrated hypermetabolic, polypoid masses within the gallbladder and several tumors in the left lobe of the liver for which she underwent diagnostic laparoscopy. The gallbladder revealed a 3.5 × 3.3 × 2.4 tan-brown exophytic mass located at the fundus and growing into the lumen with multiple contiguous papillary projections arising from the mucosal surface. A concurrent large cell neuroendocrine carcinoma and papillary adenocarcinoma of the gallbladder was revealed histologically. There was shared reactivity to antibodies directed against the distinct antigens for each morphological component with transitional tumor cells (of both histological components) located at the areas where the two tumor types merged, revealing common immunoreactivity for carcinoembryonic antigen, cancer antigen 19-9, keratin 19, c-kit (cluster of differentiation protein 117 (CD117)) and epithelial cell adhesion molecule. Ultrastructurally, individual cells were demonstrated to have overlapping features of neuroendocrine and glandular differentiation. The aforementioned histological, ultrastructural and immunohistochemical profile is strongly suggestive of a biphenotypic stem/progenitor cell tumor of the gallbladder.

Abstract
Cancer of the gallbladder, a rare entity with a poor prognosis, is often discovered incidentally during or after cholecystectomy. It tends to disseminate early via lymphatic, peritoneal, endobiliary, and hematogenous pathways. Diagnosis is made intra-operatively in only a quarter of cases, by examination of the opened cholecystectomy specimen in the operating room by the surgeon; this procedure should be routine. For incidentally-discovered cancers, survival was 28% at five years. Prognostic factors include age, TNM stage, gallbladder perforation during cholecystectomy and less-than-optimal resection at re-operation. Whether the laparoscopic route for the initial cholecystectomy has an impact on survival remains a subject of debate. R0 surgery is the only potentially curative treatment: simple cholecystectomy with clear margins is adequate resection for stage T1a tumors; extended cholecystectomy with lymphadenectomy and possibly resection of the bile duct is required for more advanced stages. After curative resection, neo-adjuvant or adjuvant chemotherapy and radiotherapy have not, so far, proven effective. Improvement of surgical practices (systematic review of cholecystectomy specimens in the OR, prevention of gallbladder perforation with bile spillage during surgery, early re-intervention for optimal resection) could improve the prognosis of these cancers.

Abstract
Excess body weight (EBW) is an independent risk factor for many human malignancies, including cancers throughout the gastrointestinal and hepatobiliary tract from the esophagus to the colorectum. The relative risk of gastrointestinal cancer in obese individuals is approximately 1.5-2.0 times that for normal weight individuals, with organ-specific and gender-specific differences for specific cancers. The association between EBW and risk of premalignant stages of gastrointestinal carcinogenesis, such as colorectal adenoma and Barrett esophagus, is similar, implying a role for EBW during the early stages of carcinogenesis that could be relevant to preventative strategies. EBW also impacts negatively on gastrointestinal cancer outcomes. The mechanistic basis of the association between EBW and carcinogenesis remains incompletely understood. Postulated mechanisms include increased insulin and insulin-like growth factor signaling and chronic inflammation (both linked to the metabolic syndrome), as well as signaling via adipokines, such as leptin. The role of obesity-related changes in the intestinal microbiome in gastrointestinal carcinogenesis deserves further attention. Whether weight loss leads to reduced future gastrointestinal and liver cancer risk has yet to be fully explored. There is some support for the idea that weight loss negatively regulates colorectal carcinogenesis. In addition, data suggest a reduction in risk of several cancers in the first 10 years after bariatric surgery.

Intestinal phenotypes in pediatric gallbladder epithelium. Hum Pathol 2011; 42:1454-8.

Abstract
The aim of this study was to characterize the physiologic expression of "intestinal" features in gallbladders of infants and children. The study group consisted of 56 pediatric (age, 2 weeks to 7 years) and 15 adult (15-25 years) patients who underwent incidental cholecystectomy during surgery for other lesions. All gallbladders examined were histologically unremarkable without inflammation, gallstones, or neoplasia. The presence of goblet cells and the expression of cytokeratin 7, cytokeratin 20, mucin core protein 2, and caudal-related homeobox protein 2 were examined. Intestinal features were frequently detected in the pediatric gallbladders: goblet cells in 34 cases (61%), cytokeratin 20 expression in 25 (45%), mucin core protein 2 expression in 32 (57%), and caudal-related homeobox protein 2 expression in 16 (29%). In contrast, none of these features was identified in adult gallbladders. The expression of mucin core protein 2 was mostly restricted to goblet cells in pediatric gallbladders, whereas cytokeratin 20 and caudal-related homeobox protein 2 were expressed in both goblet and nongoblet cells. Cytokeratin 7 was diffusely and consistently expressed in both pediatric and adult gallbladder epithelium including goblet cells. Intestinal features became less frequent with age and were scarce in children aged 6 to 7 years. Thus, goblet cells were identified in 14 (93%) of 15 children aged <1 year, together with the common expression of cytokeratin 20 (73%), mucin core protein 2 (93%), and caudal-related homeobox protein 2 (53%). In conclusion, intestinal features are physiologically present in gallbladder epithelium of children, particularly those aged <6 years. Intestinal metaplasia, as associated with cholangiopathy or carcinogenesis in adult patients, may represent an immature phenotype of biliary epithelium.

Abstract
PURPOSE Pancreaticobiliary maljunction (PBM) is associated with an increased frequency of gallbladder malignancy. Intestinal metaplasia is often observed in gallbladder disease and is a risk factor for gallbladder carcinoma in adults. The hyperplasia-dysplasia-carcinoma progression is one of the possible mechanisms involved in biliary carcinogenesis. In this study, we evaluate the gallbladders of children with PBM for intestinal metaplasia and other histological changes. METHODS From January 1997 to July 2010, 45 children with PBM were treated at our institution. A total of 42 children were included in our analysis which included histology and medical record review. RESULTS The median age was 2.9 years (range 1 month-16.5 years). The most common histological finding was villous-type mucosal hyperplasia, found in 24 patients (57.1%). Mucous gland metaplasia and goblet cell metaplasia were observed in 12 (28.6%) and 7 (16.7%) patients, respectively. There were no cases of malignancy. The intra-gallbladder amylase level in patients with mucosal hyperplasia was significantly elevated (81,373 ± 92,442 vs. 38,932 ± 61,466; p = 0.042). Patients with mucous gland metaplasia had significantly higher serum amylase levels (833 ± 1,214 vs. 343 ± 358; p = 0.024). CONCLUSION The incidence of intestinal metaplasia is relatively high even in children with PBM. Such mucosal changes are related to cholangitis resulting from the regurgitation of pancreatic juice into the bile duct, which also causes hyperamylasemia via cholangio-venous reflux.

Abstract
Biliary tract cancers (BTC), which encompass intra- and extrahepatic cholangiocarcinomas and gallbladder carcinomas, are a genetically diverse collection of cancers. Evidence suggests distinct models of molecular and pathologic progression, and a growing body of genetics data points to a heterogeneous collection of underlying mutations in key oncogenes and tumor suppressor genes. Although tumor genetics have been used to tailor individual treatment regimens and guide clinical decision making in other cancers, these principles have not been applied in BTC. Recent clinical trials with targeted therapies seem promising, although the relationships between subsets of patients with positive responses to therapy and tumor genetics remain unexplored. Here, we summarize the molecular pathogenesis and genetics of BTCs and animal modeling and relate these to recent and ongoing clinical trials with targeted agents.

Abstract
BACKGROUND While gallstones are associated with cancers of the gallbladder, the actual nature of their relationship needs to be clarified. This would aid the recommendations on the need for prophylactic cholecystectomy. METHODS A systematic search of the scientific literature was carried out using the Medline, the Embase, and the Cochrane Central Register of Controlled Trials for the years 1891-2009 to obtain access to all publications involving gallstones in gallbladder cancer. RESULTS While some epidemiological evidence supports a causal relationship for gallstones in gallbladder cancer, other studies have demonstrated a relatively low incidence of gallbladder cancer in countries reporting a high incidence of gallstones as a whole. In those studies where gallstones appear to have a causative role for cancer, the risk increases with increasing size, volume and weight, and number of the stones. The impact of duration of the stone or its composition is not clear. Experimental evidence from studies examining the impact of artificially introducing gallstones in the gallbladder has failed to lead to carcinogenesis. CONCLUSIONS The evidence at the current time indicates that gallstones are a cofactor in the causation of gallbladder cancer. Absolute proof of their role as a cause for gallbladder cancer is lacking. The recommendation for prophylactic cholecystectomy in countries reporting a high incidence of gallbladder cancer and associated gallstones needs to be tailored to the epidemiological profile of the place.

Abstract
INTRODUCTION Gallbladder cancer, which is characterized by rapid progression and a poor prognosis, is a complex disease to treat. Unfortunately, little is known currently about its etiology or pathogenesis. A better understanding of its carcinogenesis and determining risk factors that lead to its development could help improve the available treatment options. METHOD Based on this better understanding, the histological alterations (such as acute cholecystitis, adenomyomatosis, xanthogranulomatous cholecystitis, polyps, pyloric metaplasia, intestinal metaplasia, dysplasia, cancer and others) in gallbladders from 1,689 patients who underwent laparoscopic cholecystectomy for cholecystolithiasis were analyzed. The association of these gallbladder histological alterations with clinical data was studied. RESULTS Gender analysis revealed a greater incidence of inflammatory changes in males, while dysplasia and cancer were only found in women. The incidence of cholesterolosis was greater in the patients 60 years of age and under, and the incidence of adenomyomatosis and gangrene was greater in the elderly patients. A progressive increase in the average age was observed as alterations progressed through pyloric metaplasia, intestinal metaplasia, dysplasia and then cancer, suggesting that the metaplasia-dysplasia-carcinoma sequence may occur in gallbladder cancer. Gallbladder histological alterations were also observed in asymptomatic patients. CONCLUSION The results of this study suggest that there could be an association between some histological alterations of gallbladder and cancer, and they also suggest that the metaplasia-dysplasia-carcinoma sequence could in fact be true in the case of gallbladder cancer. Nevertheless, further studies directed towards a perfect understanding of gallbladder carcinogenesis are required.

Abstract
We reported previously that intestinal metaplasia in the gallbladder is strongly associated with expression of caudal-related homeobox transcription factor Cdx2. It has been documented that occult pancreatobiliary reflux, even in the absence of pancreaticobiliary maljunction, is associated with elevated risk of biliary malignancy. We ascertained the correlation between intestinal metaplasia in the gallbladder and occult pancreatobiliary reflux. In 196 patients with a normal pancreaticobiliary ductal arrangement who had undergone laparoscopic cholecystectomy, we performed intraoperative cholangiography and measured amylase levels in bile sampled from the gallbladder. The cutoff value for high cystic amylase was defined as a biliary amylase level higher than the normal upper limit of serum amylase (215 IU/L). We also retrospectively reviewed the cholecystectomized tissue specimens to investigate the presence of intestinal metaplasia and expression of Cdx2. Then, we explored the relationship between intestinal metaplasia in the gallbladder and occult choledocho-pancreatic reflux. Intestinal metaplasia was found in 16.8% (33/196) of the gallbladders. The prevalence of choledocho-pancreatic reflux revealed by intraoperative cholangiography was not significantly different between cases with intestinal metaplasia (5/33, 15.2%) and those without (25/163, 15.3%; P = .81). However, in cases with intestinal metaplasia, the rate of high cystic amylase (13/33, 39.4%) was significantly higher compared with cases without intestinal metaplasia (26/163, 16.0%, P = .005). In conclusion, intestinal metaplasia in the gallbladder is significantly correlated with high amylase levels in bile in patients with a morphologically normal pancreaticobiliary ductal arrangement.

Abstract
Gallbladder cancer (GBC) shows a marked geographical variation in its incidence, with the highest figures being seen in India and Chile and relatively low levels in many Western countries. Risk factors for its development include the presence of gallstones, infection and the presence of an anomalous pancreatobiliary ductal junction. It can arise from either a pathway involving metaplasia or dysplasia or one in which there is a pre-existing adenoma. The former is the more common and, because it is often not associated with a macroscopically recognizable lesion, leads to the recommendation that all gallbladders need to be examined microscopically. Accurate staging of invasive cancers is essential to determine prognosis and treatment, and this requires extensive tumour sampling. A number of genetic alterations have been identified in the preinvasive and invasive stages of GBC and they support the morphological evidence of there being two pathways by which tumours develop. Some of these genetic changes are associated with particular risk factors. For example, cases with anomalous pancreatobiliary ductal junction show a higher frequency of K-ras mutations. Some changes are associated with differences in prognosis. For example, cancers without expression of p21 but with expression for p27 have a better prognosis, whereas those that express c-erb-B2 have a worse one. Work has also been done on identifying clinical, imaging and other factors that indicate that patients have a higher risk of having GBC. This is particularly important in high-incidence areas in which GBC is a significant public health problem.

Abstract
CONTEXT AND OBJECTIVE Gallbladder cancer is usually diagnosed at a late stage and generally results in death. Discovery of predisposing factors for this neoplasia could prevent this outcome. In this study, we assess the presence of one of these factors: intestinal metaplasia in gallbladders with stones and inflammatory processes. DESIGN AND SETTING Cross-sectional study in Hospital do Servidor Público Estadual de São Paulo. METHOD The first 80 gallbladders from patients who underwent elective cholecystectomy between April and August 2002, presenting stones and chronic inflammation, were studied. The patients were divided into groups according to their age: CC1, from 15 to 40 years; CC2, from 41 to 60 years; and CC3, from 61 to 85 years. RESULTS Twenty-one patients (26%) were male, while 59 (74%) were female. In the group CC1, intestinal metaplasia was present in 85.71% of the 21 patients studied; in CC2, in 79.41% of 34 patients; and in CC3, in 56.00% of 25 patients. These differences presented statistical significance (p = 0.04542). CONCLUSION Intestinal metaplasia is extremely frequent in gallbladders with inflammation and lithiasis, especially in younger patients.
