Multifocal mucus secreting papillary adenocarcinoma of the bile duct causing obstructive jaundice

Khan TF, Sherazi ZA, Alias NA, Mahmood Z

Ann Acad Med Singap, 1993 Mar;22(2):251-3.
PMID: 8363342

We present a 64-year-old Malay lady who had undergone a choledochoduodenostomy (CDD) two years ago for obstructive jaundice. She was admitted with jaundice and underwent ultrasonography, percutaneous transhepatic cholangiography (PTC), endoscopic retrograde cholangio pancreatography (ERCP) and computed tomographic (CT) scanning of the liver and biliary tree. All the investigations confirmed a type IVa choledochal cyst. At operation, the grossly dilated biliary system was packed with a thick mucoid material and the mucosa of the bile ducts was visibly abnormal with scattered nodules. This mucoid material had caused occlusion of the entire biliary tree resulting in obstructive jaundice. To the best of our knowledge, this is probably the first report of obstructive jaundice caused by thick mucus. The peculiar management problems of this case and the risk of malignant change in choledochal cysts are discussed.

PMID: 22582548 MyJurnal

Cholangiocarcinoma (CCA) is a rare biliary tract epithelial malignancy. We described the clinical features of CCA patients in our institution. A 10-year retrospective study of patients with cholangiocarcinoma in University Malaya Medical Centre was conducted. Clinical data and outcomes in relation to the three anatomical groups of CCA were collected and analysed. Of the 69 patients that were included 55% were male. Mean age was 61 years. Twelve (17%) had intrahepatic, 38 (55%) perihilar and 19 (28%) distal tumour. Mean age (p=0.043), median duration of symptoms (p=0.011), jaundice (p<0.001), total bilirubin level (p=0.003), INR (p=0.005) and mean tumour size (p=0.048) were significantly related to the site of tumour. Only 12 patients had curative resection with seven R0 resections. Cholangiocarcinoma is increasingly diagnosed in our population. Despite that, the diagnosis is still often late. Age, jaundice and tumour size may predict anatomical location of CCA.

Fulltext Choledochal cyst and cholangiocarcinoma

Yeoh NT, Somasundaram K, Alhady SF, Paramsothy M

Med J Malaysia, 1986 Dec;41(4):365-9.
PMID: 2823084

Carcinoma of the biliary tract is a rare complication of choledochal cysts. Furthermore, the greater predisposition of the cyst wall to neoplastic change has been cited as additional justification for cyst excision rather than on-site internal drainage as the primary choice of operation. The report concerns a patient who developed cholangiocarcinoma despite excision of a choledochal cyst and presented with symptoms of biliary obstruction within one year of the operation. Although this is a rare complication, the need for careful long-term follow-up is supported by this observation.

Intrahepatic cholangiocarcinoma and portal hypertension developing in a patient with multicystic biliary microhamartomas

Sugawara T, Shindoh J, Hoshi D, Hashimoto M

Malays J Pathol, 2018 Dec;40(3):331-335.
PMID: 30580365

INTRODUCTION: We report a case of intrahepatic cholangiocarcinoma and portal hypertension developing in a liver with biliary microhamartomas (von Meyenburg's complex).
CASE REPORT: The patient was a 55-year-old man who had a past medical history of diffuse multiple liver abscesses. During follow-up examination, a hypovascular nodule measuring 2.1 cm in diameter was incidentally found in segment 8 of the liver. Surgical resection was performed based on a suspected diagnosis of hepatocellular carcinoma. A gastrofiberscopy examination detected characteristic findings of portal hypertensive gastropathy. During the laparotomy, multiple tiny cystic lesions were observed in a diffuse pattern across the liver surface. The liver parenchyma was slightly fibrotic and haemorrhagic. A histopathological examination revealed intrahepatic cholangiocarcinoma with vascular invasions in von Meyenburg's complex. Multiple biliary adenomas were also observed among the biliary microhamartomas adjacent to the main tumour, suggesting that the malignant transformation of the biliary adenomas might have been responsible for the development of the intrahepatic cholangiocarcinoma. The histopathologic examination also revealed sinusoidal dilation and abnormal spacing of the portal tracts and central veins as evidence of portal hypertension.

PMID: 24377514

Gallstone disease is a major surgical problem in many populations; it is probably related to diet, especially excessive consumption of meat. The objective of this study was to determine the chemical composition of gallstones and their association with neoplastic changes including cholangiocarcinomas in cholecystectomised patients. The chemical composition of gallstones from 40 patients (8 males and 32 females) was analyzed. This is a prospective study performed in Baquba teaching hospital in the period from 1/10/2012 to 1/1/2013 in which we collected the gallstones for the patients who underwent cholecystectomy, whether open or laparoscopic. The stones were classified according to their chemical composition as a mixed stones (MS), and examined using a stone analysis set (chemical qualitative method) for calcium, magnesium, phosphate, uric acid and oxalate which was used reagent for qualitative determination of main individual components of stones. The results of this study showed the highest incidence of gallstones in the age group 40-49 was 13 cases followed by 11, 8 and 4 cases for age groups 30-39, 50-59, 20-29 and 60 and above, respectively. The chemical analysis showed the majority of gallstones were mixed, 38 containing calcium followed by 37 cases with uric acid, 28 with magnesium, and 25 and 22 stones with oxalate and phosphate, respectively. Microscopically, we confirmed neoplastic changes (17.5%) as cholangiocarcinomas (CCCs) (7.55%) and dysplastic cells of carcinoma in situ in 4 (10%), 31 (77.5%) cases were chronic cholecystitis and 2 (5%) cases were acute cholecystitis with empyema out of bile duct disorders patients. In conclusion, majority of cases had mixed gallstones that involved five and four of inorganic chemicals of calcium, magnesium and phosphate, the highest incidence of gallstones in age group 40-49 years old was 13 cases, and neoplastic changes were confirmed (17.5%) including CCCs, (7.5%) and dysplastic cells of carcinoma in situ (10%), while 31 (77.5%) cases were chronic cholecystitis.

Khan TF, Zahari A, Sherazi ZA, Visvanathan R

Singapore Med J, 1993 Oct;34(5):462-3.
PMID: 8153702

This is a report of a 57-year-old Malay lady who presented with recurrent episodes of cholangitis and septicaemia. A dilated biliary tree caused by a stenosing periampullary tumour was found to contain adult round worms. A pancreatico-duodenectomy was performed following biliary decompression. Ascarid worms are a rare cause of cholangitis in malignant biliary obstruction.

Fulltext Probable hepatic tuberculosis masquerading as Klatskin tumour in an immunocompetent patient

Hanafiah M, Alhabshi SM, Bag T, Low SF

BMJ Case Rep, 2013;2013.
PMID: 24343799 DOI: 10.1136/bcr-2013-010262

A 55-year-old immunocompetent woman was presented with features of obstructive jaundice and a clinicoradiological picture suggestive of a hilar cholangiocarcinoma (Klatskin tumour). However, caseating granulomatous lesion associated with miliary nodules were revealed intraoperatively. The lesion responded to standard antituberculous therapy. This unusual presentation highlights the considerable diagnostic challenge in such case.

Primary biliary cirrhosis and auto immune hepatitis overlap syndrome mimicking cholangiocarcinoma

Adel A, Zamri Z, Azlanuddin A, Bong JJ

Clin Ter, 2013;164(6):e493-5.
PMID: 24424229 DOI: 10.7417/CT.2013.1643

Primary Biliary Cirrhosis (PBC) and Auto Immune Hepatitis (AIH) are autoimmune diseases of the liver which highlighted with slow destructive process of intra hepatic small bile ducts. As a result of these damages cholestasis and over the time tissue damage will happen, which leads to scarring, fibrosis and finally cirrhosis. Some patients may present with clinical and biochemical features of both conditions, which is called "Overlap syndrome". Here we are reporting a case of PBC-AIH overlap syndrome that primarily diagnosed as gallbladder carcinoma and went under operation and finally histological examination revealed to be PBC.

Fulltext Biliary ascariasis and extrahepatic cholangiocarcinoma: a report of two cases

Lim KG, Sellaiah SP

Singapore Med J, 1994 Aug;35(4):400-2.
PMID: 7899902

We report two cases of rural Malay women in Perak, Malaysia, with extrahepatic cholangiocarcinoma and coexistent biliary ascariasis. In both cases, the narrowed bile duct may have resulted in inability of the migratory nematode to return to the gastrointestinal tract. It may be reasonable, also, to postulate that chronic biliary tract infestation by Ascaris lumbricoides may have contributed to the development of cholangiocarcinoma; a situation similar to that observed in liver fluke infestation.

Fulltext Blood Metabolic Signatures of Body Mass Index: A Targeted Metabolomics Study in the EPIC Cohort

Carayol M, Leitzmann MF, Ferrari P, Zamora-Ros R, Achaintre D, Stepien M, et al.

J Proteome Res, 2017 Sep 01;16(9):3137-3146.
PMID: 28758405 DOI: 10.1021/acs.jproteome.6b01062

Metabolomics is now widely used to characterize metabolic phenotypes associated with lifestyle risk factors such as obesity. The objective of the present study was to explore the associations of body mass index (BMI) with 145 metabolites measured in blood samples in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Metabolites were measured in blood from 392 men from the Oxford (UK) cohort (EPIC-Oxford) and in 327 control subjects who were part of a nested case-control study on hepatobiliary carcinomas (EPIC-Hepatobiliary). Measured metabolites included amino acids, acylcarnitines, hexoses, biogenic amines, phosphatidylcholines, and sphingomyelins. Linear regression models controlled for potential confounders and multiple testing were run to evaluate the associations of metabolite concentrations with BMI. 40 and 45 individual metabolites showed significant differences according to BMI variations, in the EPIC-Oxford and EPIC-Hepatobiliary subcohorts, respectively. Twenty two individual metabolites (kynurenine, one sphingomyelin, glutamate and 19 phosphatidylcholines) were associated with BMI in both subcohorts. The present findings provide additional knowledge on blood metabolic signatures of BMI in European adults, which may help identify mechanisms mediating the relationship of BMI with obesity-related diseases.

Fulltext The utility of hepatocyte paraffin 1 antibody in the immunohistological distinction of hepatocellular carcinoma from cholangiocarcinoma and metastatic carcinoma

Shiran MS, Isa MR, Mohd Sidik S, Rampal L, Hairuszah I, Sabariah AR

PMID: 18376797 MyJurnal

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and its diagnosis on routine stains is usually straightforward, except in some cases where there may be difficulty in distinguishing HCCs from metastatic carcinomas (MC) and cholangiocarcinomas (CC). Hepatocyte Paraffin 1 antibody (Hep Par 1) is a new monoclonal antibody which reacts with normal and neoplastic hepatocytes, and this study aims to determine its specificity and sensitivity in distinguishing hepatocellular carcinoma (HCC) from cholangiocarcinoma (CC) and metastatic carcinomas (MC). Hep Par 1 antibody was applied to 28 cases of HCC, 22 cases of MC from varying sites and 8 CCs, and produced a strong, diffuse, granular, cytoplasmic staining of all benign hepatocytes. 23 out of 28 cases of HCC showed heterogeneously positive staining for Hep Par 1 irrespective of their degree of differentiation, while 2 out of 8 cases of cholangiocarcinoma were positive for Hep Par 1, and all 22 cases of metastatic carcinoma were negative. The sensitivity and specificity of Hep Par 1 for HCC was 82.1% and 93.3% respectively; whereby the antibody was noted to show occasional false positivity in cases of cholangiocarcinoma and non-neoplastic bowel mucosa, while its variable staining in HCC produced false negative results in some small biopsies. Thus, Hep Par 1 should be used in a panel with other antibodies to obtain useful information in distinguishing HCC from CC and MC.

Prospective association of liver function biomarkers with development of hepatobiliary cancers

Stepien M, Fedirko V, Duarte-Salles T, Ferrari P, Freisling H, Trepo E, et al.

Cancer Epidemiol, 2016 Feb;40:179-87.
PMID: 26773278 DOI: 10.1016/j.canep.2016.01.002

INTRODUCTION: Serum liver biomarkers (gamma-glutamyl transferase, GGT; alanine aminotransferase, ALT; aspartate aminotransferase, AST; alkaline phosphatase, ALP; total bilirubin) are used as indicators of liver disease, but there is currently little data on their prospective association with risk of hepatobiliary cancers.
METHODS: A nested-case control study was conducted within the prospective EPIC cohort (>520,000 participants, 10 European countries). After a mean 7.5 mean years of follow-up, 121 hepatocellular carcinoma (HCC), 34 intrahepatic bile duct (IHBC) and 131 gallbladder and biliary tract (GBTC) cases were identified and matched to 2 controls each. Circulating biomarkers were measured in serum taken at recruitment into the cohort, prior to cancer diagnosis. Multivariable adjusted conditional logistic regression was used to calculate odds ratios and 95% confidence intervals (OR; 95%CI).
RESULTS: In multivariable models, 1SD increase of each log-transformed biomarker was positively associated with HCC risk (OR(GGT)=4.23, 95%CI:2.72-6.59; OR(ALP)=3.43, 95%CI:2.31-5.10;OR(AST)=3.00, 95%CI:2.04-4.42; OR(ALT)=2.69, 95%CI:1.89-3.84; OR(Bilirubin)=2.25, 95%CI:1.58-3.20). Each liver enzyme (OR(GGT)=4.98; 95%CI:1.75-14.17; OR(AST)=3.10, 95%CI:1.04-9.30; OR(ALT)=2.86, 95%CI:1.26-6.48, OR(ALP)=2.31, 95%CI:1.10-4.86) but not bilirubin (OR(Bilirubin)=1.46,95%CI:0.85-2.51) showed a significant association with IHBC. Only ALP was significantly associated with GBTC risk (OR(ALP)=1.59, 95%CI:1.20-2.09).
CONCLUSION: This study shows positive associations between circulating liver biomarkers in sera collected prior to cancer diagnoses and the risks of developing HCC or IHBC, but not GBTC.

Fulltext Alteration of amino acid and biogenic amine metabolism in hepatobiliary cancers: Findings from a prospective cohort study

Stepien M, Duarte-Salles T, Fedirko V, Floegel A, Barupal DK, Rinaldi S, et al.

Int J Cancer, 2016 Jan 15;138(2):348-60.
PMID: 26238458 DOI: 10.1002/ijc.29718

Perturbations in levels of amino acids (AA) and their derivatives are observed in hepatocellular carcinoma (HCC). Yet, it is unclear whether these alterations precede or are a consequence of the disease, nor whether they pertain to anatomically related cancers of the intrahepatic bile duct (IHBC), and gallbladder and extrahepatic biliary tract (GBTC). Circulating standard AA, biogenic amines and hexoses were measured (Biocrates AbsoluteIDQ-p180Kit) in a case-control study nested within a large prospective cohort (147 HCC, 43 IHBC and 134 GBTC cases). Liver function and hepatitis status biomarkers were determined separately. Multivariable conditional logistic regression was used to calculate odds ratios and 95% confidence intervals (OR; 95%CI) for log-transformed standardised (mean = 0, SD = 1) serum metabolite levels and relevant ratios in relation to HCC, IHBC or GBTC risk. Fourteen metabolites were significantly associated with HCC risk, of which seven metabolites and four ratios were the strongest predictors in continuous models. Leucine, lysine, glutamine and the ratio of branched chain to aromatic AA (Fischer's ratio) were inversely, while phenylalanine, tyrosine and their ratio, glutamate, glutamate/glutamine ratio, kynurenine and its ratio to tryptophan were positively associated with HCC risk. Confounding by hepatitis status and liver enzyme levels was observed. For the other cancers no significant associations were observed. In conclusion, imbalances of specific AA and biogenic amines may be involved in HCC development.

MyJurnal

A 7-year-old, intact female Domestic Shorthair cat was referred to University Veterinary Hospital (UVH), UPM for diagnostic workup of a hepatomegaly observed on abdominal radiographs. Physical examination revealed no significant findings except for a distended abdomen. Hematology and serum biochemistry findings included a regenerative anaemia, left shift neutrophilia and a 10-fold elevation in gamma-glutamyltranspeptidase (GGT). Abdominal ultrasound revealed heterechoic liver lobes with irregular margins and presence of nodular and cyst-like structures predominantly affecting the left lobes. A mild ascites was also noted. A fine needle aspiration of the liver was performed and cytology results confirmed a cholangiocarcinoma. Generally, the outcome for cholagiocarcinoma is poor and there is limited information regarding the prognosis for patients with cholangiocarcinoma following chemotherapy or surgery.
