Cutaneous metastases from cholangiocarcinoma following percutaneous transhepatic biliary drainage: Case report and literature review
AbstractPercutaneous transhepatic biliary drainage (PTBD) is commonly used in the management of cholangiocarcioma. Major and minor complications of PTBD such as cholangitis, haemorrhage and catheter dislocation are well documented. A lesser reported complication are cutaneous metastases following PTBD for cholangiocarcinoma.We report a case of a 79 year old man who presented with right upper quadrant pain, jaundice and weight loss, with dilated intra-hepatic bile ducts on imaging. The cytology results from a sample taken during endoscopic retrograde cholangiopancreatography were highly suspicious of cholangiocarcioma. A PTBD was subsequently performed and bilateral metal biliary stents were placed without external drainage. Five months after the PTBD he was found to have a hard nodule under the PTBD puncture site. The nodule was excised and the histology confirmed a cholangiocarcinoma metastasis.A review of the literature identified twelve cases of cutaneous metastases from cholangiocarcinoma, following PTBD. In addition, tumour seeding along the catheter tract following PTBD, with metastatic deposits on the abdominal wall, peritoneoum, chest wall, pleural space, and liver parenchyma have also been reported.Health care professionals should be aware of this rare complication and offer appropriate management options to patients

Development of a Prognostic Model That Predicts Survival After Pancreaticoduodenectomy for Ampullary Cancer.
Objectives: The aims of this study were to i) identify independent predictors of survival following pancreaticoduodenectomy for ampullary cancer and ii) develop a prognostic model of survival.
Methods: Data were analysed retrospectively on 110 consecutive patients who underwent pancreaticoduodenectomy between 2002-2013. Subjects were categorised into 3 nodal sub-groups as per the recently proposed nodal sub-classification: N0 (node negative), N1 (1-2 metastatic nodes) or N2 (≥3 metastatic nodes). Clinicopathological features and overall survival were compared by Kaplan Meier and Cox regression analyses.
Results: The overall 1-, 3- and 5-year survival rates were 79.8%, 42.2% and 34.9% respectively. The overall 1-, 3- and 5-year survival rates for the N0 group were 85.2%, 71.9% and 67.4% respectively. The 1-,3-,5-year survival rates for the N1 and N2 subgroups were 84.6%, 58.4%, 56.4% and 80.2%, 38.8% and 8.0% respectively (log rank, p<0.0001). After performing a multivariate Cox regression analysis vascular invasion and lymph node ratio were the only independent predictors of survival. Hence a prediction model of survival was constructed based on those 2 variables.
Conclusion: Using data from a carefully selected cohort of patients we created a pilot prognostic model of post-resectional survival. The proposed model may help clinicians to guide treatments in the adjuvant setting.Mr Siong S.

Human primary liver cancer–derived organoid cultures for disease modeling and drug screening
Human liver cancer research currently lacks in vitro models that can faithfully recapitulate the pathophysiology of the original tumor. We recently described a novel, near-physiological organoid culture system, wherein primary human healthy liver cells form long-term expanding organoids that retain liver tissue function and genetic stability. Here we extend this culture system to the propagation of primary liver cancer (PLC) organoids from three of the most common PLC subtypes: hepatocellular carcinoma (HCC), cholangiocarcinoma (CC) and combined HCC/CC (CHC) tumors. PLC-derived organoid cultures preserve the histological architecture, gene expression and genomic landscape of the original tumor, allowing for discrimination between different tumor tissues and subtypes, even after long-term expansion in culture in the same medium conditions. Xenograft studies demonstrate that the tumorogenic potential, histological features and metastatic properties of PLC-derived organoids are preserved in vivo. PLC-derived organoids are amenable for biomarker identification and drug-screening testing and led to the identification of the ERK inhibitor SCH772984 as a potential therapeutic agent for primary liver cancer. We thus demonstrate the wide-ranging biomedical utilities of PLC-derived organoid models in furthering the understanding of liver cancer biology and in developing personalized-medicine approaches for the disease.M.H. is a Wellcome Trust Sir Henry Dale Fellow and is jointly funded by the Wellcome Trust and the Royal Society (104151/Z/14/Z).

Combined transplantation of the heart, lung, and liver.
Combined transplantation of the heart, lung, and liver may be indicated in patients with either end-stage respiratory failure complicated by advanced liver disease or end-stage liver failure complicated by advanced lung disease. A retrospective review of nine patients who underwent combined heart-lung-liver transplantation in Cambridge (1986-99) was carried out. The 1-year and 5-year actuarial survival was 56% and 42%, respectively. Combined heart-lung-liver transplantation is a feasible option for a few patients and has a 5-year survival similar to heart-lung transplantation but with a lower incidence of acute and chronic rejection

Primary amyloidosis presenting as cholestatic jaundice
This case report describes a rare but fatal presentation of amyloidosis. Multiple organs and systems can be affected by the condition. Cholestatic jaundice is a infrequent manifestation of amyloidosis. An 80-year-old patient died within a month after onset of jaundice as a result of irreversible damage caused by deposition of amyloid. The relatively short period of time did not allow a tissue sample to be obtained from the patient and the final diagnosis was made postmortem
