Surgical management of perihilar cholangiocarcinoma: a Khon Kaen experience
ABSTRACT Cholangiocarcinoma is the most common cancer in the northeast of Thailand. Most of the patients present when the disease is in an advanced stage. Improvement of preoperative diagnoses and surgical techniques provide more satisfactory results. Herein we reviewed our 30-year experience in management of perihilar cholangiocarcinoma in Khon Kaen northeast Thailand. Between 1982 and 2012 we reviewed four specific studies of perihilar cholangiocarcinoma in Srinagarind Hospital, Khon Kaen, Thailand. The first study focused on advanced surgical pathology and palliative surgery, which were used to treat obstructive jaundice cholangiocarcinoma patients. Long-term survival in this study was rare with a one-year survival of just 15%. The second study was conducted on 30 consecutive cases of perihilar cholangiocarcinoma who presented with obstructive jaundice without preoperative biliary drainage. All the patients underwent major liver resection with bilio-enteric reconstruction. Perioperative mortality was 6.7% without a 5-year survival. The third study aimed to analyze the survival rates and factors affecting survival in extrahepatic CCA patients following surgical treatment at Srinagarind Hospital and concluded that resection margins are an important prognostic factor. The last study objective was the analysis of curative surgical attempt in 99 consecutive perihilar cholangiocarcinoma and results showed that R0 resection could improve long-term survival. We evaluated four studies of perihilar cholangiocarcinoma in Srinagarind Hospital, Khon Kaen, Thailand from 1982-2012. Viewed chronologically there has been a progressive improvement of diagnosis and surgical treatment during the past 30 years. Despite these advances the 5-year survival rate remains unsatisfactorily low. Future improvement of patient selection and surgical techniques can lead to a greater survival rate for patients.

ABSTRACT: The epithelial-mesenchymal transition (EMT) process strongly contributes to cancer metastasis. This study was to investigate the alteration of EMT-related proteins (ZEB1, ZEB2 and S100A4) in cholangiocarcinoma (CCA) tissues. The effect of tumor necrosis factor-α (TNF-α) on the expression of those molecules in CCA cells was investigated.Journal of Hepato-Biliary-Pancreatic Sciences 09/2014; 21(9). DOI:10.1002/jhbp.125
