A complete R0 resection is the standard treatment in patients with gallbladder cancer and the only potentially definitive curative therapy. Major hepatectomy, including right or extended right hepatectomy with extrahepatic bile duct resection, would be an option in patients with locally advanced gallbladder cancer, while morbidity and mortality rate are still high. Herein, we report a case of a...
Aim To assess how laparoscopy has altered the presentation of patients with gallbladder cancer and determine whether radical resection in is beneficial. Method 47 underwent surgery because suspected cancer. Cancer was found incidentally 29 (61.7 %) during routine laparoscopic cholecystectomy using frozen biopsy. Gallbladder had been diagnosed preoperatively other 18 (38.3 %). Results Patients w...
PSCA and Oct-4 have been thought as markers of cancer stem cells. Although overexpression of PSCA and Oct-4 in cancer has been reported, little is known about the clinical and pathological significance with PSCA and Oct-4 expression in gallbladder adenocarcinoma. In this study, overexpression of PSCA and Oct-4 was detected in gallbladder adenocarcinoma (54.6% and 55.6%). Less expression of PSCA...
The gallbladder is an uncommon site of metastatic cancer. Although ultrasound can be regarded as a first line investigation for the detection of gallbladder lesions, differentiation between benign and malignant tumors usually requires resection. Real-time contrast enhanced ultrasound (CEUS) is a well-established technique for the classification of liver, pancreatic, and renal diseases (Weskott,...
OBJECTIVE Because thickening of the gallbladder wall is observed not only in patients with gallbladder cancer but also in those with benign diseases such as chronic cholecystitis and gallbladder adenomyosis, it is difficult to distinguish between benign and malignant gallbladder wall thickening by conventional techniques of diagnostic imaging such as computed tomography (CT), magnetic resonance...
AIM To describe contrast-enhanced ultrasound (CEUS) features and evaluate differential diagnosis value of CEUS and conventional ultrasound for patients with benign and malignant gallbladder lesions. METHODS This study included 105 gallbladder lesions. Before surgical resection and pathological examination, conventional ultrasound and CEUS were performed to examine for lesions. Then, all the l...
OBJECTIVE Although 5-fluorouracil (5-FU) is widely used in the treatment of various cancers, drug resistance remains a limitation for its anti-cancer activity. Mammalian target of rapamycin (mTOR) is deregulated in diverse human cancers, including gallbladder carcinoma and mTOR inhibitors show promising anti-cancer activities with proliferation inhibitory effects. This study aims to clarify the...
BACKGROUNDS Portal vein embolization (PVE) has been widely applied before extended hepatectomy; however, its clinical utility for patients with biliary cancer has not been fully addressed. METHODS Between 1991 and 2010, 494 patients with cholangiocarcinoma (n = 353) or gallbladder cancer (n = 141) underwent PVE before extended hepatectomy. PVE was performed by a transhepatic ipsilateral appro...
Gallbladder cancer is the most common malignant tumor of the biliary tract, and this condition has a rather dismal prognosis, with an extremely low five-year survival rate. To improve the outcome of unresectable and recurrent gallbladder cancer, it is necessary to develop new effective treatments and drugs. The purpose of the present study was to evaluate the effects of cordycepin on human gall...
There have been several studies on gallbladder carcinogenesis, and mutations of the KRAS, TP53, and CDKN2A genes have been reported in gallbladder carcinoma. The DBC1 gene (deleted in breast cancer 1) was initially cloned from region 8p21, which was homozygously deleted in breast cancer. DBC1 has been implicated in cancer cell proliferation and death. The functional role of DBC1 in normal cells...
