Immunohistochemical appraisal of epithelial mesenchymal transition type III in gall bladder cancer

Background: Epithelial-mesenchymal transition (EMT) is the heart of invasion. EMT associated with cancer progression and metastasis is known as type III EMT. Beta-catenin, E-cadherin, and MMP9 markers of EMT are routinely employed for diagnostic purposes. Aims: We employed these markers to study EMT by immunohistochemistry (IHC) in gall bladder cancer (GBC) with respect to depth of tumor invasion, clinical outcome, and disease-free survival. Settings and Design: This was a prospective case-control study. Material and Methods: Seventy gall bladders were included (50 GBC and 20 CC). After detailed histology, immunoexpression was studied in terms of percentage and strength of expression. Statistics Analysis Used: Expression was compared between CC and GBC by Student t test and analysis of variance. Kaplan–Meier was used for survival analysis, and the extent of agreement (“Kappa”) was calculated. Results and Conclusions: The age of incidence of GBC was 49.40 (+11.6) years with female predominance (F:M = 4:1). In 88% (44/50) of GBC, the fundus was involved. Moderately differentiated adenocarcinoma was most frequent [54%; 27/50]. Significant downregulation of E-cadherin (P = 0.022) and beta-catenin (P < 0.001) and upregulation in MMP9 (P < 0.001) were seen in GBC with respect to CC with significant association among them. MMP9 expression was significantly associated with higher tumor stage but with chemotherapeutic response. Our results display that epithelial-mesenchymal transition type III plays a role in GBC invasion. MMP9 overexpression and loss of membranous beta-catenin may be considered a marker for poor clinical outcomes and advanced disease.

Predictors of toxicity after neoadjuvant chemoradiotherapy for locally advanced gall bladder cancer

Background: The present study evaluated the correlation of hepatobiliary toxicity and radiation dose received in patients undergoing neoadjuvant chemoradiotherapy (NACRT) for locally advanced unresectable gall bladder cancers (LAGBC). Methods: Twenty-six patients with LAGBC, treated with NACRT (55–57 Gy/25 fractions/5 weeks and weekly gemcitabine 300 mg/m2) within a phase II study, were included. Whenever feasible, surgery was performed after NACRT. Acute and late hepatobiliary toxicity was recorded. Treatment scans were retrieved to delineate central porto-hepatobiliary system (CPHBS), resected liver surface, segment IV B and V, and duodenum. The doses received by these structures were recorded and correlated with toxicity. Results: Of 26 patients, 20 (77%) had partial or complete response and 12 (46%) had R0 resection. At the median follow-up of 38 months, overall survival was 38%. Eight (30%) patients had post-treatment toxicity, of which most common was biliary toxicity (30%). A correlation was observed between the biliary leak and V45Gy CPHBS >50 cm3 (P = 0.070). Higher toxicity was observed in those with metallic stents (P = 0.072). Conclusion: The incidence of the biliary leak was 46%. CPHBS dose was found to correlate with biliary leaks. Restricting V45Gy CPHBS <50 cm3 and using plastic stent may facilitate a reduction in hepatobiliary toxicity in patients undergoing NACRT and surgery.

A case report of primary hepatocellular carcinoma with gallbladder cancer / 西安交通大学学报(医学版)

ABSTRACT:Objective To a rare case of double primary cancer (hepatocellular carcinoma with gallbladder)to guide clinical application.Methods and Results We reported one case of primary hepatocellular carcinoma and gallbladder.A male patient,54 years old,had main complaints of intermittent right upper quadrant pain for 4 days. The abdominal CT of the local county hospital showed gallstones,gallbladder with liver infiltration.And then he went to the First Affiliated Hospital of Xi’an Jiaotong University for further treatment.Laboratory examination revealed:HBsAg(+),HBcAb(+),alpha-fetoprotein (AFP)> 60 500 ng/mL,carcinoembryonic antigen (CEA) 5.25 ng/mL.Abdominal CT showed hilar slightly stronger light echo groups:liver cancer or gallbladder cancer? Hepatic artery and portal vein CT imaging (CTA+CTV)examination showed the malignant tumor shadow in the inside of the left hepatic lobe huge,uneven thickening of the gallbladder wall,suspected liver disease with gallbladder infringement or gallbladder disease with liver infringement. With the preoperative preliminary consideration of primary liver cancer with infiltration of the gallbladder,we chose the operation as the resection of segment Ⅳ b and Ⅴ of the liver,cholecystectomy and T tube drainage.Pathological examination postoperative showed the bulky liver carcinoma grade Ⅲ and the poorly differentiated adenocarcinoma of gallbladder.A month later,abdominal CT showed the tumor spread intrahepatic,prompting the poor prognosis.Conclusion The two which are not continuous,which is the standard of double primary cancer,are not suitable for all double primary cancers.This case provides useful experience for future similar diagnosis and treatment of disease,and also helps us with timely and accurate identification of “metastatic”or “primary”,which is the key point for clinicians to give patients an effective treatment.

Profiles of gall bladder cancer reported in the hospital cancer registry of a Regional Cancer Center in the North-East India.

Background: The incidence of gall bladder cancer (GBC) is very high in this part of the world and there is little information on the descriptive epidemiology of GBC from our population. Methods: A retrospective study on the data set of hospital cancer registry was analyzed. The data set consisted of patient information registered during the period of January 2011 to December 2012. The cases included for the present study were histologically confirmed and radiologically diagnosed cases of GBC. All the cases were retrospectively analyzed for gender, age, urban-rural residences, religion of patients and their educational levels. Descriptive statistics was calculated and Chi square test was done to see the significance differences among categories. Results: A total of 837 cases of GBC were registered, F:M was 2.33, median age in females and males was 54 and 50 years respectively, majority of cases in both the genders were seen in 50-59 years of age, 81.1% patients were from rural areas and 18.8% from urban areas, Chi square on comparison with other cancers showed p<0.05, and there was no major religious and educational pattern of GBC seen in our population. Conclusion: In our population females are at high risk especially past 40 years of age and rural population with its varied environmental, lifestyles and infective agents should be investigated for possible risk factor in the causation of GBC.

The Experience of the Treatment of Scapular and Midback Pain in a Patient with Gall Bladder Cancer: A case report / 대한마취과학회지

Gall bladder cancer is a very rare disease but most common in the biliary system. It has a poor prognosis because it is usually detected at an advanced stage due to no specific symptoms. So sometimes all that is needed is a proper pain control. It is important to remember that newly developed pain area can be a referred pain due to a cancer. We present a patient with a gall bladder cancer who suffered from right scapular and paravertebral pain. For his pain relief, we tried celiac plexus block and his pain was dramatically relieved.

A Case of Acromegaly with Gall Bladder Cancer / 대한내분비학회지

Acromegaly is a systemic endocrine disorder due to an excessive release of growth hormone, which increases the serum levels of insulin-like growth factor-1(IGF-1). Elevated levels of these hormones are assumed to increase the incidence of malignant tumors in patients with acromegaly, due to by stimulating the growth and maturation of cells. In particular, IGF-1 is considered to be closely related with the development of colon polyps and colon cancers. Studies suggest that various malignant tumors, including thyroid cancer, brain tumor and renal cell carcinomas, are also more common in patients with acromegaly. Here, a case of gall bladder cancer in a patient with acromegaly, and the possible relationships between these two disorders, is reported.

External Beam Radiotherapy for Carcinoma of the Extrahepatic Biliary System / 대한치료방사선과학회지

PURPOSE: To evaluate the effectiveness and tolerance of patients ofexternal beam radiotherapy ofr carcinoma of the extrahepatic biliary system (EHBS) including gall bladder (GB) and extrahepatic bile ducts (EHBD) and to define the role of radiotherapy for these tumors. METHODS AND MATERIALS: We retrospectively analyzed the records of 43 patients with carcinoma of the EHBS treated with external beam radiotherapy at our institution between April, 1986 and July, 1994. Twenty three patients had GB cancers and remaining 20 patients did EHBD cancers. Of those 23 GB cancers, 2 had Stage II, 12 did Stage III and 9 did Stage IV disease, respectively. Male to female ratio was 11 to 12. Fifteen patients underwent radical surgery with curative intent and 8 patients did biopsy and bypass surgery alone. Postoperatively 16 patients were irradiated with 4500 cGy or higher doses and 4 patients with 3180 to 4140 cGy. Follow up periods ranged from 8 to 34 months. RESULTS: overall median survival time of patients with GB cancer was 11 months. Median survival time for patients with Stage III and IV disease were 14 months and 5 months, respectively. Corresponding two year survival rates were 36%(4/11) and 13%(1/8), respectively. Those who underwent surgery with curative intent showed significantly better survival at 12 months than those who underwent bypass surgery alone(67% vs 13%). None of the patients died of treatment related complications. Median survival time for entire group of 20 EHBD patients was 10 months. Median survivals of 10 Stage III and 7 Stage IV disease were 10 and 8 months, respectively. Two patients who underwent Whipple's procedure had 11 and 14 month survival and those treated with resection and drainage showed median survival of 10 month. CONCLUSION: Postoperative external beam radiotherapy for carcinoma of the extrahepatic billary system is well tolerated and might improve survival of patients. especially those with respectable lesions with microscopic or gross residual disease after surgery.

A Clinical Analysis on Primary Cancer of the Gall Bladder / 대한소화기내시경학회지

Carcinoma of Gall bladder remains a terminal illness in most patients despite improved diagnostic capabilities, better perioperative care and a more aggresive surgical approch based on improved knowledge of this tumors natural histiory. Overall 5-year survival rates remain below 5%. This failure to significantly improve patient oucome is largely due to late recognition of gall badder cancer. Authors experienced 21 cases of gall bladder cancer confirmed by operation at the Kwang Ju Christian hospital from march 1983 to March 1991, and the results obtained were summarized as follows.
