ABSTRACT

Background: Gallbladder (GB) malignancy is the commonest biliary tract carcinoma. It ranks fifth among the malignancies of the gastrointestinal tract and in all encompasses about 1-3% of all malignancies. Its peak occurrence is in the 5th decade or older with a female predilection. The most cases of GB malignancy are seen along the Ganga river delta region in India. The median survival rate in GB malignancy is approximately 6 months. Methods: A cross-sectional observational study was conducted in the Department of Radiology, Narayan Medical College and Hospital Sasaram over a period of 12 months from August 2022 to September 2023. A total of 40 patients were included on the basis of signs and symptoms of gallbladder carcinoma and underwent USG and CT scan for preoperative radiological diagnosis, following operation all the resected specimens were sent for histopathological evaluation. The diagnostic accuracies of USG and CT scan were then compared against histopathological diagnosis by using Kappa statistics. Results: In the present study, the mean age of the patients was 60 (range: 40-80 years) with female preponderance. About 40% of the gall-bladder were contracted and reduced in size and 35% large and distended on USG examination, while 45% of the gall-bladder were contracted and reduced in size and 37.5% distended and large on CT examination. Approximately 37.5% had irregularly thickened wall and 25% diffusely thickened wall on USG and 25% of gallbladder wall were diffusely thickened and 45% irregularly thickened on CT scan. The present study showed hepatic parenchymal invasion to be 25% on USG and 37.5% on CT scan. The sensitivity and specificity of USG in diagnosing GB carcinoma were 94.2% and 71.4% respectively. Similarly, the sensitivity and specificity of CT scan in detecting GB carcinoma were 97.1% and 83.3% respectively. The test of agreement (Kappa test) revealed an almost 90% agreement between the two procedures meaning that the two diagnostic modalities are almost comparable in diagnosing gall bladder carcinoma. Conclusions: As the histopathological diagnosis of the present study correlated well with USG and CT scan findings in the diagnosis of gallbladder carcinoma; it can be concluded that both USG and CT scan are useful imaging modalities for diagnosing this disease. However, CT scan is more sensitive and specific in predicting gall bladder carcinoma as compared to USG.

ABSTRACT

【Objective】 To construct the prediction model of perineural invasion (PNI) in gallbladder carcinoma (GBC) based on preoperative enhanced CT image features and evaluate its prediction efficiency. 【Methods】 The clinical, imaging and pathological data of 180 GBC patients undergoing radical operation were retrospectively analyzed. They were divided into positive and negative groups according to the presence or absence of PNI. Preoperative enhanced CT imaging features (including presence of gallstones, imaging hepatic invasion, vascular invasion, T-stage, and hilar or retroperitoneal lymph node metastases) were evaluated by two radiologists. Independent sample t-test, Mann Whitney U test, and χ2 test were used to compare the correlation between CT signs and PNI. Logistics regression analysis was used to screen independent risk factors and establish the prediction model formula. ROC curve was used to evaluate the prediction efficiency of the prediction model and the corresponding area under the curve (AUC) was calculated. Hosmer-Lemeshow goodness of fit test was used to verify the prediction model. 【Results】 Unifactorial analysis showed that CA199, CA125, imaging hepatic invasion, vascular invasion (hepatic artery or portal vein), T-stage, and hilar or retroperitoneal lymph node metastasis were correlated with nerve invasion (P<0.05). Logistics multi-factor analysis results showed that CA199, imaging vascular invasion (hepatic artery or portal vein), and imaging T stage were independent risk factors for PNI. Based on the above independent risk factors, a prediction model formula was established and ROC curve was drawn, with an AUC of 0.807 (95% CI: 0.734~0.879), sensitivity of 0.792, specificity of 0.697, and the chi-square value of Hosmer-Lemeshow goodness of fit test of 0.594 (P=0.997), indicating that the predicted value of the model was close to the actual value. 【Conclusion】 Combining CA199, imaging vascular invasion, T-stage, and other preoperative clinically-enhanced CT features to establish a prediction model can effectively predict postoperative PNI of GBC.

ABSTRACT

Background: Gallbladder carcinoma (GBC) although rare is most frequent malignant neoplasm of biliary tract system and sixth most common malignancy of digestive tract. GBC is more common in females and there are studies which show expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 neu (HER2/neu) in GBC suggesting possible molecules for targeted therapy, but results are inconsistent. Aims and Objectives: The aim of this study was to find out expression of ER, PR, and HER2/neu in GBC in North Indian population and their possible association with clinicopathological features. Materials and Methods: A total 59 resected cases of GBC diagnosed by histopathological examination were included in the study. Expression of ER, PR, and HER2/neu was accessed by immunohistochemistry method and correlated with various clinicopathological features. Results: ER expression was absent in all GBC cases. PR expression was present in only one case. Positive expression of HER2/neu was present in 13 (22%) cases, in which 12 cases were of conventional adenocarcinoma and one case was of papillary adenocarcinoma. Well and moderately differentiated tumor had significantly higher HER2/neu expression as compared to poorly differentiated tumors (P = 0.001). Pre-obese patients had significantly higher HER2/neu expression as compared to non-obese patients (P = 0.008). Conclusion: In our study, there was no expression of estrogen and PR in GBC in North Indian population. Although small in number, there is a subset of patients who overexpress HER2/neu receptor that may benefit from targeted therapy.

ABSTRACT

Objective:To identify the independent risk factors affecting the prognosis of gallbladder cancer after radical resection, and to develop and validate the nomogram of predictive model.Methods:The clinical data of 147 patients with gallbladder cancer treated in the First Affiliated Hospital of Xinjiang Medical University from January 2012 to January 2022 were retrospectively analyzed, including 53 males and 94 females, aged (61.45±10.76) years old. The patients were followed up by outpatient or telephone review. The Kaplan-Meier method and log-rank test were used for survival analysis. The variables of P<0.1 in univariate analysis were included in the minimum absolute convergence and selection operator (LASSO) regression model, and the predictive factors affecting the prognosis of gallbladder cancer were screened. The predictive model was established by multivariate Cox regression analysis, and a nanogram was constructed based on the multivariate Cox regression model. The discrimination of the model was evaluated by consistency index (C index), time-dependent C index curve, receiver operating characteristic curve and area under the curve (AUC). 500 times of Bootstrap sampling were conducted for the calibration of nomogram. Results:The median survival of patients with gallbladder cancer was 22.15 months, and the 1-, 2- and 3-year cumulative survival rates were 65.99%, 46.02% and 35.73%, respectively. LASSO regression analysis showed that age, abdominal pain, degree of differentiation, T stage, N stage, serum levels of CA-199 and total bilirubin were predictive factors affecting the prognosis of gallbladder cancer (all P<0.05). The prognosis prediction model was established by multivariate Cox regression analysis. The C-index was 0.856 (95% CI: 0.823-0.887). The AUC values for 1-year and 3-year survival probabilities are 0.939 and 0.944, respectively. The calibration chart indicates that this model has a good accuracy. The decision curve analysis confirmed that the net benefit of this model is significantly higher than two extreme situations, indicating its clinical applicability and patients’ benefits. Conclusion:The nomogram for postoperative prognosis of gallbladder cancer based on age, abdominal pain, degree of differentiation, T stage, N stage, serum levels of total bilirubin and CA-199 has a high accuracy, which might affect the treatment decision-making of patients with gallbladder cancer.

ABSTRACT

Gallbladder carcinoma is a tumor with poor prognosis and lack of effective comprehensive treatment. At present, surgical resection is still the main treatment for gallbladder carcinoma. Precise evaluation and adequate preparation before surgery, and safe, effective, standar-dized resection are the key points to successful treatment of gallbladder carcinoma. In clinic, there has been a growing appreciation of the prevention and reasonable treatment of incidental gallbladder carcinoma. Neoadjuvant and conversion therapy give full play to the effects of chemotherapy, targeted therapy, and immunotherapy agents on tumor cells, which can achieve the goal of downstage or conversion of tumors before surgery, increasing the radical resection rate, and improving the prognosis of patients.

ABSTRACT

Cholecystic adenomyosis is a common benign lesion of the biliary system. Recently, cholecystic adenomyosis has been diagnosed to harbour an incidental gallbladder cancer (IGBC) on intraoperative or postoperative pathological examinations. In this article, we reviewed 586 patients who were treated at Zhongshan Hospital, Fudan University with a preoperative diagnosis of cholecystic adenomyosis, and found 5 patients with IGBC diagnosed by pathological examinations. We described the clinical characteristics, imaging features and pathological findings of these 5 cases. We further reviewed the relevant medical literatures to provide a comprehensive view on IGBC of adenomyosis origin.

ABSTRACT

Background and Aim: The etiology of extrahepatic biliary obstruction (EHBO) ranges from benign disorders to pancreaticobiliary malignancy. We studied the demographic, clinical, laboratory, and endoscopic features of young patients with EHBO undergoing Endoscopic retrograde cholangiopancreatography (ERCP). Methods: We retrospectively analyzed one-year data of ERCP procedures performed on adult patients under 40 years of age. The diagnosis was based on a clinical and radiological basis with histopathological confirmation. Results: A total of 180 patients were included with a mean(±SD) age of 33.4(±5.8, range: 15-40) years, and 67.8% being female. Benign (67.2%) findings included choledocholithiasis (57.8%), benign biliary stricture (9.44%, post cholecystectomy stricture 82.3%), and malignant (32.8%) causes were gallbladder carcinoma (24.4%), cholangiocarcinoma (4.4%), periampullary carcinoma (2.8%), pancreatic head carcinoma (1.1%). Clinical presentation included jaundice (66.1%), pain abdomen (59.4%), pruritis (26.1%), weight loss (19.4%), anorexia, fever, and cholangitis (24.44%). Mean bilirubin levels (16.9 ±6.8 vs 4.6 ±4.1 mg/dl) and alkaline phosphatase (1170 ± 260.7 vs 439.3 ± 362.7 IU/mL) were higher in malignant causes, in comparison to benign. Stone retrieval using balloon during ERCP was successful in 79% of cases. Large (>15 mm) or impacted stones or those with biliary stricture failed stone extraction. In gallbladder carcinoma, adequate endoscopic biliary drainage was achieved in 68% of patients. Endoscopic biliary drainage was achieved in 75%, 80%, and 50% cases of cholangiocarcinoma, periampullary carcinoma, and pancreatic head carcinoma, respectively. Conclusion: Choledocholithiasis and gallbladder carcinoma are the most common benign and malignant causes of EHBO in young patients. The successful endoscopic therapeutic intervention could be achieved in most patients.

ABSTRACT

The First Affiliated Hospital of Xi’an Jiaotong University has experienced more than 60 years’ history in the diagnosis and treatment of gallbladder carcinoma (GBC). From 1956 to 2018, 3 430 cases of GBC were treated, including 1941 cases of surgical treatment and 703 cases of radical resection. The data comparison between 1956-2008 and 2009-2018 revealed that the radical resection rate increased from 19.9% to 48.3%. The mean survival time after regional radical resection and extended radical resection was (23.1±15.4) and (17.5±16.2) months, respectively, from 2004 to 2008. Compared with those between 2013 and 2017, the mean survival time after regional radical resection and extended radical resection was (31.5±2.0) and (18.6±3.9) months, respectively, and the median survival time was 31.0 and 11.0 months, respectively. By comparing the GBC data longitudinally, the mode of diagnosis and treatment of GBC in our hospital has changed significantly in the past 10 years, which is mainly reflected in the change of GBC staging system, the progress of imaging diagnosis mode, the standardization of surgery and the development of adjuvant treatment. All of these have significantly improved the prognosis of GBC.

ABSTRACT

【Objective】 To investigate the effects of gallbladder cancer-associated fibroblasts (CAFs) on the migration of lymphatic endothelial cells (LECs) so as to elucidate the molecular mechanisms involved. 【Methods】 The CAFs and normal fibroblasts (NFs) were extracted by enzymatic digestion, and the supernatant (CM) of CAFs and NFs was collected. The levels of IL-6, IGFBP3 and other related cytokines were detected by semi-quantitative protein factor microarray and ELISA. The expressions of α-SMA (CAFs maker) and IGFBP3 in gallbladder cancer and para-cancer tissues were detected by immunohistochemistry, and the correlation of α-SMA and IGFBP3 expressions with clinicopathological characteristics were analyzed. LECs were cultured and divided into serum-free medium group (control group), CAF-CM co-culture group, NF-CM co-culture group, IGFBP3 group, and CAF-CM+IGFBP3 inhibitor (2-Deoxy-D-glucose, 2-DG) group according to different treatment. Transwell migration assays and wound healing assays were applied to analyze the migration ability of LECs under different treatment. The expressions of E-cadherin, N-cadherin and Vimentin were detected by Western blotting. 【Results】 Protein factor microarray and ELISA showed that the concentration of IGFBP3 in CAF-CM was significantly increased, and the expression of α-SMA was significantly related to lymph node metastasis, advanced TNM stage and expression of IGFBP3. IGFBP3 secreted from CAF-CM significantly promoted LECs migration, up-regulated the expression of N-cadherin and Vimentin, and down-regulated the expression of E-cadherin. Treatment with IGFBP3 inhibitor 2-DG could reverse the effect of CAF-CM on migration of LECs and related protein expressions. 【Conclusion】 Gallbladder CAFs promote the migration of LECs via releasing IGFBP3, which affects EMT transformation.

ABSTRACT

【Objective】 To explore the different expressions of TP53, P16 and K-ras in gallbladder high-grade intraepithelial neoplasia and early carcinoma, and establish their mutation random forest prediction model. 【Methods】 We retrospectively analyzed the clinicopathological data of 71 patients who underwent cholecystectomy at The First Affiliated Hospital of Xi’an Jiaotong University from January 2013 to December 2018, including 20 cases of chronic cholecystitis, 28 cases of gallbladder high-grade intraepithelial neoplasia, and 23 cases of early gallbladder carcinoma. The immunohistochemical SP method was conducted to detect the expressions of TP53, P16 and K-ras in the gallbladder pathological tissues; the correlation between the above genes and clinicopathological data was analyzed. A random forest prediction model of each gene mutation was established based on the clinicopathological data and gene expression. 【Results】 The positive expressions of TP53, P16 and K-ras were related to the gallbladder with cholecystolithiasis or polyps and gallbladder pathological tissue type. The positive rates of the three genes in the gallbladder polyps were significantly higher than those in the cholecystolithiasis group (P<0.05). The positive rates of the three genes in the latter two groups of gallbladder high-grade intraepithelial neoplasia and early gallbladder carcinoma were significantly higher than those in the chronic cholecystitis (P<0.05), while there was no statistical difference between the latter two groups (P>0.05). The mutations of TP53, P16 and K-ras had a certain correlation (χ2=6.285, 19.595, 4.070, r=0.298, 0.525, 0.239, P<0.05). TP53, P16 and K-ras mutation prediction models based on random forest had good accuracy (AUC=77.42%, 80.06%, 71.75%, accuracy=76.06%, 76.06%, 67.61%). 【Conclusion】 TP53, P16 and K-ras gene mutations promote the transformation of chronic cholecystitis to gallbladder carcinoma. The mutation prediction model based on random forest has a good accuracy, which can provide an important reference for carcinogenesis and early diagnosis of gallbladder carcinoma.

ABSTRACT

Context: Gallbladder carcinoma (GBCA) is the fifth most common types of gastrointestinal malignancy and is the most common malignancy of the biliary tract. Cholelithiasis, gallbladder polyps, porcelain gall, and choledochal cysts are common known associations with GBCA. Because of the better understanding of the etiopathogenesis, the traditional nihilistic attitude toward the prognosis has, over the years, given way to greater interest and hope for treating the disease. Long-term survival has been reported in patients with resectable lesions in the hands of expert hepatobiliary surgeons. Objective: This prospective observational study was conducted at a tertiary referral hospital of Eastern India on patients with the diagnosis of GBCA. The main objective was to assess the incidence of gallstones in patients with GBCA, and the relationship, if any, between the size and number of stones and GBCA in our patient cohort. Materials and Methods: This prospective observational study was conducted, over a period of 2 years, at a tertiary referral hospital of Eastern India which caters to patients from all the neighboring districts. A total of 54 patients with the diagnosis of GBCA were included in the study. Data on their demographic and clinical profile, the incidence of associated gallstones, their size (<3 or ≥3cm), and number (solitary or multiple) were collected. Known predisposing factors of GBCA, if any, in those presenting without stones were noted. Results: GBCA was found to afflict females 2.4 times as frequently as males. Patients, irrespective of their sex, were mostly in their sixth decade. Approximately three-fourth of the cases had associated cholelithiasis. The number of stones had no correlation with the disease. However, contrary to available published data, stones <3 cm were significantly more common in our study cohort. Conclusion: The results of this study reaffirm that cholelithiasis is a strong predisposing factor for GBCA and females with gallstones in their sixth decade, are more at risk. Although number of stones was not found to be an independent risk factor, patients with stones <3 cm (mostly multiple) were found to be more at risk in our study

ABSTRACT

Objective@#To discuss the rationality of stage pT3 in the AJCC 8th TNM criteria of gallbladder carcinoma.@*Methods@#A retrospective study was performed to analyze the clinical and pathological data of 88 patients with pT3 gallbladder carcinoma admitted to Department of Second Biliary Surgery of Eastern Hepatobiliary Surgery Hospital, affiliated to Naval Medical University from May 2013 to September 2018.pT3 stage tumors were divided into two groups: (1) pT3a stage: tumors had penetrated serosa but not directly invaded liver and/or an adjacent organ or structure; (2) pT3b stage: tumor penetrating serosa and directly invaded liver and/or an adjacent organ or structure. There were 45 patients with pT3a stage, including 15 males and 30 females, aged 36 to 80 years, with a median age of 59 years; 43 patients with pT3b, including 24 males and 19 females, aged 41 to 78 years old, median aged 63 years old.Patients with pT3a and pT3b were further divided into two groups respectively: radical resection group and extended radical resection group according to surgical radicalization. Independent sample t-test was used for comparison between two groups with normal distribution measurement data. Wilcoxon rank sum test was used between groups of non-normally distributed measurement data.The comparison of the count data was performed by χ2 test or Fisher exact probability method. Survival analysis was performed using Kaplan-Meier method, and survival rate was compared using Log-rank test.@*Results@#(1)Serum total bilirubin(15.6(90.3)mmol/L), albumin(40.2(4.8)mmol/L), and CA19-9(132.90(455.78)U/ml) levels in pT3b patients were higher than that in pT3a patients(10.2(6.8)mmol/L, 41.8(4.9)mmol/L, 14.35(36.27)U/ml), respectively(Z=-3.816, -1.966, -3.739, all P<0.05),postoperative complication rate in pT3b patients(24.4%) was higher than that in pT3a patients(8.9%)(P<0.05),postoperative hospital stay(12(7)days) and overall hospital stay((26±17)days) of pT3b patients were longer than that of pT3a patients((10±5) days and (19±7)days) (P<0.05). (2) The 1-, 3-, 5-year survival rates of pT3b and pT3a patients were 53%,22%,22% and 69%, 46%,38%,and the median survival time was 13 months and 26 months, respectively. The difference in survival rates between the two groups was statistically significant(χ2=5.117, P=0.024). (3)The 1-, 3-year survival rates of extended radical resection group(n=19) and radical resection group(n=24) in the pT3b stage were 73%, 36% and 28%, 7%, respectively.The survival time was 20 months and 9 months,respectively,and the difference in survival rates between the two groups was statistically significant(χ2=4.976, P=0.026).@*Conclusions@#pT3 gallbladder carcinoma could be further subdivided into pT3a stage and pT3b stage based on the TNM criteria of AJCC 8th gallbladder carcinoma. Extended radical resection for pT3b gallbladder carcinoma should be further considered after comprehensive assessment of the patient′s basic condition and surgical tolerance.

ABSTRACT

Objective@#To compare the efficacy of postoperative adjuvant radiotherapy and non-radiotherapy in patients with extrahepatic cholangiocarcinoma and gallbladder carcinoma by a meta-analysis.@*Methods@#The controlled clinical trials of postoperative adjuvant radiotherapy versus non-radiotherapy of extrahepatic cholangiocarcinoma and gallbladder carcinoma were searched from PubMed, EMbase, Cochrane Library, Wanfang database, CNKI, Chongqing VIP and CBM databases. The obtained data were analyzed using RevMan 5.3 and Stata 14.0 statistical software. The difference between two groups was estimated by calculating the odds ratio (OR) with 95% confidence interval (CI).@*Results@#A total of 20 controlled clinical trials involving 1258 extrahepatic cholangiocarcinoma and gallbladder carcinoma patients were included in this meta-analysis. The meta-analysis demonstrated that the 5-year survival rate in the adjuvant radiotherapy group was significantly higher than that in the non-radiotherapy group (OR=1.67, 95%CI: 1.29-2.18, P=0.001). The 5-year survival rates in those with lymph node positive disease (OR=7.44, 95%CI: 1.24-44.72, P=0.03) and positive margins disease (OR=3.43, 95%CI: 1.56-7.75, P=0.002) were significantly enhanced by postoperative adjuvant radiotherapy. The local recurrence rate in the adjuvant radiotherapy group was significantly lower than that in the non-radiotherapy group (OR=0.56, 95%CI: 0.39-0.80, P=0.01), whereas the distant metastasis rate did not significantly differ between two groups (OR=1.22, 95%CI: 0.86-1.73, P=0.27). The incidence rates of acute toxicity and chronic toxicity of grade ≥3 caused by radiotherapy were 0-11.9% and 0-21.7%, respectively.@*Conclusion@#Compared with non-radiotherapy, postoperative adjuvant radiotherapy is a safer and more effective postoperative treatment for extrahepatic cholangiocarcinoma and gallbladder carcinoma.

ABSTRACT

Objective To investigate the effects of the extent of regional lymph node dissection on the prognosis of patients with T4 gallbladder carcinoma.Methods The retrospective cohort study was conducted.The clinicopathological data of 64 patients with T4 gallbladder carcinoma who underwent radical cholecystectomy in the 4 medical centers between January 2013 and December 2016 were collected,including 31 in the Eastern Hepatobiliary Surgery Hospital of Naval Medical University,16 in the First Affiliated Hospital of Xi'an Jiaotong University,11 in the Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine and 6 in the Affiliated Hospital of North Sichuan Medical College.There were 27 males and 37 females,aged from 35 to 77 years,with a median age of 59 years.Sixty-four patients underwent radical cholecystectomy and regional lymph node dissection.According to the extent of intraoperative lymph node dissection,25 patients (13 in the Eastern Hepatobiliary Surgery Hospital of Naval Medical University,6 in the First Affiliated Hospital of Xi'an Jiaotong University,4 in the Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine and 2 in the Affiliated Hospital of North Sichuan Medical College) whose extent of lymph node dissection involved lymph nodes next to cystic duct,hepatoduodenal ligament,back of head of pancreas,next to common hepatic artery and celiac trunk were allocated into the extended dissection group,39 patients (18 in the Eastern Hepatobiliary Surgery Hospital of Naval Medical University,10 in the First Affiliated Hospital of Xi'an Jiaotong University,7 in the Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine and 4 in the Affiliated Hospital of North Sichuan Medical College) whose extent of lymph node dissection involved lymph nodes next to cystic duct and hepatoduodenal ligament were allocated into the control group.Observation indicators:(1) postoperative complications;(2) follow-up and survival situations.Follow-up using outpatient examination and telephone interview was performed to detect postoperative overall survival up to January 2018.Measurement data with normal distribution were represented as Mean±SD,and comparison between groups was evaluated with the independentsample t test.Count data were represented as absolute number or percentage,and comparison between groups was analyzed using the chi-square test and Fisher exact probability.The survival curve was drawn using the KaplanMeier method,and the comparison of survival rates was done by the Log-rank test.Results (1) Postoperative complications:64 patients with T4 gallbladder carcinoma underwent successful radical cholecystectomy and regional lymph node dissection,without intraoperative death.Twelve patients had different degrees of postoperative complications.Four of 7 patients undergoing extended radical cholecystectomy had postoperative complications.Twenty-five patients in the extended dissection group were cured by conservative treatment,including 4 with intraperitoneal infection and 2 with pancreatic leakage,with a complication incidence of 24.0% (6/25).Thirtynine patients in the control group were cured by conservative treatment,including 5 with intraperitoneal infection and 1 with gastric retention,with a complication incidence of 15.4% (6/39).There was no statistically significant difference in the complication incidence between the two groups (x2=0.284,P>0.05).(2) Follow-up and survival situations:64 patients were followed up for 1-60 months.The postoperative overall median survival time was l l months.The postoperative median survival time,1-,3-and 5-year cumulative survival rates were respectively 18 months,80%,16%,9% in the extended dissection group and 8 months,21%,4%,0 in the control group,with a statistically significant difference in the prognosis between the two groups (x2=14.744,P< 0.05).Conclusions On the premise of practiced surgical skill,extended regional lymph node dissection cannot increase incidence of surgical complication in patients with T4 gallbladder carcinoma after radical resection.Actively extending lymph node dissection up to near common hepatic artery,peri-celiac trunk and back of head of pancreas can improve long-term survival and prognosis.

ABSTRACT

Background: Carcinoma gallbladder is a major problem in India. In this retrospective study from the tertiary care centre of the north–east India, we aim to review the various Multidetector Computed Tomography (MDCT) imaging findings of gallbladder carcinoma. Methods: We retrospectively analysed MDCT findings in 65 biopsy proven cases of gallbladder carcinoma. After administration of oral contrast for bowel opacification, all patients were subjected to non–contrast scan of the upper abdomen followed by contrast enhanced study of the abdomen and pelvis in the portal venous phase. Results: Focal mass lesion arising from gallbladder was the predominant pattern of growth seen in 31(48%) patients followed by focal or asymmetric diffuse wall thickening in 28(43%) patients. Twelve (18%) patients had mass in gallbladder fossa replacing the gall bladder. Adjacent hepatic infiltration was seen in 48(74%) patients. Conclusion: Our study highlights the importance of MDCT for the diagnosis, characterisation and staging of gallbladder carcinoma.

ABSTRACT

Objective To analyze the clinical efficacy and toxic reaction of Tegafur,Gimeraciland Oteracil Potassium Capsule combined with Gemcitabine chemotherapy for patients with radical resection for advanced gallbladder carcinoma.Methods The clinical dataof 135 patients with advanced gallbladder cancer who were admitted to the 1 st Affiliated Hospital of Zhengzhou University and supported after the gastrectomy by the pathology from June 2007 to June 2012 were retrospectively analyzed.All patients were divided into three groups by different therapeutic regimens,operation groups (Radical resection or Extended radical resection of gallbladder carcinoma) with 47 cases,chemotherapy A group (Tegafur,Gimeracil and Oteracil Potassium Capsule combined with Gemcitabine chemotherapy after Radical resection or Extended radical resection of gallbladder carcinoma) with 52 cases,and chemotherapy B group (5-Fluorouracil combined with Oxaliplatin chemotherapy after Radical resection or Extended radical resection of gallbladder carcinoma) with 36 cases.We collected the dates of all patients with the median survival time and the 1,3 and 5-year survival rate after operation,and counted the rate of major toxic reaction after chemotherapy.Results There were no significant differences in the general date of three groups (sex,age,tumor size,CA19-9,CA125,TNM stages,with or without cholecystolithiasis,operation methods,operation complication),The chemotherapy A group and chemotherapy B group had no differenceswiththe median survival time and 1,3 and 5-year survival rate after operation.There were significant differences in the median survival time and 3,5-year survival rate after operation between the operation group and chemotherapy A group (or between the operation group and chemotherapy B group).There were significant differences in the rate of whole toxic reaction and the rate of toxic reaction beyond Ⅲ degree between chemotherapy A group and chemotherapy B group.Conclusions The treatment of Tegafur,Gimeracil and Oteracil Potassium Capsule combined with Gemcitabine chemotherapy for patients with radical resection of advanced gallbladder carcinoma has a lower rate of whole toxic reaction and rate of toxic reaction beyond Ⅲ degree than 5-Fluorouracil combined with Oxaliplatin chemotherapy,and for patients with advanced gallbladder carcinoma,the frontal treatment can obviously prolong the median survival time and effectively improve the 3 and 5-year survival rate after operation.

ABSTRACT

Objective To establish a novel method using a nano microfluidic chip to detect circulating tumor cells (CTCs) in peripheral blood in gallbladder carcinoma,and to study the relationship between CTCs with clinicopathology and prognosis in these patients.Methods The peripheral blood samples of 51 patients with gallbladder carcinoma were collected from June 2014 to January 2017.The CTCs from peripheral blood samples were detected by a novel nano microfluidic chip.This study aimed to study the correlation between CTCs with the clinical and pathological features.The significance of CTCs on prognosis in patients with gallbladder carcinoma was also analyzed.Results The positive rate of CTCs in the peripheral blood of gallbladder carcinoma patients was 43.1% (22/51).There were significant correlations between CTCs with liver metastasis (P < 0.05) and Nevin staging (P < 0.05).The 1-and 2-year overall survival (OS) in patients with CTCs were 70.7% and 35.3%,and the 1-and 2-year OS in patients without CTCs were 92.0% and 56.1%.There was a significant difference in the 2-year OS (P < 0.05) but no significant difference in the 1-year OS between the 2 groups of patients (P > 0.05).Conclusions Peripheral blood CTCs in patients with gallbladder carcinoma were efficaciously detected by a novel nano microfluidic chip.Peripheral blood CTCs was closely related to the Nevin staging and liver metastasis.CTCs could serve as a potential prognostic indicator in patients with gallbladder carcinoma.
