ABSTRACT
Objective To investigate clinical efficacy and prognostic factors of hilar cholangiocarcinoma.Methods The retrospective case-control study was conducted.The clinicopathological data of 322 patients with hilar cholangiocarcinoma who were admitted to the Xiangya Hospital of Central South University between December 2005 and November 2015 were collected.Preoperative staging and classification of tumor and treatment planning were carried out according to the results of laboratory and imaging examinations.Observation indexes:(1) clinical features and results of assisted examinations;(2) treatments and results of pathological examination;(3) followup and survival;(4) prognostic factors analysis:gender,age,preoperative highest total bilirubin (TBil),preoperative carcinoembryonic antigen (CEA),preoperative CA19-9,preoperative CA242,preoperative CA125,treatment methods and TNM staging.The follow-up of outpatient examination and telephone interview was perfornmed to detect patients' survival up to November 2016.Survival curve was drawn using the Kaplan-Meier method.Survival and univariate analyses were done using the Log-rank test,and multivariate analysis was done using the Cox proportional hazard model.Results (1) Clinical features and results of assisted examinations:among the 322 patients,there were 301 patients with a chief complaint of jaundice.Of the 322 patients,the preoperative highest levels of TBil,DBil,ALT and AST in 322 patients were 3.9-785.2 μmol/L,1.6-410.2 μ mol/L,14.8-484.5 U/L and 21.4-539.8 U/L,respectively.Levels of ALP and GGT in 272 patients were 93.8-1 890.0 U/L and 2.0-1 832.8 U/L,respectively.Seventy-seven of 292 patients had an elevated CEA level,272 of 298 patients had an elevated CA19-9 level,153 of 260 patients had an elevated CA242 level and 86 of 260 patients had an elevated CA125 level.According to Bismuth-Corlette type,24 patients were detected in type Ⅰ,115 in type Ⅱ,55 in type Ⅲa,63 in type Ⅲb and 65 in type Ⅳ.(2) Treatments and results of pathological examination:Of the 322 patients,104 patients underwent radical resection,including 79 with hilar bile duct resection (9 combined with vascular resection and reconstruction) and 25 with extended hepatic lobectomy (16 combined with caudate lobectomy),and 218 patients underwent palliative treatments,including 134 with external biliary drainage and 84 with internal biliary drainage.Five patients were dead in the perioperative period,of which 2 died of acute liver failure,1 died of systemic infection and multiple organ failure,1 died of acute renal failure and 1 died of acute suppurative cholangitis,septic shock and disseminated intravascular coagulation.Of 263 patients receiving pathological examination,adenocarcinoma was detected in 253 patients (12 with high-differentiated adenocarcinoma,85 with moderate-differentiated adenocarcinoma,33 with low-differentiated adenocarcinoma and 123 with indefinite differentiation),mucinous adenocarcinoma in 5 patients,cholangiocarcinoma in 3 patients and neuroendocrine carcinoma in 2 patients.TNM staging of 322 patients:stage Ⅰ was detected in 8 patients,stage Ⅱ in 53 patients,stage Ⅲ in 132 patients,stage Ⅳ in 96 patients and indefinite stage in 33 patients.(3) Follow up and survival:among the 322 patients,296 were followed up for 12-132 months,with a median follow-up time of 65 months,including 94 with radical resection and 202 with palliative treatments.Among the 296 patients,the median survival time and 1-,3-,5-year survival rates were 10 months,47.1％,20.2％ and 9.5％,respectively.0f296 patients with follow-up,median survival time and 1-,3-,5-year survival rates were 31 months,84.0％,46.2％,25.0％ in 94 patients receiving radical resection and 7 months,29.9％,8.1％ and 2.3％ in 202 patients receiving palliative treatment,respectively,with a statistically significant difference between the 2 groups (x2=78.777,P＜ 0.05).Among the 94 patients receiving follow-up and radical resection,the median survival time and 1-,3-,5-year survival rates were 31 months,82.1％,45.1％,25.7％ in 73 patients undergoing hilar bile duct resection and 35 months,90.5％,49.8％,22.1％ in 21 patients undergoing hepatic lobectomy,respectively,with no statistically significant difference (x2=0.186,P＞0.05).Among the 73 patients undergoing hilar bile duct resection,median survival time and 1-,3-,5-year survival rates were 16 months,57.1％,0,0 in 7 patients combined with vascular resection and reconstruction and 34 months,84.6％,49.5％,27.5％ in 66 patients undergoing simplex hilar bile duct resection,respectively,showing a statistically significant difference (x2 =11.977,P＜ 0.05).(4) Prognostic factors analysis:results of univariate analysis showed that preoperative highest TBil,preoperative CEA,preoperative CA242,preoperative CA125,treatment methods and TNM staging were related factors affecting prognosis of patients with hilar cholangiocarcinoma (x2=25.009,18.671,9.359,33.628,94.729,77.136,P＜0.05).Multivariate analysis showed that preoperative highest TBil ≥ 342.0 μmol/L,preoperative CEA ≥ 5.00 μg/L,palliative treatments,TNM stage Ⅲ and Ⅳ were the independent risk factors affecting the poor prognosis of patients with hilar cholangiocarcinoma (HR =2.270,2.147,3.166,2.351,95％ confidence interval:1.587-3.247,1.446-3.188,2.117-4.734,1.489-3.712,P＜0.05).Conclusions Prognosis of hilar cholangiocarcinoma is still unsatisfactory.The R0 resection is the key in radical surgery.Preoperative highest TBil≥342.0 μmol/L,preoperative CEA ≥ 5.00 μg/L,palliative treatments,TNM stage Ⅲ-Ⅳ are independent risk factors affecting the poor prognosis of patients with hilar cholangiocarcinoma.
ABSTRACT
Objective To evaluate the diagnostic and therapeutic methods for hilar bile duct carcinoma. Methods The clinical data of 36 patients with hilar bile duct carcinoma from Jan 1998 to Jul 2003 were retrospectively analyzed. Results The misdiagnosis rate(39%) was high. All patients underwent a surgery. The median survival time of 16 patients treated by radical resection was 30 months. The 1,3,5-year survival rate was 93%,50% and 25% respectively. While the median survival time of the rest 20 patients treated by a variety of non-radical operation was 16 months with 1,3,5-year survival rate of 47%,8% and 0 respectively(t=2.585).Conclusions Early diagnosis and radical resection improves long-term survival of patients with hilar bile duct carcinoma.
ABSTRACT
Objective To evaluate the therapeutic effect of segmental hepatectomy for intrahepatic bile duct stones.Methods In this study, 414 patients suffering from intrahepatic bile duct stones underwent hepatectomy from Jan 1981 to Dec 2001. Stones distribution, operation modality,postoperative complication and therapeutic effect were evaluated. Results Postoperative complications occurred in 72 cases(17.4%), mortality was 0.7%. A follow up of 2 to 22 years was achieved in 305 patients (73.7%), with excellent or good result in 88.9%, residual stone in 15.7%,and stone recurrence in 4.6%.Conclusion Appropriate use of hepatectomy is effective for the treatment of intrahepatic bile duct stones.
ABSTRACT
Objective To investigate the timing of operation and the selection of surgical procedure for acute biliary pancreatitis.Methods The clinical data of 247 cases of acute biliary pancreatitis were retrospectively analysed.Results Among 10 non-operation patients,4 died;12 patients underwent emergency operation,5 had postoperative complications and 2 patients died after operation.169 patients underwent delayed operation after effective conservative therapy and 1 patient had postoperative complication;56 patients underwent(selective) operation without any postoperative complication or death.Conclusions Early emergency operation should be performed for relief of biliary obstruction in acute biliary obstructive pancreatitis.The patients with acute non-obstructive biliary pancreatitis should undergo conservative therapy at first and then,after(pancreatitis) has been controlled,delayed operation or selective operation to treat the biliary pathologic condition should be performed.
ABSTRACT
Objective To study the significance of expression of VEGF in the hepatocellular carcinoma tissue(HCT) and the expression of AFPmRNA in the peripheral vein blood in hepatocellular carcinoma patients(HCC) with metastasis. Methods AFPmRNA was detected in peripheral blood before operation and the expression of VEGF in HCC tissue was analyzed by immunohistochemistry after operation in 20 patients. The relations between the expression of VEGF protein and AFPmRNA with clinicpathological parameters were analyzed statistically. Results (1)Among the 20 patients with HCC, 10 were positive expression of VEGF protein, which had no relation with the clinicopathological parameters. (2)Of the 20 patients, positive expression of AFPmRNA were detected in the peripheral blood in 15 patients, and AFP≥200?g/L were found in 13 patients.(3) AFPmRNA in the peripheral blood vein was detected in 9 of 10 patients with VEGF positive expression. Conclusions (1)Either VEGF protein expressed in HCC tissue or AFPmRNA detected in the peripheral blood could be as a guide line to judge the tendency of the metastasis of HCC,however former is simpler and the later is more sensitive . (2)The detection of AFPmRNA in the peripheral blood is more sensitive than the detection of serum AFP lever for surveillance of the high risk patients and postoperative follow up of the patients with HCC.
