AIM:To investigate the prognostic factors after resection for hepatitis B virus(HBV)-associated intrahepatic cholangiocarcinoma(ICC) and to assess the impact of different extents of lymphadenectomy on patient survival.METHODS:A total of 85 patients with HBV-associated ICC who underwent curative resection from January 2005 to December 2006 were analyzed.The patients were classified into groups according to the extent of lymphadenectomy(no lymph node dissection,sampling lymph node dissection and regional lymph node dissection).Clinicopathological characteristics and survival were reviewed retrospectively.RESULTS:The cumulative 1-,3-,and 5-year survival rates were found to be 60 %,18 %,and 13 %,respectively.Multivariate analysis revealed that liver cirrhosis(HR = 1.875,95%CI:1.197-3.278,P = 0.008) and multiple tumors(HR = 2.653,95%CI:1.562-4.508,P 0.001) were independent prognostic factors for survival.Recurrence occurred in 70 patients.The 1-,3-,and 5-year disease-free survival rates were 36%,3% and 0%,respectively.Liver cirrhosis(HR = 1.919,P = 0.012),advanced TNM stage(stage Ⅲ/Ⅳ)(HR = 2.027,P 0.001),and vascular invasion(HR = 3.779,P = 0.02) were independent prognostic factors for disease-free survival.Patients with regional lymph node dissection demonstrated a similar survival rate to patients with sampling lymph node dissection.Lymphadenectomy did not significantly improve the survival rate of patients with negative lymph node status.CONCLUSION:The extent of lymphadenectomy does not seem to have influence on the survival of patients with HBV-associated ICC,and routine lymph nodedissection is not recommended,particularly for those without lymph node metastasis. 相似文献

Background/Purpose
The postoperative outcome of patients who have intrahepatic cholangiocarcinoma with lymph node metastases is extremely poor, and the indications for surgery for such patients have yet to be clearly established.Methods
The demographic and clinical characteristics of 133 patients who underwent lymph node dissection during hepatic resection of intrahepatic cholangiocarcinoma were retrospectively analyzed.Results
Multivariate analysis identified three independent prognostic factors: intrahepatic metastasis, nodal involvement, and tumor at the margin of resection. Of the patients with tumor-free surgical margins, none of the 24 patients who had both lymph node metastases and intrahepatic metastases survived for 3 years. In contrast, the survival rates for the 23 patients who had lymph node metastases associated with a solitary tumor were 35% at 3 years and 26% at 5 years.Conclusions
Surgery alone cannot prolong survival when both lymph node metastases and intrahepatic metastases are present, while surgery may provide a chance for long-term survival in some patients who have lymph node metastases associated with a solitary intrahepatic cholangiocarcinoma tumor.5.
胃癌淋巴结转移规律及其清扫范围探讨 总被引:1,自引:1,他引:0
目的 探讨胃癌淋巴结转移规律及其清扫范围。方法 对188例接受手术治疗的胃癌患者,于术中用美蓝-胃癌单克隆抗体(MAb)3H11标记淋巴结,并对染色淋巴结进行清扫,术后统计切除标本的淋巴结转移情况及病理特征。结果 188例胃癌患者的淋巴结转移率为62.8%(118/188)。胃上1/3(U区)、中1/3(M区)、下1/3(L区)及全胃癌患者的淋巴结转移率分别为61.9%、60.0%、57.5%及95.0%。早、中、晚期胃癌患者淋巴结转移率依次呈递增趋势,P<0.05。浸润型(Ⅲ、Ⅳ型)转移率(76.1%)明显高于局限型(Ⅰ、Ⅱ型)(44.3%),P<0.05。肿瘤直径≤4cm、-7cm和≥8cm者的淋巴结转移率依次增加,差异有显著性,P均<0.01。结论 胃癌淋巴结转移率较高。尤其晚期、浸润型及直径>4cm的胃癌,其淋巴结转移率更高,术中应按胃癌的临床病理分期、部位、大小及Borrman分型,选择淋巴结清扫范围。如果根据术中美蓝-MAb3H11标记结果确定淋巴清扫范围将更准确可靠。 相似文献

Intrahepatic cholangiocarcinoma (ICC) is a rare primary liver cancer with a global increasing trend in recent years. Symptoms tend to be vague and insidious in development, often are diagnosed at an advanced stage when only palliative approaches can be used with a median survival rate of months. Comparing with HCC, ICC tends to spread to lymph nodes early, and is rarely limited to the regional lymph nodes, with a frequent postoperative recurrence. Surgery is the only choice of curative therapy for ICC, but recently no consensus has been established for operation. Thus, more data from multiple centers and more cases are needed. Generally speaking, current adjunctive therapy cannot clearly improve survival. Further research is needed to find more effective radio- and chemotherapeutic regimens. 相似文献

We recently encountered an unusual case of hilar cholangiocarcinoma in which a solitary recurrence in a mediastinal lymph node occurred two years after curative resection of the primary tumor. A 64-year old woman was admitted to our hospital with a complaint of right hypochondrial discomfort. After imaging studies demonstrated a hilar cholangiocarcinoma in the left hepatic duct, a curative resection of the tumor was performed, consisting of a left hepatic lobectomy along with caudate lobectomy, regional lymph node dissection, and resection of the extrahepatic bile duct. No nodal metastasis was observed histologically. Two years after surgery, the patient was found to have a nodule in the posterior mediastinum, which was thoracoscopically resected. No other swollen lymph nodes, local recurrence, or distant metastasis were noted. Histologically, the nodule proved to be a metastatic lymph node, and adjuvant chemoradiation therapy was initiated. The patient remained well for the four years following her first operation and had no evidence of disease recurrence 28 mo after her second operation. To our knowledge, this case is the first report of solitary recurrence in a mediastinal lymph node after curative resection of hilar cholangiocarcinoma. 相似文献

AIM: To assess the effects of 3-field lymphadenectomy for esophageal carcinoma.METHODS: We conducted a computerized literature search of the PubMed, Cochrane Controlled Trials Register, and EMBASE databases from their inception to present. Randomized controlled trials (RCTs) or observational epidemiological studies (cohort studies) that compared the survival rates and/or postoperative complications between 2-field lymphadenectomy (2FL) and 3-field lymphadenectomy (3FL) for esophageal carcinoma with R0 resection were included. Meta-analysis was conducted using published data on 3FL vs 2FL in esophageal carcinoma patients. End points were 1-, 3-, and 5-year overall survival rates and postoperative complications, including recurrent nerve palsy, anastomosis leak, pulmonary complications, and chylothorax. Subgroup analysis was performed on the involvement of recurrent laryngeal lymph nodes.RESULTS: Two RCTs and 18 observational studies with over 7000 patients were included. There was a clear benefit for 3FL in the 1- (RR = 1.16; 95%CI: 1.09-1.24; P < 0.01), 3- (RR = 1.44; 95%CI: 1.19-1.75; P < 0.01), and 5-year overall survival rates (RR = 1.37; 95%CI: 1.18-1.59; P < 0.01). For postoperative complications, 3FL was associated with significantly more recurrent nerve palsy (RR = 1.43; 95%CI: 1.28-1.60; P = 0.02) and anastomosis leak (RR = 1.26; 95%CI: 1.05-1.52; P = 0.09). In contrast, there was no significant difference for pulmonary complications (RR = 0.93; 95%CI: 0.75-1.16, random-effects model; P = 0.27) or chylothorax (RR = 0.77; 95%CI: 0.32-1.85; P = 0.69).CONCLUSION: This meta-analysis shows that 3FL improves overall survival rate but has more complications. Because of the high heterogeneity among outcomes, definite conclusions are difficult to draw. 相似文献

Summary A bicenter study compared survival probability in patients with malignant melanoma clinical stage I, treated by wide excision only or wide excision with elective lymph node dissection (ELND). ELND improved the survival only in men with primary tumors of 1.51–3.0 mm thickness. In female patients those without ELND showed a better survival. Thus, the total group of patients did not benefit from ELND, i.e. its value for the improvement of survival from malignant melanoma stage I could not be statistically proven.Abbreviations ELND

Background
Nodal positivity is a predictor of poor survival following resection for intrahepatic cholangiocarcinoma (ICC). The aim of this study was to evaluate the impact of surgical resection on survival in patients with lymph node (LN) positive ICC.Methods
An augmented version of the Surveillance, Epidemiology, and End Results program database was utilized to identify patients with LN-positive ICC without distant metastases from 2000 to 2014. Patients were stratified by treatment: chemotherapy alone or surgical resection with/without chemotherapy. Survival was evaluated using Kaplan–Meier and Cox proportional hazard models.Results
169 patients who underwent treatment for LN-positive ICC were identified. 88% underwent surgical resection and 12% underwent chemotherapy alone. The median survival for patients who underwent surgical resection was not different from patients treated with chemotherapy alone (19 months 95% Confidence Interval (CI) 17–33 versus 20 months CI 10–27, p = 0.323). A cox-proportional hazard ratio model demonstrated that black race was associated with worse survival (p < 0.05), while surgical resection was not independently associated with survival.Conclusion
Surgical resection for patients with LN-positive ICC may not improve survival compared to chemotherapy alone. Pathologic LN evaluation should be performed prior to surgical resection, to improve patient selection and ensure receipt of optimal therapy. 相似文献15.

Intrahepatic cholangiocarcinoma is the second most common primary liver tumor. The aim of this study was to analyze retrospectively the outcome of surgical treatment and prognostic factors. Clinical, histopathological and treatment data of 221 patients treated from 1995 to 2010 at our institution were investigated. Univariate and multivariate analysis of the patient's data was performed. Patients after R0 and R1 resection presented an overall survival of 67% and 54.5% after 1 year and 40% and 36.4% after 3 years, respectively. The survival of patients without resection of the tumor was dismal with 26% and 3.4% after 1 and 3 years, respectively. Survival after resection was not statistically different in cases with R0 versus R1 resection (P = 0.639, log rank). Univariate Cox regression revealed that higher T stages are a significant hazard for survival (P = 0.048, hazard ratio (HR): 1.211, 95% confidence interval (CI): 1.002–2.465). Patients with tumor recurrence had a significantly inferior long‐term survival when compared to patients without recurrence (P < 0.001, log rank). Presence of lymph node metastasis (N1) was an independent prognostic factor for survival after resection in risk‐adjusted multivariate Cox regression (P < 0.001, HR: 2.577, 95% CI: 1.742–3.813). Adjuvant chemotherapy did not improve patient survival significantly (P = 0.550, log rank). Surgical resection is still the best treatment option for intrahepatic cholangiocarcinoma regarding the patient's long‐term survival. R0 and R1 resection enable both better survival rates when compared to surgical exploration without resection. T status, N status, and tumor recurrence seem to be the most important prognostic factors after resection. 相似文献

AIM: To compare the short- and long-term outcomes of vascularizing lymph node dissection(VLND) and nonvascularizing lymph node dissection(NVLND) from a single institution.METHODS: Data of 315 patients with advanced gastric cancer who underwent standard D2 lymphadenectomy with curative intent was collected between January 1994 and December 2006. One hundred and fifty-two patients received VLND while 163 patients received NVLND. Short- and long-term clinical outcomes were compared between the two groups. RESULTS: The median followed-up time was 82 mo. The rate of postoperative complications in the VLND group was 13.2%, while that in the NVLND group was 11.7%(P = 0.686). The overall 5-year survival rate was 64% in the VLND group and 59% in the NVLND group(P = 0.047). When subgroup analyses were performed according to Bormann type, type of differentiation and lymph node status, survival benefit was demonstrated in patients with Bormann type Ⅲ or Ⅳ(59% vs 50%, P = 0.032), undifferentiated type(63% vs 49%, P = 0.021) or presence of lymph node metastasis(53% vs 38%, P = 0.010) in the VLND group. CONCLUSION: D2 VLND in advanced gastric cancer treatment allows survival benefit with acceptable morbidity and mortality. VLND for patients with potentially curable advanced gastric cancer is feasible and safe when performed by a well-trained surgical team. 相似文献

Sixty-four patients with liver metastases from colorectal cancer were studied to clarify the characteristics of the regional spread of liver metastases (secondary invasive factors) and the effects of major anatomical hepatic resection with lymph node dissection on reducing liver recurrence. No secondary invasive factors, i.e., lymph node metastasis, portal or hepatic vein involvement, bile duct involvement, micrometastasis, and direct invasion, were observed in patients with liver metastases less than 3 cm in diameter (5-year survival rate; 100%). Secondary invasive factors were seen in 19.2% of the patients with liver metastases from 3 cm to less than 6 cm (5-year survival rate; 28.7%), and in 45.2% of those with liver metastases 6 cm and over (5-year survival rate; 14.6%). Secondary invasive factors were noted in 45% of the patients with recurrence in the remmant liver. Although 31% of all 64 patients exhibited secondary invasive factors, major anatomical hepatic resection with lymph node dissection achieved a low liver recurrence rate of 31.3%. In conclusion, considering the risks attributed to secondary invasive factors, major anatomical hepatic resection with lymph node dissection is an appropriate surgical procedure for patients with liver metastases exceeding 3 cm in diameter. 相似文献

AIM To develop a contrast-enhanced ultrasound(CEUS)predictive model for distinguishing intrahepatic cholangiocarcinoma(ICC) from hepatocellular carcinoma(HCC) in high-risk patients.METHODS This retrospective study consisted of 88 consecutive high-risk patients with ICC and 88 high-risk patients with HCC selected by propensity score matching between May 2004 and July 2016. Patients were assigned to two groups, namely, a training set and validation set, at a 1:1 ratio. A CEUS score for diagnosing ICC was generated based on significant CEUS features. Then, a nomogram based on the CEUS score was developed, integrating the clinical data. The performance of the nomogram was then validated and compared with that of the LR-M of the CEUS Liver Imaging Reporting and Data System(LI-RADS).RESULTS The most useful CEUS features for ICC were as follows: rim enhancement(64.5%), early washout(91.9%), intratumoral vein(58.1%), obscure boundary of intratumoral non-enhanced area(64.5%), and marked washout(61.3%, all P 0.05). In the validation set, the area under the curve(AUC) of the CEUS score(AUC = 0.953) for differentiation between ICC and HCC was improved compared to the LI-RADS(AUC = 0.742)(P 0.001). When clinical data were added, the CEUS score nomogram was superior to the LI-RADS nomogram(AUC: 0.973 vs 0.916, P = 0.036, Net Reclassification Improvement: 0.077, Integrated Discrimination Index: 0.152). Subgroup analysis demonstrated that the CEUS score model was notably improved compared to the LIRADS in tumors smaller than 5.0 cm(P 0.05) but not improved in tumors smaller than 3.0 cm(P 0.05).CONCLUSION The CEUS predictive model for differentiation between ICC and HCC in high-risk patients had improved discrimination and clinical usefulness compared to the CEUS LIRADS. 相似文献

AIM: To carry out a hospital-based case-control study to investigate risk factors for intrahepatic cholangiocarcinoma (ICC) in China. METHODS: A total of 312 ICC cases and 438 matched controls were included in the study. The presence of diabetes mellitus, hypertention, hepatolithiasis, primary sclerosing cholangitis, liver fluke infection (Clonorchis sinensis), was investigated through clinical records. Blood from all participants was tested for hepatitis B surface antigen (HBsAg) and anti-HCV antibodies. Odds ratios (OR) and 95% confidence intervals (95% CI) were estimated using conditional logistic regression. RESULTS: Compared with controls, ICC patients had a higher prevalence of HBsAg seropositivity (48.4% vs 9.6%, P 〈 0.000), and hepatolithiasis (5.4% vs 1.1%, P = 0.001). By multivariate analysis, the significant risk factors for development of ICC were HBsAg seropositivity (adjusted OR, 8.876, 95% CI, 5.973-13.192), and hepatolithiasis (adjusted OR, 5.765, 95% CI, 1.972-16.851). The prevalence of anti-HCV seropositivity, diabetes mellitus, hypertention, cigarette smoking, and alcohol consumption were not significantly different between cases and controls. CONCLUSION: These findings suggest that HBV infection and hepatolithiasis are strong risk factors for development of ICC in China. 相似文献
