肝内胆管细胞癌外科治疗进展

手术切除是肝内胆管细胞癌首选的治疗方法,也是唯一可能的治愈手段。R0切除是影响肝内胆管细胞癌手术预后的重要因素,在保证R0切除和手术安全性的基础上,切缘距离应>10 mm。淋巴结是否转移是肝内胆管细胞癌手术最重要的预后因素之一,淋巴结清扫能改善患者的预后,术后辅以系统治疗可以延长患者的生存期。对于起始不可切除的肝内胆管细胞癌患者,辅助化疗是一个可能获得根治性手术切除机会的有效措施。     

腹腔镜肝切除术治疗肝内胆管结石病患者临床疗效研究*

Surgery and chemotherapy for intrahepatic cholangiocarcinoma

Cholangiocarcinoma, arising from bile duct epithelium, is categorized into intrahepatic cholangiocarcinoma (ICC) and extrahepatic cholangiocarcinoma (ECC), including hilarcholangiocarcinoma. Recently, there has been a worldwide increase in the incidence and mortality from ICC. Complete surgical resection is the only approach to cure the patients with ICC. However, locoregional extension of these tumors is usually advanced with intrahepatic and lymph-node metastases at the time of diagnosis. Resectability rates are quite low and variable (18%-70%). The five-year survival rate after surgical resection was reported to be 20%-40%. Median survival time after ICC resection was 12-37.4 mo. Only a small number of ICC cases, accompanied with ECC, gall bladder carcinoma, and ampullary carcinoma, have been reported in the studies of chemotherapy due to the rarity of the disease. However, in some reports, significant anti-cancer effects were achieved with a response rate of up to 40% and a median survival of one year. Although recurrence rate after hepatectomy is high for the patients with ICC, the residual liver and the lung are the main sites of recurrence after tentative curative surgical resection. Several patients in our study had a long-term survival with repeated surgery and chemotherapy. Repeated surgery, combined with new effective regimens of chemotherapy, could benefit the survival of ICC patients.     

Clinicopathological and prognostic analysis of 429 patients with intrahepatic cholangiocarcinoma

AIM: To understand the clinicopathological characteristics and treatment selections and improve survival and provide valuable information for patients with intrahepatic cholangiocarcinoma (ICC). METHODS: We retrospectively evaluated 5311 liver cancer patients who received resection between October 1999 and December 2003. Of these, 429 (8.1%) patients were diagnosed with ICC, and their clinicopathological, surgical, and survival characteristics were analyzed. RESULTS: Upper abdominal discomfort or pain (65.0%), no symptoms (12.1%), and hypodynamia (8.2%) were the major causes for medical attention. Laboratory tests showed 198 (46.4%) patients were HBsAg positive, 90 (21.3%) had α-fetoprotein > 20 μg/L, 50 (11.9%) carcinoembryonic antigen > 10 μg/L, and 242 (57.5%) carbohydrate antigen 19-9 (CA19-9) > 37 U/mL. Survival data was available for 329 (76.7%) patients and their mean survival time was 12.4 mo. The overall survival of the patients with R0, R1 resection and punching exploration were 18.3, 6.6 and 5.6 mo, respectively. Additionally, CA19-9 > 37 U/mL was associated with lymph node metastases, but inversely associated with cirrhosis. Multivariate analysis indicated that radical resection, lymph node metastases, macroscopic tumor thrombi and size, and CA19-9 were associated with prognosis.CONCLUSION: Surgical radical resection is still the most effective means to cure ICC. Certain laboratory tests (such as CA19-9) can effectively predict the survival of the patients with ICC.     

A case of intrahepatic clear cell cholangiocarcinoma

Intrahepatic clear cell cholangiocarcinoma is very rareonly 8 cases have been reported.A 56-year-old Japanese man with chronic hepatitis B infection was diagnosed with a 2.2 cm hepatocellular carcinoma on imaging,and hepatic segmentectomy was performed.Histopathologically,the tumor cells had copious clear cytoplasm and formed glandular structures or solid nests.These pathological findings suggested the tumor was a clear cell variant of intrahepatic cholangiocarcinoma.Particular stains and radiological image...     

肝内胆管癌患者术后预后研究

目的 探讨影响肝内胆管癌（ICC）患者术后生存的因素。方法 2011年12月~2015年2月我院诊治的ICC患者94例,对其中35例行姑息性治疗,即肝内扩张胆管置管引流术,对另59例行根治性肿瘤切除术。采用单因素分析和多因素回归分析影响ICC患者术后生存的因素。结果 经随访,本组94例ICC患者生存期为3~35个月,平均为（26.1±4.6）个月;1 a生存率为76.6%,2a生存率为7.4%;单因素分析显示,ICC肿瘤数目、直径、肿瘤分化、血清CEA、CA19-9和是否发生淋巴结转移和远处转移以及手术方法为影响术后患者生存的因素（P<0.05）;经多因素回归分析,发现肿瘤多发、低程度分化、血清CEA大于25 μg/L、血清CA19-9大于182 U/ml、手术切除组织边缘肿瘤细胞阳性、淋巴结转移和姑息性手术是影响ICC患者术后生存的危险因素（P<0.05）。结论 ICC患者预后差,很多患者在诊断时已失去根治性切除肿瘤的机会,即使获得肿瘤切除而根治的患者仍存在很多影响预后的危险因素,临床医生需认真研究这些因素,而给予相应的处理。     

Clinical parameters predicting survival duration after hepatectomy for intrahepatic cholangiocarcinoma

BACKGROUND:

Currently, the most effective treatment for intrahepatic cholangiocarcinoma (ICC) is complete hepatic tumour excision.

OBJECTIVE:

To identify the clinical parameters associated with survival duration for ICC patients following hepatectomy, and to construct a mathematical model for predicting survival duration.

METHODS:

Demographic data and clinical variables for 102 patients diagnosed with ICC, who underwent exploratory laparotomy at a single centre from July 1998 to December 2000 and were followed for an average of 24 months, were collected in 2011. Patients were randomly assigned into training (n=76) and validation (n=26) groups. Univariate and multivariate analyses were performed to identify factors associated with posthepatectomy survival duration.

RESULTS:

Univariate analysis revealed that more than three lymph node metastases, a serum carbohydrate antigen 19-9 level >37 U/mL, stage IVa tumours, and intra- or perihepatic metastases were significantly associated with decreased survival duration. Curative resection was significantly associated with increased survival duration. A mathematical model incorporating parameters of age, sex, metastatic lymph node number, curative surgery, carbohydrate antigen 19-9 concentration, alpha-fetoprotein concentration, hepatitis B, TNM stage and tumour differentiation was constructed for predicting survival duration. For a survival duration of less than one year, the model exhibited 93.8% sensitivity, 92.3% total accuracy and a positive predictive value of 93.8%; for a survival duration of one to three years, the corresponding values were 80.0%, 69.2% and 57.1%, repsectively.

CONCLUSIONS:

The mathematical model presented in the current report should prove to be useful in the clinical setting for predicting the extent to which curative resection affects the survival of ICC patients, and for selecting optimal postoperative treatment strategies.
