肝切除术是目前公认的治疗肝癌的首选方式,但术后肿瘤复发率较高.中国肝癌患者多数合并乙肝感染,乙肝病毒(HBV)因素如:病毒基因型、血清e抗原状态、血清HBV DNA水平、肝内HBV DNA水平与肝切除术后肿瘤复发相关.抗病毒治疗,尤其是干扰素治疗可能是预防肝癌复发的有效方式之一.乙肝病毒因素也可影响肝移植术后患者复发率. 相似文献

BACKGROUND: Liver transplantation achieves better results when hepatocellular carcinoma fits the Milan criteria. This study investigated predictors of recurrent hepatocellular carcinoma exceeding the Milan criteria. METHODS: Among 285 patients with hepatocellular carcinoma fitting the Milan criteria who underwent curative resection, 143 patients suffered initial recurrence (92 had tumors fitting the criteria) and 71 patients suffered a second recurrence (40 conforming tumors). RESULTS: Survival after hepatectomy was significantly worse when initial recurrence was nonconforming. Similarly, survival after initial recurrence was significantly worse when the second recurrence was nonconforming. A preoperative increase of protein induced by vitamin K absence/antagonist II, a tumor diameter of 3 cm or greater, age of 65 years or younger, and intraoperative blood transfusion increased the risk of nonconforming initial recurrence. CONCLUSIONS: Liver transplantation should be considered initially for younger patients with hepatocellular carcinoma fitting the Milan criteria, larger tumors, and an increase of protein induced by vitamin K absence/antagonist II. 相似文献

Background/Purpose Systematic hepatectomy for small hepatocellular carcinoma (HCC) is a widely preferred modality, but evidence concerning its
benefits is lacking. The aim of this study was to document hepatic resection for small HCC in Korea, and to determine whether
patient survival or the pattern of tumor recurrence was influenced by the methods used.
Methods Ten major hospitals that perform hepatectomy for HCC in Korea were surveyed for surgeons' opinions concerning systematic hepatectomy
and current trends in hepatic resection for small HCC. An analysis was also performed of 119 patients who underwent curative
hepatectomy for small HCC (size < 5 cm) between January 2000 and December 2002 at Seoul National University Hospital. Seventy-four
of these 119 patients underwent anatomical resection (AR) and 45 had a nonanatomical resection (NAR). Recurrence-free survival,
recurrence pattern, overall survival rates, and the risk factors for recurrence were analyzed.
Results In the survey, eight of ten surgeons preferred systematic hepatectomy and considered it to aid prognosis. No significant difference
was found between the AR and NAR groups in terms of the clinicopathologic findings, except that the presence of underlying
hepatic cirrhosis was more prevalent in the NAR group. The postoperative morbidity rate was higher in the NAR group (33.3%
vs 27.0%), but this difference was not statistically significant. The respective 1- and 3-year recurrence-free survival rates
were 78.1% and 49.7% in the AR group, and 68.9% and 46.5% in the NAR group (P > 0.05). The corresponding 1- and 3-year overall survival rates were 88.8% and 80.8% in the AR group and 91.0% and 71.4%
in the NAR group (P > 0.05).
Conclusions Although systematic hepatectomy seems to be superior to nonanatomical hepatectomy from the oncological and anatomical aspects,
this superiority is not reflected by the recurrence patterns or the survival and recurrence rates of the two procedures. Postoperative
recurrence appears, rather, to be related to the underlying liver condition. 相似文献

目的 探讨拉米夫定防治乙肝病毒在肝癌围手术期活跃的效果。方法 对72例肝癌合并HBV感染者随机分组,研究组的38例在围手术期每日1次给予拉米夫定100mg,进行定量HBV DNA及其它检查。对照组在围手术期不进行抗乙肝病毒治疗。结果 对照组的HBV DNA量,在术后1周内、2周内较术前的增高值具显著性意义(P<0.01),研究组中术后1周内、2周内HBV DNA量较术前的HBV DNA量低值亦有显著性意义(P<0.01),皆低于安全治愈阈值;两组的术前、术后Child分级,术前、术后ALT比较差异无显著性意义(P>0.05)。术后2周内并发症发生率比较,差异有显著性意义(P<0.05)。结论 外科治疗可激活HBV的复制能力,须加强肝癌围手术期对HBV的防范。拉米夫定有强大的抗HBV功能,可短期内迅速降低HBV DNA的量至安全范围,应用拉米夫定可以预防和治疗肝癌围手术期乙肝病毒的活跃。但其短期内改善肝脏功能的效果不明显。 相似文献

We report two cases of early primary hepatocellular carcinoma (PHC) in children, after probable maternal transmission of hepatitis B, that were treated with orthotopic liver transplantation (OLT). Both children were 8.5 years old and had elevated levels of serum alpha-fetoprotein. The diagnosis of PHC was made at 8 years and confirmed histologically. Serum hepatitis B surface antigen (HBs Ag) was detected in the mothers and suggested vertical transmission. An attempt at complete liver tumor resection failed, leading to OLT. In order to prevent recurrence of the hepatitis B virus (HBV) infection, hepatitis B immunoprophylaxis was used. Two years after OLT, one child presented with recurrent HBV infection. No tumor recurrence was observed at follow-up in either of the patients. From these two cases we conclude that (1) HBV infection may play an important causal role in PHC in children, with an even shorter incubation period than that in adults; (2) close follow-up is needed for children who are HBs Ag-positive carriers; and (3) liver transplantation should be proposed early after the diagnosis of PHC, when tumor resection is not feasible. 相似文献

BACKGROUND: The aim of this study is to identify the risk factors of survival and recurrence after curative hepatic resection for stage IV-A hepatocellular carcinoma (HCC). METHODS: Sixty-five patients with stage IV-A HCC who underwent curative hepatic resection and discharged from hospital were enrolled in this retrospective study. Prognostic factors were evaluated by univariate and multivariate analysis. Clinicopathologic features and survival with stage IV-A HCC were compared with those of 290 patients with stage I to III HCC who underwent curative hepatic resection during the same period. RESULTS: Disease-free and overall survival for patients with stage IV-A HCC was significantly lower than for those with stage I to III HCC. Positive hepatitis B virus (HBV) surface antigen was an independent prognostic factor of poor disease-free and overall survivals in patients with stage IV-A HCC. There were no significant differences in the disease-free and overall survivals between non-HBV-related stage IV-A HCC and stage I to III HCC. CONCLUSIONS: Even for patients with highly advanced HCC, curative hepatic resection may be a feasible therapeutic option for those with non-HBV-related HCC. 相似文献

Background Although extrahepatic metastasis occurs rarely after hepatic resection for hepatocellular carcinoma (HCC), the prognosis of
these patients is extremely poor. Predictors of extrahepatic metastasis have not been fully investigated.
Methods To identify predictors of extrahepatic metastasis after resection, we retrospectively investigated 77 patients with HCC tumors
>50 mm in diameter who underwent hepatic resection. We investigated correlations between postoperative extrahepatic metastasis
and clinicopathologic factors as well as extrahepatic metastasis-free survival rate by log rank test and predictors of extrahepatic
metastasis by univariate and multivariate logistic regression models.
Results Hepatitis B surface antigen (HBs-Ag) was found in 25 (32.5%) of 77 patients, and extrahepatic metastasis occurred in 26 (33.8%).
Patients with extrahepatic metastasis showed better liver function and a high occurrence of HBs-Ag positivity than those without.
The 5-year extrahepatic metastasis-free survival rate was worse in patients with HBs-Ag positivity, larger tumors (≥70 mm),
higher alfa-fetoprotein level (≥300 ng/mL), and lower indocyanine green retention rate at 15 minutes (ICGR15) (<15%) than in those without. By univariate logistic regression analysis, HBs-Ag positivity, larger HCC tumor (≥70 mm),
lower ICGR15 (<15%), and lower preoperative lymphocyte count (<1000/mm3) were predictors of extrahepatic metastasis (P < .1). By multivariate analysis, HBs-Ag positivity was an independent predictor of postoperative extrahepatic metastasis
(P = .04).
Conclusions In patients positive for HBs-Ag, radiologic examination of extrahepatic organs should be performed as a part of the postoperative
surveillance. Hepatitis B virus infection may promote establishment of extrahepatic metastasis. 相似文献

Prognostic impact of anatomical resection on early and late intrahepatic recurrence in patients with hepatocellular carcinoma 总被引:10,自引:0,他引:10

Background/Purpose Little has been addressed regarding the impact of the type of resection, which can be anatomical or nonanatomical, for patients
with hepatocellular carcinoma (HCC), from the viewpoint of early (≤2-year) and late (>2-year) intrahepatic recurrence. The
aim of the present study was to investigate this issue.
Methods Between 1990 and 2004, we performed 365 potentially curative liver resections. Among these, 233 patients with a solitary tumor
were the subjects of this study. They were classified into two groups: anatomical resection (n = 106) and nonanatomical resection (n = 127). We evaluated the following outcomes: (1) early and late recurrence rates; (2) topography of the recurrent tumors;
and (3) risk factors for early recurrence.
Results The early recurrence rate after anatomical resection was significantly lower than that after nonanatomical resection: recurrence
rates at 1 and 2 years were 13.8% and 29.8%, respectively, in the former group; while they were 22.6% and 46.3%, respectively,
in the latter group (P = 0.01; log-rank test). However, late recurrence rates were similar in the two groups (P = 0.36). Local recurrence was observed in 25 of the 89 patients with intrahepatic recurrence after nonanatomical resection
(28%), whereas it was observed in 3 of the 64 patients with intrahepatic recurrence after anatomical resection (5%), showing
a significantly lower local recurrence rate in the anatomical resection group (P = 0.0002). Cox multivariate analysis identified the type of resection employed as one of the variables contributing to early
HCC recurrence (nonanatomical resection: hazard ratio, 1.84; 95% confidence interval [CI], 1.01–3.37).
Conclusions Anatomical resection would be a more appropriate strategy than nonanatomical resection for preventing early intrahepetic recurrence
in patients with solitary HCC. However, the type of resection has no significant influence on late recurrence. 相似文献

Despite recent progress in diagnostics for hepatocellular carcinoma, the rate of resectability remains low, mainly because of the advancement of the underlying liver disease. We report a case of a 54-year-old man with a hepatocellular carcinoma and poor liver function that was treated successfully with a laparoscopic hepatic resection. Laparoscopic hepatic resection is considered to be feasible with the aid of an ultrasonic dissector and a microwave coagulator; however, close attention should be paid to the development of air embolism and hepatic vein injury. 相似文献
