Objective To study the preventive effects of vitamin K2 on tumor recurrence in patients with hepatocellalar carcinoma (HCC) after radical resection. Methods The clinical data of 50 patients with HCC who received radical resection from March 2006 to March 2007 in No. 181 Hospital of PLA were analyzed retrospec-tively. All the patients were divided into 2 groups according to the random number table. Twenty-six patients in vitamin K2 group were administered with menatetrenone (45 mg per day), and the rest 24 pateints were in the control group. The accumulative and tumor-free survival rates, differences between the 2 groups, multivariate factors for prognosis were analyzed by Kaplan-Meier curve, Log-rank test and Cox regression model, respectively. Results During a period of 36 month follow-up, 10 patients died and 28 had tunor recurrence. The 1-, 2-, 3-year accumulative survival rates were 96%, 92% and 83% in vitamin K2 group, and 96%, 82% and 63% in control group (χ2 = 3.61, P > 0.05). The 1-, 2-, 3-year tumor-free survival rates were 92%, 60% and 38% in vitamin K2 group, and 75%, 42% and 12% in control group, with significant difference between the 2 groups (χ2 =5.61, P <0.05). Univariate and multivariate Cox proportional hazard analysis showed that without taking menate-trenone, the preoperative level of alpha fetoprotein (AFP) ≥800 μg/L and vascular invasion were the indepen-dent risk factors for tumor recurrence. Conclusions Vitamin K2 has a suppressive effect on tumor recurrence of HCC, while patients with AFP≥800 μg/L before operation or with vascular invasion have poor prognosis. 相似文献

Objective To compare the clinical efficacy of postoperative intraperitoneal chemotherapy combined with systemic chemotherapy to systemic chemotherapy alone for serosa-involved colorectal cancer. Methods According to the criteria of serosa-involving in colorectal cancer, 332 cases were divided into 2 groups prospectively without randomization. Study group (n=166) was treated with intraperitoneal chemotherapy combined with systemic chemotherapy, and control group (n=166) with systemic chemotherapy alone. Incidence of local recurrence, peritoneal metastasis, hepatic metastasis, other distant metastasis and 3-year, 5-year overall survival (OS) rate of two groups were compared. Results 3-year and 5-year OS rates of stage Ⅱ B in study group were similar to those in control group (χ2=0.612,P=0.434). The above rates of stage Ⅲ in study group were higher than those in control group (χ2=3.989,P=0.046). Either the study group or the control group, the 3-year and 5-year OS rates of patients undergone laparoscopic surgery or open surgery were similar (P=0.839, P=0.172). Incidences of local recurrence, peritoneal metastasis and hepatic metastasis in study group were 1.9%, 3.8% and 3.8% respetively, lower than those in control group (8.2%,9.5% and 10.1%,P<0.05). Distant metastasis rate in study group was similar to that in control group. In study group, intraperitoneal chemotherapy regimen with Oxaliplatin had lower rates of peritoneal metastasis and hepatic metastasis as compared to that with Cisplatin (0.9% vs 8.8% ,P=0.019), while the incidences of local recurrence and other distant metastasis were similar. Conclusions Postoperative intraperitoneal chemotherapy combined with systemic chemotherapy improves 3-year and 5-year overall survival rates in patients with stage Ⅲ serosa-involved colorectal cancer, and decreases local recurrence, peritoneal metastasis and liver metastasis rate, especially when intraperitoneal chemotherapy regimen contains Oxaliphtin. Comparing with open surgery, laparoscopic surgery dose not improve 3-year and S-year overall survival rates in patients receiving combined chemotherapy or systemic chemotherapy alone. 相似文献

Living donor versus deceased donor liver transplantation for early irresectable hepatocellular carcinoma 总被引:4,自引:0,他引:4
BACKGROUND: Hypothetical studies that favour living donor liver transplantation (LDLT) for early hepatocellular carcinoma (HCC) assumed a comparable outcome after LDLT and deceased donor liver transplantation (DDLT). The aim of this study was to compare the outcome after LDLT with that after DDLT, and to identify factors that might account for any differences. METHODS: The study included 60 patients who met the radiological Milan or University of California at San Francisco (UCSF) criteria and underwent LDLT (43 patients) or DDLT (17). RESULTS: The LDLT group had fewer incidental tumours and a lower rate of pretransplant transarterial chemoembolization but a higher rate of salvage transplantation. Waiting time was shorter and graft weight to standard liver weight (GW : SLW) ratio was lower in this group. The perioperative course, and histopathological tumour size, number, grade and stage were comparable. Median follow-up was 33 (range 4-120) months. The cumulative 5-year recurrence rate was 29 per cent in the LDLT group and 0 per cent in the DDLT group (P = 0.029). A GW : SLW ratio of 0.6 or less, salvage transplantation, three or more tumour nodules, microscopic vascular invasion, and pathological stage beyond the Milan or UCSF criteria were significant confounding risk factors. Multivariable analysis identified salvage transplantation (relative risk 5.16 (95 per cent confidence interval (c.i.) 1.48 to 18.02); P = 0.010) and pathological stage beyond the UCSF criteria (relative risk 4.10 (95 per cent c.i. 1.02 to 16.48); P = 0.047) as independent predictors of recurrence. CONCLUSION: Despite standard radiological selection criteria based on number and size, patients who underwent LDLT for HCC had more recurrence because of selection bias for other clinical characteristics. 相似文献

Several studies have reported higher rates of recurrent hepatocellular carcinoma (HCC) after living donor liver transplantation (LDLT) versus deceased donor liver transplantation (DDLT). It is unclear whether this difference is due to a specific biological effect unique to the LDLT procedure or to other factors such as patient selection. We compared the overall survival (OS) rates and the rates of HCC recurrence after LDLT and DDLT at our center. Between January 1996 and September 2009, 345 patients with HCC were identified: 287 (83%) had DDLT and 58 (17%) had LDLT. The OS rates were calculated with the Kaplan-Meier method, whereas competing risks methods were used to determine the HCC recurrence rates. The LDLT and DDLT groups were similar with respect to most clinical parameters, but they had different median waiting times (3.1 versus 5.3 months, P = 0.003) and median follow-up times (30 versus 38.1 months, P = 0.02). The type of transplant did not affect any of the measured cancer outcomes. The OS rates at 1, 3, and 5 years were equivalent: 91.3%, 75.2%, and 75.2%, respectively, for the LDLT group and 90.5%, 79.7%, and 74.6%, respectively, for DDLT (P = 0.62). The 1-, 3-, and 5-year HCC recurrence rates were also similar: 8.8%, 10.7%, and 15.4%, respectively, for the LDLT group and 7.5%, 14.8%, and 17.0%, respectively, for the DDLT group (P = 0.54). A regression analysis identified microvascular invasion (but not the graft type) as a predictor of HCC recurrence. In conclusion, in well-matched cohorts of LDLT and DDLT recipients, LDLT and DDLT provide similarly low recurrence rates and high survival rates for the treatment of HCC. 相似文献

The aim of this work is to study the different factors that affect the outcome of living donor liver transplantation for patients with hepatocellular carcinoma (HCC). Between April 2003 to November 2014, 62 patients with liver cirrhosis and HCC underwent living donor liver transplantation (LDLT) in the National Liver Institute, Menoufia University, Egypt. The preoperative, operative, and postoperative data were analyzed. After studying the pathology of explanted liver; 44 (71 %) patients were within the Milan criteria, and 18 (29 %) patients were beyond Milan; 13 (21.7 %) of patients beyond the Milan criteria were also beyond the University of California San Francisco criteria (UCSF) criteria. Preoperative ablative therapy for HCC was done in 22 patients (35.5 %), four patients had complete ablation with no residual tumor tissues. Microvascular invasion was present in ten patients (16 %) in histopathological study. Seven (11.3 %) patients had recurrent HCC post transplantation. The 1, 3, 5 years total survival was 88.7, 77.9, 67.2 %, respectively, while the tumor-free survival was 87.3, 82.5, 77.6 %, respectively. Expansion of selection criteria beyond Milan and UCSF had no increased risk effect on recurrence of HCC but had less survival rate than patients within the Milan criteria. Microvascular invasion was an independent risk factor for tumor recurrence. 相似文献

In this retrospective study of hepatitis C virus (HCV)-infected transplant recipients in the 9-center Adult to Adult Living Donor Liver Transplantation Cohort Study, graft and patient survival and the development of advanced fibrosis were compared among 181 living donor liver transplant (LDLT) recipients and 94 deceased donor liver transplant (DDLT) recipients. Overall 3-year graft and patient survival were 68% and 74% in LDLT, and 80% and 82% in DDLT, respectively. Graft survival, but not patient survival, was significantly lower for LDLT compared to DDLT (P = 0.04 and P = 0.20, respectively). Further analyses demonstrated lower graft and patient survival among the first 20 LDLT cases at each center (LDLT 20; P = 0.002 and P = 0.002, respectively) and DDLT recipients (P < 0.001 and P = 0.008, respectively). Graft and patient survival in LDLT >20 and DDLT were not significantly different (P = 0.66 and P = 0.74, respectively). Overall, 3-year graft survival for DDLT, LDLT >20, and LDLT 20 were not significantly different. Important predictors of graft loss in HCV-infected patients were limited LDLT experience, pretransplant HCC, and higher MELD at transplantation. 相似文献

Objective
Living donor liver transplantation (LDLT) may represent a valid therapeutic option allowing several advantages for patients affected by hepatocellular carcinoma (HCC) awaiting orthotopic liver transplantation (OLT). However, some reports in the literature have demonstrated worse long-term and disease-free survivals among patients treated by LDLT than deceased donor liver transplantation (DDLT) for HCC. Herein we have reported our long-term results comparing LDLT with DDLT for HCC.Patients and Methods
Among 179 patients who underwent OLT from January 2000 to December 2007, 25 (13.9%) received LDLT with HCC 154 (86.1%) received DDLT. Patients were selected based on the Milan criteria. Transarterial chemoembolization, radiofrequency ablation, percutaneous alcoholization, or liver resection was applied as a downstaging procedure while on the waiting list. Patients with stage II HCC were proposed for LDLT.Results
The overall 3- and 5-year survival rates were 77.3% and 68.7% versus 82.8% and 76.7% for LDLT and DDLT recipients, respectively, with no significant difference by the log-rank test. Moreover, the 3- and 5-year recurrence-free survival rates were 95.5% and 95.5% (LDLT) versus 90.5% and 89.4% (DDLT; P = NS).Conclusions
LDLT guarantees the same long-term results as DDLT where there are analogous selection criteria for candidates. The Milan criteria remain a valid tool to select candidates for LDLT to achieve optimal long-term results. 相似文献16.
BACKGROUND: The development of living donor liver transplantation has stimulated discussion about the expansion of tumor burden limits for patients with hepatocellular carcinoma (HCC). Although serum alphafetoprotein (AFP) level is an important predictor of tumor recurrence, it is not included in the existing selection criteria for HCC in transplantation. METHODS: We performed a retrospective study of 63 consecutive adults with HCC diagnosed preoperatively who received living donor liver transplantation from February 1999 to September 2005 and survived over 1 month. The authors devised new scoring criteria that included tumor size, tumor number, and pretransplant AFP level as prognostic factors. The score of each parameter was classified from 1 to 4 points (tumor size, < or =3, 3.1 to 5, 5.1 to 6.5, >6.5 cm; tumor number, 1, 2 or 3, 4 or 5, or > or =6 nodules; and AFP, < or =20, 20.1 to 200, 200.1 to 1000, >1000 ng/mL, respectively). We defined that 3 to 6 points and 7 to 12 points were "transplantable" and "nontransplantable," respectively. The usefulness of the devised criteria was then investigated as a method of selecting candidates with HCC for transplantation. RESULTS: The candidates' overall 3-year survival rate and recurrence-free survival rate were 67% and 70% after transplantation, respectively. Based on pretransplant imaging, 37 (59%), 41 (65%), and 44 (70%) of the 63 patients met the Milan criteria, University of Californica, San Francisco (UCSF) criteria, and the new scoring criteria. Their 3-year survival rates were 80%, 78%, and 79%, respectively. Moreover, based on posttransplant data, the scoring criteria correlated with the risk of death and HCC recurrence (Milan criteria, P = .005 and .001; UCSF criteria, P = .013 and .001 for death and recurrence; scoring criteria, P < .001 for both). CONCLUSIONS: The newly devised scoring criteria could expand usefully current selection criteria for transplantation without detrimentally affecting outcome in the living donor transplantation setting for HCC. 相似文献

Hepatocellular carcinoma (HCC) represents an increasing fraction of liver transplant indications; the role of living donor liver transplant (LDLT) remains unclear. In the Adult‐to‐Adult Living Donor Liver Transplantation Cohort Study, patients with HCC and an LDLT or deceased donor liver transplant (DDLT) for which at least one potential living donor had been evaluated were compared for recurrence and posttransplant mortality rates. Mortality from date of evaluation of each recipient's first potential living donor was also analyzed. Unadjusted 5‐year HCC recurrence was significantly higher after LDLT (38%) than DDLT (11%), (p = 0.0004). After adjustment for tumor characteristics, HCC recurrence remained significantly different between LDLT and DDLT recipients (hazard ratio (HR) = 2.35; p = 0.04) for the overall cohort but not for recipients transplanted following the introduction of MELD prioritization. Five‐year posttransplant survival was similar in LDLT and DDLT recipients from time of transplant (HR = 1.32; p = 0.27) and from date of LDLT evaluation (HR = 0.73; p = 0.36). We conclude that the higher recurrence observed after LDLT is likely due to differences in tumor characteristics, pretransplant HCC management and waiting time. 相似文献

Objective
Patients with hepatocellular carcinoma (HCC) exceeding the University of California, San Francisco (UCSF) criteria are normally rejected for cadaveric liver transplants. However, whether they should be allowed to undergo living donor liver transplantation (LDLT) has been controversial. We reviewed the outcome of patients with advanced HCC who underwent LDLT at our center.Methods
From April 2002 to May 2011, 176 patients underwent LDLT at our center; of these, 77 (44%) had HCC at the explant liver. Patient overall survival and recurrence-free survival (RFS) was analyzed using Kaplan-Meier method. Multivariate analysis was performed by Cox analysis.Results
Age was 56 ± 1 (56, 29-71) years; 62 (80.5%) were male; Model for End-stage Liver Disease Score was 11 ± 1 (9, 6-36), alpha fetoprotein (AFP) was 3683 ± 2019 (69, 3-139,591) ng/L; maximum tumor size was 4.5 (0.5-15) cm. Number or tumor nodules was 5 (1-10), and 32 (42%) had macrovascular invasion diagnosed pretransplant. Eleven (14%) were within UCSF criteria. After follow-up of 953 ± 90 (744, 2-2989) days, 53 (69%) were alive and 48 (62%) were recurrence-free. One-, 3- and 5-year overall survival (OS) and recurrence-free survival (RFS) were 80%, 70%, and 57% and 80%, 65%, and 48%, respectively. Five-year OS and RFS for those within UCSF criteria were both 78% versus 55% and 46% outside UCSF criteria (P = not significant). At multivariate analysis, high AFP, younger age, and macrovascular invasion were associated with both poor RFS.Conclusion
In HCC patients exceeding UCSF criteria, a reasonable 5-year overall survival of 55% post-LDLT can be obtained. Patients with HCC exceeding the UCSF criteria, especially in the older age group with no portal vein invasion and lower AFP level, should be actively considered for LDLT. 相似文献20.

We have proposed risk factors for tumor recurrence, such as tumor nodule ≥5 cm and des-gamma-carboxy prothrombin ≥300 mAU/mL after living donor liver transplantation (LDLT) for hepatocellular carcinoma (HCC). The aim of this study was to clarify the risk factors for HCC recurrence and mortality within our criteria. We enrolled 152 adult recipients who had undergone LDLT for end-stage liver disease with HCC who met our criteria. The recurrence-free survival rates after LDLT were calculated. Risk factors for tumor recurrence were identified. On univariate analysis, factors affecting recurrence-free survival were pretransplant treatment for HCC, neutrophil-to-lumphocyte ratio (NLR) >4, alpha-fetoprotein ≥400 ng/mL, ≥5 nodules, and bilobar tumor distribution. Multivariate analysis identified that NLR >4 and ≥5 nodules were independent risk factors for tumor recurrence after LDLT (P = .003 and P = .002, respectively). Two-step selection criteria enable selection of patients who have high-risk of tumor recurrence. 相似文献
