Liver Transplantation for Recurrent Hepatocellular Carcinoma on Cirrhosis After Liver Resection: University of Bologna Experience

Liver resection (LR) for patients with small hepatocellular carcinoma (HCC) with preserved liver function, employing liver transplantation (LT) as a salvage procedure (SLT) in the event of HCC recurrence, is a debated strategy.
From 1996 to 2005, we treated 227 cirrhotic patients with HCC transplantable: 80 LRs and 147 LTs of 293 listed for transplantation. Among 80 patients eligible for transplantation who underwent LR, 39 (49%) developed HCC recurrence and 12/39 (31%) of these patients presented HCC recurrence outside Milan criteria. Only 10 of the 39 patients underwent LT, a transplantation rate of 26% of patients with HCC recurrence.
According to intention-to-treat analysis of transplantable HCC patients who underwent LR (n = 80), compared to all those listed for transplantation (n = 293), 5-year overall survival was 66% in the LR group versus 58% in patients listed for LT, respectively (p = NS); 5-year disease-free survival was 41% in the LR group versus 54% in patients listed for LT (p = NS).
Comparable 5-year overall (62% vs. 73%, p = NS) and disease-free (48% vs. 71%, p = NS) survival rates were obtained for SLT and primary LT for HCC, respectively.
LR is a valid treatment for small HCC and in the event of recurrence, SLT is a safe and effective procedure.     

Survival Benefit of Transplantation for Recurrence of Hepatocellular Carcinoma After Liver Resection

Background

Liver transplantation (LT) for hepatocellular carcinoma (HCC) can be used for tumor recurrence after liver resection (LR) both for initially transplant-eligible patients as conventional salvage therapy (ST) and for non–transplant-eligible patients (beyond Milan criteria) with a goal of downstaging (DW). The aim of this study was to compare the intention-to-treat (ITT) survival rates of patients who are listed for LT, according to these two strategies.

Methods

We analyzed a prospective database of 399 consecutive patients who underwent hepatic resection for HCC from 2002 to 2011 to identify patients included in the waiting list for tumor recurrence. Intention-to-treat (ITT) survivals were compared with those of patients resected for HCC within and beyond Milan criteria in the same period and not included in the LT waiting list.

Results

The study group consisted of 42 patients, 28 in the ST group (within Milan) and 14 in the DW group (beyond Milan). The 5-year ITT survival rate was similar between the 2 groups, being 64% for ST and 60% for DW (P = .84). Twenty-five patients (15 ST and 10 DW) underwent LT, 13 (10 ST and 3 DW) were still awaiting LT, 4 (3 ST and 1 DW) dropped out of the waiting list because of tumor progression, and 7 (5 ST [33%] and 2 DW [20%]) had tumor recurrence. The 5-year ITT survival of ST patients was similar to that of 252 in-Milan HCC patients resected only (P = .3), whereas 5-year ITT survival of DW patients was significantly higher (P < .01) than that of 105 beyond-Milan HCC patients resected only.

Conclusions

LR seems to be a safe and effective therapy both as alternative to transplantation and as downstaging strategy for intermediate-advanced HCC. The survival benefit of salvage LT, however, seems to be higher in the 2nd than in the 1st group.

Abstract：

Objective To summarize the experience with salvage liver transplantation for patients with recurrent hetaptocellular carcinoma(HCC)after primary liver resection.Methods From 2004 to 2008,376 patients with HCC received liver transplantation in our single center.Among these patients,36 (9.6 %)underwent salvage liver transplantation after primary liver curative resection due to intrahepatic recurrence.There were 29 males and 7 females with the mean age of 46 years old.Sixteen received right lobectomy,10 received left lobectomy and the others received sectionectomy or segmentectomy.As a control group for comparison,we used clinical data of the 147 patients who underwent primary OLT for HCC within Milan Criteria.Results The mean interval between initial liver resection and salvage transplantation was 34.9±16.2 months(1-63 months).Intraoperative bleeding volume,transfusion volume and operative time in the salvage group were significantly different from those in control group (P<0.05).There were no significant difference in post-operative complications,tumor recurrence rate,survival rate and tumor-free survival between these two groups(P>0.05).Conclusion In comparison with primary OLT,although salvage liver transplantation would increase the operation difficulties,it still remains a good option for patients with HCC recurrence after curative resection.     

Risk-Based Long-Term Screening for Hepatocellular Carcinoma Recurrence After Living Donor Liver Transplantation

Background

This study sought to establish an actual risk-based long-term screening protocol for hepatocellular carcinoma (HCC) recurrence after liver transplantation (OLT).

Methods

The study was a retrospective review of medical records from 334 HCC patients who underwent primary living donor OLT and followed up for at least 5 years.

Results

Overall 10-year patient survival rate was 67.5%, with a 4.8% perioperative mortality. HCC recurred in 68/318 (21.4%) surviving patients over a mean follow-up of 77 months. HCC recurrence was 20.7% at 5 and 22.2% at 10 years. Annual recurrence rates were 11.4%, 6.6%, and 2.0% during the first, second, and third years, respectively. Among patients within Milan criteria, the annual incidence of HCC recurrence was highest during the first 3 years; thereafter only 6 sporadic recurrences were observed during next 8 years. Among subjects beyond Milan criteria, recurrence was common during, but not after 3 years. In 43 patients (63.2%) increased alpha-fetoprotein (AFP) was an initial indication to perform further imaging studies to diagnosis recurrence, whereas they were detected incidentally on protocol screening imaging among another 25 patients (36.8%) in the absence of an AFP rise. There was a close correlation between pretransplant AFP level and AFP increase after HCC recurrence.

Conclusions

Patients beyond the Milan criteria require frequent tumor marker tests and imaging studies over the first 3 years; and those within Milan criteria require 10-years to follow-up primarily with tumor marker tests.     

Predictors of Outcome of Living Donor Liver Transplantation for Hepatocellular Carcinoma

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.     

Liver transplantation is an alternative treatment of hepatocellular carcinoma beyond the Milan criteria

Background

The decision to perform liver transplantation (LT) or liver resection (LR) for patients with hepatocellular carcinoma (HCC) who are beyond the Milan criteria remains controversial.

Methods

We retrospectively analyzed outcome data for 179 patients with HCC beyond the Milan criteria who were treated with LR (n = 135) or LT (n = 44). Univariate and multivariate Cox proportional hazard models were established. Kaplan-Meier survival curves were generated, and a log-rank test was performed to compare group survival status.

Results

Patients who underwent LR group were significantly older, had a lower TNM stage, and were more likely to have unilateral disease and noncirrhotic liver. Significantly more patients in the LR group had recurrence (53.3% vs 29.5%) or died (61.5% vs 43.2%) than patients in the LT group. Recurrence-free survival rates were 11.9% for the LR group and 61.5% for the LT group. The median overall survival duration showed no statistically difference between the LR group (28.0 months) and the LT group (50.0 months).

Conclusions

LT may be the better choice for patients with HCC beyond the Milan criteria.     

Liver transplantation criteria for hepatocellular carcinoma should be expanded: a 22-year experience with 467 patients at UCLA

OBJECTIVE: To assess the efficacy of orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC) and the impact of current staging criteria on long term survival. SUMMARY BACKGROUND DATA: HCC is becoming an increasingly common indication for OLT. Medicare approves OLT only for HCCs meeting the Milan criteria, thus limiting OLT for an expanding pool of potential liver recipients. We analyzed our experience with OLT for HCC to determine if expansion of criteria for OLT for HCC is warranted. METHODS:: All patients undergoing OLT for HCC from 1984 to 2006 were evaluated. Outcomes were compared for patients who met Milan criteria (single tumor < opr =5 cm, maximum of 3 total tumors with none >3 cm), University of California, San Francisco (UCSF) criteria (single tumor <6.5 cm, maximum of 3 total tumors with none >4.5 cm, and cumulative tumor size <8 cm), or exceeded UCSF criteria. RESULTS: A total of 467 transplants were performed for HCC. At mean follow up of 6.6 +/- 0.9 years, recurrence rate was 21.2%, and overall 1, 3, and 5-year survival was 82%, 65%, and 52%, respectively. Patients meeting Milan criteria had similar 5-year post-transplant survival to patients meeting UCSF criteria by preoperative imaging (79% vs. 64%; P = 0.061) and explant pathology (86% vs. 71%; P = 0.057). Survival for patients with tumors beyond UCSF criteria was significantly lower and was below 50% at 5 years. Multivariate analysis showed that tumor number (P < 0.001), lymphovascular invasion (P < 0.001), and poor differentiation (P = 0.002) independently predicted poor survival. CONCLUSIONS: This largest single institution experience with OLT for HCC demonstrates prolonged survival after liver transplantation for tumors beyond Milan criteria but within UCSF criteria, both when classified by preoperative imaging and by explant pathology. Measured expansion of OLT criteria is justified for tumors not exceeding the UCSF criteria.     

An Analysis of Resection vs Transplantation for Early Hepatocellular Carcinoma: Defining the Optimal Therapy at a Single Institution

Background The reported survival after liver transplantation (OLT) for early hepatocellular carcinoma (HCC) is superior to the results of liver resection (LR), but few analyses have considered long waiting times and patient drop-offs due to tumor progression. Methods From 1995–2005, 347 patients with HCC were evaluated at our institution and underwent either LR (n = 174) or placed on the OLT waiting list (n = 173). Patients who only underwent ablation were not included. After eliminating patients with 1) incidental tumors after OLT, 2) tumors outside of Milan criteria, 3) preoperative vascular invasion prior to LR and 4) Child-Pugh Class C cirrhosis prior to OLT, 261 patients (LR = 121; OLT = 140) were included in this analysis. Results Median follow-up time was 35 months. Median waiting time for OLT was 7.7 months; during this time, 30 patients were taken off the waiting list. Overall survival (OS) from time of listing or LR was not different between the two groups; 1, 3, and 5 year OS after LR was 89%, 75%, and 56% compared with 90%, 70%, and 64% for OLT (P = .84). Only patients who waited <4 months for OLT (n = 67) had better survival than those who underwent LR (P = .05). Patients who waited longer that four months for OLT had a 2.5× higher risk of death in a Cox multivariate model [odds ratio (OR) 2.5; 95% confidence interval (CI): 1.3–5; P = .007]. Conclusion Unless waiting time is short (<4 months), the survival of patients with early HCC is similar between LR and LT.

Management of Hepatocellular Carcinoma Recurrence After Liver Transplantation

Management of patients with hepatocellular carcinoma (HCC) recurrence after liver transplantation (OLT) is not well established. We conducted a retrospective analysis of our results in the treatment of HCC recurrence after OLT Patients. The 23 HCC recurrences developed after 182 OLT performed for HCC within Milan criteria, had an average follow-up of 60 months.

Results

The median time to recurrence was 23.4 months. Surgical resection of the recurrence was possible in 11 patients, but an R-0 resection was obtained in 8 patients. Four of these 8 patients developed another recurrence, with 3 succumbing due to tumor recurrence and 1 alive at 12 months with recurrence. The other 4 patients without recurrences, include 3 who are alive at 19, 31, and 86 months and 1 who died at 32.6 months due to hepatitis C recurrence. The 3 patients with palliative resections developed recurrences. Twelve patients were rejected for surgery: 8 were treated symptomatically, 2 with systemic chemotherapy, and 2 with everolimus and sorafenib. This last treatment was also prescribed for 2 patients after R-0 surgery who are alive at 19 and 31 months and for 1 patient after R-1 surgery who is alive at 19 months. Of 15 patients who died, 13 succumbed to HCC recurrence. The average survival from transplantation was 61.7 ± 37.5 and 48 ± 34.3 months for patients without and with recurrence, respectively (P < .001). The survival from the recurrence was significantly higher among patients with R-0 surgery: 32.3 ± 21.5 versus 11.9 ± 6.9 months (P = .006).

Conclusions

HCC recurrence after OLT of patients within Milan criteria was low but had a great impact on survival. Few cases are amenable to R-0 resection, but when possible it was associated with a significantly increased survival, although with an high incidence of a new recurrence. There is a rationale for the use of sorafenib and mammalian target of rapamycin based immunosuppression, which warrants randomized studies.

Impact of Tumor Characteristic on the Outcome of Liver Transplantation in Patients With Hepatocellular Carcinoma

Introduction

Orthotopic liver transplantation (OLT) is a well-established treatment for cirrhotic patients with hepatocellular carcinoma (HCC) who meet the Milan criteria. The aim of this study was to identify predictors of survival among 65 patients with HCC in cirrhotic livers who underwent liver transplantation (OLT).

Methods

From January 2001 to December 2008, we performed 655 OLT in 615 patients. HCC was diagnosed in 58 patients before OLT and in 65 by histological examination of the explanted livers; 74% of the patients met Milan criteria by histological examination.

Results

The median follow-up was 27 months (range = 1-96). We analyzed patient age and gender, etiology of liver disease, Child score at transplantation, rejection episodes, tumor number/size, vascular invasion, and differentiation grade. There was no significant difference in survival among patients grouped according to the Model for End-stage Liver Disease staging system for HCC. The 5-year survival of patients with low differentiated (G3) HCC was significantly worse than that of those with moderately differentiated (G2) or well-differentiated (G1) HCC: 50%, 81%, and 86% respectively, (P < .01). Patients with microvascular invasion displayed a worse 5-year survival than those without vascular invasion (42% vs 80%; P < .01).

Conclusions

The analysis indicated that the histological grade of the tumors and evidences of microscopic vascular invasion were the most useful predictive factors for overall survival among patients with cirrhosis after liver transplantation for HCC.     

Treatment of Hepatocellular Carcinoma With Liver Transplantation: A Single-Center Experience From Brazil

Introduction

Orthotopic liver transplantation (OLT) is the treatment of choice of hepatocellular carcinoma (HCC) for patients with cirrhosis, mainly those with early HCC. Herein we have present the clinical characteristics and outcomes of cirrhotic patients with HCC who underwent OLT from cadaveric donors in our institution.

Methods

From May 2001 to May 2009, we performed 121 OLT including 24 patients (19.8%) with cirrhosis and HCC within the Milan criteria. In 4 cases, HCC was an incidental finding in the explants.

Results

The patients' average age was 55 ± 10 years, including 82% men. Fifty percent of patients were Child class B or C. The average Model for End Stage Liver Disease for Child A, B, and C categories were 11, 15, and 18, respectively. The HCC diagnosis was made by 2 dynamic images in 16 cases; 1 dynamic image plus alphafetoprotein >400 ng/mL in 4; and 4 by histologic confirmation. Twenty patients received a locoregional treatment before OLT: 6 percutaneous ethanol injection, 9 transarterial chemoembolization, 1 transarterial embolization, and 4 a combination of these modalities. The median follow-up after OLT was 19.7 months (range, 1-51). A vascular invasion was observed in the explant of 1 patient, who developed an HCC recurrence and succumbed at 8 months after OLT. Two further patients, without vascular invasion or satellite tumor displayed tumor recurrences at 7 and 3 months after OLT, and death at 2 and 1 month after the diagnosis. The remaining 25 patients have not shown a tumor recurrence.

Conclusion

In the present evaluation, OLT patients with early HCC and no vascular invasion showed satisfactory results and good disease-free survival. Strictly following the Milan criteria for liver transplantation in patients with HCC greatly reduces but does not completely avoid, the chances of tumor recurrence.

Hepatocellular Carcinoma and Liver Transplantation: A 12-Year Experience

Background

Orthotopic liver transplantation (OLT) for patients with cirrhosis and concomitant hepatocellular carcinoma (HCC) in early stages is the treatment of choice, with an acceptable recurrence rate and excellent survival.

Aim

We sought to evaluate (1) the accuracy of preoperative imaging; (2) the impact of pre-OLT treatments on survival and recurrence; and (3) the influence of beyond Milan criteria selection on global outcomes.

Methods

We studied a cohort of 65 patients with HCC among 300 consecutive OLTs over a single 12-year experience. We analyzed the overall outcomes of survival and recurrence, the accuracy of preoperative diagnosis and staging the influence of neoadjuvant treatment prior to OLT, and the effect on overall outcomes beyond the Milan criteria in our series.

Results

The 65 transplants were performed for HCC, mostly in association with hepatitis C virus and alcoholic cirrhosis with HTP. At a mean follow-up of 40.32 months, the recurrence rate was 5.7% among the 61 HCC confirmed by histopathology. The overall survival was 30.07. Actuarial survivals at 1, 5, and 10 years were 82%, 77%, and 62%, respectively. Six retransplants occurred among the seven graft losses albeit with poor survival after the second graft. Most explants showed low pTNM stages with favorable microscopic features. Preoperative imaging tests failed to achieve an accurate diagnosis in 15.38% of the series. The role of alpha-fetoprotein (AFP) and hepatic biopsy was irrelevant. Unfavorable histopathologic factors predicted a greater recurrence rate, but had no influence on survival. Neither recurrence nor survival were modified by pre-OLT therapy.

Conclusions

In our series, AFP, hepatic biopsy, and pre-OLT treatment had limited roles. Radiological imaging techniques underestimated HCC staging and lead to a misdiagnosis to an expected degree. Despite these findings, this single institution experience with OLT for HCC showed excellent survivals with a low recurrence rate including cases of patients beyond the Milan criteria.     

Resection for hepatocellular carcinoma is a good option in Child-Turcotte-Pugh class A patients with cirrhosis who are eligible for liver transplantation.

The best treatment option for patients with single, early hepatocellular carcinoma (HCC) and cirrhosis, good liver function, and absence of portal hypertension remains to be established. The aim of this work was to compare the outcome of liver resection (LR) with that of liver transplantation (LT) for single, early HCC in Child-Turcotte-Pugh class A patients with cirrhosis younger than 70 years of age. Thirty-seven of 134 patients who underwent LR and 36 of 125 who underwent LT for HCC in our unit fulfilled the inclusion criteria. No differences were observed in mean tumor size (3 cm); HCV cirrhosis predominated in the LT group and older age in the LR group. Postoperative mortality was higher and hospital stay longer in the LT group. Patient survival was similar in both groups. Tumor recurrence was higher in the LR group (59% vs. 11%), extrahepatic recurrences predominated after LT and hepatic recurrences after LR. Disease-free survival was significantly better after LT. Eighteen patients presented hepatic recurrence after LR: 5 advanced and 13 early. Seventeen patients--13 with early HCC recurrence and 4 with liver failure--were potential candidates for salvage LT. However, 10 of 17 patients were older than 70 years at this time. Salvage LT could only be performed in 6 patients: 5 for HCC recurrence and 1 for liver failure. Results of salvage LT were similar to those of primary LT. In conclusion, only 27.6% of resected patients were eligible for LT. LR is a good option since it offers similar survival to LT. Salvage liver transplantation was performed in 16.2% of resected patients, with older age being the main contraindication. Outcome of salvage LT was similar to that of primary LT.     

Recurrence rate and transplantability after liver resection in patients with hepatocellular carcinoma who initially met transplantation criteria

To understand the recurrence rate and transplantability after liver resection (LR), which are essential factors to predict the prognosis of initial resection and salvage transplantation for hepatocellular carcinoma (HCC), we reviewed the clinical records of 279 consecutive HCC patients who met the Milan criteria and underwent LR between 1990 and 2000. Recurrence-free survival rates after 1, 2, 3, 5, and 10 years following LR were 84%, 62%, 49%, 29%, and 17%, respectively. Multivariate analysis using clinical factors such as age, sex, histological differentiation, serum levels of alpha-fetoprotein and 7S domain of type IV collagen (7S collagen), platelet counts, indocyanin green retention test after 15 minutes, and type of LR (resection of one or more segments, or less than one segment) revealed 7S collagen to be a independent factor that significantly affects recurrence-free survival. Yearly recurrence rates up to 5 years after resection ranged from 14% to 27%, averaging 20%. Concerning 169 patients who underwent tests for 7S collagen, the average yearly recurrence rate (27%) in patients with 7S collagen levels 8.0 ng/mL or higher was remarkably greater than that in the patients with levels less than 8.0 ng/mL (16%). The transplantability rate at the time of recurrence meeting the Milan criteria was roughly 60%. There were no pre-LR factors that significantly predicted transplantability. This result indicates that patients with lower 7S collagen levels are more eligible for initial LR and then salvage LT rather than primary LT.     

Hepatic Resection for Hepatocellular Carcinoma Meeting Milan Criteria in Child-Turcotte-Pugh Class A Patients With Cirrhosis

This study evaluated whether hepatic resection is a reasonable strategy as an initial treatment for hepatocellular carcinoma (HCC) meeting Milan criteria in patients with compensated cirrhosis. From the database of 435 consecutive patients with resection of HCC between July 1994 and May 2007, 213 patients were found to have Child-Turcotte-Pugh class A cirrhosis and HCC meeting Milan criteria, as shown by preoperative image studies. We examined long-term survivals and patterns of recurrence after hepatic resection among those patients. Overall survival rates at 1, 3, 5, and 10 years were 92%, 78%, 69%, and 52%, respectively, and 1-, 3-, 5-, and 10-year disease-free survival rates were 79%, 57%, 44%, and 19%, respectively. Pathological review indicated that 36/213 patients (16.9%) had another nodule and/or gross vascular invasion. Microvascular invasion, tumor size, and histological grade of cirrhosis were independent risk factors for recurrence. Sixty percent of recurrent cases met the Milan criteria. The six patients who underwent living donor salvage liver transplantation (OLT) for intrahepatic recurrence were alive without recurrence at a median of 24 (range = 8-31) months. These favorable data suggest that hepatic resection is a good option for small HCCs in patients with compensated cirrhosis; and salvage OLT may be reserved for patients with recurrences.     

Salvage Liver Transplantation for Recurrent Hepatocellular Carcinoma After Liver Resection: Feasibility of the Milan Criteria and Operative Risk

Introduction

Although the Milan criteria are widely accepted for liver transplantation (OLT) for hepatocellular carcinoma (HCC), they have not been fully evaluated as feasible for salvage liver transplantation (SLT) of recurrent HCC after hepatic resection. The operative difficulties of SLT increase the operative risk. The aim of this study was to evaluate the feasibility of the Milan criteria for SLT and its operative complications.

Patients and methods

From March 2005 to November 2007, 46 HCC patients received OLT including 15 SLTs after prior partial hepatectomy (SLT group) and 31 primary OLTs (PLT group).

Results

There was no postsurgical hospital mortality among the SLT group but one case in the PLT group due to pneumonia followed by sepsis. There was no difference in the incidence of surgical complications between the two groups. Overall survival rates of SLT group patients were similar to those of the PLT group (P = .14), especially comparing both groups of patients within the Milan criteria (P = .89). There was no recurrence of HCC among the patients within the Milan criteria.

Conclusions

SLT is a feasible procedure for recurrent HCC meeting the Milan criteria; the operative risk of the SLT is also acceptable.     

Results of resection and transplantation for hepatocellular carcinoma in cirrhosis and noncirrhosis

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide. Both liver resection (LR) and orthotopic liver transplantation (OLT) are surgical treatment options depending on the size of the tumor and the presence of cirrhosis. Liver cirrhosis is the main reason for the high early postoperative mortality after resection. Even in the Child A stage, extensive resections are not recommended. This study presented the results of surgical treatment (LR or OLT) for HCC in cirrhotic and noncirrhotic livers. We analyzed the data of 76 patients who underwent LR or OLT for HCC from January 2001 to December 2006. In noncirrhotic livers the following resections were performed: 30 right and extended right hemihepatectomies (54.5%); 11 left hemihepatectomies (20%); and 14 mono- or bisegmentectomies (25.5%). In cirrhotic livers the following procedures were performed: in Child A stage 1 right hemihepatectomy, 1 extended right hemihepatectomy, 1 extended left hemihepatectomy, and 4 mono- or bisegmentectomies; and in Child B stage, 3 mono- or bisegmentectomies. Among 11 patients who underwent transplantation, tumors in 2 patients exceeded the Milan criteria. Five patients in the LR group were treated with transarterial chemoembolization before transplantation. LR for HCC in cirrhosis should be performed with caution; there were no long-term survivors in our data. Our study confirmed that OLT shows good long-term survival in early HCC stages. However, this may also be true for stages above the Milan criteria. For HCC in noncirrhotic livers, LR remains the treatment of choice, justifying an extensive surgical approach. Such an approach achieved favorable long term survivals.     

Liver Transplantation Results for Hepatocellular Carcinoma in Chile

Hepatocellular carcinoma (HCC) is the most common malignant tumor of the liver. Liver transplantation is the best treatment for HCC; it improves survival, cures cirrhosis, and abolishes local recurrence. We describe the outcomes of patients with HCC who underwent liver transplantation in two liver transplantation centers in Chile.

Methods

This study is a clinical series elaborated from the liver transplantation database of Pontificia Universidad Católica and Clínica Alemana between 1993 and 2009. The survival of patients was calculated using the Kaplan-Meier survival analysis. The significant alpha level was defined as <.05.

Results

From 250 liver transplantations performed in this period, 29 were due to HCC. At the end of the study, 25 patients (86%) were alive. The mean recurrence-free survival was 30 months (range 5 months to 8 years). The 5-year survival for patients transplanted for HCC was >80%; however, the 5-year overall survival of patients who exceeded the Milan criteria in the explants was 66%. There was no difference in overall survival between patients transplanted for HCC versus other diagnosis (P = .548).

Conclusion

This series confirmed that liver transplantation is a good treatment for patients with HCC within the Milan criteria.
