Feasibility of salvage liver transplantation for patients with recurrent hepatocellular carcinoma

BACKGROUND: Recurrence is the most frequent cause of treatment failure after hepatocellular carcinoma (HCC) resection. Salvage liver transplantation is an alternative treatment for recurrent HCC. The transplantability for patients with recurrent HCC has not been well studied. STUDY DESIGN: This study sought to determine how many patients with recurrent HCC are still candidates for liver transplantation, and to ascertain the possible time from HCC recurrence to the loss of transplantability. In an university hospital setting, 154 of the 252 patients receiving primary HCC resection, from January 1992 through December 1996, had recurrence and were analyzed. The mean follow-up time was 6 years. Among the 154 patients, 74 patients (group 1) were not eligible for liver transplantation according to the Milan criteria, while 80 patients were eligible (group 2). Demographic characteristics of both groups were compared and the curve of transplantability was calculated. RESULTS: When compared with group 1 patients, group 2 patients displayed more cirrhosis (p = 0.007), lower pTNM stage (p = 0.004), were older (p = 0.004), presented with smaller tumors (p < 0.001), and displayed a longer disease-free interval (p < 0.001). In group 1, only 47% (35/74) patients were eligible for liver transplantation at the time of index hepatectomy, in contrast to 84% (67/80) in the group 2 patients, p < 0.001. The median time from HCC recurrence to the time they were no longer transplantable was 38 months. The total time from the index HCC resection to the time of loss of transplantability was 83 months. CONCLUSION: In a cohort of patients after resection for their primary HCC, 33% patients had no recurrence and were not in need for liver transplantation in a mean follow-up of 72 months. About 52% of the patients with recurrent HCC still meet the criteria for liver transplantation. For patients with some certain characteristics, resection of the primary HCC may postpone the time of liver transplantation and prolong the time in which a suitable donor searched, while primary liver transplantation may be considered for those patients with factors of low transplantability after recurrence.     

Long-term survival and pattern of recurrence after resection of small hepatocellular carcinoma in patients with preserved liver function: implications for a strategy of salvage transplantation

OBJECTIVE: To evaluate the survival results and pattern of recurrence after resection of potentially transplantable small hepatocellular carcinomas (HCC) in patients with preserved liver function, with special reference to the implications for a strategy of salvage transplantation. SUMMARY BACKGROUND DATA: Primary resection followed by transplantation for recurrence or deterioration of liver function has been recently suggested as a rational strategy for patients with HCC 5 cm or smaller and preserved liver function. However, there are no published data on transplantability after HCC recurrence or long-term deterioration of liver function after resection of small HCC in Child-Pugh class A patients. Such data are critical in determining the feasibility of salvage transplantation. METHODS: From a prospective database of 473 patients with resection of HCC between 1989 and 1999, 135 patients age 65 years or younger had Child-Pugh class A chronic liver disease (chronic hepatitis or cirrhosis) and transplantable small HCC (solitary < or =5 cm or two or three tumors < or = 3 cm). Survival results were analyzed and the pattern of recurrence was examined for eligibility for salvage transplantation based on the same criteria as those of primary transplantation for HCC. RESULTS: Overall survival rates at 1, 3, 5, and 10 years were 90%, 76%, 70%, and 35%, respectively, and the corresponding disease-free survival rates were 74%, 50%, 36%, and 22%. Cirrhosis and oligonodular tumors were predictive of worse disease-free survival. Patients with concomitant oligonodular tumors and cirrhosis had a 5-year overall survival rate of 48% and a disease-free survival rate of 0%, which were significantly worse compared with other subgroups. At a median follow-up of 48 months, 67 patients had recurrence and 53 (79%) of them were considered eligible for salvage transplantation. Decompensation from Child-Pugh class A to B or C without recurrence occurred in only six patients. CONCLUSIONS: For Child-Pugh class A patients with small HCC, hepatic resection is a reasonable first-line treatment associated with a favorable 5-year overall survival rate. A considerable proportion of patients may survive without recurrence for 5 or even 10 years; among those with recurrence, the majority may be eligible for salvage transplantation. These data suggest that primary resection and salvage transplantation may be a feasible and rational strategy for patients with small HCC and preserved liver function. Primary transplantation may be a preferable option for the subset of patients with oligonodular tumors in cirrhotic liver in view of the poor survival results after resection.     

Liver resection as a bridge to transplantation for hepatocellular carcinoma on cirrhosis: a reasonable strategy?

OBJECTIVE: To assess the viability of a strategy of primary resection with secondary liver transplantation (LT) for hepatocellular carcinoma (HCC) on cirrhosis. SUMMARY BACKGROUND DATA: LT is the optimal treatment of HCC with cirrhosis. Owing to organ shortage, liver resection is considered as a reasonable first-line treatment of patients with small HCC and good liver function, with secondary LT as a perspective in case of recurrence. The viability of such strategy, positively explored in theoretical models, is not documented in clinical practice. METHODS: Among 358 consecutive patients with HCC on cirrhosis treated by liver resection (n = 163; 98 of whom were transplantable) or transplantation (n = 195), the feasibility and outcome of secondary transplantation was evaluated in a 2-step fashion. First, secondary LT for tumor recurrence after resection (n = 17) was compared with primary LT (n = 195), to assess the risk and the outcome of secondary LT in patients who effectively succeeded to be treated by this approach. Second, primary resection in transplantable patients (n = 98) was compared with that of primary LT (n = 195) on an intention-to-treat basis, to assess the outcome of each treatment strategy and to determine the proportion of resected patients likely to be switched for secondary LT. Transplantability of resected patients was retrospectively determined according to selection criteria of LT for HCC. RESULTS: Operative mortality (< or =2 months) of secondary LT was significantly higher than that of primary LT (28.6% versus 2.1%; P = 0.0008) as was intraoperative bleeding (mean transfused blood units, 20.7 versus 10.5; P = 0.0001). Tumor recurrence occurred more frequently after secondary than after primary LT (54% versus 18%; P = 0.001). Posttransplant 5-year overall survival was 41% versus 61% (P = 0.03), and disease-free survival was 29% versus 58% (P = 0.003) for secondary and primary LT, respectively.Of 98 patients treated by resection while initially eligible for transplantation, only 20 (20%) were secondarily transplanted, 17 of whom (17%) for tumor recurrence and 3 (3%) for hepatic decompensation. Transplantability of tumoral recurrence was 25% (17 of 69 recurrences). Compared with primarily transplanted patients, transplantable resected patients had a decreased 5-year overall survival (50% versus 61%; P = 0.05) and disease-free survival (18% versus 58%; P < 0.0001), despite the use of secondary LT.On a multivariate analysis including 271 patients eligible for transplantation and treated by either liver resection or primary LT, liver resection alone (P < 0.0001; risk ratio [RR] = 3.27) or liver resection with secondary LT (P < 0.05; RR= 1.87) emerged as negative independent factors of disease-free survival as compared with primary LT. A number of nodules > 3 (P = 0.002; RR= 2.02) and a maximum tumor size exceeding 30 mm (P < 0.0001; RR=1.93) were also predictive of lower disease-free survival. CONCLUSIONS: LT after liver resection is associated with a higher operative mortality, an increased risk of recurrence, and a poorer outcome than primary LT. In addition, liver resection as a bridge to LT impairs the patient transplantability and the chance of long-term survival of cirrhotic patients with HCC. Primary LT should therefore remain the ideal choice of treatment of a cirrhotic patient with HCC, even when the tumor is resectable.     

Surgical treatment of hepatocellular carcinoma

There are two principal aspects to surgical treatment of hepatocellular carcinoma, hepatectomy and transplantation. Transplantation is a treatment of the tumor and the underlying liver disease. When discovered in a liver, hepatocellular carcinoma is often seen as a large tumor. Resection is indicated if there is no bilobar diffusion or metastasis. If the liver is , liver resection is contraindicated in case of liver failure or atrophy. In patients with no liver failure (Child-Pugh A), bi-segmentary resection can be proposed. In the long run, the causes of mortality after resection for hepatocellular carcinoma are mainly subsequent to tumor recurrence. Transplantation is a priori the best possible treatment for small sized hepatocellular carcinoma developing on a chronically ill liver. For several reasons, this option cannot however be proposed for all patients: limited number of liver grafts available, high operative mortality around 10%. In addition, the risk of recurrence of the causal liver disease, particularly in case of hepatitis B and C infections, is high. Finally, even if the initial tumor is a unique small-sized lesion, the risk of recurrence is favored by the immunosuppression required for tolerance after liver transplantation.

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.

Optimal Initial Treatment for Early Hepatocellular Carcinoma in Patients with Preserved Liver Function: Transplantation or Resection?

Partial hepatic resection has been the mainstay of curative treatment for hepatocellular carcinoma (HCC) in cirrhotic patients with preserved liver function. Liver transplantation for HCC was initially developed as a treatment option for patients with unresectable tumors associated with Child B or C cirrhosis. However, in recent years, some authors have advocated liver transplantation even for resectable early HCC associated with Child A cirrhosis. Whether transplantation or liver resection is the optimal initial treatment for early HCC in compensated cirrhosis depends on the survival results and also the availability of liver grafts. Recent studies comparing liver resection and transplantation for early HCC in Child A cirrhotic patients demonstrated similar long-term survival. While liver transplantation is associated with a lower tumor recurrence rate, this benefit is counteracted by long-term complications such as immunosuppression related infections and neoplasms. Patients put on transplantation waiting list run a significant risk of tumor progression and dropout, while liver resection is immediately applicable to all. A premature liver transplantation may expose patients to the side effects of immunosuppression earlier than necessary. With the current shortage of liver grafts, advocating primary liver transplantation for patients with early HCC associated with compensated cirrhosis will increase waiting time of transplantation and further increases the chance of dropout. Resection first and salvage transplantation for recurrent tumors or liver failure has been shown to be a feasible strategy in the majority of patients, and this appears to be the optimal strategy with the best use of organs.
