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

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 6 2008
M. Del Gaudio
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. [source]

Radiofrequency ablation of hepatic tumors: Lessons learned from 3000 procedures

JOURNAL OF GASTROENTEROLOGY AND HEPATOLOGY, Issue 10 2008
Hyunchul Rhim
Abstract Radiofrequency ablation has been accepted as the most popular local ablative therapy for unresectable malignant hepatic tumors. For 9 years from April 1999, we performed 3000 radiofrequency ablation procedures for hepatic tumors in our institution. Our results on the safety (mortality, 0.15%/patient) and therapeutic efficacy (5-year survival rate, 58%) are similar to those of previous studies reported, supporting the growing evidence of a clear survival benefit, excellent results for local tumor control and improved quality of life. The most important lesson learned from our 3000 procedures is that the best planning, safe ablation and complete ablation are key factors for patient outcome. Furthermore, multimodality treatment is the best strategy for recurrent hepatocellular carcinoma encountered after any kind of first-line treatment. [source]

Prognosis following non-surgical second treatment in patients with recurrent hepatocellular carcinoma after percutaneous ablation therapy

LIVER INTERNATIONAL, Issue 3 2009
Manabu Morimoto
Abstract Objective: The aims of this study were to identify prognostic factors in patients who received a non-surgical second treatment for the development of recurrent hepatocellular carcinoma (HCC) after an initial percutaneous ablation therapy. Methods: We retrospectively studied 147 patients with HCC who had received an initially successful percutaneous ablation therapy. The patients were followed up using computed tomography and/or ultrasound every 3 months and a second treatment was performed for subsequent recurrent tumours. Results: The 3- and 5-year survival rates of the 147 patients were 90 and 65% respectively. During a mean follow-up period of 33 months, local or distant tumour recurrences developed in 77 of the 147 patients, and the 3- and 5-year survival rates after a second treatment in these 77 patients were 73 and 44% respectively. Forty-six of the 77 patients with up to three recurrent tumours received percutaneous ablation therapy for the second treatment, and the remaining 31 patients with more than three (multiple) recurrent tumours received transcatheter arterial chemoembolization for their second treatment. A multivariate analysis revealed the serum ,-fetoprotein level at the time of the appearance of the recurrent HCC (<100 ng/ml vs ,100 ng/ml, P=0.009) and the number of recurrent tumours (up to three vs more than three, P=0.009) to be independent prognostic factors after the second treatment. Conclusions: The serum ,-fetoprotein level and recurrent tumour number were prognostic factors following the second treatment in patients with recurrent HCC who had received an initially successful ablation therapy.

Identifying risk for recurrent hepatocellular carcinoma after liver transplantation: Implications for surveillance studies and new adjuvant therapies

LIVER TRANSPLANTATION, Issue 7 2008
Edie Y. Chan
The recurrence of hepatocellular carcinoma (HCC) is a major cause of mortality for patients transplanted with HCC. There currently exists no standard method for identifying those patients with a high risk for recurrence. Identification of factors leading to recurrence is necessary to develop an efficient surveillance protocol and address new potential adjuvant therapies. We conducted a retrospective review of 834 consecutive liver transplants from 1/1/1996 to 12/31/2005 (mean follow-up 1303 ± 1069 days) at one institution and 352 consecutive transplants from 1/2/2002 to 12/31/2005 (mean follow-up 836 ± 402 days) at a second institution. The test cohort comprised patients identified with HCC in their explanted livers from 1/1/2001 to 12/31/2005 at the first institution. Explant pathology and donor and recipient characteristics were reviewed to determine factors associated with HCC recurrence. These predictors were validated in the remaining liver transplant recipients. The test cohort had 116 patients with findings of HCC in their explanted livers. Twelve patients developed recurrent HCC. Stepwise logistic regression identified 4 independent significant explant factors predictive of recurrence. Size of one tumor (>4.5 cm), macroinvasion, and bilobar tumor were positive predictors of recurrence, whereas the presence of only well-differentiated HCC was a negative predictor. Designating each significant factor with points in relation to its odds ratio, a Predicting Cancer Recurrence Score (PCRS) with results ranging from ,3 to 6 was developed that accurately determined risk of recurrence. These findings were then applied to the two validation cohorts, which confirmed the high predictive value of this model. In conclusion, patients transplanted for HCC with a PCRS of ,0 have a low risk of recurrence. Patients with a PCRS of 1 or 2 have a moderate risk of recurrence, and those with a PCRS of ,3 have a high risk for recurrence. Liver Transpl 14:956,965, 2008. © 2008 AASLD. [source]

Efficacy of repeat hepatic resection for recurrent hepatocellular carcinomas

ANZ JOURNAL OF SURGERY, Issue 10 2009

Abstract Background:, This study evaluated the efficacy of repeat hepatic resection for recurrent hepatocellular carcinoma (HCC) and the clinicopathological factors influencing overall survival after resection. Methods:, From 1992 to 2005, 231 patients underwent curative hepatic resection for HCC at Yokohama City University, Japan. Of these, 105 patients developed intrahepatic recurrence, and 24 repeat hepatectomies were performed for recurrent HCC. Survival data were analysed, and prognostic factors for repeat hepatic resection were determined. Results:, The overall cumulative 1-, 3- and 5-year survival rates and the median survival time of the patients after initial hepatic resection (n= 231) did not differ from those of the patients after repeat hepatic resection (n= 24), with values of 91.3, 70.2 and 49.1%, and 57 months, versus 91.7, 73.1 and 50.9%, and 61.5 months, respectively (P= 0.875). The operative time and blood loss in patients who underwent repeat hepatic resection did not differ from those who underwent primary resection. Multivariate analysis identified portal invasion at the first hepatic resection and a disease-free interval of ,1.5 years after primary hepatic resection as independent risk factors for survival after repeat hepatic resection. The 12 patients who did not show either of the two prognostic factors had 3- and 5-year survival rates of 91.7 and 68.8%, respectively, after repeat hepatic resection. Conclusions:, Our findings suggest repeat hepatic resection as the treatment of choice for recurrent HCC patients without portal invasion at the first resection whose recurrence develops after a disease-free interval of >1.5 years since the previous surgery.

Particle embolization of recurrent hepatocellular carcinoma after hepatectomy

CANCER, Issue 10 2006
Anne M. Covey M.D.
Abstract BACKGROUND Complete surgical resection is the mainstay of treatment for patients with hepatocellular carcinoma (HCC). Unfortunately, most patients ultimately develop disease recurrence and the median survival from the time of recurrence is <1 year. The purpose of the current study was to review the authors' experience using bland hepatic arterial embolization to treat recurrent HCC after definitive surgical resection. METHODS The authors reviewed their single-center hepatic embolization database from 1995 through 2004 to identify patients who underwent bland hepatic arterial embolization for disease recurrence. Data analyzed included patient demographics, Okuda stage and Child score, imaging findings, and embolization variables. Recurrence-free survival (from surgery to disease recurrence) and survival time (from recurrence to last follow-up) were calculated using the Kaplan-Meier method. RESULTS The authors identified 45 patients treated with bland embolization for recurrent HCC after resection. Six patients also underwent ablative therapy after embolization. Of the 45 patients, 42 (93.3%) patients had Okuda Stage 1 disease. The median time to recurrence was 13 months. The median survival after embolization was 46 months, and actuarial survival rates at 1 year, 2 years, and 5 years after recurrence were 86%, 74%, and 47%, respectively, with a median follow-up of 31 months. Patients who developed disease recurrence with a solitary lesion had a significantly improved survival (P = .03) At the time of last follow-up, 3 patients (6.6%) were alive with no evidence of viable disease. CONCLUSIONS Bland arterial embolization was found to be an effective method of salvage therapy for patients with good liver function with recurrent HCC after prior surgical resection. Patients whose disease recurred with a solitary lesion appear to have a significantly increased survival compared with patients who develop disease recurrence with multiple tumors. A small proportion of patients can be rendered without evidence of viable disease. Cancer 2006. © 2006 American Cancer Society. [source]
