RESUMEN

HYPOTHESIS: The choice of operative technique for resection of giant cavernous hepatic hemangiomas has an effect on outcome. DESIGN: Case series. SETTING: Tertiary hepatobiliary surgery-liver transplantation service. PATIENTS AND INTERVENTIONS: Fifty-two adult patients who underwent resection of symptomatic hepatic hemangiomas (38 [73%] in the right lobe; average diameter, 10.9 cm) by means of lobectomy or enucleation, with or without Pringle inflow occlusion. MAIN OUTCOME MEASURES: Blood transfusion, morbidity, mortality, and length of hospitalization. RESULTS: Patient age and sex and the size of hemangiomas were similar for patients who underwent lobectomy and enucleation. Right-lobe lesions were more often treated by enucleation, and inflow occlusion was used more frequently; transfusion requirements and length of hospitalization were similar for both techniques. Complications were more frequent after lobectomy. There were no deaths. In the latter years of the series, enucleation was used in 22 (63%) and inflow occlusion in 24 (69%) of 35 patients. CONCLUSIONS: Outcome is related to the operative approach used for resection of giant cavernous liver hemangiomas. Although lobectomy and enucleation are curative, enucleation offers greater preservation of normal hepatic parenchyma and fewer complications and is the preferred technique for suitable lesions.

RESUMEN

BACKGROUND: The incidence and mortality of hepatocellular carcinoma (HCC) are increasing in the United States. Whether surgery is associated with improved survival at the population level is relatively unknown. To address this question, we used a population-based cancer registry to compare survival outcomes between patients receiving and not receiving surgery with similar tumor sizes and health status. METHODS: By using the Surveillance, Epidemiology, and End Results database, we identified HCC patients who had surgically resectable disease as defined by published expert guidelines. After excluding patients with contraindications to surgery, we performed both survival analysis and Cox regression to identify predictors of improved survival. RESULTS: Of the 4008 patients diagnosed with HCC between 1988 and 1998, 417 were candidates for surgical resection. The mean age was 63.6 years; mean tumor size was 3.3 cm. The 5-year overall survival with surgery was 33% with a mean of 47.1 months; without surgery, the 5-year overall survival was 7% with a mean of 17.9 months (P <.001). In the multivariate Cox regression, surgery was significantly associated with improved survival (P <.001). Specifically, patients who received surgery had a 55% decreased rate of death compared with patients who did not have surgery, even after controlling for tumor size, age, sex, and race. CONCLUSIONS: This study shows that surgical therapy is associated with improved survival in patients with unifocal, nonmetastatic HCC tumors <5 cm. If this is confirmed in future studies, efforts should be made to ensure that appropriate patients with resectable HCC receive high-quality care, as well as the opportunity for potentially curative surgery.

RESUMEN

OBJECTIVE: To evaluate the variables affecting orthotopic liver transplantation (OLT) outcome for hepatitis B virus (HBV) in a large patient cohort over a 17-year period. SUMMARY BACKGROUND DATA: Historically, OLT for chronic HBV infection has been associated with aggressive reinfection and poor survival results. More recently, OLT outcome has been improved with the routine use of antiviral therapy with either hepatitis B immune globulin (HBIg) or lamivudine; however, HBV recurrence remains common. The authors studied the factors affecting HBV recurrence and outcome of transplantation, including the effects of combination viral prophylaxis with HBIg and lamivudine. METHODS: A retrospective review of 166 OLT recipients for chronic HBV over a 17-year period at a single center was performed. Median follow-up was 29 months. HBV recurrence was defined by HBsAg seropositivity after OLT. HBIg monotherapy was used in 28 (17%) patients, lamivudine monotherapy in 20 (12%), and HBIg and lamivudine combination in 89 (54%); 29 (17%) did not receive any HBV prophylaxis. Hepatocellular carcinoma (HCC) was present in 43 patients (26%) and urgent United Network for Organ Sharing (UNOS) status was assigned to 27 patients (16%). Univariate and multivariate analyses were performed to identify factors that affected OLT outcome. RESULTS: Overall 1-, 3-, and 5-year patient survival rates were 85.8%, 73.6%, and 71.8%, respectively. As expected, HBV recurrence-free survival rates were significantly lower than overall survival rates (76.4%, 58.7%, and 48.3%). When compared with a nontreated cohort, OLT recipients receiving combination viral prophylaxis with HBIg and lamivudine showed markedly reduced HBV recurrence rates and significantly improved 1- and 3-year recurrence-free survival rates. By univariate estimates, patient survival was reduced in the presence of HCC, in the Asian population, and urgent candidates by UNOS classification. Graft loss rates were significantly increased in urgent OLT candidates, Asians, patients with pretransplant positive DNA, and in the presence of HCC. Factors that were significant by univariate analysis or thought to be clinically relevant were subjected to multivariate analysis. By multivariate estimates, urgent UNOS or presence of HCC adversely affected patient and graft survival rates, whereas combination prophylactic therapy strongly predicted improved patient and graft survival rates as well as recurrence-free survival rates. CONCLUSIONS: Orthotopic liver transplantation for HBV under combination viral prophylaxis results in survival rates equivalent to other indications. Pretransplant viral replication, UNOS status, and the presence of HCC are all sensitive markers for posttransplantation outcome. Viral prophylactic therapy has effectively reduced HBV recurrence and prolonged survival outcomes. The combination of HBIg and lamivudine is the prophylactic regimen of choice.
