The study group was compared with a case-matched control group of 68 patients who received curative hepatectomy for HCC during the study period in a 1:2 ratio.RESULTS: The tumor recurrence rate was markedly lower in the sorafenib group(15/34, 44.1%) than in the control group(51/68, 75%, P = 0.002). The median disease-free survival was 12 mo in the study group and 10 mo in the control group. Tumor number more than 3, macrovascular invasion, hilar lymph nodes metastasis, and treatment with sorafenib were significant factors of disease-free survival by univariate analysis. Tumor number more than 3 and treatment with sorafenib were significant risk factors of diseasefree survival by multivariate analysis in the Cox proportional hazards model. The disease-free survival and cumulative overall survival in the study group were significantly better than in the control group(P = 0.034 and 0.016, respectively). CONCLUSION: Our study verifies the potential benefit and safety of adjuvant sorafenib for both decreasing HCC recurrence and extending disease-free and overall survival rates for patients with BCLC-stage C HCC after curative resection.展开更多

RF ablation has the following advantages in the treatment of hepatic hemangiomas: minimal invasiveness, definite efficacy, high safety, fast recovery, relatively simple operation, and wide applicability. It is necessary to formulate a widely accepted consensus among the experts in China who have extensive expertise and experience in the treatment of hepatic hemangiomas using RF ablation, which is important to standardize the application of RF ablation for the management of hepatic hemangiomas, regarding the selection of patients with suitable indications to receive RF ablation treatment, the technical details of the techniques, therapeutic effect evaluations, management of complications, etc. A final consensus by a Chinese panel of experts who have the expertise of using RF ablation to treat hepatic hemangiomas was reached by means of literature review, comprehensive discussion, and draft approval.展开更多

Of these, 100 patients who received radiofrequency-assisted hepatectomy(RF+ group) were compared to 79 patients who had hepatectomy without ablation(RF- group). The primary endpoint was intraoperative blood loss. The secondary endpoints included liver function, postoperative complications, mortality, and duration of hospital stay.RESULTS: The characteristics of the two groups were closely matched. The Pringle maneuver was not used in the RF+ group. There was significantly less median intraoperative blood loss in the RF+ group(300 vs 400 m L, P = 0.01). On postoperative days(POD) 1 and 5, median alanine aminotransferase was significantly higher in the RF+ group than in the RF- group(POD 1: 348.5 vs 245.5, P = 0.01; POD 5: 112 vs 82.5, P = 0.00), but there was no significant difference between the two groups on POD 3(260 vs 220, P = 0.24). The median AST was significantly higher in the RF+ group on POD 1(446 vs 268, P = 0.00), but there was no significant difference between the two groups on POD 3 and 5(POD 3: 129.5 vs 125, P = 0.65; POD 5: 52.5vs 50, P = 0.10). Overall, the rate of postoperative complications was roughly the same in these two groups(28.0% vs 17.7%, P = 0.11) except that post hepatectomy liver failure was far more common in the RF+ group than in the RF- group(6% vs 0%, P = 0.04).CONCLUSION: Radiofrequency-assisted hepatectomy can reduce intraoperative blood loss during liver resection effectively. However, this method should be used with caution in patients with concomitant cirrhosis because it may cause severe liver damage and liver failure.展开更多

For patients with multiple recurrent HCC after partial hepatectomy which cannot be treated by re-hepatectomy or local ablative therapy, the prognosis is extremely poor. sorafenib is a molecular-targeted agent which has been demonstrated in two global phase III randomized controlled trials to show survival benefit for advanced HCC. Here, we present a 56-yearold patient with HCC who showed complete clinical response after sorafenib was used for tumor recurrence which developed 3 mo after partial hepatectomy. There was no evidence of progression of disease for 60 mo till now after continuous treatment with sorafenib.展开更多

This technique significantly reduced the blood loss and facilitated the procedure of partial hepatectomy. We applied this technique in 182 patients who needed partial hepatectomy. We concluded that this method is simple and easy to occlude the vascular inflow and outflow, and allows an accurate delineation of the anatomic zone and therefore, simplifies the procedure of partial hepatectomy.展开更多
