OBJECTIVETo investigate the effects of Chinese medicine (CM) herbal treatment based on syndrome differentiation on patients with unresectable hepatocellular carcinoma (HCC).

METHODSA total of 94 patients with unresectable HCC were reviewed between June 2008 and June 2011. Survival analysis was performed between patients who received CM with/without non-curative antitumor treatments of Western medicine (WM) (CM group, 30 cases) and patients who were not treated with CM but with non-curative antitumor treatments of WM or supportive treatment alone (non-CM group, 64 cases). Then, survival analysis was performed between patients treated with CM combined with non-curative antitumor treatments of WM (combination therapy group, 25 cases) and patients with non-curative antitumor treatments of WM alone (non-curative antitumor treatments group of WM, 52 cases). The survival analysis was performed by Kaplan-Meier method and prognostic factors for overall survival (OS) were assessed by the Cox proportional hazards regression model.

RESULTSThe median survival time (MST), 1- and 2-year survival rates of the CM group and the non-CM group were 36 months, 76.7%, 56.1% and 12 months, 48.4%, 26.6%, respectively. The Log-rank test revealed significant difference between the two groups in OS (P<0.01). Cox proportional multivariate analysis revealed that CM was an independent favorable prognostic factor for OS. The MST, 1- and 2-year survival rates of combination therapy group and non-curative antitumor treatments group of WM were 36 months, 76.0%, 55.5% and 13 months, 55.8%, 30.8%, respectively. There was significant difference in OS between the two groups (P=0.004).

CONCLUSIONSCM herbs based on syndrome differentiation have positive effects on survival of patients with unresectable HCC. Furthermore, combination therapy of CM and WM are recommended in HCC treatment.

OBJECTIVETo evaluate the influence of sirolimus on the long-term survival of patients after orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC).

METHODSClinic data of 165 consecutive patients who underwent OLT for HCC from February 2005 to March 2012 was analyzed retrospectively. Among them, 94 patients were treated with a sirolimus-based immunosuppressive protocol after OLT, while the other 71 patients with a FK506-based protocol. Postoperative survival time, survival, disease-free survival (DFS) and tumor recurrence rates between the two groups were compared.

RESULTSThe 2 groups were comparable in all clinicopathologic parameters. The sirolimus-based group had higher patient survival rates than the control group at 1-year (87% vs. 97%, P = 0.03), 2-year (80% vs. 88%), 3-year (76% vs. 85%) and 5-year (63% vs. 75%). The 1-year, 2-year, 3-year and 5-year recurrence rates were 12% vs. 3%, 17% vs. 9%, 21% vs. 9% (P = 0.04) and 31% vs. 16% (P = 0.03). Early and mid-HCC (I - II stage) of 131 cases (control group 61 cases, sirolimus-based group of 70 patients). The 1-year, 2-year, 3-year and 5-year survival rates were 90% vs. 97% , 80% vs. 90%, 78% vs. 86% and 65% vs. 82% (P = 0.04) and recurrence rates were 10% vs. 3%, 16% vs. 8%, 18% vs. 8% and 29% vs. 11% (P = 0.01).

CONCLUSIONThe sirolimus-based immunosuppressive protocol reduce long-term postoperative recurrence rate and improve the survival rate of patients after OLT for HCC significantly (especially early-mid HCC).

OBJECTIVE: To assess the clinical efficacy, safety, and risk factors influencing local tumor progression, following CT-guided radiofrequency ablation (RFA) of recurrent or residual hepatocellular carcinoma (HCC), around iodized oil retention. MATERIALS AND METHODS: Sixty-four patients (M : F = 51 : 13, 65.0 +/- 8.2 years old) with recurrent or residual HCC (75 index tumors, size = 14.0 +/- 4.6 mm) had been treated by CT-guided RFA, using retained iodized oil as markers for targeting. The technical success, technique effectiveness rate and complications of RFA were then assessed. On pre-ablative and immediate follow-up CT after RFA, we evaluated the size of enhancing index tumors and iodized oil retention, presence of abutting vessels, completeness of ablation of iodized oil retention, and the presence of ablative margins greater than 5 mm. Also, the time interval between transarterial chemoembolization and RFA was assessed. The cumulative local tumor progression rate was calculated using the Kaplan-Meier method, and the Cox proportional hazards model was adopted, to clarify the independent factors affecting local tumor progression. RESULTS: The technical success and technique effectiveness rate was 100% and 98.7%, respectively. Major complications were observed in 5.6%. The cumulative rates of local tumor progression at 1 and 2 years were 17.5% and 37.5%, respectively. In multivariate analyses, partial ablation of the targeted iodized oil retention was the sole independent predictor of a higher local tumor progression rate. CONCLUSION: CT-guided RFA of HCC around iodized oil retention was effective and safe. Local tumor progression can be minimized by complete ablation of not only index tumors, but targeted iodized oil deposits as well.

OBJECTIVETo investigate the therapeutic effects of Jiedu granules, a Chinese medicine (CM) compound, plus cinobufacini injection, which was extracted from skin of Bufo bufo gargarizans Cantor, to prevent the recurrence of hepatocellular carcinoma (HCC) after surgical resection.

METHODSIn this case-control trial, a total of 120 patients who stayed in Changhai Hospital were enrolled from December 2001 to December 2006. Sixty patients were treated with Jiedu granules plus cinobufacini injection to prevent tumor recurrence after operation (CM group) and 60 patients were treated with transcatheter arterial chemoembolization (TACE) after operation (TACE group). Progression-free survival (PFS) and overall survival (OS) rates were determined to evaluate the therapeutic effects of post-operative management of patients with HCC.

RESULTSPFS in the CM group was 18.07 months [95% confidence interval (CI): 12.49-23.65] and the 1-, 2-, 3-, 4- and 5-year PFS rates were 61%, 39%, 26%, 22% and 12%, respectively. PFS in the TACE group was 8.03 months (95% CI: 6.63-9.44) and the 1-, 2-, 3-, 4- and 5-year PFS rates were 34%, 11%, 7%, 2% and 0%, respectively. There was significant difference in survival rate between the two groups (P<0.01). The mean survival time (MST) of patients in the CM group was 49.53 months versus 39.90 months of the TACE group. The 1-, 2-, 3-, 4- and 5-year survival rates were 90%, 82%, 80%, 70% and 63%, respectively, in the CM group, and 79%, 70%, 60%, 60% and 36%, respectively, in the TACE group. There was significant difference in survival time between the two groups (P=0.045).

CONCLUSIONSJiedu granules plus cinobufacini injection, a combination that is commonly used for post-operation management of HCC, can postpone tumor recurrence and metastasis, prolong the survival time and increase the survival rate of post-surgical patients with HCC. However, these findings need to be confirmed in a prospective, randomized controlled trial.

BACKGROUND/AIMS: Hepatocellular carcinoma (HCC), which is the third most common cancer in Korea, has a very poor prognosis. However, only a few studies have performed a comprehensive survival-related analysis in all patients who were consecutively diagnosed and treated over a given period of time. The aim of this study was to determine the 5-year survival rate and its prognostic factors among HCC patients. METHODS: In total, 257 patients who were consecutively diagnosed with HCC between January 2000 and December 2003 were followed until death or until December 2008. We analyzed their survival outcomes according to their clinical characteristics, tumor staging, and treatment modalities, and determined the independent prognostic factors affecting survival. RESULTS: The patients were aged 59+/-10 years (mean+/-SD). During the follow-up period, 223 patients (86.8%) died and the overall median survival was 10.8 months; the 1-, 3-, and 5-year survival rates were 44.4%, 21.0%, and 12.1%, respectively. The outcomes in patients with tumor node metastasis (TNM) stage I or II and Child-Pugh class A or B were significantly better with surgical resection than with other treatment modalities (P<0.01). Patients who underwent supplementary transcatheter arterial chemoembolization as a second-line treatment after surgical resection had better outcomes than those who underwent surgical resection alone (P=0.02). Initial symptoms, Child-Pugh class, serum alpha-fetoprotein, tumor size, portal vein thrombosis, and TNM stage were found to be independent prognostic factors for survival among HCC patients. CONCLUSIONS: This retrospective cohort study elucidated survival outcomes and prognostic factors affecting survival in HCC patients at a single center.

BACKGROUND/AIMS: Transarterial chemoembolization (TACE) improves the survival of patients with unresectable hepatocellular carcinoma (HCC) and has been recommended as a first-line therapy for nonsurgical patients with large or multifocal HCC. The long-term outcome of HCC patients receiving TACE prior to hepatic resection is uncertain. METHODS: Between January 1997 and December 2007, 1,530 patients underwent hepatic resection for HCC at our center. Thirty-two patients received 1~12 sessions of TACE followed by surgical resection (TACE-surgery group). Their overall and recurrence-free survival rates were compared with those of 64 age- and sex-matched controls who underwent surgery only (surgery group). Overall and recurrence-free survival rates were analyzed. RESULTS: The 1-, 2-, and 5-year overall survival rates did not differ significantly between the TACE-surgery group and the surgery group (78%, 60%, and 26%, respectively, vs. 97%, 83%, and 45%, respectively; P=0.11); however, the 1-, 2-, and 5-year recurrence-free survival rates were significantly lower in the TACE-surgery group than in the surgery group (58%, 36%, and 7%, respectively, vs. 77%, 58%, and 32%, respectively; P=0.01). The distribution of recurrence sites in the TACE-surgery group were intrahepatic in 85.7% and extrahepatic in 14.3%, and did not differ from those in the surgery group (91.4% and 8.6%, respectively; P=0.66). CONCLUSIONS: HCC patients who underwent TACE before resection appear to have overall survival rates that are comparable to those without preoperative therapy, although recurrence rates appear to be higher in patients with TACE.

BACKGROUND/AIMS: Radiofrequency ablation (RFA) is an established curative therapeutic modality for unresectable hepatocellular carcinoma (HCC), and transarterial chemoembolization (TACE) has been used as a palliative treatment for inoperable HCC. It is still unknown whether RFA and TACE are equally effective for improving the survival of patients with unresectable HCC that is amenable to either treatment. The aim of this retrospective study was to compare the clinical impacts of two treatments, and analyze the prognostic factors for recurrence and survival. METHODS: Ninety-three patients with a single HCC smaller than 4 cm who showed complete responses (complete ablation or complete lipiodol tagging) after treatment with RFA (n=43) or TACE (n=50) between January 2002 and February 2009 were investigated. Univariate and multivariate analyses were performed for 13 potential prognostic factors using the Cox proportional-hazards model. RESULTS: The time-to-recurrence rates at 1, 2, and 3 years after treatment were 32.9%, 44.3%, and 55.4%, respectively, for the RFA group, and 42%, 68.3%, 71.7% for the TACE group. The probability of survival at 1, 2, and 3 years was 97.7%, 77.4%, and 63.1%, respectively, for the RFA group, and 95.9%, 76.1%, and 60.2% for the TACE group. The time-to-recurrence and overall survival rates did not differ significantly between the two treatment groups. A multivariate Cox proportional-hazards model revealed that a tumor size larger than 3 cm and lower serum albumin levels were independent risk factors for recurrence, and that being male, being seropositive for hepatitis B surface antigen, and having a higher serum albumin level were independent favorable prognostic factors for survival. CONCLUSIONS: TACE and RFA exhibited similar therapeutic effects in terms of recurrence and survival for patients with a single HCC smaller than 4 cm, if they could exhibited complete responses.

BACKGROUND AND AIMS: We investigated the five-year survival outcomes of a large cohort of hepatocellular carcinoma (HCC) patients who were treated at a single institute, and this is a follow-up study of a previous report. METHODS: Nine hundred four HCC patients who were treated at the National Cancer Center Korea were enrolled and they were followed till February 2007. RESULTS: The mean age of the patients was 56.0 years and 731 patients were male. Six hundred seventy-seven (74.9%) patients died and the overall 5-year survival rate (5-YSR) was 23.9%. The 5-YSRs of the patients with modified UICC stage I, II and III were 61.2%, 54.4% and 18.4%, respectively, and the median survival time was 4.3 and 3.7 months for the stage IVa and IVb patients, respectively. For the analysis of the treatment modality, surgical resection showed significantly better outcomes for the five-year survival as compared with transcatheter arterial chemoembolization (TACE) for Child-Pugh A patients with modified UICC stage I or II disease (80.1% vs 52.8%, respectively, P<.001), or stage III disease (60.7% vs 17.0%, respectively, P<.001). For patients with advanced stage IVb disease, TACE, systemic chemotherapy and radiotherapy increased the median survival period more than conservative management for the Child-Pugh class A patients. The serum alpha-fetoprotein level, portal vein tumor thrombosis, the Child-Pugh class, the tumor stage, the tumor type and symptoms were related to the prognosis. CONCLUSIONS: This study presented, for the first time, the 5-YSRs of a cohort of HCC patients.

OBJECTIVETo evaluate the efficacy of percutaneous laser ablation (LA) in the treatment for portal vein tumor thrombus (PVTT) of hepatocellular carcinoma (HCC).

METHODSThe PVTT of HCC patients were treated through percutaneous transhepatic laser ablation (PTLA). The survival rate, thrombus size, blood flow of embolized portal vein by thrombus, liver function, ascites and clinical presentation were observed.

RESULTSThe 6-month, 1-year and 2-year survival rate of these 93 patients were 82.8%, 53.0% and 34.1%, respectively. In 11 patients with partially occluded portal vein by PVTT, the cut-surface of the PVTT diminished significantly 6 months after LA. The color blood stream signal was seen again one day after LA in all of the other 82 patients with totally occluded portal vein by thrombus, and it could still be seen in 67 of those one month later, 57 (of 71) 3 months later, 40 (of 57) 6 months later, 27 (of 32) 1 year and 4 (of 6) 2 years later after LA. In the 38 patients who survived over 1 year, PVTT was gradually atrophied and disappeared eventually in 14, PVTT was atrophied and the portal vein changed into honeycomb-like appearance in 14. In the remaining 10 patients, PVTT continued to grow and made the portal vein enlarged. It was also observed that liver function, clinical symptom and ascites were improved in various degree after LA.

CONCLUSIONPercutaneous laser ablation might be an effective and safe treatment method for controlling portal vein tumor thrombus of hepatocellular carcinoma.
