BACKGROUND/AIMS: Practice guidelines recommend endoscopic band ligation (EBL) and endoscopic variceal obturation (EVO) for bleeding from esophageal varices and fundal varices, respectively. However, the optimal treatment for bleeding from cardiac varices along the lesser curvature of the stomach (GOV1) remains undefined. This retrospective study compared the efficacy between EBL and EVO for bleeding from GOV1. METHODS: Patients treated by EBL or EVO via cyanoacrylate injection for bleeding from GOV1 were enrolled. Patients diagnosed with hepatocellular carcinoma or treated with endoscopic injection sclerotherapy were excluded. RESULTS: The study included 91 patients treated for bleeding from GOV1. The mean age was 56.3±10.9 years (mean±SD), and 78 of them (85.7%) were men. Overall, 51 and 40 patients were treated with EBL and EVO, respectively. A trend for a higher hemostasis rate was noted in the EVO group (100%) than in the EBL group (82.6%, P=0.078). Varices rebled in 15 patients during follow-up. The rebleeding rate was significantly higher in the EBL group than in the EVO group (P=0.004). During follow-up, 13 patients died (11 in the EBL group and 2 in the EVO group); the survival rate was marginally significant between two groups (P=0.050). The rebleeding-free survival rate was significantly higher in the EVO group than in the EBL group (P=0.001). CONCLUSIONS: Compared to EBL, EVO offered significantly lower rebleeding rates, significantly higher rebleeding-free survival rates, and a trend for higher hemostasis and survival rates. EVO appears to be the better therapeutic option for bleeding from GOV1.

BACKGROUND/AIMS: Radiofrequency ablation (RFA) is one of the most frequently applied curative treatments in patients with a single small hepatocellular carcinoma (HCC). However, the clinical significance of and risk factors for early massive recurrence after RFA—a dreadful event limiting further curative treatment—have not been fully evaluated. METHODS: In total, 438 patients with a single HCC of size ≤3 cm who underwent percutaneous RFA as an initial treatment between 2006 and 2009 were included. Baseline patient characteristics, overall survival, predictive factors, and recurrence after RFA were evaluated. In addition, the incidence, impact on survival, and predictive factors of early massive recurrence, and initial recurrence beyond the Milan criteria within 2 years were also investigated. RESULTS: During the median follow-up of 68.4 months, recurrent HCC was confirmed in 302 (68.9%) patients, with early massive recurrence in 27 patients (6.2%). The 1-, 3-, and 5-year overall survival rates were 95.4%, 84.7%, and 81.8%, respectively, in patients with no recurrence, 99.6%, 86.4%, and 70.1% in patients with recurrence within the Milan criteria or late recurrence, and 92.6%, 46.5%, and 0.05% in patients with early massive recurrence. Multivariable analysis identified older age, Child-Pugh score B or C, and early massive recurrence as predictive of poor overall survival. A tumor size of ≥2 cm and tumor location adjacent to the colon were independent risk factors predictive of early massive recurrence. CONCLUSIONS: Early massive recurrence is independently predictive of poor overall survival after RFA in patients with a single small HCC. Tumors sized ≥2 cm and located adjacent to the colon appear to be independent risk factors for early massive recurrence.

BACKGROUND/AIMS: Data on the epidemiology of alcoholic cirrhosis, especially in Asian countries, are limited. We compared the temporal evolution of patterns of alcoholic and nonalcoholic cirrhosis over the last decade. METHODS: We retrospectively examined the inpatient datasets of five referral centers during 2002 and 2011. The study included patients who were admitted due to specific complications of liver cirrhosis. We compared the causes of hospital admissions and in-hospital deaths between patients with alcoholic and nonalcoholic cirrhosis. RESULTS: Among the included 2,799 hospitalizations (2,165 patients), 1,496 (1,143 patients) were from 2002, and 1,303 (1,022 patients) were from 2011. Over time, there was a reduction in the rate of hepatic encephalopathy (HE) as a cause of hospitalization and an increase in the rate of hepatocellular carcinoma. Deaths that were attributable to HE or spontaneous bacterial peritonitis (SBP) significantly decreased, whereas those due to hepatorenal syndrome (HRS) significantly increased over time in patients with alcoholic cirrhosis. However, in patients with nonalcoholic cirrhosis, hepatic failure and HRS remained the principal causes of in-hospital death during both time periods. CONCLUSIONS: The major causes of in-hospital deaths have evolved from acute cirrhotic complications, including HE or SBP to HRS in alcoholic cirrhosis, whereas those have remained unchanged in nonalcoholic cirrhosis during the last decade.

BACKGROUND: Metastatic pathological fractures of the spine are a major problem for cancer patients; however, there is no consensus on treatment strategy. The purpose of this study was to evaluate various treatment options by analyzing their patterns for metastatic pathological fractures of the spine. METHODS: In this study, 54 patients (male:female = 36:18) who were diagnosed with metastatic pathological fractures of spine were recruited. Demographic data, origin of cancer, type of treatment, and results were obtained from electronic medical records. Treatment options were divided into radiotherapy (RT), vertebroplasty (VP) or kyphoplasty (KP), operation (OP), and other treatments. Treatment results were defined as aggravation, no response, fair response, good response, and unknown. The survival time after detection of pathologic fractures was analyzed with the Kaplan-Meier method. RESULTS: The mean age of the patients was 62.3 years. Hepatocellular carcinoma was the most common cancer of primary origin (n = 9), followed by multiple myeloma (n = 8). RT was the most common primary choice of treatment (n = 29, 53.7%), followed by OP (n = 13, 24.1%), and VP or KP (n = 10, 18.5%). Only 13 of 29 RT cases and 7 of 13 OP cases demonstrated a fair or good response. The mean survival time following detection of pathological spinal fractures was 11.1 months for 29 patients, who died during the study period. CONCLUSIONS: RT was the most common primary choice of treatment for metastatic pathological fractures of the spine. However, the response rate was suboptimal. Although OP should be considered for the relief of mechanical back pain or neurologic symptoms, care should be taken in determining the surgical indication. VP or KP could be considered for short-term control of localized pain, although the number of cases was too small to confirm the conclusion. It is difficult to determine the superiority of the treatment modalities, hence, a common guideline for the diagnosis and treatment of metastatic pathological fractures of the spine is required.

BACKGROUND/AIMS: We investigated the treatment outcomes and prognostic factors of hepatocellular carcinoma (HCC) with obstructive jaundice. METHODS: Among 2,861 patients newly diagnosed with HCC between 2002 and 2011, a total of 63 patients who initially presented with obstructive jaundice were analyzed. Only four patients presented with resectable tumors and underwent curative resection. In the other patients who presented with unresectable tumors, 5, 8, 9, and 18 patients received transarterial chemoembolization (TACE), chemotherapy, radiotherapy, and combined treatment, respectively. Both the clinical and the treatment factors that affect overall survival (OS) were analyzed. RESULTS: The median OS was 4 months, and the 1-year OS rate was 23%. Patients who received treatment for HCC had a significantly improved OS rate compared with the patients who received supportive care only (1-year OS, 32% vs 0%; p<0.01). Responders to treatment showed a better OS than nonresponders (1-year OS, 52% vs 0%; p<0.01). TACE and radiotherapy resulted in relatively good treatment responses of 64% and 67%, respectively. In multivariate analyses, treatment of HCC (p=0.02) and the normalization of serum bilirubin by biliary drainage (p=0.02) were significantly favorable prognostic factors that affected the OS. CONCLUSIONS: Unresectable HCC with obstructive jaundice has a poor prognosis. However, effective biliary drainage and treatment of HCC such as with TACE or radiotherapy improves survival.

BACKGROUND/AIMS: Spontaneous bacterial peritonitis (SBP) has been known to greatly influence the survival rate of patients with liver cirrhosis. However, the factors that affect the survival rate in patients with SBP need to be clarified. METHODS: This study enrolled 95 liver cirrhosis patients diagnosed with SBP. The laboratory findings of their serum and ascitic fluid were examined and the characteristics of the isolated microorganisms in their peritoneal fluid were analyzed. RESULTS: The proportion of patients with culture-positive SBP was 41.1%, and 47 microorganisms were isolated from the ascitic fluid. The proportions of cultured bacteria that were Gram negative and Gram positive were 57.4% and 40.4%, respectively. The proportions of Escherichia coli, Klebsiella species, and Streptococcus species were 25.5%, 19.1%, and 19.1%, respectively. Enterococcus species represented 12.8% of the microorganisms cultured. The overall survival rates at 6, 12, and 24 months were 44.5%, 37.4%, and 32.2%, respectively. There was no relationship between the bacterial factors and the survival rate in SBP. Multivariate analysis revealed that the presence of hepatocellular carcinoma (HCC; P=0.001), higher serum bilirubin levels (> or =3 mg/dL, P=0.002), a prolonged serum prothrombin time (i.e., international normalized ratio >2.3, P<0.001), renal dysfunction (creatinine >1.3 mg/dL, P<0.001), and lower glucose levels in the ascitic fluid (<50 mg/dL, P<0.001) were independent predictive factors of overall survival rate. CONCLUSIONS: HCC, higher serum bilirubin levels, a prolonged serum prothrombin time, renal dysfunction, and lower ascitic glucose levels are associated with higher mortality rates in cirrhotic patients with SBP.

BACKGROUNDBudd-Chiari syndrome (BCS) is characterized by liver sinusoidal congestion, ischemic liver cell damage, and liver portal hypertension caused by hepatic venous outflow constriction. The aim of this research was to investigate the clinicopathological features of BCS-associated hepatocellular carcinoma (HCC) and explore its surgical treatment and prognosis.

METHODSClinical data from 38 patients with BCS-associated HCC who were surgically treated in our hospital from July 1998 to August 2010 were retrospectively analyzed. The clinicopathological features and prognosis of patients with BCSassociated HCC and surgical treatment for BCS-associated HCC were investigated.

RESULTSCompared to the patients with hepatitis B virus (HBV)-associated HCC, the patients with BCS-associated HCC showed a female predominance, and had significantly higher cirrhosis rate, higher incidence of solitary tumors, lower incidence of infiltrative growth, higher proportion of marginal or exogenous growth, lower rate of portal vein invasion, and higher degree of differentiation. Median survival was longer in patients with BCS-associated HCC (76 months) than in those with HBV associated HCC (38 months). Of 38 patients with BCS-associated HCC, 22 patients who received combined surgery mainly by liver resection plus cavoatrial shunts exhibited hepatic venous outflow constriction relief, while the other 16 patients only underwent liver resection. The combined surgery group had significantly longer survival and lower incidences of post-operative lethal complications (P < 0.05). Multivariate analysis showed that relief of hepatic venous outflow obstruction was a protective factor for survival of patients with BCS-associated HCC, whereas portal vein invasion was a risk factor.

CONCLUSIONSBCS-associated HCC has a more favorable biological behavior and prognosis than HBV-associated HCC. For patients with BCS-associated HCC, tumor resection accompanied with relief of hepatic venous outflow obstruction can reduce the incidence of complications and extend survival.

OBJECTIVESTo compare the outcomes after liver resection for a single small hepatocellular carcinoma (HCC) (≤ 5 cm) between non-cirrhotic patients and cirrhotic patients, and to explore the influence of liver cirrhosis on recurrence and overall survival after liver resection in patients with a single small HCC.

METHODSA consecutive series of 256 patients with a single small HCC undergoing liver resection from April 2001 to October 2009 was retrospectively reviewed. Among the 256 patients, 227 patients were male, and 29 were female. The medium age was 49 years (ranged, 14 - 79 years); 224 (87.5%) patients were positive for hepatitis B surface antigen, 241 (94.1%) patients were with preoperative liver function of Child-Pugh grade A. The entire cohort were divided into non-cirrhosis group (n = 44) and cirrhosis group (n = 212). Univariate analysis and then multivariate analysis were performed to determine the prognostic factors of recurrence and overall survival after liver resection for all patients.

RESULTSThe 1-, 3-, 5-year recurrence-free survival rates after liver resection were 93.0%, 85.3%, and 68.5%, respectively, in non-cirrhosis group, while 81.1%, 58.6%, and 45.0%, respectively, in cirrhosis group. The 1-, 3-, 5-year overall survival rates after liver resection were 100%, 92.5%, and 92.5%, respectively, in non-cirrhosis group, while 93.8%, 78.7%, and 67.8%, respectively, in cirrhosis group. Both the recurrence-free survival and overall survival of non-cirrhosis group were significantly better than those of cirrhosis group (χ(2) = 8.756, P = 0.003; χ(2) = 8.603, P = 0.003). Cirrhosis, absence of tumor capsule, presence of microvascular invasion and moderate/poor tumor differentiation were the independent adverse prognostic factors for recurrence-free survival and overall survival in patients with a single small HCC after liver resection.

CONCLUSIONSCirrhosis is an important adverse prognostic factor for long-term survival in patients with a single small HCC after liver resection. Liver resection resulted in much worse survival for cirrhotic patients compared to non-cirrhotic patients.

The prevalence of hepatocellular carcinoma (HCC) has increased in recent years. However, HCC remains poorly characterized in elderly patients, and comprehensive data are limited. This study aimed to investigate the clinical characteristics, prognostic features and survival outcome of elderly HCC patients. We retrospectively analyzed 992 HCC patients treated at Dongsan Hospital from January 2003 to December 2007. The patients were divided into two age groups: < 70 yr (n = 813) and > or = 70 yr (n = 179). Elderly HCC patients, compared to younger patients, had significantly higher incidence of females (31.3% vs 18.9%, P = 0.001), hepatitis C-related disease (HCV antibody positivity 26.3% vs 9.2%, P = 0.001) and comorbid condition (53.6% vs 32.1%), but lower rates of hepatitis B-related disease (HBs antigen positivity 31.3% vs 69.4%, P = 0.001). There were no significant differences in underlying liver function, stage and survival outcomes. Factors significantly influencing the prognosis of HCC were Child-Pugh grade, number of HCC, level of alpha-fetoprotein, presence of metastasis. The survival outcome of older patients with HCC was not different from that of younger patients. There were no differences between groups in independent factors influencing the prognosis of HCC. Therefore, determining the optimal management strategy for elderly HCC patients is important to improve survival and long-term outcomes.

BACKGROUND/AIMS: Nonselective beta-blockers (NSBBs), such as propranolol, reportedly exert a pleiotropic effect in liver cirrhosis. A previous report suggested that survival was higher in patients receiving adjusted doses of NSBBs than in ligation patients. This study investigated whether low-dose NSBB medication has beneficial effects in patients with liver cirrhosis, especially in terms of overall survival. METHODS: We retrospectively studied 273 cirrhotic patients (199 males; age 53.6+/-10.2 years, mean+/-SD) who visited our institution between March 2003 and December 2007; follow-up data were collected until June 2011. Among them, 138 patients were given a low-dose NSBB (BB group: propranolol, 20-60 mg/day), and the remaining 135 patients were not given an NSBB (NBB group). Both groups were stratified randomly according to Child-Turcotte-Pugh (CTP) classification and age. RESULTS: The causes of liver cirrhosis were alcohol (n=109, 39.9%), hepatitis B virus (n=125, 45.8%), hepatitis C virus (n=20, 7.3%), and cryptogenic (n=19, 7.0%). The CTP classes were distributed as follows: A, n=116, 42.5%; B, n=126, 46.2%; and C, n=31, 11.4%. Neither the overall survival (P=0.133) nor the hepatocellular carcinoma (HCC)-free survival (P=0.910) differed significantly between the BB and NBB groups [probability of overall survival at 4 years: 75.1% (95% CI=67.7-82.5%) and 81.2% (95% CI=74.4-88.0%), respectively; P=0.236]. In addition, the delta CTP score did not differ significantly between the two groups. CONCLUSIONS: Use of low-dose NSBB medication in patients with liver cirrhosis is not indicated in terms of overall and HCC-free survival.
