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.

BACKGROUNDS/AIMS: The prognosis of cirrhotic patients with hepatocellular carcinoma (HCC) depends on both residual liver function and tumor characteristics. The aims of this study was to construct a new prognostic index for HCC patients: the modified CLIP score, and to compare its discriminatory ability and predictive power with those of the CLIP score that is currently the most commonly used integrated staging score in patients of HCC. METHODS: A retrospective analysis of 237 cases of HCC diagnosed at Dong-A university hospital was performed. Prognostic analysis was performed for single variables by estimating survival distributions with the Kaplan-Meier's method, and statistically compared by the log-rank test. RESULTS: Patients had a mean age of 57.5 years and were predominantly males (79.7%). The overall median survival period was 25.7 months. It was correlated to ascites, portal vein thrombosis, AFP, tumor size, and Child-Pugh classification. The median survival period was 41.0, 25.2, 13.8, 13.4, and 6.5 months for CLIP scores 0, 1, 2, 3, and 4 to 6, respectively (P<0.001), and 42.1, 34.0, 25.7, 14.0, and 6.8 months for modified CLIP scores 0, 1, 2, 3, and 4 to 6, respectively (P<0.001). The Kaplan-Meier's curve showed that the modified CLIP score had additional explanatory power above that of the CLIP score. CONCLUSIONS: The modified CLIP score, compared with the CLIP score, particularly in the score 2- to 3- patient groups of HCC, had greater discriminant ability and survival predictive power, but was not able to discriminate 4- to 6- patient group.

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.

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.

OBJECTIVETo discuss the prognosis of primary liver carcinoma treated with local resection and factors affecting prognosis.

METHODSThe data of 130 patients who had been treated from October 1989 to October 1995 were analyzed retrospectively. We analyzed the concrete operating methods, the cause of postoperative complications and factors affecting prognosis.

RESULTSCurative local resection was performed in 130 patients. Operation-related mortality was 0.8% and the incidence of complication was 16.1% (n = 18). The overall 1-, 3- and 5-year survival rates were 82.1%, 60.6% and 48.2%, respectively. Involvement of blood vessels or liver capsules and the elevation of AST before operation were the significant factors affecting prognosis (P < 0.05).

CONCLUSIONLocal resection is a safe method characterized by little damage, rapid, less blood loss, low complication rate and good prognosis.

BACKGROUNDBlood transfusion has been found to be a devastating factor for outcomes of hepatectomy. This study was to assess the value of major hepatectomy without blood transfusion.

METHODSWe retrospectively studied 51 patients who had undergone major hepatectomy without blood transfusion, including 29 patients with primary liver cancer, from August 1997 to December 2000. Sixty patients undergoing major hepatectomy with blood transfusion including 48 patients with primary liver cancer served as controls. Hepatectomy was performed through normothermic interruption of the porta hepatis. Intraoperative ultrasonography was performed to define tumor margins, and an ultrasound dissector was used to dissect liver parenchyma.

RESULTSIn the study group, the operative mortality and morbidity and 1-, 2-, and 3-year recurrence rates were 0%, 9.8%, 24.1%, 27.6% and 31.0%, respectively. In the control group, they were 3.3%, 28.3%, 43.5%, 54.3% and 58.7%, respectively. Significant differences were seen in morbidity and recurrence rates of patients with liver cancer between the two groups (P < 0.05).

CONCLUSIONMajor hepatectomy without blood transfusion can reduce postoperative morbidity and recurrence rate of patients with liver cancer.

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.

OBJECTIVETo evaluate the prognostic value of surgical operation-related factors in patients with hepatocellular carcinoma (HCC).

METHODSThe clinical data of 234 patients after hepatic resection (214 men and 20 women) were retrospectively studied. Univariate and multivariate COX regression analyses were performed for surgical operation-related prognostic factors including age, gender, intraoperative blood loss, iatrogenic tumour rupture, transfusion, operation duration, hepatectomy extent, Pringle manoeuvre, with or without devarscularization, and complications (e.g. postoperative ascites, biliary leakage, incision infection, and pleural effusion). Kaplan-Meier and log-rank tests were used to compare survival rates. Kendall's tau bivariate analyses were used to examine the correlations of these surgical operation-related factors.

RESULTSUnivariate COX regression analysis revealed that iatrogenic blood loss (chi2 = 19.721, P < 0.001), transfusion (chi2 = 7.769, P = 0.005), tumour rupture (chi2 = 6.401, P = 0.011), operation duration (chi2 = 4.793, P = 0.029), and postoperative ascites (chi2 = 4.452, P = 0.035) were statistically significant predictors in patients with HCC after hepatic resection. Multivariate COX regression analysis revealed that pathological factors, such as blood loss (RR: 2.138, 95% CI: 1.556-2.939), tumour rupture (RR: 2.260, 95% CI: 1.182-4.321), and postoperative ascites (RR: 1.648, 95% CI: 1.088-2.469), independently influenced the HCC prognosis. Blood loss correlated with transfusion (Kendall's tau = 0.416, P < 0.001). There was no correlation between hepatectomy extent and blood loss (Kendall's tau = 0.057, P = 0.383), while transfusion closely correlated with the hepatectomy extent (Kendall's tau = 0.185, P = 0.004). The postoperative ascites closely correlated with Child classification (Kendall's tau = 0.151, P = 0.024).

CONCLUSIONSThe long-term survival of patients with HCC after hepatectomy may be improved by avoiding blood loss and iatrogenic tumour rupture. The indications of blood transfusion may not be strictly obeyed in some severe cases. Child class B and C cirrhotic patients may experience postoperative ascites and a worse prognosis, and therefore may be candidates for liver transplantation.

OBJECTIVETo investigate the effectiveness of anatomic method of separation in hepatectomy methods of decreasing postoperative complication and mortality for liver cancer patients.

METHODSThe clinical data of 398 patients with liver malignant tumors, admitted in our hospital during 2001 to 2007, were retrospectively analyzed. The anatomic method group (group A) included 243 contiguous patients of liver cancer who received hepatectomy by anatomical method of separation, while the traditional method group (group B) included 155 patients of liver cancer who received hepatectomy by traditional method of separation during the same period. Blood loss and transfusion during operation, postoperative liver function, complication and mortality of operation, and postoperative hospital stay were compared between these two groups.

RESULTSIn group A, the tumor diameters ranged (6.02 +/- 3.24) cm, the operative blood loss was (445 +/- 240) ml, and 52 patients (24.3%) underwent blood transfusion [range: (520 +/- 280) ml]. No mortality and intraabdominal hemorrhage, liver function failure, or other severe complications were noted. Only 12 patients (4.9%) suffered mild complications. The postoperative hospital stay was (13.4 +/- 4.9) days. In group B, the tumor diameters ranged (5.84 +/- 2.93 cm, the operative blood loss was (1200 +/- 320) ml, and 53 patients (34.2%) underwent transfusion [range: (1400 +/- 623) ml]. Five patients (3.23%) died within 30 days after operation. The total complication morbidity was 16.1% (25/155). Five patients suffered intraabdominal hemorrhage and 5 experienced liver function failure. Postoperative hospital stay was (18.9 +/- 10.3) days. The volume of blood loss and transfusion in group A were significantly less than in group B (P < 0.05). Mortality, severe complications, and total complication morbidity were significantly lower in group A than in group B (P < 0.05, P < 0.01). The postoperative stay was also significantly shorter in group A than in group B (P < 0.05).

CONCLUSIONAnatomical method of separation is an effective method of hepatectomy with relatively low complication and mortality.

The survival of a recent series of 823 cirrhosis patients who were followed up for a mean of 48 months was analyzed. Cirrhosis was ascribed to alcohol (26%), hepatitis virus B (58%), hepatitis virus C (11%) or both (2%), or was cryptogenic (3%). Features of decompensation were observed in 51% of the patients at entry, and newly developed in 44% of compensated patients within 5 yr. The 5-yr survival after decompensation was 25%. The leading causes of death were liver failure (53%), hepatocellular carcinoma (HCC, 23%), and variceal bleeding (10%). Early detection of HCC significantly improved the survival of cirrhosis patients. Biannual ultrasonography increased the detection rate of small HCC. Mortality of variceal hemorrhage was much lower in patients with Child-Pugh scores from 5 to 8 than in those with scores above 8 (5% vs. 52%). Endoscopic prophylaxis significantly decreased the incidence of first variceal hemorrhage, but the effect was insufficient to improve the rate of survival. Mortality of first spontaneous bacterial peritonitis was 18%. These data suggest that the mortality of major complications of liver cirrhosis has considerably decreased during the last two decades, while there was no remarkable improvement in long-term survival. More efficient management of etiologic factors would be required.
