BACKGROUNDPittsburgh modified TNM criteria is one of the prognostic models of orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC). In this study, we applied this prognostic system in a series of HCC patients receiving OLT to verify its reliability in the clinical prognostic prediction.

METHODSThe clinical record and follow-up data of 102 patients with HCC underwent OLT was collected. The patients were classified by 3 staging systems: the Pittsburgh Modified TNM Criteria, International Union Against Cancer (UICC) pTNM Staging System, and Milan Criteria. Survival rates of the patients were analyzed using the Kaplan-Meier method and the Log-Rank test, and then the prognostic values of the 3 staging systems were compared.

RESULTSAmong the 3 staging systems, the Pittsburgh Modified TNM Criteria showed the best stratification of patients with different prognosis. The overall survival rates of the patients at the Pittsburgh modified TNM stage I, II, III, and IV were 94.4%, 83.3%, 58.2%, and 36.8% at 1 year, and 79.4%, 62.5%, 26.2%, and 10.5% at 3 years, respectively. For those patients exceeding the Milan Criteria, the patients at Pittsburgh stages I and II had a significant higher survival rate than those at Pittsburgh stages III and IV (P < 0.001).

CONCLUSIONSThe Pittsburgh Modified TNM Criteria is a more reliable postoperative staging system than the UICC pTNM staging system for HCC patients receiving OLT. As providing more accurate prognostic classification, it could be reasonable to combine the Milan Criteria for recipient selection.

Along with the improvement of surgical techniques and post-transplant management, the role of liver transplantation in hepatocellular carcinoma (HCC) treatment has become increasingly important. Although HCC now is an indication of liver transplantation, the criteria of HCC candidates selection vary in different transplantation centers in China. On the contrary, the HCC candidates selection criteria in western countries are relatively strict, among which Milan criteria, University of California, San Francisco (UCSF) criteria, and Pittsburgh modified TNM criteria are widely acknowledged. However, Milan criteria and UCSF criteria only focus on tumor diameter and tumor number but ignore some important risk factors such as vascular invasion and histological differentiation. In our opinion, the biological behaviors of tumor are as important as tumor burden. A set of new candidates selection and prognostic criteria of liver transplantation in HCC patients named "Hangzhou criteria" has been established based on China's real situations and on the results of our long-term research. Hangzhou criteria expands and surpasses Milan criteria, including several important risk factors. According to Hangzhou criteria, more HCC patients are given opportunities to receive liver transplantation and achieved favorable long-term survival. Also in this article, we reviewed the peri-transplantation therapy of HCC to reduce the tumor recurrence and improve the long-term survival after transplantation for the purpose of making liver transplantation more effective and reliable for HCC treatment.

The five-year survival rate of patients after curative resection of hepatocellular carcinoma (HCC) has been reported to be 30 to 50 %, however the actual survival rate may be different. We analyzed the actual 5-year survival rate and prognostic factors after curative resection of HCC. Retrospective analysis was performed on 63 HCC patients who underwent curative resection from 1998 to 1999. A total of 63 cases were reviewed, consisting of 53 men and 10 women, with a median age of 49 years. These cases included all four pathologic T stages (pT stage) and had the following representation: stage 1 (1 case), stage 2 (17 cases), stage 3 (38 cases), and stage 4 (7 cases). In our study, the actual 5-year survival rate was 57.0% and the median survival time was 60 months. In addition, the patients in our study had an actual 5-year disease-free survival rate of 50.2% and a median disease-free survival time of 46 months. Thirty-one patients had recurrences, with a majority occurring within one year (65%). These patients with early recurrences had a poor actual 5-year survival rate of 5%. A univariate analysis showed that the prognostic factors influencing survival rate were the presence of satellite nodules, increased pT stage, HCC recurrence, and the time to recurrence (within one year). Interestingly, microvascular invasion made a difference in survival rate but was not statistically significant (p = 0.08). Furthermore, factors influencing the disease free survival rate include the presence of satellite nodules, microvascular invasion, and pT stage. Multivariate analysis identified pT stage as the only statistically related factor in determining the disease-free survival rate. The most important prognostic factor of HCC is recurrence. Moreover, the major risk factor for recurrence is an advanced pT stage. Therefore, performing prospective studies of postoperative adjuvant therapy is necessary to prevent recurrences after hepatic resection. Furthermore, active preventative treatment and early diagnosis of recurrences should be of the highest priority in the care of high-risk patient groups that have an advanced pT stage.

BACKGROUND/AIMS: Sclerosing hepatocellular carcinoma (HCC) is an unusual subtype of HCC that is characterized by an embedded dense fibrous stroma in the tubular neoplastic structures. We aimed to assess the surgical approaches and outcomes of sclerosing HCC. METHODS: We retrospectively analyzed the clinicopathologic features of 6 patients with sclerosing HCC who underwent surgical treatment at Asan Medical Center between July 1989 and December 2005. RESULTS: Six HCC patients with sclerosing HCC were diagnosed out of the total 1390 HCC patients (0.43%) during the study period. The mean age was 58 years and 4 patients were male. Weight loss and abdominal pain were the most common symptoms. The serum calcium and phosphorus levels were normal in all the patients. All of them were hepatitis B surface antigen-positive, but none was positive for hepatitis C. All the lesions were solitary. The tumor size ranged from 45 to 150 mm in diameter (median size: 81 mm). We performed right trisegmentectomy (n=1), central bisegmentectomy (n=1), right anterior segmentectomy (n=1), ex-vivo resection and autotransplantation (n=1) and right posterior segmentectomy (n=2). The median overall survival and disease free-survival periods were 24 months and 9.5 months, respectively. CONCLUSIONS: The incidence of sclerosing HCC was very low. Sclerosing HCC was often not correctly diagnosed before an operation, but performing resection prolonged the patients' survival and their prognosis was not worse than that for ordinary HCC. Our experience implicates that aggressive surgical treatment for sclerosing HCC is beneficial for patient survival.

OBJECTIVETo evaluate the effects of portal vein microscopic and macroscopic tumor thrombi on post-operation patients with hepatocellular carcinoma (HCC).

METHODSThree thousand three hundred and forty eight HCC patients were retrospectively reviewed, which were divided into no portal vein tumor thrombi (PVTT), microscopic PVTT and macroscopic PVTT groups according to the pathology, effects of portal vein microscopic and macroscopic tumor thrombi on post-operation patients's survival were studied by univariate analysis and overall survival was evaluated in each group.

RESULTSHazard ratio (HR) of portal vein microscopic tumor thrombi and macroscopic tumor thrombi was 1.421 and 3.136 respectively; The overall 1-, 3-, 5- and 10-year cumulative survival rate was 85.97%, 62.78%, 49.88% and 35.42% respectively, and mean time for survival was 59.7 months in group without PVTT, while 74.42%, 51.66%, 39.25% and 27.28% respectively and mean time for survival 39.1 months in group with microscopic PVTT, 52.59%, 25.97%, 20.42% and 11.33% respectively and mean time for survival 13.5 months in group with macroscopic PVTT.

CONCLUSIONSPVTT was an important prognostic factor for survival in post-operation patients with HCC while macroscopic PVTT was more danger than microscopic PVTT. The period of microscopic PVTT was the landmark affecting post-operation survival.

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 compare the prognostic efficacy of three clinical staging systems: the Chinese system (CS), CLIP scores, and TNM for hepatocellular carcinoma (HCC).

METHODS107 cases diagnosed as HCC between January 2000 and October 2003 were retrospectively analyzed. Their clinical stages were decided on the basis of data in CLIP or Chinese staging system when the HCC diagnosis had been confirmed. Fifty-three of the 107 patients underwent surgical resection. The TNM stage was therefore determined according to surgico-pathological results. The survival of those patients with respective to different stages were analyzed and compared using Kaplan-Meier curves and Log rank method.

RESULTSAll the patients were followed up after treatment. The 3-year survival rate in the CS Ia, Ib and CLIP 0 group were 100%. The 1- and 2-year survival rates of CS IIIa group was 68% and 51%, respectively. The 1-year survival in CS IIIb group was only 20.9%. The 1-, 2-, and 3-year survival rate in patients with a CLIP score beyond 4 was 57.1%, 49.9%, and 33.5%, respectively. In patients treated with surgical resection, the CS Ia group and TNM I group had a 3-year survival rate of 100%. The 1- and 3-year survival rate in CS IIb were 83.3% and 75.0%, in TNM III group 93.7% and 77.5%.

CONCLUSIONThe CLIP system may provide accurate prediction of prognosis based on early clinical features. The CS system is comparably efficient in predicting the prognosis of HCC patients, particularly in patients with severe cirrhosis.

OBJECTIVETo validate the predictive power of the 5th and 6th editions of TNM staging system (TNM-5, TNM-6) in a Chinese patient cohort with hepatocellular carcinoma (HCC) sized > or = 5 cm after radical hepatectomy.

METHODSConsecutive 121 patients with HCC sized > or = 5 cm undergoing radical hepatectomy between January 1995 and December 2002 were included. The impact of clinicopathological variables on prognosis was determined by univariate and multivariate analyses, after excluding 2 perioperative deaths.

RESULTSIn univariate analysis, TNM-5 stage did not show prognostic significance for overall or disease-free survival, as opposed to TNM-6 stage, Edmondson-Steiner grade, portal vein tumor thrombosis (PVTT), vascular invasion, satellite nodule, Child-Pugh grade, and hepatitis B surface antigen (HBsAg) positivity. When these significant variables were entered in multivariate analysis, Edmondson-Steiner grade was the sole independent prognosticator for both overall and disease-free survival, whereas Child-Pugh grade independently influenced disease-free survival. However, TNM-6 stage lost its predictive potential in multivariate analysis.

CONCLUSIONSNeither TNM-5 nor TNM-6 staging system is revealed to be independently prognostic in patients with HCC sized > or = 5 cm after radical hepatectomy. Therefore, TNM-6 calls for more support in many subsets of HCC patients.

OBJECTIVETo assess the survival of radiofrequency ablation (RFA) and investigate the prognostic factors affecting overall survival, local recurrence-free survival and disease-free survival in hepatocellular carcinoma (HCC).

METHODSA total of 192 HCC patients underwent RFA treatment in our department and were enrolled into this study. Among them, 151 patients were males and 41 were females (mean age, 59.2 years, range, 24 - 87 years old). The average tumor size was (3.9 +/- 1.3) cm (range, 1.2 - 8.0 cm). Of these 192 HCC patients, their Child-Pugh grade of A, B and C were 106, 77 and 9, respectively. According to UICC-TNM system, 57, 85, 44 and 6 patients were in stage I, II, III and IV respectively. Kaplan-Meier model and log-rank test were used in univariate analysis and COX regression model was used in multivariate analysis to identify prognostic factors for survival.

RESULTSThe 1-, 2-, 3- and 4-year overall survival were 84.9%, 69.1%, 60.4% and 52.8%, respectively. Local recurrence-free survival were 75.1%, 53.8%, 43.9% and 40.8%, respectively. Disease-free survival were 64.3%, 43.2%, 37.1% and 25.0%, respectively. The following factors were identified as independent prognostic factors for survival by multivariate model: (1) Overall survival: Child-Pugh classification, standard treatment protocol and UICC-TNM staging. (2) Local recurrence-free survival: Child-Pugh classification and UICC-TNM staging. (3) Disease-free survival: UICC-TNM staging, Child-Pugh classification and daughter lesion. Among these, both Child-Pugh classification and UICC-TNM staging were independent prognostic factors for three kinds of survivals.

CONCLUSIONSDegree of tumor progress (UICC-TNM stage, daughter lesion), treatment method (applying of standard treatment protocol) and patients' liver function are the most important factors for survival after RFA. So application of proper treatment strategy before, during and after RFA should be required to improve survival.

OBJECTIVETo investigate the risk factors affecting neoplasm recurrence and metastasis following liver transplantation (LT) and liver resection (LR) in patients with hepatocellular carcinoma (HCC) meeting Milan criteria.

METHODSWe retrospectively analyzed the clinical data of 88 patients with HCC meeting Milan criteria undergoing LT or LR in Nanfang Hospital between January, 2006 and December, 2011 and compared the survival rate and recurrence-free survival rate between the two groups. Univariate analysis of 12 variables during peri-operative period was carried out to screen the risk factors affecting neoplasm recurrence and metastasis.

RESULTSThe LT group and HR group had similar 1-, 3-, and 5-year-survival rates (P>0.05), but the LT group showed significantly higher 1-, 3-, and 5-year recurrence-free survival rates (P<0.05). The recurrence rate was much lower in LT group than in LR group (P<0.05). Multivariate analysis identified gender, tumor size, degree of pathological differentiation, and microvascular tumor embolism as independent risk factors affecting the recurrence-free survival rate.

CONCLUSIONPatients with HCC meeting Milan criteria undergoing LT have longer long-term recurrence-free survival. A male patient with a greater tumor size, microvascular tumor embolism, and poorly differentiated carcinoma is more likely to develop neoplasm recurrence and metastasis following the surgery.
