The central role of sequential accumulation of genetic alterations during the development of cancer has been firmly established since the pioneering cytogenetic studies successfully defined recurrent chromosome changes in spedfic types of tumor. In the course of carcinogenesis, cells experience several genetic alterations that are associated with the transition from a preneoplastic lesion to an invasive tumor and finally to the metastatic state. Tumor progression is characterized by stepwise accumulation of genetic *** does the dominant metastatic clone. Modern molecular genetic analyses have clarified that genomic changes accumulate during the development and progression of cancers. In comparison with the corresponding primary tumor,additional events of chromosomal aberrations (including gains or allelic losses) are frequently found in metastases, and the incidence of combined chromosomal alterations in the primary tumor, plus the occurrence of additional aberrations inthe distant metastases, correlated significantly with decreased postmetastatic survival. The deletions at 3p, 4p, 6q, 8p, 10q,11p, 11q, 12p, 13q, 16q, 17p, 18q, 21q, and 22q, as well as the over-representations at 1q, 8q, 9q, 14q and 15q, have been found to associate preferentially with the metastatic phenotype of human cancers. Among of them, the deletions on chromosomes 8p, 17p, 11p and 13p seem to be more significant, and more detail fine regions of them, including 8p11, 8p21-12, 8p22, 8p23, 17p13.3, 11p15.5, and 13q12-13 have been suggested harboring metastasis-suppressor *** the past decade, several human chromosomes have been functionally tested through the use of microcell-mediated chromosome transfer (MMCT), and metastasis-suppressor activities have been reported on chromosomes 1, 6, 7, 8, 10,11, 12, 16, and 17.

The prognosis of patients with HCC still remains dismal. The life expectancy of HCC patients is hard to predict because of the high possibility of postoperative recurrence. Many factors, such as patient's general conditions, macroscopic tumor morphology, as well as tumor histopathology features, have been proven of prognostic significance. Female HCC patient often has a better prognosis than male patient, which might be due to the receptor of sex hormones. Younger patients often have tumors with higher invasiveness and metastatic potentials, and their survival and prognosis are worse than the older ones. Co-existing hepatitis status and hepatic functional reserve have been confirmed as risk factors for recurrence. Serum alpha-fetoprotein (AFP) is useful not only for diagnosis, but also as a prognostic indicator for HCC patients. AFP mRNA has been proposed as a predictive marker of HCC cells disseminated into the circulation and for metastatic recurrence. Many pathologic features, such as tumor size, number, capsule state, cell differentiation, venous invasion, intrahepatic spreading, and advanced pTNM stage, are the best-established risk factors for recurrence and important aspects affecting the prognosis of patients with HCC. Marked inflammatory cell infiltration in the tumor could predict a better prognosis. Clinical stage is still the most important factor influencing on the prognosis. Extratumor spreading and lymph nodal metastasis are independent predictors for poor outcome. Some new predictive systems have recently been proposed. Different strategies of treatment might have significant different effects on the patients' prognosis. To date, surgical resection is still the only potentially curative treatment for HCC, including localized postoperative recurrences. Extent of resection, blood transfusion, occlusion of porta hepatis, and blood loss affect the survival and prognosis of HCC patients. Regional therapies provide alternative ways to improve the prognosis

The prognosis of hepatocellular carcinoma (HCC) still remains dismal, although many advances in its clinical study have been made. It is important for tumor control to identify the factors that predispose patients to death. With new discoveries in cancer biology, the pathological and biological prognostic factors of HCC have been studied quite extensively. Analyzing molecular markers (biomarkers) with prognostic significance is a complementary method. A large number of molecular factors have been shown to associate with the invasiveness of HCC, and have potential prognostic significance. One important aspect is the analysis of molecular markers for the cellular malignancy phenotype. These include alterations in DNA ploidy, cellular proliferation markers (PCNA, Ki-67, Mcm2, MIB1, MIA, and CSE1L/CAS protein), nuclear morphology, the p53 gene and its related molecule MD M2, other cell cycle regulators (cyclin A, cyclin D, cyclin E, cdc2, p27, p73), oncogenes and their receptors (such as ras, c-myc, c-fms, HGF, c-met, and erb-B receptor family members), apoptosis related factors (Fas and FasL), as well as telomerase activity. Another important aspect is the analysis of molecular markers involved in the process of cancer invasion and metastasis. Adhesion molecules (E-cadherin, catenins, serum intercellular adhesion molecule-1, CD44 variants), proteinases involved in the degradation of extracellular matrix (MMP-2, MMP-9, uPA, uPAR, PAI), as well as other molecules have been regarded as biomarkers for the malignant phenotype of HCC, and are related to prognosis and therapeutic outcomes. Tumor angiogenesis is critical to both the growth and metastasis of cancers including HCC, and has drawn much attention in recent years. Many angiogenesis-related markers, such as vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), platelet-derived endothelial cell growth factor (PD-ECGF), thrombospondin (TSP), angiogenin, pleiotrophin, and endostatin (ES) leve

Liver resection is still a complicated operation with a high risk of postoperative morbidity. This study was undertaken to analyze the risk factors for postoperative complications after liver resection. METHODS:From 2001 to 2004, a total of 146 patients underwent liver resection for malignant or benign lesions. Postoperative complications after the resection were classified as surgical and medical, their incidences were analyzed *** risk factors for both surgical and medical complications were analyzed. To increase the safety of liver resection, surgical techniques were modified after April 2003, including control of inflow or outflow and intra- operative test with methylene blue. RESULTS:Before April 2003, a series of 58 patients received liver resection. Modified surgical techniques were used in liver resections for 88 patients after April 2003.A total of 36 patients (24.7%) had postoperative complications. Surgical and medical complications occurred in 24 and 13 patients respectively (One patient had both surgical and medical complications). Perioperative blood transfusion was related to a higher risk of surgical complications (P<0.05). Patients with diabetes mellitus were associated with a higher risk of medical complications (P<0.05). Surgical complications and postoperative hospitalization were decreased after the use of modified surgical techniques (P<0.05). CONCLUSION:Postoperative surgical complications can be decreased by modified surgical techniques, and careful selection of patients for liver resection may help to decrease postoperative medical complications also.

AIM： To quantify the circulating DNA in plasma from patients with hepatocellular carcinoma （HCC） and to evaluate its prognostic value. METHODS： Blood samples were collected from 79 patients with HCC before operation, 20 patients with liver cirrhosis, and 20 healthy volunteers. Circulating DNA was extracted from plasma and quantified. The association between circulating DNA level and prognosis of HCC patients was evaluated. RESULTS： Compared with the healthy volunteers （17.6 ± 9.5 ng/mL）, a significant higher circulating DNA level was found in the patients with HCC （47.1 ± 43.7 ng/ mL, P = 0.000） or with liver cirrhosis （30.0 ± 13.3 ng/ mL, P = 0.002）. The circulating DNA level was closely associated with tumor size （P = 0.008） and TNM stage （P = 0.040）, negatively associated with the 3-year diseasefree survival （DFS）（P = 0.017） and overall survival （OS）（P = 0.001）. CONCLUSION： Large or invasive tumor may release more circulating DNA, and higher level of circulating DNA may be associated with poor prognosis of HCC patients.

AIM: To identify the prognostic value of hepatitis B virus(HBV) and hepatitis C virus(HCV) infections in patients with intrahepatic ***: A search was performed for relevant publications in Pub Med, EMBASE and Web of Science databases. The pooled effects were calculated from the available information to identify the relationship between HBV or HCV infection and the prognosis and clinicopathological features. The χ2 and I2 tests were used to evaluate heterogeneity between studies. Pooled hazard ratios(HRs) with 95% confidence intervals(CIs) were calculated by a fixed-effects model, if no heterogeneity existed. If there was heterogeneity, a random-effects model was ***: In total, 14 studies involving 2842 cases were enrolled in this meta-analysis. The patients with HBV infection presented better overall and diseasefree survival, and the pooled HRs were significant at 0.76(95%CI: 0.70-0.83) and 0.78(95%CI: 0.66-0.94), respectively. Additionally, our study revealed that HCV infection was correlated with shortened overall survival in comparison with the control group(HR = 2.64, 95%CI: 1.77-3.93). We also found that HBV infection occurred more frequently in male patients [odds ratio(OR) = 1.91, 95%CI: 1.06-3.44] and was correlated with higher levels of serum aspartate transaminase(AST) and alpha-fetoprotein(AFP)(OR = 1.93, 95%CI: 1.11-3.35; OR = 3.86, 95%CI: 2.58-5.78) and a lower level of serum carbohydrate antigen 19-9(CA19-9)(OR = 0.47, 95%CI: 0.34-0.65). Moreover, HBV infection was associated with cirrhosis(OR = 6.44, 95%CI: 4.33-9.56), a higher proportion of capsule formation(OR = 6.04, 95%CI: 3.56-10.26), and a lower rate of lymph node metastasis(OR = 0.39, 95%CI: 0.25-0.58). No significant publication bias was seen in any of the enrolled ***: HBV infection may indicate a favorable prognosis in patients with intrahepatic cholangiocarcinoma, while HCV infection suggests a poor prognosis.
