Methods： Between 01/01/2000 and 31/12/2012, 319 Uyghur HCC patients were treated at the Cancer Centre of The First Affiliated Hospital of Xinjiang Medical University. The data for the patients were obtained from a retrospective review of the patients＇ medical records. A total of 18 patients were excluded from the study because of incomplete information. The patients were classified into two groups： viral HCC and NBC-HCC. The clinical characteristics and prognostic factors were statistically analysed.Results： For all 301 patients, gender（P=0.000）, area of residence（P=0.002）, diabetes mellitus（P=0.009）, BMI（P=0.000）, cirrhosis（P=0.000）, tumour stage（P=0.004）, Child-Pugh class（P=0.000）, the TBIL level（P=0.000）, and the alpha-fetoprotein（AFP） level（P=0.000） were significantly different between the NBC-HCC and viral HCC groups. The NBC-HCC patients tended to be diagnosed at advanced stages; however, the NBC-HCC patients exhibited lower Child-Pugh scores than the viral HCC patients. In all patients examined, the 0.5-, 1-, 3- and 5-year overall survival（OS） rates were 35.6%, 20.3%, 12.6% and 4.5%, respectively. No significant difference in OS was observed between the two groups（P=0.124）. Cox multivariate analysis revealed that age（RR =1.539, P=0.001）, TNM stage（RR =12.708, P=0.000）, portal vein tumour thrombus（PVTT）（RR =2.003, P=0.000）, Child-Pugh class（RR =1.715, P=0.000）, and TACE ＋ radiotherapy/RFA（RR =0.567, P=0.000） were significant independent prognostic factors for HCC patients. Conclusions： The clinical characteristics differ between Uyghur patients with NBC-HCC and viral HCC. HCC in the Xinjiang region displays specific regional characteristics. Age, TNM stage, PVTT, Child-Pugh class and TACE ＋ radiotherapy/RFA are significant risk factors that influence patient survival.展开更多

OBI was determined by the HBV-DNA amplification of at least two different sets of primers by TaqM an realtime polymerase chain reaction. Possibly carcinogenetic factors such as alcohol abuse, diabetes mellitus, obesity and non-alcoholic steatohepatitis(NASH) were examined. Surgical outcomes were evaluated according to diseasefree survival(DFS), overall survival(OS) and diseasespecific survival(DSS).RESULTS OBI was found in 27/78 patients(34.6%) with NBNC HCC. The OBI patients were significantly younger than the non-OBI cases at the time of surgery(average age 63.0 vs 68.1, P = 0.0334) and the OBI cases overlapped with other etiologies significantly more frequently compared to the non-OBI cases(P = 0.0057). OBI had no impact on the DFS, OS or DSS. Only tumorrelated factors affected these surgical outcomes.CONCLUSION Our findings indicate that OBI had no impact on surgical outcomes. The surgical outcomes of NBNC HCC depend on early tumor detection; this reconfirms the importance of a periodic medical examination for individuals who have NBNC HCC risk factors.展开更多

We collected information about possibly carcinogenic factors such as alcohol abuse, diabetes mellitus, obesity and smoking habit from medical records. Smoking habits were subcategorized as never, ex- and current smoker at the time of surgery. The diagnosis of non-alcoholic steatohepatitis (NASH) was based on both clinical information and pathological confirmation.RESULTSAlcohol abuse, diabetes mellitus, obesity and NASH had no significant effect on the surgical outcomes. Current smoking status was strongly correlated with both overall survival (P = 0.0058) and disease-specific survival (P = 0.0105) by multivariate analyses. Subset analyses revealed that the current smokers were significantly younger at the time of surgery (P = 0.0002) and more likely to abuse alcohol (P = 0.0188) and to have multiple tumors (P = 0.023).CONCLUSIONCurrent smoking habit at the time of surgical treatment is a risk factor for poor long-term survival in NBNC-HCC patients. Current smokers tend to have multiple HCCs at a younger age than other patients.展开更多
