Anti-HBV Surface Antigen Monoclonal antibody, Clone S3-322

Background and aim To evaluate the effect of intermittent pringle maneuver (IPM) on the long-term prognosis and recurrence of hepatocellular carcinoma (HCC). Methods Eligible studies were identified by PubMed and other databases from Jan 1st 1990 to Mar 31st 2019. Hazard ratios (HR) with 95% confidence interval (CI) were calculated to evaluate the effects of IPM on the long-term prognosis and recurrence of patients with HCC. Results Six studies were enrolled in this meta-analysis. Results showed that there were no differences between IPM group and non-IPM group in the pooled HRs for the overall survival (OS) and disease-free survival (DFS) (HR 1.04, 95%CI 0.84 similar to 1.28, P = 0.74; HR 0.93, 95% CI 0.81 similar to 1.07, P = 0.29; respectively). However, subgroup analysis showed that the pooled Odd ratios (OR) for the 1-year OS and DFS rates of the IPM group when compared with the non-IPM group were 0.65 (95% CI 0.45 similar to 0.94, P = 0.02), 0.38 (95% CI 0.20 similar to 0.72, P = 0.003), respectively. In addition, there were no significant differences in the proportions of liver cirrhosis, HBsAg (+), Child-Pugh A class, multiple tumor, vascular invasion, and major hepatectomy between groups of IPM and non-IPM. Conclusion Since IPM would increase the risk of early-recurrence, it should be used cautiously in the procedure of hepatectomy for resectable HCC. However, the current conclusion needs further validation.

Background: Breast cancer and hepatitis B virus (HBV) infection are serious public health issues in China. But the effect of HBV infection on breast cancer remains unclear. The objective was to assess whether HBV infection was associated with prognosis of breast cancer. Methods: A retrospective database of 1,924 invasive breast cancer patients from Sun Yat-sen University Cancer Center from 2008 to 2010 was established. Propensity score matching method was applied to balance baseline parameters. Logistic regression was used for identifying the independent risk factors of liver metastasis. Prognostic outcomes were evaluated via Kaplan-Meier analysis and Cox model. Results: Primary evaluation of gross data suggested HBV infection was associated with much higher rate of liver metastasis. 642 patients were matched for analysis. The median follow-up time was about 69 months. Patients with HBV surface antigen (HBsAg) (+) had a specially higher risk of liver metastasis aside of other distant organs than those with HBsAg (-). HBsAg (-/+) was identified to be an independent risk factor of liver metastasis [odds ratio (OR), 2.651; 95% confidence intervals (CI), 1.213- 5.796; P=0.015]. HBsAg (+) was associated with liver metastasis significantly in stage III or in estrogen receptor (ER) (+) and/or progesterone receptor (PR) (+), human epidermal growth factor receptor-2 (HER-2) (-) subtype. Meanwhile, patients with HBsAg (+) had significant shorter liver metastasis-free survival (LMFS) compared with HBsAg (-) patients (P=0.041). But the difference of overall survival (OS) between the HBsAg (-) and HBsAg (+) groups reached statistically no significance (P=0.425).The multivariate analysis suggested HBsAg (+) could worsen the outcome of LMFS [hazards ratio (HR), 2.450; 95% CI, 1.169-5.135; P=0.018]. Conclusions: In breast cancer, HBsAg (+) was associated with specially a higher rate of liver metastasis and thus worsened the LMFS. HBsAg (-/+) was an independent risk factor of liver metastasis.
