Résumé

<p><b>INTRODUCTION</b>Most hepatocellular carcinomas (HCC) develop in a background of underlying liver disease including chronic hepatitis B. However, the effect of antiviral therapy on the long-term outcome of patients with hepatitis B virus (HBV)-related HCC treated with chemoembolization is unclear. This study aimed to evaluate the survival benefits of anti-HBV therapy after chemoembolization for patients with HBV-related HCC.</p><p><b>METHODS</b>A total of 224 HCC patients who successfully underwent chemoembolization were identified, and their survival and other relevant clinical data were reviewed. Kaplan-Meier and Cox regression analyses were performed to validate possible effects of antiviral treatment on overall survival (OS).</p><p><b>RESULTS</b>The median survival time (MST) was 15.9 (95% confidence interval [CI], 9.5-27.7) months in the antiviral group and 9.6 (95% CI, 7.8-13.7) months in the non-antiviral group (log-rank test, P = 0.044). Cox multivariate analysis revealed that antiviral treatment was a prognostic factor for OS (P = 0.008). Additionally, a further analysis was based on the stratification of the TNM tumor stages. In the subgroup of early stages, MST was significantly longer in the antiviral-treatment group than in the non-antiviral group (61.8 months [95% CI, 34.8 months to beyond the follow-up period] versus 26.2 [95% CI, 14.5-37.7] months, P = 0.012). Multivariate analysis identified antiviral treatment as a prognostic factor for OS in the early-stage subgroup (P = 0.006). However, in the subgroup of advanced stages, MST of the antiviral-treated group was comparable to that of the non-antiviral group (8.4 [95% CI, 5.2-13.5] months versus 7.4 [95% CI, 5.9-9.3] months, P = 0.219). Multivariate analysis did not indicate that antiviral treatment was a significant prognostic factor in this subgroup.</p><p><b>CONCLUSION</b>Antiviral treatment is associated with prolonged OS time after chemoembolization for HCC, especially in patients with early-stage tumors.</p>

Résumé

<p><b>BACKGROUND</b>Previous prognosis analyses of colorectal cancer (CRC) patients with stage II and III disease were done as separate categories. The purpose of this study was to analyze prognostic factors associated with survival in a group of patients who underwent radical resection of stages II and III CRC.</p><p><b>METHODS</b>A retrospective review was performed for 141 consecutive stages II and III patients who had undergone radical resection of colorectal adenocarcinoma between May 2003 and November 2003. Univariate and multivariate analyses were performed to assess the effect of record variables on disease free survival and overall survival.</p><p><b>RESULTS</b>The median follow-up time was 59 months, and the 3- and 5-year survival rates were 76% and 68%, respectively. Four factors were independently associated with a worse disease-free survival: diabetes (hazard ratio (HR) 2.338; 95% confidence interval (CI) 1.011 - 5.407), expression of cyclooxygenase-2 (Cox-2) (HR 0.335; 95%CI 0.126 - 0.888), expression of matrix metalloproteinases 2 (MMP-2) (HR 0.233; 95%CI 0.101 - 0.541), expression of vascular endothelial growth factor (VEGF) (HR 0.295; 95%CI 0.088 - 0.996). Four factors were independently associated with a worse overall survival: lymph nodes metastasis (HR 1.67; 95%CI 1.29 - 2.14), Cox-2 positive (HR 0.056; 95%CI 0.247 - 0.731), MMP-2 positive (HR 0.398; 95%CI 0.190 - 0.836), VEGF (HR 0.364; 95%CI 0.090 - 0.716).</p><p><b>CONCLUSIONS</b>Diabetes, expression of Cox-2, MMP-2 and VEGF were independently associated with a worse disease- free survival. Lymph nodes metastasis, expression of Cox-2, MMP-2 and high level of VEGF predicted a poor overall survival.</p>
