Objective To investigate the effect of postoperative anti-viral therapy using adefovir dipivoxil in recurrence of hepatocellular carcinoma HCC with HBV infection. Methods Sixty HCC patients with HBV infection were randomized into two groups:Group A (n=23) received hepatectomy only, and Group B (n=37) received hepatectomy and postoperative therapy using adefovir dipivoxil. The changes in liver func-tion, the suppression of HBV-DNA, HBeAg seroconversion rate, tumor recurrence rate and median survival in the two groups were observed and compared. Results In Group B, serum albumin, total bilirubin, AST and ALT were significantly improved compared with Group A (P < 0.05). Furthermore, the rate of 6-month and 1-year HBV-DNA suppression, the rate of 6-month and 1-year HBeAg seroconversion were significantly improved compared with Group A (P < 0.05). In Group A and Group B the tumor recurrence rate was 82. 6% (19/23) vs 78.4% (29/37) (P > 0.05), the recurrence time was 7.3 vs9.6 months (P > 0.05) and the median survival time was 17.4 vs 24.9 months (P < 0.01). Conclusion The results suggest that an-ti-viral therapy using adefovir dipivoxil postoperatively may improve the remnant liver function, suppress the HBV reaction, prolong the survival for patients with HCC with HBV infection.

Objective To investigate the effect of standardization regional lymphadenectomy in radical resection of ductal adenocareinoma in the pancreatic head.Methods On the basis of routine panereaticoduodenectomy(whipple proceduce),we performed the standardization regional lymphadenectomy,the emphasis of the procedure was the resection of wide nodes,particularly the mesenteric root lymph nodes(14abcd),the paraaortic lymph nodes(16a2b1),the hepatoduodenal ligament lymph nodes(12abpeh),hepatic artery(Group 8)and coeliacus lymph nodes(Group 9). Results Eleven patients underwent this procedure,there was no operative mortality,1 case occurred pancreatic fistula,the lymph nodes metastasis occurred in 7(63.6%)patients,the posterior pancreaticoduodenal lymph nodes(Groupl3)and superior mensenteric artery(Groupl4)was the predominant metastatic site of the tumor,the rate of the second site metastasis to lymph nodes was 57.1%.of the 11 cases follow-up 1 died. Conclusion The radical pancreaticoduodenectomy combined with wide resection of standardization regional lymph nodes is a safe and effective procedure of the treatment of adenocarcinoma of the head of the pancreas.but the long-term survivalrate must be valued objectively with many cases.
