Association of hepatitis B virus infection and cirrhosis with liver metastasis in colorectal cancer / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To explore the relationship of hepatitis B virus (HBV) infection and cirrhosis with liver metastasis in colorectal cancer.</p><p><b>METHODS</b>Clinical date of 1176 colorectal cancer patients undergone surgical treatment in the Peking University School of Oncology between January 1999 and August 2004 were analyzed retrospectively to investigate the impact of HBV infection and cirrhosis on the occurrence of liver metastasis and prognosis of patients.</p><p><b>RESULTS</b>The incidence of liver metastasis was 8.8% (10/114) in the HBV infection group and 23.9% (254/1062) in the non-infection group (P<0.01). The 5-year survival rates of these two groups were 54.2% and 60.7% ( P>0.05). The incidence of liver metastasis was 3.8% (1/26) in the cirrhotic group and 22.9% (263/1150) in the non-cirrhotic group (P<0.05). The 5-year survival rates of these two groups were 60.9% and 59.9% ( P>0.05).</p><p><b>CONCLUSION</b>Both hepatitis B virus infection and cirrhosis are associated with less liver metastasis in colorectal cancer, but have no impact on the survival.</p>

A scoring system to predict ascites after hepatectomy for hepatocellular carcinoma / 中华外科杂志

<p><b>OBJECTIVE</b>To establish a scoring system predicting the ascites postoperatively by analyzing the variant factors associated with massive ascites after hepatectomy in the patients with hepatocellular carcinoma (HCC).</p><p><b>METHODS</b>From January 2005 to January 2010, 324 patients with HCC underwent hepatectomy were analyzed retrospectively. There were 282 male and 42 female, aging from 17 to 84 years (mean age, 54 years). They were divided into two groups according to the volume of ascites. Variant preoperative, intraoperative and postoperative factors were compared and a scoring system was established to predict the postoperative ascites.</p><p><b>RESULTS</b>The univariate analyses revealed that various preoperative factors including prothrombin time, activated partial thromboplastin time, platelet count, albumin, aspartate aminotransferase had significantly difference in the two groups (P < 0.05). The operation time, intraoperative bleeding, hemihepatectomy or extended hemi-hepatectomy and the request of blood and serum transfusion had significantly difference in the two groups (P < 0.05). The multivariate analysis showed that the PLT, AST and the intraoperative plasma transfusion, hemihepatectomy or extended hemi-hepatectomy, the urine output and the drainage in the first postoperative day were independent factors (P < 0.05) for ascites. A scoring system was established based on the analysis. The specificity and the sensitivity were 86.2% and 83.3% respectively.</p><p><b>CONCLUSION</b>Variant factors are associated with postoperative ascites for hepatocellular carcinoma and the scoring system established can predict the ascites after hepatectomy accurately.</p>
