RESUMO
Objective To investigate the expressions of platelet derived growth factor (PDGF) and survivin in hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) and to evaluate the relationships among the expressions of PDGF, survivin and the proliferation of cancer cells. Methods The expression of PDGF mRNA in 16 cases in HCC with PVTT group was observed by in situ hybridization and the results were compared with that in HCC tissue group. The expressions of PDGF and survivin protein in 36 cases in HCC with PVTT group were detected with immunohistochemistry and it was found that there was a correlation between them. Flow cytometry (FCM) was used to measure the proliferation of cancer cells and it was also used to analyze the relations among PDGF, survivin and the proliferation of cancer cells. Results The expression level of PDGF mRNA in HCC with PVTT group was significantly higher than that in HCC tissue group (P
RESUMO
ObjectiveTo evaluate the diagnostic and therapeutic methods for hilar cholangiocarcinoma(HCC). Methods In 20 HCC patients serum CA19 9, CA242, CEA were determined preoperatively. A total of 57 HCC patients underwent surgery. Postoperatively 89% (51/57) patients were followed up. Results The sensitivity and specificity of CA19 9 for preoperative diagnosis were 78% and 90%, respectively. 47%(27/57) patients underwent radical resection with 1, 3 year survival rates of 96% and 32%. ConclusionThe results showed that CA19 9 is helpful for the diagnosis of hilar cholangiocarcinoma. Radical resection is effective for prolonging the long term survival in patients with HCC.
