Autologous peripheral blood stem cell transplantation in the patients with hematologic malignancies and solid tumors

Objective To evaluate the long-term therapeutic effects of autologous peripheral blood st em cell transplantation (auto-PBSCT) on the treatment of hematological and soli d tumors. Methods Fifty-one patients were recruited in this auto-PBSCT study, in which several p otentially important parameters were studied including the optimal time for stem cell co llection, the dose of stem cell reinfusion, the time of hematopoietic reconsti tution, the disease free survival (DFS) and overall survival (OS), complication s related to transplantation, and maintenance chemotherapy after auto-PBSCT. Results After APBSCT, 3-year and 5-year survival rates of NHL were 83.3%; those of AM L were 74.7%; those of MM were 37.9% and 19%; those of ALL were 40% and 0% res pectively. Hematopoietic reconstitution was greatly promoted by granulocyte col ony stimulating factor (G-CSF). The mean time for patients’ neutrophil to reco ver up to >0.5×10(9) /L after APBSCT was 11.14 days in the group of the patien ts receiving G-CSF in contrast to 17.6 days in the group receiving no G-CSF. The most common complications of transplantation were fever, liver dysfunction and hypokalaemia, which were curable. No death was due to transplantation related complications.Conclusion Comparing with conventional chemotherapy, our study suggests that auto-PBSCT i s a very important therapeutic option that can significantly improve the prognos is in the patients with hematological and solid tumors, especially in the patien ts with AML and NHL.     

Expression of HLA-DR antigen in hepatocellular carcinoma and its up-regulation by interferon

Objective: To observe the expression of human leukocytic antigen DR (HLA-DR) in primary hepatocellular carcinoma (HCC) and its up-regulation by interferon (IFN). Methods: The expression of HLA-DR in 46 specimens of human HCC tissues, 4 human HCC cell lines (SMMC-7721, HCC-9204, BEL-7402 and HHCC) and a human hepatocyte cell line QZG was respectively detected by immunohistochemical ABC staining and flow cytometry. The expression of HLA-DR in the 5 cell lines was detected by ELISA before and after the cells were treated with IFN-γ or IFN-α. Results:Eighteen out of 46 HCC tissues (39.1%) expressed HLA-DR, whereas all the normal liver tissues immediately adjacent to HCC tissues were HLA-DR-negative. No obvious HLA-DR-positive staining was found in all the 5 cell lines. The expression of HLA-DR was up-regulated in all the 5 cell lines after IFN-γ or IFN-α treatment. The up-regulation of HI A-DR in QZG cells was less obvious than that in HCC cell lines. The effect of IFN-γ was more significant than that of IFN-α. Conclusion: HCC tissues can express HLA-DR to some extent, but HCC cell lines do not express detectable HLA-DR. IFN can up-regulate HLA-DR expression in HCC cells.
