Abstract

This study was purposed to evaluate the efficacy of autologous peripheral blood hematopoietic stem cell transplantation (auto-PBHSCT) for patients with malignant lymphoma. From January 1992 to June 2012, 32 malignant lymphoma (ML) patients were treated with auto-PBHSCT in our hospital. There were 56 cases of non-Hodgkins lymphoma (NHL) and 16 cases of Hodgkin's lymphoma(HD). The preconditioning regimens of total body irradiation (TBI) plus cyclophosphamide combined with etoposide/pharmorubicin were used in 50 patients, and the BEAM (BCNU+etoposide+Ara-C+melphalan) were used in the other 22 patients. The average number of CD34(+) cells was (6.6 ± 4.9) ×10(6)/kg. The results showed that transplanted cells were engrafted and hematopoiesis was reconstituted in all patients. The median time of neutrophilic granulocyte recovery up to ≥ 0.5×10(9)/L was 12 ± 4.4 days, and the platelet recovery up to ≥ 20×10(9)/L was 14 ± 4.9 days . The transplantation related mortality was 4.2%. The patients were followed up for 6-217 months. The median follow-up time was 63.5 months. 1-year OS rate was 92.3 ± 3.2%. 3-years OS rate was 81.4 ± 4.9%. 5-years OS rate was 77.6 ± 5.3%. 10-years OS rate was 68.9 ± 6.8%. It is concluded that auto-PBHSCT is ef...Continue Reading

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
