Abstract

Long-term disease-free survival following conventional cytotoxic therapy is extremely rare in patients with advanced-stage mantle cell lymphoma (MCL). High-dose conditioning therapy consisting of hyperfractionated total body irradiation (TBI, 14.4 Gy) and cyclophosphamide (200 mg/kg) was therefore offered to 13 patients (four females/nine males) with advanced-stage MCL. The patients were relatively young with a median age of 49 years (range 30-60). High-dose cytarabine and mitoxantrone with granulocyte colony-stimulating factor (G-CSF) support were given for second-line therapy and mobilization of peripheral blood stem cells (PBSC). During cytokine-stimulated marrow recovery, a median of two leukaphereses (range 1-4) were performed. Using direct immunofluorescence analysis including two-color staining, the proportion of CD19+ B cells and CD34+/CD19+ B lymphoid progenitor cells was found to be extremely low with quantities below detection limit in approximately 50% of the autografts. At the time of autografting, nine patients (pts) were in first partial (five pts) or complete (four pts) remission, while four patients had achieved a second complete remission. Following myeloablative therapy a median number of 7.5 x 10(6) CD34+ ce...Continue Reading

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.
