Abstract

High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) has been applied to patients with diffuse large Bcell lymphoma (DLBCL); it is well established that ASCT shows significant survival benefits for chemosensitive relapse. However, half of relapsed patients are resistant to salvage chemotherapy, indicating that they are not suitable for ASCT. We retrospectively analyzed the clinical records of 47 patients with DLBCL classified as high or high-intermediate (higher) risk, according to the International Prognostic Index, who underwent upfront ASCT in first complete remission (CR1). Compared with 10 patients with similar characteristics who did not receive ASCT, event free survival at 5-year was significantly superior in ASCT group. Toxicity of ASCT was acceptable and therapy-related death was not observed. We therefore propose that upfront ASCT for higher risk DLBCL in CR1 might provide survival benefit, probably because the high-dose therapy removes minimally resided tumor.

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.

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.

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.
