Abstract

Relapsed acute lymphoblastic leukemia (ALL) in an adult is rarely cured. The majority of adult patients with relapsed ALL who are subsequently cured of their disease are given chemotherapy to achieve a second complete remission (CR) followed by a successful allogeneic bone marrow transplant. Overall, only a minority (typically 10% to 20%) of these relapsed patients in second CR are cured of their disease by an HLA-identical sibling allogeneic transplant. Many chemotherapy reinduction protocols have been tested in the setting of relapsed ALL. High-dose regimens appear to result in a greater incidence of second CRs compared with reinduction with standard vincristine, prednisone, anthracycline-based regimens. A combination of high-dose Ara-C (HDAC) and an anthracycline has the greatest likelihood of achieving a first CR in ALL patients with refractory disease or a second CR in relapsed patients. We have recently explored the activity of HDAC combined with a single a high dose of an anthracycline (idarubicin) or an anthracenedione (mitoxantrone) in adult patients with ALL. Our results indicate that these regimens are extremely active in the relapsed/refractory setting as well as in previously untreated adults. In order to compare t...Continue Reading

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.
