The same progress in the recent therapeutic strategy for older adults with hematological malignancies has also been seen in younger adults. The standard initial therapy for elderly acute promylocytic leukemia is the combination with all-trans retinoic acid and anthracyclines. For other acute myeloid leukemias (AML), many trials of combination chemotherapy have not improved the outcome of elderly patients. Gemtuzumab ozogamicin,which is an immunoconjugate binding to CD 33 on the surface of AML blasts, has produced good results for elderly patients in either monotherapy or in combination with conventional chemotherapeutic drugs. One of the BCR-ABL tyrosine kinase inhibitors, imatinib mesylate, is active for elderly Philadelphia-positive leukemia including acute lymphoblastic leukemia and chronic myeloid leukemia. In the treatment of elderly diffuse large B cell lymphoma, combination of rituximab and cyclophosphamide+doxorubicin+vincristine+prednisone (CHOP) has become the therapy of choice based upon a Groupe d'Etude des Lymphomes de l'Adulte (GELA) trial even though there are some other trials for elderly patients such as dose-dense CHOP therapy. For follicular lymphoma, combination therapies of rituximab and cytotoxic drugs such as R-CHOP and R-CVP are also considered as promising therapies. For the management of multiple myeloma, high-dose chemotherapy, mainly melphalan with autologous stem cell transplantation, has become the standard treatment even for elderly patients less than 65 years of age.
