Autologous and allogeneic high-dose therapy for melanoma

Opportunities for the treatment of melanoma with high-dose chemotherapy have been inadequately explored because of the failure of early studies to demonstrate an advantage for high doses of those agents with disease activity that could also be safely dose-escalated without excessive extramedullary toxicities. However, emerging concepts of tumor and transplantation immunology have recently coincided, providing the rationale for new strategies that exploit principles of allogeneic transplant to overcome immunologic tolerance and escape mechanisms in the tumor-bearing individual. It is hoped that this setting will provide an improved milieu for donor-derived immunotherapeutic intervention that takes advantage of shared tumor antigens with therapeutic potential shown in a variety of tumor vaccination studies.
