Details and patient eligibility

About

Nowadays there is no randomized trials for comparison the effectiveness and tolerability of different conditioning regimens.

Bendamustine is a unique chemotherapeutic agent that combines alkylating action of nitrogen mustard and the activity of purine antimetabolite. Bendamustine has shown its effectiveness for the treatment of patients with chronic lymphoproliferative diseases such as chronic lymphocytic leukemia and several indolent lymphomas. The literature also presents evidence of the effectiveness bendamustine in patients with Hodgkin's lymphoma who received multiple lines of prior chemotherapy, including high dose chemotherapy and transplantation of peripheral hematopoietic stem cells. There are also data of using bendamustine as a part of conditioning regimen.

In this context, it was planned a study for evaluation the safety and effectiveness of the BeEAC (bendamustine, etoposide, cytarabine, cyclophosphamide) conditioning regimen prior to autologous transplantation of peripheral hematopoietic stem cells for the treatment of relapsed/refractory malignant lymphomas.
