[Subcutaneous bortezomib as a new promising way to successful maintenance therapy in multiple myeloma].

Multiple myeloma (MM) despite the introduction to clinical practice of a new drugs in the last years, and still searching of new points of the handle for targeting treatment, remaining incurable disease. Even most intensive and most modern induction-consolidation regimens is not in the state to eradicate of the clone of myeloma, and even complete remission in immunofixation the most often after some time ends progression. Optimal way of maintenance treatment is still searching, which would be maximally effective near acceptable toxicity. Now hypothesis about possible successful maintenance therapy, which may prolong survival of MM patients became more actual in the face of the introduction to the studies with maintenance of a new drugs as: thalidomide, lenalidomide and bortesomib. The expectations on the essential progress to establish the optimal bortesomib-based regimen of the maintenance treatment in MM cause the results of the studies with its subcutaneous administration, which proved comparable efficacy with advantage in toxicity profile, especially neurological in comparison to classic intravenous way.
