[Thalidomide in the treatment of multiple myeloma: focus on combination with bortezomib].

Thalidomide, the first clinically available immunomodulatory drug, reaches monotherapy treatment response in about 1/ 3 of significantly pretreated patients with multiple myeloma, and in combination with glucocorticoids approximately 50% response rate. After addition of conventional cytostatic into the triple combination, therapeutic response is achieved in 80% of untreated patients or about 60% of pretreated patients. Therapeutic response is achieved even in 1/3 of patients with refractory multiple myeloma resistant to other available treatment. With regard to the frequency of adverse effects, particularly peripheral polyneuropathy, its use as maintenance therapy was nearly abandoned. The combination of thalidomide and bortezomib has a high therapeutic potential that was accompanied by a high frequency of peripheral polyneuropathy in entry studies. After optimizing bortezomib schedule and route of administration, which lead to significant reduction in the frequency of polyneuropathy, this combination is currently a very interesting therapeutic alternative for clinical practice. This is one of the most economically available treatment regimens combining the benefits of two major drug classes in the treatment of multiple myeloma -  proteasome inhibitor and imunumodulatory drugs. There is also a renewed interest in thalidomide following sharp decline in its use in recent years in the Czech Republic. Comprehensive work is focused on summarizing the longterm experience with thalidomide, with special reference to combination with bortezomib.
