Expanding role of bortezomib in multiple myeloma: nursing implications.

Multiple myeloma is the second most common hematologic malignancy and remains incurable, despite advances in chemotherapy and stem cell transplantation. Bortezomib, a novel proteasome inhibitor, is approved for the treatment of patients with multiple myeloma who have received at least 1 prior therapy. In the assessment of proteasome inhibition for extending remissions phase III trial of bortezomib versus high-dose dexamethasone, bortezomib led to significantly longer survival and time to progression and higher response rate in patients with relapsed multiple myeloma.

Advances in oral therapy in the treatment of multiple myeloma.

Conventional IV chemotherapy regimens used for induction chemotherapy or salvage therapy in the treatment of multiple myeloma (MM) are cumbersome, with a negative impact on patient quality of life. A number of new oral drugs, including immunomodulatory agents such as thalidomide and lenalidomide, have demonstrated potent antimyeloma activity in relapsed and refractory as well as newly diagnosed MM. Clinically, response rates of 56%-72% have been reported with the combination of thalidomide and dexamethasone in patients with newly diagnosed disease; however, the combination is associated with a higher incidence of side effects, including constipation, somnolence, peripheral neuropathy, and thromboembolic complications.

Bortezomib, a newly approved proteasome inhibitor for the treatment of multiple myeloma: nursing implications.

Multiple myeloma (MM), a malignancy of the plasma cells, accounts for an estimated 14% of all newly diagnosed hematologic malignancies. Advances in chemotherapy and stem cell transplantation have improved survival rates, but MM remains incurable. Bortezomib (Velcade, Millennium Pharmaceuticals, Inc.
