Treatment with bortezomib in a patient with heavily pretreated refractory T-cell lymphoblastic lymphoma.

T-cell lymphoblastic lymphomas are highly aggressive non-Hodgkin's lymphoma (NHL) and account for approximately 3% of all adult NHL histologies, with poor prognosis. We describe a 38-year-old patient with T-cell lymphoblastic lymphoma, who responds to bortezomib and doxorubincin combination, following a failure of conventional chemotherapy. Two months after treatment, the patient showed near complete remission of the lymphadenopathy. These data suggest a possible synergistic effect with bortezomib in combination with doxorubincin and dexamethasone. To our knowledge, this is the first case of T-cell lymphoblastic lymphoma treated with bortezomib.
