Background Increased serum levels of soluble interleukin-2 (IL-2) receptor alpha (sIL-2Rα) are an indicator of poor prognosis in patients with B-cell non-Hodgkin lymphoma (NHL).
We report a novel phase 2 clinical trial in patients with poor prognosis refractory non-Hodgkin lymphoma (NHL) testing the efficacy of haploidentical donor natural killer (NK) cell therapy (NK dose 0.5-3.27 × 10<sup>7</sup> NK cells/kg) with rituximab and IL-2 (clinicaltrials.gov NCT01181258).
Interleukin (IL)-21, a member of the IL-2 family, has antitumor activity and is now being tested in non-Hodgkin's lymphoma in combination with anti-CD20 antibodies.
Moreover, both IL-4 and IL-2/IL-12 are used in experimental treatment models for non-Hodgkin's lymphoma (NHL) despite their differing ability to elicit Th2 or Th1 responses, respectively.
(3) Immune reconstitution with HAART and immunostimulatory cytokines such as interleukin-2 (IL-2) and IL-12, combined with drugs that downregulate the replication or gene expression of tumor-associated viruses such as Epstein-Barr virus (EBV) and human herpes virus-8 (HHV-8), possibly in combination, should remain a primary goal in the treatment of HIV-NHL.
We report the results of a selected series of 57 patients with non-Hodgkin lymphoma (NHL) or chronic lymphocytic leukemia (CLL), in which only the culture stimulated with PHA/IL2 demonstrated the presence of an abnormal clone.
A 56-year-old man with refractory B-cell lymphocytic non-Hodgkin's lymphoma was treated in a Phase II study with interleukin-2 (IL-2) (Roussel-Uclaf, Romainville, France).
