Cyclosporine treatment of refractory T-cell lymphomas

Abstract

Most patients with refractory T-cell lymphomas did not respond to CSA, suggesting that these malignancies are not interleukin-2 dependent or, alternatively, that CSA did not reach its intracellular target. In the two responding patients, the pattern of repeated rapid regression of disease after CSA administration and subsequent rapid recurrence after a temporary halt in therapy suggested that CSA was cytostatic rather than cytocidal or that the clinical remissions were mediated by the antiinflammatory effects of the drug.
