Weekly administration of 2-chlorodeoxyadenosine in patients with hairy-cell leukemia is effective and reduces infectious complications.

Abstract

In conclusion, we confirm that weekly administration of 2-CdA at a dose of 0.15 mg/kg for 6 courses appears to be very effective in HCL inducing a high CR rate, similar to that observed with daily c.i. administration. CR durability and relapse/progression rates are also comparable to standard 2-CdA schedule. Moreover this new regimen seems to be safer in pancytopenic patients, markedly reducing life-threatening infectious complications.
