title: Treatment of relapse after allogeneic BMT with donor leukocyte infusions in 16 patients.
abstract: Sixteen patients with relapse after allogeneic BMT were treated with donor leukocyte infusions (DLI) from the original donor. The diagnoses at relapse were: CML in chronic phase (CP) (two patients), CML in accelerated phase (AP) (four patients), AML (four patients), MDS (one patient), ALL (four patients) and relapse of Hodgkin's disease (one patient). The patients received a mean of 5.2 x 10(8) leukocytes/kg with a range of 1.4-12.3 x 10(8) leukocytes/kg. Six patients obtained complete remission (CR), one with CML in CP, three with CML in AP, one MDS and one ALL. Partial remission (PR) was seen in three patients, one patient with CML in AP, one with AML and one with Hodgkin's disease. Seven patients had no response (NR) to the infusions, including one patient with CML in CP transplanted with a syngeneic donor. Four patients developed marrow hypoplasia after DLI (three CR and one PR) and two patients (ALL with CR and MDS with CR) were hypoplastic at relapse and marrow hypoplasia continued after DLI. GVHD occurred without GVL, but GVL only occurred in one patient with absence of GVHD. Eleven patients died of leukemia, six patients are alive. Three patients with CML are in CR 12, 12 and 32 months after DLI and one patient with ALL is in CR 15 months after DLI.
