Autologous bone marrow transplantation with 4-hydroperoxycyclophosphamide purged marrows for acute nonlymphocytic leukemia in late remission or early relapse.

| Abstract |
Twenty-four patients with acute nonlymphocytic leukemia (ANLL) were treated with high-dose chemotherapy or chemoradiotherapy followed by infusion of autologous marrow purged with 100 micrograms/mL of 4-hydroperoxycyclophosphamide (4HC). The marrow harvests were performed when there were less than 5% blasts in the marrow. Seven patients were transplanted in second complete remission (CR), eight in third CR, one in fourth CR, and eight in early relapse. The median time to achieve 500 neutrophils/microL or 1,000 leukocytes/microL was 30 days. A platelet count of 20,000/microL and 50,000/microL was achieved at a median of 67 and 91 days, respectively. One patient failed to engraft by day 58. There were five other transplant-related deaths: sepsis (one), intracerebral hemorrhage (one), veno-occlusive disease (one), and interstitial pneumonia (two). Four of seven evaluable patients transplanted in early relapse obtained a CR lasting 112, 143, 189, and greater than 615 days. Eight of 11 evaluable patients transplanted in CR have relapsed at a median of 153 days (range, 104 to 311). The actuarial survival for all patients was 19%. There was a trend toward improved relapse-free survival for patients transplanted in remission as opposed to those transplanted in relapse (P = .11).
