| pubmed-article:6932996 | pubmed:abstractText | Twenty-eight patients with acute non-lymphoblastic leukemia (ANLL) were started on induction chemotherapy consisting of Cytosine Arbinoside (Ara C) and 6 thioguanine (TG). Daunorubicin (DNR) was used selectively in 20 of 28 patients who failed to respond by day 14 to the Ara C and TG combination. Seven patients, or 25%, achieved complete remission (CR) without requiring DNR during remission induction. The overall response rate was 89% (64% CR and 25% PR). The median duration of survival for the CR group was 578 days. 189 days for the partial remission (PR) group (P = .02). Patients in the age groups of 18--40 years and with acute myelomonocytic leukemia subtype had the best response rate. There was no difference in the survival of the DNR treated group of complete responders as compared to DNR non-treated group. These results suggest that even though the majority of patients do require DNR for the remission induction, a significant number, perhaps as high as 25% of previously untreated patients, will achieve remission without the use of DNR. A significant minority of patients, therefore, be spared the toxicity of DNR early in the course of their disease. | lld:pubmed |
