Abstract

The response to and survival following first salvage therapy regimens for 243 patients with acute myelogenous leukemia (AML) treated between 1974 and 1985 were evaluated. Eighty (33%) patients obtained a complete remission (CR), 24% died prior to achieving a response, and 43% were resistant on their first salvage regimen. The median survival was 18 weeks. Five percent overall and 16% of the CR patients are predicted to survive for more than 5 years. The factor most strongly associated with response and survival was the duration of the initial remission with 49 of 82 (60%) patients whose initial CR duration was at least 1 year in duration obtaining a second CR v 31 of 161 (19%) for patients with a shorter remission (P less than .01). Age, liver function, serum lactic dehydrogenase (LDH), karyotype, and the proportion of blasts plus promyelocytes present at the time of starting salvage therapy were strongly associated with probability of response and survival. Multivariate analysis was used to develop logistic regression and proportional hazard models to predict probability of response and survival, respectively. The major regimens used were conventional-dose cytarabine (ara-C) (combined with anthracyclines or amsacrine), high-dose ara-C, rubidazone, amsacrine (AMSA), other anthracyclines, and autologous or allogeneic transplant programs. After allowing for the prognostic factors in the models, specific treatment regimens were not strongly associated with prognosis.
