Interest in high-dose cytarabine (HDAC) for both induction and postremission therapy for acute myeloid leukemia (AML) prompted the Southwest Oncology Group (SWOG) to initiate a randomized trial comparing HDAC with standard-dose cytarabine (SDAC) for remission induction of previously untreated AML and to compare high-dose treatment versus conventional doses for consolidation therapy. Patients less than 65 years of age with de novo or secondary AML were randomized for induction between SDAC 200 mg/ m2/d for 7 days by continuous infusion or HDAC at 2 g/ m2 intravenously every 12 hours for 12 doses; both groups received daunorubicin (DNR) at 45 mg/m2/d intravenously for 3 days. Complete responders to SDAC were randomized to receive either two additional courses of SDAC plus DNR or one course of HDAC plus DNR.

Results with acute promyelocytic leukemia (APL) prompted comparison with patients from 1986 through 1991 and analysis of factors contributing to APL results. Patient and disease characteristics and treatment outcome were compared for all evaluable patients, with more detailed analysis of factors affecting APL treatment outcome.

Among 522 evaluable patients, 295 (57%) achieved complete remission (CR), including 70% of patients age 49 or less. Twenty-four patients (15%) age 49 or less in CR were not HLA-typed, mostly because of financial constraints.

High-dose antiemetic regimens, while effective, add significantly to the cost of treatment. This study compares the efficacy and cost of high-dose metoclopramide with a combination of phenobarbital and droperidol.

Recent in vitro evidence has suggested synergy between cytotoxic agents and interferon alfa-2b. This phase I-II protocol was initiated to study interferon alfa-2b in combination with melphalan and prednisone.

Because of the in vitro synergism between the IFNs and cytotoxic agents, we conducted a trial of 30 previously untreated patients with multiple myeloma utilizing various doses of alpha-2-IFN in combination with standard oral doses of melphalan and prednisone. The combination was well-tolerated without unusual or unexpected toxic effects.

A significant improvement is shown with an educational effort coupled with experience in use of the classification, and the importance of cytochemistry in the use of the classification is illustrated. A simplification of the classification, merging M1, M2, and M4 as M7, is proposed.

The reproducibility of the FAB classification is analyzed. The classification is reproducible in the 70% range in panel reviewer hands and allows remarkable reproducibility in the morphologic and cytochemical distinction of acute lymphoid leukemia (ALL) from acute myeloid leukemia (AML).

No significant association was observed between antigens at either the A or the B locus. At the C locus, in contrast, HLA-Cw5 was more prevalent in the patient group, four of 22 having it, compared with the control group, in which two of 138 individuals possessed it.

The Southwest Oncology Group carried out a phase II study of the drug in 126 patients with previously treated acute leukemia; 116 patients were evaluable. Good-risk patients were given doses of 450 mg/m2, and poor-risk patients were given doses of 300 mg/m2 approximately every 3 weeks.

AP and LDH showed no consistent patterns. The activities of AS-A and AS-B correlated well with the patient's clinical status, increasing during progression of disease and decreasing toward normal activities during responses to therapy, as judged from bone marrow cellularity and differential.

Cytarabine was infused continuously for five days. Patients entering complete remission randomly received maintenance treatment with COAP or OAP.

The son heterozygous for beta-thalassemia had an elevated Hb A2, but the index case did not. The data from this pedigree indicate that the delta-allele trans to the beta-thalassemia gene was reponsible for the increased delta-chain production.
