PURPOSE: Past reports indicate that alpha hemolytic streptococcal (AHS) organisms are a common cause of infection among acute myeloid leukemia (AML) patients. This study was intended to ascertain the population incidence and rate (infections per 100 patient-days of treatment) of AHS and to identify associated risk factors. PATIENTS AND METHODS: Patients (n = 874 with 151,350 days of risk) enrolled on the Children’s Cancer Group (CCG) protocol for newly diagnosed AML, CCG-2891, which randomly assigned intensity of induction and intensification, were prospectively evaluated for infectious complications. RESULTS: AHS occurred in 21% of patients, was primarily blood borne (86%), made up 21% of bacteremic infections, and had a recurrent incidence of 31% during subsequent therapy. AHS was more often life-threatening (59%) than other infections (41%) (P = .001). AHS rates increased with age less than 10 years (odds ratio [OR], 2.0; P = .007), intensively timed induction (OR, 1.8 to 1.9; P = .02), and high-dose cytarabine intensification (OR, 3.7; P < .0001). Among all courses, the greatest incidence (19%) and rate (0.41) were associated with the use of high-dose cytarabine. Gastrointestinal toxicity correlated significantly with AHS bacteremia (P < .01). Infection with AHS resulted in increased hospital days (P = .0001). Only among bone marrow transplant patients were overall survival (OR, 2.8; P = .0001) and disease-free survival (OR, 2.1; P = .008) decreased after AHS bacteremia. CONCLUSION: This study, the first to prospectively examine AHS incidence among uniformly treated patients in multiple institutions, established that as the intensity of AML therapy has increased, so has the rate of AHS. Young children, those with previous AHS bacteremias, and those receiving high-dose cytarabine are at particularly high risk of AHS bacteremia.

PURPOSE The purpose of this review was to determine the impact of high-dose cytarabine and asparaginase intensification, administered shortly after remission induction, on the outcome of childhood acute myeloid leukemia (AML). MATERIALS AND METHODS Three consecutive Childrens Cancer Group (CCG) trials of acute myeloid leukemia, CCG 251 (1979 to 1983), CCG 213P (1983 to 1985), and CCG 213 (1985 to 1989) with a total of 1,294 patients, were reviewed and provide the basis of this report. RESULTS CCG 213P demonstrated the importance of dose interval, in that two courses of cytarabine and asparaginase administered at 7-day intervals gave superior 5-year survival rates (58% v 41% from the end of induction, P < .04) to the same therapy administered at 28-day intervals. CCG 213 showed that there was no advantage to the maintenance therapy used for patients who received two courses of cytarabine and asparaginase at 7-day intervals (5-year survival, 68% [no maintenance] v 44% [maintenance] from the end of consolidation, P < .01). Inclusion of the 7-day interval cytarabine/asparaginase intensification was accompanied by an overall improvement in 5-year survival rates from diagnosis when compared with historical controls (CCG 213, 36% v CCG 251, 29%, P < .02) although other differences between these studies could also be responsible for the improvement seen. CONCLUSION High-dose cytarabine and asparaginase intensification eliminated the benefit of prolonged maintenance therapy in childhood AML and was accompanied by an overall improvement in survival.

AbstractThis analysis from the phase II BRIGHT AML 1003 trial reports the long-term efficacy and safety of glasdegib + low-dose cytarabine (LDAC) in patients with acute myeloid leukemia ineligible for intensive chemotherapy. The multicenter, open-label study randomized (2:1) patients to receive glasdegib + LDAC (de novo, n = 38; secondary acute myeloid leukemia, n = 40) or LDAC alone (de novo, n = 18; secondary acute myeloid leukemia, n = 20). At the time of analysis, 90% of patients had died, with the longest follow-up since randomization 36 months. The combination of glasdegib and LDAC conferred superior overall survival (OS) versus LDAC alone; hazard ratio (HR) 0.495; (95% confidence interval [CI] 0.325–0.752); p = 0.0004; median OS was 8.3 versus 4.3 months. Improvement in OS was consistent across cytogenetic risk groups. In a post-hoc subgroup analysis, a survival trend with glasdegib + LDAC was observed in patients with de novo acute myeloid leukemia (HR 0.720; 95% CI 0.395–1.312; p = 0.14; median OS 6.6 vs 4.3 months) and secondary acute myeloid leukemia (HR 0.287; 95% CI 0.151–0.548; p < 0.0001; median OS 9.1 vs 4.1 months). The incidence of adverse events in the glasdegib + LDAC arm decreased after 90 days’ therapy: 83.7% versus 98.7% during the first 90 days. Glasdegib + LDAC versus LDAC alone continued to demonstrate superior OS in patients with acute myeloid leukemia; the clinical benefit with glasdegib + LDAC was particularly prominent in patients with secondary acute myeloid leukemia.
