PURPOSE: We determined the frequency of and risk factors for congestive heart failure following treatment for Wilms' tumor that included doxorubicin. PATIENTS AND METHODS: Flow sheets and medical records were reviewed to identify cases of congestive heart failure in a cohort of patients treated on National Wilms' Tumor Studies (NWTS)-1, -2, -3, and -4. The frequency of congestive heart failure was estimated using the Kaplan-Meier method. A case-control study was conducted to determine the relationship among cumulative doxorubicin dose, site(s), total dose of abdominal and thoracic irradiation, sex, and the frequency of congestive heart failure. RESULTS: The cumulative frequency of congestive heart failure was 4.4% at 20 years after diagnosis among patients treated initially with doxorubicin and 17.4% at 20 years after diagnosis among those treated with doxorubicin for their first or subsequent relapse of Wilms' tumor. The relative risk (RR) of congestive heart failure was increased in females (RR = 4.5; P =.004) and by cumulative doxorubicin dose (RR = 3.3/100 mg/m(2); P <.001), lung irradiation (RR = 1.6/10 Gy; P =.037), and left abdominal irradiation (RR = 1.8/10 Gy; P =.013). CONCLUSION: We conclude that congestive heart failure is a risk of treatment with doxorubicin for Wilms' tumor. Additional follow-up of those children treated on NWTS-4 will be necessary to determine if the decrease in dose to 150 mg/m(2) significantly reduces this risk.
PURPOSE: The European Organization for Research and Treatment of Cancer 58881 study was designed to test in a prospective multicentric randomized trial the value of high-dose (HD) intravenous (IV) cytarabine (Ara-C) added to HD IV methotrexate (MTX) to reduce the incidence of CNS and systemic relapses in children with increased-risk acute lymphoblastic leukemia (ALL) or stage III and IV lymphoblastic lymphoma treated with a Berlin-Frankfurt-Munster (BFM)-based regimen. PATIENTS AND METHODS: After completion of induction-consolidation phase, children with increased-risk (risk factor > 0.8 or T-lineage) ALL or stage III and IV lymphoblastic lymphoma were randomized to receive four courses of HD MTX (5 g/m(2) over 24 hours every 2 weeks) and four intrathecal administrations of MTX (Arm A) or the same treatment schedule with additional HD IV Ara-C (1 g/m(2) in bolus injection 12 and 24 hours after the start of each MTX infusion) (Arm B). RESULTS: Between January 1990 and January 1996, 653 patients with ALL (593 patients) or lymphoblastic lymphoma (60 patients) were randomized: 323 were assigned to Arm A (without Ara-C) and 330 to Arm B (with Ara-C). A total of 190 events (177 relapses and 13 deaths without relapse) were reported, and the median follow up was 6.5 years (range, 2 to 10 years). The incidence rates of CNS relapse were similar in both arms whether isolated (5.6% and 3.3%, respectively) or combined (5.3% and 4.6%, respectively). The estimated 6-year disease-free survival (DFS) rate was similar (log-rank P =.67) in the two treatment groups: 70.4% (SE = 2.6%) in Arm A and 71.0% (SE = 2.5%) in Arm B. The 6-year DFS rate was similar for ALL and LL patients: 70.2% (SE = 1.9%) versus 76.3% (SE = 5.6%). CONCLUSION: Prevention of CNS relapse was satisfactorily achieved with HD IV MTX and intrathecal injections of MTX in children with increased-risk ALL or stage III and IV lymphoblastic lymphoma treated with our BFM-based treatment protocol in which cranial irradiation was omitted. Disappointingly, with the dose schedule used in this protocol, HD Ara-C added to HD MTX, although well tolerated, failed to further decrease the incidence of CNS relapse or to improve the overall DFS.
