BACKGROUND: The EUROpean Ewing tumour Working Initiative of National Groups 1999 (EURO-E.W.I.N.G. 99) protocol prescribes six courses of vincristine, ifosfamide, doxorubicin, and etoposide (VIDE) as intensive induction chemotherapy for Ewing tumors (ET). Granulocyte-colony stimulating factor (G-CSF) is recommended. Adverse reactions (AR) were evaluated; quality assurance of data collection reviewed. PROCEDURE: Safety data from 4,746 courses of VIDE in 851 patients less than 50 years with ET were collected using a checklist and evaluated using descriptive statistics with sub-groups including gender, age, and tumor volume, analyzed by Wilcoxon and Kruskal-Wallis tests. RESULTS: Myelosuppression and infections were the major AR but with appropriate supportive therapy targeted dose intensity was maintained. Five VIDE-related deaths with three due to sepsis were reported. Renal and cardiac toxicity were reflected by glomerular filtration rate (GFR) <39 ml/min/1.73 m2 in 0.1%, tubular phosphate reabsorption < or = 0.80 in 1.9%, and left ventricular shortening fracture <28% in 2.5% VIDE courses. Statistically significant gender-associated AR concerning hemoglobin and platelets were observed with females > males as were age-associated AR concerning hemoglobin, WBC, platelets, stomatitis, and vomiting with AR decreasing with age, that is, children > adolescents > adults. No association of AR to tumor volume was found. In VIDE courses with and without G-CSF, neutropenia-related fever in 60.8% and 65.8%, and infection in 54.7% and 61.0% courses, respectively, were recorded. CONCLUSIONS: AR under VIDE remained within the expected range. Some AR, for example, hematotoxicity were significantly influenced by age and gender but not by tumor volume. G-CSF did not significantly influence neutropenia-related fever and infection. Solicited safety collection with checklists adequately reflects the burden per course. Copyright 2006 Wiley-Liss, Inc.
