    Journal: Am J Clin Oncol; 1987 Oct; 10(5):437-43. PubMed ID: 2821790.
    Abstract:
    Sixty patients with high-grade gliomas (including 50 patients with glioblastoma multiforme) were entered on four sequential Phase I trials combining continuous intravenous infusions of halogenated pyrimidines and high-dose brain irradiation. Patients received two 14-day infusions of bromodeoxyuridine (BUdR) or iododeoxyuridine (IUdR) during the initial wide field and later reduced field radiation treatment (total radiation dose 65-70 Gy). All patients were followed a minimum of 6 months or until death. The actuarial median survival was 13 months for the entire group, with an 18-month survival of 24%. No significant survival differences were observed based on BUdR versus IUdR, 12-h versus 24-h infusion schedule, degree of surgical resection, or sex. Good performance status and age under 50 years were significant favorable prognostic factors. Of interest, the 48 patients who completed planned treatment had a 14-month median survival, with a 30% 18-month survival. These survival observations are at least comparable to other combined modality trials in patients with glioblastoma multiforme. Ongoing and planned clinical trials using the halogenated pyrimidine analogs as radiosensitizers in patients with glioblastoma multiforme are discussed.
