title: Metronidazole as a radiosensitizer and high-dose radiation in advanced vulvovaginal malignancies, a pilot study.
abstract: Advanced vulvovaginal cancers have a survival of less than 25% in 5 years when treated with radiotherapy alone. The radiosensitizer metronidazole was used with unconventional radiation fractions in 10 patients. Local control was achieved in 9 out of 10 patients treated. Five of 10 patients have remained free of disease 9-30 months postdiagnosis. Two patients died with metastatic disease, but with local control. In only 1 patient did this approach fail to control local disease. The outcome of these 10 patients represents a significant improvement over conventional radiation. A randomized prospective study has been started on the basis of this pilot study.
