Interventions

  • Radiation therapy

    Vaginal brachytherapy

    Vaginal brachytherapy should be delivered using a vaginal cylinder, or alternatively ovoids

  • Radiation therapy

    Adjuvant radiotherapy (EBRT +/- brachytherapy)

    Treatment is to be delivered using 4-18 MV photons. MV, kV or CBCT imaging capabilities are required. Planning systems with capability for DICOM data transfer must be used.
