Outcome Measures

Primary Outcomes (1)

  • Efficacy of simultaneous-integrated boost with IMRT guided by FDOPA PET on Recurrence free survival in patient with recurrent glioblastoma

    Recurrence free survival: interval between the date of inclusion in the trial until the date of recurrence of irradiated site (or one of the irradiated sites, in case of multiple irradiation)

    up to 24 months

Secondary Outcomes (17)

  • Percentage of recurrence of irradiated sites

    up to 24 months

  • Characterization of recurrence sites: classified either as distant, marginal or in-field

    up to 24 months

  • Percentage of Recurrence free survival at 6 months

    At 6 months

  • Percentage of Recurrence free survival at 12 months

    at 12 months

  • Overall survival

    From date of inclusion until the date of death from any cause, assessed up to 72 months

  • +12 more secondary outcomes

Study Arms (2)

Simultaneous-integrated boost with Intensity-modulated radiation therapy (IMRT)

EXPERIMENTAL

* Planning Target Volume (PTV) 37,5 Gray (Gy): 37,5 Gy in 6 fractions of 6,25 Gy at the rate of one fraction each 2 days * Prescription isodose line (PIL) at 80%, corresponding to 30 Gy as total dose, or 5 Gy per fraction * PTV SIB 45 Gy: 45,0 Gy in 6 fractions of 7,50 Gy at the rate of one fraction each 2 days * PIL at 80% corresponding to 36 Gy as total dose, or 6 Gy per fraction

Radiation: Simultaneous-integrated boost with IMRT

Standard IMRT

NO INTERVENTION

* PTV 37,5 Gy: 37,5 Gy in 6 fractions of 6,25 Gy at the rate of one fraction each 2 days * PIL at 80%, corresponding to 30 Gy as total dose, or 5 Gy per fraction * No SIB
