Primary Outcome Measures:
  • safety and feasibility of hypofractionated irradiation in patients with sacrococygeal chordoma using ions (protons or carbon ions) in raster scan technique [ Time Frame: From date of treatment start until 12 months after treatment. ]
    The evaluation is based on incidence of Grade 3-5 toxicity (NCI-CTC-AE) and/or discontinuation of the treatment for any reason. Endpoint is the proportion of treatments without Grade 3-5 toxicity (NCI-CTC-AE) up to 12 months after treatment and/or discontinuation of the treatment for any reason

Secondary Outcome Measures:
  • local progression free survival (LPFS) [ Time Frame: From date of treatment start until the date of first documented progression in MRI/CT scan assessed up to 12 months. ]
    local progression free survival (LPFS) is determined from start of treatment until local progression in imaging (>10% size increase)

  • Overall survival (OS) [ Time Frame: From date of treatment start until the date of death from any cause assessed up to 12 months. ]
    Further objectives are overall survival (OS) from date of treatment start until the date of death from any cause assessed up to 12 months

  • Quality of life (QoL) [ Time Frame: From date of treatment start up to 12 months. Evaluation at treatment start, at the end of treatment and 12 months after treatment. ]
    Quality of life (QoL) evaluated with EORTC-QLQ30 questionnaire.
