What researchers measure

Primary outcomes

  1. severe late toxicity

    2-year toxicity of grade ≥ 3 related to SBRT according to CTCAE V4.03 classification.

    Time frame: from 3 months to 2 years following the end of radiotherapy

Secondary outcomes

  1. Local control

    2-year local control rate - Any local recurrence (T) will be considered as an event.

    Time frame: 2 years following the end of radiotherapy

  2. Locoregional control

    2-year locoregional control rate - Any local (T) or lymph node (N) recurrence will be considered as an event

    Time frame: 2 years following the end of radiotherapy

  3. Acute toxicity

    ≤ 3-month toxicity of grade ≥ 3 related to SBRT according to CTCAE V4.03 classification.

    Time frame: from the first fraction to 3 months after the end of radiotherapy

  4. disease free survival (DFS)

    2-year DFS rate - DFS is time from randomization to the date of first occurrence of any locoregional recurrence, distant progression or death from any cause.

    Time frame: 2 years following the end of radiotherapy

  5. Overall survival (OS)

    2-year OS rate - OS is defined as time from randomization to death from any cause

    Time frame: 2 years following the end of radiotherapy

  6. Quality of life (global evaluation)

    evaluated by EORTC QLQC30

    Time frame: at baseline, 1 month, 1 year and 2 years post radiotherapy

  7. Quality of life (specific evaluation for Head and Neck Cancer)

    evaluated by EORTC QLQ HN35 module

    Time frame: at baseline, 1 month, 1 year and 2 years post radiotherapy

  8. Nutritional impact

    evaluated by weight loss

    Time frame: during 2 years following the end of radiotherapy

  9. Nutritional support

    evaluated by the use of feeding tubes

    Time frame: during 2 years following the end of radiotherapy

  10. Predictive factors of toxicity

    clinical and/or dosimetric factors associated to late severe toxicities (grade ≥ 3 related to SBRT according to CTCAE V4.03 classification).

    Time frame: 2 years following the end of radiotherapy
