Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Histological verified loco-regional recurrence or new primary
  • Available dose plan from primary radiotherapy course
  • Comparative dose plan with advantages for proton radiotherapy e.g. integral dose
  • Dmax dose (0.03 cm3) on the cumulated photon dose plan≥90 Gy
  • Complete Response (CR)* after initial therapy, except in the case where the recurrence is considered a geometric miss (recurrence center of mass (COM) outside the 95% of prescription dose.
  • Inoperable or salvage surgery with R1/R2 resection, extranodal extension (ENE) or extensive soft tissue infiltration
  • Absence of distant metastasis at both

    • clinical examination AND
    • PET-CT or CT of thorax and upper abdomen
  • Life expectancy due to age and co-morbidity of >=1 year. The general condition must be sufficient to tolerate persistent significant side effects, e.g. tube or cannulae
  • PS<=2 (WHO See appendix)

Exclusion Criteria:

  • Radical surgery (R0) and absence of adverse prognostic pathological features
  • Lymphoma or malignant melanoma
  • Inability to attend full course of radiotherapy or follow-up visits in the outpatient clinic
  • As of 2019, patients with tracheal cannulas are excluded due to dose uncertainties. This may change if a technical solution becomes available.
