Head & neck reirradiation:
selection criteria
–
Treatment
related considerations
•
Previous treatment plan: previous dose in area of
recurrence ≤50Gy preferred (≥60-70Gy higher risk)
•
CTV = GTV + margin
•
Re-irradiation dose:
–
≥ 60Gy to achieve more local control
•
Critical structures:
–
Spinal cord: do not exceed 50Gy (total cumulative dose)
–
No cases of myelopathy if cumulative doses ≤60Gy in
2Gy equivalent doses
•
Brachytherapy for small recurrences in oral cavity and
oropharynx
•
IMRT or SBRT to reduce treatment-related toxicity
