Interventions and Outcome Measures

Arms

active comparator: Arm 1: Integrated Boost Radiotherapy

External beam radiotherapy 70Gy in 35 fractions to head and neck tumour and 56 Gy in 35 fraction to elective nodal regions. This will be given as single integrated boost or two-phase treatment at clinician discretion.

active comparator: Arm 2: Two Phase Radiotherapy

Standard of care external beam radiotherapy 70 Gy in 35 fractions to head and neck with delayed 40 Gy in 20 fractions (HPV+ oropharynx) or 50 Gy/25 (all other disease) to elective nodal regions. This will be given as reversed two-phase treatment.

Interventions

Standard of care external beam radiotherapy (single integrated boost)

70Gy in 35 fractions, 56 Gy in 35 fractions. Oral Pimonidazole 200 mg and 300 mg tablets.

Standard of care external beam radiotherapy (two-phase treatment)

70Gy in 35 fractions, delayed 40 Gy in 20 fractions or 50 Gy in 25 fractions. Oral Pimonidazole 200 mg and 300 mg tablets.

Primary outcome measure

  • Confirm feasibility of recruitment of HN patients for on treatment repeat biopsy of the primary tumor +/- neck nodes [ Time Frame: 7 weeks ]
  • Change in fMRI during radiotherapy [ Time Frame: 7 weeks ]
  • Assess changes in tumor microenvironment during differing radiotherapy scheduling via repeat biopsy. [ Time Frame: 7 weeks ]
