Study Summary

The purpose of this study is to explore biomarker development in patients with newly diagnosed Head and neck squamous cell carcinoma (HNSCC) receiving curative therapy.

  • Planned for curative surgery or (chemo)radiotherapy
  • Willingness to undergo repeat MRI imaging
  • Able to receive and understand verbal and written information regarding study and ableto give written informed consent
  • Adequate renal function: Calculated creatinine clearance >/= 30ml/min
  • Be able to lie comfortably on back for 1 hour

Exclusion

Exclusion Criteria:

Study Description

After being informed about the study and potential risks, all patients giving written informed consent will be assigned to Cohort A or Cohort B.

Cohort A will recruit up to 40 patients planned to receive curative radiotherapy for HNSCC. Patients will undergo a baseline fMRI (Functional Magnetic Resonance Imaging) scan and within 72 hours a biopsy of the primary tumor will be performed in out-patient clinic. In week 2 of radiotherapy a further biopsy of the primary site will be performed with a paired fMRI performed within 72 hours prior to biopsy assess evolving changes in imaging and tumor microenvironment biomarkers during radiotherapy. A further optional biopsy and paired MRI scan in week 4 will be considered for patients who are tolerating therapy without toxicities. 16-24 hours prior to each biopsy the volunteer will take oral pimonidazole.

Cohort B will recruit up to 20 patients planned to receive curative surgery for HNSCC. Each patient will undergo a baseline fMRI scan performed within one week prior to surgery. At time of initial consent they will receive a prescription for oral pimonidazole hydrochloride which they will be asked to take the 16-24 hours before planned surgery. Following surgery whole tumor samples will be processed to permit spatial reconstruction of pimonidazole staining hypoxia to correlate with fMRI imaging.
