Outcome Measures

Primary Outcomes (2)

  • Change in tumor microenvironment during radiotherapy

    Repeat biopsy will be analyzed for haematoxylin and eosin (H\&E), pimonidazole (monoclonal IgG1 antibody, Hypoxyprobe MAb1), endogenous proteins associated with hypoxia and/or immune infiltrate, DNA, and RNA.

    Prior to radiotherapy, week 2 and week 4 of radiotherapy

  • Change in fMRI during radiotherapy

    Assessed through hypoxic regions visible on imaging scans

    Prior to radiotherapy, week 2 and week 4 of radiotherapy

Study Arms (2)

Cohort A

OTHER

Participants who are to receive standard of care radiotherapy will have one biopsy and MRI scan before starting radiotherapy and during week two of radiotherapy. Participants will also have an the option to consent to an additional biopsy and MRI scan during week 4 of radiotherapy. Oral pimonidazole will be taken the night before each biopsy.

Other: fMRIOther: Oral Pimonidazole

Cohort B

OTHER

Participants who are to receive standard of care curative surgery will have an MRI scan within one week prior to surgery. Tumor tissue from the surgery will also be collected for research. Oral pimonidazole will be taken the night before surgery.

Other: fMRIOther: Oral Pimonidazole
