Novel Hypoxia Imaging for Head and Neck Cancer: Imaging Phenotype for Personalized Treatment
Study Details
Study Description
Brief Summary
Tumor hypoxia is one of the physiological factors for treatment resistance and likely contributes to poor overall survival among patients with head and neck cancer (HNC). Identifying hypoxic features of HNC may allow the personalizing treatment plan. The investigators propose multiparametric Hypoxia MR (HMR) imaging using diffusion, perfusion, and oxygenation as non-invasive, in-vivo imaging components of a hypoxia phenotype. Assessing the hypoxia phenotypes' expression will be critically important for characterizing and predicting CRT response among patients with advanced HNC.
A prospective cohort study will be conducted used multiparametric MR (MPMR) imaging correlated with treatment response assessed by 3 months fluorodeoxyglucose-positron emission tomography (FDG-PET). The image analysis approach will be developed to incorporate FDG-PET and quantitative MRI characteristics of tumor (ADC, oxygen-enhanced T1 and T2* maps, and volume transfer constant (Ktrans) to facilitate 3D visualization of multiparametric information. This proposed study's overarching goal is to develop and validate multiparametric HMR imaging using 18F - (fluoromisonidazole) FMISO-PET and immunohistochemistry (IHC) as the standard of references.

Detailed Description
The objectives of this feasibility study are; 1) To obtain pilot data for a full-scale study and measure the distribution of parameters of the hypoxia MR (perfusion, diffusion, oxygenation, and acidosis) imaging, 2) To assess association of various hypoxia MR metrics with outcome, response to chemoradiotherapy (CRT) determined by 3 months post CRT FDG-PET/CT. 3) The metrics developed on hypoxia MRI wil be validated against F-18 FMISO-PET/CT and whole specimen IHC (immunohistochemistry). The data obtained from this pilot study will allow us to measure the effect size (difference in hypoxia MR metrics between responder and non-responder) for a larger, full-scale diagnostic study in the future, as well as to determine which hypoxia MR parameters have a strong association with desired outcome (response to CRT) in the future study.
The long-term objective of this research is to evaluate hypoxia MR phenotype that can be incorporated into treatment planning for IMRT (intensity-modulated radiotherapy), identify subregions of tumor hypoxia, and predict response to chemoradiotherapy (CRT) in newly diagnosed head and neck squamous cell carcinoma. The investigators will develop hypoxia MRI using a widely available MRI platform that allows broad patients access to novel hypoxia MRI. The investigators will evaluate the accuracy of the prediction of response to CRT using quantitative variables derived from hypoxia MR at the baseline as well as early interval changes between the baseline and 2 weeks of intra-treatment MR scans. Response to CRT will be determined by 3 months post-treatment FDG-PET/CT.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| patients treated with CRT Two hypoxia MR scans will be performed, one at pre-treatment and one at 2 weeks into CRT. Patients receive FMISO-PET/CT scans prior to the initiation of CRT. |
Diagnostic Test: [18F]MISO-PET/CT
18F]MISO-PET/CT will be acquired in each patient as the standard of references of tumor hypoxia.
|
| patients treated with primary surgical resection. Hypoxia MR scan and FMISO-PET/CT scan will be performed prior to the treatment (surgery). Surgical specimen of excised primary tumor will undergo IHC staining. |
Diagnostic Test: [18F]MISO-PET/CT
18F]MISO-PET/CT will be acquired in each patient as the standard of references of tumor hypoxia.

Outcome Measures
Primary Outcome Measures
- The correlation of hypoxia volume between hypoxia MR and F18-FMISO PET [1 year]
the correlation of the percentages of hypoxia volume on hypoxia MR and F18-FMISO PET as the standard references
Secondary Outcome Measures
- The correlation of hypoxia volume between hypoxia MR and IHC with hypoxia biomarkers [1 year]
Percent volume of the hypoxic subregion measured on both hypoxia MR and IHC
- Response to chemoradiotherapy [1 year]
Correlation with hypoxia phenotype identified on hypoxia MR with response to chemoradiotherapy determined by pre and 3 month post treatment FDG-PET/CT as the standard clinical practice. Those patients with equivocal FDG-PET/CT will be followed clinically and conventional CT or MR imaging up to 1 year.
