Outcome Measures
Primary Outcomes (3)
[18F]-AraG PET/CT uptake and infiltrating cytotoxic T-cell expression.
Examining the distribution of \[18F\]-AraG PET SUV metrics and counts of CD3+/CD8+/PD1- and CD3+/CD8+/PD1+ T-cells
Week 1 and Week 16
Pre-treatment [18F]-AraG PET/CT uptake and clinical response.
Correlation of pre-treatment \[18F\]-AraG PET/CT metrics (such as SUVmax, mean and uptake volume) and clinical response.
Pre-treatment
Changes between pre-treatment and mid-treatment [18F]-AraG PET/CT uptake and clinical response
Correlation between percentage changes in PET uptake values (max, mean, and peak) at pre- and mid-CRT and treatment response categories.
Pre-treatment and Week 16
Secondary Outcomes (3)
Individual cytotoxic T-cell activities (CD3+, CD8+, PD1-, and PD1+) and pre-treatment [18F]-AraG PET/CT uptake
Pre-Treatment
Tumor extent and standard uptake values between FDG PET and [18F]-AraG PET/CT imaging
treatment planning through post treatment ( up to 6 months)
[18F]-AraG PET/CT uptake over time and progressive-free survival
up to 6 months
Study Arms (1)
[18F]-AraG PET/CT scan
EXPERIMENTAL\[18F\]-AraG PET/CT scans to be performed according to the institution's standard of operation, which occurs on the first and sixteenth day of treatment.
Interventions
\[18F\]-AraG radiotracer, which occurs on the first and sixteenth day of treatment.
Concurrent chemoradiotherapy (CRT) with weekly doses of cisplatin.
Concurrent chemoradiotherapy (CRT) of 70Gy of radiation dose in 33 fractions.
Eligibility Criteria
You may qualify if:
- Patients ≥18 years of age.
- Ability to provide written informed consent and HIPAA authorization.
- LA-HNSCC in the larynx, hypopharynx, or human papillomavirus (HPV) negative oropharynx and is planning to receive definitive CRT as the SOC treatment, which includes a total of 70 Gy of radiation dose in 33 fractions, delivered over 5 days a week for 7 weeks, as well as planned weekly cycles of cisplatin (CDDP).
- Tumor stage III and IV (AJCC 8th edition).
- Unresectable cases.
- Eastern Cooperative Oncology Group (ECOG) performance status 0-2
- Willing and able to maintain the imaging protocol.
- Patients planning to receive pre-CRT and post-CRT FDG PET/CT scans as part of the standard clinical practice.
You may not qualify if:
- Diagnosis of immunodeficiency or receiving systemic steroid therapy or any form of immunosuppressive therapy within 7 days prior to the PET/CT scan.
- Pregnant or breastfeeding.
- Patients that will receive definitive induction chemotherapy or surgery.
- Patients who are unable to complete the radiation therapy.
