Pilot Study of 18F-FAZA in Assessing Early Functional Response in Patients With Inoperable Non Small Cell Lung Cancer Undergoing Radiotherapy or Chemo-radiotherapy

Brief Summary:
Non-small cell lung cancer (NSCLC) has a poor prognosis if not caught early enough. One of the factors that may impact the ability to control NSCLC is low oxygen levels (hypoxia) inside the tumour. This study will use 18F-FAZA PET scans to assess whether patients have hypoxic tumours and to monitor the changes to the hypoxic areas of a tumour during currently available standard treatment. It is hypothesized that 18F-FAZA PET may predict response to treatment, local control, and/or survival in NSCLC.

Condition or disease Intervention/treatment
Lung Neoplasm Cell Hypoxia Other: 18F-FAZA Other: 18F-Fluorodeoxyglucose (18F-FDG)

Detailed Description:
Locally advanced NSCLC has a poor prognosis with a 5 year overall survival rate of only 15%. Tumour hypoxia may impact the ability to control NSCLC. Using 18F-FAZA PET, this study will assess patients for hypoxic treatment. With this information, we can start individualizing patient treatment to target hypoxia. The relationship between areas of hypoxia (18F-FAZA) and high glucose utilization (18F-FDG) will also be assessed.

Group/Cohort Intervention/treatment
Patients with inoperable NSCLC undergoing RT or Chemo-RT
Other: 18F-FAZA
Radioactive dose of 110-600 MBq per injection. Up to a maximum of 6 injections per patient: pre-Tx, after 4 weeks (20 fractions) of RT, then 4 weeks, 90 days and 12 months post-RT and upon logo-regional progression or recurrence.
Other Name: NAP

Other: 18F-Fluorodeoxyglucose (18F-FDG)
Radioactive dose of 100-710 MBq per injection. Up to a maximum of 6 injections per patient: pre-Tx, after 4 weeks (20 fractions) RT, then 4 weeks, 90 days, and 12 months post-RT, and upon loco-regional progression or recurrence.
Other Name: FluGlucoScan Injection

Primary Outcome Measures :
  1. To determine the relationship between hypoxic changes and the early local tumour response after definitive radiotherapy or chemoradiotherapy in NSCLC [ Time Frame: 2.5 yrs ]

Secondary Outcome Measures :
  1. To establish if a correlation exists between 18F-FAZA PET and FluGlucoScan Injection PET in determining responses to definitive treatment in NSCLC [ Time Frame: 2.5 yrs ]
  2. To assess if patterns of local failure/overall survival correlate with 18F-FAZA PET and/or FluGlucoScan Injection PET [ Time Frame: 7 yrs ]

  2. Patients with American Joint Committee on Cancer (AJCC) Stage I, II, IIIA, or IIIB with detectable tumour that can be encompassed by radiation therapy fields, including both primary tumour and the involved regional lymph nodes.
  3. Patients must be deemed to be suitable to undergo definitive (i.e. potentially curable) chemoradiotherapy or radiotherapy by the treating Physician.
  4. The prescribed radiotherapy dose must be a minimum of 60 Gy in 30 fractions

  2. Patients with post-resection intrathoracic tumour recurrence
  3. Patients eligible for definitive surgery (patients who are eligible for surgery, but surgery did not proceed are eligible for this trial)
  4. No distant or metastasis, prior chemotherapy, or thoracic neck or radiotherapy
  5. Evidence of any small cell histology
