简要总结
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.
详细描述
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.

入选标准
- •Patients with histologically-proven, by biopsy or cytology, unresected lung cancer of the following histological types: squamous cell carcinoma; adenocarcinoma; undifferentiated large cell carcinoma, and non-small cell, not otherwise specified (NOS, diagnosis on cytology alone)
- •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.
- •Patients must be deemed to be suitable to undergo definitive (i.e. potentially curable) chemoradiotherapy or radiotherapy by the treating Physician.
- •The prescribed radiotherapy dose must be a minimum of 60 Gy in 30 fractions
- •Male or female ≥ 18 years of age. If female of child bearing potential and outside the window of 10 days since the first day of the last menstrual period, a negative pregnancy test is required.
- •ECOG/Zubrod status 0-1

- •Provide written informed consent prior to participation in the study
排除标准
- •Patients who have undergone complete or subtotal tumour resection

- •Patients eligible for definitive surgery (patients who are eligible for surgery, but surgery did not proceed are eligible for this trial)
- •No distant or metastasis, prior chemotherapy, or thoracic neck or radiotherapy
- •Evidence of any small cell histology
- •Prior or concurrent malignancy (except non-melanomatous skin cancer) unless disease-free for at least 5 years
