  Purpose

In about half the cases of breast cancer, there is hypoxic (no, or little oxygen) tissue present. Hypoxic cells can be resistant to treatment and may cause increased tumour growth. This study will use 18F-FAZA PET scans before surgery or treatment to assess whether patients have hypoxic tumours. The results will be compared to tissue samples removed during surgery and to the distribution of 18F-FDG.

Primary Outcome Measures:
  • Uptake of 18F-FAZA (RUS and T/B) and its correlation to tumour size, auxiliary nodal status, tumour grade, EP/PR, and HER-2 status, Ki-67, Androgen receptor status (AR), vimentin and basal keratins, HIF-1 a and glomeruloid microvascular proliferation. [ Time Frame: 5 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • General biodistribution of 18F-FAZA and FluGlucoScan Injection [ Time Frame: 5 years ] [ Designated as safety issue: No ]
  • Comparison of pre-operative 18F-FAZA and FluGlucoScan Injection PET images [ Time Frame: 5 years ] [ Designated as safety issue: No ]

Estimated Enrollment: 30
Study Start Date: November 2008
Estimated Study Completion Date: October 2014
Estimated Primary Completion Date: October 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
18F-FAZA + FluGlucoScan Injection
Drug: 18F-FAZA PET scan
Radioactive dose of 18F-FAZA: 110-600 MBq per injection. One pre-treatment injection of 18F-FAZA and PET scan will be permitted per patient.
Drug: FluGlucoScan Injection (18F-FDB) PET scan
Radioactive dose of 100-700 MBq per injection. A single pre-treatment injection of FluGlucoScan Injection and PET scan will be permitted per patient.

Detailed Description:

Hypoxia or anoxia can be found in 50% of locally advanced breast carcinomas. Assessment of pre-treatment in viva and in vitro hypoxia could allow patient selection for more aggressive therapy or clinical trails focused on targeting hypoxia. We will use the PET radiotracer 18F-FAZA to monitor hypoxia in the protocol. We will study pathological characteristics on the final tumour restriction specimen and correlate prognostic and predictive factors with PET scan data. Tumour banking is optional.
