  Purpose
This study will investigate the sensitivity and specificity of FLT-PET/CT in primary breast cancer detection and in the use of FLT-PET in monitoring how well a breast tumor respond to treatment. We will compare this technique with other imaging modalities as well as with tissue collection (during a biopsy). We will recruit women with a newly diagnosed invasive breast cancer, who are able to tolerate undergoing a PET/CT (possibly two scans) scan,

Primary Outcome Measures:
  • Sensitivity and specificity of FLT-PET comparing with standard FDG-PET
  • Correlate SUV with % Ki67 nuclear stain

Secondary Outcome Measures:
  • Change in SUV with change in tumor proliferation index (%Ki67 nuclear stain) (when neoadjuvant therapy is used)
  • Tumor volume pre and post chemotherapy as assessed by clinical exam, breast imaging studies, histopathological examination, and breast cancer outcome parameters (when neoadjuvant therapy is used)

Enrollment: 0
Study Start Date: March 2009
Study Completion Date: June 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm I
Patients undergoing definitive surgery after cancer diagnosis undergo 3'-deoxy-3'-[18F] fluorothymidine (FLT)-PET prior to definitive surgery. Patients undergoing neoadjuvant chemotherapy prior to definitive surgery undergo FLT-PET prior to and after completion of neoadjuvant chemotherapy
Other: 3'-deoxy-3'-[18F]fluorothymidine
Given IV
Other Name: 18F-FLT
Procedure: Positron Emission Tomography/computed tomography Radiation: FLT-PET/CT

Detailed Description:
Our overall goal is to use this clinical trial as a platform to validate fibroblast activation protein (FAP) as a biomarker for the tumor microenvironment and to explore the dynamic interaction between proliferating tumor cells and the tumor microenvironment. Our long term goal is to develop new drugs that will target the tumor microenvironment as novel therapeutic and chemoprevention strategies.
