简要总结
RATIONALE: Diagnostic procedures, such as positron emission tomography (PET) using 3'-deoxy-3'-(18F) fluorothymidine, may be effective in assessing the response to chemotherapy before surgery in treating locally advanced breast cancer.
PURPOSE: This clinical trial is studying how well positron emission tomography using 3'-deoxy-3'-(18F) fluorothymidine works in treating women with locally advanced cancer in one breast who are receiving chemotherapy.
详细描述
OBJECTIVES:
Primary
- Evaluate the efficacy of positron emission tomography (PET) utilizing 3'-deoxy-3'-(18F) fluorothymidine (^18F-FLT) to correctly identify response to neoadjuvant chemotherapy in women with locally advanced unilateral breast cancer.
- Correlate PET-^18F-FLT results with histological response.
Secondary
- Evaluate the correlation of early changes in tumor uptake of ^18F-FLT after the first course of chemotherapy with complete response after treatment completion.
- Evaluate the correlation of early changes in tumor uptake of ^18F-FLT with histologic response in biopsies obtained after 1 course of chemotherapy.
- Determine if the initial intensity of tumor uptake is a predictive value of response to chemotherapy.
- Determine if initial intensity of tumor uptake of ^18F-FLT varies according to histologic type of tumor, indices of proliferation, and tumor cellularity before therapy.
- Determine if the tumor uptake of ^18F-FLT during therapy varies according to histologic type of tumor, indices of proliferation, and tumor cellularity before therapy.
- Evaluate the role of TK1 on the kinetics of ^18 F-FLT.
- Analyze serum.
- Research biomarkers of genomics, transcription, and proteomics.
- Evaluate the toxicity of ^18F-FLT.
