RATIONALE: Comparing results of diagnostic procedures, such as positron emission tomography, done before and after chemotherapy or surgery may help doctors predict a patient's response to treatment and help plan the best treatment. PURPOSE: This clinical trial studies positron emission tomography in monitoring treatment response in women with newly diagnosed breast cancer.
Detailed DescriptionPRIMARY OBJECTIVES:
Our overall goal is to develop a non-invasive means to monitor cancer treatment response to novel therapy.
The first goal of this study is to determine the sensitivity of FLT-PET in detecting invasive breast cancer.
The second goal is to determine the effectiveness of FLT-PET as a non-invasive means to monitor treatment response.
The third goal is to examine the effects of neoadjuvant therapy on the tumor microenvironment by measuring the change in tumor proliferation index with changes in fibroblast activation protein (FAP) expression.

An imaging technique using compounds labelled with short-lived positron-emitting radionuclides (such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18) to measure cell metabolism. It has been useful in study of soft tissues such as CANCER; CARDIOVASCULAR SYSTEM; and brain. SINGLE-PHOTON EMISSION-COMPUTED TOMOGRAPHY is closely related to positron emission tomography, but uses isotopes with longer half-lives and resolution is lower.
An imaging technique that combines a POSITRON-EMISSION TOMOGRAPHY (PET) scanner and a CT X RAY scanner. This establishes a precise anatomic localization in the same session.
An imaging technique using a device which combines TOMOGRAPHY, EMISSION-COMPUTED, SINGLE-PHOTON and TOMOGRAPHY, X-RAY COMPUTED in the same session.
A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.
