Active clinical trials for "Carcinoma, Lobular"

This study is being done in order to better understand the biology of an abnormal lesion found in breast tissue called "lobular carcinoma in situ" (LCIS). We are interested in studying LCIS. The LCIS is not a cancer itself, but is a marker for an increased risk of cancer. We would like to look for LCIS in breast tissue removed during surgery from patients with cancer or at high risk for cancer. If LCIS is found, we will search for genes that are expressed (turned on or off) differently than in normal breast tissue. The identification of such genes would help us better understand the biology of LCIS, and its possible relationship to breast cancer.

RATIONALE: Gathering information about genetic changes in patients with lobular carcinoma in situ of the breast may help doctors learn more about the disease and find better methods of treatment. PURPOSE: This clinical trial is studying the genetics of women with lobular carcinoma in situ of the breast.

F18-FDG is the widely used PET tracer in the routine practice of oncologic disease imaging using the technology of PET-CT. However, FDG-avidity is a characteristic of the individual tumor. There are various types of human malignancies, which are not taking FDG in access. In these cases FDG is not a sensitive tracer of imaging. In search for other tumor PET tracers, C11-Acetate has been shown recently in a few early studies to have a potential value in imaging of non-FDG-avid tumors. The purpose of the current study is to assess the role of 11C-acetate PET in various tumors, which often are not detected by 18F-FDG and were not widely assessed until now.
