Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
To perform analyses using microarray-based gene expression profiling to determine whether a unique mRNA and microRNA gene expression profile distinguishes LCIS from normal breast epithelium and from invasive carcinoma.
2 years
Secondary Outcomes (4)
To perform analyses using microarray-based mRNA and microRNA gene expression profiling to identify distinct molecular subtypes within LCIS.
2 years
Deter the nature or extent of molecular genetic alterations in LCIS as asses by mRNA & microRNA microarray canbe correl with the risk of subsequent invas breast cancer in pts with class type LCIS & those with newly described histologic variants of LCIS.
2 years
To prospectively follow patients diagnosed with newly described histologic variants of lobular carcinoma in situ, who do or do not undergo surgery for treatment or prevention, to better characterize this lesion and its behavior.
2 years
To further characterize the invasive lobular breast cancers that develop in association with LCIS as assessed by standard histopathology and immunohistochemistry.
2 years
Study Arms (1)
LCIS diagnosis
Patient with LCIS diagnosis
Interventions
Human tissues taken after the clinically indicated removal of these tissues from patients as part of their routine care.
Eligibility Criteria
Women seen at MSKCC breast clinic
You may qualify if:
- multifocal lobular carcinoma in situ treated with prophylactic mastectomy or lumpectomy
- invasive breast cancer (lobular or ductal) with coexisting lobular carcinoma in situ treated with mastectomy or lumpectomy
- biopsy proven, untreated lobular carcinoma in situ
- invasive lobular cancer with or without coexisting lobular carcinoma in situ treated with mastectomy or lumpectomy
You may not qualify if:
- no paraffin blocks available
- no residual lobular carcinoma in situ in paraffin blocks
