Molecular Genetic Basis of Invasive Breast Cancer Risk Associated With Lobular Carcinoma in Situ

This study is ongoing, but not recruiting participants.

NCT00581750

  Purpose
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.

Primary Outcome Measures:
  • 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. [ Time Frame: 2 years ]

Secondary Outcome Measures:
  • To perform analyses using microarray-based mRNA and microRNA gene expression profiling to identify distinct molecular subtypes within LCIS. [ Time Frame: 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. [ Time Frame: 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. [ Time Frame: 2 years ]
  • To further characterize the invasive lobular breast cancers that develop in association with LCIS as assessed by standard histopathology and immunohistochemistry. [ Time Frame: 2 years ]

Detailed Description:
LCIS) is a monoclonal pathologic entity which is subject to characterization at the molecular genetic level, and that these molecular genetic alterations may be used to predict the subsequent development of invasive breast cancer. Prophylactic mastectomy specimens from women with multifocal LCIS, and invasive breast cancer specimens which display coexisting LCIS, will be examined for X-chromosome inactivation patterns and loss of heterozygosity to assess for monoclonality. If clonality is present, we will assess for microsatellite instability, and a microarray-based comparative genomic hybridization (CGH) technique will be used to identify genetic alterations present in LCIS. Lastly, LCIS biopsy specimens from untreated patients who, after follow-up did or did not develop invasive breast cancer, will be evaluated to determine whether the nature or extent of any identified genetic alterations can be correlated with the subsequent development of invasive breast cancer. We hypothesize that a fraction of LCIS lesions will reflect a monoclonal origin, that those lesions of monoclonal origin will display evidence of specific molecular genetic alterations, and that these specific alterations will correlate with the likelihood of the subsequent development of invasive breast carcinoma.
