Project description:CN profiles of invasive lobular breast cancer with variant growth pattern display common CN loss of chromosome 16q. Affymetrix Oncoscan arrays were performed according to the manufacturer's directions on DNA extracted from FFPE-breast cancer tissues.
Project description:We analysed a cohort of breast papillary lesions cases with (n=4) or without (n=7) co-existed cancer for genome-wide copy number and loss of heterozygosity using Affymetrix OncoScan® MIP arrays. Cases included pure papilloma (withoout cancer) (n=7), papilloma cases synchronous with cancer (n=4). We have analysed copy number calling from these samples including carcinoma components of synchronous cases in order to understand the precursor relationship as well any biomarker for progression from papillary lesions to carcinoma.
Project description:Expression profiling of papillary carcinoma of the breast and grade- and ER-matched cases of invasive ductal breast cancer To identify differential expression between papillary carcinomas of the breast and grade- and ER-matched invasive ductal breast cancers, we performed expression profiling of 16 cases of papillary carcinomas of the breast and 16 cases of grade- and ER-matched invasive ducatal carcinoma of no special subtype. We further reviewed the papillary carcinomas of the breast and classified them into 3 subtypes, namely, invasive papillary carcinoma, encapsulated papillary carcinoma and solid papillary carcinoma. We also performed a hypothesis-generating comparison of differential expression between the 3 subtypes of papillary carcinoma of the breast.

Expression profiling of 16 cases of papillary carcinioma of the brest and 16 cases of invasive ducal carcinomas using the Illumina HT-12 v4 arrays
Project description:Clear cell papillary renal cell carcinoma (CCPRCC) is a low-grade renal neoplasm with morphological characteristics mimicking both clear cell renal cell carcinoma (CCRCC) and papillary renal cell carcinoma (PRCC). However, despite some overlapping features, their morphological, immunohistochemical, and molecular profiles are distinct. To better understand the biology of this tumor, we analyze the miRNA expression profiles of a set of CCPRCC by microarrays.
Project description:Breast cancer tumors of ductal (D) and lobular (L) type. Not all lobular tumors are "classical lobular" tumors. Experiment "BC2_Jeffrey_minus_G50_1" was denoted as BC-D-002.
Project description:The Lung3 data set consists of 89 NSCLC patients that were treated at MAASTRO Clinic, The Netherlands. For these patients pretreatment CT scans, tumour delineations and gene expression profiles were available. We used this data set to associate imaging features with gene-expression profiles. 89 samples from NSCLC patients. Samples were obtained by biopsies from cancerous tissue. Tumors were classified as Adenocarcinoma, Papillary, NOS; Squamous Cell Carcinoma, NOS; Non-Small Cell; Papillary Type; or Solid Type.
Project description:With the intent of identify alterations associated with the development of distant metastases in Papillary Thyroid Cancer (PTCs), we design a case-control study and performed genome-wide copy number variation analysis by Affymetrix Oncoscan FFPE Kit on 34 PTCs that developed distant metastases (DM-PTCs), 61 PTCs without distant metastases (CTRL-PTCs), and on 7 tissue from distant metastatic site
