The spectrum of genomic alterations in ductal carcinoma in situ (DCIS) is relatively unexplored, but is likely to provide useful insights into its biology, its progression to invasive carcinoma and the risk of recurrence. DCIS (n=20) with a range of phenotypes was assessed by massively parallel sequencing for mutations and copy number alterations and variants validated by Sanger sequencing. PIK3CA mutations were identified in 11/20 (55%), TP53 mutations in 6/20 (30%), and GATA3 mutations in 9/20 (45%). Screening an additional 91 cases for GATA3 mutations identified a final frequency of 27% (30/111), with a high proportion of missense variants (8/30)...

Formalin-fixed paraffin-embedded (FFPE) specimens, when used in conjunction with patient clinical data history, represent an invaluable resource for molecular studies of cancer. Even though nucleic acids extracted from archived FFPE tissues are degraded, their molecular analysis has become possible. In this study, we optimized a laboratory-based next-generation sequencing barcoded cDNA library preparation protocol for analysis of small RNAs recovered from archived FFPE tissues. Using matched fresh and FFPE specimens, we evaluated the robustness and reproducibility of our optimized approach, as well as its applicability to archived clinical specimens stored for up to 35 years...

G2 ductal infiltrating carcinomas are a heterogeneous group of tumours with ambiguous clinical significance. This is because G2 carcinomas are almost always the largest category and poorly reproducible. Mitotic count (MC) is one of the causes of poor histological grading reproducibility. The phosphoistone H3 (PPH3) antibody improves identification of mitotic figures. The aim of our study is to demonstrate whether using a new histological grading system based on PPH3 immunostaining to assess MC can re-stratify G2 category...

OBJECTIVE: Breast carcinoma is the most common malignant tumor detected in women. The hypothesis that increased levels of adhesion molecules and Cathepsin D affect cancerous cells moving away the primary tumor and contributes to migration of the cancerous cell and may cause remote organ metastases is defended. The aim of the present study was to search the association of intracellular adhesion molecule-1 (ICAM-1), vascular adhesion molecule-1 (VCAM-1), Cyclin D1, cathepsin D immunohistochemically with clinicopathological parameters in the patients diagnosed with invasive ductal breast carcinoma...

BACKGROUND: Peptidylarginine deiminase (PAD) catalyzes the conversion of arginine residues to citrulline residues, termed citrullination. Recent studies have suggested that PAD isoform 2 (PADI2) plays an important role in tumors, although its tumorigenic effect and mechanism are largely unknown. MATERIALS AND METHODS: Immunohistochemistry and enzyme-linked immunosorbent assay (ELISA) were used to investigate the expression level of PADI2 in various tumor tissues and patient blood samples, respectively...

BACKGROUND: Normal myoepithelial cells (MECs) play an important tumour-suppressor role in the breast but display an altered phenotype in ductal carcinoma in situ (DCIS), gaining tumour-promoter functions. Matrix metalloproteinase-8 (MMP-8) is expressed by normal MECs but is lost in DCIS. This study investigated the function of MMP-8 in MECs and the impact of its loss in DCIS. METHODS: Primary normal and DCIS-associated MECs, and normal (N-1089) and DCIS-modified myoepithelial (β6-1089) cell lines, were used to assess MMP-8 expression and function...

Breast cancer is the leading cause of cancer-related death in women worldwide. Invasive ductal carcinoma (IDC) is the most frequent invasive form of breast cancer followed by metastasis. There is no accepted marker for distinguishing this form from other less aggressive forms of breast cancer. Therefore, finding new markers especially molecularly detectable ones are noteworthy. It has been shown that NOTCH1 has been overexpressed in the patients with breast cancer, but no study has investigated the expression of NOTCH1 and its correlation with other molecular and hormonal markers of breast cancer so far...

BACKGROUND: Autotransplantation of frozen-thawed ovarian tissue is a method to preserve ovarian function and fertility in patients undergoing gonadotoxic therapy. In oncology patients, the safety cannot yet be guaranteed, since current tumor detection methods can only exclude the presence of malignant cells in ovarian fragments that are not transplanted. We determined the need for a novel detection method by studying the distribution of tumor cells in ovaries from patients with breast cancer...

BACKGROUND: Tumour infiltrating lymphocytes are an important component of the immune response to cancer and have a prognostic value in breast cancer. Although several studies have investigated the role of T-lymphocytes in breast cancer, the role of B lymphocytes (TIL-Bs) in Ductal carcinoma in situ (DCIS), remains uncertain. This study aimed to assess the role of TIL-Bs in DCIS. METHODS: 80 DCIS cases (36 pure DCIS and 44 mixed with invasive cancer) were immunohistochemically stained for B lineage markers CD19, CD20 and the plasma cell marker CD138...

The morphology of breast tumors is complicated and diagnosis can be difficult. We present here a novel diagnostic model which we validate on both array-based and RNA sequencing platforms which reliably distinguishes this tumor type across multiple cohorts. We also examine how this molecular classification predicts sensitivity to common chemotherapeutics in cell-line based assays. A total of 1845 invasive breast cancer cases in six cohorts were collected, split into discovery and validation cohorts, and a classifier was created and compared to pathological diagnosis, grade and survival...
