Literature on non-ampullary-duodenal carcinomas is limited. We analyzed 47 resected non-ampullary-duodenal carcinomas. Histologically, 78% were tubular-type adenocarcinomas mostly gastro-pancreatobiliary type and only 19% pure intestinal. Immunohistochemistry (n=38) revealed commonness of 'gastro-pancreatobiliary markers' (CK7 55, MUC1 50, MUC5AC 50, and MUC6 34%), whereas 'intestinal markers' were relatively less common (MUC2 36, CK20 42, and CDX2 44%). Squamous and mucinous differentiation were rare (in five each); previously, unrecognized adenocarcinoma patterns were noted (three microcystic/vacuolated, two cribriform, one of comedo-like, oncocytic papillary, and goblet-cell-carcinoid-like)...

This work presents experimental and analytical comparison of terahertz transmission and reflection imaging modes for assessing breast carcinoma in excised paraffin-embedded human breast tissue. Modeling for both transmission and reflection imaging is developed. The refractive index and absorption coefficient of the tissue samples are obtained. The reflection measurements taken at the system's fixed oblique angle of 30° are shown to be a hybridization of TE and TM modes. The models are validated with transmission spectroscopy at fixed points on fresh bovine muscle and fat tissues...

In the USA alone, approximately 61,000 new diagnoses of ductal intraepithelial neoplasia 1c-3 (DIN) are made each year. Around 10-20 % of the patients develop a recurrence, about 50 % of which are invasive. Prior studies have shown that invasive breast carcinomas positive for p16 or p53 have a higher frequency of recurrence and a more aggressive course; however, the co-expression of these markers across the entire spectrum of DIN and its potential correlation with grade of the lesions has not been studied previously...

INTRODUCTION: The most common etiology for Oral Squamous Cell Carcinoma (OSCC) is tobacco and tobacco related products which cause nuclear damage to the keratinocytes. The chemical carcinogens not only affect the lining of oral epithelium but also affect the lining epithelium of the excretory ducts of the salivary glands. Thus, there is a possibility of epithelial dysplasia of the salivary duct epithelium which may lead to potential malignant transformation. AIM: The study was performed to see the changes in the minor salivary glands and excretory ducts in cases of oral epithelial dysplasia and OSCC...

A 79-year-old man underwent F-choline PET/CT for biochemical recurrence of prostate cancer. PET/CT images showed an area of elevated radiopharmaceutical uptake in a left pelvic node. In addition, a small focus of increased radiolabeled choline accumulation was seen in a small nodule of the right breast, which was later histologically characterized as an infiltrating ductal carcinoma. In this patient, choline PET/CT was critical in localizing prostate cancer recurrence and identifying a second unsuspected malignancy...

The present study evaluated the proteomic profile of saliva and plasma from women with impalpable breast lesions using nano-liquid chromatography-quadrupole-time-of-flight (nLC-Q-TOF) technology. Plasma and saliva from patients with fibroadenoma (n=10), infiltrating ductal carcinoma (n=10) and healthy control groups (n=8) were assessed by combinations of inter/intra-group analyses, revealing significant quantitative and qualitative differences. The major differentially-expressed proteins in the saliva of patients compared with the controls were α2-macroglobulin and ceruloplasmin, but the proteins that met the minimum fold-change and P-value cut-offs were leukocyte elastase inhibitor and α-enolase, and deleted in malignant brain tumors 1...

A patient without clinical symptoms had a mammogram in October 2008. The procedure caused intense persistent pain, swelling and development of a haematoma following mediolateral left breast compression. Three months later, a 9×11 cm mass developed within the same region. Core biopsies showed a necrotizing high-grade ductal carcinoma, with a high mitotic index. Owing to its extensive size, the patient began chemotherapy followed by trastuzumab and later radiotherapy to obtain clear margins for a subsequent mastectomy...

BACKGROUND: TBX3 is a T-box transcription factor repressor that is elevated in metastatic breast cancer and is believed to promote malignancy of tumor cells, possibly by promoting cell survival and epithelial-mesenchymal transition. METHODS: The relative expression of TBX3 was assessed in the 21T cell lines which were derived from an individual patient and represent three distinct stages of breast cancer progression: 21PT, atypical ductal hyperplasia; 21NT, ductal carcinoma in situ; and 21MT-1, invasive mammary carcinoma...

AIMS: Metaplastic breast carcinoma (MBC) is a rare subtype of breast carcinoma less responsive to conventional chemotherapy than ductal carcinoma. In molecular terms, MBCs usually cluster with triple-negative breast cancers (TNBCs), but have a worse prognosis than TNBCs. Studies investigating MBCs for specific biomarkers of therapy response are rare and limited by the methodological approaches. The aim of the present study was to characterise MBCs on a molecular level and test programmed death-ligand 1 (PD-L1) biomarker expression in MBCs for future therapeutic interventions...

In breast cancer, radiotherapy is an essential component of the treatment. After conservative surgery for an infiltrating carcinoma, radiotherapy must be systematically performed, regardless of the characteristics of the disease, because it decreases the rate of local recurrence and by this way, specific mortality. Partial breast irradiation could not be proposed routinely but only in very selected and informed patients. For ductal carcinoma in situ, adjuvant radiotherapy must be also systematically performed after lumpectomy...

Decoy Receptor 3 (DcR3), also called TNFRSF6β, is a member of the tumor necrosis factor receptor superfamily and is a soluble receptor for FasL. DcR3 is overexpressed in cancers and contributes to tumorigenesis through immune suppression and promotion of angiogenesis. We found that DcR3 is overexpressed in breast infiltrating ductal carcinoma (IDC) cells as compared with normal controls. We also conducted a case-control study analyzing associations of DcR3 polymorphisms with breast IDC risk. Subjects included 531 females with breast IDC and 592 age-matched healthy controls...

REFLEXIONS ABOUT NEW STRATEGIES OF RADIOTHERAPY FOR EARLY BREAST CANCER: Radiotherapy (RT) remains a major treatment element in early breast cancer, with a major impact on local control and survival. For ductal carcinoma in situ (DCIS), RT reduces local recurrence (LR) rates by 50 to 60 % after conservative surgery (both in situ and invasive). This was confirmed by four randomized trials and one meta-analysis. For infiltrating breast cancers (IBC), RT also reduces LR rates by 65 to 75 % after conservative surgery...

PURPOSE: Breast conserving treatment, consisting of lumpectomy followed by whole-breast irradiation, is considered the standard of care in early-stage breast cancer. Randomized studies have reported that delivering boost doses to tumor bed improves local control rates, particularly in young women. This study sought to evaluate local control and cosmetic results of delivering boost doses using a high-dose-rate (HDR) brachytherapy (HDRBT) in breast cancer conservative treatment. METHODS: We included 621 T1-T2, N0-N1 breast cancer patients who underwent lumpectomy, external irradiation (44Gy over 5weeks), and a boost dose of two fractions of 5Gy to the tumor bed by means of HDR iridium brachytherapy...

B7-H4 is a co‑inhibitory molecule of the B7 family, which is expressed on antigen‑presenting cells (APCs) and is able to limit the T‑cell immune response. Macrophages act as professional APCs and are important for immunoregulation of the tumor microenvironment in breast cancer. In order to identify the association between the presence of B7‑H4 on macrophages and infiltrating ductal carcinoma (IDC), the present study investigated the expression of B7‑H4 on macrophages with different polarizations. The expression levels of B7‑H4 in IDC tissues were determined using immunohistochemistry, and the expression of B7‑H4 on macrophages in the breast IDC microenvironment were determined using western blot analysis and reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR)...
