We present a label-free, chemically-selective, quantitative imaging strategy to identify breast cancer and differentiate its subtypes using coherent anti-Stokes Raman scattering (CARS) microscopy. Human normal breast tissue, benign proliferative, as well as in situ and invasive carcinomas, were imaged ex vivo. Simply by visualizing cellular and tissue features appearing on CARS images, cancerou...

We investigated the correlations between growth patterns and E-cadherin expression by immunohistochemistry and the presence of mutations of exons 6-10 of the E-cadherin gene by PCR-SSCP, in 79 cases of invasive lobular and ductal breast cancer. E-cadherin expression showed a tendency to be lower in lobular than in ductal carcinomas (p=0.064). In 60% of lobular carcinomas the diffuse growth patt...

Invasive lobular cancer (ILC) tends to be significantly larger in size with significantly more positive lymph nodes, whereas ILC has a significantly more favorable outcome, compared to stage-matched invasive ductal carcinoma (IDC). The mechanism accounting for such differences remains elusive. Based on morphological, immunohistochemical, and molecular studies of over 1,000 cases of human breast...

Breast cancer is the most prevalent cancer in women worldwide and is classified into ductal and lobular carcinoma. Breast cancer as well as lobular carcinoma is associated with various risk factors such as gender, age, female hormone exposure, ethnicity, family history and genetic risk factor-associated genes. Genes associated with a high risk of ...

Expression of high levels of fatty acid synthase (FAS), an important enzyme in fatty acid synthesis, has been identified in a wide variety of human carcinomas. In breast and prostate carcinoma, FAS expression appears to be associated with aggressive disease. Recent biochemical studies have demonstrated that FAS expression in cancer cells connotes activation of the entire fatty acid synthesis pa...

The early proliferative lesions of the breast have taken on greater significance as a result of mammographic screening and the use of even more sensitive imaging technologies. The intraductal proliferative lesions of the breast are a group of cytologically and architecturally diverse proliferations, typically originating from the terminal duct-lobular unit and confined to the mammary duct-lobul...

Background: Lung cancer is the leading cause of cancer-related mortality worldwide. Thin-walled cystic lung with ground glas s opacity (GGO) a type carcinoma specific computed tomography (CT) features. Objectives: To investigate imaging features multi-slice spiral (MSCT) GGO and to improve diagnosis this cancer. Patients Methods: The clinical data 24 patients pathologically confirmed thin-walle...

BACKGROUND Hereditary diffuse gastric carcinoma is an autosomal dominant cancer syndrome associated with mutations of the E-cadherin gene (CDH1). E-cadherin is normally involved in cell-cell adhesion, so it not surprising that individuals with this syndrome are predisposed to develop malignancies with dyshesive morphologies at a young age, such as diffuse (signet ring cell) gastric carcinoma an...

Pleomorphic lobular carcinoma of the breast has been identified as a histological variant of infiltrating lobular carcinoma (ILC) with poor prognosis. Thus, cytological recognition of this tumour is important. It is characterized by pleomorphism to a degree that contrasts with the cytologic uniformity of classic ILC. Due to this feature it is often misinterpreted as infiltrating ductal carcinom...

Primary Breast Cancer, Urokinase-Type Plasminogen Activator, Inhibitors The aim of the study was to monitor urokinase plasminogen activator antigen concentrations and its type 1 (PAI-1) and type 2 (PAI-2) inhibitors in histologically defined forms of primary breast cancer and a comparison with these antigens levels in normal tissue. Another goal was a search for a relationship/or its lack/betwe...
