Proliferative activity in human breast cancer: Ki-67 automated evaluation and the influence of different Ki-67 equivalent antibodies
BACKGROUND Ki67 labeling index (Ki67 LI), the percentage Ki67 immunoreactive cells, is a measure of tumor proliferation, with important clinical relevance in breast cancer, and it is extremely important to standardize its evaluation. AIM To test the efficacy of computer assisted image analysis (CAIA) applied to completely digitized slides and to assess its feasibility in routine practice and ...
متن کاملComparison of Ki-67 equivalent antibodies.
AIMS To compare commercially available Ki-67 equivalent antibodies with regard to qualitative and quantitative immunohistochemical staining characteristics. METHODS The following antibodies were used: monoclonal MIB-1 (Immunotech), monoclonal MM1 (Novocastra), polyclonal NCL-Ki-67p (Novocastra), and polyclonal Rah Ki-67 (Dako). All immunostainings were evaluated in squamous epithelium from fo...
متن کاملThe role of Ki-67 in breast cancer.
The proliferative marker, Ki-67, is a human nuclear antigen, and forms an integral part of cell division in both normal and malignant tissue. Since the hallmark of cancer is uncontrolled and relentless cell proliferation, the Ki-67 proliferative index is increasingly used to assess and manage breast cancer. The value of Ki-67 as a prognostic indicator, a guide to the selection of therapy, and a...
متن کاملSemi-automated evaluation of Ki-67 index in invasive ductal carcinoma of the breast
A significant factor that affects the value of the Ki-67 proliferation index (IK) is the interpretation and implementation approach. This method is based on visual or automated methods to count tumor nuclei labeled with Ki-67 antigen, and is prone to errors. Detection of Ki-67 is a useful tool in breast cancer and contributes to its molecular classification. The current study proposes a method ...
متن کاملCelecoxib decreases Ki-67 proliferative index in active smokers.
PURPOSE This study evaluated the feasibility of cyclooxygenase-2 (COX-2) inhibition for lung cancer chemoprevention. We hypothesized that treatment with oral Celecoxib, a selective COX-2 inhibitor, would favorably alter the biomarkers of lung cancer risk as measured by the Ki-67 proliferative labeling index (Ki-67 LI). EXPERIMENTAL DESIGN Twenty active heavy smokers were enrolled into a pilot...
