Ki-67(MIB-1 clone) is a monoclonal antibody that reacts with cells undergoing DNA synthesis by binding to the Ki-67 antigen, a marker known to be expressed only in proliferating cells. By measuring the amount of tumor cells expressing Ki-67, an estimate of DNA synthesis can be determined. Studies suggest that Ki-67(MIB-1) analysis of paraffin-embedded tissue specimens may provide useful prognostic information in various tumor types.
Reference Values

Results will be reported as a percentage of tumor cells staining positive for Ki-67(MIB-1). Quantitative Ki-67(MIB-1) results should be interpreted within the clinical context for which the test was ordered.
Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

The paraffin block analyzed must be representative of the patient's tumor.
Test results should be interpreted in the context of clinical findings and other laboratory data.
Due to the limitations of the Aperio system (fixed rectangle size and the inability of the machine to distinguish stroma, benign, etc.) small/focal tumors will be converted to a manual semiquantitation by a pathologist rather than an automated measurement.

Method Description

Describes how the test is performed and provides a method-specific reference
A 4-micron thick section is cut from the paraffin block. The section is stained with an immunoperoxidase method using the monoclonal antibody Ki-67 (MIB-1 clone). This is the paraffin nuclear epitope to the Ki-67 antigen. Any nucleus that has an antigen-antibody complex will cause the bright-field, brown chromogen, diaminobenzidine (DAB), to precipitate onto it. All nuclei, both DAB-positive and -negative, are counterstained with diluted hematoxylin.
Ki-67 (MIB-1) quantification using the Aperio system in neuroendocrine tumors has been validated by our laboratory. Ki-67(MIB-1)-stained slides are scanned using the Aperio ScanScope instrument, which captures digital images of the patient slide. A technologist views the digitized image and selects the most intensely stained area ("hot-spot") within the tumor. Then, using a rectangle tool available in ImageScope (Aperio Technologies Inc), lays up to ten annotations in this "hot-spot," which are analyzed using an image analysis algorithm that renders the percentage of positive staining tumor nuclei. The slides, images, and test results are then reviewed by a pathologist who provides a final interpretation.(Unpublished Mayo method)

Day(s) Performed
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.
