High mitotic count
WebA high-power field ( HPF ), when used in relation to microscopy, references the field of view under the maximum magnification power of the objective being used. Often, this represents a 400-fold magnification when referenced in scientific papers. Area [ edit] Area per high-power field for some microscope types: WebAn elevated mitotic index indicates more cells are dividing. In cancer cells, the mitotic index may be elevated compared to normal growth of tissues or cellular repair of the site of an injury.[2] The mitotic index is therefore an important prognosticfactor predicting both overall survival and response to chemotherapy in most types of cancer.
