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.
