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. WebApr 25, 2011 · Our study confirms that, in patients with a localized primary melanoma, a high tumor mitotic rate reflects a more aggressive tumor that is associated with a worse survival outcome; conversely, a low mitotic rate is associated with a better outcome. A gradient of increasing mitotic rate with increasing tumor thickness was observed.
