Some reports have suggested that proliferation indices may be of value, but the data are conflicting and the methods of assessment often poorly defined. In this study the mitotic activity and Ki-67 immunohistochemistry was assessed in a series of GCT using carefully specified methodology, and the findings were correlated with clinicopathological findings.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>\n                      Tumour proliferation was assessed in 38 primary GCT by counting mitotic figures in 50 high-power fields (\u00d7500 magnification) with results expressed as a mean count per 2 mm\n                      <jats:sup>2<\/jats:sup>\n                      standardised area.
