Mitotic activity was evaluated as the number of mitotic figures per 10 high-power fields (mitotic activity index) or per 1000 tumor cells (mitotic index). Counting was carried out blindly by two observers. A high correlation was observed between the two determinations (rs = .96, P < .001). For clinical analysis, three mitotic activity index subgroups (mitotic figures/field ≤ 9, 10–19 and more than 19, according to grading criteria) and three mitotic index subgroups (percentage of mitotic figures less than 0.10, 0.11–0.50 and more than 0.50, according to tertile criteria) were considered.
