Mitotic Count Uveal Melanoma, the number of mitoses per 40 high-power fields (HPF) based on pathological evaluation, is a prognostic factor for uveal melanoma.
Mitotic Count Uveal Melanoma is listed as a Registry Data Collection Variable in AJCC. It was previously collected as Uveal Melanoma, CS SSF# 9.
0.0 0 mitoses per 40 high-power fields (HPF)
Mitoses absent, no mitoses present, no mitotic activity
0.1-99.9 0.1-99.9 mitosis per 40 HPF
XX.1 100 or more mitoses per 40 HPF
XX.2 Stated as low mitotic count or rate with no specific number
XX.3 Stated as high mitotic count or rate with no specific number
XX.4 Mitotic count described with denominator other than 40 HPF
XX.7 Test ordered, results not in chart
XX.8 Not applicable: Information not collected for this case
(If this information is required by your standard setter, use of code XX.8 may result in an edit error.)
