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.)
