Mitotic Rate Melanoma, the number of mitoses per square millimeter based on pathological evaluation, is a prognostic factor for melanoma of the skin.
Mitotic Rate Melanoma is a Registry Data Collection Variable in AJCC. It was previously collected as Melanoma Skin, CS SSF# 7.
|00||0 mitoses per square millimeter (mm)
No mitoses present
|01-99||1 - 99 mitoses/square mm
(Exact measurement in mitoses/square mm)
|X1||100 mitoses/square mm or more|
|X2||Stated as "less than 1 mitosis/square mm"
Stated as "nonmitogenic"
|X3||Stated as "at least 1 mitosis/square mm"
Stated as "mitogenic"
|X4||Mitotic rate described with denominator other than square millimeter (mm)|
|X7||Test ordered, results not in chart|
|X8||Not applicable: Information not collected for this case
(If this information is required by your standard setter, use of code X8 may result in an edit error.)
|X9||Not documented in medical record
