Prognostic Tree of Gimotty et al for a Patient with a Thin Primary Cutaneous Malignant Melanoma

Description

Gimotty et al developed a prognostic tree for evaluating patients with thin primary cutaneous malignant melanomas. This can help identify patients who will require closer monitoring. The authors are from the University of Pennsylvania in Philadelphia.

Patient selection: thin melanoma (<= 1.0 mm)

Parameters:

(1) mitotic rate

(2) growth phase

(3) gender

Mitotic Rate	Growth Phase	Gender	Risk Group
0	radial	NA	minimal
0	vertical	NA	low
> 0	NA	female	moderate
> 0	NA	male	high

where:

• The mitotic rate is only described as 0 or not. There is no description of number of microscopic fields examined, or microscopic field area. This implies that any mitotic activity conveys risk.

Risk Group	10 Year Risk of Metastasis
minimal	0.5%
low	4%
moderate	12.5%
high	31%
