Prognostic Model of Schuchter et al for Predicting 10 Year Survival in Patients with Primary Melanoma

Description

Schuchter et al developed a prognostic model for predicting 10 year survival in patients with primary cutaneous malignant melanoma. This can help identify patients at risk for recurrence for whom adjuvant therapy may be beneficial. The authors are from the University of Pennsylvania, The Lombardi Cancer Center, and Beth Israel Hospital.

Parameters:

(1) lesion thickness

(2) location of lesion

(3) age at diagnosis

(4) gender

Parameter	Finding	Points
thickness of the lesion	< 0.76 mm	3.93
	0.76 to 1.69 mm	2.25
	1.70 mm to 3.60 mm	1.07
location of primary lesion	on an extremity	1.47
	not on an extremity	0
age at diagnosis	<= 60 years of age	1.1
	> 60 years of age	0
gender of patient	female	0.71
	male	0

X =

= SUM(points for the 4 parameters) – 2.245

probability of surviving 10 years =

= 1 / (1 + EXP((-1) * X)
